for similar tasks, I use pexpect http://pypi.python.org/pypi/pexpect.
spawning bash process and simulate an interactive session. Here sending ls
command, retrieving results and exiting. In the spawned process ssh or any
other command, is just another command.

Subject: SSH utility
Hi all,
I'm looking for a python library that lets me execute shell commands
on remote machines.
I've tried a few SSH utilities so far: paramiko, PySSH and pssh;
unfortunately all been unreliable, and repeated questions on their
respective mailing lists haven't been answered...
It seems like the sort of commodity task that there should be a pretty
robust library for. Are there any suggestions for alternative
libraries or approaches?
Thanks!
James
