                                  X2goFwServer

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, logger=None, loglevel=56)
(Constructor)

source code 

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 (instance) - a valid Paramiko/SSH transport object
  • logger (instance) - 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)

source code 

Handle for SSH/Paramiko forwarding tunnel.

Parameters:
  • fw_socket (instance) - local end of the forwarding tunnel
  • address (tuple) - unused/ignored

stop(self)

source code 

Stop the forwarding tunnel.

Overrides: gevent.baseserver.BaseServer.stop
