x11 forwarding with paramiko

Question

I\'m trying to run a command with paramiko that should be able to open an X window. The script I\'m using would something as follows:

import par         


        

Answer 1

Thanks Gary van der Merwe and dnozay for their code. The code below heavily relies on it and serves for running X programs on Windows. The notable difference is using select.select instead of poll, as poll is not available in Windows. Any improvements or corrections are welcome.

import select
import sys
import paramiko
import Xlib.support.connect as xlib_connect
import os
import socket
import subprocess



# run xming
XmingProc = subprocess.Popen("C:/Program Files (x86)/Xming/Xming.exe :0 -clipboard -multiwindow")
ssh_client = paramiko.SSHClient()
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh_client.connect(SSHServerIP, SSHServerPort, username=user, password=pwd)
transport = ssh_client.get_transport()
channelOppositeEdges = {}

local_x11_display = xlib_connect.get_display(os.environ['DISPLAY'])
inputSockets = []

def x11_handler(channel, (src_addr, src_port)):
    local_x11_socket = xlib_connect.get_socket(*local_x11_display[:3])
    inputSockets.append(local_x11_socket)
    inputSockets.append(channel)
    channelOppositeEdges[local_x11_socket.fileno()] = channel
    channelOppositeEdges[channel.fileno()] = local_x11_socket
    transport._queue_incoming_channel(channel)

session = transport.open_session()
inputSockets.append(session)
session.request_x11(handler = x11_handler)
session.exec_command('xterm')
transport.accept()

while not session.exit_status_ready():
    readable, writable, exceptional = select.select(inputSockets,[],[])
    if len(transport.server_accepts) > 0:
        transport.accept()
    for sock in readable:
        if sock is session:
            while session.recv_ready():
                sys.stdout.write(session.recv(4096))
            while session.recv_stderr_ready():
                sys.stderr.write(session.recv_stderr(4096))   
        else: 
            try:
                data = sock.recv(4096)
                counterPartSocket  = channelOppositeEdges[sock.fileno()]
                counterPartSocket.sendall(data)
            except socket.error:
                inputSockets.remove(sock)
                inputSockets.remove(counterPartSocket)
                del channelOppositeEdges[sock.fileno()]
                del channelOppositeEdges[counterPartSocket.fileno()]
                sock.close()
                counterPartSocket.close()

print 'Exit status:', session.recv_exit_status()
while session.recv_ready():
    sys.stdout.write(session.recv(4096))
while session.recv_stderr_ready():
    sys.stdout.write(session.recv_stderr(4096))
session.close()
XmingProc.terminate()
XmingProc.wait()
