X2GoFwServer implements a gevent's StreamServer based Paramiko/SSH port forwarding server.

An X2GoFwServer class object is used to tunnel graphical trafic through an external proxy command launched by a X2GoProxy* backend.

Method Details

init(self, listener, remote_host, remote_port, ssh_transport, session_instance=None, session_name=None, logger=None, loglevel=56)
(Constructor)

x.__init__(...) initializes x; see help(type(x)) for signature

Parameters:

listener (tuple) - listen on TCP/IP socket (<IP>, <Port>)
remote_host (str) - hostname or IP of remote host (in case of X2Go mostly 127.0.0.1)
remote_port (int) - port of remote host
ssh_transport (obj) - a valid Paramiko/SSH transport object
session_instance (obj) - the complete X2GoSession instance of the X2Go session this port forwarding server belongs to. Note: for new X2GoSession instances the object has the session name not yet set(!!!)
session_name (str) - the session name of the X2Go session this port forwarding server belongs to
logger (obj) - you can pass an X2GoLogger object to the X2GoFwServer constructor
loglevel (int) - if no X2GoLogger object has been supplied a new one will be constructed with the given loglevel

Overrides: object.__init__

x2go_forward_tunnel_handle(self, fw_socket, address)

Handle for SSH/Paramiko forwarding tunnel.

Parameters:

fw_socket (obj) - local end of the forwarding tunnel
address (tuple) - unused/ignored

stop(self)

Stop the forwarding tunnel.

Overrides: gevent.baseserver.BaseServer.stop
