[a lot of code involving ssh and paramiko]

Here's a few general suggestions:

1) Try to reduce this to the smallest possible amount of code which 
demonstrates the problem.  You gave us a page full of complicated stuff.  
Keep hacking away lines of code that don't change the behavior until you 
get it down to something small and understandable.

2) Try to eliminate environmental problems.  You're running this under 
django?  Does it work as a stand-alone process (i.e. without django)?

Also, what is the context (Is it running in a Django view; a model? a
signal handler? in settings?)?

When replying can you please ensure we have the complete context, 
otherwise we have to spend time looking, thanks.
