OS specific command in Python

[diffuser78 at gmail.com]

Hi Avell,

I want to communicate using subprocess module but my task is a little
different. May be you can guide me.

I have a linux box, from where I remotely execute all the commands. The
remote machine is windows machine. I installed an OpenSSH server for
windows to send the shutdown command. I setup the public keys in such a
way that I could login to SSH server without using password.

I used

import os
os.system('ssh Admin at IP_ADDRESS shutdown -s')


I was wondering how can I interact with an application . Since you
mentioned about subprocess module, I want a ability that my PYthon
script can actually interact with the windows box and launch and close
application there remotely.

Any suggestions on how to do this ?

Every help is appreciated.

Thanks for your time
