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.
