Ssh – How to run Yast with X and ssh

XDMCP is designed for this. On your server, you need to enable XDMCP support in your desktop manager:

• if you're using kdm, look for

  [Xdmcp]
  Enable=false
  

  at the end of your kdmrc, change false to true and restart kdm;

• if you're using lightdm, add

  [XDMCPServer]
  enabled=true
  port=177
  

  to /etc/lightdm/lightdm.conf and restart lightdm.

Then on your client, start X using

X -query ${SERVER_IP}

(with the appropriate IP address instead), and your server's login screen should show up on your client.

Perhaps somewhat off topic but this could be achieved with Python and the paramiko module:

#!/usr/bin/python2
import time
import paramiko

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('127.0.0.1', port=22, username='user', password='pass')

stdin, stdout, stderr = ssh.exec_command('su')
time.sleep(0.1) # some enviroment maybe need this.
stdin.write('root_password_goes_here\n')

[ add extra code here to execute a command ]

stdin.flush()
print (stdout.readlines())
ssh.close()

It should be noted that storing passwords in script generally is a bad idea from a security perspective. Make sure you have proper permissions set to the script (e.g. chmod 740)
