SSH utility

[Edwin.Madari at VerizonWireless.com]

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.

>>> c.sendline('ls')

>>> c.before, c.after
('exit\r\nexit\r\n', <class 'pexpect.EOF'>)
>>> exit()

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
