Hi PyTutor Folks

Here is my situation

1. I have two machines. Lets call them *local & remote.*
Both run ubuntu & both have python installed

2. I have a python script, *local.py*, running on *local *which needs to
pass arguments ( 3/4 string arguments, containing whitespaces like spaces,
etc ) to a python script, *remote.py* running on *remote* (the remote

I have the following questions:

1. What's the best way to accomplish my task ?
I have researched quite a bit & so far found really conflicting & complex

I googled & found people using several libraries to accomplish ssh to
remote machine & execute a command on remote machine.
paramiko <http://www.lag.net/paramiko/> ( now forked into the ssh
fabric <http://docs.fabfile.org/en/1.4.3/index.html>,

People who have used any of these libraries, which one would you recommend,
as the most apt (simple & easy to use, lightweight, best performance, etc)
for my situation ?

2. I would prefer a solution, which does NOT require the installation of
extra libraries on the local & remote machines.
If installing external librar

3. Has anybody been able to do this using os.system ?

I tried this
>>> import os
>>> *os.system ("ssh remoteuser at remote python remote.py arg1 arg2 arg3")*
This worked, but if the arguments i tried to pass, had spaces, i was not
able to 'escape' the spaces.

Any & all explanations/links/code
snippets/thoughts/ideas/suggestions/feedback/comments/ of the Python tutor
community would be greatly appreciated.

Thanks a ton
