read_nonblocking error in pxssh

[Sean DiZazzo]

Just glanced at the docs, but it might be worth a shot...

try:

> >>> import pxssh
> >>> s=pxssh.pxssh()
> >>> s.login("myhost","root","mypass", auto_prompt_reset=False)

Maybe???

Otherwise, I have used and modified this script with great success:

(ssh_session.py) http://www.koders.com/python/fidA430838E5789710E4DCF34C414AD75EB4EEE63CF.aspx

Good luck.
