I am not sure about the platform of the machine where i want to run the script? Please provide some sample code as well. I wont mind going for some other scripting language as well.

Answer 1

The simplest/quickest way would be to use Python's os.system() to call the ssh command of the system: http://docs.python.org/library/os.html?highlight=system#os.system

Eg this works on Ubuntu

import os
os.system('/usr/bin/ssh localhost ls -la /')

runs 'ls -la /' through ssh on localhost.

You will need to provide the proper command-line options to ssh, and you can set up the ssh keys to connect securely but without a password to a remote host for executing command(s): check this out: http://www.g-loaded.eu/2005/11/10/ssh-with-keys/ or google for more info on ssh keys.

Answer 2

You might want to take a look at Fabric :

Fabric is a Python library and command-line tool for streamlining the use of SSH for application deployment or systems administration tasks.

It provides a basic suite of operations for executing local or remote shell commands (normally or via sudo ) and uploading/downloading files, as well as auxiliary functionality such as prompting the running user for input, or aborting execution.

You should try execnet , it provide API to execute arbitrary Python code on remote machine. I use it on Linux machines but it work both in Windows and Linux.
