NAME
pyhoca-cli - X2Go command line client written in Python
SYNOPSIS
pyhoca-cli [ options ] [[<user>@]<host>]
DESCRIPTION
pyhoca-cli aims to be a cross-platform (Windows, Mac OS X, Linux) X2Go command line client written in
Python.
You can use it for scripting remote X2Go sessions or simply starting, resuming or shadowing X2Go sessions
from the command line in a terminal.
It supports versatile command line options as well as parsing x2goclient configuration files.
See the included README and TODO for further information on pyhoca-cli.
COMMON OPTIONS
pyhoca-cli accepts the following common options:
-h, --help
Display a help with all available command line options and exit.
-V, --version
Output version information and exit.
--quiet
No output to stdout at all!
-d, --debug
Enable debugging output.
--libdebug
Enable debugging code of the underlying Python X2Go module.
--libdebug-sftpxfer
--list-cmdline-features
Print a machine-readable list of client-side features to STDOUT and exit. Enable debugging code
of Python X2Go's sFTP server code (very verbose, and it may even reveal promiscuous data).
SERVER / SESSION PROFILE
You either have to specify a server name or a pre-configured X2GoClient session profile to tell pyhoca-
cli to what X2Go server to connect. pyhoca-cli will not start if neither of these two options has been
given on the command line.
--server <HOSTNAME_or_IP>
Legacy parameter, still supported, but using positional argument [<user>@]<host>] should become
your preferred syntax.
-P, --session-profile <SESSION_PROFILE_NAME>
The name of the session profile to be used to make the connection.
--non-interactive
Enforce non-interactive mode. Avoid any TTY interaction during runtime.
ACTIONS
pyhoca-cli accepts exclusively one of the listed actions:
-N, --new
Start a new X2Go session on server (default mode if no mode is explicitly specified).
--try-resume
When given with --new , try finding and resuming a session originally started with the same
command. If that fails, start a new session, finally.
-R, --resume <SESSION_NAME>
Resume existing X2Go session <SESSION_NAME> on server. Special values for <SESSION_NAME> are
,,NEWEST'' (will resume youngest session) or ,,OLDEST'' (resume session with oldest timestamp).
-D, --share-desktop <USER>@<DISPLAY>
Share an X2Go session on the remote server specified by <USER>@<DISPLAY>, whereas <USER> can be
the same user that is starting the share mode session or any other user that grants X2Go desktop
sharing for the current user.
-S, --suspend <SESSION_NAME>
Suspend running X2Go session <SESSION_NAME>. A special value for <SESSION_NAME> is ,,ALL'' (will
suspend all sessions of the connected user).
-T, --terminate <SESSION_NAME>
Terminate running X2Go session <SESSION_NAME>. A special value for <SESSION_NAME> is ,,ALL'' (will
terminate all sessions of the connected user).
-L, --list-sessions
List user's X2Go sessions on server.
--list-profiles
List user's X2Go session profiles configure on this client.
--from-stdin
For LightDM remote login integration: read <username> <host[:port]> <command> <password> from
STDIN' and start a new session, transfer a running session or resume a suspended session.
If there are several sessions running/suspended of the same desktop shell, then the first session
found will be transferred/resumed. If there are several sessions running with a different desktop
shell as session type (or even rootless sessions) none of these session will be touched unless any
of the discovered sessions match in the requested desktop shell (i.e. X2Go session type).
This option is only available for the Linux version of pyhoca-cli.
ACTION OPTIONS
pyhoca-cli actions can be tweaked by these options:
--clean-sessions
Clean all of the user's suspended/running sessions before starting a new one on the named X2Go
server.
--terminate-on-ctrl-c
Terminate the connected session when pressing CTRL+C (instead of suspending the session).
X2GO OPTIONS
-c, --command <CMD>
Command to run with --new mode on server (default: xterm).
-l, -u, --username <USERNAME>
Username for the session (default: currently logged in user).
--password <PASSWORD>
User password for this session. If a matching private SSH key is available this one will be pre‐
ferred for authentication. The cleartext password that has been specified at the command line will
be masqueraded in the systems process list (Linux, MacOS). On Windows systems the usage of the
--password option is forbidden.
--force-password
Enforce authentication with username and password, prohibit SSH public/private key authentication.
-p, --remote-ssh-port <R_PORT>
Remote X2Go server's SSH port (default: 22).
-i, -k, --ssh-privkey <SSH_PRIVKEY>
Use file <SSH_PRIVKEY> as private key for SSH connections (default: ~/.ssh/id_rsa).
--add-to-known-hosts
Add RSA/DSA host key to ~/.ssh/known_hosts if authenticity of server can't be established (de‐
fault: not set).
-A, --forward-sshagent
Enable SSH agent forwarding.
--sound {pulse|esd|none}
X2Go server's sound system (default: 'pulse').
-F, --share-local-folders <folder1>[,<folder2>[,...]]
A comma separated list of local folders that shall be made available in the remote X2Go session.
--printing
Use X2Go printing (default: disabled).
--share-mode {0|1}
Share mode for X2Go desktop sharing (0: view-only, 1: full access).
--kdrive
As graphical backend use the X2Go Kdrive Xserver instead of the default NXv3 Xserver.
--auth-attempts {0,1,2,3,...}
Number of interactive authentication attempts in case authentication with the server fails (wrong
password?). A value that equals 0 disables interactive authentication completely and requires that
a private SSH key has been given on the command line or in the session profile or that the --pass‐
word command line option is used.
BROKER OPTIONS
In case you want to retrieve X2Go session profiles from an X2Go Session Broker use the following options:
--broker-url=<URL>
Specify the <URL> of the X2Go Session Broker. pyhoca-cli can access http:// and ssh:// style URLs.
Syntax of <URL> for HTTP brokerage:
http(s)://<user>:<password>@<hostname>:<port>/path/to/broker
Syntax of <URL> for SSH brokerage:
ssh://<user>:<password>@<hostname>:<port>/usr/bin/x2gobroker (or any executable that provides the
broker via SSH).
--broker-password <password>
Session broker password for retrieving session profiles from the X2Go Session Broker. The cleart‐
ext password that has been specified at the command line will be masqueraded in the systems
process list (Linux, MacOS). On Windows systems the usage of the --broker-password option is for‐
bidden.
--broker-cacertfile=</path/to/cafile.crt>
NOT IMPLEMENTED YET: Specify a special (self-signed) root-CACert file that shall get used when
connecting to an X2Go Session Broker via https (SSL). (Not implemented, yet).
--broker-noauth
NOT IMPLEMENTED YET: The X2Go Session Broker is accessible without authentication.
--auth-id=<USERNAME>
NOT IMPLEMENTED YET: Use this <USERNAME> for authenticating against the X2Go Session Broker. This
option mostly makes sense together with --broker-autologin or --broker-ssh-key. (Not implemented,
yet).
--broker-autologin
NOT IMPLEMENTED YET: For SSH based X2Go Session Brokers. If an SSH agent is available or default
key files exist then try those for authentication against the X2Go Session Broker. (Not implement‐
ed, yet).
--broker-ssh-key=<SSHPRIVKEY>
NOT IMPLEMENTED YET: For SSH based X2Go Session Brokers. Full path to a valid SSH private key
file. (Not implemented, yet).
SESSION OPTIONS (NXv3 or X2GoKDrive)
-g, --geometry {<WIDTH>x<HEIGHT>|fullscreen|maximize}
Screen geometry (default: '800x600').
--dpi <DPI>
Launch X2Go session's Xserver with resolution <DPI> (in dots per inch).
--xinerama
Enable Xinerama support for multi-head setups. Requires X2Go Server 4.1.0.0 (or newer).
-q, --link {modem|isdn|adsl|wan|lan}
Link quality (default: 'adsl')
-C, --clipboard-mode {none|server|client|both}
Clipboard mode (default: ´both´ directions, other allowed values: ´none´ for no clipboard support,
´client´ to server copy+pasting only, ´server´ to client copy+pasting only)
-t, --session-type {desktop|application}
Session type (default: 'application'). Note: there are also some auto-detection feature for the
session type built into the code. It might not always happen what you expect from setting this
option.
--pack <PACK_METHOD>
Compression method (see below for possible values).
--kbd-layout {us|de|fr|...}
Use keyboard layout (default: 'null').
--kbd-type {auto|pc105/us|pc105/de|...}
Set Keyboard type (default 'auto'). Use auto as value here to enable X2Go's keyboard auto-detec‐
tion code.
BACKEND OPTIONS
pyhoca-gui supports transparent use of different data backends. For configuration three backends are com‐
mon: FILE, GCONF (Linux only) and WINREG (Windows only). The default backend currently is the FILE back‐
end on all platforms.
For client-server communication the only yet implemented backend is the STDOUT backend (as X2Go server
commands print their execution results to /dev/stdout. (But other communication backends might be possi‐
ble in the future...).
In the same way we are focusing on a successor of the current NX3 agent/proxy tool. A change in the proxy
backend will also be implemented as a backend.
--backend-controlsession <CONTROLSESSION_BACKEND>
Force usage of a certain CONTROLSESSION_BACKEND (do not use this unless you know exactly what you
are doing).
--backend-terminalsession <TERMINALSESSION_BACKEND>
Force usage of a certain TERMINALSESSION_BACKEND (do not use this unless you know exactly what you
are doing).
--backend-serversessioninfo <SERVERSESSIONINFO_BACKEND>
Force usage of a certain SERVERSESSIONINFO_BACKEND (do not use this unless you know exactly what
you are doing).
--backend-serversessionlist <SERVERSESSIONLIST_BACKEND>
Force usage of a certain SERVERSESSIONLIST_BACKEND (do not use this unless you know exactly what
you are doing).
--backend-proxy <PROXY_BACKEND>
Force usage of a certain PROXY_BACKEND (do not use this unless you know exactly what you are do‐
ing).
--backend-sessionprofiles <SESSIONPROFILES_BACKEND>
Use given backend for accessing session profiles, available backends on Linux: FILES, GCONF; on
Windows: FILES, WINREG.
--backend-clientsettings <CLIENTSETTINGS_BACKEND>
Use given backend for accessing the client settings configuration, available backends on Linux:
FILES, GCONF; on Windows: FILES, WINREG.
--backend-clientprinting <CLIENTPRINTING_BACKEND>
Use given backend for accessing the client printing configuration, available backends on Linux:
FILES, GCONF; on Windows: FILES, WINREG..SH COMPATIBILITY OPTIONS pyhoca-cli aims at being fully
compatible with all command line options and session config files of the X2Go project's X2Go com‐
mand line client x2goclient-cli as well as the x2goclient GUI. This is still work in progress. To
achieve this, some compatibility options have already been added:
--port <R_PORT>
Compatibility option, synonymous to --remote-ssh-port <R_PORT>.
--ssh-key <SSH_PRIVKEY>
Compatibility option, synonymous to --ssh-privkey SSH_KEY.
--use-sound {yes|no}
Compatibility option, synonymous to --sound {pulse|none}.
--client-ssh-port <PORT>
Compatibility option for the x2goclient GUI. PyHoca-Cli (resp. Python X2Go) brings its own inter‐
nal sFTP server. Thus, this option will be ignored.
NX COMPRESSION METHODS
As NX compression methods (--pack option) the following values are possible. The % character must be re‐
placed by a digit 0-9.
nopack, 8, 64, 256, 512, 4k, 32k, 64k, 256k, 2m, 16m 256-rdp, 256-rdp-compressed, 32k-rdp, 32k-rdp-com‐
