x2go.client module

x2go.client.X2GoClient is a public API class. Use this class in your Python X2Go based applications. Use it as a parent class for your own object oriented x2go.client.X2GoClient‘ish class implementation.

Supported Features

Supported features are:

  • X2Go multi-session management
  • keep track of initiated sessions
  • grant access to X2Go client config files: settings, printing, sessions and xconfig (Windows only) as normally found in ~/.x2goclient
  • instantiate an X2Go session by a set of Python parameters
  • load a session profile from x2goclient’s sessions configuration file and start the—profile-based pre-configured—session
  • sharing of local folders with remote X2Go sessions
  • enabling and mangaging X2Go printing (real printing, viewing as PDF, saving to a local folder or executing a custom »print« command
  • transparent tunneling of audio (Pulseaudio, ESD)
  • sharing of other desktops
  • LDAP support for X2Go server clusters (NOT IMPLEMENTED YET)

Non-Profile Sessions

A new non-profile based X2Go session within an x2go.client.X2GoClient instance is setup in the following way:

  • import the Python X2Go module and call the session constructor:

    import x2go
    x2go_client = x2go.X2GoClient()
    
  • register a new x2go.client.X2GoClient session; this creates an x2go.session.X2GoSession instance and calls its constructor method:

    x2go_sess_uuid = x2go_client.register_session(<many-options>)
    
  • connect to the session’s remote X2Go server (SSH/Paramiko):

    x2go_client.connect_session(x2go_sess_uuid)
    
  • via the connected X2Go client session you can start or resume a remote X-windows session on an X2Go server now:

    x2go_client.start_session(x2go_sess_uuid)
    

    resp.:

    x2go_client.resume_session(x2go_sess_uuid, session_name=<session_name_of_resumable_session>)
    
  • a list of available sessions on the respective server (for resuming) can be obtained in this way:

    x2go_client.list_sessions(x2go_sess_uuid, session_name=<session_name_of_resumable_session>)
    

Profiled Sessions

A new profile based X2Go session (i.e. using pre-defined session profiles) within an x2go.client.X2GoClient instance is setup in a much easier way:

  • import the Python X2Go module and call the session constructor:

    import x2go
    x2go_client = x2go.X2GoClient()
    
  • register an X2GoClient session based on a pre-configured session profile:

    x2go_sess_uuid = x2go_client.register_session(profile_name=<session_profile_name>)
    
  • or alternatively by the profile id in the »sessions« file (the name of the [<section>] in the »sessions« file:

    x2go_sess_uuid = x2go_client.register_session(profile_id=<session_profile_id>)
    
  • now you proceed in a similar way as shown above:

    x2go_client.connect_session(x2go_sess_uuid)
    x2go_client.start_session(x2go_sess_uuid)
    

    resp.:

    x2go_client.resume_session(x2go_sess_uuid, session_name=<session_name_of_resumable_session>)
    

Session Suspending / Terminating

You can suspend or terminate your sessions by calling the follwing commands:

x2go_client.suspend_session(x2go_sess_uuid)

resp.:

x2go_client.terminate_session(x2go_sess_uuid)
class x2go.client.X2GoClient(control_backend='PLAIN', terminal_backend='PLAIN', info_backend='PLAIN', list_backend='PLAIN', proxy_backend='NX3', profiles_backend='FILE', settings_backend='FILE', printing_backend='FILE', broker_url=None, broker_password=None, broker_noauth=False, client_rootdir=None, sessions_rootdir=None, ssh_rootdir=None, start_xserver=False, start_pulseaudio=False, use_cache=False, use_listsessions_cache=False, auto_update_listsessions_cache=False, auto_update_listdesktops_cache=False, auto_update_listmounts_cache=False, auto_update_sessionregistry=False, auto_register_sessions=False, no_auto_reg_pubapp_sessions=False, refresh_interval=5, pulseaudio_installdir='/home/mike/MyDocuments/4projects/x2go-upstream/python-x2go/docs/source/pulseaudio', logger=None, loglevel=56)[source]

Bases: object

The X2GoClient implements _THE_ public Python X2Go API. With it you can construct your own X2Go client application in Python.

Most methods in this class require that you have registered a session with a remote X2Go server (passing of session options, initialization of the session object etc.) and connected to it (authentication). For these two steps use these methods: L{X2GoClient.register_session()} and L{X2GoClient.connect_session()}.

Register a new x2go.session.X2GoSession. Within one x2go.client.X2GoClient instance you can manage several x2go.session.X2GoSession instances on serveral remote X2Go servers under different user names.

These sessions can be instantiated by passing direct x2go.session.X2GoSession parameters to this method or by specifying the name of an existing session profile (as found in the x2go.client.X2GoClient‘s sessions configuration node.

A session profile is a pre-defined set of session options stored in a sessions profile node (e.g. a configuration file). With the FILE backend such session profiles are stored as a file (by default: ~/.x2goclient/sessions or globally (for all users on the client) in /etc/x2goclient/sessions).

Python X2Go also supports starting multiple X2Go sessions for the same session profile simultaneously.

This method (L{X2GoClient.register_session()}) accepts a similar set of parameters as the x2go.session.X2GoSession constructor itself. For a complete set of session options refer there.

Alternatively, you can also pass a profile name or a profile id to this method. If you do this, Python X2Go tries to find the specified session in the sessions configuration node and then derives the necessary session parameters from the session profile configuration. Additional x2go.session.X2GoSession parameters can also be passed to this method—they will override the option values retrieved from the session profile.

Parameters:
  • server (str) – hostname of the remote X2Go server (Default value = None)
  • profile_id (str) – id (config section name) of a session profile to load from your session config (Default value = None)
  • profile_name (str) – name of a session profile to load from your session config (Default value = None)
  • session_name (str) – session name to register (by its name) (Default value = None)
  • allow_printing (bool) – enable X2Go printing support for the to-be-registered X2Go session (Default value = False)
  • allow_share_local_folders (bool) – set local folder sharing to enabled/disabled (Default value = False)
  • share_local_folders (list) – a list of local folders (as strings) to be shared directly after session start up (Default value = [])
  • allow_mimebox (bool) – enable X2Go MIME box support for the to-be-registered X2Go session (Default value = False)
  • mimebox_extensions (list) – MIME box support is only allowed for the given file extensions (Default value = [])
  • mimebox_action (str) – MIME box action to use on incoming MIME job files (Default value = ‘OPEN’)

Parameters:
  • session_uuid (str) – the X2Go session’s UUID registry hash
  • session_name (str) – the server-side name of an X2Go session (for non-associated session suspend) (Default value = None)
  • match_profile_name (str) – only suspend a session if this profile name matches (Default value = None)
