       veyon-cli - Veyon Command Line Interface

SYNOPSIS

       veyon-cli help

       veyon-cli <module> help

       veyon-cli <module> help <command>

       veyon-cli <module> <command> [parameters]

DESCRIPTION

       VEYON-CLI is a command line tool that in addition to the Veyon Configurator allows various
       configuration adjustments, automated tasks and the use of  some  Veyon  functions  without
       graphical  interaction.  The  program  is  run either interactively on the command line or
       script controlled with usually elevated privileges.

       For administrative tasks, the Veyon Configurator and the command line tool  Veyon  Control
       are available. Veyon Control can be started via the command veyon-cli in the command line.
       If the Veyon installation directory is not in the $PATH  environment  variable,  you  must
       first change to the installation directory or prepend the directory to the program name.

       Veyon  Control  falls  into  various control modules. For each module a set of commands is
       available.

       Available modules are:

       authkeys
              Commands for managing authentication keys

       config Commands for managing the configuration of Veyon

       ldap   Commands for configuring and testing LDAP/AD integration

       networkobjects
              Commands for managing the builtin network object directory

       remoteaccess
              Remote view or control a computer

       service
              Commands for configuring and controlling Veyon Service

       shell  Commands for shell functionalities

              If the veyon-cli command is called with the help parameter, a list of all available
              modules is displayed. The list can vary depending on the installed Veyon plugins.

              Each module supports the help command, so that a list of all available commands can
              be displayed for each module.

AUTHKEYS MODULE

       The authkeys module allows the management of authentication keys so that common operations
       such as importing an authentication key or assigning a user group can be easily automated.

       create <NAME>
              This  command  creates a new pair of authentication keys and stores the private and
              public keys in the configured key directory. The parameter must be a name  for  the
              key, which may only contain letters.

       delete <KEY>
              This  command  deletes  the  <KEY>  authentication  key  from  the  configured  key
              directory. Please note that a key cannot be recovered once it has been deleted.

       export <KEY> [<FILE>]
              This command exports the <KEY> to <FILE>  authentication  key.  If  <FILE>  is  not
              specified, the file name is derived from the name and type of <KEY>.

       extract <KEY>
              This  command  extracts the public key part from the private key <KEY> and saves it
              as the associated public key. When  setting  up  another  master  computer,  it  is
              therefore  sufficient  to  transfer  the  private  key.  The public key can then be
              extracted.

       import <KEY> [<FILE>]
              This command imports the authentication key <KEY> from <FILE>.  If  <FILE>  is  not
              specified, the file name is derived from the name and type of <KEY>.

       list [details]
              This  command  lists  all  available  authentication  keys  in  the  configured key
              directory. If the details option is specified, a table with key details  is  output
              instead.  Some  details  may  be  missing  if a key cannot be accessed, e.g. due to
              missing read permissions.

       setaccessgroup <KEY> <ACCESS GROUP>
              This command adjusts the file access permissions on the <KEY> so that only the user
              group <ACCESS GROUP> has read access to it.

CONFIG MODULE

       Available commands for the config module are:

       clear  Clear  system-wide  Veyon  configuration.  This  command  resets  the  entire local
              configuration by deleting all configuration keys. Use this command  to  recreate  a
              defined state before importing another configuration:

                  veyon-cli config clear

       export Export  configuration to given file.This command exports the local configuration to
              a file. The name of the  destination  file  must  be  specified  as  an  additional
              parameter:

                  veyon-cli config export myconfig.json

       get    Read  and  output  configuration value for given key. This command allows reading a
              single configuration key. The name of the key must be supplied as a parameter.

                  veyon-cli config get Network/PrimaryServicePort

       import Import configuration from given file. This command imports  a  previously  exported
              configuration file into the local configuration. The name of the configuration file
              to be imported must be specified as an additional argument:

                  veyon-cli config import myconfig.json

       list   List all  configuration  keys  and  values.  This  command  shows  a  list  of  all
              configuration keys and their corresponding values.

                  veyon-cli config list

              Using  this  command  you  can find the names of configuration keys in order to get
              oder set them one by one.

       set    Write  given  value  to  given  configuration  key.  With  this  command  a  single
              configuration key can be written. The name of the key and the desired value must be
              passed as additional arguments:

                  veyon-cli config set Network/PrimaryServicePort 12345

                  veyon-cli config set Service/Autostart true

                  veyon-cli config set UI/Language de_DE

       unset  Unset (remove) given configuration key. This command deletes a single configuration
              key  resulting  in  Veyon using the internal index:`default value for this key. The
              name of the key must be passed as an additional argument:

                  veyon-cli config unset Directories/Screenshots

       upgrade
              Upgrade and save configuration of  program  and  plugins.  With  this  command  the
              configuration  of  Veyon  and  all  plugins  can  be updated and saved. This may be
              necessary if settings or configuration formats  have  changed  due  to  program  or
              plugin updates.

LDAP MODULE

       There  are  several LDAP specific operations provided through Veyon Control All operations
       are provided through the LDAP module. All lists of all supported commands  is  printed  on
       entering

           veyon-cli ldap help

       whereas command specific help texts can be shown via

           veyon-cli ldap help <command>

       The available commands are:

       autoconfigurebasedn
              This  command  can  be  used  to  automatically  determine  the  used  Base  DN and
              permanently write it to the configuration. An LDAP  server  URL  and  optionally  a
              naming context attribute have to be supplied as parameters:

                  veyon-cli ldap autoconfigurebasedn ldap://192.168.1.2/ namingContexts

                  veyon-cli                        ldap                       autoconfigurebasedn
              ldap://Administrator:MYPASSWORD@192.168.1.2:389/

       query  This command allows querying LDAP objects (rooms, computers, groups, users) and  is
              designed  mainly for debugging purposes. However, the function can also be used for
              developing scripts that may be helpful for system integration.

                  veyon-cli ldap query users

                  veyon-cli ldap query computers

NETWORKOBJECTS MODULE

       Veyon provides a built-in network object directory that can be used when no LDAP server is
       available.  This network object directory can be managed in the Veyon Configurator as well
       as on the command line. Certain operations such as CSV import are currently only available
       on  the command line. For most commands, a detailed description with examples is available
       in the command-specific help. The following commands can be  used  in  the  NETWORKOBJECTS
       module:

       add <TYPE> <NAME> [<HOST ADDRESS> <MAC ADDRESS> <PARENT>]
              This command adds an object, where <TYPE> can be room or computer.  <PARENT> can be
              specified as name or UUID.

       clear  This command resets the  entire  network  object  directory,  i.e.  all  rooms  and
              computers  are  removed. This operation is particularly useful before any automated
              import.

       dump   This command outputs the complete network object directory as a  flat  table.  Each
              property such as object UID, type or name is displayed as a separate column.

       export <FILE> [room <ROOM>] [format <FORMAT-STRING-WITH-VARIABLES>]
              This command can be used to export either the complete network object dictionary or
              only the specified room to a text file. The formatting  can  be  controlled  via  a
              format  string  and the variables it contains, so that, for example, a CSV file can
              be generated. Valid variables are %type%, %name%, %host%, %mac% and %room%. Various
              examples are given in the command help (veyon-cli networkobjects help export).

       import  <FILE>  [room  <  SPACE>] [format <FORMAT-STRING-WITH-VARIABLES>] [regex <REGULAR-
       EXPRESSION-WITH-VARIABLES>]
              This command can be used to import a text file into the network  object  directory.
              The processing of the input data can be controlled via a format string or a regular
              expression  and  contained  variables.  This  way  both  CSV  files  and  otherwise
              structured  data  can  be  imported.  Valid variables are %name%, %host%, %mac% and
              %room%. Various examples are given in the command  help  (veyon-cli  networkobjects
              help import).

       list   This  command  prints  the  complete  network object directory as a formatted list.
              Unlike the dump command, the hierarchy of rooms and  computers  is  represented  by
              appropriate formatting.

       remove <OBJECT>
              This  command  removes  the  specified  object  from the directory. <OBJECT> can be
              specified as name or UUID. When a room is removed, all computers  in  it  are  also
              removed.

REMOTEACCESS MODULE

       The  remoteaccess  module  provides  functions for a graphical remote access to computers.
       These are the same function that can be accessed from the Veyon Master. For  example,  the
       function  provided  by  the command line tool can be used to create a program shortcut for
       direct access to a particular computer.

       control
              This command opens a window with the remote control function that can  be  used  to
              control  a remote computer. The computer name or IP address (and optionally the TCP
              port) must be passed as an argument:

                  veyon-cli remoteaccess control 192.168.1.2

       view   This command opens a window with the remote  view  function  to  monitor  a  remote
              computer.  In  this  mode  the  screen  content  is  displayed  in  real  time, but
              interaction with the computer is not possible until the corresponding button on the
              tool bar has been clicked. The computer or IP address (and optionally the TCP port)
              has to be passed as an argument:

                  veyon-cli remoteaccess view pc5:5900

SERVICE MODULE

       The local Veyon Service can be controlled using the service module.

       register
              This command registers the Veyon Service in the operating system as  a  service  so
              that it starts automatically when the computer starts up.

                  veyon-cli service register

       unregister
              This  command  removes the service registration in the operating system so that the
              Veyon Service will not start automatically on startup.

                  veyon-cli service unregister

       start  This command starts the Veyon Service.

                  veyon-cli service start

       stop   This command stops the Veyon Service.

                  veyon-cli service stop

       restart
              This command restarts the Veyon Service.

                  veyon-cli service restart

       status This command queries and displays the status of the Veyon Service.

                  veyon-cli service status

SHELL MODULE

       Simple shell functionalities are provided by the shell module. If this  module  is  called
       without  further arguments, an interactive mode is started. In this mode, all CLI commands
       can be entered direcliy without having to specify and call the veyon-cli program for  each
       command. The mode can be exited by entering the keyword exit.

       Additionally the module can be used for automated processing of commands in a text file in
       order to implement simple batch processing:

       run <FILE>
              This command executes the commands  specified  in  the  text  file  line  by  line.
              Operations are executed independently of the result of previous operations, i.e. an
              error does not lead to termination.
