2. Introduction
2.1. Who should read this manual?
This manual is aimed at everyone who is interested in automatic software distribution with opsi. The focus of the documentation is the explanation of the technical background, in order to contribute to an understanding of the processes.
This manual should not only support the system administrator who works practically with opsi, but also give prospective users a concrete overview of opsi in advance.
2.2. Conventions in text and graphics
Names which are shown in <angle brackets> have to be replaced by a real name.
Example: The file share on which the opsi software packages are located is called <opsi-depot-share> and is located on a real server on /var/lib/opsi/depot.
The software package: <opsi-depot-share>/ooffice is actually under /var/lib/opsi/depot/ooffice.
Examples from program code or configuration files use a Courier font and are highlighted in color.

3. Overview of opsi
Tools for automated software distribution and operating system installation are important and necessary tools for standardization, maintainability and cost saving of larger PC networks. Normally the application of such tools comes along with substantial royalties, whereas opsi as an open source tool affords explicit economics. Expenses thereby arise only from performed services like consulting, training and maintenance, and perhaps from low cofunding rates if you like to use some of the non free modules.
Although the software itself and the handbooks are free of charge, the process of introducing any software distribution tool is still an investment. To get the benefit without throwbacks and without a long learning curve consulting and education of the system administrators by a professional partner is recommended. uib offers all these services around opsi.
The opsi system as developed by uib depends on Linux-servers. They are used for remote installation and maintenance of the client OS and the client software packets ("PC-Server-Integration"). It is based as far as possible on free available tools (GNUtools, SAMBA etc.). The complete system all together is named opsi (Open PC-Server-Integration) and with its configurability is a very interesting solution for the administration challenges of a large computer park.
3.1. Experience
opsi is derived from a system, which is in use since the middle of the 90’s with more than 2000 Client-PCs in different locations of a state authority. Since that time it has continuously been adapted to the changing Microsoft operating system world. As a product opsi is now accessible for a broad range of interested users.
You can find an geographical overview of the registered opsi-installations at: opsi-map

3.4. Structure
The configuration of opsi requires some data management. All non-server components are using a web service for data exchange with the opsi server. They exchange data via the opsiconfd, and the opsiconfd forwards the data to the backend manager which passes the data into the selected backend.
opsi supports different backends: Backends:
-
File based
-
MySQL based
More details you will find at Section 5.6, “opsi data storage (backends)”.
The backend configuratin will be found at the files in ther directories
/etc/opsi/backendManager and /etc/opsi/backends.
The configuration files in /etc/opsi/backends define the backends.
Which backend is used for which data, is configured in the file
/etc/opsi/backendManager/dispatch.conf.
The file /etc/opsi/backendManager/acl.conf defines who has access to which
methods.
Below the directory /etc/opsi/backendManager/extend.d there could be files
which defines extended opsi methods. So you will find here for example the files which define the action based (legacy) methods by mapping them to the object based methods (/etc/opsi/backendManager/extend.d/20_legacy.conf).
A more detailed reference of these configuration files you will find at
4. opsi-Management GUI: opsi-configed
4.1. Requirements and operation
Since version 4.0.7.5.22, the opsi-configed requires at least Java 1.8
It works with the data from a running opsiconfd at least of version 4.0.6.
|
In non-opsi systems the opsi-configed can be simply installed by copying the required jar archive files as contained e.g. in the opsi-package.
In order to automate this you find will two helpers at https://download.uib.de/opsi4.1/misc/helper/: the setup program opsi-configed-setup.exe works for Microsoft Windows and opsi-configed-linux-setup.tar.gz works for various Linux systems.
If the client has a graphical desktop opsi-configed can be started from a start menu entry.
On Linux it can be started in a shell by executing /usr/bin/opsi-configed.
With non-gui servers there exist only the special non-gui start options
-
--version
-
--help bzw. -h
-
--querysavedsearch [SAVEDSEARCH_NAME] bzw. -qs [SAVEDSEARCH_NAME]
-
--swaudit-pdf FILE_WITH_CLIENT_IDS_EACH_IN_A_LINE [OUTPUT_PATH]
If the additional required jar archives exist in the path the opsi-configed can be started simply by java -jar configed.jar.
With java -jar configed.jar --help you’ll get a list of the command line options
.
-l LOC --locale LOC Set locale LOC (format: <language>_<country>)-h HOST --host HOST Configuration server HOST to connect to
-u NAME --user NAME User for authentication
-p PASSWORD --password PASSWORD password for authentication
-c CLIENT --client CLIENT CLIENT to preselect
-g CLIENTGROUP --group CLIENTGROUP CLIENTGROUP to preselect
-t INDEX --tab INDEX Start with tab number INDEX, index counting starts with 0, works only if a CLIENT is preselected
-d PATH --logdirectory PATH Directory for the log files
-r REFRESHMINUTES --refreshminutes REFRESHMINUTES Refresh data every REFRESHMINUTES (where this feature is implemented, 0 = never)
-qs [SAVEDSEARCH_NAME] --querysavedsearch [SAVEDSEARCH_NAME] On command line: tell saved host searches list resp. the search result for [SAVEDSEARCH_NAME])
--gzip [y/n] Activate gzip transmission of data from opsi server yes/no
--sslversion PREFERRED_SSL_VERSION Try to use this SSL/ TLS version
--ssh-key SSHKEY full path with filename from sshkey used for authentication on ssh server
--ssh-passphrase PASSPHRASE passphrase for given sshkey used for authentication on ssh server
--version Tell configed version
--collect_queries_until_no N Collect the first N queries; N = -1 (default, no collect), 0 = infinite
--help Give this help
--loglevel L Set logging level L, L is a number >= 0, <= 5
--halt Use first occurring debug halt point that may be in the code
--sqlgetrows Force use sql statements by getRawData
--nosqlrawdata Avoid getRawData
--localizationfile EXTRA_LOCALIZATION_FILENAME Use EXTRA_LOCALIZATION_FILENAME as localization file, the file name format has to be: configed_LOCALENAME.properties
--localizationstrings Show internal labels together the strings of selected localization
--swaudit-pdf FILE_WITH_CLIENT_IDS_EACH_IN_A_LINE [OUTPUT_PATH] export pdf swaudit reports for given clients (if no OUTPUT_PATH given, use home directory)4.1.1. Logging of the opsi-configed
By default, the opsi-configed uses its log level 3 "Info". The level can be raised to 4 "Check" or 5 "Debug".
To change the log level the command line option --loglevel [LEVEL] can be used. It is not recommended to set level 5 as long as not the start process needs to be inspected. For, with level 5, the produced log file is very large; it is difficult to get loaded and viewed. When the opsi-configed is running and a potential error situation is expected the log level can be raised via the menu entry Help/ConfigEditor log level.
Level 4 can be helpful since with it, the service calls are logged. With luck, level 5 offers a detailled view of actions.
Since version 4.0.7.6.12 the logfiles are deposed by default in the user home directory. In Windows the folder
c:\Users\[User name]\AppData\Roaming\opsi.org\log
In Linux the default logfiles folder is the (hidden) subfolder ".configed" in the user home directory.
The current logfile is named configed.log, the up to 3 preceding versions are configed_0.log, configed_1.log, configed_2.log.
The logging directory can be changed via the command line option "-d".
The current logfile path is displayed at the Help menu, entry "Current logfile". The filename can there be retrieved in order to use it in an open file dialog of a viewer program or can be directly opened by the default application for .log files.
4.1.2. Choosing the language
The opsi-configed tries to use the language following the OS defined locale. If the matching translation file is missing English is used as default language. If terms in translations file are missing the expressions of the Englisch translation are used as default.
When calling the opsi-configed you can set a locale via the command line option
-l resp. --locale
On principle, the locale has the format language_region, each component with two characters, eg. en_US of de_DE. It suffices to give the two character language code since there no region specific variants prepared.
In a running opsi-configed the language can be switched via the menu item File/International. A change triggers a re-initialization of the program with a (nearly complete) rebuilding of the visual components in the new language.
Finally the call parameter
--localizationfile
can be used for directly prescribing a localiziation file. The additional parameter
--localizationstrings
has the effect that the display of the localized expressions is combined with displaying the terms for which expressions should be given. This can be used for producing and testing a localization file.
4.1.3. Logging of the opsi-configed
By default, the opsi-configed uses its log level 3 "Info". The level can be raised to 4 "check" or 5 "debug".
To change the log level the command line option --loglevel [LEVEL] can be used. It is not recommended to set level 5 if not already the start process has problems since, with level 5, the produced log file is very large; it is difficult to view. When the opsi-configed is running and a potential error situation is expected the log level can be raised via the menu entry Help/ConfigEditor log level.
Level 4 can be helpful since with it, the service calls are logged. Level 5 often offers a detailled view of actions.
By default the logfiles are deposed in the user home directory in the subfolder ".configed". The current logfile is named configed.log, the up to 3 preceding versions are configed_0.log, configed_1.log, configed_2.log.
In newer versions of windows the user home directory is interpreted as
c:\users\[USERNAME]\appdata\local
Observe that the Windows Explorer shows a localized version of "users" and does not give "AppData" in the listing of "c:\users\[USERNAME]". But the AppData folder contents appear, when "appdata" is supplemented to its superfolder name.
The logging directory can be changed via the command line option "-d". The opsi product opsi-configed uses this option to set the logging directory to
c:\opsi.org\log
But only local administrators can write to this location. If other users start the opsi-configed the location
c:\users\[USERNAME]\appdata\local
will therefore again be used.
4.2. Login
The opsi-configed tries to connect to the opsi server via https. The login is done with the given parameters opsi server[:Port] (default port 4447 – opsiconfd) and the user/password pair of the opsi-config-server account. For a successful login the provided user has to be a member of the unix group opsiadmin.
In the local user profile, the opsi-configed saves certain session info in order to rebuild the essential working context after a restart, in particular a selected client group. Since version 4.0.7 the session data is used to produce a selection list of opsi servers to which you were connected (e.g. a productive one and a second one for experimental purposes). The last server used gets the highest place, and can be directly used again.
The gzip compression in HTTP protocol reduces the amount of data being transferred at the expense of an extended processing time, this is due to the fact that the data must be compressed and uncompressed. It has been observed that the reaction times tend to be shorter without compression in the local network, as the effects normally surpass the prolonged processing time. For transmissions over the WAN, it tends to be the opposite. In the practice, little difference is noticed on LAN connections, but relevant differences are noticed on WAN connections, so the Gzip option is enabled by default.
The feature check which clients are reachable runs in the background and shows the results in the client table. It can be enabled from the login screen mask or via command line parameter. The default refresh interval is 0 min (= deactivated). It should be observed though that a too short refresh interval produces a lot of network waiting states which can slow down the opsi server.
4.3. Copy & Paste, Drag & Drop
You may copy the selected entries from nearly every section of the opsi-configed to the clipboard using the standard key combinations (Ctrl-Insert, Ctrl-C). This may be used to transfer interesting data to other programs.
For most of the tables you may also use Drag & Drop to copy the data e.g. to Excel or a
4.4. opsi-configed modes Client configuration / server configuration / license management
To switch between the different usage modes of the opsi-configed, use the buttons in the upper right corner of the opsi-configed frame. Since version 4.0.4, there are six buttons.
The first three buttons allow you to change the editing target of the main window: client configuration, server configuration. On the other hand, each of the buttons group actions, product actions and license management starts a special window to manage the specific objects or actions.
These windows can as well be opened via the main menu item windows (since opsi-configed version 4.0.7).
4.5. Depot selection
All opsi-depotservers that are integrated with your server, are listed in the upper left corner of the opsi-configed. By default the depot on your opsi-config-server is selected and the clients belonging to this opsi-depot are shown.
You can select multiple Depots at the same time and edit their clients together. However, only the selected depots are synchronized with each other. Trying to edit clients from asynchronous depots together will be rejected with an appropriate warning and the corresponding error message.
As of version 4.0.5, there is no need to carry out a complete data-reload when switching to a different depot-server, that means, when you select a depot its data is loaded immediately. In addition, there are the following buttons:
-
(=+) : Marks all depots with identical product stocks.
-
(++) : Marks all depots (you can also use Ctrl-a)
4.6. Cient selection
After a successful login, the main window pops up and shows the tab Client selection. This tab shows a list of known clients from the selected opsi-depot resp. the clients which are selected using the tree view control on the left side of the opsi-configed.
Since version 4.0.4, the opsi-configed saves on the local machine, for the current user, the current depot server and group selection. If the opsi-configed is restarted, you can continue working at the point where you were.
Please note, that group selection is preserved when changing depot selection. In order to see all clients in the other depot the group selection has to be changed appropriately. the same pattern of work.
You may select a line of the list not only by manual scrolling and selecting but also by a String search. This requires that you enter a String into the search field at the top of the list
How the search works is determined by the selected elements in two drop down lists:
Via field selection you can choose if
-
all fields (more precisely, all fields that are for this temporary configuration represented as columns) are searched (default), or
-
only one field (and which one) is searched.
Concerning the method of search you may select between the options (since 4.0.7):
-
Full-text: the search string is used in a similar way to a web search on a certain search engine for example in the standard manner; i.e., if the input contains several keywords (delimited by blanks) then the word elements will be a match if any of the input parts are fully contained in some of the columns.
-
Full-text (complete string): the search string is used like using a web search on a search engine the search string embraced by citation marks; i.e. a table line will match if the complete input string is part of one of the columns content.
-
Start-text search: a table line will be a match if the column text starts with the search string.
-
Regular expression: the search string is interpreted as a so called regular expression; i.e., a line will be a match if the input string produces a match according to the rules of regular expressions (as described in the java doc for java.util.regex.Pattern).
The enter key produces the next search hit. If there is no match it advances the mark to next line.
More selection functions based on String search are shown in the context menu of the search field.

Examples of Search Patterns
All PCs which have a name or a description containing the character sequence Miller with capital M or with m are found by using the pattern .*iller.* The dot in " .* " means "arbitrary character", the asterisk " * " means "arbitrary number of occurrences (of the beforehand designated element)". That is .*iller.* it matches, if anything (any number of any characters) come before iller and anything after iller. Since "any number" may be zero Home of Miller matches where no character follows after iller. But to ensure that we do not mark Tiller as correct a more precise pattern would be .*[Mm]iller.* Several characters enclosed in brackets are interpreted as the searched value must contain one of the enumerated characters. With this more precise pattern, every string is recognized which contains either Miller oder miller but no other string. Here is yet another example, a pattern search for products: 0.-opsi.*standard matches for all products which have a name beginning with "0", followed by an arbitrary character, followed by -opsi, followed by arbitrary characters (in arbitrary number); finished by standard. To ensure that the second character is a number symbol, i. e. one of the characters "0", "1", "2", "3", "4", "5" , "6", "7", "8", "9", one can write 0[0123456789]-opsi.*standard As short hand for [0123456789] one can use, since it is a complete partial sequence of the sequence of all characters, [0-9]. Therefore the search pattern reduces to 0[0-9]-opsi.*standard Matching products e.g. 03-opsi-abo-standard or 05_opsi-linux_standard More informations on the topic can be found in the java api doc, key word "java.util.regex.Pattern". |
4.6.1. The clients list
The clients list has per default the columns client name, description, on, IP address and last seen.
-
client name is the full qualified hostname which is the client name including the domain name
-
description is a free selectable description which you can edit in the top right hand side of the window
-
On shows after clicking the button Check which clients are connected the result of this query. This feature runs in the background and shows the results in the client table. It can be enabled from the login screen mask or via command line parameter. The default refresh interval is 0 min (= deactivated).
-
IP address shows the IP number to which the opsi server resolves the client name.
-
last seen shows the date and a time of the last client connect to the opsiconfd web service
Some columns are deactivated by default:
-
session infos (data is retrieved from the operating system running on the specific client)
-
Inventory No (displaying some optionally entered data)
-
created (date and time of client creation)
-
opsi mac address (hardware address of the client as used by opsi)
You may activate these columns using the context menu. The configuration of the columns being displayed may be changed using the entry configed.host_displayfields in the server configuration.
Adding the column session infos enables the button "request session infos from all clients" in the button panel.
When this button is clicked the opsiconfd tries to connect to all clients and to retrieve data of the active user sessions. From the result, the account names are shown in the column session infos. Instead of using the button you may start the request only for the selected clients via the context menu or the main menu entry OpsiClient. By doing this, network timeouts are avoided.
Since the search function for the client list works (if not configured otherwise) on all displayed columns you may now find out which is the client belonging to a logged in user (with known account name).
To sort the clients by a certain column click on the top header of that column.
4.6.2. Selecting clients
You can select one or multiple clients to work with. The client view can be restricted to the selected clients by clicking the funnel icon or from the menu by Grouping / Show only selected clients.
A selected client group can be saved with the icon Save grouping or from the menu by Grouping / save group with a free selectable name.
You can use the mouse to add the selected clients to an existing group (by dragging them to an existing group which is displayed in the tree view).
In the client selection dialog (as called via menu Selection / Define search) clients can be selected using a variety of criteria based on their configurations.
E.g., it is possible to search for opsi installed products as well as software found by the opsi software audit. You may as well search for PCs satisfying certain hardware conditions. Criteria may be combined by logical AND or OR operations and may be negated by a NOT (which is produced by a click on the Not-Field before the property field). Search strings can be given as fixed strings combined with asterisks * as wildcard symbols.
Search definitions can be saved and then again used via the menu item Selection/Use saved search definition.
It is also possible to run a saved search from the command line when the opsi-configed editor is started. By including the flag "-qs" and the name of the saved search, the configuration editor will start with the saved search results. If the name is omitted, then a list of available searches will be displayed.
To detect failed installations, the menu item Selection offers Failures with product and Failures occurred (today, since yesterday, …), since version 4.0.5 .
Choose the first setting to get a list of all products. If you select a single product, all clients will be shown, where the installation of this product failed.
When choosing for instance Failures occured - today, all the clients will be marked, where an product installation failed today.
4.7. Client selection and hierarchical groups using the tree view
Clients can be grouped in a convenient way by using the tree view control placed on the left side of opsi-configed frame.
4.7.1. Basic concepts
The tree view control has three base nodes groups, directory and client list. Alls clients of the selected depots are displayed in the group client list.
The nodes groups and directory are different in so far as each client can have any number of locations in the groups subtree but has a unique location in the directory subtree; as long as there was no other assignment to subgroup of directory a client is automatically placed into the group NOT_ASSIGNED.
If you select a client, all groups to which the client belongs will get color marked icons.
4.7.2. How to …
By a click one a node (or a group) all clients beyond this node will be shown in the Clients tab, but none of these clients is selected for processing.
By a click one a client, this client will be shown in the Clients tab and selected for processing. You may also use this way to change the selected client while you are in a other tab like product configuration without coming back to the clients tab.
You may use Ctrl-click and Shift-click to select multiple clients. This tree view control show the groups which are created according the chapter
You may also create groups by using the context menu above ALL or any existing group.
You will be asked for the new groups name.
A group can be populated with clients using Drag&Drop by
-
copying clients from the Clients tab to the group in the tree view (left mouse button)
-
copying clients from the tree view control below the node ALL to group in the tree view (left mouse button)
-
moving clients from a group in the tree view control to a other group in the tree view (left mouse button)
-
copying clients from a group in the tree view control to a other group in the tree view (Ctrl-left mouse button)
A group can
-
be moved to a different location via drag & drop.
The context menu of a group item can be used
-
to create a subgroup;
-
to edit the group properties;
-
to delete the group together with its subgroups and all client assignments of them;
-
to remove all client assignments while keeping the group and its subgroups;
-
to display the the contained clients and select them in one step.
4.8. Client processing / Client actions
Using the menu OpsiClient or the context menu in the Clients tab you may choose from a lot of client specific operations
4.8.1. Install By Shutdown, Uefi Boot and WAN Configuration
Several client standard configurations can be applied directly in the client information panel which is located on the right side of the clients page. Please observe that UEFI support and WAN configuration both are currently based on non free extension modules. If these modules are not active the corresponding buttons are disabled.
-
Install By Shutdown:
In Section 9.19, “opsi Installation on Shutdown (free)” , the method do switch to Install by Shutdown installation is described en detail. You can automatically trigger this configuration by pushing the On-Button for InstallByShutdown. Observe that this requires a opsi-client-agent reinstall or reconfigure. Alas, the state of the configuration can currently only be seen in the product property `on_shutdown_install`of the opsi-client-agent product. -
Uefi Boot:
The state of checkbox Uefi Boot indicates, if a client is configured for UEFI boot. It is activated the value of the client host parameterclientconfig.dhcpd.filenameis changed tolinux/pxelinux.cfg/elilo.efigeändert. (For more infos cf Section 9.6, “opsi with UEFI / GPT”) -
WAN configuration:
The opsi configed checks, if the standard Wan configuration is available or not. The check mark for the WAN configuration will be set or not accordingly. If you check the box manually, the default configuration will be set.
This configuration is no longer hard coded since version 4.0.7.6.5, but is read from the server host parameters configed.meta_config.wan_mode_off* and is also interpreted as a negation. If you have kept the automatically set Meta_Config.wan_mode* parameters, the one described in Section 9.11.5, “Recommended configuration when using the WAN/VPN extension module”, can be taken as an example or recommendation for a standard WAN configuration given by uib gmbh.
| Whether the client is configured as a WAN client or perform an UEFI boot, can also be displayed in the appropriate columns on the client table. For the current session you can find on the menu item OpsiClient or activated in the context menu, permanently via the entry configed.host_displayfields for the server host parameters. This can be seen directly in the overview, for which clients the property is set, and it can also be searched for and sorted out. |
4.8.2. WakeOnLan (Wake selected clients)
Choosing this menu entry, you will send the selected clients a WakeOnLan signal.
Since version 4.0.7 you can choose
-
if the network signal is meant to be sent to the selected clients at once
-
which delay should be between the waking of two clients
-
when the process shall start (via a scheduler).
If a client is assigned to a depot server which is not the configserver then the Wake On Lan signal is not directly sent to the client, but the opsi-configed tries to establish a HTTPS connection to the opsiconfd of the depot server which in turn sends the Wake On Lan package to the client inside its network segment.
It should be observed that it is the opsi-configed which triggers the actions, therefore the program must not be shut down in the meantime.
4.8.3. Fire opsiclientd event (Push Installation)
This menu entry is used to send to the opsi-client-agent on the selected clients a command to fire the event which is selected in the submenu. The standard event is "on demand" which means the demanded action is started at once. Be aware that this may have the effect that the client is rebooting without any warning.
To incorporate additional events (which should be configured in the opsiclientd.conf) into the submenu you have to edit the config configed.opsiclientd_events via the tab (server) host parameters.
All messages will be shown on the active desktop. If the client isn’t reachable, you will get a message.
What happens exactly if you fire the event on_demand can be configured in the event on_demand configuration.
4.8.4. Sending messages (Show popup message)
Choosing the menu entry Show popup message you will get a small edit window where you can type in your message.
By clicking on the red tick you will send the message to the selected clients.
At the selected clients a message window will appear.
4.8.5. Session info for selected clients
The selected clients get the signal to communicte their session information. The data is shown in the session info column (if visible).
4.8.6. For WAN-Clients: Delete package cache
On WAN clients there are occasional problems with the package cache synchronization. This function resets the cache.
4.8.7. Call external remote control tools for selected clients
The option Remote Control Software call in the client context menu as well as the client main menu (since opsi-configed version 4.0.1.11) is very powerful. It can be used to use any command that the operating system offers, parametrized e.g. by the client name.
As an example there are configurations automatically generated which can be used to send a ping to the selected client: one
ping command that works in Windows environment and one command that requires a Linux X environment. Please observe:
opsi-configed calls obviously the command in its environment, i.e., we need the Linux command when the opsi-configed
is running in Linux.
The selection window has three parts. The upper part lists the names of the existing commands. It follows a line, which shows the selected command and offers the chance to edit it (if this is allowed). Additionally, the line contains the buttons to execute or abandon the action. The third text area of the window captures any messages that are returned by the operating system when calling the command.
These calls offer a quasi infinite range of opportunities. For example, a command can be configured to open a Remote Desktop connection to the selected client (if it allows such connections). On a Windows system, such a command is
cmd.exe /c start mstsc /v:%host%
In a Linux environment the following command can be used:
rdesktop -a 16 %host%
In these examples serves %host% as a variable, which opsi-configed automatically replaces
by the value for the selected host. Other variables that can be analogously used in the commands are:
-
%ipaddress% -
%hardwareaddress% -
%opsihostkey% -
%inventorynumber% -
%depotid% -
%configserverid%
If the command is marked by the additional server configuration entry editable as true,
then the command line allows ad hoc editing. For example, you may supply a requested password or vary
the command as needed.
| If there is some command declared as editable then in fact any program addressed at the client computer can be called by changing the editable command. |
If more than one client is selected the command will be executed in a own thread for each client.
The list of remote control commands is editable via server configuration entries (cf. Section 4.16, “Host parameters in client and server configuration”).
To define a command example, at minimum an entry configed.remote_control.example
(or configed.remote_control.example.command) must be generated. The value of property has to be the command
(in which the variables %host%, %ipaddress% etc. can be used). Additionally, an entry configed.remote_control.example.description
can be defined. The value of this entry will be shown as tooltip (if not existing, the command itself will serve as tooltip content).
Furthermore, a Boolean entry configed.remote_control.example.editable can be added. If its value is set to false the command
cannot be edited in the selection window.
4.8.8. Shutdown / reboot of selected clients
You may send the selected clients a shutdown or reboot signal. You have to confirm this command at the opsi-configed.
| If the client received the signal, it will going down with out any more questions. |
4.8.9. Delete, create, rename and move clients
You may delete the selected clients from the opsi-server.
If you choose to create a client, an input mask opens. There you enter or confirm the required data – client name without domain specification, domain name, depot server name. You may add a textual description for this client and notes on this client.
The mask also contains fields for an optional declaration of the IP-number and the ethernet (MAC) address of a client. If the backend is activated for the configuration of a local dhcp-server (which is not the default setting), this information will be used to make the new client known to the dhcp-server. Otherwise the MAC address will be saved in the backend and the IP-number will be discarded.
When creating clients you can directly for the new client specify to which group it should belong, as well as which netboot product should be directly set on setup. In addition, you can activate directly the Install by shutdown, UEFI Boot and the (standard) WAN configuration from the beginning. These settings can easily be made in the Hosts-List. These configurations are only available since the version 4.0.5.8.1 .
Since opsi 4.0.4 it is possible to disable the options for creation and deletion of an opsi client. This is used if the client creation should be managed by a different service, eg. the UCS service.
For the configuration of these options, a host parameter (config) is provided. It is named configed.host_actions_disabled and
offers the list values
-
add client -
remove client
(multiple selection allowed). The default is the empty selection meaning that no option is disabled.
The default setting can be changed so that adding and removing clients from the opsi-configed is disabled:
opsi-admin -d method config_createUnicode "configed.host_actions_disabled" "Disable host actions" ["add client","remove client"] ["add client","remove client"] false trueYou may rename a selected client, you will be asked for the new name.
Moving a client to a different depot-server. If clicked the following windows appears with a list of existing depot-servers
4.9. Product configuration
Switching to the tab Product configuration you get a list of available software packages with its installation status and action status for the selected clients.
Since opsi 4.0.4 a search function is added.
With the search function, products can be searched by product names and (if desired) in combination with special values in the fields of the product table (like searching the client table). Therefore a search string can be entered. The search starts immediately and the first matching line is marked . If there is no match to be found (or characters are removed from the search string), the first line of the table is marked.
The context menu offers some more options.
To get a better overview, activating the filter function reduces the product view to the selected products only. The selections stays active until the filter is disabled by clicking the filter button again.
If there is a different status for the selected clients this will be marked grey (undefined). The list of the selected clients is shown at right on top.
You can also sort the product list by clicking at the column header.
This are the columns:
-
Status is the last announced state of the product and can hold the values installed, not_installed, unknown. The table shows an empty cell if the value is not_installed to improve the usability of the view. The cell becomes grey if a multitude of selected clients is selected and does not share a common value (grey coloring represents the pseudo value mixed).
-
Report informs about the progress or the result of the last action using the pattern <action result> (<last action>). During an installation process there may be indicated installing, afterward e. g. failed(setup) or success (uninstall).
-
The column Requested action holds the information which action is to be executed. Possible values are none (shown by an empty cell) and the action types for which scripts are defined in the product package (possible values are setup, uninstall, update, once, always, custom).
-
The field Version displays the software version number combined with the opsi package number of the software package installed on the client.
There are two more columns which can be activated via the context menu:
-
Priority class displays a priority value that is assigned to the product (highest priority +100, lowest priority -100). It influences the product order when products are installed (by virtue of the product_sort_algorithm)
-
The position column displays the product ordering forecast for installation sequences.
Choose a software product to get more product information in the right part of the window like:
-
Complete product name: full product name of that software package.
-
Software/package version: software version-version of the opsi package of the software package (specified in the opsi installation package).
-
Product description: free text to describe the software.
-
Hints: free text with advices and caveats for handling the package.
-
Requirements: A list of other products which the selected product (say A) depends on combined with the type of dependency: required means that A requires the other product (B), but it doesn’t matter whether B is installed before or after A. pre-required means B has to be installed before A. post-required means B needs to be installed A.
-
Configuration for client: It is possible to define additional properties for a product. Their values can be evaluated in a setup script to configure the product per client. Because of the intrinsic complexity of a property definition there is a specific GUI element for displaying and editing the table of properties:
4.10. Property tables with list editor windows
A property table is a two-column table. In each row, the first column contains a property name, the second column displays the assigned property value(s).
It may be configured that a tool tip is displayed showing some information on the meaning of the property and the default value.
If you click at a value a window pops up: the list editor for this property. It shows a value resp. a list of preconfigured values with the current value (resp. a combination of values) as selected.
Clicking a new value changes the selection.
If the property value list is editable (new values may be added to the existing list resp. existing values changed) the window comes up with an edit field for the new or modified values.
The most comfortable way to get a new value that is a variant of an existing one is double clicking the existing value in the list. This copies it into the edit field where it can be modified.
As soon as the edit field contains a new value – not yet occurring in the value list – the plus button will be activated with it the new value can be added to the list of values.
If multiple values are allowed – as it should be e.g. for the property additional drivers – a value may be added to the set of selected values by Ctrl-Click . The very same action removes a selected value from the set. The minus button empties the selection set completely.
When the list has been edited the green check mark turns to red as usual in the opsi-configed. Clicking it takes the new selection as new property value (and finishes editing). Clicking the blue cancel button stops editing and resets the original value.
4.10.1. Hidden Password Property Values
A property value that is a password should not be directly displayed.
Until this feature will be constructed as a special value type in some coming release the hack is used that a property value will only be displayed if the user explicitly requests it in cases (since version 4.0.7 ):
-
the property key text contains the string password
-
the property key text starts with the string secret
E.g., the value of the property root_password in the Linux netboot products is displayed as a sequence of stars (until the user does the edit click and explicitly confirms to showing the password).
4.11. Netboot products
The products on tab Netboot products are mainly used to install the client OS (operating system) and are listed and configured like the products on tab Product configuration.
If for the selected client(s) a netboot product is set to setup, the correspondent bootimage will be loaded and executed at the next client reboot.
This is usually done to initiate an OS installation or any other bootimage task (like a memory test etc.)
4.12. Hardware information
With this tab you get the last detected hardware information for this client (only available if a single client is selected).
4.12.1. Automatic driver upload
To simplify and automate the drivers of special clients and to upload them on the {opsi-depot-server}, since version 4.0.5, the option to select the paths from the hardware information is possible, thus the opsi-configed via the Share delivers the above mentioned. The two offered byAudit driver paths are composed of the manufacturer and the product or the model, which are respectively read from the computer and the mainboard. By clicking the right button to upload a driver, a new window will be displayed to add more settings.
If you open the opsi-configed on a Linux system, it is not directly possible to carry out a driver upload because the connection is carried out via a Share. This needs to be made manually. However, the methods or directory structures are an essential aspect of the drivers integration for linux users as well as for windows users.
Without further settings, the driver upload of a Windows computer, works only if the connection to the Share is enabled.
Among other things, information must be given in a new window, like to which Windows product should the driver be prepared, which drivers are to be uploaded and with which method or the directory in which the driver integration takes place. The target directory is accordingly changed with the selection of another method. The previously selected byAudit driver path can be found again by default in the selected method byAudit, that specifically integrates the selected driver for the type of machine.
Following methods and directories are possible:
-
standard: For the drivers which are found in
./drivers/drivers/, the driver will be matched to the corresponding hardware using the PCI IDs (i.e. USB- or HD_Audio-ID) in the description file, and then integrated into the Windows setup as needed. It may be the case that the drivers found by opsi in this location do not necessarily work with your hardware. For the drivers which are found in./drivers/drivers/, the driver will be matched to the corresponding hardware using the PCI IDs (i.e. USB- or HD_Audio-ID) in the description file, and then integrated into the Windows setup as needed. This is the fall back directory for all clients. -
preferred: In the case that you have to support special hardware, and you can find the additional drivers from the manufacturers, then use the following procedure to include them in the installation. Place the additional drivers in their own directory under:
./drivers/drivers/preferred(the naming and depth of the directory structure is not important). Drivers that are found in the directory./drivers/drivers/preferredwill be integrated into the Windows setup, assuming that opsi finds a suitable match to the drive hardware based off of the PCI IDs (i.e. USB or HD_Audo-ID) in the description file. Problems can occur when the same PCI ID of the drivers is found inpreferred. In this case, a direct mapping of the drivers to the devices is needed. -
excluded: It could happen that the manufacturers include different drivers for different operating systems (i.e. Vista vs. Win7) or different configurations (ie. SATA vs. SATA RAID). The
create_driver_links.pycannot make this distinction. If you think the wrong driver has been installed, then move the driver to the drivers/exclude directory and then callcreate_driver_links.pyagain. Drivers in the directory drivers/exclude are not used during the integration. -
additional: When installing additional drivers based on the PCI-IDs or USB-IDs, they should be installed under the directory
./drivers/drivers/additional(where name and depth of the directory structure is not important). You can map one or more drivers to a client using the Product-Property additional_drivers and a list of driver directories under./drivers/drivers/additional. The directories specified by additional_drivers are searched recursively until all drivers are found. This method can be used to make a specific directory based on the client type (i.e. dell-optiplex-815). -
byAudit: The previously described mechanisms that directly map drivers to devices is automated since the 4.0.2 Release 2 of opsi. Opsi will search the directory
./drivers/drivers/additional/byAuditfor a director name that matches the field Vendor that was given in the Hardware Inventory. This Vendor directory will be search for a Model directory that corresponds to what is seen in Hardware Inventory. If this directory is found, then it will be manually assigned to the product property additional_drivers. The directory name byAudit is case sensitive. The directory names for Vendor and Model are not case sensitive (Dell and dELL are treated the same way).
Some manufacturers use model names that are very delicate to this method, since some special characters such as / are not allowed to be used in files or directory names. An example for a model name could be: "5000/6000/7000". A directory with this name is not allowed because of the special characters. Since the third Service Release from opsi 4.0.3 the following special characters: < > ? " : | \ / * were replaced internally with an underscore "_" character. With this change can the above example be replaced with: "5000_6000_7000" the directory will automatically be shown, even though the directory structure information in the hardware inventory is not visually the same.
After uploading a driver to ./drivers/drivers or ./drivers/drivers/preferred the script create_driver_links.py should be executed on the opsi-depot-server!
|
4.13. Software inventory
With this tab you get the last known software information for this client (only available if a single client is selected).
4.14. Logfiles: Logs from client and server
The client specific log files are stored on the server and visible with the opsi-configed via the Tab log files.
The level up to which the log lines are seen can be chosen by a slider (wheel mouse enabled), so that errors can be easily found.
It’s also possible to search in the log file (to continue the search press F3 or Ctrl-L = last search repeated).
4.15. Product default properties
To change the default values of the products for one or more opsi-depots, there is a tab, called Product default-properties.
This is only available if you select Properties of depots (which is the second button at the top right hand side).
In the main table, all products are listed with the product version as well as the package version.
If a product is selected, at the top of the right side (as is customary for the client product configuration) general information about the product packages is shown. Below is the list of all depots, that have installed the selected product. The table below with the property keys and values is also known from the client product configuration.
You can select a single depot or multiple depots to change the default values
(which are also called the depot values) of the product.
As the default, all available depots are preselected. With the usual shortcuts
(Ctrl-a, Ctrl-Click or Shift-Click) multiple or all clients can be selected.
If the property value is shown grayed (see Figure 38, “opsi-configed: product default properties” - “gui_language”),
the values for that property differ on the selected depots.
On the right side of the depots are three buttons:
-
(=+): Mark all depots that have identical values
All depots, that have the same default values, are marked. -
(++): All depots are marked.
-
(globe): set the package default values
The original package default values of the products will be set for the selected depot(s).
4.16. Host parameters in client and server configuration
There are many configuration options for the opsi server and the opsi clients that may be set or changed via the tab Host parameters. Server defaults are set in the mode server configuration, client specific values in the mode client configuration plus manual selection of the Host parameters tab (see also Section 4.4, “opsi-configed modes Client configuration / server configuration / license management”).
On principle, these configuration entries (config objects of the opsi-server) are conceived as lists of values. Therefore they are edited via the list editor component (cf. Section 4.10, “Property tables with list editor windows”).
Depending on the specific type of a configuration object,
-
the elements of the list can be of type text (
Unicode) or of typeBoolean(i.e.true/false); -
the set of all values from which elements can be selected may be fixed or extensible.
-
the object has a defaultValues-entry, which comprises in the singleValue case exactly one list element, in the multiValue case some partial list selected from the list of all possible values.
New configuration objects can be created via the context menu of the server host parameters. At this place it is also possible to remove existing entries.
The relationship of server and client entries is a little bit complicated.
-
Server entries hold the defaults for client entries (this is the defaultValues entry in the server configuration object)
-
Consequentliy, if a client entry is needed a server configuration object must be created beforehand.
-
And, when a server entry (a config object) is deleted, the depending client entries (called config states) are (automatically) deleted as well.
-
If the client related value is shown as identical with its (server based) default value this may be be because there does not exist a client specific data base entry or because the client value is identical with the server default value. In the first case the client value changes when the server default value gets new contents, in the second case the client remains unchanged.
-
In order to work comfortable with this situation since opsi-configed version 4.0.7.6.5 the context menus of the client host properties offer the options (1) to remove the specific client values, so that from now on only the current server values are decisive, (2) to fix the specific client values to the current server values.
-
if the currently presented client value iis not identical with the server default value it is given in a bold font.
-
There are configurations objects for which client values can be created and edited but in fact only the server objects are used. In most cases, the current configed does not show them any more in the client parameters view.
To get more structure the configurations objects are categorized in some (predefined) groups. The groups are listed in a tree-like manner on the left part of the panel. The entry name/value pairs belonging to the selected group are shown in the right part of the panel. Wheel mouse scrolling is enabled as well on the left as on the right side.
4.16.1. Management of user rights and roles
Starting with version 4.0.7.5 the opsi-configed includes the user roles function.
| In order to use this feature the module user roles must be activated in the modules_-file. |
In the interface, in the overview of the server host parameters, the category user shows the availability of the function (not necessarily active). The user branch of the properties tree starts with a boolean entry
user.{}.registerwith default value false.
The other entries at this location represent the default values for the user-specific configurations of the server console (cf. Section 4.20, “Server-Console”).
To activate the user role extension you need to:
-
Set the value of user. {}.register to true.
-
Load a modules file that has the userroles extension temporarily or permanently activated.
When the user-role extension is activated, an entry is created in the properties tree for the logged-in user. The default settings used for the administration of rights are like the "classic" requirements for an administrator, that means, that this user has no restriction whatsoever. E.g., for a user named admindepot1 the following entries are generated:
user.{admindepot1}.privilege.host.all.registered_readonly [false]
user.{admindepot1}.privilege.host.depotaccess.configured [false]
user.{admindepot1}.privilege.host.depotaccess.depots []
user.{admindepot1}.privilege.host.opsiserver.write [true]These four items mean:
-
admindepot1 is not restricted to read-only access to the server (a pure read-only access might be appropriate for a help desk staff member);
-
depot restrictions do not exist or are not taken into account;
-
consequently, the list of depots available to the user can stay empty (and if some depots are entered, this has no effect);
-
the user is allowed to edit config server settings of all kinds.
In the case that the access of admindepot1 is to be restricted to the computers in the depot server depot1, the following should be set:
-
host.depotaccess.configured is to be set to true;
-
the value "depot1" is to be put into the list host.depotaccess.depots.
After a complete data reload, clients from other depots are not more visible to admindepot1 (and also only the depot settings for depot1 are accessible).
| admindepot1 him/herself can change this settings as long as she/he owns the privilege host.opsiserver.write |
In order to complete the restriction, it therefore is required to set
-
host.opsiserver.write to false.
| The privileges which are set in this way restrict only the functionality of the opsi-configed. Until further notice, they have no effect if the JSON-RPC interface of the opsi-server is accessed by other means. |
4.17. Depot configuration
In the mode Properties of depots you will see the tab Depots. There is a drop down menu to select the depot. After selecting the depot you may change the properties of the opsi-depot.
see also:
4.18. Group actions
The button "group actions" in the main button bar (cf. Section 4.4, “opsi-configed modes Client configuration / server configuration / license management”) opens a window for group related functions.
At the moment, it provides only one function which is relevant for the opsi-localimage module.
-
to search for an operating system, that had been installed on all of the clients of the selected group and therefore can be offered for all of the clients of that group.
4.19. Product actions
The button "product actions" in the main button bar (cf. Section 4.4, “opsi-configed modes Client configuration / server configuration / license management”) opens a window for functions related to products resp. packages.
Currently it offers two options:
-
An .opsi file (opsi package) can be selected or entered and can be uploaded to the opsi server; the default upload directory on the server is the network (samba) share named opsi_workbench. The button click starts installing the package on the server, like invoking the opsi-package-manager.
-
The WinPE files and install files for an Windows product (Windows Vista and above) can be uploaded to the server product directory (share opsi_depot), so that windows products do not have to be managed from the server side.
4.20. Server-Console
| Some of the following features require at least python-opsi version 4.0.7.38, in particular defining you own commands as described in Section 4.21, “Define commands” and using them via configed. |
With version 4.0.7.5, the configed is extended with a new main menu entry, the "Server Console". At this place some options are bundled to access the opsi-server via a SSH-Connection. It is as well possible to start a terminal as well as menu items are offered of some predefined commands on the opsi-server.
4.20.1. Connection data and permissions
If not otherwise configured, it is tried to build a SSH connection with the same user/server pair for which to configed login was done.
Should this not be the case the connection can be also started via a SSH key (possibly with a password) when the configed starts. In this case, the following start parameters can be used:
-
--ssh-key PATH: e.g. --ssh-key /home/user/.ssh/id_rsa
-
--ssh-passphrase PASSPHRASE: e.g. --ssh-passphrase Password
The settings can be changed or adjust under the menu entry "Connection Information".
The visibility of menu items in the server console menu is controlled by a series of server host parameters in the user section. If the user roles feature is used (cf. Section 4.16.1, “Management of user rights and roles”) the configs are specifically set for each user (the default values for a newly created user entry are taken from the top user level).
In order to be able to use different functions, the appropriate server settings must be activated.
-
user.{}.ssh.serverconfiguration.active:
Activates the ssh connection settings menu. (Default: false) -
user.{}.ssh.commandmanagement.active:
Activates the editing of commands and their menu entries. (Default: false) -
user.{}.ssh.menu_serverconsole.active:
Deactivate the "Server Console" menu in principal. (Default: true) -
user.{}.ssh.terminal.active:
Allows the usage of the ssh shell. (Default: true) -
user.{}.ssh.commands.active:
Allows to execute all menu items displaying stored commands. (Default: true)
4.20.2. SSH-Terminal
With the Terminal, Linux commands can be run from the connected SSH-Server.
In addition to the possibility to replace the input with asterisks (*), which is strongly recommended for the input of passwords, a process can also be canceled by clicking the "End process / connection" button or by pressing "Ctrl + C".
Just like in the Terminal, the "TAB" can be used to complete commands. Warning: Paths will not be completed - only Linux system commands.
Besides it is also possible to specify data sources, that before the execution can be replaced by concrete data. More about this functionality:
Section 4.21, “Define commands” - Item: Datasources)
4.20.3. Predefined commands with input masks
Under the menu group "opsi" a few commands are available independently of the self-defined commands with their own input interface. These simplify the handling of various scripts.
-
Download from data …
Any data file which can be downloaded from the Internet can also be downloaded by the "wget"-command and stored in a certain path on the Server. This could be used for example to download opsi-packages from download.uib.de -
Create opsi product file …
Prerequisite for this command is an opsi-utils package with version >= 4.0.7.7. Using this menu item, an opsi package can be created, specifying the directory upon which must be stored. In addition, can the found versions (package and product version) be displayed and overwritten with a button. And also, a md5sum and/or a zsync file can be created. -
Set opsi-rights …
This menu item maps the opsi command opsi-set-rights. After entering a specific (optional) path in which the script is to be executed, the root password is prompted and the script is executed in a separate window. -
Package-Installation …
With this command, opsi packages can be installed on all depots or in one depot using "opsi-package-manager". You can also specify the server path to the package where the opsi package is located.
By selecting a package from the Internet, the functionality of "File download …" command is taken up and then the downloaded package is installed on the depot. Additionally, the parameters "--update" and "--setup" of the opsi-package-manager are implemented. If the zsync and md5 files of an opsi package are to be downloaded, the switch "zsync and md5 include" can be activated. Then the url of the packages is added accordingly and the additional files are also obtained.
You can find more about opsi-package-manager under Section 5.3.2, “Tool: opsi-package-manager: (un-)install opsi-packages”
-
Package-Deinstallation …
From a list of installed packages one can be selected and uninstalled.
Please check Section 5.3.2, “Tool: opsi-package-manager: (un-)install opsi-packages” -
Deployment opsi-client-agent …
If you want to add existing computers to opsi, the opsi-client-agent must be installed on the target computer. If you select the clients in the configed and execute this command, the client names are copied into the corresponding field. If the command is to be executed on several clients in a single call, the login data must be the same on all the participating computers.
Attention: The location of the script have to be: "/var/lib/opsi/depot/opsi-client-agent/opsi-deploy-client-agent" Detailed information can be found in the opsi-getting-started manual on the First steps chapter.
TIP: Some user interfaces include a selection component for paths in the directory structure. If the button "Find Subdirectories" is activated, all directories or files that are contained in the specified path will be listed. To visualize further sections, you can press the button several times. This functionality is, among others, in the "Set Opsi rights" or the "Package installation" interface.
4.21. Define commands
In addition to the predefined server console commands, you can create or remove your own commands, which can be accessed via menu items. It should be noted that different Linux systems may not be able to execute the same commands. Thus, the administrator must be sure that the commands can be executed on the addressed Linux system.
Following data must be or rather could be (marked with a "*") for a command:
-
Menu-Text:
When creating a new command you must make sure that the menu text has not been used already for another command. If a menu text is to be changed, the command must be first deleted with the minus button, and then the new command can be entered. -
Description*:
If a more detailed description is stored, then it appears as a tool tip text on the command. -
Superior menu*:
Determines in which menu the new command should appear as a menu item. In the case that field is empty, then the menu entry will be directly assigned to the "Server console" menu. -
Position *:
The position determines the order (small numbers comes first) of the menu points in total, and thus within each respective menu. If alphabetical order should be displayed, all items must be set identically (e.g., all 0). Should the the field remain empty, then the position 0 is assigned by default. -
"Sudo" rights *:
If one of the commands in the command list requires administrative rights, a check mark must be set on "Required root privileges" afterwards the commands in the list are automatically executed with the keyword "sudo". -
Command list:
For the command list, the Linux commands must be entered line by line, so that they can be executed sequentially. Caution: Command can be tested or executed on the SSH server by means of a button without creating an extra menu point. -
Data sources* (on the command list):
Additionally methods can be stored as a data source. Before the command can be executed, the parameters are overwritten with the result of the applied method. The following parameters are possible:-
Interactive input:
It is possible to specify parameters for the commands or to identify them for an interactive output. This is done with the following format "<<< This text will be displayed to the user and replaced by the user input >>>" , it is recommended though to write a sample input for the parameter for the user text. -
Selected client names / Selected client IP addresses
-
Selected depot names / Selected depot IP addresses
-
configserver name
-
Connected SSH servername
Note: Except for "Interactive Input", the return of the methods can also be formatted, for example, into a comma separated list. In the interface, the data source can be tested, and also insert it into the location marked in the field of the command list.
-
|
- On Linux, commands can be combined using two commercial ANDs ( "&&"). However, it must be ensured that the second command, if needed, is executed with administrative rights, since this is not done automatically. Example: Requires root privileges: "activated", command list: "apt-get update --yes && sudo apt-get upgrade --yes". + - During the execution, no user input can be made. It is necessary to control all the inputs via the command \ parameters (example: "--yes" option for "apt-get upgrade") |
5. opsi-server
5.1. Overview
The functionality of an opsi-server can be installed on many standard Linux distributions.
There are two different major roles, which can be combined on one server:
-
opsi-config-server
The functionality of the configserver includes the storage and processing of the configuration data in different backends and provisioning this via a web service and on the command line. -
opsi-depot-server
The functionality of the opsi-depot-server includes storing the actual installation files of the software to be distributed, operating systems, boot images and making them available to the client via smb/cifs, https, tftp.
The hardware requirements for these services are generally low, so operating an opsi-server in a virtualization environment is not a problem.
Since version 4.2 the opsi-server is using the in-memory database redis (https://redis.io/). The following data is saved in redis:
-
Session data
-
Log outputs are written as MessagePack data into a redis stream. This stream is then read by the Logviewer, for example (https://msgpack.org/).
-
Statistics such as CPU usage are stored as Time Series in Redis. For this purpose the module RedisTimeSeries is used (https://github.com/RedisTimeSeries/RedisTimeSeries).
The Statistics are read and displayed by Grafana (https://grafana.com/). The grafana dashboard can be reached at the following URL https://<opsi-server>:4447/admin.
5.1.1. Installation and initial operation
The installation and starting of a opsi-server is explained in detail in the separate opsi-getting-started manual.
5.1.2. Samba Configuration
In order to give the client computers access to the software packages, the opsi-server provides shares that can be mounted by the clients as network drives. For Windows Clients the shares are provided by Samba. To configure your samba according to the needs of opsi (or to repair) call:
opsi-setup --auto-configure-sambaAfter changing the Samba configuration it is necessary to restart the Samba service (systemctl restart smbd.service).
5.1.3. The opsiconfd daemon
Opsiconfd is the central configuration daemon of opsi.
All client components (opsi-client-agent, opsi-configed, opsi-linux-bootimage, …) connect to this service to access the configurations in the backends.
The opsiconfd is configured via the file /etc/opsi/opsiconfd.conf, environment variables or command line parameters.
The individual configuration options can be queried using the opsiconfd --help command. To use options every time the opsiconfd is started, the option from the help text can be entered into the configuration file without the --.
Furthermore it is possible to use the environment variables as shown in the helptext.
If the individual approaches are combined, the following sequence applies: Entries in the configuration file overwrite defaults, environment variables overwrite entries in the configuration file, command line parameters overwrite environment variables.
5.1.4. Required system user accounts and groups
-
User opsiconfd
This is the user under which the opsiconfd daemon runs. -
User pcpatch
This is the user the opsi-client-agent uses to mount and read from the depotshare. By default this user has the home directory/var/lib/opsi. The password of the user can be set byopsi-admin -d task setPcpatchPassword. -
Group opsifileadmins
Members of this group have access to opsi package data, such as depot, repository and workbench. The system administrators of the opsi server should therefore be members of this group.
Formerly this group was called pcpatch, since opsi 4.2 opsifileadmins is used as group name by default. If an existing opsi environment is updated to opsi 4.2 the used group name will be kept.
When connecting the opsi server to an Active Directory the group name opsifileadmins must be used in any case.
-
Group opsiadmin
The members of this group can authenticate themselves to the opsi-webservice and thus e.g. work with opsi-configed. Therefore, all opsi administrators should be a member of this group.
5.1.5. Required shares
-
Depotshare with software packages (opsi_depot)
The software packages prepared for installation by the opsi-winst program are located on the depot share.
By default, this directory is located on the opsi server as/var/lib/opsi/depot.
Below this directory there is a directory for each software package with the name of the software package.
The installation scripts and files are then below these directories.This directory is shared read-only as opsi_depot.
In older versions of opsi the corresponding directory was /opt/pcbinand the share was called opt_pcbin. -
Working directory to build packages (opsi_workbench)
At/var/lib/opsi/workbenchyou will find the area to create new packages and from where you should install packages with the opsi-package-manager. This directory is shared as opsi_workbench.Since opsi 4.1 the path can be configured per depot through the attribute workbenchLocalUrl. -
Configuration files of the file-backend (opsi_config)
The configuration files of the file backend are located under/var/lib/opsi/config. This directory is shared as opsi_config.If you work on the files via this share, do not use editors that change the file encoding (Unix/DOS), and remove backup files such as * .bak.
5.1.6. opsi PAM Authentication
opsi uses various PAM-modules for user authentication. So far, different PAM modules have been used for different distributions. The PAM modules used are listed in the following list:
Default: common-auth
openSUSE / SLES: sshd
CentOS and RedHat: system-auth
RedHat 6: password-auth
As you can see from the list, various PAM configurations were used, but these can change again depending on the local PAM configuration. Since these adjustments always required an intervention in the sourcecode, you can now create the opsi-auth file under: /etc/pam.d/ and save your own PAM configuration for opsi. If this file exists, opsi automatically uses this configuration.
The following simple example should clarify the behavior: If you run a Debian/Ubuntu system and receive a PAM error message when logging on to opsi-configed, although an SSH connection to the server can be opened with the same user data, you can create the file /etc/pam.d/opsi-auth with the following content:
@include sshdAfter restarting opsiconfd, opsi will automatically use the sshd-PAM module for authentication.
| Please note that the application of the ACL uses case-sensitive interfaces, whereas authentication via PAM can be case-insensitive. This can result in the fact that despite successful authentication, it is not possible to work with the service because the ACL prevents this. |
5.1.7. opsi LDAP/Active Directory Authentifizierung
Instead of using PAM for authentication it is also possible to use an LDAP server or an Active Directory directly. For this the opsi extension opsi directory connector is necessary. This module is currently a link:http://www.uib.de/www/kofinanziert/index.html [co-funded opsi extension].
The configuration takes place via the file /etc/opsi/opsi.conf.
In the section ldap_auth the option ldap_url must be set.
The ldap_url has the following structure:
ldap[s]://<address-of-ldap-server>[:port]/<base-dn>.
Additionally, if necessary, the option username can be used. This can be used to define which user name should be passed when authenticating to the LDAP/AD. Here the placeholders {username} and {base} can be used.
Example for the connection to an Active Directory or Samba 4:
[ldap_auth]
ldap_url = ldaps://ad.company.de/dc=ad,dc=company,dc=enExample of connection to an OpenLDAP:
[ldap_auth]
ldap_url = ldaps://ldap.company.org:636/dc=company,dc=org
username = uid={username},dc=Users,{base}The opsiconfd must be restarted for the changes to take effect.
5.2. Notes on switching to Samba 4
When Samba 4 had reached stable, the development and maintenance work for the Samba 3 branch was discontinued. As a result, almost all common Linux distributions (client and server versions) come with Samba 4 instead of Samba 3. This results in some changes that will be documented in this chapter.
Samba shares are an essential component for the functionality of opsi. Due to the "general" update to Samba 4, there are a few things to consider that will be briefly explained in the following chapters.
A distinction must be made in which operating mode Samba is executed. A special feature of Samba 4 is the ability to run as a fully-fledged Active Directory-compatible domain controller. In this operating mode (which is called PDC mode in the following chapters for reasons of simplification), there are restrictions that had to be adopted from Active Directory for reasons of compatibility. Most distributions are usually equipped with Samba 4, but only in the normal shares operating mode. Operating a full-fledged Active Directory domain is generally not possible with the standard packages from the distributions. An exception here is the Univention Corporate Server, in which the PDC mode is also integrated in the standard packages.
5.2.1. /etc/opsi/opsi.conf: pcpatch and opsifileadmins
| The restrictions described in this chapter only affect the PDC mode of Samba 4. |
The classic installation variant with the user: pcpatch with the primary group: pcpatch cannot be followed for installations with Samba 4. Since Samba 4 is subject to the basic restrictions of Active Directory, groups with the same name as users (as is usual in Unix/Linux) are no longer allowed. For this reason, a new configuration file has been introduced for Samba 4 installations: /etc/opsi/opsi.conf, which controls how the group is determined for Samba access to the shares. In the case of Samba 4 installations, the group name pcpatch is now renamed via this file and is now called opsifileadmins. This means that the users which must have access rights to the shares of opsi (opsi-packagers) under Samba 4 cannot become a member of the pcpatch group, but must be a member of the opsifileadmins group.
Furthermore, in this case the user pcpatch must now be created as a fully-fledged domain user and no longer as a system user, since otherwise he cannot access the domain shares.
These steps are carried out automatically when installing opsi on a Univention Corporate Server, if the installation process detects that Samba 4 is running in PDC mode.
Besides the UCS installations, currently there are no other default Active Directory configurations. So these steps have to be done manually for any other Samba 4 Active Directory domain contoller installation. During future updates, the opsi system checks for the required user configuration and does not try to create users, that already exist.
For any questions please contact opsi support. In case you do not have an opsi support contract, please contact info@uib.de.
5.2.2. Shares Configuration
| The changes described in this chapter are relevant for all operating modes of Samba 4. |
In Samba 3 the default setting was, that every file or directory was executable by the clients. This behavior has been completely changed in Samba 4. Now all files, that should be executable from the share, must also have the executable bit set on the Unix side.
This is a problem for the operation of opsi. It is not possible to circumvent this behavior via the opsi rights management, as this would require a complete revision of the opsi rights system. This is not possible in opsi 4.
There are two ways to work around the problem with opsi 4.0:
Option 1 (recommended): You can set the following option in smb.conf:
acl allow execute always = trueThis option restores the behavior of Samba 3 for the relevant shares.
This option can be set for individual shares as well as globally. We recommend that you do not set this globally but individually for all opsi shares (unless this has already been set automatically).
This variant may not work with Univention Corporate Server, since a highly modified Samba 4 variant is used here. In this case, use option two.
Option 2: this behavior can be overridden on the affected shares via the individual share configuration using the following option for each member of the pcpatch group (share users):
admin users = @pcpatchOpsi has been using this fix for a while with UCS >= 3 and Samba 4. With this fix, the Samba process of the user is executed with elevated rights.
Opsi automatically sets this option for the opsi_depot share for Samba 4 distributions via opsi-setup --auto-configure-samba. Since this share is only mounted read-only, the security risk is relatively low.
| For all other shares, that are mounted as read/write, it should be borne in mind that with this fix the Samba process runs with elevated rights. This can be a potential risk. No exploits are currently known for this vulnerability, but of course this is no guarantee that such an exploit does not exist. |
| The Linux smb daemon has a bug. This is in combination with the opsi_depot share definition in smb.conf. The oplock parameters must be removed on existing installations. New opsi installations and, accordingly, new shares are created without oplocks. |
5.2.3. Access to shares: clientconfig.depot.user
| This restriction affects all operating modes of Samba 4. |
When using Samba 4, it may be necessary to explicitly specify the domain/user combination with which to mount the depot share. There is also the new setting: clientconfig.depot.user. If there is no such setting, the user pcpatch is used.
The value of this setting has the syntax: <domain name>\<user name>
For example, the setting: clientconfig.depot.user = opsiserver\pcpatch indicates that when mounting the depot share the authentication will be done as domain opsiserver and as user pcpatch.
Such a setting can be created via opsi-configed:
Server configuration / clientconfig / right mouse button: Add standard configuration entry.
Such a setting can also be created on the command line (whereby pcpatch must be replaced by the desired value e.g. opsiserver\pcpatch):
opsi-admin -d method config_createUnicode clientconfig.depot.user "clientconfig.depot.user" pcpatchThis system-wide setting can be customized per client (e.g. in configed in the Host parameters tab).
5.3. opsi command line tools and processes
5.3.1. Tool: opsi-setup
This program is something of a Swiss army knife for configuration. Opsi installation scripts use opsi-setup as well as various other common maintenance and repair tasks.
Some common opsi-setup tasks include:
-
Depot server registration
-
File access rights correction
-
Backend data storage initialization
-
Backend upgrades (from 3.4 to 4.0)
-
MySQL backend configuration
-
Default configuration editing
-
Backend cleanup
-
Essential Samba share configuration
-
Essential DHCP configuration
The opsi-setup --help command switch displays the following options:
Usage: opsi-setup [options]
Options:
-h, --help show this help
-l log-level 0..9
--log-file <path> path to log file
--backend-config <json hash> overwrite backend config hash values

-
--ip-address <ip>
Set the ip-address for opsi-server and don’t resolve by name. -
--register-depot
This option is used to register an opsi-server as depot on a opsi-config-server. For details see:
-
--set-rights [path]
Sets file access rights on all opsi directories:-
/tftpboot/linux -
/var/log/opsi -
/var/lib/opsi -
/var/lib/opsi/depot -
/var/lib/opsi/workbench(or a different depot path) -
/etc/opsi
You may state a path as argument to limit access rights of this specific directory.
For example:
opsi-setup --set-rights /var/lib/opsi/depot/winxppro/drivers -
-
--init-current-config
initialize the configured backend. This command should always be used after changing the configuration file.
/etc/opsi/backendManager/dispatch.conf -
Commands:
--update-mysql
--update-file
are used to upgrade the backends from one opsi version to the next one.
For details see the releasenotes-upgrade-manual. -
--configure-mysql
Configures the MySQL database for the first time.
-
--edit-config-defaults
Edits opsi-configed default values.
Figure 48. Dialog: opsi-setup --edit-config-defaultsFor example:
- clientconfig.depot.id
-
Configures the name of the default depot server.
- clientconfig.depot.drive
-
Configures a drive letter to mount the installation data share. You can either select a specific drive letter or choose the dynamic option. With the dynamic option enabled, the client will try to automatically select a drive letter from those not in use.
- license-management.use
-
Defines if netboot products should get license keys from license management or from the product properties.
- product_sort_algorithm
-
Defines the algorithm used to calculate the product installation sequence.
-
--cleanup-backend
Checks the current backends for integrity and removes obsolete or unreferenced entries.
Examples for entries that may be removed are products without reference (not installed on depot / client), host-groups without a parent and configstates without configuration.
| Backup your backend configuration with opsi-backup as standard best practice. |
-
--auto-configure-samba
Creates opsi share entries in the/etc/samba/smb.confconfiguration file. -
--auto-configure-dhcpd
Creates needed DHCP daemon configuration file entries.
Don’t use this option if you don’t plan to use dhcpd on the opsi server.
More details in the opsi-getting-started manual.
5.3.2. Tool: opsi-package-manager: (un-)install opsi-packages
The opsi-package-manager is used for (un-)installing opsi-product-packages on an opsi-server.
To install an opsi-product-package, the opsi system user opsiconfd must be able to read the package. Therefore, it is strongly recommended to install those packages at /var/lib/opsi/workbench (or other subdirectory).
The opsi-package-managers log file path is /var/log/opsi/package.log.
Silent package install (install without prompts):
opsi-package-manager -i softprod_1.0-5.opsi'Install a package (with prompts after each property):
opsi-package-manager -p ask -i softprod_1.0-5.opsiReinstall a package (package reinstall for everyone who has it installed):
opsi-package-manager -S -i softprod_1.0-5.opsiReinstall a package (package reinstallation with dependencies):
opsi-package-manager -s -i softprod_1.0-5.opsiOr:
opsi-package-manager --setup-with-dependencies --install softprod_1.0-5.opsiSilent package uninstall (uninstall without prompts):
opsi-package-manager -r softprodExtract and rename a package:
opsi-package-manager -x opsi-template_<version>.opsi --new-product-id myprodYou may install a package with a different product id. Helpful when a custom Windows netboot product derives from an existing package, and such package updated in the meantime.
opsi-package-manager --install win7-x64_1.2.3.opsi --new-product-id win7-x64-custom
Please note that products installed in such a way will not be automatically updated by opsi-package-updater.
|
Running opsi-package-manager with the --help switch lists all possible options.
Please note:
-
Multi-depot-server environments use the
-dor--depotsoption exclusively. -
The
-doption copies the opsi-package to the target servers/var/lib/opsi/repositorydirectory before installing. Please make sure that there’s enough free space on the target server file system. See also: Section 9.15, “opsi-server with multiple depots (free)” -
If package installation fails due to lack of free space on your target’s temporary folder, you can specify a different temporary folder with the
--temp-diroption.

Use opsi-package-updater to download opsi products from one or more repositories and install them on the server. In addition, you can trigger opsi-package-updater with a cronjob to synchronize depot servers and for automatic package updates.
opsi-product-update will use repositories as their source to fetch new opsi packages.
You can configure each repository’s access and behavior individually.
Configure the General settings at the /etc/opsi/opsi-package-updater.conf file.
Usage
The opsi-package-updater works with different modes, each with its own help module options. You can display help with the --help switch.
# opsi-package-updater --help

--repo <name of a repository>limits the actions of the given repository. Thelist --active-reposoption lists available repositories.
Different modes result in different behavior.
The install, update and download modes load packages from a repository, whereas list displays information.
install mode installs new packages.
update mode overhauls installed packages to a newer version.
Both modes don’t require other parameters.
Example: Installing all available packages on all repositories:
opsi-package-updater installThe modes install and update limit the actions to specific products by using their ID.
Example: Updating the packages for the products firefox and javavm:
opsi-package-updater -vv update firefox javavmYou can specify the package source with --repo id.
Example: Installing ubuntu package from the uib_linux repository:
opsi-package-updater -vv --repo uib_linux install ubuntu
opsi-package-updater installThe download mode allows to download packages without installing them afterwards.
The --force switch forces the download of a package, even if this version is already installed on the server.
The modes install and update allow to limit the actions to specific products by handing over their ID.
Example: Updating the packages for the products firefox and javavm:
opsi-package-updater -vv update firefox javavmIn combination with the --repo switch the package source can be limited.
Example: Installing the package for ubuntu from the repository uib_linux:
opsi-package-updater -vv --repo uib_linux install ubuntuThe mode download allows to download packages without installing them afterwards.
The switch --force forces the download of a package even though this version is already installed on the server.
Through list --active-repos the active repositories are shown.
The information consists of name, address and if applicable the description of the repository.
You can display active repositories using list --active-repos.
The information displayed is name, address, and, if available, the repository description.
Through list --products the available products per repository are shown.
To display possible updates use list --updatable-products.
This option only considers product already installed.
Finally, the update can begin using update.
list --products displays available products
list --updatable-products displays available updates.
Installed products are only considered using the aforementioned command. Product update is kicked off via update.
opsi-package-updater list --updatable-packages
opsi-package-updater -v updateRepository Configuration: Access
Repository configurations are specified in /etc/opsi/package-updater.repos.d/.
You will find a commented template with all possible configuration options in file example.repo.template.
There are two kinds of repositories - internet and opsi-server repositories.
Internet Repositories
Example: download.uib.de
You configure this repositories by:
-
baseURL (for example http://download.uib.de)
-
dirs (a list of directories for example: opsi4.0/products/essential)
-
and for password protected repositories username and password
-
an alternative to password protected repositories, is certificate authentication if the repository supports it. For this, you need to configure authcertfile and authkeyfile with the full path to the clientcertificate and keyfile.
-
If a HTTPS baseURL is used and the server signature should be verified, you need to set verifyCert to true. At the moment the default is false.
You can configure access through proxy, if required. To use a common proxy for all repositories, specify it at the opsi-package-updater.conf file. This file requires at least opsi-utils 4.1.1.33. All repositories without their own proxy use this configuration.
baseUrl = http://download.uib.de
dirs = opsi4.0/products/localboot
username =
password =
proxy =opsi-server
A repository has the opsi-server type, if the configured ID points to another opsi-server. You can specify such ID in the repository configuration file, under the item opsiDepotId.
opsiDepotId = mainserver.my.lanYou can set the central config server’on an 'opsi-depot-server. As a result, opsi-package-updater will fetch packages from the /var/lib/opsi/repository directory of such central server.
Repository Configuration: Behavior
For each repository you have to configure which actions to run:
-
autoupdate: Newer versions of installed packages will be downloaded and updated
-
autoinstall: Packages not yet installed will be downloaded and installed
-
autosetup: Clients using this product are set to setup, on the action request column, once all new packages are downloaded and installed on the server.
-
onlyDownload: Opsi downloads new packages, but no further actions take place.
-
ignoreErrors: Tries to continue downloading/updating even after errors occured when processing any package.
Administrators use this option together with notifications, to trigger a notification email. This way, the administrator can install the packages at a convenient time in the future.
In addition, you can send all these clients a Wake-On-LAN signal to install the new software. Furthermore, opsi-product shutdownwanted ensures that clients power off after the installation.
-
time window for autosetup: You can specify a time window which may be used to change the client action requests to setup.
-
Automatic WakeOnLan with shutdown: If there’s new software, Clients could be woken up and shutdown after installation automatically.
5.3.4. Tools for opsi API access: opsi-admin & opsi interface page
opsi 3.0 introduced a python library which provides an API for opsi configuration. The opsiconfd provides this API as a web service that can be accessed in multiple ways.
In the browser: opsi admin page
Versions 4.2 interface and info page merged into the new admin page. Point your browser to https://<opsi-server>:4447/admin to access. You must access with opsiadmin group credentials.
The first Blocked Clients tab displays a list of all blocked clients. Clicking the unblock button releases this client. You can unblock clients individually by IP or unblock all clients en masse.
With Delete client sessions you can delete all client sessions.
The user receives feedback in a text box under the input fields. The server’s JSON response is also output.
The RPC-Info tab contains a table of the last RPC calls. Click the header bar to sort the table.
The RPC-Interface tab contains the former interface page. With the interface you can make API calls. The request and the response is displayed as JSON.
You can use the Redis interface to make redis calls. The response from the server is displayed in JSON.
The tab Grafana redirects the user to the Grafana dashboard of the opsiconfd. There you can find information about the load history of the opsiconfd.
If the Grafana server is running on the same host as the opsiconfd and no user and password have been set with the configuration variable grafana_internal_url, a new Grafana user is created in the database and the variable grafana_internal_url is adjusted (example: http://opsiconfd:passwort@<host>:3000). The creation of the user takes place when starting opsiconfd or calling opsiconfd setup. Grafana can be called via the admin page (https://<opsi-server>:4447/admin). Clicking on the appropriate tab will redirect to https://<opsi-server>:4447/metrics/grafana/dashboard. The endpoint metrics/grafana/dashboard creates and opens the dashboard in Grafana. On redirection the opsidashboard user is created if he does not exist. The opsidashbord user is used for the automatic login in Grafana and gets a random password on each call.
On the commandline: opsi-admin
At the command line opsi-admin provides an interface to the opsi API. There’s an interactive mode and a non-interactive mode for batch processing from within scripts.
The opsi-admin --help switch displays a list of available command line options:
$ opsi-admin --help
Usage: opsi-admin [options] [command] [args...]
Options:
-h, --help Display this text
-V, --version Show version and exit
-u, --username Username (default: current user)
-p, --password Password (default: prompt for password)
-a, --address URL of opsiconfd (default: https://localhost:4447/rpc)
--opsirc Path to the opsirc file to use (default: ~/.opsi.org/opsirc)
An opsirc file contains login credentials to the web API.
-d, --direct Do not use opsiconfd
--no-depot Do not use depotserver backend
-l, --log-level Set log level (default: 3)
0=nothing, 1=essential, 2=critical, 3=error, 4=warning
5=notice, 6=info, 7=debug, 8=debug2, 9=confidential
-f, --log-file Path to log file
-i, --interactive Start in interactive mode
-c, --colorize Colorize output
-S, --simple-output Simple output (only for scalars, lists)
-s, --shell-output Shell output
-r, --raw-output Raw output
--exit-zero Always exit with exit code 0.The opsi-admin command interacts by way of the opsi web service or first hand with the data backend. To work via the web service, you must specify username and password together with a URL. The opsi-admin command defaults to the currently logged-in user but allows you to specify a different username with --username.
For security, you want to avoid plain text passwords when using this command in scripts. This prevents unauthorized users from capturing the credential values. Use an opsirc file to secure your credentials or, as an alternative, use the -d option for direct data access.
opsi-admin includes an interactive mode, the -i switch, often used with -c, for colored display, and -d for direct data access. The full combined command becomes opsi-admin -i -c -d, or opsi-admin -idc for short.
Interactive mode uses the Tab key for navigation. The tab key allows you to navigate through the multiple choice options or input text fields. Page up and down scroll through the entire screen.
Options -s and -S generate an output format which scripts can easily parse through.
Besides API-request based method calls, there’s a collection of function ‘tasks’ which combine method calls to perform complex or specific jobs.
Usage of a connectionsettings file - opsirc
Starting on version 4.1.1.30, opsi-admin allows you to save web service connection configuration in a file. This allows you to use the web service without retyping your credentials every time you connect from command line.
By default, opsi-admin searches for credentials at ~/.opsi.org/opsirc but you can specify a different path using the --opsirc switch, allowing you to maintain various configuration files.
An opsirc file has the following contents:
address = https://seeing.the.ramp:4447/rpc
username = tony
password file = ~/.opsi.org/tonys_secretEverything in an opsirc file is optional. If the file is empty or doesn’t exist, opsi will use the default values.
In the previous example, the ~/.opsi.org/tonys_secret file keeps the password and opsi in turn, reads this information from the specified path location. This file in turn, contains the password.
Although not recommended, you can state the password in plain text in the opsirc file:
address = https://seeing.the.ramp:4447/rpc
username = tony
password = first900Typical use cases
opsi-admin -d task setupWhereInstalled "softprod"opsi-admin -d method host_getIdentsopsi-admin -d method host_delete <clientname>For example:
opsi-admin -d method host_delete "pxevm.uib.local"opsi-admin -d method host_createOpsiClient <full qualified clientname>For example:
opsi-admin -d method host_createOpsiClient "pxevm.uib.local"opsi-admin -d method setProductActionRequest <productId> <clientId> <actionRequest>For example:
opsi-admin -d method setProductActionRequest win7 pxevm.uib.local setupopsi-admin -d method setHostDescription "dpvm02.uib.local" "virtual client"This uses the option -S so that every client is on its own line.
Filtering OpsiClient avoids displaying the server IDs.
You can use this output in other programs or calls.
opsi-admin -dS method host_getIdents '' '{"type": "OpsiClient"}'opsi-admin -d method productOnClient_getObjects '["productVersion", "packageVersion", "installationStatus"]' '{"installationStatus": "installed"}'opsi-admin -d task setPcpatchPasswordSets the password of the pcpatch user for Unix, samba and opsi.
5.3.5. Server processes: opsiconfd and opsipxeconfd
opsipxeconfd provides the named pipes to control the PXE boot process in the tftpboot directories.
The configuration file is /etc/opsi/opsipxeconfd.conf
The log file is /var/log/opsi/opsipxeconfd.log.
The opsiconfd provides the opsi API as JSON web service and other important tasks. opsiconfd is opsis central service, and allows for communication with all clients.
Since its central for communication, monitoring this process and its load is important. You use the opsiconfd info page as a tool to monitor this service.
5.3.6. Server process: opsi-tftpd-hpa
The opsi-tftpd-hpa is a standard tftpd-hpa, with the expanded ability to handle named pipes.
By default, the opsi-tftpd-hpa runs with its own systemd service.
The service starts with a default or simple verbose parameter. You can modify this parameter to get additional information for troubleshooting or analysis purposes. Enter the following command to change verbosity:
# systemctl edit --full opsi-tftpd-hpa.serviceReplace the -v parameter by --verbosity 7 and restart the service.
# service opsi-tftpd-hpa restart| on Debian 8 the edit operation is not available. However there is a workaround: |
# cp /lib/systemd/system/opsi-tftpd-hpa.service /etc/systemd/system/opsi-tftpd-hpa.service
# vi /etc/systemd/system/opsi-tftpd-hpa.service
# systemctl daemon-reload
# service opsi-tftpd-hpa restart5.4. Web service / API methods
5.4.1. object oriented methods
Since opsi 4 we have to different kinds of API methods:
-
object oriented methods
-
action oriented methods
Overview
The opsi4 backends are based on objects. An object has a set of attributes.
As an example serves here the object Product. The object of type Product which describes the opsi package javavm looks for example like this:
"ident": "javavm;1.6.0.20;2"
"id": "javavm"
"description": "Java 1.6"
"changelog": ""
"advice": ""
"userLoginScript": ""
"name": "SunJavaRuntimeEnvironment"
"priority": 0
"packageVersion": "2"
"productVersion": "1.6.0.20"
"windowsSoftwareIds": null
"productClassIds": null
"type": "LocalbootProduct"
"licenseRequired": false
"setupScript": "javavm.ins"
"updateScript": ""
"uninstallScript": "deljvm.ins"
"alwaysScript": ""
"onceScript": ""
"customScript": ""For each object there is a set of operations. Usually these are:
-
getObjects: returns a list of objects that match the specified filter. If a list of attributes is specified, only these will be populated from the backend.
-
getHashes: Like getObjects, except that unchecked raw data from the backend is delivered directly. Works more performant than getObjects, but should be used with caution.
-
getIdents Returns a list of object IDs that match the specified filter. The returnType can be used to select the data structure of the elements in the result. Possible values are: unicode, list and hash.
-
insertObject': Creates a new object. If the object already exists, it will be completely overwritten with the new values. Attributes that are not passed (or passed with the value null) will be set to null in the backend.
-
updateObject': Updates an object. Attributes that are not passed (or passed with the value null), will not be changed in the backend. If the object does not exist, no change takes place, no object is created.
-
createObjects: An object or a list of objects can be passed. Each object is passed internally to insertObject.
-
updateObjects: An object or a list of objects can be passed. Each object is passed internally to insertObject if it does not exist yet, otherwise to updateObject.
-
create: Creates a new object and takes all possible attributes as single parameters. Internally createObjects is used. Existing objects will be overwritten completely.
-
deleteObjects: Deletes a list of objects. It is mandatory to pass a list. Only the attributes identifying the object (type/id/ident) are used to select the objects to be deleted.
-
delete: Deletes the object identified by the specified parameters.
| To update an object, it is usually a good idea to use the updateObjects method. For example, productOnClient_updateObjects can be used to update the state of a package on a client. Whether the object already exists or not is then irrelevant. |
The names of the methods are composed of:
<object-type>_<operation>
Thus they differ from the legacy methods from opsi 3.x which usually start with get, set or create.
The getObjects methods have two optional parameters:
-
attributes
-
filter
The attributes parameter is used to query only certain attributes of the object, which can provide speed advantages. If a list of attributes is specified, only these are read from the backend. The remaining attributes are returned with the value null. Attributes that identify the object (type/id/ident) are always filled. If all attributes should be read (default), null or [] can be passed as attributes.
Example for the method product_getObjects, parameterized with attributes:["name"] for the package (Product) javavm:
"onceScript": null,
"ident": "javavm;1.6.0.20;2",
"windowsSoftwareIds": null,
"description": null,
"setupScript": null,
"changelog": null,
"customScript": null,
"advice": null,
"uninstallScript": null,
"userLoginScript": null,
"name": "Sun Java Runtime Environment",
"priority": null,
"packageVersion": "2",
"productVersion": "1.6.0.20",
"updateScript": null,
"productClassIds": null,
"alwaysScript": null,
"type": "LocalbootProduct",
"id": "javavm",
"licenseRequired": nullIf you don’t want to ask for attributes but instead you need to use the second parameter filter you have to pass the attribute parameter as [].
The parameter filter is used to define which objects you want to get. For example if you are using the filter {"id":"javavm"} on the method product_getObjects the backend will return the Product object javavm only.
The filter parameter can be used to filter the list of objects. For example, for product_getObjects the filter {"id": "javavm"} restricts the return to the object with the ID javavm. Multiple passed filter attributes are AND-linked here. If a list of values is passed for an attribute, this results in an OR operation. For strings, a * can be used as a placeholder. If you do not want to filter (default), you can pass null or {} as filter.
Example for product_getIdents with filter {"id":["opsi-client-agent", "opsi-script"], "productVersion": "4.1*"} (returnType = hash):
[
{
}, "id": "opsi-client-agent",
"productVersion": "4.1.0.0",
"packageVersion": "47"
},
{
}, "id": "opsi-client-agent",
"productVersion": "4.1.1.40",
"packageVersion": "1"
},
{
}, "id": "opsi-script",
"productVersion": "4.12.4.21",
"packageVersion": "1"
},
{
}, "id": "opsi-script",
"productVersion": "4.12.4.23",
"packageVersion": "1"
}
]For the methods to which one or more objects are passed, this must be done as a JSON object or a list of JSON objects.
The most important objects are:
-
auditHardwareOnHost (client specific hardware information)
-
auditHardware (client independent hardware information)
-
auditSoftwareOnClient (client specific software information)
-
auditSoftware (client independent software information)
-
auditSoftwareToLicensePool (license management)
-
configState (administration of client host parameters)
-
config (administration of host parameter defaults)
-
group (group administration)
-
host (server and clients)
-
licenseContract (license management)
-
licenseOnClient (license management)
-
licensePool (license management)
-
objectToGroup (group administration)
-
productDependency (product dependencies)
-
productOnClient (client specific information to a product e.g. installation state)
-
productOnDepot (depot specific information to a product)
-
productPropertyState (depot or client specific product property settings)
-
productProperty (definition of product properties)
-
product (product meta data)
-
softwareLicenseToLicensePool (license management)
-
softwareLicense (license management)
In addition to the described objects and methods there are some more for special operations.
This design:
-
is created to transfer information about clients (severals) faster
-
filter data with a unified syntax
-
allows to check all input for correct syntax
This results in improved stability and higher performance.
Host (server and clients)
Example of a OpsiClient:
method host_getObjects [] {"id":"xpclient.vmnat.local"}
[
{
"ident" : "xpclient.vmnat.local",

"id" : "xpclient.vmnat.local"
}
]Most of this data is displayed on the clients tab of the opsi-configed.
Possible types are:
-
OpsiClient
-
OpsiConfigserver (which means implicit this is also a OpsiDepotserver)
-
OpsiDepotserver
The server type have different and additional data.

]| A ConfigState object can’t be created without an existing Config object to refer to. |
AuditHardwareOnHost (client specific hardware information)
Describes the detected hardware types (including the client specific values). The idea is that you can see here the client specific data and in auditHardware only one entry for a network card which is used in all your computers.
Unfortunately in reality this doesn’t work as you might expect.
The attribute state describes if this is current (value = 1) or historic (value = 0) data.
Example of AuditHardwareOnHost objects:

]AuditHardware (client independent hardware information)
Describes the detected hardware types (independent from client specific values). The idea in this object is to see client specific data and in AuditHardware only the generic. That way, for example, you can see here only one entry for a network card, which is used in all your computers.
Unfortunately in reality this idea doesn’t work as you might expect.

]Special methods
Opsi has some special methods. This chapter will introduce some of the more important ones.
configState_getClientToDepotserver
This is in fact also a storage object, but it’s a little aside of the standard. It tells us to which depot a client is currently assigned.
The syntax is
method configState_getClientToDepotserver *depotIds *clientIds
*masterOnly *productIdsExample:
method configState_getClientToDepotserver [] "pcbon4.uib.local"
[
{
"depotId" : "bonifax.uib.local",
"alternativeDepotIds" :
[
],
"clientId" : "pcbon4.uib.local"
}
]Communication with hosts
The hostControl methods are used to communicate and control the clients.
Since opsi 4.0.3 we strongly recommend to use the hostControlSafe methods.
All hostControlSafe or hostControl Methods have as last parameter the hostIds. The hostIds are the list of clients this method should work on.
In all hostControlSafe methods this parameter is not optional, if you want to send a method to all clients you have to give a "*". In the older hostControl methods it is allowed to omit this parameter, which means send to all. This has caused some trouble to people which tried this with methods like
hostControl_reboot. So with opsi 4.0.3 we broke the backward compatibility and now an empty hostIds is not any more allowed for the hostControl_reboot and hostControl_shutdown methods.
-
hostControlSafe_execute
Excute a command on the client.
Connect to the opsiclientd of the givenhostIdsand tell them to startcommand.
Parameters:command hostIds -
hostControlSafe_fireEvent
Starts a opsiclientd event on the client.
Connect the opsiclientd of the givenhostIdsand tell them to start theevent.
Parameters:event hostIds -
hostControlSafe_getActiveSessions
Get information of the logged on users on the client.
Connect the opsiclientd of the givenhostIdsand ask for the active sessions.
Parameters:hostIds -
hostControlSafe_opsiclientdRpc
Run the web servicemethodof the opsiclientd.
Connect the opsiclientd of the givenhostIdsand tell them to run the web servicemethodusing the givenparameters. This is the most generic hostControlSafe method, because you may start any possible method. The best way to find out what is possible, is to have a look at control interface https://<clientId>:4441
Parameters:method *params hostIds -
hostControlSafe_reachable
Checks if the opsiclientd is reachable.
Connect the opsiclientd of the givenhostIdsbut do not login.
Parameters:hostIds -
hostControlSafe_reboot
Reboot the clients.
Connect the opsiclientd of the givenhostIdsand starts a reboot.
Parameters:hostIds -
hostControlSafe_showPopup
Shows a pop up message on the clients.
Connect the opsiclientd of the givenhostIdsand starts a pop up windows with themessage.
Parameters:message hostIds -
hostControlSafe_shutdown
Shutdown the clients.
Connect the opsiclientd of the givenhostIdsand starts a shutdown.
Parameters:hostIds -
hostControlSafe_start
Sends a wakeOnLan signal the clients.
This is the only hostControlSafe method that is not use by the opsiclientd from a client.
Parameters:hostIds -
hostControlSafe_uptime
Asks for the clients uptime.
Connect the opsiclientd of the givenhostIdsand get the clients uptime in seconds.
Parameters:hostIds
log_read / log_write
-
log_read
Reads a opsi log file from the server.
Parameters:logType *objectId *maxSize
Possible logTypes are instlog (opsi-winst), clientconnect (opsiclientd), userlogin, bootimage, opsiconfd. The objectId is normally the clientId to which the log belongs. -
log_write
Writes a opsi log file to the server.
Parameters:logType data *objectId *append
Logtypes and objectId see above,append(true/false) (Default = false) should the log be appended to an existing log.
Tutorial: Working with groups
The following tutorial will show how to use the opsi interface from the commandline and work with groups of hosts in opsi.
We want to work with group objects and therefore need to work with those functions whose names start with group. Opsi does distinguish between groups of the type ProductGroup and HostGroup. The first is used for product groupings and the last is used for grouping hosts.
Creating a group of hosts is possible through the method group_createHostGroup. The parameters of the method are id, a description, notes and the parentGroupId (ID of the parent group). Only the ID is required - everything else is optional. The ID is also the name of the group.
| In opsi 4.0 groups are identified by their ID. This ID must be unique throughout the opsi groups. |
To create a first group from the commandline we can now issue the following command:
opsi-admin -d method group_createHostGroup rechner_wenselowski "Nikos computer"To check if our group was created we use group_getObjects.
opsi-admin -d method group_getObjects '' '{"id": "rechner_*", "type": "HostGroup"}'To create some hierarchy we need to also specify the ID of the parent group.
opsi-admin -d method group_createHostGroup "rechner_wenselowski2" "Undergroup" "" "rechner_wenselowski"We can use the call to group_getObjects from earlier to see that our group was indeed created.
Opsi has a default group that behaves like a directory service - i.e. OpenLDAP - that means, that a client can only be member of one group. There is a root group with the ID clientdirectory that assumes that exact behavior for any group / client inside. Any client not in a subgroup of clientdirectory will be moved to another special group with the ID NOT_ASSIGNED. Anyone working with that groups is responsible that clients are not member of multiple subgroups of clientdirectory.
Working with the clients is easy now. You probably have noticed that our earlier query to opsi did not show us any signs of clients. That is because the assignment from a client to a group is taken care of another type of object: objectToGroup.
To have a client at hand we will first create one:
opsi-admin -d method host_createOpsiClient "wenselowski-test.uib.local"This client we now want to add to the group we created previously.
opsi-admin -d method objectToGroup_create "HostGroup" "rechner_wenselowski2" "wenselowski-test.uib.local"Noticed the HostGroup as the first parameter? That is again our group type. To check if the creation was successful we can execute the following command:
opsi-admin -d method objectToGroup_getObjects '' '{"groupType": "HostGroup", "groupId": "rechner_wenselowski2"}'If for some reason we want to remove a client we can do this as well. Just execute the following:
opsi-admin -d method objectToGroup_delete "HostGroup" "rechner_wenselowski2" "wenselowski-test.uib.local"Finally you may want to clean up the groups we created earlier. The following statements will do this for you:
opsi-admin -d method group_delete "rechner_wenselowski"5.4.2. Action oriented methods
The action oriented methods where introduced in opsi 3. These methods are still available and will still be maintained. Technically methods are mapped to the object oriented methods internally.
Here comes a short list of some methods with a short description. This is meant mainly for orientation and not as a complete reference. The short description does not necessarily provide all information you need to use this method.

5.4.3. Backend extensions
opsi 4 brings the feature of a backend extender that allows to extend to core functionality through additional methods that will be served as an extension to the API.
The set of standard API methods will be created through opsiconfd
by overlaying the in the .conf-files in /etc/opsi/backendManager/extend.d
defined methods.
Backend extensions can be used to implement specific tasks for additional features.
These extensions have to be written as Python code.
Extensions are loaded "on to" an BackendManager-instance and can
reference it with self.
5.4.4. Accessing the API
The API uses JSON-RPC 1.0 over HTTP for communication. We use basic authentication.
To use this interface POST your calls to the path rpc of your opsi
server, i.e. https://opsiserver.domain.tld:4447/rpc.
5.5. opsi-backup
5.5.1. Introduction
Like any other system, an opsi-system should also be backed up. Since opsi is a central tool for Windows client and Windows server management, the opsi-server should be backed up. This manual is intended to give an insight into the backup strategy of opsi and also on topics such as restoring and the "DisasterRecovery" of opsi.
5.5.2. Preconditions for a backup
There is not really a prerequisite for backing up an opsi-system. Once you have located the central files and backends of the opsi system, you can save them using various methods. The following instructions should not only answer the question: "What should be backed up?", but also document a way what a backup strategy for an opsi-system could look like.
The backup script should be run as root, either manually or a root cronjob, so that you can read the configuration of opsi and also determine the system configuration. Furthermore, the mysqldump program should be installed for a backup of the mysql backend, which can usually be found in the client packages of mysql.
5.5.3. Quick Start
Creating a backup:
opsi-backup create opsi_backup.tar.bz2Creates a backup of the currently used backends, as well as the configuration files, in the current directory with the name opsi_backup.tar.bz2.
Restoring backend data (without configuration files):
opsi-backup restore opsi_backup.tar.bz2Restores the data from the backup file opsi_backup.tar.bz2 in the current directory.
Completely restoring a backup including configuration files:
opsi-backup restore --backends=all --configuration opsi_backup.tar.bz25.5.4. Basic parts of opsi
Opsi can roughly be divided into five parts. The following five parts are specific to opsi and may vary from system to system depending on the configuration.
Opsi configuration
By far the most important part of opsi is the configuration. True to LSB (Linux Standard Base), the configuration of opsi is located under /etc/opsi.
This directory mainly contains the backend configuration, the webservice configuration and the SSL certificate for the webservice. Furthermore, backend extensions are stored here, the configuration of opsipxeconfd, opsi-package-updater with its repositories and also the modules file, which unlocks your co-financed modules.
The directory /etc/opsi must be backed up in order to achieve a full recovery after an incident.
This part is secured with opsi-backup.
This backup also has another advantage:
If you have changed many configuration options of opsi and the system no longer works properly, it is usually easier and quicker to return to a previous working version than troubleshooting.
Opsi backends
The opsi backends are listed in the following chapter. These form the heart of the opsi data storage. All clients, products, configurations, statuses, etc… are stored in the respective data storage.
Opsi offers the following data backends:
| Backend | Description |
|---|---|
file-Backend |
File-based backend, currently the default |
mysql-Backend |
MySQL-based backend (since opsi 4.0) |
dhcp |
Special backend which is used in combination with dhcpd on the opsi-server |
If you do not know which backend you are using, you are probably using the file backend. Opsi is also designed to use multiple backends at the same time. Which backends are used for which functions of opsi is configured in /etc/opsi/backendManager/dispatch.conf.
This part is secured with opsi-backup.
Opsi depot share
The depot files are interesting because they contain the actual files of the software to be distributed. The localboot products as well as the netboot products each have their files stored under /var/lib/opsi/depot. In previous versions of opsi they were located in the directory /opt/pcbin/install.
Depending on how much software is kept on the opsi-server, and how many operating system installations including drivers are stored, this data volume can take on enormous proportions.
There are different approaches to back up these files. The simplest alternative is rsnapshot. However, there are more elegant solutions, such as storing this data in a redundant file system on a SAN, etc.
This part is not backed up by opsi-backup.
Opsi workbench
The opsi workbench area, which is also used as a Samba-share of the same name (opsi_workbench), contains the state of your own software packaging. By default, the directory is /var/lib/opsi/workbench. If this share is used to store your created packages in different revisions, this directory should also be saved.
The rsnapshot tool is also suitable here.
This part is not backed up by opsi-backup.
| Since opsi 4.1, this directory can be configured individually for each depot server, so that different paths are possible. |
Before opsi 4.1, this directory was on non-SLES systems located at /home/opsiproducts.
|
Opsi repository
The directory /var/lib/opsi/repository is used to store opsi packages. Unlike the opsi workbench, it is not used to create opsi packages, but the opsi packages that are stored there should not be removed, in order to simplify a possible synchronization with other servers or the synchronization using opsi-package-updater.
These files are not absolutely necessary for a complete recovery, but can also be saved with the rsnapshot tool.
This part is not backed up by opsi-backup.
TFTP directory
The TFTP directory contains configuration files for booting via PXE.
This directory is located under /tftpboot/ on most systems. On SLES this directory is /var/lib/tftpboot/opsi/.
Possibly modified files are e.g. linux/pxelinux.cfg/default.menu or linux/pxelinux.cfg/default.nomenu.
These files are created with default values when installing opsi-linux-bootimage. These are not absolutely necessary for disaster recovery.
This part is not backed up by opsi-backup.
5.5.5. The opsi-backup program
The command line program opsi-backup is a tool that makes it easy to create and restore backups.
To do this, opsi-backup can be controlled with three basic commands: create, restore and verify.
The --help option gives a detailed overview of all options of opsi-backup.
A backup created with opsi-backup is a raw backup, which means that no files are backed up at the logical level, but backups of the files stored in the backends are made in the corresponding structures.
Such a backup can therefore only be restored for an identical backend configuration.
A backup created with opsi-backup is always a full backup (opsi-backup does not support incremental or differential backups).
It should be noted that opsi-backup does not back up depot files, workbench files and repository files. These files should therefore be backed up in a different way.
The backup file created with opsi-backup is a compressed tar file, the content of which can be viewed accordingly.
opsi-backup --help
A backup created with opsi-backup may contain passwords and PC-keys, among other things, and should therefore be stored securely.
|
Creating a backup
A new opsi backup is created with the command opsi-backup create. If this command is given without further parameters, the program creates an archive with all data of the backends and the configuration. The file name is generated automatically.
Additional program help is available for the opsi-backup create command, which is output using the --help option.
opsi-backup create
opsi-backup create --helpIt is also possible to specify the file name or the target directory of the new backup. To do this, simply add a file name or a target directory to the corresponding command. If a directory is specified, opsi-backup automatically generates a file in this directory.
A file name generated by opsi-backup has the form <hostname>_<opsi-version>_<date>_<time> and is well suited for archiving several backups. If a file name is specified, an older backup with the same name will be overwritten by opsi-backup.
opsi-backup create /mnt/backup/opsi_backup.tar.bz2
opsi-backup create /mnt/backup/In addition, the create command enables the backup to be controlled using the following options:
-
-- backends {file,mysql,dhcp,all,auto} +,
Allows you to select the backends to include in the backup. This option can be specified multiple times to specify multiple backends. The option--backends=allincludes all backends. The default for this option is--backends=auto, which means thatopsi-backuptries to determine the backends in use using the configuration file/etc/opsi/backendManager/dispatch.conf. Currently, the following backends are supported: +mysqlfile,dhcpopsi-backup create --backends=file --backends=mysql opsi-backup create --backends=allIf you are using an unsupported backend (such as ldap), you can convert it with the command opsi-convertto a backend which can be backed up withopsi-backup. -
--no-configuration
Excludes the opsi configuration from the backup.opsi-backup create --no-configuration -
-c [{gz,bz2,none}], --compression [{gz,bz2,none}]
Specifies the compression method with which the archive is to be compressed.nonestands for no compression, the default compression isbz2.opsi-backup create -c bz2 -
--flush-logs
The backup of the mysql backend is done internally with a mysqldump command. This means that the data is backed up exactly as the database is at that time (regardless of whether the data is already on disk or only in memory). Thus, the backup created may be more up-to-date and different from the state of the database files. If you want to avoid this, the data held in memory by mysql must first be written to disk. If the option--flush-logsis specified,opsi-backupwill try to perform this operation (i.e. write the data from memory to disks). However, the corresponding database user of the opsi database needs the corresponding MySQL authorization RELOAD. By default, the opsi user is created without this right! If the user does not have this right (and the option--flush-logsis specified), the backup will fail. Therefore, only use this option if you have previously adjusted the rights of the database user.opsi-backup create --backends=mysql --flush-logsExample
opsi-backup create --no-configuration --backends=all opsi_backup.tar.bz2
Archiving backups
opsi-backup does not have any functionality for archiving backups. The administrator must therefore ensure that created backups are stored securely and versioned.
In addition, opsi-backup never automatically deletes older backup versions (unless they are overwritten with create). Since opsi-backup always creates full backups and no incremental backups, the amount of data can quickly grow to a large size.
The administrator must thus also ensure that older backups are deleted regularly if necessary.
Verifying a backup
With the command opsi-backup verify the archive can be checked for internal integrity. This check is not a logical check of the data, it is a pure check if the data stored in the archive is not corrupted.
Additional help is available for the opsi-backup verify command, which is shown using the --help option.
Example
opsi-backup verify opsi_backup.tar.bz2
opsi-backup verify --help
If the opsi-backup verify command is explicitly ran on the console, it often makes sense to send the output of opsi-backup to the standard output (stdout): opsi-backup -v verify opsi_backup.tar.bz2
|
Listing the contents of a backup
With the command opsi-backup list the contents of a backup will be displayed.
The listing shows whether configuration data is available, and from which backends data is in the backup.
Example
opsi-backup list opsi_backup.tar.bz2Restoring from a backup file
Restoring an archive is done with the command opsi-backup restore. The backends are (by default) imported based on the current configuration. It is therefore not possible to restore a pure backend backup, if an opsi configuration is not available.
The command opsi-backup restore needs a parameter, which is the backup archive from which data is to be restored.
Additional help is available for the opsi-backup restore command, which is output using the --help option.
opsi-backup restore accepts the following options:
-
--backends {file,mysql,dhcp,auto,all}
Specifies the backend to restore.This option may be used multiple times to specify multiple backends. The option--backends=allstands for all backends.
As a default, the option--backends=autois used, which means thatopsi-backuptries to determine which backends to restore from the configuration file/etc/opsi/backendManager/dispatch.conf.opsi-backup restore --backends=file --backends=mysql opsi_backup.tar.bz2 opsi-backup restore --backends=all opsi_backup.tar.bz2If you changed your backend configuration since you have created the backup, the default setting will not restore up any data. -
--configuration
Restores the opsi configuration. This option is not the default for therestorecommand.opsi-backup restore --configuration opsi_backup.tar.bz2 -
--new-server-id=<new-name>
Changes the name of the Opsi Config server after restoring the backup. If there is a host with the ID <new-name>, it will be removed.opsi-backup restore --new-server-id=test.example.org opsi_backup.tar.bz2 -
-f, --force
Before restoring a backup,opsi-backupcarries out a systemcheck to see whether the current opsi installation matches the installation of the backup (opsi version, OS version, host- and domain name). This option can be used to bypass this check.opsi-backup restore -f opsi_backup.tar.bz2Example
opsi-backup restore --configuration --backends=all opsi_backup.tar.bz2
If a backup is restored to a server and there is no backup of the depot folder, you can use opsi-package-updater and opsi-package-manager to download and install all packages from the repository again.
Any changes made to the depot must then be applied again afterwards.
opsi-package-updater download --force
opsi-package-manager --install /var/lib/opsi/repository/*.opsi5.6. opsi data storage (backends)
5.6.1. file backend
When using the file backend the configuration information is stored in ini-files on the server.
Main features of the backend file:
-
Current default backend
-
The files of this backend are located in
/var/lib/opsi/config. -
Is implemented on the assumption that the FQDN of the server on which the backend is used corresponds to the FQDN of the config server.
The content and structure of these files is explained in more detail in the Section 5.7.4, “Files of the file backend” chapter.
5.6.2. mysql backend
mysql backend for inventory data (overview and data structure)
The hardware and software inventory data are by default stored in text files via the opsi file backend. This form of data storage is less suitable for queries and reports. For this, the data can be stored in a SQL database.
Main features of the backend mysql:
-
Optional (not the default backend)
-
For inventory data free of charge, for use with other data you need a paid activation.
-
Finely granulated data structure for data storage and additionally a simplified data model for queries.
-
A history function, which logs changes to the inventory data.
Due to the very different nature of the hardware components to be inventoried, the data structure is roughly structured as follows:
-
A table HOST describes all known clients and provides a unique host_id.
-
There are two tables for each device type:
-
HARDWARE_DEVICE_ …. describes the device e.g. Network card type with PCI-identifier
-
HARDWARE_CONFIG … describes configuration of the specific network card e.g. MAC address. The two tables are linked to each other via the hardware_id field.
-
The situation is similar for the software inventory. Again, the Software table describes the total software found, while the Software_Config table stores the client-specific configuration.
This results in the following list of tables:
HARDWARE_CONFIG_1394_CONTROLLER
HARDWARE_CONFIG_AUDIO_CONTROLLER
HARDWARE_CONFIG_BASE_BOARD

mysql backend for configuration data (overview)
The mysql backend for configuration data has been available since opsi 4.0.
This module is currently a co-financed opsi extension. This means it is not free to use.
Further details can be found in Section 9.1, “Activation of non-free modules”.
The {mysql backend} has the advantage of a higher performance, especially with large installations.
Here is an overview of the data structure:
Initializing the MySQL-Backend
If the MySQL server is not yet installed, this must first be done by:
apt-get install mysql-serverThen a password must be set for the MySQL-user root user':
mysqladmin --user=root password linux123
Since MySQL-Server version 5.7 the previously optional strict mode is enabled by default. This causes the opsi-setup --configure-mysql command to fail. Accordingly, the file /etc/mysql/mysql.conf.d/mysqld.cnf should be edited before the command is executed.The following line must be inserted in the [mysqld] section:sql_mode = NO_ENGINE_SUBSTITUTIONThen the service mysql has to be restarted:` systemctl restart mysql.service`It is now possible to continue. |
The database can now be set up with the command opsi-setup --configure-mysql.
An example session:
In the input dialog, all entries can be confirmed with Enter except for the password.
Next you have to specify in /etc/opsi/backendManager/dispatch.conf that the mysql backend should also be used. A detailed description of this configuration can be found in the Backend configuration chapter of the getting-started manual. The file itself contains a number of examples of typical configurations.
A configuration for the mysql backend (without internal dhcpd) looks like this:
backend_.* : mysql, opsipxeconfd
host_.* : mysql, opsipxeconfd
productOnClient_.* : mysql, opsipxeconfd
configState_.* : mysql, opsipxeconfd
.* : mysqlAfter completing the configuration, you must execute the following commands to use the now configured and converted backend:
opsi-setup --init-current-config
opsi-setup --set-rights
systemctl restart opsiconfd.service
systemctl restart opsipxeconfd.service| The opsiconfd service has no hard dependency on MySQL by default, since opsi can be used without a MySQL-backend, and the service can also run on another server. Please refer to the documentation of your operating system on how to configure this. |
Manual configuration
A manual configuration can be done via the backend configuration file.
By default this is /etc/opsi/backends/mysql.conf.
Since python-opsi 4.1.1.76 it has been possible to force the creation of new connections after a certain time in order to avoid problems with timeouts. One indication of such timeouts can be the message mysql server has gone away.
You can set a timeout by specifying connectionPoolRecycling after how many seconds a new connection should be created.
The default value is -1, which means no forced reconnection.
If this value is set, it should generally be lower than the value for connection timeouts configured on the server (wait_timeout).
Configuration of the MySQL database for external access
The existing database must be configured so that external access is possible, i.e. not only connections from localhost are accepted.
Please refer to the manual of your database for the necessary steps.
5.6.3. HostControl backend
The HostControl backend does not store any configuration data, but is used to control the opsi clients. This includes, for example, starting clients via Wake-On-LAN or sending control commands to the opsi-client-agent.
The configuration of the HostControl backend is done in the configuration file /etc/opsi/backends/hostcontrol.conf. Configuration options are:
-
opsiclientdPort:
Network port for connecting to an opsi-client-agent. -
hostRpcTimeout:
Timeout (in seconds) when connecting to an opsi-client-agent. -
resolveHostAddress:
If this option is set toTrue, when connecting from opsi-server to an opsi-client, the IP address of the client is firstly determined via name resolution. To give preference to the IP address stored in the opsi backend, the option must be set toFalse. -
maxConnections:
Maximum number of simultaneous connections to an opsi-client-agent. -
broadcastAddresses:
Assignment of broadcast addresses and ports to be used for sending Wake-on-LAN broadcasts. Ports can be configured for each broadcast address independently.
5.6.4. HostControlSafe-Backend
A peculiarity of opsi 4.0 methods called without parameters is that it matches all existing objects. For example, the command "host_getObjects" without any parameters returns all host objects. This behavior is somewhat problematic in the HostControl backend. Especially with the two commands: hostControl_shutdown and hostControl_reboot. In these cases, calling these methods without parameters would shutdown or restart all clients.
Therefore with opsi release 4.0.3 two changes were introduced:
-
The methods
hostControl_shutdownandhostControl_rebootare different from the standard opsi 4.0 behavior since this release. These two methods now return an error message when they are called without any parameters. -
A new backend has been introduced (HostControlSafe-Backend), which results in error message for all methods, if they are called without any correct client parameter. To explicity address all clients with a HostControlSafe-Backend method, you can use the
*character:opsi-admin -d method hostControlSafe_shutdown *
For the reasons mentioned above, we recommend using hostControlSafe methods on the console or if you are new to using the service methods.
5.6.5. Conversion between different backends
The opsi-convert command is used to convert the opsi configuration data between different backends. Destination and source can be assigned in different ways:
-
backend name:
By specifying the name, a corresponding backend is specified on the current server. The commandopsi-convert file mysqlconverts the data on the current server from the file backend to the mysql backend. -
Service address
By specifying service addresses, a server can can also be addressed remotely. The service address has the formhttps://<username>@<ipadresse>:4447/rpc. You will be asked for the passwords.
Example:
opsi-convert -s -l /tmp/log https://uib@192.168.2.162:4447/rpc https://opsi@192.168.2.42:4447/rpc
opsi-convert commandline arguments:
usage: opsi-convert [-h] [--version] [--quiet] [--verbose]
[--log-level {0,1,2,3,4,5,6,7,8,9}] [--clean-destination]
[--with-audit-data] [-s OLD SERVER ID]
[--log-file LOGFILE]
source destination
Convert an opsi database into an other.
positional arguments:
source Backend to read data from.
destination Backend to write data to.
optional arguments:
-h, --help show this help message and exit
--version, -V show program's version number and exit
--quiet, -q do not show progress
--verbose, -v increase verbosity (can be used multiple times)
--log-level {0,1,2,3,4,5,6,7,8,9}
Set log-level (0..9)
--clean-destination, -c
clean destination database before writing
--with-audit-data, -a
including software/hardware inventory
-s OLD SERVER ID use destination host as new server
--log-file LOGFILE, -l LOGFILE
Log to this file. The loglevel will be DEBUG.
The backends can either be the name of a backend as defined in
/etc/opsi/backends (file, mysql, ...) or the the url of an opsi configuration
service in the form of http(s)://<user>@<host>:<port>/rpc5.6.6. Boot files
/tftpboot/linux contains the boot files that are required in conjunction with the PXE network boot.
5.6.7. Securing the shares with encrypted passwords
The opsi-client-agent accesses the shares made available by the opsi-server in order to be able to install the software on the client.
The system user pcpatch is used for this. Securing these shares and the authentication data of the pcpatch user are important for: * General system security and data integrity * Protection of licensed software packages against misuse
In order to provide the opsi-client-agent access to the authentication data, a specific key (opsi-host-key) is generated for each client when it is created in opsi. This key is stored (in the file backend) in the file /etc/opsi/pckeys and is transferred to the PC during reinstallation. The transferred key is stored during the installation of the opsi-client-agent in the file c:\program files\opsi.org\opsi-client-agent\opsiclientd\opsiclientd.conf in such a way that only Administrators have access. Likewise, on the opsi-server only root and members of the opsiadmin group have access to the file /etc/opsi/pckeys. This way, each PC has a key that is only known to the PC and the opsi-server and which is protected against access by normal users. With this key the current password of the system user pcpatch is encrypted on the opsi-server and stored in the backend. This encrypted password is read by the client each time the opsi-client-agent is activated, so that the pcpatch password can be changed at any time and the client is notified of the changed password in an encrypted way.
5.7. Important files on the opsi server
5.7.1. Common configuration files in /etc
/etc/hosts
The IP number and IP name of the clients can be entered here (additional names are aliases, and comments start with the "#" character).
Opsi needs the fully qualified hostname (i.e. including the domain) and this can come from /etc/hosts as well from the DNS.
Example:
192.168.2.106 dplaptop.uib.local dplaptop # this opsi-server
192.168.2.153 schleppi.uib.local
192.168.2.178 test_pc1.uib.local # Test-PC PXE-bootpromThe output of:
getent hosts $(hostname -f)should be similar to:
192.168.1.1 server.domain.tld serverIf the result does not look like this (e.g. contains 127.0.0.1 or localhost), you must first correct your /etc/hosts or name resolution.
/etc/group
Two groups must exist here: pcpatch and opsiadmin. All users who are dealing with package management should be member of the group pcpatch. All users who want to use the opsiconfd web service, e.g. via opsi-configed, must be in the opsiadmin group.
/etc/opsi/backends/
Configuration files for the used backends.
/etc/opsi/backendManager/
-
acl.conf
Configuration of the access rights to the opsi methods. This allows access rights for the basic methods of the web service to be restricted to certain users and certain attributes. -
dispatch.conf
Configuration of which of the backends configured under/etc/opsi/backends/should be used for what. -
extend.d/
Directory for backend extensions. So here are for example the scripts that map the opsi 3 methods to the opsi 4 methods.
/etc/opsi/hwaudit/*
Since opsi version 3.2
Here you will find the configuration files for the hardware inventory.
Translations are located in the locales directory.
The mapping between WMI classes (for Windows) or shell programs (for Linux) and the opsi data storage is configured in the file opsihwaudit.conf.
/etc/opsi/opsi.conf
Since opsi version 4.0.2-2
General opsi settings.
Example:
[groups]
fileadmingroup = pcpatchBackground:
The classic installation variant with the user: pcpatch with the primary group: pcpatch does not work with Samba 4. Since Samba 4 is subject to the basic restrictions of Active Directory, groups with the same name as users (as is usual in Unix/Linux) are no longer allowed. For this reason, a new configuration file has been introduced: /etc/opsi/opsi.conf, which controls how the group is determined for Samba access to the shares. In the case of Samba 4 installations, the group name pcpatch is now renamed via this file and is now called opsifileadmins. This means that the users which must have access rights to the shares of opsi (opsi-packagers) under Samba 4 cannot become a member of the pcpatch group, but must be a member of the opsifileadmins group.
/etc/opsi/modules
Since opsi version 3.4
This file is signed by uib gmbh for the activation of non-free features. If this file is changed, it loses its validity. Without this file, only the free features are available.
Directory /etc/opsi/modules.d/
Since opsi version 4.1
Directory reserved for future usage.
Directory /etc/opsi/modules.d/
Since opsi 4.1.
Directory for future use.
/etc/opsi/opsiconfd.conf
Since opsi version 3.0
Configuration file for the opsiconfd service in which settings such as ports, interfaces and logging are specified.
/etc/opsi/opsiconfd.pem
Since opsi version 3.0
Configuration file for the opsiconfd service in which the ssl certificate is stored.
/etc/opsi/opsipxeconfd.conf
Configuration file for the opsipxeconfd service, which is responsible for writing the startup files for the Linux bootimage. Directories, defaults and log levels can be configured here.
/etc/opsi/opsi-package-updater.conf
Configuration file for the opsi-package-updater. See also Section 5.3.3, “Tool: opsi-package-updater”
5.7.2. Boot files
Boot files in /tftpboot/linux
-
pxelinux.0
Boot file that is loaded in the first step by the PXE boot. -
installandminiroot.gz
Installation bootimage, which is transferred via tftp to the client during reinstallation.
Boot files in /tftpboot/linux/pxelinux.cfg
-
01-<mac adress>or<IP-address-in-hex>
Files with the hardware address of the client and the prefix 01- can be found on the opsi-server as client-specific boot files. Usually they are created via opsipxeconfd as named pipes and should initiate a reinstallation of the client. -
default
The filedefaultis loaded if there are no client-specific files. If this file is loaded, the client then continues to a local boot. -
install
Information for the boot of the installation bootimage, which is written from opsipxeconfd into the named pipe.
5.7.3. Files in /var/lib/opsi
/var/lib/opsi/depot
This directory is exported (read-only) as the Samba share opsi_depot.
In old opsi installations this directory was /opt/pcbin/install. If this directory still exists, a symlink references it to /var/lib/opsi/depot.
/var/lib/opsi/ntfs-images
This is the default directory where the partition images are stored, that are used with the netboot product opsi-clonezilla.
/var/lib/opsi/repository
This is the place where opsi-product-packages are saved, which are loaded by the calls of the opsi-package-updater to the server.
This is also the place where opsi-product-packages are saved, which are installed by the calls of the opsi-package-manager if it is called with the option -d.
/var/lib/opsi/workbench
This is the location used to create your own packages.
Other directories
The remaining directories in /var/lib/opsi (config and audit) are directories of the file backend, which is described in the following chapter.
5.7.4. Files of the file backend
/etc/opsi/pckeys
The client-specific opsi-host-keys and also the server key are stored here.
Example:
schleppi.uib.local:fdc2493ace4b372fd39dbba3fcd62182
laptop.uib.local:c397c280fc2d3db81d39b4a4329b5f65
pcbon13.uib.local:61149ef590469f765a1be6cfbacbf491/etc/opsi/passwd
The passwords encrypted with the server key (e.g. for pcpatch) are stored here.
Overview of /var/lib/opsi
The files of the file backend of opsi 4 can by default be found in /var/lib/opsi/config/. The following diagram gives an overview of the directory structure:
/var/lib/opsi-|
|-depot opsi_depot share
|-repository opsi package repository used by opsi-package-updater and opsi-package-manager
|-audit inventory files
!-config/-| config share
|-clientgroups.ini client groups
|-config.ini Host Parameters (Global Defaults)

Configuration files in detail
The following chapters explain the structure of the different configuration files of the file backend.
./clientgroups.ini
This file contains information about the client groups.
[<GroupId>]
<HostId> = 1 #active
<HostId> = 0 #non-active./config.ini
Here you will find the default values of the server configuration as shown in opsi-configed in the host parameters tab.
./clients/<FQDN>.ini
The client-specific configurations are stored in this file. The information is combined with the values from <depot-id>.ini, whereby the settings from <FQDN>.ini take precedence.
These files are structured as follows:
The info section contains all information directly related to the client, for example the description:
[info]
description = <String>
created = <Date> #format: 'YYYY-MM-DD HH:MM:SS'
lastseen = <Date> #format: 'YYYY-MM-DD HH:MM:SS'
inventorynumber = <String>
notes = <String>
hardwareaddress = <MAC> #format: 'hh:hh:hh:hh:hh:hh'
ipaddress = <IP> #format: 'nnn.nnn.nnn.nnn'
onetimepassword = <String>The following section stores the current status of the products on the client. If there are no entries, not_installed: none is assumed.
[<Type>_product_states] #'LocalbootProduct', or 'NetbootProduct'
<ProductId> = <InstallationStatus>:<ActionRequest>More detailed information can be found in the sections belonging to the respective products:
[<ProductId>-state]
producttype = <Type> #'LocalbootProduct', or 'NetbootProduct'
actionprogress = <String>
productversion = <ProdVer>
packageversion = <PackVer>
modificationtime = <Date> #format: 'YYYY-MM-DD HH:MM:SS'
lastaction = <ActionRequest>
actionresult = <ActionResult>
targetconfiguration = <InstallationStatus>/var/lib/opsi/config/templates
This is the location of the file pcproto.ini, which is the standard template for creating new client ini-files and has the same structure. If specific clients should be given different information, you can save a <FQDN>.ini in this directory.
/var/lib/opsi/config/depots/
Here you will find the files of the opsi-depot-server, which are also saved with <depot-id>.ini. Among other things, the connection to the depot is stored here.
[depotshare]
remoteurl = smb://<NetBiosName>/<Path>
localurl = file://<Path>
[depotserver]
notes = <String>
network = <IP>
description = <String>
hardwareaddress = <MAC>
ipaddress = <IP>
inventorynumber = <String>
[repository]
remoteurl = webdavs://<FQDN>:<Port>/<Path>
localurl = file://<Path>
maxbandwidth = <Integer> #in BytesHere you will also find information on which opsi products, in which version, and with which property defaults are installed on the depot.
Product control files in /var/lib/opsi/config/products/
The product control files contain the metadata of the products, e.g. name, properties and their default values, dependencies …
The control files correspond to the control files that are created when creating opsi products in the directory <product name>/OPSI/control.
The control files consist of the following sections:
-
Section [Package]
Description of the package version and packages required for the installation of the package on an opsi-depot-server. -
Section [Product]
Description of the product. -
Section(s) [ProductProperty]
(optional)
Description of editable product properties. -
Section(s) [ProductDependency]
(optional)
Description of product dependencies.
Example:

The required status of the product, which the dependency entry refers to. Typically this is installed, which results in setting this dependency product to setup, if it is not installed on the client yet. -
[ProductDependency]-Requirement type:
Installation order. If the product to which a dependency exists must be installed before the current product can be installed, then this is set to before. If it has to be installed after the current product, this is set to after. If the order is irrelevant, nothing has to be entered here.
Inventory data /var/lib/opsi/audit
This is the location of the inventory data for hardware (*.hw) and software (*.sw).
5.7.5. opsi programs and libraries
Programs in /usr/bin
-
opsipxeconfd
Opsi daemon, which manages the files in the tftp area of the server that are necessary for the PXE boot of the clients. -
opsi-admin
Command line interface to the opsi python library. -
opsiconfd
Opsi daemon that provides the opsi methods as a webservice and much more. -
opsiconfd-guard

5.7.6. opsi log files
The opsi log files have the following format:
[Loglevel] Timestamp Message
The log levels are:
0 = nothing (absolute nothing)
1 = essential ("we always need to know")
2 = critical (unexpected errors that may cause a program abort)
3 = error (Errors that will not abort the running program)
4 = warning (you should have a look at this)
5 = notice (Important statements to the program flow)
6 = info (Additional Infos)
7 = debug (important debug messages)
8 = debug2 (a lot more debug information and data)
9 = confidential (passwords and other security relevant data)/var/log/opsi/bootimage
Here you can find the log files of the bootimage from the clients. These files are created as <fqdn>.log.
If the bootimage can not connect to the web service, the log file can be found on the client under /tmp/log. In such a case, there are two ways to get the log file from the client:
-
You have a network connection to the client
Then you can useSCPto get the file from/tmp/log. For Windows you can use for exampleWinSCP. -
You have no network connection to the client
Then a USB stick can help:-
Log in as root with password linux123
-
Insert the USB stick and wait a few seconds
-
Check with
sfdisk -lwhich device the stick is -
mount
-
copy
-
unmount
-
An example session:
#sfdisk -l

/dev/sdb4 0 - 0 0 0 Empty
# mount /dev/sdb1 /mnt
# cp /tmp/log /mnt
#umount /mnt/var/log/opsi/clientconnect
This is the location of the log files of the opsi-client-agent running on the clients.
This is C:\opsi.org\log\opsiclientd.log on the client.
/var/log/opsi/instlog
This is the location of log files of the opsi-winst scripts executed on the clients.
The originals are on the client at C:\opsi.org\log\opsiscript.log
/var/log/opsi/opsiconfd
This is the location of log files of opsiconfd itself as well as log files of the clients.
The files are created as <IP address>.log and if configured in /etc/opsi/opsiconfd.conf, symbolic links for these are created as <fqdn>.log.
/var/log/opsi/opsipxeconfd.log
Log file the opsipxeconfd
which manages the files in the tftp area of the server that are necessary for the PXE boot of the clients.
/var/log/opsi/package.log
Log file of opsi-package-manager.
/var/log/opsi/opsi-package-updater.log
Log file of opsi-package-updater.
tftp log in /var/log/syslog
The log entries of tftpd can be found in /var/log/syslog.
c:\opsi.org\log\opsi_loginblocker.log
Log file of opsi-login-blocker
c:\opsi.org\log\opsiclientd.log
Log file of opsiclientd.
This file is copied to the server at /var/log/opsi/clientconnect/<fqdn>.log when finished.
c:\opsi.org\log\opsi-script.log
Log file of opsi-winst.
This file is copied to the server at /var/log/opsi/instlog/<fqdn.log> when finished.
5.8. Upgrade instructions for opsi-server
As of opsi 4.0, you will find these in the version-specific release notes manuals.
5.9. Special notes on UCS 4.X systems
UCS 4.X requires a DHCP policy to enable a PXE boot from a UCS system.
This policy must be made in the domain policy settings for DHCP boot.
For the bootserver option, you enter the server on which the boot file is located. The boot file name is pxelinux.0. Since this file is located directly in the directory /tftpboot/, the entry will look like this: linux/pxelinux.0
5.10. Scheduling installations
5.10.1. opsi-wakeup-clients, opsi-auto-update and working_window
With the opsi product opsi-auto-update devices can be updated easily and safely without having to set the update for each individual device.
The product opsi-auto-update is described here: Section 8.1.1.19, “opsi-auto-update”.
With the help of cron jobs on the opsi-config-server, the execution of opsi products can be timed and thus e.g. postponed until night.
The prerequisite for this is that the clients can be woken up via wake-on-lan (WOL) or started on a certain time via BIOS.
In order to make the control via cron job as simple and effective as possible, opsi have a builtin-command opsi-wakeup-clients (based on wake_clients_for_setup.py from opsi 4.1).
The parameters of wake_clients_for_setup.py have also been taken over in opsi-wakeup-clients to enable a seemless migration . The only parameter that has changed is --depot-id instead of --depotId.
|
This command has the following tasks:
-
For a specific group of clients
-
a certain group of products is set to
setup -
The selected clients are then woken up via
wake-on-lan -
If the clients were only
sleepingand were not booted, the clients can still be sent the signal to execute a certain event.
The selected clients can be specified either:
-
by specifying a host group, which can for example be created with opsi-configed (see: Section 4.7, “Client selection and hierarchical groups using the tree view”)
--host-group-id HOSTGROUPID -
by specifying an opsi-depot (all clients of the depot are treated)
--depot-Id DEPOTID -
by specifying a file in which the clients are listed
--host-file INPUTFILE
The specification of the selected products which are set to setup is done by specifying a productgroup, which can for example be created with opsi-configed (see: Section 9.17.3.1, “Managing product-groups”)
--product-group-id PRODUCTGROUPID
The event to be triggered is specified via the parameter --event EVENTNAME
The names of groups in opsi must be unique. Regardless of whether it is a hostgroup from the Directory or Groups, or a productgroup: A group name may only appear once.

opsi-wakeup-clients --event=gui_startup --product-group-id=nightly-cron-products --host-group-id=nightly-cron-group-0The clients of the host group nightly-cron-group-0 are selected and the products of the product group nightly-cron-products are set to setup. Then the selected clients are woken up using wake-on-lan, and after a short period the command is sent to them to execute the event gui_startup.
To execute this daily at a certain time, this command must be entered in the crontab of the server.
For example, the command crontab -e can be used (as root).
In the crontab there is a time specified before the command. This consists of 5 parts, of which only the first two interest us: minute, hour.
A crontab in which different client groups are called up during the night is shown in the following example:

In a school, for example, when a student turns on a computer during the day, it should be immediately available and therefore no installations are to be carried out, even if action requests are set. A working_window can be set in the configuration of the opsiclientd for certain events (usually gui_startup).
How this working_window is configured is described here: Section 6.1.3.8, “Working Window”
6. opsi-client
6.1. opsi-client-agent
6.1.1. Overview
In order that the distribution of software does not become unmanageable, a client has to notice that new software packages or updates are available and install them. Any form of user interaction is to be avoided during the installation, so that this can take place unattended and the necessary installations are not interrupted by uncertain users.
With opsi, these requirements are met by an agent on the client:
The so-called opsi-client-agent is installed on the client. This usually checks at the start of the client and before the user logs in, based on configuration information on the opsi-config-server, whether an update should be installed for this client.
If software is to be installed, the script-controlled installation program opsi-script is started. The necessary scripts and software packages are available on a file share, the so-called opsi-depot. During this time, there is no need and no possibility for the user to intervene in the installation process.
To prevent a user from logging on to the system before completing the installation and thus disrupting the installation process, the so-called opsi-login-blocker is also installed, which only allows logon after the installation has been completed.
In order for software packages to be installed without interaction with the program opsi-script, they have to be prepared for this. See the chapter Integrating new software packages in the software distribution of opsi in the opsi-getting-started manual.
6.1.2. Directories of the opsi-client-agent
The opsi-client-agent is installed in %ProgramFiles%\opsi.org\opsi-client-agent.
This directory contains all components of the opsi-client-agent such as opsiclientd, {opsi-notifier}, opsi-script and some libraries. The configuration files and graphical templates of the mentioned programs can also be found here.
The directory %ProgramFiles%\opsi.org\opsi-client-agent is protected against changes by users without administrative privileges.
The directory %ProgramFiles%\opsi.org\opsi-client-agent\opsiclientd contains the configuration file of opsiclientd and can only be accessed with administrative rights.
Furthermore there exists the directory c:\opsi.org.
In this directory a number of variable data are stored, like log files (subdirectory log), packet cache (WAN extension), certificates and some more.
The directory c:\opsi.org can be read only with administrator rights.
6.1.3. The service: opsiclientd
opsiclientd is the basis of the opsi-client-agent. It runs as a service with administrative rights and is started automatically at boot.
The main functions are:
-
Event-based control: There can be reacted to different events on the system. An event is, for example, the start of the operating system.
-
Control via web service: The web service of opsiclientd can be accessed via the network. This interface is used to initiate installations (push) but also for maintenance purposes.
-
Remote configuration: All essential configuration data of opsiclientd can be edited globally or client-specifically via the host parameter.
The opsi-client-agent consists of several components:
-
opsiclientd: The central service of the opsi-client-agent.
-
{opsi-notifier}: Window for information / communication with the user
-
opsi-login-blocker: Blocks the login until the installations are completed.
Installation
As part of a new installation of an operating system via unattended setup with opsi, the opsi-client-agent is automatically installed.
To uninstall the opsi-client-agent, the action request can be set to uninstall.
For installation afterwards or for repair purposes, see chapter Section 6.1.6, “Subsequent installation of the opsi-client-agents”.
opsiclientd
Core component of the opsi-client-agent is the service opsiclientd. This service starts on boot.
It performs the following tasks:
-
while the system is booting and the opsiclientd is waiting for the GUI to come up, the block_login_notifier is started and shows a padlock at the right upper corner of the screen.
-
Getting in action if the configuration event takes place. In case of action the opsiclientd contacts the opsi server via web service (JSON-RPC) and asks for the configuration data and required actions.
The default event is gui_startup which will fire at boot time before user login. -
Creates a named pipe which is used by the opsi-login-blocker to ask via JSON-RPC the opsiclientd when to unblock the login.
-
Starting the {opsi-notifier} for information and interaction with the user.
-
If needed, it connects to the opsi-depot to update the local installation of opsi-script and then starts it to process the action requests (software installation).
opsi notifier
The {opsi-notifier} implements the interaction with the user. It displays status messages and may give the possibility to interact with the process.
There are different situations where the {opsi-notifier} will become active in different ways:
- blocking notifier
-
Indicates that the opsi-login-blocker is blocking
- event notifier
-
Shows information about the current event.
- action notifier
-
Shows state of the event processing
- shutdown notifier
-
Gives information about a requested reboot / shutdown (if
shutdown_warning_time> 0)
|
Names and functionality of the notifier have changed from opsi 4.0 to opsi 4.0.1. The opsi 4.0 event notifier doesn’t exist anymore. The opsi 4.0.1 event notifier equals the opsi 4.0 action notifier. The opsi 4.0.1 action notifier has almost the same functionality as the opsi 4.0 event notifier, but it will only be activated if there is a action request. |
opsi-login-blocker
The opsi-login-blocker for NT5 (Win2K/WinXP) is implemented as a GINA (opsigina.dll).
This GINA waits until the opsiclientd reports, that all product actions are finished or, if the opsiclientd is not reachable, until the connection timeout to the opsiclientd is reached (normally 120 seconds). Then the complete control is forwarded to the next GINA, which is normally the msgina.dll.
The opsi-login-blocker for NT6 (Vista/Win7/Win10) is implemented as a credential provider filter (OpsiLoginBlocker.dll). This credential provider filter blocks all credential providers until the opsiclientd reports, that all product actions are finished or, if the opsiclientd is not reachable, until the connection timeout to the opsiclientd is reached (normally 120 seconds).
Processing sequence
How the opsiclientd works may be configured in many details. To understand these configuration options, it is necessary to understand the processing sequence. Here comes an overview of the work flow of a standard event like the event_gui_startup.
The most important parameters have the following relations:
If there is an error while connecting to the opsi-config-server, the log of this problem cannot be sent to the server. But you may find the log in the local log file opsiclientd.log in the log directory (c:\opsi.org\log\opsiclientd.log) at the client.
|
-
If an event fires, the
event_notifier_commandwill be started.
Now the opsiclientd tries to reach the opsi-config-server using the url address.
If afteruser_cancelable_afterseconds there is still no connection established, so the {opsi-notifier} will enable an Abort button. If no connection could be established inconnection_timeoutseconds, the opsiclientd connection process will be aborted and the event ends with an error message. To avoid a user from aborting, setuser_cancelable_after=connection_timeout. -
After a successful connection to the opsi-config-server, the opsiclientd checks if there are action requests for this client. If there are action requests and the
action_warning_time> 0, theaction_notifier_commandwill be executed.
This is normally the {opsi-notifier}, which shows now the list of action requests for this client foraction_warning_timeseconds.
Is theaction_warning_time= 0 (default) theaction_notifier_commandwill not be executed.
You may allow the user to suspend the process at this time by settingaction_user_cancelable>= 0. The user may suspend the actions up toaction_user_cancelabletimes. Afteraction_user_cancelableaborts in sequence or ifaction_user_cancelable= 0 the user gets no possibility to suspend the actions.
In every case there will be a button which allows the user to start the installations immediately without waiting for the count down ofaction_warning_timeseconds. The messages displayed by the {opsi-notifier} may be configured with the optionsaction_messageoraction_message[lang]. This messages may contain the placeholders%action_user_cancelable%(total number of allowed suspensions) and%action_cancel_counter%(number of suspensions already used by the user).
If the actions are not suspended by the user, theaction_cancel_counterwill reset and the opsi-script will be executed to process the action requests. -
If the opsi-script terminates with a reboot or shutdown request, the
shutdown_notifier_commandwill be executed ifshutdown_warning_time> 0.
The now startingshutdown_notifier_commandshows forshutdown_warning_timeseconds a message saying that the client will be rebooted. Ifshutdown_user_cancelable> 0 the user may suspend the reboot up toshutdown_user_cancelabletimes in sequence. If the user suspends the reboot, theshutdown_notifier_commandwill be restarted aftershutdown_warning_repetition_time. Theshutdown_notifier_commandshows a message which may be configured byshutdown_warning_messageorshutdown_warning_message[lang]. This message may contain the placeholders%shutdown_user_cancelable%(maximum number of allowed suspensions) and%shutdown_cancel_counter%number of suspensions already done by the user).
If the client is rebooted (by the user or the opsi-client-agent) the%shutdown_cancel_counter%will be reset.
| The sequence of event processing and user actions is visualized as a timeline graphic at the info page of the opsiclientd. |
Configuration
The following chapters show how to configure the opsi-client-agent.
Configuration of different events
To meet the requirements of the various different situations in which the opsi-client-agent will become active, a slightly complex configuration is needed. To reduce the complexity, the configuration file uses something like inheritance.
In the opsiclientd configuration section headers like [event_<config-id>] introduce a new event configuration section. An event configuration may be disabled by setting the section option active = false.
There are different types of event configurations (type).
-
There are event configuration templates (type = template).
Event configurations may inherit configurations from another event. In this case the optionsuperpoints to the other event to inherit all parameters from (excluding the parameteractive). These inherited parameters may be overridden by local parameters in the current event section. So an event section needs only those parameters which are different from thesuperevent.
Setting an event toactive = falsedoes not change anything in the inheritance process. -
The other event types are:
-
gui startup
Agui startupevent starts while booting the client and loading the graphical user interface (GUI). It is the most used event and set to active in the default configuration. -
custom
Event configurations of the typecustomare fired by awqlevent. Awqlevent is defined by the correspondingwqlstatement in the event configuration. If thewqlstatement is empty, the event will never be fired, but can be executed from the interactive web interface. -
user login
will be fired at the login of a user -
timer
will be fired allintervalseconds -
sync completed
will be fired if the synchronization of configurations (sync_config_from_server) or products (cache_products) is completed. -
sw on demand
will be fired by the user choosing Start actions now in the software-on-demand web page of the opsiclientd. It will never be fired if software-on-Demand is not used.
-
-
There are Preconditions
Preconditions define special system states (e.g. a user is logged on). In the opsiclientd configuration a section header of the form[precondition_<precondition-id>]starts the declaration of a Precondition. A Precondition is true, if all declared options are true. An option not declared (but possible) is assumed as true.
Possible options for Preconditions are:-
user_logged_in: is true if currently a user is logged on. -
config_cached: is true if the caching of configuration data is completed (see:sync_config_from_server). -
products_cached: is true if the caching of product files is completed (see:cache_products).
-
-
A Precondition can be assigned to an event configuration.
This can be done by giving the precondition in curly brackets at the end of the event configuration section hedaer (e.g.[event_on_demand{user_logged_in}]).
If there is a Precondition in an event configuration header, there also must be a configuration for this event without any precondition. Is there for example an event configurationevent_on_demand{user_logged_in}, there also has to be an event configurationevent_on_demand! The event configuration with the precondition inherits all the parameters from the event configuration without precondition.
If the event is fired, first it will be checked which preconditions are true. If there is no precondition true, the configuration without precondition is used. Is one precondition true, the configuration is used, which is bound to this precondition. If more than one of the preconditions are true, the most specific event configuration is used (which is the configuration with the most matching options).
A small example for a better understanding:
While installing software it may be necessary to reboot the computer. Is there currently a user logged on, you should warn about the pending reboot. This warning should have a timeout and it may make sense to ask the user, if the reboot should be canceled (at the moment).
Is there no user logged on, it makes no sense to ask and wait for an answer. So in this case the reboot should take place immediately.
To handle these different situations, we configure the event_on_demand in the following way:
-
We define a Precondition
user_logged_inwhich comes true if a user is logged on to the system (user_logged_in = true). -
In the default configuration for the event
event_on_demand(without any Precondition) we setshutdown_warning_time = 0(immediate reboot without warning). -
At the configuration
event_on_demand{user_logged_in}we setshutdown_warning_time = 300(warning with 300 seconds timeout).
Working Window
To limit the functionality of an event to a certain time frame a so called working_window can be configured for all events.
| The working_window feature requires opsi-client-agent >= Version 4.1.0.0-39. |
To enable the working_window feature the key working_window has to be added to the configuration of the event. If this key is not present, has no value, or an invalid value it is treated as empty and the event has no time limit.
| Starttime and endtime must be entered in the format hh:mm and separated by a hyphen. Whitespaces between starttime and endtime are not allowed! |
All events support the working_window feature.
Configuration is done by adding the host parameter working_window to the event of your choice.
This can be achived by using the opsi-configed, or via opsi-admin on the opsi-config-server.
The following example shows how to configure a working_window for the event gui_startup using opsi-admin
See Section 6.1.3.13, “Configuration via web service (Host Parameter)” for how to add host parameter using opsi-configed.
Example 1: Adding an empty working_window for the event event_gui_startup globally. The time restriction has to be configured client specific (see example 3).
opsi-admin -d method config_createUnicode opsiclientd.event_gui_startup.working_windowExample 2: Adding a working_window with a timeframe between 20:00 and 07:00 for the event event_gui_startup globally.
opsi-admin -d method config_createUnicode opsiclientd.event_gui_startup.working_window "gui_startup.working_window" "20:00-07:00"Example 3: Client specific configuration of the working_window using a timeframe from 07:00 to 19:00 for the event event_gui_startup.
opsi-admin -d method configState_create opsiclientd.event_gui_startup.working_window "client.domain.de" "07:00-19:00"If the starttime is higher than the endtime the working_window will be valid over the nightly day change (23:59-0:00).
Example during the day (starttime < endtime): working_window=07:00-19:00
Example during the night (starttime > endtime): working_window=20:00-07:00
For the example "working_window=20:00-07:00" the opsiclientd log would look like this:
[5] [<timestamp>] [ event processing gui_startup] Current time 01:02:13.993000 is within the configured working window (20:00-07:00)Configuration of ip version
The opsiclientd supports the IPv4 and IPv6 protocols when connecting to the opsi service. Normally the protocol is selected automatically when the connection is established. But there is also the possibility to configure the protocol version to be used. For this the option "ip_version" can be used in the section "global" of the opsiclientd.conf. Possible values are "4" (use IPv4), "6" (use IPv6) and "auto" (select protocol automatically, default value).
Proxy-Configuration
In the section "global" of the opsiclientd.conf there is the possibility to configure a proxy server. If a proxy is configured, all HTTP and HTTPS connections from opsiclientd will be redirected through this proxy.
# Use a proxy for connecting configservice
# proxy_mode:
# 'system' will try to check the system setting,
# 'static' to use proxyurl from configfile/hostparameter
# proxy_url usage: http://<user>:<password>@<proxy-url>:<proxy-port>
# Example: http://proxyuser:proxypass123@proxy.domain.local:8080
proxy_mode = static
proxy_url =This proxy settings allows also to use a proxyserver, that require authentication. In that case you must define the credentials as shown in the configuration snippet.
| The option proxy_mode is reserved for the value system to use on the system proxy settings. This feature is not implemented yet. Therefore the only option that works at the moment is the static mode. |
Event configuration to control which products will be processed
With this new feature it’s possible over the configuration to control the list of products, that will be processed in Events with product groups:
There are (basically) two ways to use this control:
Blacklisting (excluding):
The option exclude_product_group_ids allows to configure a comma separated list of product Groups. The members of these groups will be excluded from the actual Event. Also if action request is set for this products. This products will be ignored in this event, but the action requests will not be changed.
White listing (including):
The option include_product_group_ids allows to also configure a comma separated list of products Groups. The members of this groups are the only products, that will be processed from the actual event if they have set action requests.
You can use these options globally from the default-Event. From that point this settings will be used in every event. You can also set these options in a special event. If you use the option on event_on_demand, you can control which products will not be installed in push installations, although they have an action request. On normal restart of the client, the products will be installed from gui_startup (default event) at startup. CAUTION: For Clients that work in WAN/VPN-mode you must set this options in sync-event and also in the cacheservice-section, because the cache service have no access to the configuration of main sync-event.
| Product dependencies will not be observed by this feature. That means that you have to observe the process in order to prevent dependency issues. |
Configuration via configuration file
On a 64bit Windows the configuration file is c:\program files (x86)\opsi.org\opsi-client-agent\opsiclientd\opsiclientd.conf.
On a 32bit Windows the configuration file is c:\program files\opsi.org\opsi-client-agent\opsiclientd\opsiclientd.conf.
|
This configuration file is UTF-8 encoded. Any changes using editors which do not support this encoding (e.g. notepad.exe) may destroy any umlaut in this file. |
The configuration written in this file may be changed by different configuration data, which come via web service after a successful connection to the opsi-server.

The opsiclientd configuration can be changed by the host parameter tab at the opsi management interface.
The entries in the host parameter have to be according to the following patterns:
opsiclientd.<name of the section>.<name of the key>
Example:
opsiclientd.event_gui_startup.action_warning_time = 20
set in the configuration file opsiclientd.conf in the section [event_gui_startup] the value of action_warning_time to the value 20.
The following figure shows how to change the serverwide general configure via opsi-configed
Using the context menu you may choose add property to set a new key/value pair.
To delete a server default, please use the opsi-admin tool:
Example:
opsi-admin -d method config_delete "opsiclientd.event_gui_startup.action_warning_time"It is also possible to manipulate these entries client specific via opsi-configed.
To delete a client specific entry, please use the opsi-admin tool:
Example:
@opsi-admin> method configState_delete "opsiclientd.event_gui_startup.action_warning_time" "myclient.uib.local"
Logging
The opsiclientd logs to:
C:\opsi.org\log\opsiclientd.log.
All log information will be transferred to the opsi-config-server via web service. At the server you find these log infos at /var/log/opsi/clientconnect/<ip-or-name-of-the-client>.log. They are presented in the opsi configed at the tab logfiles / client connect.
Every line at the log has the pattern:
[<log level>] [<time stamp>] [message source] message.
There are the following log levels:
# Set the log (verbosity) level # (0 <= log level <= 9) # 0: nothing, 1: essential, 2: critical, 3: errors, 4: warnings, 5: notices # 6: infos, 7: debug messages, 8: more debug messages, 9: passwords

opsiclientd infopage
According to the fact that there are a lot of components of the opsiclientd which work and log at the same time, the log file of the opsiclientd becomes complex.
In order to make it easier to understand how the different components work together, the opsiclientd has an own info page which visualizes the running tasks on a timeline.
You may view this info page at the browser calling the url:
https://<address-of-the-client>:4441/info.html
opsiclientd Bitlocker Suspend Feature
Clients with activated Bitlocker encryption, with manual password entry at boot, prevent the unattended installation of software and patches.
Just like with opsi-script, it is now also possible for reboots triggered by events of opsiclientd to suppress the password input when booting.
| This feature is inevitably associated with a security issue. During this process, the password is written to the hard disk as plain text and is therefore a potential weak point. |
This feature is deactivated by default, in order to activate this option only on selected clients, a standard configuration must be created first:
opsi-admin -d method config_createBool clientconfig.suspend_bitlocker_on_reboot "Suspending Bitlocker at Reboot" falseThe default value false corresponds to the value in the supplied opsiclientd.conf.
To set the host parameter via opsi-admin, the following command has to be executed on the opsi-config-server
(in the example for a client with the opsi-host-Id myclient.domain.de):
opsi-admin -d method configState_create clientconfig.suspend_bitlocker_on_reboot myclient.domain.de true| This option can also be activated on clients that have not activated Bitlocker encryption and this option should not interfere with the operation of the opsiclientd. |
opsi-client-agent remote control
The opsiclientd has its own web service interface which can be used to transmit commands to the opsiclientd. The possible commands can be divided in the following categories:
-
send Messages (Popup)
-
Push installation (start the event on_demand)
-
other maintenance tasks
This can be done on the command line using the tool opsi-admin by calling one of the hostControlSafe_* methods. Calling one of these methods takes the parameter *hostid which:
-
can be
["*"]to send the command to all clients -
can be the name of a client (e.g. "myclient.uib.local")
-
can be a list of client names according to the pattern ["<client1>", "<client2>"]
e.g. ["client1.uib.local", "client2.uib.local"] -
may contain wildcards like
*e.g. "client.*" oder "\*.uib.*"
If a client isn’t reachable (e.g. powered off) you will receive an error message.
Sending popup messages
Using the opsi-configed you may send messages to the clients. Section 4.8.4, “Sending messages (Show popup message)”
At the command line you may do this with the tool opsi-admin:
opsi-admin -d method hostControlSafe_showPopup message *hostidExample:
opsi-admin -d method hostControlSafe_showPopup "This is my message" "myclient.uib.local"Push installations: start the event on demand
The opsi-server may send a command to the client that the client should process the configured action requests immediately. This is done by activating the event on_demand at the client.
This is possible using the opsi-configed and is described in chapter: Push installationen: start the event on demand
From the opsi-server the client can be instructed to execute the product actions.
Executing Events can also be done from the opsi-configed. Section 4.8.3, “Fire opsiclientd event (Push Installation)”
On the command line you may use opsi-admin to fire an event:
opsi-admin -d method hostControlSafe_fireEvent event *hostIdsExample:
opsi-admin -d method hostControlSafe_fireEvent "on_demand" "myclient.uib.local"Additional maintenance tasks (shutdown, reboot,…..)
Using the control server port you may remote control the opsiclientd. In order to do this you have to authenticate yourself at the web service. This could be done either with the local administrator account (with a not empty password) or with the opsi-host-Id (FQDN, client name and DNS Domain name) as user name and the opsi-hostkey as password.
Using the opsi-configed you may choose the menu opsiClient or the context menu in the Clients Tab.
At the command line you also can initiate a client:
shutdown:
opsi-admin -d method hostControlSafe_shutdown *hostIdsreboot:
opsi-admin -d method hostControlSafe_reboot *hostIds6.1.4. Adapting the opsi-client-agent to your Corporate Identity (CI)
Adapting the opsi-client-agent to your Corporate Identity can be important for the user acceptance when rolling out opsi. By adding your corporate logo to the opsi background image, the users feel more familiar with the opsi installation instead of being puzzled by something unknown.
Since opsi-client-agent version 4.0.7.16 all graphic components of the opsi-client-agent (notifier, opsi-script, kiosk-client) are base on the same graphic libraries and may be customized in the same way.
Colors can be configured in three different ways: as symbolic name (clRed), as hexadecimal value ($FF00FF) and as rgb value ((255,0,0)). There is a helper program set allows you simple to choose your colors and get the correct way to write the colors to the configuration file. The program is opsi color chooser.
As background graphic formats you may use a large number of different formats like: .bmp, .png, jpeg and so on. But all these formats are include a number of subformats. So for example is one png file displayed without any problem while an other, different png-file may not displayed in a correct way.
There may also be a difference between the operating system platforms (e.g between Windows and Linux).
There is a helper program set allows you simply to check if a given bitmap file will be displayed correct or not: opsi bitmap viewer.
Elements to be patched: opsi-script
The files to be configured for opsi-script are to be found in the directory /var/lib/opsi/depot/opsi-client-agent/files/opsi/opsi-winst/winstskin:
-
bg.png
This is the opsi-script background image, where during installation text messages and product logos are shown. -
skin.ini
This is the configuration file to specify the position, font and color of text messages during installation.
Elements to be configured: opsiclientd
In the directory
/var/lib/opsi/depot/opsi-client-agent/files/opsi/opsi-notifier/notifier.d
are the files to configure the look of the notifiers.
Each notifier has an background image and a configuration file:
-
block_login.bmp
background image of the login blocker notifier. -
block_login.ini
configuration file of the login blocker notifier. -
event.bmp
background image of the server connection event notifier. -
event.ini
configuration file of the server connection event notifier. -
action.bmp
background image of the action notifier (software installation). -
action.ini
configuration file of the action notifier. -
shutdown.bmp
background image of the shutdown/reboot action notifier. -
shutdown.ini
configuration file of the shutdown/reboot action notifier. -
popup.bmp
background image of the popup message notifier. -
popup.ini
configuration file of the popup message notifier. -
userlogin.bmp
background image of the user login event notifier. -
userlogin.ini
configuration file of the user login event notifier.
Elements to be configured: kioskclient
| This chapter is only relevant for opsi-client-agent versions <= 4.1.0.0. Since 4.1.1.0 the kiosk is outsourced and available as opsi-client-kiosk package. For description of the opsi-client-kiosk see: Section 9.17, “opsi Software On Demand - opsi-client-kiosk (free)” |
The Headers list from the Main window (1) is customizable to the desire of the client. To that, there are two files which play a roll:
The header of the main windows (1) is customizable.
There are three files which are relevant:
-
header.png -
logo.png -
opsiclientkiosk.ini
The opsiclientkiosk.png holds the picture which will be loaded in this area.
The opsiclientkiosk.ini defines the text and its representation which will be shown in this area.
Example:
[TitleLabel] Text= Opsi Client Kiosk FontName = Arial FontSize = 15 FontColor = clWhite FontBold = false FontItalic = false FontUnderline = false [Tile] Width = 220 Height = 200 Color = clCream FontName = Arial FontSize = 12 FontColor = clBlack FontBold = false FontItalic = false FontUnderline = false [TileRadio] Fontsize = 10 None_color = clBlack Uninstall_color = clRed Setup_color = clGreen
You will find templates for these files under /var/lib/opsi/depot/opsi-client-kiosk/files/app/ock_custom/skin
or C:\Program Files(x86)\opsi.org\opsi-client-agent\opsiclientkiosk\ock_custom\skin
The icon used in each case can be changed by placing a kiosk.ico file under /var/lib/opsi/depot/opsi-client-kiosk/files/app/ock_custom/skin.
Protect your CI changes from updates: the custom directory
(available since opsi-client-agent version 4.0.2.3)
The custom directory can be used to protect your configuration changes during opsi-client-agent updates: (/var/lib/opsi/depot/opsi-client-agent/files/opsi/custom). During server updates of opsi-client-agent the whole custom directory will be saved and restored after the update, so that your custom changes will persist.
-
custom/config.ini
Values from this config file override values from the defaultcfg/config.ini. Except of the values forpckeyandbootmode, which never are picked from that file. Add to your custom config file only those values, that are different from the default settings. -
custom/winstskin/*.*
All the files from this directory will be copied to the clientsC:\Program Files (x86)\opsi.org\opsi-client-agent\custom\winstskindirectory during installation of the opsi-client-agent on the client. Thiswinstskindirectory, if it exists, since opsi-script Version 4.11.3.4. is the preferred one. It must contain all required winstskin files and configurations, for the content of the default directory is ignored. -
custom/notifier/*.*
All the files from this directory will be copied to the clientsC:\Program Files (x86)\opsi.org\opsi-client-agent\notifierdirectory during installation of the opsi-client-agent and overwrite the files from the server sidefiles/opsi/dist/notifier/directory. -
custom/opsiclientd.conf
If it exists, thecustom/opsiclientd.confwill be copied to the clientsC:\Program Files (x86)\opsi.org\opsi-client-agent\opsiclientddirectory during installation of the opsi-client-agent and overwrites the default opsiclientd.conf from the server sidefiles/opsi/dist/opsiclientd/directory. So the custom opsiclientd.conf must contain all the required configuration entries.
Attention:
Using a customopsiclientd.confis not recommended. To customize your client configuration, use the host parameter configuration for single features as described in the opsi-client-agent chapter. Using a customopsiclientd.confis applicable for very complex configurations only. By using a customopsiclientd.conf, after each update of opsi-client-agent it is required to check the server default filefiles/opsi/dist/opsiclientd/opsiclientd.conffor changes to be patched to your customopsiclientd.conf.
So: hands off this feature, unless you really know what you are doing!
A subsequent cleanup of the file access rights helps to avoid errors:
opsi-setup --set-rights /var/lib/opsi/depot/opsi-client-agent6.1.5. Blocking the user login with the opsi-Loginblocker
To prevent a user from logging into the system before the installation is complete, the opsi-login-blocker can be installed. This will not allow access to the login until the installation process is complete.
Whether the opsi-login-blocker is installed or activated during the opsi-client-agent installation,
can be configured via the product property loginblockerstart.
opsi loginblocker at Windows 2000 to XP (NT 5)
The opsi-login-blocker is implemented as the Gina opsigina.dll. Gina means Graphical Identification and Authentication and is the official Microsoft hook to manipulate the login process.
If you already have a special Gina-DLL installed, which is different from the original Microsoft msgina.dll (e.g. Novell nwgina.dll), you should not install the opsi-login-blocker without consulting uib or https://forum.opsi.org. It is possible to chain different gina.dll’s, but therefore the installation has to be customized. Proper chaining of Gina DLLs is a quite critical task and might result in a locked up computer if done improperly.
Whether the opsi-login-blocker is installed or not is configured by the switch LoginBlockerStart=on/off in section [opsi-client-agent-install] of the client configuration.
opsi loginblocker at NT 6 (Vista/Win7/Win10)
The opsi-login-blocker at Vista is implemented as a credential provider filter. It blocks all credential providers until the release by the opsiclientd or timeout.
6.1.6. Subsequent installation of the opsi-client-agents
The information about the Subsequent installation of the opsi-client-agent you will find in the opsi-getting-started manual (Chapter First Steps).
Installation of the opsi-client-agent from a master image or as exe
In order to install the opsi-client-agent from a prepared (sysprep) masterimage, the opsi-client-agent has to be (re)installed while the clone awakes and get a new personality.
To do this use the following steps:
-
Copy from the share
opsi_depotthe complete content of the directoryopsi-client-agentin a temporary directory on the master. -
Edit there the file
files\opsi\cfg\config.ini:-
In section
[installation]set forservice_user=the login name of a user that is member of the opsiadmin group.. -
NOT RECOMMENDED: In section
[installation]set forservice_password=the uncoded password of this user. Better: -
In section
[installation]set forservice_hidden_password=the base64 encoded password of this user. For encoding of the pawword you may use the opsi-script functionbase64EncodeStr(<string>)or a online service like http://www.base64encode.org/
Ifservice_hidden_password=has any value the keyservice_password=will be ignored. -
In section
[opsiclientd]set forconfig_service.url =the web service address of your opsi-config-server (e.g.https://192.168.1.10:4447/rpc)
-
-
Make sure that the script
silent_setup.cmdfrom the temporary directory is called after the clone has its new personality. -
After the call of
silent_setup.cmdis finished, the temporary directory should be deleted.
If you like you may pack the temporary directory to a self extracting exe with final program start using a tool like filzip.
6.1.7. The Systray Program of the opsi-client-agent
The systray program of the opsi-client-agent focuses on the following targets:
-
Notifying the user in regular (and configurable) Intervals on pending Installations. (Optional)
-
Notifying the user on pending Installations on demand by using the context menu.
-
Possibility for the user to start the installations.
Controlling the opsi systray program via the opsi-client-agent product properties:
-
systray_install
(true/false) Install the opsi systray program ?
Default =false -
systray_check_interval
Interval in minutes to check for pending action requests.
Default=180(Small values here give heavy load to the server)
The value0means: no checks at all.. -
systray_request_notify_format
Format of action request notification.
Possible Values:
"productid : request", "productname : request", "productname productversion : request"
default: "productname : request"
Logs of the opsi systray program:
The program logs to %Appdata%\opsi.org\log. That is the opsi.org\log directory in the Appdata directory of the loggedin user.
For Example:
C:\Users\<username>\AppData\Roaming\opsi.org\log\

7.1. Introduction
Opsi is a powerful tool for the administration of many clients.
According to that fact, the opsi-server has to be in the focus of security considerations.
If you control the opsi-server, you are in control of all the clients, that are connecting to that opsi-server.
How much time and money you should spend for hardening your opsi-server, depends on your needs regarding security and the operational environment for using opsi. So for example an opsi-server in the cloud is more endangered than an opsi-server in a secured network.
In the following chapter we have collected the most important issues and problems.
At this point we say thank you to all customers and users which informed us about security problems and helped us to improve the security of the opsi system. If you find any security problem, please inform us (info@uib.de) before disclosing the security vulnerability in public.
7.2. Stay tuned
Information about security relevant updates and tasks are published at
the news area at the opsi forum:
https://forum.opsi.org/viewforum.php?f=10
7.3. General server security
The opsi software cannot be more secure than the underlying operating system. So please make sure to update your server with the security updates of your Linux distribution. This has to be done not only for the opsi-config-server, but also for all the opsi-depot-server.
It may help you to install programs which inform you by email if there are new updates available.
- Debian, Ubuntu
-
apticron
- RHEL, CentOS
-
yum-updatesd
There are a lot of possibilities to enhance the security of your Linux server. But this is not the task of this manual.
We would be happy to help you with this task as part of a support contract.
7.4. Client authentication at the server
The client authenticates itself using the FQDN as username and the opsi-host-key as password.
The opsi-host-key is stored at the client in the file:
%programfiles%\opsi.org\opsi-client-agent\opsiclientd\opsiclientd.conf
which is readable with administrative privileges only.
The opsi-host-key is stored at the server in the used backend (e.g at /etc/opsi/pckeys).
In addition to this authentication, you may tell the opsiconfd to check if the client ip address matches the given FQDN. To activate this check, set in /etc/opsi/opsiconfd.conf:
verify ip = trueand restart opsiconfd:
systemctl restart opsiconfd.service| Do not use this feature if you are not really sure, that your name resolution works properly in both directions for all clients. |
7.5. Verification of the server identity
Since opsi 4.2, the trustworthiness of the opsi-server can be ensured using standard TLS methods.
Each opsi-config-server maintains a Certificate Authority (CA), the opsi CA. This CA is automatically managed by the opsi-config-server. Each opsi-server, also the opsi-depot-server receive a TLS certificate from the opsi-config-server, which is signed by this CA. These certificates are also automatically created, distributed and updated as needed. Any client that trusts the opsi CA also trusts these server certificates.
The certificate of the opsi CA can be retrieved from any opsi-server at the URL https://<server-address>:4447/ssl/opsi-ca-cert.pem. More information about the CA and the server certificate is available on the opsi-servers admin page (https://<server-address>:4447/admin).
If a opsi-client-agent connects to a opsi-config-server, it automatically retrieves the opsi CA and stores it at c:\opsi.org\tls\opsi-ca-cert.pem or /etc/opsi-client-agent/tls/opsi-ca-cert.pem. However, this only happens under the condition that either no opsi CA is stored there yet or a secure, verified connection to the opsi-config-server is established.
To enable verification of server connections, the following option is set in opsiclientd.conf, section [global]:
verify_server_cert = trueIt is advisable not to make this change manually, but to create a corresponding host parameter on the server. For example, the boolean host parameter opsiclientd.global.verify_server_cert with default value false is created via opsi-configed. This also works via opsi-admin:
opsi-admin -d method config_createBool opsiclientd.global.verify_server_cert verify_server_cert falseThis parameter can then be set to true on a client-specific basis, or it can be enabled globally.
This will enable server verification.
If webdav is used as clientconfig.depot.protocol, the opsi-depot-server will also be verified accordingly.
| Once verification is enabled, the client will refuse connections to servers without a valid certificate. So it should be ensured in advance that the mechanism works as desired. |
Additionally it is possible to store the opsi CA in the certificate store of the operating system.
Then the operating system as well as all applications which use this certificate store trust the opsi CA and the certificates of the opsi-server.
This is also a prerequisite to mount an opsi repository via WevDAV.
The associated boolean configuration is opsiclientd.global.install_opsi_ca_into_os_store.
If this is enabled, the opsi-client-agent automatically injects the opsi CA into the certificate store of the operating system.
7.5.1. Problem solving
If it comes to the situation that a client does not accept the server certificate of the opsi-config-servers anymore because of problems with the opsi CA, the client is no longer manageable by the normal opsi mechanisms.
In this case there are several ways to solve the problem:
7.5.2. Delete the opsi CA on the client.
The file opsi-ca-cert.pem is deleted on the client. The next time the client connects to the opsi-config-server, the opsi-client-agent will retrieve the opsi CA again.
7.5.3. Replacing the opsi CA via the opsi-client-agent’s control server.
The opsi CA can be updated via the control server API of the opsi-client-agent. The RPC updateOpsiCaCert is used for this purpose. Via the parameter ca_cert_pem the content of the opsi CA certificate is passed in PEM format as a string.
7.5.4. Via a temporary server certificate of uib GmbH.
In addition to the opsi CA of the respective environment, a opsi-client-agent also trusts the uib opsi CA if the corresponding configuration opsiclientd.global.trust_uib_opsi_ca is set to true. The uib opsi CA is managed by uib GmbH. The uib GmbH is therefore able to generate a temporary valid server certificate for the opsi-config-server. This certificate can then be installed on the opsi-config-server of the environment. The opsi-client-agent then reconnects and automatically retrieves the opsi CA of that environment. When this process has taken place on all affected clients, the temporary certificate can be removed again.
7.6. Authentication at the control server of the client
The opsiclientd provides a web service interface, which allows remote control of the opsiclientd and thus remote control of the client.
In order to access this interface authentication is required. You may authenticate as a local administrator with a not empty password, or with an empty user name and the opsi-host-key as password.
7.6.1. The opsi-client-agent kiosk api
The opsiclientd kiosk API allows access from localhost without any authentication. If the software-on-demand function (opsi-client-kiosk) is not in use, this API can be disabled completely.
To do this, the following parameter must be set in the opsiclientd.conf in the section [control_server]:
verify_server_cert_by_ca = true7.7. Configuration of allowed networks
By default, the opsi service accepts connection from any ip addresses.
To improve security, you may configure a list of ip networks which are allowed to connect.
For this purpose there is the opsiconfd option networks.
A configuration like e.g.
networks = [192.168.1.0/24, 10.1.0.0/16]would limit access to the networks 192.168.1.0/24 and 10.1.0.0/16.
7.8. Configuration of allowed admin networks
The idea of an admin network is to ban any administrative access from the standard production network and allow these accesses only from a special admin network.
With opsi all opsi-clients need restricted access to the opsi web service, which allows them to read and change their own data. Administrative access with further privileges is granted to members of the unix group opsiadmin only.
If you configure an admin-networks parameter, all administrative accesses are restricted to these network(s).
Setting the option admin-networks at the /etc/opsi/opsiconfd.conf will restrict the administrative access to the opsiconfd to connections coming from the specified network address(es).
You may define multiple addresses.
Non administrative access may also come from other networks.
The default is:
admin-networks = [0.0.0.0/0, ::/0]and allows administrative access from all networks.
A configuration like e.g.
admin networks = [127.0.0.1/32, 10.1.1.0/24]restricts administrative access to the server itself and to the network 10.1.1.0/24.
7.9. Configuration Lock out clients and unlock them again.
If a client tries to log in to the server too often without success, it will be locked out for a certain time. There are three configuration options for this:
max-auth-failures specifies after how many failed attempts a client will be locked out.
The default is:
max-auth-failures = 10The option auth-failures-interval determines in which time period the failures specified with max-auth-failures must occur,
that a cleint is blocked. The specification is in seconds.
Default:
auth-failures-interval = 120The third option client-block-time specifies how long a client will be blocked if it gets above the number of attempts (auth-failures-interval) in the time period (max-auth-failures). This specification is also in seconds.
Here is the default:
client-block-time = 120The information about the error attempts and which clients are blocked is stored in Redis. There are two Redis keys for this:
-
opsiconfd:stats:client:failed_auth:<client ip> Number of failed attempts of the client (Redis Time Series)
-
opsiconfd:stats:client:blocked:<client ip>: Will be created when the client is blocked and contains the value "True" (Type: stirng)
To release the clients manually you can use the admin page https://<opsi-server>:4447/admin (see Section 5.3.4.1, “In the browser: opsi admin page”).
7.10. The user pcpatch
With opsi 4 the user pcpatch is used just by the opsi-client-agent to mount the depot share (opsi_depot).
Excepions are the products:
-
opsi-wim-captureandopsi-local-image-capturewhich use pcpatch to mount the shareopsi_depot_rw -
opsi-clonezillawich use pcpatch to mount the shareopsi_images
The password of the user pcpatch is usually stored and transmitted encrypted. Under special circumstances it might be possible to catch the clear password. To reduce risks arising from that, you should do the following:
Deny for the user pcpatch the access to all other shares than the opsi_depot share. You should do this by adding the following entry to all share definitions (besides the opsi_depot) at the /etc/samba/smb.conf:
invalid users = root pcpatchAlternative
At the /etc/samba/smb.conf restrict privileges for the user pcpatch to global read only by setting in the [global] section:
read list = pcpatch
For the products opsi-wim-capture and opsi-local-image-capture the share opsi_depot_rw must have write permission for pcpatch. For the product opsi-clonezilla the share opsi_images must have write permission for pcpatch
|
As an additional task you should frequently change the password of the user pcpatch. You may set the password to a random string which no one knows (besides opsi). You may do this by calling the following command e.g by a cronjob:
opsi-admin -d task setPcpatchPassword $(< /dev/urandom tr -dc _A-Z-a-z-0-9 | head -c16)If you are not using netboot products that require the possibility to login as user pcpatch you can disable the login for that user.
To do so please change the shell of the user pcpatch to /bin/false in the file /etc/passwd.
Since opsi 4.1 the default shell for the user pcpatch is /bin/false. You only need to take action if the system was set up using an earlier version.
7.11. Webservice access limitations
The file /etc/opsi/backendManager/acl.conf can be used to limit the access
to specified methods and attributes of the returned values.
The limitation affects the base methods of the webservice. For those a restriction of users or groups and allowed attributes can be established.
The access should be limited to the used methods.
If it is not clear what methods are being used one can refer to the output of
opsiconfd about the accessed methods. This is logged to /var/log/opsi/opsiconfd/opsiconfd.log in case of a stop or restart.
More information about the webservice can be found at Section 5.4.1, “object oriented methods”.
7.12. Change the bootimage root password
The root password of the opsi linux bootimage is linux123 by default. You may like to change this for security reasons. How to do this is desribed here: Section 8.2.1, “Parameteters for the opsi linux boot image”
8. opsi products
8.1. Localboot products: automatic software distribution with opsi
Localboot products are all products that are installed by the opsi-client-agent after the computer started the installed OS. This is in contrast to the netboot products described below Section 8.2, “Netboot products”.
8.1.1. opsi standard products
The following localboot products are part of the default installation of opsi.
opsi-client-agent
The opsi-client-agent is the client agent of opsi and is described in detail above: see chapter Section 6.1, “opsi-client-agent”.
opsi-winst
The product opsi-winst is a special case. It contains the current opsi-winst. This does not have to be set to setup to update. Rather, part of the opsi-client-agent checks each time it is started whether a different version of the opsi-winst is available and fetches it if this is the case.
javavm: Java Runtime Environment
The product javavm provides the Java Runtime Environment for the clients, which is required for opsi-configed.
opsi-configed
The opsi graphical management interface packaged as application For Windows and Linux. See also chapter: Chapter 4, opsi-Management GUI: opsi-configed
jedit
Java based editor with syntax highlighting for opsi-winst scripts.
swaudit + hwaudit: Products for hard- and software-audit
The hwaudit and swaudit products are used for hardware and software inventory. The hardware data is collected via WMI and reported back to the server via the opsi web service. For the software inventory the information is taken from the registry key (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall)and reported back to the server via the opsi web service.
opsi-template
Template for creating your own opsi scripts. You can extract the template with:
opsi-package-manager -x opsi-template_<version>.opsior rename it at the same time:
opsi-package-manager -x opsi-template_<version>.opsi --new-product-id myprodSee also the opsi-getting-started manual.
opsi-template-with-admin
Template for creating your own opsi scripts. You can extract the template with:
opsi-package-manager -x opsi-template-with-admin_<version>.opsior rename it at the same time:

opsi-logviewer
Text viewer with selection for log levels and events.
For Windows and Linux.
-
The opsi-logviewer tool created by uib now also opens files that are compressed in the archive formats zip or gzip. This means that log files that are sent as an archive can be viewed directly. (If an archive contains several files, the contents are of all files are appended.)
-
The setup script has been expanded to include Linux support so that opsi-logviewer can also be installed automatically on a Linux client.
-
The new before-dependency on javavm ensures the this program can be started (because javavm copies the javaw.exe into the system directory)

Configures various Windows 10 settings such as lock screen, hibernation boot, sending telemetry and update behavior.
Version 4.0.7 added new options.
-
change_power_plan changes the power management profile.
-
config_updates allows you to change the source of the updates. The updates are then downloaded either directly from Microsoft servers, a local peer-to-peer network or a peer-to-peer network from the Internet. The disable option is meanwhile moved into a separate property called disable_updates.
-
defer_upgrade postpones updates and upgrades. Updates can be postponed by four weeks and upgrades by eight months. It should be noted that security-relevant updates are installed despite the defer option. However, feature updates are not installed.
-
disable_advertising_id deactivates the so-called Advertising ID. This stores data about the browser history in order to display user-specific advertising.
-
disable_cortana deactivates the Cortana voice assistant. This collects various data about input and transfers this data to Microsoft servers.
-
disable_customer_experience disables collecting data related to application usage data.

-
disable_lock_screen disables the lock screen.
-
disable_mac deactivates a service that collects data about currently logged in users and transfers it to Microsoft.
-
disable_mrt deactivates the use of the Malware Removal Tool, MRT for short. This service scans existing files on the computer’s hard drive at regular intervals and compares them with a list of potentially dangerous software.
-
disable_onedrive_sync disables the OneDrive file synchronization.
-
disable_sending_feedback makes it possible to influence the transfer of data to Microsoft in the event of application crashes.
-
disable_smbv1 disables the SMB v1 protocol.
-
disable_telemetry makes it possible to limit the amount of data collected. A lot of data is transferred as standard. If the property is set to true, Windows is set so that only security-relevant data is transferred. This is the lowest level. This security level can only be set in the Windows 10 Enterprise and LTSB version. In the other versions of Windows 10, the next lowest level is applied, Basic.
-
disable_updates blocks connections to Microsoft update sources when set to true. Setting the property to false enables these connections again.
-
disable_wifi_sense deactivates the service called Wifi Sense. This service enables saved WLAN configurations to be shared with contacts.
-
flashplayer_autorun There is a security vulnerablility in Windows 10 with the Adobe Flashplayer. It is recommended to deactivate the autorun feature of the flash player. With false the Flashplayer is no longer started.
-
online_search Online results are also provided for every search using the integrated search bar in the taskbar. true enables such an online search, false disables it.

opsi-auto-update
opsi-auto-update is a product to simplify the maintenance of the clients.
| opsi-auto-update is not for clients running the WAN-extension |
In essence, this product can be used to ensure that the installed products are up to date.
The product sets all installed products,
whose version is not identical to that on the server,
for the client to setup.
Properties for managing exceptions:
-
name:

Special properties for local-image / vhd-reset:
See also: Section 9.9, “opsi vhd reset”
See also: Section 9.8, “opsi local image”
-
name:
do_cleanup-
description: If false: skip restore before update
This property is ignored if it is not a vhd or local image installation.
For a vhd installation, do_cleanup=true executesopsi-vhd-controlbefore the updates, thereby discarding all changes and restoring the saved state.
For a local-image installation, do_cleanup=true executesopsi-local-image-restorebefore the updates, thereby discarding all changes and restoring the saved state.
In both cases, information about action requests is also discarded. In order to be able to add or remove products during a run ofopsi-auto-update, there are the following two properties.
-
-
name:
products_to_install-
description: Which opsi product(s) should be installed via update ? (List will be cleared after run)
List of products which are set to setup during the opsi-auto-update run. If the products have been installed successfully, they will be removed from this list.
-
-
name:
products_to_uninstall-
description: Which opsi product(s) should be uninstalled via update ? (List will be cleared after run)
List of products which are set to uninstall during the opsi-auto-update run. If the products have been uninstalled successfully, they will be removed from this list.
-
-
name:
do_merge-
description: If false: skip backup after update
This property is ignored if it is not a vhd or local image installation.
For a vhd installation, do_cleanup=true executesopsi-vhd-controlwithupgrade=trueafter the updates and thus all changes are saved.
For a local-image installation, do_cleanup=true executesopsi-local-image-backupafter the updates and thus all changes are saved.
-
Properties for debugging:
-
name:
disabled
This property is for debugging purposes.
If true, the product does not execute any actions.
Default = false -
name:
rebootflag
Please do not change during the run. This should be 0 before starting. -
name:
stop_after_step
This property is for debugging purposes.
If not 0 then this is the number of reboots after which to stop. Default = 0
The opsi-auto-update product has a very low priority (-97),
which is even less than that of opsi-vhd-control.
The opsi-auto-update product can be combined well with a cron job that executes opsi-wakeup-clients.
(opsi-wakeup-clients is part of the opsi-utils package)
For details see here: Section 5.10.1, “opsi-wakeup-clients, opsi-auto-update and working_window”
8.1.2. Manipulating the installation sequence by priorities and dependencies
Since opsi 4.0, the installation order is determined by the opsi-server taking into account product dependencies and product priorities.
-
Product dependencies
Defines dependencies and the necessary installation order between opsi-packages. A typical example is the dependency of Java programs on the Java Runtime Environment (javavm). -
Product priorities
Priorities are used to push certain packages forward or backward in the order of installation. It makes sense to install service packs and patches first and a software inventory at the end of an installation sequence.
Product priorities are numbers between 100 and -100 (0 is the default)
There are different possibilities how these two factors are used to determine the installation order. Therefore, opsi provides two algorithms.
Switch between these algorithms can be done either:
using opsi-configed, in the server configuration
or on the command line with the following command:
opsi-setup --edit-config-defaults
Algorithm1: product dependency before priority (default)
With this algorithm, the products are first sorted based on their priorities and then re-sorted based on the product dependencies. This of course allows a product with a very low priority to be pushed far forward because it is required by a product other than required before. On the other hand, it prevents installation problems due to unresolved product dependencies.
Algorithm 1 ensures that the installation order is constant, regardless of how many products are set to setup. This order corresponds to the order which is shown in configed when the products are sorted according to the position column.
This ensures that if a setup script is only interrupted with "ExitWindows /immediateReboot", the processing of the interrupted script is continued immediately after the reboot.
Algorithm2: product priority before dependency
This algorithm is based on the idea that in practice, there are essentially three priority classes:
-
Products to be installed first such as OS patches and drivers that bring the PC to a standard state. Is realized by assigning a high priority (maximum +100).
-
"Normal" products that install applications (default priority 0).
-
Products that should be installed last, e.g. software inventory control. Realized by assigning a low priority (lowest possible -100).
Product dependencies are only resolved within a priority class. This ensures that products with a high priority are actually installed at the beginning. Cross-priority product dependencies are not taken into account or give a warning. It is therefore important to note when packaging that product dependencies are only defined within one priority class.
The product dependencies are interpreted here in such a way that with "normal" products they automatically lead to a consistent order that takes all dependencies into account. If contradictory (circular) dependencies have been defined, an error is displayed.
In the case of products with high priorities that are essential for setup of the computer, however, the administrator should set the exact order by hand - similar to, for example, Unix start-up scripts - by assigning a specific priority between +100 and +1 for each product according to the desired order. The same applies to the final products with low priorities.
Defining product priorities and dependencies
Priorities and product dependencies belong to the metadata of an opsi-product. You will be asked for these when creating a product with the command opsi-newprod.
This metadata is stored in the control file of the product and can be edited there. After a change in the control file, the product must be repacked and installed again.
See also the chapter Creating an opsi product package in the opsi-getting-started manual.
8.1.3. Integration of new software packages into the opsi software deployment.
Instructions for integrating your own software can be found in the opsi-getting-started manual.
8.2. Netboot products
8.2.1. Parameteters for the opsi linux boot image
The opsi-linux-bootimage has some parameters which may be used to change the behaviour of the bootimage. You will try this if the opsi-linux-bootimages doesn’t run properly with the standard parameters on your hardware (e.g. black screen).
You may change these standard parameters by the opsi-configed choosing the Tab Hostparameter and use there the entry opsi-linux-bootimage.append.
Typical values are (may be combined):
-
acpi=off -
noapic -
irqpoll -
reboot=bios
For AMD Ryzen 2XXX Prozessoren we recommend to use the parameters:
-
mem=2G -
ramdisk_size=2097152
AMD Ryzen 3XXX additionally need the parameter
-
nomodeset
to correctly display the bootimage.
-
dhclienttimeout=SECONDS
sets the value timeout in /etc/opsi/dhclient.conf within the opsi-linu-bootimage (default 30 seconds).
An other important default is the password of the root user within the opsi-linux-bootimage. This password is linux123 by default and you should change this for security reasons.
To do this change the opsi-linux-bootimage.append entry at the server-configuration.
The option you have to change is pwh (password hash). As the value to this option you have to give a new password as a hash, which will be loaded to the /etc/shadow during the boot process.
The best way to get the correct password hash is to login via ssh to your bootimage:
ssh root@<client.domain.tld>The old password is linux123.
Now set a new password for root:
passwdGet the new hash
grep root /etc/shadowThe output should look like this:
root:$6$344YXKIT$D4RPZfHMmv8e1/i5nNkOFaRN2oYNobCEjCHnkehiEFA7NdkDW9KF496OHBmyHHq0kD2FBLHZoTdr5YoDlIoWz/:14803:0:99999:7:::Now copy from after the first colon until to the second colon and use this as value for pwh.
So the option for opsi-linux-bootimage.append may be:
pwh=$6$344YXKIT$D4RPZfHMmv8e1/i5nNkOFaRN2oYNobCEjCHnkehiEFA7NdkDW9KF496OHBmyHHq0kD2FBLHZoTdr5YoDlIoWz/One can execute a pythin script before the execution of the desired netboot product. Therefore the bootimage append supports two parameter:
-
pre-execute -
pre-script
In addition these parameter require an address with the script. This can be a http:// or tftp:// address. Please refer to the following example:
-
tftp://172.16.166/linux/test.py
When using tftp please keep in mind that the default port 69 is used.

At the next reboot, the client detects (via PXE-Bootprom) the re-installation request and loads the boot image from the opsi-server.
Using CD-Boot: * The client boots the boot image from the opsi-client-boot-cd. *The boot image starts and asks for confirmation to proceed with the re-installation. This is the only interactive question. After confirming this, the installation proceeds without any further request for interaction. * The bootimage formats and partitions the hard disk. * The bootimage copies the required installation files and configuration information from the opsi-server to the client and initiates a reboot. * Windows Installation: After the reboot the client installs the OS according to the provided configuration information without any interaction. * Linux Installation: By default the Linux Netboot products initiate a kexec command from within the bootimage and directly jumpt to the distribution installaer. * Next the opsi-client-agent is installed as the opsi installer for automated software distribution. * The automated software distribution then installs all the software packages as defined in the client’s configuration.
Preconditions
The client PC has to be equipped with a bootable network controller. Most recent network controllers provide this functionality (PXE boot). Also recent network controllers which are integrated on the PC’s main board. The PXE software, which is stored in the bootprom of the network controller, controls the boot process via network according to the BIOS boot device sequence. Usually the boot sequence has to be set in the BIOS, network-boot has to be the first boot device. If there is no possibility to use PXE you may boot from the opsi-client-bootcd.
The opsi installation package for the OS to be installed needs to be provided on the depot server. In the following we assume Windows 10 to be the OS to install.
PC-client boots via the network
The PXE firmware gets activated at startup of the PC. Part of the PXE implementation is a DHCP client.
At first the PC only knows its hardware Ethernet address (MAC), consisting of six two-digit HEX characters.
The firmware initiates a DHCPDISCOVER broadcast: “I need an IP address, who is my DHCP-Server?“
The DHCP-Server offers an address (DHCPOFFER).
DHCPREQUEST is the response of the client to the server if the IP address is accepted. (This is not an obsolete step as there could be more than one server in the network.)
The server sends a DHCPACK to acknowledge the request. The information is sent to the client again.
You can watch this process on the display, for the PXE-BOOTPROM displays some firmware information and its CLIENT MAC ADDR. The rotating pipe-symbol is displayed during the request. When an offer was made it is replaced by an \ and you get the transmitted information (CLIENT IP, MASK, DHCP IP, GATEWAY IP). A short while later you should get a response like this: My IP ADDRESS SEEMS TO BE …….
This process makes the PC a regular, fully configured member of the network. The next step is to load the boot file (bootimage) given in the configuration information.
Loading pxelinux
The bootimage is loaded via trivial file transfer protocol (tftp). The displayed message is „LOADING“. tftp is a rather old and simple protocol to transfer files without authentication. In fact, all data available via tftp is available to everyone in the network. Therefore the tftp access is limited to one directory, which is usually /tftpboot. This directory is specified in x/inetd (internet daemon, /etc/inetd.conf), which will start the tftp daemon tftpd if requested. The start command as noted in inetd.conf is something like
tftpd -p -u tftp -s /tftpboot
The PXE boot-process is a multi-stage process:
Stage 1 is to load and start the file submitted as part of the address discovery process (usually /tftpboot/linux/pxelinux.0).
The program pxelinux.0 then looks for configuration and boot information in /tftpboot/linux/pxelinux.cfg. It first looks for a PC specific file with a name based on the hardware ethernet address (MAC) of the network controller with a leading 01. The filename for the controller with the hardware ethernet address 00:0C:29:11:6B:D2 would be 01-00-0c-29-11-6b-d2. If the file is not found, pxelinux.0 will start to shorten the filename (starting at the end) to obtain a match. If this process ends without result, the file default will be loaded. This file only contains the instruction to boot from the local hard disk. In this case the PC won’t install anything and will just start the current OS from hard disk.
To initiate the re-installation of a certain PC, a loadable file is prepared for the program pxelinux.0. In order to do so, the opsipxeconfd creates a PC custom file in /tftpboot/linux/pxelinux.cfg. Part of this file is the command to load the installation boot image. Also this file contains the client key to decrypt the pcpatch password. This file is created as a named pipe and therefore disappears after being read once. More details about this in the chapter on security of file shares.
Based on the information the pxelinux.0 got from the named pipe, the actual bootimage is loaded from the opsi depot server via tftp. The bootimage is based on a linux kernel (/tftpboot/linux/install) within an appropriate initrd file system (/tftpboot/linux/miniroot.bz2).
Boot from CD
Similar to the tftp boot via PXE-bootprom, the installation boot image can be booted from the opsi bootcd.
This might be recommended under the following conditions:
-
the client has no PXE bootprom;
-
there is no dhcp;
-
there is a dhcp but it isn’t allowed to configure any client data and the hardware addresses of the clients are unknown;
-
there is a dhcp but it isn’t configured for this demand.
According to different situations, several information has to be provided for the CD boot image by interactive input. The most simple case is to provide no further information. Eventually the clients hostname can be passed by hn=<hostname>. Using the option ASK_CONF=1 several parameters can be queried. Pressing F1 at the CD prompt shows the syntax.
Please read the chapter Create a new client using the opsi-client-bootcd at the opsi-getting-started manual.
The linux bootimage prepares for reinstallation
The bootimage again performs a dhcp request and configures the network interface according to the perceived information. Afterwards the configuration data for the client will be loaded via opsi web service.
It also holds the information on how to partition the hard disk, what file system to use and which operating system to install. Also it provides the encrypted password to connect the file share.
These information will be combined with some information taken from the dhcp response and then be passed to the installation script for further processing.
Then the password for the user pcpatch will be decrypted with the transferred key to mount the installation share and then call the installation script from the mounted share to start the installation of the operating system. What specific operations the script performs depends on the operating system which is to be installed. Below the steps of a Windows 10 installation will be described.
Prepare the disc: On the hard disk the bootimage creates a new partition (size of 4 GB), formats it and installs a bootable ntloader kernel.
Copy the installation file: The files required for OS installation and the setup files for the opsi-client-agent (which is the opsi software distribution pack) will be copied from the server file share (e.g. /var/lib/opsi/depot/win10/installfiles) to the local hard disk.
Maintain the configuration informations: Some of the configuration and control files contain replacement characters, which will be patched before starting the actual installation. With a specified script (patcha-script) the placeholders will be replaced with parameters taken from the information packet. This is built from configuration files and the dhcp-response. For example the file unattend.xml, which is the control file for unattended OS Installation, will be patched with specific information like host IP, client IP, client name, workgroup, default gateway etc..
Prepare Reboot: Bootrecords will be installed which will start the Windows setup program at the next reboot. The patched unattend.xml is passed to the setup as the control file for unattended installation.
Reboot: During the previous boot, the named pipe (which is indicating a request for installation) has been removed by reading it once. So the next PXE boot will load the default netboot response, which executes the command localboot 0. The local boot loader will be started and the setup for operating system installation starts.
These steps are controlled by an OS specific python script.
Installation of OS and opsi-client-agent
The OS installation bases on the Microsoft unattended setup. Part of this is the standard hardware detection. In addition to the possibilities given during an installation from non-OEM or slipstreamed installation media, drivers and patches (i.e. service packs) can be installed during the initial installation, making the separate installation of drivers obsolete.
One feature of the unattended installation is the possibility to initiate additional installations after the main installation is finished. This mechanism is used to install the opsi-client-agent, which implements the automatized software distribution system. An entry in the registry marks the machine as being still in the reinstallation-mode.
The final reboot leads to starting the opsi-client-agent service for software distribution prior to the first user login. Based on the value of the aforementioned registry key the opsi-client-agent switches into reinstallation-mode. Therefore, regarding the configuration status of each software packet, each packet which is marked as action status ”setup” or installation status ”installed” within the configuration of that client will be installed. After all the designated client software has been installed, the reinstallation process is finished and the internal status is switched back from reinstallation-mode to standard-mode. In standard-mode only software packages that are marked as action status ”setup” will be installed.
How the patcha program works
As mentioned above the information collected from dhcp and opsi-webservice will be used to patch some configuration files as e.g. unattend.xml. The program used for patching is the script /user/local/bin/patcha.
This script replaces patterns like @flagname() in a file with values taken as flagname=value from the specified properties in the Windows 10 product. In the files that have to be patched, the search and replace pattern must start with @, might have an optional after the flagname and must have one or more trailing .
So by calling patcha -f <patchValues> <filename> the file <filename> will be patched with information from the set product properties, stored in the file <patchValues>. The file <patchValues> is generated before the installation from the product properties.
Usage: patcha [-h|-v] [-f <params file>] <patch file>
Fill placeholders in file <patch file>
Options:
-v Show version information and exit
-h Show this help
-f <params file> File containig key value pairs
If option not given key value pairs from kernel cmdline are usedpatcha patches one tag per line
Caveat: patch a patches only the first pattern of each line.
Each pattern will be expanded (or reduced) to the length of the value to be replaced with and then replaced. Trailing chars will not be affected.
Examples:
With the input file try.in
cat try.in
tag1=hallohallohallo1 tag2=t2and the file patch.me to be patched:
cat patch.me
<#@tag1##########################>
<#@tag2##########################>

8.2.3. Some hints to the NT6 netboot products (Win7 to Win 10)
All netboot products with the version >= 4.1.0.0 require an opsi-winst >= 4.12.0.13 installed on the opsi server.
The netboot products with the version 4.1.0.0 also run on opsi 4.0.7.
Windows OS installations on systems with more than one hard disk are now supported with the new multidiskmode property.
The multidiskmode property allows to select the target disk for the Windows installation by selecting the disk number. It is also possible to select the first SSD by using prefer_ssd or to select the first rotational (classic) disk by prefer_rotational
In order to work with the multidisk mode, the property winpenetworkmode has to be true.
|
By using the multidiskmode on a computer with MBR BIOS you have to make sure, that the by multidiskmode selected disk is also the first disk in the BIOS boot sequence. On UEFI BIOS systems no further actions are necessary, due to the fact that the boot sequence it’s controlled by the installation software. |
The preparation of a Windows installation starts with the opsi-linux bootimage, which select and prepares the hard disk. It also copies a Windows PE to a partition of the hard disk. This Windows PE is booted in order to start the Windows setup.
Starting with the 4.1.0.0 netboot products we use an opsi-script inside the Windows PE. This has the following advantages:
-
Easier and clearer scripts
-
The creation of a log file of the actions inside the PE
-
Sending of this log file to the opsi server
The netboot products for the installation of the operating systems of the NT6 familiy, contain several properties which will be described below.
- additional_drivers
-

-
This property is used to select the target disk of the Windows installation.
Possible values are: "0","1","2","3","prefer_ssd","prefer_rotational"
The values "0","1","2","3" are the index of the hard disks ("0"= 1. harddisk)
The value "prefer_ssd" selects the first SSD.
The value "prefer_rotational" selects the first rotational (classic) disk.
This property is ignored on systems with only one disk.
Default = "0" - orgname

8.2.4. memtest
The product memtest is a utility to perform a memory test on a client.
8.2.5. hwinvent
This product does a hardware inventory of the client.
8.2.6. wipedisk
The product wipedisk overwrites the complete hard disk (partion=0) or several partitions with different patterns. The number of consecutive write operations to perform is specified as the {product-property iterations (1-25).
8.3. Inventory
The localboot products hwaudit and swaudit and the netboot product hwinvent are available for inventory purposes.
8.3.1. Hardware Inventory
The hardware inventory is controlled in opsi via a configuration file. This means that the information how and which data is collected is not hardwired into the corresponding products hwaudit and hwinvent. Rather, these products are controlled via a configuration file. For this purpose, each time an inventory product is executed, the configuration file is read in and interpreted via the opsi web service. At the same time, this configuration file also controls the structure of the database, so that an extension of this configuration file also entails an extension of the database schema.
The configuration file is /etc/opsi/hwaudit/opsihwaudit.conf.
In this file all objects to be inventoried are defined and is described how the data belonging to this object is to be collected (under Linux and under Windows). At the same time, the associated data structure is also defined.
For simplification, this configuration file contains inheritance mechanisms that are based on an object orientation. The background to this is the fact that many objects have identical data fields, e.g. Name and Vendor. This general information is defined in virtual hardware classes. The actual inventory objects are then structural hardware classes, which can inherit many properties from the above virtual classes.
An example to explain this mechanism:
The configuration file first defines a virtual class named "BASIC_INFO". This defines the properties (Values):
-
"name"
-
"description"
Next comes the virtual class named "HARDWARE_DEVICE", which inherits all the properties of "BASIC_INFO" and defines the following additional ones:
-
"vendor"
-
"model"
-
"serialNumber"
Next comes the first object, which we also find in the inventory, the first structural class name "COMPUTER_SYSTEM", which inherits all properties of "HARDWARE_DEVICE" and defines or overwrites the following additional ones:
-
"name"
-
"systemType"
-
"totalPhysicalMemory"
Various properties are described in the context of the definition of a class and its values:
-
Class definition:
-
"Type"
is "STRUCTURAL" or "VIRTUAL" -
"Super"
specifies the class from which to inherit. -
"Opsi"
specifies the name of the class, which will later be used as the display name in opsi.
-
Furthermore, the class definition can indicate how this data is collected. This information can also be used to define the values.
-
For inventory under Linux:
-
"Linux": "[<command>]<parameter>"
Execution of the command line program <command>, with the argument <parameter>. Currently the supported programs are lshw, dmidecode, lsusb and lspci. -
"Python": "<python code with place holder>"
Execution of the specified Python code whereby the placeholder is then replaced by the determined values.
-
-
For the Inventory under Windows:
-
"WMI": "<wmi select statement>"
WMI query to be executed. Apart from the default (root\cimv2), custom namespaces can be used (e.g.namespace=root\\cimv2\\security\\microsofttpm:SELECT * FROM Win32_Tpm). -
"Cmd": "<Python text object with place holder>"
In this case, this is the relative path to an executable Python program, whose output replaces the placeholder. -
"Registry": "[<registry key>] <value name>"
The value of <value name> is read from the registry in <registry key>.
The registry is read in an architecture-specific manner. This means that the 64-bit branch of the registry is read on a 64-bit system.
-
-
Value Definition:
-
"Type": "<MySQL database type>"
<MySQL database type> specifies the data type which will be used to create this value in the database. -
"Scope": "<scope>"
The <scope> field is used in the following way:
"g" means: This attribute is the same for all devices of this type.
"i" means: This attribute can have different values for devices of this type. -
"Opsi": "<id>"
<id> is the opsi internal name of the field. This can be localized for output via the files in/etc/opsi/hwaudit/locales. -
"WMI": "<id or command>"
<id or command> is either the name of the WMI command, specified in the class definition, which outputs the value, or a seperate WMI command. -
"Linux": "<id>"
<id> is the name of the Linux command, specified in the class definition, which outputs the value. -
"Condition": "<condition>"
<condition> is a condition which must be fulfilled, in order for the value to be determined. For example, if the <condition> is defined as "vendor=[dD]ell*", then the values of "vendor" must contain either Dell or dell.
-
Here is an example of the class "COMPUTER_SYSTEM":
{
"Class": {
"Type": "STRUCTURAL",
"Super": [ "HARDWARE_DEVICE" ],
"Opsi": "COMPUTER_SYSTEM",
"WMI": "select * from Win32_ComputerSystem",
"Linux": "[lshw]system"
},
"Values": [
{
"Type": "varchar(100)",
"Scope": "i",
"Opsi": "name",
"WMI": "Name",
"Linux": "id"
},
{
"Type": "varchar(50)",
"Scope": "i",
"Opsi": "systemType",
"WMI": "SystemType",
"Linux": "configuration/chassis"
},
{
"Type": "bigint",
"Scope": "i",
"Opsi": "totalPhysicalMemory",
"WMI": "TotalPhysicalMemory",
"Linux": "core/memory/size",
"Unit": "Byte"
},
{
"Type": "varchar(50)",
"Scope": "i",
"Opsi": "dellexpresscode",
"Condition": "vendor=[dD]ell*",
"Cmd": "#dellexpresscode\dellexpresscode.exe#.split('=')[1]",
"Python": "str(int(#{'COMPUTER_SYSTEM':'serialNumber','CHASSIS':'serialNumber'}#,36))"
}
]
},The last value, "dellexpresscode", is particularly interesting:
This only makes sense if it is also a Dell computer, hence the condition.
Under Windows the command line program dellexpresscode.exe is executed, which is located as seen from hwaudit.exe in the subdirectory dellexpresscode\. This produces an output in the form: dellexpresscode=123456789. With the .split('=')[1] after the placeholder, the value after the equal sign is used.
Under Linux it is checked in which element (COMPUTER_SYSTEM or CHASSIS) a value was found for serialNumber and this is then used to calculate the Dell expresscode.
The opsi names of the values are translated using the files found in /etc/opsi/hwaudit/locales/*.
Example of /etc/opsi/hwaudit/locales/en_US:
COMPUTER_SYSTEM = Computer COMPUTER_SYSTEM.systemType = Type
The class name COMPUTER_SYSTEM is translated into "Computer". The opsi attribute "systemType" of the class COMPUTER_SYSTEM is translated into "type". Finally this note: If a new field is created, you should create it in the locale files, even if you do not translate the term yourself. This prevents "Warning" messages from being generated while running.
After you have modified the configuration file and the locales, you have to execute the following command so that the changes are also transferred to the database:
opsi-setup --init-current-configFurthermore you have to completely reload the data in opsi-configed: File / Reload all data.
The source code of this package can be found on GitHub: opsi-org/hwaudit
8.3.2. Software Inventory
Software inventory is done with the localboot product swaudit. The information from the uninstall path of the registry is collected and supplemented with additional information about hotfixes and license keys.
The source code of this package can be found on Github: opsi-org/swaudit
8.4. opsi subscriptions
8.4.1. Initial Deployment of opsi subscriptions
To provide the required packages, you can download them manually or install all packages after editing the configuration of the opsi-package-updater.
8.4.2. Configuration of the opsi-package-updater / updating the opsi subscriptions
For further operation it is recommended to save the repository configuration in /etc/opsi/package-updater.repos.d/. You will receive a corresponding configuration file with your access data.
| If using a proxy, the access must be configured in these files! |
It then offers to ony install the required packages from the new repositories:
# Example: Install packages for mshotfix, OS Windows 7 x64 / Server 2008 R2 and Windows 10 / 2016 / 2019 x64
opsi-package-updater --repo uib_abo_mshotfix install mshotfix mshotfix-win7-win2008r2-x64-glb mshotfix-win10-win2016-x64-glb
# Example: Install packages for Office 2016
opsi-package-updater --repo uib_abo_msoffice install office_2016_hotfix
# Example: Install packages for the standard opsi products: firefox and libreoffice
opsi-package-updater --repo uib_abo_standard install firefox libreofficeIt is possible to install only required packages, e.g. only the packages to update Windows 7:
opsi-package-updater -v install mshotfix mshotfix-win7-x86-glb mshotfix-win7-win2008r2-x64-glbTo update the packages the usage of opsi-package-updater is recommended.
By executing opsi-package-updater -v update you can update the installed packages, for example via a cronjob.
An equivalent is to update the packages for each repository:
# Updating packages for mshotfix
opsi-package-updater --repo uib_abo_mshotfix update
# Updating packages for msoffice
opsi-package-updater --repo uib_abo_msoffice update
# Updating packages for standard products
opsi-package-updater --repo uib_abo_standard update8.4.3. Configuration of default properties
When installing opsi packages non-interactively, the default properties of the packages are saved as default on a opsi-config-server or opsi-server.
As of opsi version 4.0.5, the default properties of the opsi-server can be set via the management interface opsi-configed.
If you subsequently install a newer package version using opsi-package-manager or opsi-package-updater, the default properties of the depot will be retained.
8.4.4. Subscription MS-Hotfixes
Regular updates for the product MS-Hotfix (OS hotfixes for Windows 7 / 2008 R2, Windows 8.1 / 2012 R2, Windows 10 /2016).
| Versions no longer supported by Microsoft are displayed as "failed": 1507 "non"-LTSB, 1511 and 1607 "non"-LTSB except Education and Enterprise versions. |
The updates will be available within three working days after the release of a patch that Microsoft considers to be important or critical.
| Rating | Description |
|---|---|
Critical |
A vulnerability whose exploitation could allow code execution without user interaction. These scenarios include self-propagating malware (e.g. network worms), or unavoidable common use scenarios where code execution occurs without warnings or prompts. This could mean browsing to a web page or opening email. Microsoft recommends that customers apply Critical updates immediately. |
Important |
A vulnerability whose exploitation could result in compromise of the confidentiality, integrity, or availability of user data, or of the integrity or availability of processing resources. These scenarios include common use scenarios where client is compromised with warnings or prompts regardless of the prompt’s provenance, quality, or usability. Sequences of user actions that do not generate prompts or warnings are also covered. Microsoft recommends that customers apply Important updates at the earliest opportunity. |
Moderate |
Impact of the vulnerability is mitigated to a significant degree by factors such as authentication requirements or applicability only to non-default configurations. Microsoft recommends that customers consider applying the security update. |
Low |
Impact of the vulnerability is comprehensively mitigated by the characteristics of the affected component. Microsoft recommends that customers evaluate whether to apply the security update to the affected systems. |
The opsi-mshotfix package uses (like WSUS Offline Update http://forums.wsusoffline.net/viewtopic.php?f=7&t=172 coverage of WSUS Offline Update) to download Microsoft’s update catalog file wsusscn2.cab, to identify the required patches. This catalog file contains at least all the "critical" and "security-relevant" updates, but not necessarily all the "important" and "optional" updates.
The opsi mshotfix packages have a modular structure. The basic package "mshotfix" contains only a script for installing the patches. The actual patches are contained in separate packages.

Installation:
opsi-package-manager -i mshotfix_201008-1.opsiTo set to setup wherever the product is installed:
opsi-package-manager -iS mshotfix_201008-1.opsiIn addition to the basic package, the patch packages are installed in the same way. However, since these packages do not contain any installation scripts, they can only be used together with the basic package, i.e. you cannot set them separately on setup. The mshotfix basic package is responsible for the client installation.
Since package mshotfix 201304-1, a list of patches installed by mshotfix is stored locally in the file C:\opsi.org\mshotfix\deployed.txt.

#####################################
Chapter 4: Administration
You can create and place files on the end user’s machine to manage
features related to security, privacy, use of disk
space, etc.
Privacy and security settings (mms.cfg)
As a network administrator, you can install Flash Player across the
environment while enforcing some common global
security and privacy settings (supported with installation-time
configuration choices). To do this, you need install a file
named mms.cfg on each client machine.
The mms.cfg file is a text file. When Flash Player starts, it reads its
settings from this file, and uses them to manage
functionality as described in the following sections.
mms.cfg file location
Assuming a default Windows installation, Flash Player looks for the
mms.cfg file in the following system directories:
32-bit Windows - %WINDIR%\System32\Macromed\Flash
64-bit Windows - %WINDIR%\SysWow64\Macromed\Flash
Note: The %WINDIR% location represents the Windows system directory,
such as C:\WINDOWS.- assetcachesize

This package contains the msi installer from Google (see Chrome for Business FAQ https://support.google.com/chrome/a/answer/188447?hl=en )
remarks:
The uninstallation and installation of google-chrome.msi sometimes fails.
Therefore there are different approaches in the opsi package to increase the reliability of the installation.
One customer reported a success rate of 100% for 40 installations with the following property settings:
-
install_architecture: 32 -
reboot_on_retry: True -
reboot_after_uninstall: True -
timeout: 240
In our internal tests we use:

Mozilla Firefox : firefox
firefox 60.6.1esror66.0.3-1
The firefox-package contains Mozilla Firefox in German, Englisch, French and Dutch.
All by Mozilla supported versions are provided.
Firefox can be configured centrally
a) either via a central configuration file mozilla.cfg (see http://kb.mozillazine.org/Locking_preferences)
b) or via a policies.json (see https://github.com/mozilla/policy-templates/blob/master/README.md)
which must be placed in the following directory:
/var/lib/opsi/depot/firefox/custom/When the package is installed again using opsi-package-manager -i <firefox-paket>, the configuration files found are retained via the preinst/postinst-mechanism and can then be selected using the "mozillacfg" property.
-
example:
cat /var/lib/opsi/depot/firefox/custom/mozilla.cfg // lockPref("browser.startup.homepage", "http://www.uib.de"); lockPref("network.proxy.type", 1); lockPref("network.proxy.http", "router.uib.local"); lockPref("network.proxy.http_port", 3128);
As an alternative to a mozilla.cfg, you can also integrate an autoconfig.zip created with the CCK2 using the property "mozillacfg".
opsi WAN/VPN extension: The package must be reinstalled with opsi-package-manager after changes in the custom directory, so that the file <productid>.files is updated.

9. opsi Extensions
9.1. Activation of non-free modules
Even if opsi is open source, there are some additional components that were created or maintained as part of a co-funding project and are not (yet) free of charge.
At the moment (December 2016) these are:
-
MySQL backend for configuration data (see mysql backend for configuration data)
-
UEFI support (see opsi with UEFI)
-
opsi license management module (see opsi License Management)
-
Support for clients over WAN/VPN (see opsi WAN/VPN extension)
-
opsi WIM Capture (see opsi WIM Capture)
-
opsi local image (see opsi local image) and opsi-vhd-reset (see opsi vhd reset)
-
opsi Linux agent (see opsi Linux Support)
-
opsi Nagios connector (see opsi Nagios Connector)
-
User roles (see Management of user rights and roles)
-
the Scalability1 extension to increase performance in very large installations
You can find more information on this topic at opsi cofunding projects.
As long as the additional extensions are in the cofunding state, they can only be used freely for evaluation purposes, but for permanent and normal use the cofunding contributions must be paid.
Which modules are allowed is specified on the opsi server in the activation file /etc/opsi/modules.
It is a simple text file with information about which module is activated (for what number of clients).
This file is protected against changes with a digital signature. If no information is given, the default values are used.
If the activation file does not exist, only the default free components from opsi are available.
In the case of temporary activation, the expiration date is included in the file.
In order to receive a temporary activation file for evaluation purposes, please contact info@uib.de. As part of participation in the corresponding cofunding projects, you will receive an activation file for the permanent and normal use of the activated components.
When you have received a modules-file, copy it to /etc/opsi.
Then run the following command to set the correct access rights:
opsi-setup --set-rights /etc/opsiThen restart opsiconfd.
Check the activation using one of the following methods:
In opsi-configed you can display the status of your activation via the menu item Help / opsi modules.
Using the method backend_info you can check with opsi-admin which modules are activated.
| Do not publicly share the file or the output of this command, at least not without deleting the signature. |
$ opsi-admin -d method backend_info
{
"opsiVersion" : "4.0.1",
"modules": {
"customer" : "uib GmbH",
"vista" : true,
"vpn" : true,
"license_management" : true,
"expires" : "never",
"valid" : true,
"multiplex" : true,
"signature" : "THIS-IS-NO-VALID-SIGNATURE",
"treeview" : true,
"mysql_backend" : true
}
}9.2. User roles (via opsi-configed)
The feature user roles must be activated in the modules file. The functioning is explained in Section 4.16.1, “Management of user rights and roles”
9.3. opsi directory connector
9.3.1. Introduction
The opsi directory connector is a tool to transfer data from a directory service to an opsi installation. This avoids the need of maintaining data in different systems.
9.3.2. Prerequisites
This module is currently a co-funded opsi extension.
There are a number of prerequisites for using this module. This means that you need an activation file. You will receive this activation when you buy the extension. For evaluation purposes, we also provide you with a temporary activation free of charge (mail to info@uib.de).
General Requirements
The source directory service must implement the LDAP protocol.
The target opsi server should run at least opsi 4.0.7. Older versions may work, but have not been tested.
The machine running the connector must have access to the directory and opsi server via the network. It is possible to run all components on the same machine, but it is assumed that separate machines are used for each component.
Hardware Requirements
These requirements are intended for basic use in a small environment with up to 500 clients. These requirements may be greater in large environments, which is why adjustments may be necessary.
-
256 MB of free memory
-
Network connections
Software Requirements
The installation and operation is only supported on Linux. Support for Windows is not planned.
By using standardized protocols for communication, no additional opsi- or directory service-specific components are required.
9.3.3. Installation
To install the connector please add the opsi repository as described in the Getting Started document.
Then use the package manager of the operating system to install the package opsi-directory-connector.
On a Debian-based machine the installation can be done as follows:
apt-get install opsi-directory-connector9.3.4. Configuration
The connector uses a number of configuration options and can be adapted to a wide variety of environments.
The configuration is done via a configuration file in JSON format, which must contain valid JSON.
To specify Boolean values, please use true or false.
Text has to be entered with double quotation marks, for example "this is text".
An example configuration is provided as /user/share/opsi-directoy-connector/opsi-directory-connector.example.conf.conf
This file can be used as a template for your own configuration.
cp `/user/share/opsi-directoy-connector/opsi-directory-connector.example.conf.conf /etc/opsi/opsi-directory-connector-custom.confDirectory settings
These settings are required to establish a connection to the directory service and to limit the search scope to specific areas and objects.
{
"directory": {
"address": "ldap://192.168.12.34",
"user": "DOMAIN\\opsiconnector",
"password": "insertpasswordhere",
"passwordFile": "",
"search_base": "dc=testcompany,dc=local",
"search_query_computers": "(objectClass=computer)",
"identifying_attribute": "dn",
"connection_options": {
"paged_search_limit": 768
}
},
…
}Under address you have to specify at which address the server can be contacted.
If the protocol ldaps or the port 636 is used a SSl connection to the directory is opened. Example:
"address": "192.168.12.34:636",User and password are used for authentication to the directory.
If a value is given for passwordFile, this is interpreted as the path to a file that contains the password.
The content of this file will be used as the password.
This means that the password does not have to be stored in plain text in the configuration file.
This will override the value set for password, if the file can be read.
| We recommend using a dedicated user account. |
|
Depending on the directory software used and its configuration, the format for the username can be different. Besides Down-Level Logon Name in the style of DOMAIN\\username, the format can also be User Principal Name in the style of user@domain, or a Distinguished Name (DN) like uid=opsiconnect,cn=users,dc=test,dc=intranet.
|
With search_base you specify from which point the connector looks for matching entries.
The filter used to search for clients can be configured via search_query_computers.
Through the optional parameter identifying_attribute it is possible to set which attribute should be used for the unique identification of a client. This is possible since version 23.
The standard used here is dn.
A common alternative to dn is the value distinguishedName, this variant is often used in Microsoft Active Directory.
The connection_options parameter contains additional options for configuring the connection.
The verify parameter determines whether or not the certificate should be verified for an SSL connection. In addition, the path to a CA file can be specified. If a file is specified, verification is performed via this file.
With start_tls it can be controlled whether a secured connection is started after logging in to the directory.
If the optional parameter paged_search_limit is present and if its value is an integer, multiple queries are used to read the elements from the directory. The maximum number of elements an answer contains is controlled by this value.
This behavior has been supported since version 20.
| Additional connection options will be implemented on request. |
Since version 14 it is possible to test the connection to the directory via the parameter --check-directory, without establishing a connection to the opsi server.
Connection to Univention Corporate Server
A complete Distinguished Name must be used as the user name for a connection to Univention Corporate Server (UCS).
This has the form uid=<username>,cn=users,dc=company,dc=mydomain.
On UCS, LDAP can be reached via ports 7389 (unsecured) or 7636 (SSL-secured).
If Samba is also installed on the server and set up as an AD-compatible domain controller, it listens on ports 389 (unsecured) or 636 (SSL-secured).
To use the SSL-secured ports, the connection option start_tls must be set to true.
These two possible connections also differ in the type of login name. With LDAP, uid=… is used, whereas with Samba, dn=… is used.
Generally, you will search for computer objects in the computers container.
The following command outputs the appropriate value for search_base:
echo "cn=computers,$(ucr get ldap/base)"To search for Windows clients you can set search_query_computers to (objectClass=univentionWindows).
How to create a user with read-only access can be found in the Univention Wiki: Cool Solution - LDAP search user
Behaviour settings
These settings control the behaviour of the connector.
{
…
"behaviour": {
"write_changes_to_opsi": true,
"root_dir_in_opsi": "clientdirectory",
"update_existing_clients": true,
"prefer_location_from_directory": true,
"group_handling": "dn",
"group_description": "dn",
"override_root_dir": true
},
…
}If write_changes_to_opsi is set to false, no data will be written to opsi.
This setting can be used to check the settings before they are applied.
root_dir_in_opsi specifies which group should be used as the root group in opsi.
You have to ensure that this group exists.
The group clientdirectory is shown in configed as DIRECTORY.
So if clients or groups should appear directly in DIRECTORY, the value clientdirectory must be entered as the value for root_dir_in_opsi.
|
If update_existing_clients is set to false, clients already existing in opsi will not be changed.
If this is set to true, any manually entered data will be overwritten with the values from the directory.
If prefer_location_from_directory is set to true, clients in opsi are moved to the position they have in the directory.
To deactivate this behavior, this value must be set to false.
Since version 31, group handling can be controlled via the optional key group_handling.
The default is cn. Groups are derived from the DN of a computer and created accordingly as part of the opsi directory. A client can only be member of one group.
If the group handling is set to ucsatschool, the behavior is adapted for use in UCS@School environments.
The opsi-directory-connector will automatically search for schools and find their rooms, which are then synchronized to opsi.
For every school a group will be created in opsi.
In UCS@School a computer can be a member of multiple rooms. To follow this behaviour, the groups are not created as a group within the opsi directory, but as a normal group, so that a client can also be found in multiple groups.
If the groups in OPSI should be created under DIRECTORY after all, the switch override_root_dir can be set to false. override_root_dir is only available for group_handling ucsatschool and the default value is true.
If override_root_dir is set to false and the groups are thus stored in OPSI under DIRECTORY, it should be ensured that each school computer has only been assigned to one room.
With group_description the description of the OPSI groups can be customized. The following values are possible:
-
dn: The dn of the group is stored in OPSI as the group description. -
directory: The group description is read from thedescriptionfield of the directory group. -
If the value is not set or is set differently, the description is filled with the name of the group.
...
"behaviour": {
"group_handling": "ucsatschool",
...
"group_not_in_directory": true,
"opsi_clients_to_ignore": {
"clients": ["win1.uib.local","win2.uib.local","win3.uib.local"],
"groups": ["server"]
}
}
...If group_not_in_directory is set to true, all clients that are not in the directory are added to the not_in_directory group. This option is only available with group_handling uscatschool. With the opsi_clients_to_ignore parameter clients or whole groups can be excluded from this rule.
Mappings
With a system as flexible as a directory service, the connector needs information about which attributes in the directory should be matched to which attributes in opsi.
{
…
"mapping": {
"client": {
"id": "name",
"description": "description",
"notes": "",
"hardwareAddress": "",
"ipAddress": "",
"inventoryNumber": "",
"oneTimePassword": ""
}
},
…
}There is a mapping for client attributes. The key of the mapping is the attribute in opsi and the value is the attribute from the directory service. If the value (in the mapping) is empty, no mapping will be done.
| If the value read from the directory for the ID of the client is not recognizable as a FQDN, a corresponding FQDN will be created. The domain part for this is formed from the DC values of the element. |
On Univention Corporate Server (UCS), the value for hardwareAddress can be set to macAddress if the connection is established via LDAP (port 7389 or 7636).
|
In the "mapping" area, the assignment of clients to depots can be defined. Currently there is only the mapping type "network".. With the "network" type, a client is assigned to a depot if the ip address of the client matches the network address range ("networkAddress") of the depot. Alternatively, a list of network ranges can be assigned to a depot.
{
...
"mapping": {
...
"depot": {
"type": "network",
"test-depot1.test.local": ["192.168.24.0/24","192.168.25.0/24"],
"test-depot1.test.local": ["192.168.27.0/24","192.168.28.0/24"]
}
},
...
}Manual assignment of group names
Group names can usually abe used without any major adjustments. However, it can happen that group names exist which are invalid in opsi.
For these special cases, a manual assignment of group names can be made, which allows these cases to be handled.
To configure this, an entry group_name is created in mapping, which holds the mapping from the directory service to opsi.
The name is not changed for groups that do not appear in this assignment.
Group names are always processed in lower case letters, which is why the entries here must be made in lower case letters.
This is possible since version 23.
The following example maps the group _server originating from the directory service to the group server in opsi.
{
...
"mapping": {
"client": {
...
},
"group_name": {
"_server": "server"
}
},
...
}| Please be careful with this feature as it may introduce undesirable side effects. Therefore, this option should only be used for special cases. |
opsi connection settings
This controls how the connector connects to opsi.
{
…
"opsi": {
"address": "https://localhost:4447",
"username": "syncuser",
"password": "secret",
"exit_on_error": false,
"passwordFile": "",
"connection_options": {
"verify_certificate": true
}
}
}Enter the address of the opsi server under address.
Do not forget to specify the port!
| A proxy for the connection can be set via the environment variable HTTPS_PROXY. |
User and password are used for authentication to the opsi server.
If a value is given for passwordFile, this is interpreted as the path to a file that contains the password.
The content of this file will be used as the password.
This means that the password does not have to be stored in plain text in the configuration file.
This will override the value set for password, if the file can be read.
| We recommend using a dedicated user account. The creation of additional users is described in the Getting Started manual. |
If the parameter exit_on_error is set to true, then any problem when updating the data in opsi - this can also be triggered by submitting values that are invalid in opsi - results in a break.
If this is set to false, errors are logged, but the execution is not terminated.
Under connection_options options for the connection to the opsi server can be set.
The verification of the server certificate is controlled by means of verify_certificate.
This value should be set to false when using self-signed certificates.
Since version 14 it is possible to test the connection to the opsi server via the parameter --check-opsi, without establishing a connection to the directory service.
9.3.5. Running the connector
After the installation a binary called opsi-directory-connector will be present on the system.
It is required to pass an argument --config together with the path to the configuration file.
opsi-directory-connector --config /etc/opsi/opsi-directory-connector-custom.conf| The user running the binary does not require any access to opsi as this is all stored in the configuration file. |
Example: recurring runs with systemd
The connector currently does one synchronisation run when executed, but the chances are good that you want to have a constant synchronisation of data.
It’s easy to automate the execution of repetitive runs.
We will be using systemd for this. In contrast to cronjobs, systemd will prevent simultaneous runs from occurring, which is why systemd is a good choice.
The following example will set up the connector to run five minutes after the machine starts, and every hour thereafter.
The following two files must be stored under /etc/systemd/system/, the directory for user-defined units.
One file is the timer, which calls our job repeatedly and the other is for the job itself.
Please fill the file opsi-directory-connector.timer with the following content:
[Unit]
Description=Start the opsi-directory-connector in regular intervals
[Timer]
OnBootSec=5min
OnUnitActiveSec=1hour
[Install]
WantedBy=timers.targetAnd this is the content of opsi-directory-connector.service:
[Unit]
Description=Sync clients from AD to opsi.
Wants=network.target
[Service]
Type=oneshot
ExecStart=/usr/bin/opsidirectoryconnector --config /etc/opsi/opsidirectoryconnector-custom.confTo enable the timer and start it right away, the following commands can be used:
systemctl enable opsi-directory-connector.timer
systemctl start opsi-directory-connector.timerIf the timer does not get started, it will start to run the next time the machine is restarted.
Example: recurring runs as cronjob
It is easy to automate the execution of recurring runs through a crobjob.
Please note that simultaneous runs can take place, which is why it is best to choose a larger synchronization interval. To avoid this problem, it is recommended to use systemd instead of cron!
The cronjob file can usually be edited through crontab -e.
For a synchronisation that happens every hour the following can be used:
0 * * * * /usr/bin/opsidirectoryconnector --config /etc/opsi/opsidirectoryconnector-custom.confcommand line arguments
Usage: __main__.py [-h] [--version] [--log-level {0,1,2,3,4,5,6,7,8,9}]

Check if a connection to the directory can be established and if items
will be received. (default: False)
--check-opsi
Check if a connection to the opsi server can be established. (default:
False)
--delete-clients DELETE_CLIENTS [DELETE_CLIENTS ...]
Delete list of clients from directory. (default: None)
--dry-run
Print what would be done. (default: False)
--config CONFIG
Path to the config. (default: None)Starting with version 39 the opsi-directory-connector uses the OPSI logger with loglevel 0-9. By default logs are written to /var/log/opsi-directory-connector and to stderr. With the parameters --log-level-stderr, --log-level-file the log level of the respective log can be set. --log-file defines the log file.
The log file is rotated after a specified size (default 5 MB) and by default one of these rotated log files is kept. The parameters --max-log-size and --keep-rotated-logs can be used to override the default values.
In addition to the command line parameters, the values can also be set in the configuration file or via environment variables. The following applies here:
-
Parameters overwrite everything
-
Environment variables overwrite configuration and default
-
Configuration overwrites default
Example configuration:
{
...
"log-level-stderr": 6,
"log-level-file": 3,
"keep-rotated-logs": 4
...
}If the directory connector is started with the --dry-run option, the individual steps are output without making any changes in OPSI.
With dry-run, in contrast to the configuration parameter write_changes_to_opsi: false, the output is adjusted,
to give a better overview of the actions. Example output:
---------- opsi actions ----------
Creating client client1.opsidc.intranet.
Creating client ds-win-client-2.opsidc.intranet.
Creating client ds-win-client-1.opsidc.intranet.
Creating client mac-client-1.opsidc.intranet.

----------------------------------
---------- summary ---------------
Create 6 clients and 0 groups.
0 clients removed from group.
Adding 4 clients to a new group.
----------------------------------9.3.6. Delete Clients from the directory
In the standard case the opsi-directory-connector has only read access to the directory. With the start parameter --delete-clients an independent run is started, which tries to delete the given objects from the directory.
For example:
opsi-directory-connector --config config.conf --delete-clients client1The objects can be specified more precisely:
opsi-directory-connector --config config.conf --delete-clients computers/test-clients/client1This call would fit on object cn=client1,ou=test-clients,ou=computers,dc=example,dc=org, but not
cn=client1,ou=clients,ou=computers,dc=example,dc=org. So the first object will be deleted.
Multiple clients can also be specified:
opsi-directory-connector --config config.conf --delete-clients computers/clients/client1 client2 client3
The delete-clients function should be used with caution.
|
The dry-run function can also be used with delete-clients.

9.4. opsi WIM Capture
9.4.1. Prerequisites for the opsi extension opsi wim capture
This module is currently a
co-funded opsi extension.
Some preconditions are required, in order to use this module. That means that you need a suitable modules file to unlock this extension. You can get this file by purchasing the extension module. For evaluation purposes you can get a temporary modules file without charge. ( → mail us at info@uib.de).
Technical requirements are opsi 4.0.6 with package versions:
| opsi-package | version |
|---|---|
opsi-linux-bootimage |
>= 20160111 |
opsi-client-agent |
>= 4.0.6.3-8 |
Windows Netboot >=7 |
>= 4.0.6.1-3 |
opsi-clonezilla |
|
win10-sysprep-app-update-blocker |
For the product opsi-wim-capture the share opsi_depot_rw must have read/write permission for the pcpatch. Check your Samba configuration.
|
-
Since opsi-wim-capture Version 4.1.x there is a full uefi support
-
install.esd (instead of install.wim) as target format is supported since opsi-wim-capture Version 4.1.x.
9.4.2. Quick Info
For the people who are looking for a quick guide, this is the place to start. More detailed information follows below.
Pre-requirements
-
Set boot priority of PXE-Boot / LAN-Boot on Computer BIOS to first priority
-
Computer must be configure with the following specifications on the properties of the Netboot-Products:
boot_partition_size=0
preserve_winpe_partion = true
windows_partition_label = WINDOWS
windows_partition_size=100%
setup_after_install=win10-sysprep-app-update-blocker -
Target product completion:
The target product used is usually one of the provided capture products, e.g.: win10-x64-capture
Winpe and Drivers directory can be created as symbolic links from the standard product.
The install files folder must be copied because the install.wim must be adapted.
In addition, Files from thecustomdirectory are copied or linked, e.g.: unattend.xml -
The property opsi-clonezilla imageshare = auto (is the default, deprecated //<servername>/opsi_images)
imagefile and runcommand will be replaced automatically opsi-wim-capture -
Install the latest Windows patches on the computer or install config-win10 and mshotfix.
-
All software, which should be integrated in the image, must be install on the computer.
-
Start of the product opsi-wim-capture:*
-
Completion from the following properties is required:
image_description = <Image description>
imagename = <image name>
target_product = win10-x64-captured -
Set opsi-wim-capture on setup
Install the computer with the new image:
-
Target product (e.g. win10-x64-captured) adjusting the following to setup:
Imagename= (Apply the same name from the property opsi-wim-capture)
9.4.3. Introduction
With NT6 (i.e. from Vista), Microsoft has introduced a new Image Format/ Container for OS Installation. Its called Windows Imaging Format (WIM). A WIM Image is not exactly an image of a disk or partition, but rather an archive of files and Metadata. A WIM file can contain several images. The default installation of an NT6 operating system works like this: setup.exe unzips an image from an install.wim file, configures it, and adds some additional drivers.
This way, an installation is quicker than with NT5. But then installation of Hotfixes with NT6 takes significantly longer, so that the basic install of Windows 7 will take 30 minutes, but adding all required Hotfixes may take several hours.
With this opsi extension, it is possible to read an installed Windows OS, including installed software, Hotfixes and configurations, and save it as a WIM image. This WIM file can then be used as a source for a fresh Windows Installation.
Our product opsi-wim-capture is made exactly for this purpose. Roughly, we boot off a PE partition, so that the PE can read the system partition and save it into a WIM file.
9.4.4. Overview of the Sequence
Capturing an installed Windows image works like this:
Preparation:
-
opsi - installation of a Windows OS with set property:
preserve_winpe_partition=true
boot_partition_size=0
windows_partition_size=100%
'setup_after_install=win10-sysprep-app-update-blocker
run the product opsi-wim-capture.
All the following steps will be controlled by the product opsi-wim-capture:
-
via opsi-clonezilla, makes a backup of the disk (OS and winpe partition)
-
backup of the opsi metadata
-
make winpe partition bootable, create winpe script (work.cmd)
-
sysprep of the installed systems (depersonalization)
-
boot winpe, capture of OS disk, write to destination product
-
restore of the original disk (OS and winpe partition) via opsi-clonezilla
9.4.5. Sequence Details
Preparation
Installation of a Windows OS must have the property set to true like this preserve_winpe_partition=true, because the winpe partition will be needed later.
After the Windows OS installation you can install additional Software and Hotfixes, configure the system manually or via opsi.
opsi-wim-capture
The whole sequence will need time, at least an hour. It will work unattended, though.
In case the property disabled is set to true (default=false), the process will be canceled immediately. This switch is for development only.
The setting of the property always_backup_before_sysprep will be checked. If yes, it’ll make a backup of the system via opsi-clonezilla.
|
In opsi-clonezilla, the runcommand is In order to avoid a never ending loop, we write a reboot flag, so that after writing the backup, we can see that this step has already been done. Technical note: We do not want to reboot again after restoring the backup, though (but the reboot flag is contained in the backup). Thats why the reboot flag is being set as a time stamp. In case the time stamp is older than 0.1 days (i.e. 2.4 hrs), it will be ignored. |
The system will reboot now, leaving the product opsi-wim-capture set to setup. opsi-clonezilla will start up and do the backup.
|
Why backup via opsi-clonezilla ? The sysprep action to follow will leave the OS partition unusable. An OS, that is set up from a captured WIM Image, will contain information about the sysprep run. Thus, it cannot be used for further capturing via opsi-wim-capture. Only perform repeat capturing using a previously restored opsi-clonezilla image. |
The product opsi-clonezilla is now being configured in a way that it will perform a restore on next run.
Now information about the installed opsi-products (and versions) will be stored on the client.
|
The productOnClient objects of all Localboot Products are being written to |
The machine’s opsi-client-agent is now being deactivated, so that it cannot run after deployment based on this image.
In order to be able to deploy the captured image like a default Windows Setup to any machine, it needs to be depersonalized. This will be done via sysprep.
| This does not mean all of the software will be depersonalized. It’s , that installed software holds data regarding on which computer it was originally installed. A config of that kind will be likely to cause problems, specially if you deploy the image to different machines. It might be a good idea not to capture all the software on the computer. |
If the property startcapture is set to false (default=true), will stop working after the sysprep, and shut down the machine. This makes sense only if you plan to take an image of the machine using a different tool.
In order to read the OS partition and writing it into the WIM file, we have to use a Windows OS, which cannot be the Windows OS we want to read (for obvious reasons). Therefore, we use the Windows PE we created and preserved at the initial installation. And afterwards:
-
Activation of the WinPE as bootable partition, creation of the required boot record, (if necessary) deactivation of drive letters of other partitions
-
Reading opsi metadata concerning installed products on the client, saving the data to a temporary folder on the client
-
some cleaning on the system we want to capture
-
Writing a command file, which will initiate the capturing at next WinPE boot.
-
Provisioning of further data for the WinPE run, like list of products from the property
start_after_capture -
Reboot the client
Now the WinPE starts and will do the actual capturing. Here are the details:
-
Mounting the opsi_depot_rw share, so that we can write to it.
-
Checking the architecture of the WinPE (32/64 Bit); start of the corresponding opsi-script interpreter.
-
Establishing a connection to the opsi-webservice
-
Re-activation of the drive letters
-
If the property
check_disk_before_capturecontains the value true (default=false), we performchkdskon the Windows OS partition. That will take time. -
Checking for existence of the target product stated in the property
target_producton our opsi_depot_rw share, and whether it contains aninstall.wimfile in the right place. -
Checking and creating a lock file within the
target_productfolder. If this file exists already, we cancel the process in order to prevent several capturing processes writing to the same WIM file. -
If the property
force_imagexis set to true (default=true), then we use theimagexcommand of our product opsi-wim-capture for capturing, even if the Windows PE has adismcommand. Otherwisedismwill be used, if available.Dismis faster, but might produce images that cannot be used for successful deployment. -
If the property
capture_modeis set toappend: Check, if there is an image of that name contained in theinstall.wim, and delete it.
The valuealways_createwill only be accepted, ifdismis being used. In this case, a newinstall.wimfile will be created. -
Start of the capture process. The previously mentioned tool (
imagexvsdism) and thecapture_modechosen will be used. The name of the image is set by the propertyimagename. The propertyimage_descriptionwill determine the description of the image.
This can take a long time to be completed.Keep in mind the name of the Image! The name of the image created can’t be automatically added to the list of installable images at the current time. You have to keep the name in mind and state the image name when deploying! -
Deleting of the lock file in the
target_productfolder. -
Merging the resulting log files.
-
Request action setup for products contained in the property
setup_after_capture.
At this time, also product dependencies will be resolved.
The property is a list and can contain several product IDs.
|
leave settings so that opsi-clonezilla will be set to setup! The machine will be depersonalized after the capture run, and thus remain unusable. Our product opsi-clonezilla is prepared, so that the backup taken earlier will be restored automatically. |
-
Deactivation of the WinPE partition, and re-activation of the OS partition (Windows).
-
Transfer of the logfile to the server. It will be appended to the existing logfile of the opsi-wim-capture run.
-
Reboot
If the product opsi-clonezilla has been set to setup, a restore of the disk is being performed automatically.
9.4.6. Products
Main Product opsi-wim-capture
The product opsi-wim-capture contains the following product properties:
-
always_backup_before_sysprep:
(true/false), Default=true,
Always make an opsi-clonezilla backup before sysprep. -
startcapture:
(true/false), Default=true,
Sets the productopsi-local-image-captureto setup, and reboots the machine -
disabled:
(true/false), Default=false,
If set to true, nothing will happen. Its only there for debugging. -
target_product:
Name of the target product: (Default = '')
This property is not intelligent, i.e. we do not check, if the image being copied matches the target product. You could easily write a win7-32Bit Image into a Win81-64Bit product without errors. But you shoud not do that! Furthermore, we recommend separated products for capturing, that are only target products in the capture process. (for instance win10-x64-captured).
|
The target product has to be prepared for deployment like any other Windows OS product. The target file within the target product will be the install.wim file (installfiles/sources/install.wim), which also contains the images provided by Microsoft. Our new OS image will either be created as a new install.wim , or be appended to the existing file. This is being controlled by the property :
-
capture_mode:
(append/always_create) Default=append:
append will append the newly created image to the existing install.wim .
If the install.wim contains an image that’s named like the new one, it will be deleted without warning. always_create will always create a new install.wim .always_create will not work with a WinPE based on Windows < 8 .
|
An Install.wim file is a container, that can contain several images. All of them have a name and a description, which can be controlled by the following properties:
-
imagename:
Default = '' -
image_description:
Default = '' -
The property
start_after_capture
this is a list of products that will be set to setup after completion of the capture process. Could be good to use for instance opsi-clonezilla, which will restore the backup taken before sysprep. -
force_imagex:
true/false (default=true) This will use theimagextool, even ifdismis available. -
opsi_depot_rw_host:
Normallyauto(default) or leave empty.
If notautoor empty: the host from which we mount the opsi_depot_rw share.
If the host is given, it must be a hostname, a FQDN or a IP Number
This property is only for situations where theopsi_depot_rwshare is not reachable at the opsi depot where the client is assigned to. -
checkdisk_before_capture:
Should we make a file system check on the system partition before we capture.
Default = false. -
verify_clonezilla_images:
Should Clonezilla check the imagesafter_save,before_restore,never,always
A verify check takes nearly the same time as the save or restore process.
Default =never
Target Products
The target products shall host the captured images.
Why target products ?
The target products do not differ from default opsi Windows netboot products. Technically, a standard win10-x64 they can be used as a target product.
We recommend the usage of dedicated target products, so that it is easy to differentiate a modified installation (opsi-wim-capture) from an unmodified installation (original Microsoft DVD).
Furthermore, it might be wise to keep a fall back product you can switch to in case the captured install.wim becomes unusable for some reason.
This decision is for you to make.
We provide the following target products:
-
win7-x64-captured -
win81-x64-captured -
win10-x64-captured
These products have to be equipped with required files from the OS DVDs like any other Windows netboot product (see our opsi-getting-started document).
Still, folders like winpe or drivers/drivers/additional/byAudit can be symbolic links to a directory in a suitable non-target product. Watch out: the Subfolder installfiles needs to be physically there (copy from Windows DVD).
9.4.7. Windows Installation via Target Product
(Deployment from a captured Image)
Restore of the opsi metadata from installed Products
The Problem:
If you reinstall a Windows with opsi, e.g. win10-x64, then during the installation of the opsi-client-agent all the local Boot products, which in this computer were previously marked as` installed`, will automatically be set to setup and thus reinstalled later.
This can not be completely carried out exactly in the rolling of a captured Image.
In the image is the backup from the opsi data that was stored during the capture process. This will be discovered when you install the opsi-client-agent and re-imported into the depot server. With it the products that were installed in the captured Image, now are on the newly installed computer mark as installed.
Should now all the products that are mark as installed set to` setup`, this would imply that all products installed already in the image will be re-installed. This is not desirable.
By the restoring from the opsi metadata of installed products there are two alternatives available now with opsi 4.0.7:
-
Alternative 1:
Restoring the metadata and retention of setup -Action Requests.
Products that are mark as installed will not be set to setup.
This is the default, and the behavior before opsi 4.0.7 -
Alternative 2:
Restoring the metadata. Products that are mark as installed will be set to setup except those which were contained in the restore metadata.
Alternative 1
By the deploy from a captured image, after the install, only the products which were already from the beginning of the OS-install set to setup will be automatically installed. These can be done through your intervention, or through the property setup_after_install.
Therefore only the products which stood at setup before installing the operating system will be installed in this case.
This is the default, and the behavior before opsi 4.0.7
Alternative 2
Variant 2 behaves similar to what would be the case of an installation without a captured Image:
* Restore of the metadata.
* Products that are mark as installed are then set to setup except those which were contained in the restore metadata.
This behavior is only available since opsi 4.0.7 and is not the default. Option 2 is made possible by enhancements to the opsi script and is part of the opsi-client-agent of 4.0.7.
In order to be able to apply this behavior a config must be set on (Host parameters) :
The Boolean configuration entry: clientconfig.capture.switch_installed_products_to_setup. If the entry for this client has the value true then variant 2 is applied, otherwise variant 1
host parameter can have specific client events activated or deactivated. The host parameter can be applied using the opsi-configed or the opsi-admin.
To create the host parameter over the opsi-admin the following commands are to be executed on the’opsi-config-server':
opsi-admin -d method config_createBool clientconfig.capture.switch_installed_products_to_setup "capture.switch_installed_products_to_setup" trueWith that you set for all computers Alternative 2.
To create the host parameter over the opsi-server select there Server Configuration / ClientConfig / And on the right side with the right mouse button: Add Boolean configuration entry.
9.4.8. Helper product opsi-wim-info
The product opsi-wim-info is useful to gather information about the images that are stored inside a install.wim. These information is written to the logfile.
Properties:
-
target_produkt
ProductId of the product where the install.wim file is searched.
9.4.9. Known Restrictions and Problems
The following restrictions are known as of today (13.7.2018):

9.5.2. Preconditions for using the opsi Linux Support
Technical precondition is opsi 4.0.5 with following packet versions:
| opsi packet | version |
|---|---|
opsi-linux-bootimage |
>= 20140805-1 |
The opsi support for Linux is based on a free Open Source component (the netboot products) and a co-funded component (the client-agent).
The opsi-linux-client-agent is a
co-funded opsi extension module.
In order to use the opsi Linux extension module, an activation file is required, this file can be acquired by buying the extension module. To obtain a temporary activation file for evaluation, please email us at info@uib.de.
For further details on handling extension modules please refer to the opsi manual.
9.5.3. opsi-linux-client-agent: 15 Free starts
The opsi-linux-client-agent includes 15 free starts by which the agent can be used without any activation
In detail: After the initial Install from the opsi-linux-client-agent the opsi-script can be started 15 times in service context without the need of activation.
This gives you the possibility to set a Linux computer with the corresponding opsi-products for the configuration needed.
For example, after the installation of the system you could use the product l-opsi-server to make of the newly installed computer an opsi-server.
For a long lasting maintenance of the installed Linux computers after the 15 free starts, it is recommended the activation of the feature, in order to continue taking advantage of its benefits.
9.5.4. Installation of the packages
The Linux-related packages can be loaded over the opsi-package-updater.
By default it already has the repository for the linux packages activated.
You can use the following command to install the packages:
opsi-package-updater -v --repo uib_linux install9.5.5. Introduction
A single management tool for Windows and Linux
The objective of the opsi Linux extension module is to provide an homogenous management system for heterogenous environments. The focus is on integrating both worlds into the same management processes and tools
This means, that a Linux installation is triggered the same way as a Windows installation. The Linux opsi-client-agent is based on the same source code as the Windows client and provides (when applicable) the same opsiscript instruction sets.
Independent from Linux distribution
The opsi Linux Support is designed to be independent from any special Linux distribution.
The following distributions are supported:
-
Debian
-
Ubuntu
-
Linux Mint
-
OpenSuse / SLES (Suse Linux Enterprise Server)
-
RHEL (RedHat Enterprise Linux)
-
CentOS
-
UCS
Please keep in mind that you need at least 4GB of RAM in the machine or VM if you want to install Linux Mint.
9.5.6. Linux netboot products v406 based on the distibution installer
With opsi v405 the installation of Linux targets has been controlled by the netboot product. The opsi v406 Linux netboot products are based on installer of the respective distribution.
This is a fundamental change of the structure and behavior of these products.
Overview of the changes:
-
Like with the unattended Windows installation, the Linux installer is equipped with an answer file to configure the unattended installation.
-
The installer of a distribution is not like with Windows an executable program, but is a combination of the distribution kernel and initrd implementation.
-
The system installation including partitioning, LVM, and all the basic software, are performed by the installers and not by the bootimage anymore.
-
For the Suse and RedHat like distributions, the installation sources have to be provided by you by introducing the DVD as an ISO-file on the depot share. This is comparable to the Windows installation, with the difference that the Windows installation files are stored in a different place and stored as the content of the DVD and not as an ISO file.
-
The installation of Linux Mint uses the content of the official installation media provided via an NFS share.
-
For the Debian like distributions, the installation sources are taken from the internet. Just the netboot versions of the distribution kernel with the associated initrd are placed on the depot share. These files are small, so they are included in the opsi package.
Since opsi 4.0.7 it is also possible to provide for some netboot products a local http repository. -
For further maintenance of the installation the opsi-linux-client-agent can be installed with the basic installation.
Description of the automated installation process:
-
The opsi-linux-bootimage boots, deletes the partition table and creates a small temporary partition.
-
The opsi-linux-bootimage fetches the initrd for the distribution and unpacks it on the temporary partition.
-
The opsi-linux-bootimage fetches the generic answer file, patches it (personalisation) and moves it to the initrd directory.
-
The opsi-linux-bootimage creates some helper scripts and configuration files (e.g. for installing the opsi-linux-client-agent) and moves them to the initrd directory.
-
The opsi-linux-bootimage packs the patched initrd directory
-
The opsi-linux-bootimage boots the distribution kernel with the patched initrd per kexec.
-
The distribution kernel with the patched initrd performs the unattended installation of the target system and finally installs the opsi-linux-client-agent.
Advantages:
-
The installation is done as specified by the distributor, which is of special importance for providing support in the business context.
-
The opsi integration of new releases is easier and faster available.
-
For Suse, RedHat and Linux Mint like distributions, the installation is done from the sources on the opsi-server, and therefore is faster and more stable than installing from the internet repositories.
Providing the installation media on the server
For Suse. RedHat and Linux Mint like distributions, the installation media is provided by an additional nfs-share: opsi_nfs_share.
To configure this share, there must be a NFS server installed and configured on the opsi-server:
Since opsi v4.0.6 stable this is done by the special package opsi-linux-support. This package is not installed by default and must be installed manually once, e.g.
apt install opsi-linux-supportIf a firewall is running on your system you need to configure it to accept TCP connections at port 80. Please consult the appropriate manual on how to do this.
The opsi-linux-support package performs the following tasks:
-
Installation of the applicable nfs-server package on the opsi-server. For Debian, Ubuntu, Suse this is the package: nfs-kernel-server. For Centos, Redhat it is the package nfs-utils.
-
The share
opsi_nfs_shareis created and exported:-
Create directory:
mkdir -p /var/lib/opsi/depot/opsi_nfs_share -
Add the share entry to /etc/exports:
/var/lib/opsi/depot/opsi_nfs_share *(ro,no_root_squash,insecure,async,subtree_check) -
Activate the export:
exportfs -r -
Check the successful export:
showmount -e localhost
The output should be:
Export list for localhost: + /var/lib/opsi/depot/opsi_nfs_share *
-
-
The share
opsi_nfs_sharehas the following directory structure:
opsi_nfs_share/<productId>/<arch>/<dvd>.iso
example:
opsi_nfs_share/opensuse15-2/64/openSUSE-15.2-DVD-x86_64.iso
The installation file must have an extension.iso, the name of the file does not matter. If there are several.isofiles in the same directory, it is not specified which one to use.
However the Linux Mint installation requires the installation media content, including hodden directories, to be copied into the specific `opsi_nfs_share subdirectory. -
Copy the installation DVD to the
opsi_nfs_shareand execute:
opsi-set-rights /var/lib/opsi/depot/opsi_nfs_share
IMPORTANT: use the standard installation DVDs of the distribution. Modified installation DVDs might have a different structure and therefore cannot be used in this context. -
If for any reasons the directory
/var/lib/opsi/depot/opsi_nfs_sharecannot be exported by the opsi-server per NFS (for instance because the depot share is already a NAS NFS share), so the NFS share to be used can be specified by a server config. Likeclientconfig.opsi_nfs_share=172.16.166.1:/var/lib/opsi/depot/opsi_nfs_share
|
Start order of involved services for SLES 12
It may occur that the Please make sure that after installing the NFS-server a reboot has been made. Then the services rpcbind and nfs-server need to be started in that exact order. The services can be restarted by the following commands: Then showmount works as expected: |

9.5.7. Linux v405 netboot products without distribution installer
Basic OS installation per netboot
To install Linux on a client, at the beginning the standard opsi-linux-bootimage boots per netboot. It is the same image as the one used for the Windows installation.
The bootimage automatically performs the partitioning and formatting of the hard disc (/ and swap). Next the installation of the basic Linux Operating System is performed (including network and ssh, but without X11). The installation process itself is quite different for the individual distributions, but has in common, that the installation is performed directly from the original distribution packages.
The opsi-client-agent for Linux can be installed, which enables the automated installation and configuration of further software packages.
The opsi-client-agent for Linux is available as a co-funded opsi extension module, the required opsi netboot products for Linux installation are available as free Open Source modules.
Because the base installation is done from the Standard opsi-linux-bootimage, there are some distribution dependent differences, that have to be installed and configured after the first reboot of the installed system. This is for example the SELinux installation of the RedHat like or the keyboard configuration of the Debian like systems. These after boot installations and patches are done by the standard localboot product l-os-postinst.
Common properties of the v405 Linux netboot products
The following properties for controlling the Linux installation are available with all netboot products:
-
askbeforeinst:
confirm start of the new installation on the client? (default=true) -
architecture:
architecture selection - affects the selection of the bootimage and the installation architecture. (default=64bit) -
system_partition_size:
size of the system partition - the size may be given as percent of the hard disk size or as absolute size (G=Gigabyte). If you choose another value than 100%, the remaining rest will be used as data_partition. (default=100%) -
swap_partition_size: +size of the swap partition. (default=2000M) -
data_partition_create:
create a data partition if there is some space left. (true/false) (default=true) -
data_partition_preserve:
preserve an existing data partition?
always = cancel the installation in case the preservation of an existing partition with the label data is not possible with the given partition data.
if_possible = an existing partition with the label data is preserved if possible according to the given partitioning parameters. Otherwise it will be deleted.
never = a new partition table will be created. (default=never) -

9.5.8. opsi-linux-client-agent
The opsi-client-agent for Linux is part of the cofunding project Linux Agent, which is liable to pay costs.
The opsi-client-agent for Windows is based on two components:
-
the service
opsiclientd -
the action processor
opsi-script / opsi-script-nogui
The opsi-client-agent for Linux is based on the Linux port of the Windows client agent.
The opsiclientd is not ported to all supported Linux distributions.
If no opsiclientd is available, it is substituted by a direct opsiscriptstarter call.
A Linux opsiclientd is available for:
-
Debian 9 / 10 / 11
-
Ubuntu 18.04 / 20.04
-
Linux Mint 20-1 / 20-2
-
openSuse 15.1 / 15.2 / 15.3
-
RedHat 7 / 8
-
CentOS 7 / 8
-
SLES 12 / 12SP1 / 12SP2 / 12SP3 / 12SP4 / 15 / 15-1 / 15-2
-
UCS 4.4
If there is no opsiclientd, so it is replaced by the opsiscriptstarter, which performs the following opsiclientd tasks at system start:
-
connect to the opsi-server: check whether actions are to be performed
-
mount the depot share
-
start the action processor
-
unmount the depot share
-
transfer the logfile to the server
The Linux action processor is named opsi-script and is built from the same sources as the Windows opsi-winst. So on Linux the same scripting syntax is available as on Windows. All common features, that are not Windows specific, are available, as there are e.g.:
-
file handling
-
string and stringlist functions
-
executing external scripts and programs
-
communication with the opsi-Server
-
patching config files
Of course Windows specific features (like patching the Windows registry) are not available on Linux, but there are some additional Linux specific functions like e.g.:
-
getLinuxDistroType
-
getLinuxVersionMap
Logging of the opsi-script ist available (like with the opsi-winst on Windows).
Linux opsi-script is available as a graphical version for working with X-Windows and a noGUI version for systems without graphical user interface.
opsi-linux-client-agent: Installation: service_setup.sh
This method is the first choice for installations on a single computer. service_setup.sh can also be used for maintenance or repair of a client. For mass roll-out, see the chapter below.
-
login to the Linux client with root privileges
-
mount the shared directory on the opsi server at \\<opsiserver>\opsi_depot to any mount point
-
change to directory
opsi-linux-client-agentat the mountpoint -
start as this place the script
./service_setup.sh
The script connects to the opsi-webservice in order to create the server side client information and to get the pckey. The connection requires the user/password combination registered in the config.ini. If the connection fails, a login window pops up (or commandline questions), where the user can fill in a URL, user, and password. The provided user has to be a member of the group opsiadmin.
| After the installation, the client will be restarted |
opsi-linux-client-agent: Installation: opsi-deploy-client-agent
The opsi-deploy-client-agent installs the opsi-client-agent directly from the opsi-server to the clients.
Requirements for the opsi-server:
-
The Python package paramiko has to be installed. It is available as
python-paramikoon most distributions and can be installed through the corresponding package manager. In the fugure, opsi-deploy-client-agent will be shipped as binary, such that there are no more external dependencies.
Requirements for the clients are:
-
ssh access as root or as a user that has the possibility to run sudo
When using opsi-deploy-client-agent 4.1.0.1 or older with a non-root user this has to have the possibility of executing sudo non-interactively.
|
The program creates the client on the server, then copies the installation files and the configuration information including the pckey to the client. After copying the necessary information, opsi-deploy-client-agent starts the installation on the client.
With opsi-deploy-client-agent a whole list of clients can be processed.
These can include any number of clients that can be passed as the last parameter, or with the option -f by which the clients can be read from a file.
When using a file, on each line a client must be present.
The program can work with IP addresses, host names and FQDNs. It will automatically try to recognize what kind of Address was passed.
The program can be found at /var/lib/opsi/depot/opsi-linux-client-agent
Run the program with root privileges.
It could happen that you must first make the program executable with:
Chmod u + x /var/lib/opsi/depot/opsi-linux-client-agent/opsi-deploy-client-agent
Please note that for the installation via opsi-deploy-client-agent, the values of ProductProperties (if the client is already registered) do not have any effect.
This is because a connection to the backend can first be established during some part of the deployment. In the unusual case that a client is already registered and
still the deploy program is used to roll out the opsi-linux-client-agent and non-default settings while desiring to set non-default settings, it is recommended to set
opsi-linux-client-agent to setup after successful application of the deploy program. This way the desired productProperties take effect and override the defaults.

If you install a Linux via opsi netboot product, you only have to switch the property install_opsi-client-agent to true (which is the default) in order to install the opsi-linux-client-agent.
opsi-linux-client-agent: opsiclientd configuration
The opsiclientd for Linux is a port of the opsiclientd for Windows.
So it works withe similar configuration file which is located at:
/etc/opsi-client-agent/opsiclientd.conf.
A detailed description of this file you will find at the chapter for the opsi-client-agent for Windows: Section 6.1.3.6, “Configuration”
At the moment there are not all of the features and events available on Linux.
Available are:
-
Start at boot time (or via explicit start of the service
opsiclientd). At Linux is the name of this eventopsiclientd_start(notgui_startup) -
event_on_demand -
The
event_timerbut only with the configuration:super = default
Not available are:
-
Everything that is related to local caching (WAN-Extension).
-
Modification of events via

9.5.9. opsi-linux-client-agent: Known Bugs
Copy a bundle of files via Files section from a smb share may fail according to the Samba version This problem was reported from some samba3 Versions but seems to be vanished in samba4.
Workaround: Instead of:
[Files_copy_netboot]
copy -s "%scriptPath%/installfiles/*" "$target$/installfiles/"you may use:
[ShellInAnIcon_opsi_copy_netboot]
set -x
export PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin
cd "%scriptPath%"
tar cf - installfiles | ( cd "$target$/installfiles/" ; tar xf - )Script examples
For software deployment on Windows clients there can be said: the installation of software itself is as important as the subsequent configuring of the software.
On Linux most packets are available from the distribution repositories. So the installation part is less, but the configuration part stays the same. Also there are applications, that are not available from the standard repositories.
In this case special repositories or installation sources have to be added to the system. The important feature is, that all installation and configuration settings can be managed and logged on the opsi-server.
Here are some example snippets for an opsi-linux-client-agent opsi-script:
-
exit in case the script detects a non Linux system
-
detecting the distribution type (to use
apt,zypperoryum) -
detecting the Linux version
-
installing a packet
-
adding a repository
Example: exit in case the script detects a non Linux system:
[Actions]

Here some localboot products that are part of the standard opsi Linux support.
The product l-opsi-server
The product l-opsi-server serves to install on a Linux computer an opsi-server via opsi-linux-client-agent in an automated way. This can serve to install quickly a new opsi-depot-server or e.G. an opsi Test system.
|
Currently for a opsi-config server an other maschine can’t be a opsi-linux-client and a opsi-depot-server at the same time. To work around this limitation, you have two possibilities: 1. Using one opsi-config-server: After the installation of opsi via l-opsi-server and before you register this maschine as opsi-depot-server, you have to delete it as client in the configed. 2. Using two opsi-config-servers: Setup a second independent opsi-config-server, which is only used to administrate (install and mantain) your opsi-servers. So this second opsi-config-server knows the other opsi-servers only as linux-clients. Your other (first) opsi-config-server know theses other opsi-servers as depots. In a UCS environment method 2 is recommended and the second opsi-config server must not be a UCS Server. |
The product l-opsi-server has the following Properties:
-
opsi_online_repository:
(Base-) Repository for opsi-server installation.
(Default="https://download.opensuse.org/repositories/home:/uibmz:/opsi:/4.2:/")
see also repo_kind -
opsi_noproxy_online_repository:
(Base-) Repository for opsi-server installation (without any cache proxy).
(Default="https://download.opensuse.org/repositories/home:/uibmz:/opsi:/4.2:/")
Should you require onopsi_online_repositoryto introduce a Proxy or deb-cacher (e.G. 'http://mydeb-cacher:9999/download.opensuse.org/repositories/home:/uibmz:/opsi:/4.2:/"), than introduce the URL without Proxy. Otherwise introduce the same asopsi_noproxy_online_repository. -
repo_kind:
Which kind of repository ["experimental", "stable", "testing"] should be installed ?. (Default=stable)
With the Client OS, opsi_online_repository and repo_kind the URL will be built and the client will be added to an opsi repository. -
backend:
Which backend should be installed ? (mysql needs a valid activation file). (Default=file)
A modules file with the require Activations can be stored in the custom directory of the product. If a modules file is found there, then will this one used. -
opsi_admin_user_name:
The name of the opsi_admin_user to create (empty= nothing created). (Default=adminuser)
If a user is introduced here, it will applied, also it will be added to the group opsiadmin, pcpatch/opsifileadmin and become as unix and samba password the valueopsi_admin_user_password -
opsi_admin_user_password:
What is the password of the opsi_admin_user to create (empty= not allowed). (Default=linux123)
seeopsi_admin_user_name -
setup_after_install:
Which opsi product(s) should we switch to setup after l-opsi-server installation is done ?. (Default="") -
allow_reboot:
May the server reboot if script is finished ?. (Default=true) -
install_and_configure_dhcp:
Should we run the dhcp server on this machine ?. (Default=False)
If this property is false then the following properties: netmask, network, dnsdomain,nameserver and gateway are meaningless because they are only used for dhcp configuration. -
myipname:
Set a different IP name (FQDN) (auto= use standard) (Default=auto)
Meaningless if install_and_configure_dhcp=false -
myipnumber:
Set a different IP number (auto= use standard) (Default=auto)
Meaningless if install_and_configure_dhcp=false -
netmask:
Netmask (for dhcp). (Default="255.255.0.0")
Meaningless if install_and_configure_dhcp=false -
network:
network address (for dhcp). (Default="192.168.0.0")
Meaningless if install_and_configure_dhcp=false -
dnsdomain:
DNS domain (for dhcp). (Default="uib.local")
Meaningless if install_and_configure_dhcp=false -
nameserver:
Primary nameserver (for dhcp). (Default="192.168.1.245")
Meaningless if install_and_configure_dhcp=false -
gateway:
gateway (option routers for dhcp). (Default="192.168.1.245")
Meaningless if install_and_configure_dhcp=false -
ucs_master_admin_password:
Only needed for opsi installation on UCS Server with other Roles than Role Master. (Default=linux123) -
update_test:
Do not use: Internal Debugging. (Default=False) -
ucs_master_admin_password:
On a UCS machine the roles Slave, Backup and Member have to be joined correctly with the Mas ter. This property takes the password to perform the join.
The product has setup required before dependency to the product l-system-update. That means when you set l-opsi-server on setup it will also automatically set l-system-update also on setup and installed before.
In the directory custom of the product l-opsi-server the activated file (modules) is stored, which is used in the Installation of the product l-opsi-server and will be preserved in the case of a new version of the product.
l-os-postinst
This product installs and configures those parts of the base installation, that cannot be done from the bootimage in a proper way.
This is for the different distributions:
-
CentOS:
-
installation of SELinux
-
This product has a dependency to the product l-system-update which is executed before running l-os-postinst.
This product has a high priority, so it is executed before common products.
l-desktop
The product l-desktop installs a desktop packet on the computer.
The property desktop selects the desktop to be installed. Not all of the desktops are available for every distribution. For instance Unity is available for Ubuntu only. If the selected desktop is not available, the distribution specific default desktop will be installed. Furthermore the scope of the desktop packets differs according to the distribution and the selected desktop. It can be just the actual desktop software, or might also contain some base products like libreoffice, firefox, PDF Reader etc.
The property desktop can have the following values:
-
Gnome
Default for Debian, CentOS, RHEL.
Available for all distributions. -
KDE
Default für SLES, OpenSuse. Available for all distributions. -
Unity
Available for Ubuntu only. -
Cinnamon
Available for Ubuntu only. -
xfce4
Available for Ubuntu, Debian. -
lxde
Available for Ubuntu, Debian.
l-system-update
This product updates the system.
l-swaudit
Software inventory, based on the packet manager
l-hwaudit
Hardware inventory.
The hardware inventory currently is based on the Python implemented method as also used by the bootimage. Therefore the packet python-opsi from the opsi-repository of the distribution must be installed. So if there is no opsi-repository available for this distribution, the hardware inventory fails.
l-jedit
Java based editor with syntax highlighting for opsi-script. If Java is missing on the system, it will be installed automatically.
9.5.11. Inventory
To create an inventory, the data are collected on the client and sent to the server. The hardware inventory is based on the methods implemented in the bootimage.
The software inventory is based on the data from the packet management of the deployed Linux distribution.
9.5.12. UEFI / GPT support
Most of the opsi 4.1 / opsi 4.2 Linux netboot products are UEFI/GPT compatible.
9.5.13. Roadmap
Linux support is a brand new opsi feature. Therefore not all of the planned features have been implemented yet with the first release.
Planned features to follow are:
-
configurable partitioning
-
logical volume management
-
patching XML files
-
patching hierarchical configuration files like dhcpd.conf

9.6.3. Preconditions for working with UEFI / GPT
This module currently is a
co-funded opsi extension.
Some preconditions are required to work with that module, which is to get a suitable modules file to unlock the feature. You can get this unlock file by purchasing the extension module. For evaluation you can get a time limited modules unlock file without charge. ( → mail to info@uib.de).
Technical requirements are opsi 4.1 with package versions:
| opsi package | version |
|---|---|
Netboot products |
>=4.1 |
opsi server packages |
>=4.1 |
opsipxeconfd |
>=4.1.1.20-3 |
opsi-linux-bootimage |
>=20200506 |
9.6.4. Furher remarks regarding the pxe-installation with the opsi-Moduls UEFI / GPT
-
opsi supports only 64-Bit UEFI-Installations
-
PXE-boot installs require a winpe that is capable of booting in UEFI mode. Often, an existing winpe will be capable of doing so, check by verifying there is a folder named
EFI, as well as a file namedbootmgr.efiinside your winpe folder. If that is not the case, create a recent winpe as explained in our opsi-getting-started Manual, Chapter "Creating a PE". A winpe, that is UEFI capable, needs to reside in the winpe_uefi folder of the opsi netboot product. Provided your winpe is already capable of booting UEFI and MBR modes, you could simply place a softlinkwinpe_uefi>winpe. -
you have to configure your external DHCP server with the bootfile
linux/pxelinux.cfg/shimx64.efi.signed -
Activate in the opsi-configed the checkbox "Uefi-Boot" for uefi-clients (since version 4.0.5.8.1) or set hostparameter
clientconfig.dhcpd.filename=linux/pxelinux.cfg/shimx64.efi.signedThis setting can also be made via the following command line call:opsi-admin -d method configState_create "clientconfig.dhcpd.filename" "here.host.id" "linux/pxelinux.cfg/shimx64.efi.signed"
If your opsi server had earlier versions of the package requirements installed you might need to edit the file /etc/opsi/opsipxeconfd.conf. The change involves the line uefi netboot config template x64 = /tftpboot/linux/pxelinux.cfg/install-elilo-x64.
This line has to be changed to uefi netboot config template x64 = /tftpboot/linux/pxelinux.cfg/install-grub-x64 to ensure a compatability between the UEFI bootloader and the named pipe.
|
-
BIOS settings:
Since the BIOS menus are very different and use different terminology, you need to consider here what is the best fit for your BIOS.-
Secure Boot disabled
This entry is usually in the Boot or Startup but it can also be found in the Security area. Information about using secureboot can be found in a different chapter. -
Turn the BIOS on in the UEFI-Mode.
If you have the choice between UEFI only, Legacy only or Both you should select UEFI only. If the selected option is Both this is not the best practice but it can eventually work. If the Legacy Support it is present, it should be disabled. CSM Support in conjunction with UEFI only can remain enabled. Otherwise just disable it. UEFI Network Boot must be enabled. It could happened that the entry is also named Network Stack and also can be found under the UEFI category. If there are two categories for IPv4 and IPv6 here the right choice is IPv4.
-
9.6.5. Introduction
Recent PCs, tablets and server often are equpped with an UEFI BIOS. Often there is a legacy mode available to support the old features including PXE boot. But more and more devices come with an UEFI only BIOS (especially tablets). So they cannot be managed with the previous opsi environment.
To integrate these devices into opsi and to be able to use the advantages of UEFI, the uib gmbh developed the opsi extension for UEFI support.
9.6.6. What is UEFI and what is different about it?
UEFI is the abbreviation of Unified Extensible Firmware Interface and is the follow-up to the classic PC-BIOS (MBR-BIOS).
For detailled information on UEFI there are some links listed below.
UEFI has much more features than the old BIOS. Basically UEFI is a small operating system by itself. But in this place, we just consider some features, that are of special interes to the system administrator:
-
The recent (by January 2014) implementations of UEFI by the hardware manufacturers have not developed any clear standards yet. As soon as the system is to be booted from any other device but the hard disc, you face the utter chaos. Often UEFI and classic BIOS are implemented both, sometimes they can be deactivated individually, or sometimes not. UEFI can be implemented with the Compatibility Support Module (CSM), or without. Netboot might work, or might not.
Especially the availability of netboot is essential for structurd client management. -
With the classic PC-BIOS the BIOS and its configuration usually are separated from the operating system. So BIOS configurations like the boot sequence cannot be changed by the operating system.
This is different with UEFI. The operating system can change the boot sequence (and usually it does). This has consequences for a client management that relies on netboot. -
UEFI comes with its own boot manager, which not only can be used by the operating systems to change the boot sequence, but also contains the start entries for the operating systems themselves. This is to support the parallel installation of different operating systems, so that there is no conflict with the different boot loaders.
-
UEFI can be implemented for 32 or 64 bit, which has to match a 32 or 64 bit operating system. A 32bit OS can not be installed on a 64 bit UEFI system.
-
Secureboot allows only authorized systems to boot.
-
partitioning with GPT and additional partitions for the bootloader:
-
1. partition: EFI system partition (ESP) 100 - 260 MByte ; VFAT
-
2. partition: Microsoft reserved (MSR) 32 - 128 MB; NTFS
-
following the actual OS partitions
-
Links :
9.6.7. What is different about GPT
GPT (GUID Partition Table) id the follow-up for the previous MBR partition tables. GPT is part of the UEFI specification.
- The main features for the sysadmin are
-
-
overriding the 2 Terabyte limit (now it is 8 Zebibyte)
-
almost unlimited number of primary partitions
-
changed partition types / GUIDs
-
new: partition GUIDs
-
new: partition attributes (hidden, read only, …)
-
different tools: gdisk
-
Basically GPT can be used without UEFI. But UEFI depends on GPT. With UEFI there are up to two additional partitions:
-
the EFI system partition (ESP) with the bootloaders
-
Microsoft reserved (MSR)
Links :
9.6.8. UEFI Boot
In contrary to the old BIOS the boot sequence not only can be defined for devices, but also can be set for different bootloaders on the EFI system partition. Furthermore the sequence can be changed by a running operating system. So if you set netboot as the first boot priority, this setting will not survive the first OS installation.
9.6.9. UEFI Netboot
Unfortunately early UEFI implementations do not support netboot at all, but netboot support is increasing.
With the UEFI support extension module uib gmbh has developed a succesfull UEFI netboot support for integrating UEFI clients into opsi. Because the UEFI standard is still under development and changing, in future the opsi UEFI module will continue to adapt to the technical changes, which might require structural redesigns of the module.
9.6.10. opsi support for UEFI netboot
The opsi support for UEFI is based on several components:
-
adaption of the netboot UEFI bootloader GRUB2 to the opsi / client-management requirements.
-
new opsipxeconfd, which also supports config files for the opsi-GRUB2 (in addition to the PXE config).
-
new (64 bit) opsi-linux-bootimage with the tools for UEFI- and GPT management
-
redesigned netboot products for OS installation (Windows/Linux) with additional support of UEFI/GPT (of course only for OS that support UEFI).
-
client setting on the opsi-server whether to be treated as UEFI client or not. (clientconfig.dhcpd.filename=linux/pxelinux.cfg/shimx64.efi.signed)
-
support of a software-controlled switch to UEFI netboot.
The label of the UEFI netboot entry of the firmware can be saved on the opsi-server (clientconfig.uefinetbootlabel), as far as the firmware supports it (there is an activatable netboot entry in the EFI). This allows opsi-products to use netboot for the next reboot. This technique is implemented in several opsi products. An important example is the productopsi-uefi-netboot:
This product tries to configure the UEFI for netboot and then triggers a reboot. If there is nouefinetbootlabelor the client is not an UEFI client only a reboot is triggered.
This product is available for Windows and for Linux.
9.6.11. Installation
All packages required are installed automatically with opsi version 4.0.5.
9.6.12. Configuration of a Linux DHCP server
Configuration example of a Linux isc-dhcp-server:
filename "linux/pxelinux.0";
# this is the UEFI detection:
if substring (option vendor-class-identifier , 19,1 ) = "0" {
log (info, "pxe client");
filename "linux/pxelinux.0";
}
else if substring (option vendor-class-identifier , 19,1 ) = "6" {
log (info, "efi32 client");
filename "linux/pxelinux.cfg/elilo-x86.efi";
}
else if substring (option vendor-class-identifier , 19,1 ) = "7" {
log (info, "efi64 client");
filename "linux/pxelinux.cfg/shimx64.efi.signed";
}
else {
log (info, concat ( "Unhandled vendor class Arch: ", substring (option
vendor-class-identifier , 19,1 )));
}
See also: Fedora: PXE Boot Configuration
Example for the configuration of a Windows DHCP server 2012 R2
-
As standard for this variant the PXE boot file for x64 Uefi installations is entered as default. DHCP options 66 and 67 are adjusted as it follows:
066 Host name of the start server: <IP of the opsi server>
067 Name of the start file: linux/pxelinux.cfg/shimx64.efi.signed -
To distinguish the Bios clients, a manufacturer class identifier (PXEClient:Arch:00000:UNDI:002001) must be defined on the DHCP server:
Define manufacturer class
Add new manufacturer class
Edit class
Display name: Legacy BIOS
Asci: PXEClient:Arch:00000:UNDI:002001
-
The predefine options must be order under the manufacturer class:
Set predefined options
Options
Option class: Legacy BIOS
Add
Adjust the option type
Name: Legacy BIOS
Data Type: String
Code: 60
Description: PXEClient Class Legacy BIOS
Predefined options and values
String: PXEClient
-
Define the DHCP policy that is assigned to the boot file for the PXE boot (BIOS) of the manufacturer class:
New policy
Policy Name: PXE BootFile Legacy BIOS
continue
Add conditions
Criteria: Manufacturer class
Operator: equals
Value: Legacy BIOS
add
Would you like to configure an IP address range for the following policy: No
Manufacturer class: DHCP Standard Options
067 Name of the start file
file input
String value: linux/pxelinux.0
-
In the range options, there are two entries for the start file, which is linked to a policy in case a bios client is detected:
067 Name of the Start file: linux/pxelinux.cfg/shimx64.efi.signed Policy: None 067 Name of the Start file: linux/pxelinux.0 Policy: PXE BootFile Legacy BIOS
Configuration of a UCS Dhcp-Server
The following information comes from Univention itself:
https://help.univention.com/t/how-to-configure-a-dhcp-switch-for-uefi-and-non-uefi-boot/9931
9.6.13. opsipxeconfd configuration
Since opsipxeconfd 4.0.7.7 it is possible to configure the path of the files used as templates for UEFI netboot in the configuration file opsipxeconfd.conf.
This is possible through the options uefi netboot config template x86
and uefi netboot config template x64.
9.6.14. Criteria for a good BIOS
Whether an UEFI BIOS meets the requirements of a client management system like opsi depends on several criteria. These criteria do not estimate the qualitiy of the device, but only whether it can be managed by using netboot. This requires BIOS functions for UEFI netboot. Hier an example comparison:

In this case activatable entry means, that for the next reboot a netboot can be activated by standard software. netboot without interaction means, that an activated netboot will be executed at the next reboot without any require4d interaction (like pressing any key combinations, F12 key, …). If these preconditions are met, special opsi products can trigger a netboot. This feature is very important for automated processing. A product using this feature is for instance the localboot product for Windows and Linux opsi-uefi-netboot.
9.6.15. Technical details
The following sub chapters provide some information for scripted or manual handling of UEFI / GPT. For understanding how opsi works with UEFI/GPT, knowing these details is not required.

Technichal details about GPT
GPT partitions know some new partition types. These are derived from the standard types. So the partition type for NTFS 07 becomes GPT 0700. The Linux partition types 82 and 83 become 8200 and 8300.
The list of known partition types can be shown:
# sgdisk -L

fd00 Linux RAIDActually the partition types shown in this list are just short forms for the actual GUIDs that are used. The partition schema is named after that.
So:
0700 stands for Microsoft basic data and for the GUID EBD0A0A2-B9E5-4433-87C0-68B6B72699C7
A list of GUIDs can be found at Wikipedia:
Furtheron the tool gdisk (and sgdisk, …) has an internal substitution table for unknown partition types. For the old partion type for vfat32 0b there is no corresponding 0b00. By passing the type 0b00 to sgdisk, it will be translated to 0700 without any message. Perhaps because of the consideration: vfat32 - this must be some Microsoft data partition …
GPT partitionen can have attributes.

UEFI 32 Bit support

other netboot capable UEFI boot loader (grub2)
9.7. opsi with secureboot
OEM manufacturers deliver an additional layer of security with secureboot (sometimes written as secure boot). With secureboot only authorized Software and operating systems can be installed on a machine. This authorization is implemented directly via a key query to the UEFI. As long as the used keys match the operating system and software the usage will be authorized. The key inside the UEFI capable machines was created by Microsoft and the OEM manufacturer. Therefore any loaded efi binary or kernel has to be signed off by one of those keys. A chain of trust verifies that every loaded efi binary or kernel has a correct signature.
This module currently is a
co-funded opsi extension.
Some preconditions are required to work with that module, should be dully noted that a suitable modules file is needed to unlock the feature, and also the prerequired module.
You can get this unlocked modules file by purchasing the extension.
For evaluation purposes we can provide you with an evaluation modules file free of charge. (→ mail to info@uib.de).
9.7.1. Requirements
The technical requirements are as follows (with package versions):
| Package | Version |
|---|---|
opsi-linux-bootimage |
>= 20190923-4 |
opsipxeconfd |
>= 4.1.1.15-1 |
9.7.2. Further remarks for the usage of the secureboot module
Secure boot is only possible on clients that support this feature as part of their firmware. The installation of a client with secureboot is only supported on 64-bits.
UEFI Netboot installs require a winpe that is capable of booting in UEFI mode.
Often, an existing winpe will be capable of booting in such way, to verify it check if there is a folder named EFI, as well as a file named bootmgr.efi inside your winpe folder.
If that is not the case, create a UEFI compatible winpe as explained in our opsi-getting-started Manual, Chapter "Creating a PE".
The winpe, that is UEFI capable, needs to be located in the winpe_uefi folder of the opsi netboot product.
If your winpe is already capable of booting UEFI and MBR modes, you could simply place a softlink winpe_uefi > winpe.
9.7.3. opsi server configuration for secureboot clients
If you have an external DHCP server you have to configure it so it forwards an UEFI Netboot to your opsi-server.
The bootfile has to be: linux/pxelinux.cfg/shimx64.efi.signed
Activate the "Uefi-Boot" checkbox in the opsi-configed for uefi clients. Alternatively you can run the following command:
opsi-admin method configState_create "clientconfig.dhcpd.filename" "<insert host id here>" "linux/pxelinux.cfg/elilo.efi"
Using the file elilo.efi via the opsi-admin command only serves the purpose to set the UEFI checkbox within the opsi-configed.
This has no relation to the usage of the dhcp bootfile.
The opsi-configed will feature a secureboot checkbox and accept the proper filename in a future release.
|
In addition the UEFI template for UEFI clients has to be changed in the configuration file of the opsipxeconfd.
The specific uefi netboot config template x64 must have the value /tftpboot/linux/pxelinux.cfg/install-grub-x64.
We recommend to run the opsi-setup --init-current-config command after this change.
All UEFI clients will boot the Microsoft signed file shimx64.efi.signed which is provided by the opsi-linux-bootimage package.
Clients with activated secureboot verify the signature and load the grub2 bootloader file.
Non secureboot clients fail this verification and also load the grub2 bootloader.
Either way both type of clients load the shimx64.efi.signed file.
The installation itself doesn’t differ in secureboot and non secureboot mode.
Clients successfully installed in secureboot mode can be checked with the command msinfo32.
The output contains an entry secureboot.
9.7.4. Client configuration
| Please keep in mind that terms might change depending on manufacturer and hardware model, |
The UEFI of the client should be configured as following:
-
Secureboot enabled
This entry is most commonly found in the section Boot, Startup of Security. -
Run the BIOS in UEFI mode.
If you have a choice between UEFI only, Legacy only and Both choose UEFI only Deactivate Legacy Support as Secure Boot only works on a UEFI only setup. CSM Support in combination with UEFI only can be left activated. In case of doubt deactivate the CSM Support feature. UEFI Network Boot needs to be activated. This entry can also be called UEFI Network Stack. If your machines UEFI gives you a distinction between IPv4 and IPv6, IPv4 is the choice to make.
9.8. opsi local image
9.8.1. Requirements for the opsi extension opsi local image
This module is currently a
cofunding project.
Some conditions have to be met to use this module. This means that you need an activation file to use it. You will receive this activation if you buy the extension. For evaluation purposes, we also provide a time-limited activation free of charge (→ mail to info@uib.de).
Further details can be found in Section 9.1, “Activation of non-free modules”.
With the permission to use opsi-local-image you also acquire the right to use the extension opsi-vhd-reset (see Section 9.9, “opsi vhd reset”).
A technical requirement is opsi 4.0.3 with package versions:
| opsi package | version |
|---|---|
opsi-linux-bootimage |
>= 20130207-1 |
For the product opsi-local-image-capture the share opsi_depot_rw must have write permission for pcpatch. Check your Samba configuration.
|
9.8.2. Introduction
Opsi offers a good basis for the automated installation and maintenance of Windows computers - especially when it comes to heterogeneous hardware. The package-based installation technology supported by opsi is not fast enough to use computers in training rooms within a short time, e.g. to put it back into a defined state during a break between two courses. Therefore, a concept is presented here in which the package-based installation is saved locally on a second partition as an image copy and from there a quick recovery is possible.
-
Initial installation finishing with a local image backup
-
Fast recovery based on different techniques
-
System maintenance finishing with a local image backup
-
Integration of capturing of existing installations to WIM
-
Integration of Linux clients in the Backup/Restore process.
9.8.3. Concept
The requirements of educational computer networks differ in part from those of other networks. An essential requirement, which is discussed in the following part, is the quick restoration of computers to a defined state, which has been changed because of a temporary use. Specifically, it is about the provision of computers in class rooms, whereby the problem also applies to commercial computer rooms or university computer pools.
The restore should take place within a short time (approx. 15 minutes) and should, as far as possible, not only reset a computer but also switch to another base installation (e.g. Win XP / Win 7 / Linux).
It must also be possible to ensure that the systems are continuously updated with security updates.
The usual techniques for installing PCs have several specific advantages and disadvantages:
| Feature | Unattend | Image |
|---|---|---|
Performance |
(-) slow |
(+) fast |
Sensitivity to heterogenous Hardware |
(+) low |
(-) high |
Network load |
(-) high |
(-) high |
The concept of opsi-local-image tries to combine the advantages of both approaches:
| Feature | Unattend |
|---|---|
Performance |
(+) fast |
Sensitivity to heterogeneous Hardware |
(+) low |
Network load |
(+) low |
The concept can be summarized in the following key points:
-
Initial Windows installation via PXE boot, package-based with individual driver integration using the opsi-Linux-Bootimage
-
Store this initial installation in a backup image on another partition on the local hard drive using the opsi-Linux-Bootimage
-
Quick restore the productive installation from the local image using the opsi-Linux-Bootimage
-
Maintenance of the local installation (security updates) via the opsi software distribution and backup of the updated system to the local backup image using the opsi-Linux-Bootimage
9.8.4. Technical Concept
The workstation is used with a static partition table. You can work with either 3 or 4 partitions:
-
Partition 1 (System)
Holds the currently used operating system (Windows / Linux)
The size of this partition is set during partitioning via a property of the productopsi-local-image-prepare. -
Optional: Partition 2 (sysdata)
This can be for example be used to store user data, which is not overwritten during a restore. The formatting is NTFS.
The size of this partition is set during partitioning via a property of the productopsi-local-image-prepare. -
Partition 3 (winpe / swap)
The size of this partition is static and set to 4GB.
This partition is not used on Windows XP.
On NT6 (Windows 7) this partition is used for the winpe required during installation and is not visible during normal operation.
On Linux this partition is used as swap. -
Partition 4 (backup)
This partition is used to store the backup images and their metadata.
The size of this partition is the free space still available after the other partitions have been created.
The netboot products for operating system installations use only the first two or three partitions (XP uses only the first) and leave the last backup partition untouched. This means that the images on partition 4 (backup) are retained even when installing a new operating system.
9.8.5. Process steps
Initial Installation
The necessary static partitioning is first created using the product opsi-local-image-prepare.
Then the products opsi-local-image-win* or others can be used to install several operating systems with different configurations and different application software.
By default, these are automatically saved as an image after installation.
Restoring an image
Executing the product opsi-local-image-restore automatically restores the last created image. If a different image is to be restored, this has to be specified in the property imagefile.
Deleting an image
By executing the product opsi-local-image-delete, the image specified in the property imagefile will be deleted.
Updating an image: automatic work flow with opsi-auto-update
opsi-auto-update is a product to simplify the maintenance of the clients.
In essence, this product can be used to ensure that the installed products are up to date.
The product sets all installed products,
whose version is not identical to that on the server,
for the client to setup.
Since this product can not only be used in the context of opsi-local-image, it is described in the chapter opsi standard products / opsi-auto-update:
Section 8.1.1.19, “opsi-auto-update”
9.8.6. The opsi-local-image products
The opsi-local-image products from version 4.1 also support systems with more than one harddisk. Please also note the section Section 8.2.3, “Some hints to the NT6 netboot products (Win7 to Win 10)”
The opsi-local-image package consists of the following products

Executing opsi-package-updater --repo uib_local_image install will then install the new products.
UEFI Compatibility
The opsi-local-image products are compatible with UEFI.
netboot product for partitioning
-
opsi-local-image-prepare
Creatopm of the static partitioning of the harddisk for all other products.
Properties:- ask_before_inst
-
Determines if the start of the installation has to be confirmed on the client. (Default=true)
- system_partition_size
-
Determines the size of partition 1 (system). (Default = 30G)
- data_partition_size
-
Determines the size of partition 2 (data). If set to 0G, no partition will be created for data. (Default = 0G)
- start_os_installation
-
The product to install an operating system can be selected here, which is started automatically after the partitioning. When installing any of these products, the product properties imagefile and imagefiles_list are deleted for the product
opsi-local-image-restore, as this data has become invalid due to the repartitioning. - delay_for_reboot
-
Seconds between the end of the script and the reboot to give the server time to create the netboot pipes.
- minimal_backup_partition_size
-
This property is used to check if the size entries make sense.
The size of the backup partition results from:
Harddisk size - (system_partition_size+data_partition_size+winpe_partition_size).
Usually opsi-local-image is used because a local backup of the system partition is to be made. This requires that there is enough space for the backup partition. If, during the calculation of the partitioning, it is determined that the remaining space for the backup partition is smaller than the value ofminimal_backup_partition_size, the process is aborted.
(Default=55%) - winpe_partition_size
-
Size of the winpe partition (Default=4G)
- multi_disk_mode
-
This property is used to select the target disk of the installation.
Possible values are: "0", "1", "2", "3", "prefer_ssd", "prefer_rotational"
The values "0", "1", "2", "3" indicate the direct index of the harddisk ("0"= first harddisk)
The value "prefer_ssd" selects the first SSD.
The value "prefer_rotational" selects the first classic (rotational) disk.
This property is ignored on systems with only one disk.
Default = "0" - backup_partition_on_same_disk
-
true : create the backup partition on the system disk. false : create the backup partition on the first disk that is not the system disk.
This property is ignored on systems with only one disk.
Default = "true"
| Use this product only for the initial preparation of the disk. It deletes all existing images. |
netboot products for the installation of Windows
The special netboot products for installing Windows are derived from the opsi standard products for installing Windows. Specifically, this means that they are identical in terms of structure and driver integration. Corresponding instructions can be found in the opsi-getting-started manual.
The properties of the Windows NT6 products from version 4.1 are a subset of the properties of the standard NT6 products as described in the Section 8.2.3, “Some hints to the NT6 netboot products (Win7 to Win 10)” section. The missing properties for disks and partitions are taken from the product opsi-local-image-prepare.
- ATTENTION
-
Do not change the property values of opsi-local-image-prepare after you have prepared the machine with it, as subsequent products will access these values.
-
opsi-local-image-winxp
Installation of Windows XP. Uses the first partition only. Administrator password is empty. -
opsi-local-image-win7

Netboot products for backup and restore
-
opsi-local-image-backup
This product backs up the operating system currently installed on partition 1 in an image file on partition 4. The name set in the product property is used as the name for the image. If this is empty, the name of the opsi netboot product is used, which is currently set to installed (e.g.opsi-local-image-winxp). This name is set for the productopsi-local-image-restoreas the product property imagefile, so that a subsequent call to` opsi-local-image-restore` will restore exactly this image by default. This name is added to the product property imagefiles_list for the productopsi-local-image-restore. This property contains the list of all available images. Furthermore (for the Windows products) the current opsi product versions are saved together with the image so that they can be restored as part of the restore.
The backup tool which is used is partclone.

Name of the image file to be created (default = empty = the name of the currently installed opsi-local-image product will be used). The name may contain spaces but no umlauts/tremas. (In the case of spaces, these are treated internally as underscores, i.e. my image = my_image.) -
setup_after_install
One or more products can be specified here, which are set to setup after the operating system installation is complete. The dependencies of these products are also resolved.
-
-
opsi-local-image-restore
This product restores the image specified in the imagefile product property to partition 1 and marks it bootable. Furthermore (for the Windows products) the opsi product versions saved with the image are restored together with the image.
Properties:-
askbeforeinst:
Determines if the start of the installation has to be confirmed on the client. (Default=true) -
architecture:
Architecture selection, determines the selection of the bootimage and the installation architecture. (Default=64bit) -
imagefile
Name of the image to be restored. The value of this property has automatically been set by the last backup. The list of available images can be found in the propertyimagefiles_list. -
imagefiles_list
List of the available images. This list is maintained by the backup product. -
update_and_backup
The use of this property is discouraged
Instead, use the productopsi-auto-update. This product is described in the chapter opsi standard products / opsi-auto-update:
Section 8.1.1.19, “opsi-auto-update”
(true/false) Default = false. If set to true, after the restore, it is ensured that all localboot products that are available on the server in a different version are set tosetupand the product` opsi-local-image-backup-starter` is set toonce. This means that all existing updates are installed and a backup is created automatically after the updates. -
setup_after_restore
One or more opsi products can be specified here, which are set to setup after the restore is completed and are therefore automatically installed after the reboot. The default is the product windomain to add the restored client to the Windows domain again.
-
-
opsi-local-image-delete
This product deletes the image given by the product property imagefile from the backup partition-
imagefile
Name of the image to be deleted (default = empty, results in an error when executing)
-
Localboot products for process control
-
opsi-local-image-backup-starter
This localboot product sets the Netboot productopsi-local-image-backupto setup and reboots the client. This product has a very low priority of -98. This means, that all usual localboot products will be installed first. -
opsi-auto-update
In essence, this product can be used to ensure that the installed products are up to date.
The product sets all installed products, whose version is not identical to that on the server, for the client to setup.
Since this product can not only be used in the context of opsi-local-image, it is described in the chapter opsi standard products / opsi-auto-update:
Section 8.1.1.19, “opsi-auto-update”
9.8.7. Extended opsi service methods
With this extension, the computers in a training room can be combined in an opsi-client group. In order to provide the most convenient management for all computers in a training room, the following extensions to the opsi-service methods have been implemented:
-
setProductActionRequestForHostGroup
Parameter:hostGroupId, productId, actionRequest
Makes it possible to start a specific action (e.g. restore an image) for all members of a group (e.g. computers in a training room). -
setProductPropertyForHostGroup
Parameter:productId propertyId propertyValue hostGroupId
Makes it possible to set a given product property (e.g. which image is to be restored) for all members of a group (e.g. computers in a training room). -
getPossibleImagefileValuesForHostGroup
Parameter:groupId
Returns the list of image filenames whichopsi-local-image-backuphas created on all members of the group. If a certain image (e.g.opsi-local-image-winxp) is not available on one or more computers, it is not an element of the returned list.
These methods will be integrated into the standard opsi packages at a later date. Until then, a file 40_groupActions.conf is available, which must be copied with root rights to /etc/opsi/backendManager/extend.d. Then execute the following:
opsi-setup --set-rights /etc/opsi.
9.8.8. Backup partition
The backup partition is (with MBR BIOS and without data partition) the third partition of the system hard disk.
On systems with more than one disk, the system hard disk is determined by the opsi-local-image-prepare property multi_disk_mode.
On systems with more than one disk, the backup partition can also be the first partition of another disk, depending on the opsi-local-image-prepare property backup_partition_on_same_disk.
It contains:
-
The file
master.logwith information about all performed image operations. This log file is transferred to the bootimage logs. -
The image directories
The image directories have the same name as the image and contain the image as well as the metadata of the image.
To give an idea about file sizes, here are the sizes of different image directories with OS and standard software (libreoffice, adobereader, firefox, thunderbird, javavm, flashplayer): -
opsi-local-image-ubuntu: 3.6G -
opsi-local-image-winxp: 6.4G -
opsi-local-image-win7: 9.4G -
opsi-local-image-win7-x64: 13G
9.8.9. Capture Images (WIM) generating and distribution
Capture Images (WIM) Introduction
Starting with NT6 (i.e. from Vista) Microsoft has introduced a new image format, the Windows Imaging Format (WIM). A WIM image is no longer a disk or partition image, but rather a file and metadata archive. A WIM file can contain multiple images. The standard installation of a NT6 computer is based on the setup.exe extracting an image from the install.wim file and then configuring it and providing it with additional drivers.
The installed Windows OS including installed software, hotfixes and configurations can be read from an existing computer and saved in the form of a WIM. Such a WIM can then be the basis for new installations.
Capture Images (WIM) Components
To create a capture image in Wim format, from version 4.1 you only need the product:
-
opsi-local-image-wim-capture
The previous products:
-
opsi-local-image-capture -
opsi-local-image-sysprep
are obsolete and can be removed.
In addition, there are the target products which are intended to hold the captured images:
-
opsi-local-image-win7-capture -
opsi-local-image-win7-x64-capture -
opsi-local-image-win81-capture -
opsi-local-image-win81-x64-capture -
opsi-local-image-win10-capture -
opsi-local-image-win10-x64-capture
Capture Images (WIM) Processing
The process and settings for the product opsi-local-image-wim-capture are very similar to the product opsi-wim-capture which is described here: Section 9.4, “opsi WIM Capture”. The properties of opsi-wim-capture are described here: Section 9.4.6.1, “Main Product opsi-wim-capture”.
The main difference between the two products is:
To backup and restore the partition to be captured opsi-local-image-wim-capture uses the mechanism of opsi-local-image-backup/opsi-local-image-restore.
For the same purpose opsi-wim-capture uses the product opsi-clonezilla.
opsi-local-image-wim-capture will fail if you have setup your system with a data partition. In this case, reinstall the computer with the opsi-local-image-prepare property data_partition_size=0.
|
9.8.10. Windows installation from a target product
(Roll out the captured image)
Restore opsi metadata about installed products
The Problem:
If you reinstall Windows with opsi, e.g. win7-x64, then during the installation of the opsi-client-agent all local boot products that were previously set to installed on this computer are automatically set to setup and thus reinstalled later.
This cannot be done in the same way when rolling out a captured image.
The image contains the backup of the opsi data that was stored there during the capture process. This is discovered during the installation of the opsi-client-agent and imported back into the opsi-server. The products that were installed in the captured image are now set to installed for the freshly installed computer.
If all products set to installed were now set to setup, this would result in all products already installed in the image being installed again. This is not desirable.
As of opsi 4.0.7, there are two options for restoring the opsi metadata for installed products:
Option 1
Restore metadata and retain setup action requests.
Products that have the status installed will not be set to setup.
This is the default and the behavior before opsi 4.0.7
Option 2
Restore metadata. Products that are marked as installed are set to setup except those which were contained in the restored metadata.
Option 1
When rolling out a captured image, only those products are automatically installed that were set to setup before the start of the operating system installation. This can be changed manually or with the property setup_after_install.
In this case, therefore, only those products are installed that were set to setup before the operating system was installed.
This is the default and the behavior before opsi 4.0.7
Option 2
Option 2 behaves similarly to installations from non-captured images:
* Restore the metadata.
* Products that are marked installed are set to setup except those which were contained in the restored metadata.
This behavior is only available from opsi 4.0.7 and is not the default. Option 2 has been made possible by extensions to the opsi-script and is part of the opsi-client-agent from 4.0.7.
To use this behavior a config (host parameter) must be set:
The Boolean configuration entry: clientconfig.capture.switch_installed_products_to_setup. If this entry has the value true for the client then option 2 is used, otherwise option 1.
These host parameter can then be used to activate or deactivate client-specific events. The host parameter can be created using opsi-configed or opsi-admin.
To create the host parameter using opsi-admin, the following commands must be executed on the opsi-config-server:
opsi-admin -d method config_createBool clientconfig.capture.switch_installed_products_to_setup "capture.switch_installed_products_to_setup" trueThis sets Option 2 for all computers.
To create the host parameter using opsi-configed, select Server configuration / clientconfig / Right-click on the right side: Add Boolean configuration entry.
9.8.11. Helper product opsi-wim-info
The product opsi-wim-info can be used to quickly read information about the images saved in an install.wim. This information is then saved in the log file.
Properties:
-
target_product
ProductId of the product where is searched for install.wim.

9.9. opsi vhd reset
9.9.1. Requirements for the opsi extension opsi vhd reset
This module is currently a
cofunding project.
It is bundled with the extension opsi-local-image (see Section 9.8, “opsi local image”) - that means: the activation for opsi-local-image also applies to opsi-vhd-reset.
Some conditions have to be met to use this module. This means that you need an activation file to use it. You will receive this activation if you buy the extension. For evaluation purposes, we also provide a time-limited activation free of charge (→ mail to info@uib.de).
Further details can be found in Section 9.1, “Activation of non-free modules”.
As a technical requirement opsi >= 4.0.7 is required with the package versions:
| opsi package | version |
|---|---|
opsi-winst |
>= 4.12.0.13 |
9.9.2. Introduction
To use computers in training rooms within a short time, e.g. to put them back into a defined state during a break between two courses requires special techniques. With opsi-local-image opsi already offers a solution, that is now supplemented by a new method that has specific advantages and disadvantages.
-
Initial Windows 10 installation in a VHD container.
-
Sealing the initial installation by using a child VHD.
-
Quick restore by replacing the child VHD.
-
Upgrade of the initial installation by a merge of the child VHD.
-
This method works with snapshot techniques known from virtualization without using virtualization itself.
9.9.3. Process steps
Initial Installation
Windows 10 is installed in a VHD container using the product opsi-vhd-win10-x64.
The desired applications can then be installed on this Windows.
By executing the opsi product opsi-vhd-control, the current opsi metadata for this client (which product is installed in which version) is stored in the initial installation.
The Windows PE is then activated and booted for the further process.
The product opsi-vhd-control has a very low priority (-97) and therefore only runs after the installation of application software. As a result, the opsi-vhd-control product can be set to setup together with the application software.
After the Windows-PE boots, the second part of opsi-vhd-control starts to work and creates a child VHD which seals the initial installation and records all further changes.
All changes from now are stored in the child VHD.
Fast recovery
The initial installation can be restored using the opsi product opsi-vhd-control.
First, the saved opsi metadata is restored from the system.
Then for handling of the Child VHD the system boots into Windows PE again.
The child VHD with the changes is deleted in Windows PE and replaced with a new, empty child VHD.
Updating an image using opsi-auto-update
To update the initial installation with patches and software updates, you can proceed as follows:
-
Restore the initial installation (as described above)
-
Install the updates
-
Integration of the updates in the initial installation and re-sealing by starting opsi-vhd-control with the property upgrade=true
-
This also stores the new opsi metadata in the system
These processes are carried out automatically by the product opsi-auto-update.
The product opsi-auto-update replaces the previous product opsi-vhd-auto-upgrade
9.9.4. The opsi-vhd products
The extension opsi-vhd-reset consists of the following products:
The netboot product for the initial installation:
-
opsi-vhd-win10-x64
The localboot product to control the creation, the replacement and merge of the child VHDs:
-
opsi-vhd-control
The localboot product to control the fully automatic upgrade of the parent VHD.
-
opsi-auto-update
UEFI Compatibility
The opsi-vhd products are UEFI compatible.
The opsi netboot product opsi-vhd-win10-x64 and its properties
This netboot product is very similar to the normal netboot products (4.1.0) for Windows installations and must be filled accordingly as described in the getting-started manual.
Also the properties are mostly the same.
The following properties are special for this product:
-
windows_vhd_size
This property specifies the size of the base VHD absolute or as a percentage of the harddisk size, minus the WinPE partition. The default value of 100% is automatically reduced to 80% to leave room for the child VHD. If (absolute or relative) a value is entered that would exceed 80%, this is also reduced to 80%.
This property replaces the standard property windows_partition_size
(Default = 100%) -
installto:
This value is vhd and should not be changed.
The following properties are not existing for this product:
-
windows_partition_size,windows_partition_label
See above. The label of the partition on which the VHDs are located is CONTAINER. -
data_partition_size,data_partition_letter,data_partition_create,data_partition_preserve
Currently the usage of a data partition is not possible with opsi-vhd. -
boot_partition_size,boot_partition_letter,boot_partition_label
Currently the usage of a boot partition is not possible with opsi-vhd. -
pre_format_system_partitions,preserve_winpe_partition
With opsi-vhd these two values are always true.
The opsi localboot product opsi-vhd-control and its properties
The opsi-vhd-control product has a very low priority (-96).
-
disabled
This property is for debugging purposes.
If true, the product does not execute any actions.
Default = false -
upgrade
If true: Merge the changes that are collected in the child VHD to the parent VHD. Then replace the child VHD with an empty one.
If false: replace the child VHD with an empty child VHD.
At the end of a successful upgrade run, this property is automatically reset to false.
Default = false -
stop_on_no_network_in_pe
This property is for debugging purposes.
If true: Abort with an error message, to analyze why no network connection could be established. Default = false
The opsi localboot product opsi-auto-update and its properties
opsi-auto-update is a product to simplify the maintenance of the clients.
In essence, this product can be used to ensure that the installed products are up to date.
The product sets all installed products,
whose version is not identical to that on the server,
for the client to setup.
Since this product can not only be used in the context of opsi-vhd-reset, it is described in the chapter opsi standard products / opsi-auto-update:
Section 8.1.1.19, “opsi-auto-update”
Known Problems and Restrictions
-
There is also a 32 bit version. Due to a problem with the diskpart merge command, this can only be used to a limited extent in the 32 bit Windows PE versions.
-
In theory, an implementation for Windows 8.1 or Windows 7 Enterprise would be possible. We will only build these products at request.
-
There are indications that a Windows 10 release upgrade of an installation in a VHD will fail.

9.10. opsi License Management
9.10.1. Conditions for using the opsi License Management extension
This module currently is a co-funded extension and therefore not free. For more details see Section 9.1, “Activation of non-free modules”.
9.10.2. Overview
Main features
The opsi license management module is designed for managing the software licenses for proprietary software installed on opsi clients.
The main features are:
-
Providing license management functions from within the opsi-configed management interface.
-
Easy generation of reports about installed license-bound software, for non-opsi-managed software, based on the software inventory
-
Reconciliation of software installations and license contracts
-
Optionally automated supplying, assigning, and reserving licenses and license keys.
-
The following license models can be used:
-
standard single license - one installation, possibly identified by a license key, on one computer
-
volume (or campus) license - a certain or unlimited number of installations for which one license key is provided
-
computer bound license - a single license for use on a fixed hardware
-
concurrent license - the installations are not limited, the real usage is managed by a license server
-
-
When uninstalling an opsi managed software the assignment of a license (key) is released as well.
-
In addition, license assignments can be edited manually or even by a script, for example, if licenses for software that is not opsi-managed should be integrated.
Overview database model
In the world of non-free software, license management is a complex subject. To represent it, opsi has to implement a relatively complex database model.
The involved tables in the opsi database are sketched in the following diagram. The meaning of the different relations should peu à peu become clear by the following explanations of the opsi LICENSE management concepts and usages.
The blue line in the diagram marks the border of the tables which are automatically generated by the software audit functions and the data which is constructed especially for license management. Only the license pool table has connections to both spheres. This fact hints at the importance of this construct.
Invoking the license management from the opsi-configed
A separate window in the opsi-configed management GUI is used for the license management. It is available by pressing the button "licenses" at the top right corner of the opsi-configed management GUI. If the license management module is disabled, then a note will be displayed. (See the entry for "license management" in the main menu under /Help/Modules).
The opsi license management module is an opsi extension module.
9.10.3. license-pools
The license management frame is constructed similarly to the mainframe, showing a line of tabs that lead to subframes, each subframe handling a specific task.
The first subframe introduces the topic "license pools", and defines their relationship to the data on installed software and opsi packages.
What is a license-pool?
A license-pool has to be defined if licensing is needed to be managed for some kind of software.
The license-pool is a construction that denotes the collection of all allowances for installing some kind of software.
The license-pool is the central element of the opsi license management since it encloses two sides, on one hand, references to installed software items and opsi installation packages, on the other hand, references to the legal and technical constructions of the installation permissions.
Administration of license-pools
At the top of the license-pools window is a table of available license-pools.
The field description can be edited here. More editing functions are available from the context menu (right mouse button). The most important is: creating a New license-pool by adding a new row to the table.
When inserting a row, a (unique) licensePoolId must be entered, e.g. following the scheme softprod_pool.
Please do not use special characters. When saving the new entry, any capital letter will be converted to lower case, therefore avoiding capitals from the beginning is recommended.
The new licensePoolId cannot be changed after it is saved because it is used as the primary key.
After any changes to the data in the window, the green checkmark changes to red, and the cancel option is enabled. The changes can be saved by clicking the red checkmark, or changes can be canceled by clicking the cancel button (also available from the context menu).
license-pools and opsi-products
The standard method to manage licenses is to include the license, from a single license-pool, when installing the software (i.e. using the opsi-product installation software to install Acrobat Writer).
Not unusual is the case that multiple products share the same license pool. This is normal if these products are variants of the same software. For example: the products win10-x64 and opsi-local-image-win10-x64 using the license pool p_win10-x64).
A more complicated situation (which you should avoid) might occur while installing software that requires licenses from several license-pools (i.e. "Designer tools" which installs Adobe Photoshop as well as Acrobat Writer). In this case, the opsi-product requests licenses from several license-pools. At the same time, there might be other opsi-products requesting licenses from the same license-pools (e.g. the Acrobat Writer license-pool). So the relation between opsi-products and license-pools can be ambiguous. This can be avoided by using unambiguous policies when building opsi-products.
| Do not integrate more than one license needing software in one opsi product. Assign this product to the license pool which holds the licenses for this product. (Without this assignment the license management will not work together with the opsi WAN extension. See also chapter Section 9.11, “opsi WAN/VPN extension” ) |
The second part of the license-pool tab manages the relationship between license-pools and productIds (from opsi-products).
All tables in the license management module can have their columns sorted by clicking on the column header. Clicking again inverts the order (ascending or descending).
Sorting can be used to display the connections between opsi-products and license-pools. Sorting by opsi-product displays all license-pools connected to a certain opsi-product, whereas sorting by license-pool shows which opsi-products are connected to a license-pool.
The context menu provides an option for inserting a new relationship between opsi-product and license-pool. An empty row is inserted on top of the table. Clicking into the field licensePoolId or productId displays a dropdown with the available options.
license-pools and installed software
The third section of the license-pools tab deals with the correlation between license-pools and installed software found on computers in the opsi network, either installed via opsi or otherwise.
By default, the table in this section contains the identifying attributes of all captured software items. The ID, which is constructed from combining all attributes, acts as a unique key for every software item installed on any computer. The values are determined and transferred to the server via opsi software audit. They are saved in the SOFTWARE_CONFIG table of the opsi database and added to the collective SOFTWARE table, provided they are not yet present. This database table is the base for the table shown in the license management and is of importance outside of the license management as well.
The display of the software table is configured by two lists of options. The first one enables the possibility to restrict the display on certain data:
-
Show all software names
-
Show software names without uniform assignments
-
Show software names without any assignments
The other defines what the selection of a row entails:
-
Selection = Complete list of SW items assigned/to assign
-
Selection = SW items to assign (additionally)
The first option in both lists is always set by default.
The software items (from the SOFTWARE database table ) that are assigned to the selected license-pool (from the LICENSE_POOL table) are shown by highlighting the respective rows in the tables. This allocation is precisely the data from the AUDIT_SOFTWARE_TO_LICENSE_POOL table.
The assignment of software items to the license-pool can be edited by changing the highlighted rows:
| The assignment of software items to license-pools is edited by changing the various selections, either with Ctrl + click or Shift + click. A single mouse click resets the selection. |
If there is an entry for an allocation of a software item to a license-pool in the database but the software does not seem to exist anymore, then the Missing button is set to active. By clicking the button a new window opens and lists the referred software that seems to be missing. It offers the possibility to tidy up and delete the allocation (from the AUDIT_SOFTWARE_TO_LICENSE_POOL table).
Navigating the Software Table
The navigation of the software table deviates from the usual since selecting an item in the software table entails a change in item allocation. Therefore the location of the cursor in the table is not illustrated by a highlighted row but as a red star at the beginning of the row.
The star, meaning the row cursor, changes position by
-
an implicit search of a table entry (e.g. automatically when showing the assigned software items when the license-pool entry in the license-pools table above is changed),
-
a manual search using the search bar,
-
using the red arrow buttons located directly above the table,
-
clicking directly into the assigned column for the star (the very first column) of the desired row (while clicking any other column of that row resets the entire selection).
The allocation of software items to license-pools as a basis for a compliance check
The main principle is simple: When a software pool is established, the utilized software items for this pool are selected with a few mouse clicks. This forms the data basis (for example for the compliance check from Microsoft) to determine the number of installations linked to a pool. The result of this evaluation can be found in the Statistics tab (Section 9.10.8, “License usages overview”).
The allocation of software items to license-pools has to be maintained meticulously to receive correct results. Especially when software from a license-pool is installed, the specific software item has to be registered to the respective pool.
The different possible configurations of the displays are used to provide functions to support various policies and best practice in data maintenance.
Function: Filtering the assigned software items
The context menu of the table provides the option to switch between viewing all entries (including the highlighted rows) or exclusively the marked ones. Thereby one obtains a list of all assigned software items in the default configuration. This can be helpful since the rows of assigned software items do not necessarily follow each other directly in the overall software list.
After switching to viewing only the marked items:
Instead of using the context menu, one can also click on the filter icon next to the search bar which gives the same result. When all rows are shown this icon appears as an open filter, and when only the highlighted rows are shown the icon appears as a closed filter.
In the filtered view the allocations can be edited as well. In this case, allocated items can only be removed.
Function: Completing the allocations to a software name
When a manufacturer of a software releases a new version or patch, the new version receives a new windowsSoftwareId and therefore shows up as a new entry in the software table (with a new ID). In most cases, the new software can be treated the same way for licensing as the previous version. If a license agreement was required for the old version, the same likely holds for the new one. This means the demand for a license has to be registered via the same license-pool for both versions. Covering the demand can then be organized via the shared license-pool.
It is important to make sure when rolling out a new version that an allocation is added to the respective license-pool. Besides, some software updates itself without active involvement. Then after the update, the correct allocation might be missing maybe even unnoticed. That is why (since version 4.1.9.8) the opsi-configed includes an auxiliary function to simplify the completion of allocations.
As a basis for this we assume that the data field name is often sufficient to identify the license-pool, and differences in components of the software ID can (often) be ignored in this regard. The functions and options in the gray box with the label Alternative view serve for working with this hypothesis. The button Name → Pool opens an additional window.
The additional window contains two auxiliary tables. When prior to calling the window the default setting was left at Show all software names, the first column of the first table now displays the software names in alphabetical order. The second column lists all IDs that are associated with the respective name (although the first part of the ID, being the exact software name, is not repeated for simplicity reasons).
When selecting a name in the first table, the dependent second table displays the corresponding IDs individually and specifies if an allocation to a pool exists, and if so to which pool. The license-pool allocations can be unified across all rows of the table in three ways:
-
Remove all allocations,
-
Allocate the currently (in the main window of the license management) selected pool to all ID variations (this is presumably the standard case),
-
When the different variations are currently assigned to different pools, assign all of them to the pool belonging to the selected row.
Since one would like to systematically check the license-pool allocations, it is recommended to click the option to show software names without uniform assignments prior to calling the window. When this option is set, the upper table is reduced to the software names that correspond to multiple IDs where those IDs are also assigned to different license-pools.
If such allocation differences exist, an "i" in a small Box within the gray Box of the license management appears as an indicator. This information is designed discreetly, since, depending on the licensing case, it can be correct or even needed to have different software variations licensed differently.
To search for possible forgotten license allocations, the additional window can be opened with the third and final option show software names without any assignment.
Function: Recognizing non allocated Software
Instead of relying on the previously depicted process, thorough license management can also be achieved by assigning every registered software to a license-pool.
For this to work in practice, pseudo license-pools like "free Software" or "Operating System components" are needed to which software items that do not have or require any separate licensing can be assigned to.
To simplify the implementation of this strategy, the opsi-configed offers this additional display option (cf. Figure 107, “Software table configuration”):
Assuming the initial situation is that the previously registered software has universally been assigned to license-pools, then the following sequence of steps are expedient:
-
Installing a (new) software on a computer.
-
Running swaudit on the computer.
-
If the software is indeed new, the software table receives a new entry; there can also be multiple entries (for example when libraries are installed).
-
When preselecting a suitable license-pool and activating the option Show software names without uniform assignments, then the new table entries are the only highlighted ones.
-
If the preselected license-pool is suitable, a new entry for this license-pool can be added to the previously registered with "Ctrl + click".
For the distribution of arbitrary, initially not determined software items to license-pools, the following procedure can be used:
-
Activate the option Show software names without any assignments
-
Change to edit mode Selection = SW items to assign (additionally)
-
Select and highlight rows using "Ctrl + click"

9.10.4. Setting up licenses
Setting up a license or supplying a license to a license-pool requires several steps. These can be performed in the New license tab, the second tab in the license management window.
At the top there is a table of available license-pools to select the license-pool that the new license is to be assigned to.
Before continuing with the next steps, some basic concepts and terms of license management have to be introduced:
Some aspects and terms of the license concept
Licensing means the actual deployment of a permission to use software by installing the software on a client. This might (but does not have to) include the use of a special license key (license key).
The software license is the permission to install and use a software as defined by the license contract. Within the opsi database, a software license is identified by a softwareLicenseId.
There are several types of software licenses (volume license, OEM license, time-limited license, etc.) which are the different license models. A software license is based on a license contract, which defines and documents the juristic aspects of the license.
A license option defines the option to use a software license for a selected license-pool. Within opsi, the license option is defined by a combination of softwareLicenseId and licensePoolId. This includes the actual licenseKey (if required).
Finally, the license usage documents the use of a license by assigning the license option to a client. This is the legal and implemented licensing of software, defined by the combination of softwareLicenseId, licensePoolId, the unique client name hostId, and (if required) the licenseKey.
Registering the license contract
The next step after selecting the license-pool for the new license option is to register the license contract that the license should be based on. Under "Select or enter license contract" (in the "New license" tab) an existing contract can be selected or a new one can be created.
The license contract dataset comes with the data fields partner, conclusion date, notification date, and expiration date. The entry field notes can hold some additional information like the location where the contract document is kept. The unique contract ID (licenseContractId) is for identifying the license contract in the license management database. When entering a new license contract, a new unique ID is automatically constructed based on the current date and time stamp. The default setting can be used if the license contract is implied by purchasing the software or the contract is documented and traceable some other way. Otherwise, the data can and should be edited to ensure orderly tracking of the underlying contract which can be for example through reference to a file number in the notes field.
The contract ID can only be changed before saving the new data set. When saving the data, the opsi service checks whether the ID is unique. In case it is not, a new ID is generated and cannot be changed anymore.
Configuring the license model
The third part of the "New license" tab, "Configure license", is for registering the license model and license data.
Several types of license models are available:
-
Standard license
-
Volume license
-
OEM license
-
Concurrent license
Each option is represented by a button. By clicking one of the buttons the form is filled with data for that type of license model.
The license model Standard license means, that this license is valid for a single installation on an arbitrary client. So the license key (if any) is valid for a single installation only.
A Volume license is valid for a certain number n of installations. In this case, the optional license key is used for that number of installations. Setting n = 0 means, that the number of installations is unlimited within the same network (campus license).
In the case of an OEM license, the license is valid for a dedicated client only. Clients that come with a vendor pre-installed operating system often have this type of license for the pre-installed OS and software packages.
The Concurrent license means that a certain number of licenses is available for a variable set of clients. Within opsi, this situation is handled like an unlimited Volume license. The number of actual installations in use has to be managed by some external license server.
After clicking a button, the automatically generated data include a unique generated ID (derived from date and time stamp). This ID can be changed as desired.
It depends on the type of license model, which of the other fields can or cannot be changed.
The field "Expiration date" defines the expiration date of the license in a technical sense. (This column of the license is for future use).
Saving the data
The "Send" button sends the data to the opsi service to save them permanently to the opsi database (if they are consistent and no errors occur).
While proceeding with this, data records will be generated for the new software license based on the selected software contract and the new license option assigned to that.
The list of available license options at the bottom of the window will be refreshed with the new license option selected. If necessary, the license key can be changed then.
9.10.5. Editing licenses
In ninety percent of the use cases editing the license data with help of the tabs "License pools" and "New license" will do. But there might be some special cases where more specific and explicit editing of the license data is needed. For this, the "Edit licenses" tab presents the license data in three tables, representing the internal data structure and allowing to adapt the data for some special cases.
Based on this direct data access, the following chapter shows how to configure a special license, like the Microsoft Vista or Windows 7 Professional downgrade option for installing Windows XP.
Example downgrade option
The downgrade option means, that instead of the purchased software, the preceding version can also be installed. For instance, installing Windows XP based on a Windows Vista license. In this case, the license key can also be used for an installation, which it was not meant for originally.
In the opsi license model this case can be configured like this:
From the "New license" tab the Vista license is to be registered, as usual, resulting in a new license option, which is displayed in the list of license options at the bottom of the window. This new license option is based on a new software license identified by softwareLicenseId.
This softwareLicenseId is needed for further configuration steps. You can keep it in mind or copy it with drag&drop. You can look for the ID in the "Available license options" list of the "Edit licenses" tab as well. The context menu also supports copying the ID.
The important step now is to connect this softwareLicenseId to an additional license-pool.
For this, a new record has to be registered from the "Available license options" table of the "Edit licenses" tab. The fields of the new record have to be filled with the softwareLicenseId and the ID of the additional license-pool (in this case the pool for Windows XP licenses). To install Windows XP based on this license, an applicable Windows XP license key that is already in use by another client has to be added.
After saving the new record, there are two different license options based on the same software license! The opsi service counts the use of both of them as an installation deducting from the maximum installation count. So in case of a downgrade license (with maxInstallations = 1), the opsi service delivers a license key for a Vista installation or for an XP installation, but not for both of them.
9.10.6. Assignment and release of licenses
Using a license option by installing the software on a client results in the actual licensing.
In the opsi context, installations are done script-based and automatically. The client running the Winst script then invokes calls to the central opsi service.
The following chapters introduce some of these service calls, which are relevant for license management. For further information about Winst and opsi commands see the documentation on Winst and opsi.
opsi service calls for requesting and releasing a license
The opsi service call for requesting a license option and retrieving the license key for doing the installation (as transmitted by a Winst script) is
getAndAssignSoftwareLicenseKey.
The parameters to be passed are the client hostId (hostID of the client where the software is to be installed) and the ID of the license-pool that the license is requested from. Instead of the licensePoolId, an opsi-product ID or a Windows Software ID can also be passed if they are connected to a license-pool within the opsi license management.
The use of a license option can be released by calling deleteSoftwareLicenseUsage.
Again the parameters to be passed are the hostId and alternatively the licensePoolId, productId or Windows Software ID. Calling this method releases the license option and returns it to the pool of available license options.
For the complete documentation of opsi service calls see below.
opsi-winst script calls for requesting and releasing of licenses
The opsi-winst provides the client-related calls as opsi-winst commands.
An opsi-winst script can make a call to the function DemandLicenseKey
to get a license key for installing. The parameters to be passed are:
DemandLicenseKey (poolId [, productId [, windowsSoftwareId]])
The return value is the license key (which can be empty) as a string:
set $mykey$ = DemandLicenseKey ("pool_office2007")The returned license key can be used by other script commands for installing the software.
For releasing a license option and license key (as to be used in an opsi-winst
deinstallation script) the command FreeLicense is available with the following syntax:
FreeLicense (poolId [, productId [, windowsSoftwareId]])
The boolean function opsiLicenseManagementEnabled can be used to check
whether the opsi license management is enabled and can be used for scripting:
if opsiLicenseManagementEnabled
set $mykey$ = DemandLicenseKey ("pool_office2007")
else
set $mykey$ = IniVar("productkey")The service calls can be invoked from the command-line tool opsi-admin.
Parameters marked with * are optional.
License contracts
method createLicenseContract(*licenseContractId, *partner, *conclusionDate, *notificationDate, *expirationDate, *notes)This method registers a new license contract record with the ID licenseContractId. If no licenseContractId is passed, it will be generated automatically. Using the licenseContractId of an existing contract, this contract can be edited.
The parameters partner (co-contractor) and notes are strings and can be filled with any information desired.
The parameters conclusionDate (date of conclusion of the contract), notificationDate (date for a reminder) and expirationDate (expiration date of the contract) are passed in the format YYYY-MM-DD (e.g. 2009-05-18).
The method returns the licenseContractId of the contract.
set $mykey$ = DemandLicenseKey ("pool_office2007")
else
set $mykey$ = IniVar("productkey")With the string returning functions getLastServiceErrorClass and getLastServiceErrorMessage error states can be detected and handled, e.g. if there is no license available:
if getLastServiceErrorClass = "None"
comment "no error"
endifThe error class LicenseMissingError is returned if a license has been demanded but there is no license available.
The error class LicenseConfigurationError is returned if the current configuration does not allow assignment of a license pool to a software.
This could be the case if either no assignment exists or no distinct assignment is possible.
Manual administration of license usage
Within the opsi config editor, the licenses registered by the opsi service are listed on the tab "License usages":
From this tab, licenses can also be managed manually. This can be useful, if a licensed software is not integrated into the opsi deployment, but installed manually on just a few clients.
These are the functions for manual license management in detail:
-
"Delete row" (available from the context menu) releases a license option.
-
"Reserve license for client" at the bottom of the window to create a license reservation for a dedicated client.
-
By editing the field "licenseKey" from the "Usage of licenses" table, the license key can be changed.
Preservation and deletion of license usages
If a software packet is reinstalled, the call to the opsi-winst function DemandLicenseKey will return the same license option and license key as used before.
In case this is not favored, the former license option has to be released by calling the opsi-winst command FreeLicense, or by calling the opsi service call deleteSoftwareLicenseUsage, or deleting the license use manually.
So, if not explicitly deleted, the license usages are preserved when reinstalling a client.
To release the licenses, they can be deleted from the "License usage" tab or deleted by the service call deleteAllSoftwareLicenseUsages by passing the client host name as a parameter.
9.10.7. Reconciliation with the software inventory
The tab "Reconciliation" lists for each client and each license-pool whether the use of this license-pool is registered by opsi ("used_by_opsi") and if the software inventory (swaudit) on that client reported a software that requires a license option from that pool (Swinventory_used).
To evaluate the results from swaudit, the relevant software IDs (as found in the client registry) have to be associated with the appropriate license-pool (tab "License pools").
When matching the data with the software inventory, the license management counts not more than one license per client and license-pool. So for example if the license-pool office2010 is connected with ten different patterns from software inventory, indicating that office2010 is installed on this client, this is (regarding the license usages count) counted as a single installation, although all of the detection patterns might be found on the client.
As usual, this table can be copied using Drag & Drop and for instance pasted to a spreadsheet program. If the opsi-configed process has the required access rights (running standalone and not from the applet), the table can also be printed from the context menu.
By virtue of the config configed.license_inventory_extradisplayfields which can be edited in the host parameter page of the server, you may add extra data fields for each client to the table.
9.10.8. License usages overview
The tab "Statistics" displays a summary of the different license-pools, showing the total number of license options (license_options) and how many of them are in use (used_by_opsi) or still available (remaining opsi).
In addition to the number of license-uses registered by opsi (used by opsi) and the currently available licenses (remaining…), the overview also shows the total number of detected installations, that require a license (SWinventory_used).
The data from the column SWinventory_used is based on the registry scans from the opsi-product swaudit and the assignment of the Windows software IDs (as they are found in the registry) to the license-pools (as registered with the opsi license management (tab "License pools", see Section 9.10.3, “license-pools”).
From the context menu, the table can be printed (because of restricted access rights not available from the applet), and using drag&drop data can be copied to e.g. a spreadsheet.
In case of downgrade option
If a downgrade option has been configured (see Section 9.10.5.1, “Example downgrade option”), it appears in the overview and statistics like this:
A single downgrade license results in a license option for at least two different license-pools but only one of them can be requested for an installation. So using a downgrade license option decreases the number of available license options (remaining_opsi) in each of the license-pools concerned by that downgrade option by 1. So it looks like a single installation reduces the number of available license options by 2, which, in this case, actually is the fact.
9.10.9. Service methods for license management
The service methods for license management can be called from the command-line tool opsi-admin, so they are accessible for scripting, e.g. to read license keys from a file.
Examples can be found in the products license-test-….opsi from https://download.uib.de/opsi4.1/misc/license-management/. After installing the packages with opsi-package-manager -i *.opsi, in the directory /var/lib/opsi/depot/<product name> the corresponding scripts: create_license-*.sh can be found.
As an example here the script create_license-mixed.sh
(the current version comes with the download packet).
#!/bin/bash
# This is a test and example script
# (c) uib gmbh licensed under GPL
PRODUCT_ID=license-test-mixed
# read the license key from a file
# myretailkeys.txt has one licensekey per line

In the uib download section at https://download.uib.de/opsi4.1/misc/license-management/ are four example products available. One for each type of license model, as there are Retail, OEM and Volume license type, as well as a product combining all of them.
These example products use as an example some licenses and release them again. So using them leaves some marks in the software inventory, that might be of influence to reconciliation and statistics.
All of these products contain a shell script to automatically generate license-pools, license contracts and license options.
The standard template for opsi-winst scripts opsi-template also contains some examples for using the opsi license management.
9.11. opsi WAN/VPN extension
The WAN/VPN extension module allows to integrate clients, that are connected via low speed connections. This chapter is about configuring and maintaining the opsi WAN/VPN extension.
9.11.1. Preconditions for using the WAN/VPN extension
This opsi extension is currently in the cofunding process and not free. For more details see Section 9.1, “Activation of non-free modules”.
There are some preconditions to use the WAN/VPN extension module. The feature product groups is required, which is available with opsi 4.0 and above. Also the packets opsi-client-agent and opsi-configed are required, which come with version 4.0.1.
At the moment, the simultaneous use of both "WAN extension" and "installation on shutdown extension" is not supportet. On the same opsi server with different clients, these opsi extensions can be used.
| opsi-Packet | version |
|---|---|
opsi-client-agent |
>=4.0.1-1 |
opsi-winst |
>=4.10.8.12 |
python-opsi |
>=4.0.1-7 |
opsi-configed |
>=4.0.1.6-1 |
9.11.2. General overview of the WAN/VPN extension
opsi software deployment is mainly doing the following steps:
-
The opsi-login-blocker at client system startup prevents the users from logging on.
-
The opsiclientd service running on the client connects the opsi-config-server.
-
If any product actions are set for the client, it mounts a share from the opsi-depot.
-
The opsi-winst is starting and also connects to the opsi-config-server.
-
The opsi-winst executes the product actions, using the share from the opsi-depot.
-
If a reboot is required, it executes and the process starts all over.
-
When all the product actions are completed, the log files are transferred to the opsi-config-server and the user logon is unblocked.
Now we will look at the special circumstances of a client, which is located in a remote branch, connected via WAN to the LAN, where the opsi-config-server and opsi-depot-server are:
-
During communication with the opsi-config-server small amounts of data are transferred, so there is no noticeable slowdown of the software deployment in a WAN.
-
But processing the product actions might consume a very long time, depending on the packet sizes, bandwidth and latency of the WAN connection. There also might occur timeouts during file access.
-
Therefore, during the installation is processing, the user has to wait for an unreasonably long time before logon is granted.
As an alternative to providing a dedicated opsi-depot-server in the remote branch network, the remote clients can be connected via WAN/VPN extension module. Using the WAN/VPN extension module, the opsi-client-agent can be configured this way:
-
At system startup, if there are no opsi-products cached and ready for installation, the user can logon immediately.
-
When there are product actions set for the client, the opsiclientd, which is running on the client, starts downloading the required installation files from the opsi-depot to the local file system. This is done in the background while the user is working. The maximum download bandwidth can be configured and also can be dynamically adapted to the current network traffic status.
-
When the synchronization of the opsi-products is completed, a reboot request is triggered.
-
The logged on user can accept the reboot request, or the client will be rebooted at some time later on.
-
At the next system startup, the cache is found to be filled with the opsi-products to be installed and the installation starts. In this case, the installation will use the downloaded files from the local file system, which increases the speed of installation even compared to a standard LAN installation.
Now we examine the situation of a notebook, which at system startup often cannot connect the opsi-config-server:
-
Trying to connect the opsi-config-server at system startup will result in a timeout.
-
Connecting the opsi-config-server might be possible when a user logs on and a VPN connection to the corporate network is established.
-
Without connection the opsi-config-server no software deployment is available.
This situation also can be solved by using the WAN/VPN extension module.
The opsi-client-agent can be configured the following way:
-
At system startup, if there are no opsi-products cached and ready for installation, the user can logon immediately.
-
Triggered by network activation or a by timer event, the opsiclientd running on the client tries to connect the opsi-config-server.
-
If the opsi-config-server is reachable, the opsiclientd starts to:
-
synchronize the configurations
-
download the required files from the opsi-depot to the local file system.
In combination with the opsi extension module Dynamic Depot Selection, the download is done from the best fitting opsi-depot.
-
-
When the synchronization of the opsi-products is completed, a reboot request is triggered.
-
The logged on user can accept the reboot request or the client will be rebooted at some time later on.
-
At the next system startup, the cache is found to be filled with the opsi-products to be installed and the installation starts. In this case, the installation will use the downloaded files from the local file system, which increases the speed of installation even compared to a standard LAN installation. So the opsiclientd takes over the function of both the opsi-config-server and the opsi-depot-server.
-
At the next connect to the opsi-config-server the results of the installation process (configuration change, log files …) will be synchronized.
The download mechanism of product synchronization is multiple interruptible and will continue at the point of interruption. So files that are already downloaded will not have to be downloaded again.
The WAN/VPN extension module allows to connect clients, that are outside of the secure corporate network. Therefore additional security mechanisms are required regarding the communication between client and server.
So the opsiclientd now offers the ability to verify the identity of an opsi-server.
Therefore the key pair of the SSL certificate of the opsiconfd is used.
By this mechansim the opsi-config-server as well as the opsi-depot-server can be verified,
assumed the communication is performed via opsiconfd and SSL.
In case of an opsi-depot the file access must be done by the opsiconfd using HTTPS/WEBDAVS.
Access done via CIFS/SMB will not be checked.
9.11.3. Caching of opsi-products
Caching of opsi-products is done by the ProductCacheService, which is part of the opsiclientd.
The ProductCacheService synchronizes the local copy of an opsi-product with the current version of the corresponding opsi-products on the opsi-depot.
The location of the local product cache can be configured and defaults to %SystemDrive%\opsi.org\cache\depot.
Communication Protocol for accessing an opsi-depot
For transferring the product files, two different protocols are used:
-
CIFS/SMB
-
HTTP(S)/WEBDAV(S)
In case of using CIFS/SMB, a connection to the depotRemoteUrl will be established as configured with the properties of the opsi-depot. In case of using HTTP(S)/WEBDAV(S), the depotWebdavUrl is connected, which as well is to be configured with the properties of the opsi-depot.
Which protocol is to be used, can be configured client specific by the host parameter clientconfig.depot.protocol.
Available values to be set as clientconfig.depot.protocol are cifs and webdav.
| Also the opsi-linux-bootimage is evaluating this setting and uses the specified protocol. |
With opsiclientd, a different protocol can be used for individual events via the depot_protocol attribute.
|
Using the .files file for Synchronization
The synchronization process is based on the file <product-id>.files, which is located in the base directory of each opsi-product on the opsi-depot.
This file contains information about the files, directories ans symbolic links used by an opsi-product.
Each line of that file contains such information. Different types of information are separated by a blank.
The first character of a line defines the type of the following entry. Available values are:
-
dfor a directory -
ffor a file -
lfor a symbolic link
Separated by a blank follows the relative path, which is single quoted.
The next entry gives the sizes of the file (which is 0 for directories and symbolic links).
The final entry in case of a file is the MD5-sum of the file, in case of a symbolic link it is the target referred to by the symbolic link.
Example excerpt of a .files file:
d 'utils' 0
f 'utils/patch_config_file.py' 2506 d3007628addf6d9f688eb4c2e219dc18
l 'utils/link_to_patch_config_file.py' 0 '/utils/patch_config_file.py'The .files file is generated automatically when installing opsi-product-packages (after running the postinst-Script).
| When using the WAN/VPN extension, the files of opsi-products on the opsi-depot should not be changed manually, otherwise the information contained in the .files file would be outdated, causing errors during the synchronization process. |
Internal processing of opsi-product caching
The synchronization of a local copy of an opsi-product processes as follows:
-
The .files file of the opsi-product is transferred to the local client.
-
Then it is checked, whether there is enough local disk space available to cache the opsi-products. If there isn’t enough disc space available, some old opsi-products will be deleted, which haven’t been used (synchronized) for a long time.
-
The local caching directory will be created if it doesn’t exist.
-
Referring to the .files file, any old files and directories, which aren’t in use anymore, will be deleted from the local opsi-product cache.
-
Then the .files file will be processed in the following order.
-
missing directories are created.
-
missing files are transferred.
-
existing files will be checked by size and MD5-sum and be synchronized again if necessary.
-
The synchronization results in an exact local copy of the opsi-product from the opsi-depot.
| On windows systems, no symbolic links will be created. Instead of links there will be copies of the link target. |
When the opsi-product has completed successfully,
-
the status of
products_cachedwill turn totrue(and staystruein case of a system restart, see: Section 6.1.3.7, “Configuration of different events”). -
a
sync completedevent will be triggered.
Configuring the opsi-product caching
The opsi-product caching is configured in the section [cache_service] of the opsiclientd.conf.
-
product_cache_max_size(integer): The maximum size of the opsi-product cache in byte. This is important to limit the disk space to be used by opsi-product caching. -
storage_dir(string): the path to the directory, in which the base directorydepotfor the opsi-product caching is to be created.
Further configurations can be done event specific.
Within an event configuration section [event_<event-config-id>] the following options are available:
-
cache_products(boolean): if the value of this option istrue, in case of the event the ProductCacheService will start to cache opsi-products, for which a product action is set. If additionally the value of the optionuse_cached_productsis set totrue, the further processing of this section will be suspended until the caching of opsi-products is completed. -
cache_max_bandwidth(integer): the maximum bandwidth in byte/s to be used for caching. If this value is set to 0 or less, the bandwidth is unlimited. -
cache_dynamic_bandwidth(boolean): if the value of this option is set totrue, the bandwidth will be adapted dynamically. Therefore the network traffic at the network interface to the opsi-depot will be monitored. If any traffic is detected, which is not caused by the opsi-product caching, the bandwidth for the caching will be sharply reduced, to allow other processes to work at (almost) full speed. If the caching works at reduced bandwidth and no more other network activity but the opsi-product caching is detected, the caching process will continue with unlimited bandwidth. The value ofcache_max_bandwidthwill be used to limit the maximum dynamic bandwidth. -
use_cached_products(boolean): if the value of this option is set totrue, the local opsi-product cache will be used for processing product actions. If caching of the opsi-products is not completed, the processing of this event will stop and return an error code.
9.11.4. Caching of configurations
The caching of configurations is done by the ConfigCacheService, which is part of the opsiclientd.
The ConfigCacheService synchronizes a local client-cache-backend with the config backend of the opsi-config-server.
The opsiclientd provides per WebService an access point to the backend and thereby provides quite the same functionality as the opsiconfd.
The local client-cache-backend
The local client-cache-backend is based on SQLite and mainly consists of a local working copy,
a snapshot an a modification tracker, which records all changes of the local working copy.
The base directory of the config cache can be configured and defaults to %SystemDrive%\opsi.org\cache\config.
The snapshot reflects the configuration status on the opsi-config-server at the time of the last synchronization.
At the start of the processing, the local working copy is a copy of the snapshot, but will be modified during processing.
Internal processing of configuration synchronizing
The synchronization of the local changes of the client-cache-backend with the config backend of the opsi-config-server is processed as follows:
-
The changes of the local working copy registered by the modification-tracker are transferred to the opsi-config-server. Any changes of the configuration on the opsi-config-server since the last synchronization will be detected by comparing to the snapshot. If there are any conflicts deteced, the following rules apply:
-
In case of inventory data, the local client data have priority.
-
For action requests the value of the client is valid, unless the version of the corresponding package has changed in the meantime on the server side. Then the server value is preferred.
-
In case of installation status and action result, the client data have priority.
-
If the opsi licenense management modul is switched on (config: license-management.use=true), the config server tries to find a license pool for the product by the assignment pool to productId. I free license of this pool will be reserved and this license will be replicated. Any unused licences, which have been reserved during replication, will be released again.
-
The new state of host parametern and product properties is only transferred to the server if they have not been changed server-side in the meantime.
-
-
The modification tracker will be cleared.
-
The logfiles will be transferred.
The config backend replication of the opsi-config-server to the client-cache-backend is processed as follows:
-
The replication only takes place, if any action requests are set on the opsi-config-server. The product action
alwaysdoes not count in this respect. The replication process will start only if the status of action requests is changed since the last replication. -
The modification tracker and the local working copy are cleared.
-
The configurations required for local processing will be replicated.
-
If action requests are set for opsi-products which are marked as to require a license, the required software license will be reserved from a license pool, which is assigned to that opsi-product.
-
Additionally required data, as there are the
auditHardwareConfigand themodules, will be transferred. -
The snapshot and the local working copy will be updated, so they have the same content.
A successful replication from server to client results in:
-
The status of
config_cachedis set totrue(and staystruein case of a system restart, see: Section 6.1.3.7, “Configuration of different events”). -
An event of type
sync completedwill be triggered.
Configuration of config caching
The configuration of the config caching is mainly done event specific:
Within an event configuration section [event_<event-config-id>], the following options are available:
-
sync_config_to_server(boolean): if the value of this option is set totrue, the ConfigCacheService in case of that event starts to transfer the changes registered by the modification tracker to the opsi-config-server. The process will wait for that task to complete. -
sync_config_from_server(boolean): if this value is set totrue, the ConfigCacheService starts with the replication. If additionally the value of the optionuse_cached_configis set totrue, the processing of this event is suspended until the replication is completed. -
use_cached_config(boolean): if the value of this option is set totrue, the client-cache-backend will be used for processing the product actions. If the synchronization is not completed, the processing of this event will be stopped and return an error code. -
post_sync_config_to_server(boolean): has the same functionality assync_config_to_server, but will be evaluated after the product actions have been completed. -
post_sync_config_from_server(boolean): has the same functionality assync_config_from_server, but will be evaluated after the product actions have been completed.
9.11.5. Recommended configuration when using the WAN/VPN extension module
The opsi-client-agent-package comes with a opsiclientd.conf prepared for the WAN/VPN extension.
For activating the WAN/VPN extension, just enabling of some events and disabling of some others is required.
The configuration of the opsi-client-agent also can be done from the web service (see: Section 6.1.3.13, “Configuration via web service (Host Parameter)”),
so it is recommended to create the following host parameter:
-
opsiclientd.event_gui_startup.active(boolean, default:true) -
opsiclientd.event_gui_startup{user_logged_in}.active(boolean, default:true) -
opsiclientd.event_net_connection.active(boolean, default:false) -
opsiclientd.event_timer.active(boolean, default:false)
By these host parameter, events can be enabled or disabled client specific. The host parameter can be created using the opsi-configed or opsi-admin.
For creating the host parameter by opsi-admin, the following commands have to be executed on the opsi-config-server:
opsi-admin -d method config_createBool opsiclientd.event_gui_startup.active "gui_startup active" true
opsi-admin -d method config_createBool opsiclientd.event_gui_startup{user_logged_in}.active "gui_startup{user_logged_in} active" true
opsi-admin -d method config_createBool opsiclientd.event_net_connection.active "event_net_connection active" false
opsi-admin -d method config_createBool opsiclientd.event_timer.active "event_timer active" falseThe default values are as they come with the special opsiclientd.conf.
| If you do not set the defaults like described above and skip directly to the commands below you set all your clients into WAN mode ! |
For a WAN/VPN client, which shall do caching of configurations and opsi-products, the host parameter have to be configured as follows:
-
opsiclientd.event_gui_startup.active:false -
opsiclientd.event_gui_startup{user_logged_in}.active:false -
opsiclientd.event_net_connection.active:true -
opsiclientd.event_timer.active:true
The client specific host parameter can be set by opsi-configed or opsi-admin.
To set the host parameter by opsi-admin, the following commands have to be executed on the opsi-config-server:
(in this example the client has the opsi-host-Id vpnclient.domain.de):
opsi-admin -d method configState_create opsiclientd.event_gui_startup.active vpnclient.domain.de false
opsi-admin -d method configState_create opsiclientd.event_gui_startup{user_logged_in}.active vpnclient.domain.de false
opsi-admin -d method configState_create opsiclientd.event_net_connection.active vpnclient.domain.de true
opsi-admin -d method configState_create opsiclientd.event_timer.active vpnclient.domain.de trueThis configuration will process as follows:
-
At system start of the client there will be no connection established to the opsi-config-server.
-
When the activation of a network interface is detected, a connection to the opsi-config-server will be established (if possible) and the synchronization starts as background task.
-
A
timer-Event will be established, which tries at regular intervals to trigger the synchonization process.
Setting the protocol for caching of opsi-products
The caching of opsi-products can be done via the protocols HTTPS/WEBDAVS or CIFS/SMB.
When using webdav, access to the opsi-depot is performed by the opsiconfd.
-
advantages:
-
easy firewall configuration, for it requires just port 4447.
-
verify of the SSL-certificate of the opsi-depot available.
-
-
disadvantage:
-
the opsiconfd generates more traffic on the opsi-depot.
-
By using cifs, access to the opsi-depot is done via SAMBA.
-
advantage:
-
the SAMBA-server shows a good performance, is resource-conserving and well scaleable.
-
-
disadvantages:
-
the firewall configuration is more complicated, access to the SAMBA ports is required.
-
no verify of the SSL-certificate of the opsi-depot is available.
-
An instruction for configuring the protocols is to be found in the chapter Section 9.11.3.1, “Communication Protocol for accessing an opsi-depot”.
Verifying the server certificates
To activate the verifying of SSL certificates, in the opsiclientd.conf within the section [global], the option verify_server_cert is to be set to true.
This, during connection to an opsiconfd, results in verifying the opsi-server by using the SSL certificate.
The server certificates will be stored in the directory %SystemDrive%\opsi.org\opsiclientd\server-certs.
The name of the certificate is combined from the server address (IP or name) and the extension .pem.
If at connection time no stored certificate is to be found, no checking will be done.
To publish a changed certificate, the old certificate stored on the clients has to be deleted.
This can be done by the RPC-method deleteServerCerts, which is available from the control interface of the opsiclientd.

9.12. FAQ for setup and application of the WAN extension
9.12.1. Do I need a license?
Yes, the extension is still part of the cofinancing scheme and therefore subject to a fee. Additionally for the operation of the WAN extension the MySQL backend is required which is also not free. You can test the extensions free of charge for a limited ammount of time. In order to do so please contact info@uib.de
9.12.2. How do I activate the WAN extension on a client?
The activation of the WAN extension can be perfomed per client via the checkbox on the management console. The client will receive the specific configuration change the next time it connects to the opsi server. It then becomes active the next time the client is restarted.
9.12.3. Must the opsi client agent be deployed once again for the activation?
No, that is not necessary since the client can get the configuration automatically at the next connection to the opsi server. That can be at the next boot process or after an "on_demand" event.
9.12.4. How can I activate clients that are already in Home Office?
If the clients can be reached by the opsi server in home office, the change of the configuration can be performed by triggering an "on_demand" event. (This only works if the data transfer is set to cifs)
In the event that the clients in the home office cannot be reached by the opsi server, they can be updated via this opsi-admin call. (This should also work for clients that have been switched to webdav)
On the command line of the server this can be done using:
opsi-admin -a https://<ClientIp>:4441/opsiclientd -u <user> -p <pass> method fireEvent "on_demand"
or
opsi-admin -a https://<ClientIp>:4441/opsiclientd -u "<FQDN>" -p "<OpsiHostKey>" method fireEvent "on_demand"Replace the corresponding entries:
-
<ClientIp> = IP address of the clients
-
<user> = local administrator on the client or a member of the local administrator group
-
<pass> = password of the administrator
-
<FQDN> = FQDN of the client
-
<OpsiHostKey> = opsi hostkey of the client
9.12.5. How big is the cache on the client?
The cache on the client is set to 20 GB by default.
