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
andxconfig
(Windows only) as normally found in~/.x2goclient
communicate with X2Go Session Broker via http(s) or SSH
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—sessionsharing 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
published applications support
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 anx2go.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='/builddir/build/BUILD/python-x2go-0.6.1.3/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:
X2GoClient.register_session()
andX2GoClient.connect_session()

Register a new
x2go.session.X2GoSession
. Within onex2go.client.X2GoClient
instance you can manage severalx2go.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 thex2go.client.X2GoClient
’ssessions
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 (
X2GoClient.register_session()
) accepts a similar set of parameters as thex2go.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. Additionalx2go.session.X2GoSession
parameters can also be passed to this method—they will override the option values retrieved from the session profile.- Parameters:
