How to execute a process remotely using python

Question

I want to connect to and execute a process on a remote server using Python. I want to be able to get the return code and stderr (if any) of the process. Has anyone ever done anything like this before. I have done it with ssh, but I want to do it from Python script.

Cheers.

Answer 1

Use the ssh module called paramiko which was created for this purpose instead of using subprocess. Here's an example below:

from paramiko import SSHClient client = SSHClient() client.load_system_host_keys() client.connect("hostname", username="user") stdin, stdout, stderr = client.exec_command('program') print "stderr: ", stderr.readlines() print "pwd: ", stdout.readlines() 

UPDATE: The example used to use the ssh module, but that is now deprecated and paramiko is the up-to-date module that provides ssh functionality in python.
