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 machine).

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 workarounds.

I googled & found people using several libraries to accomplish ssh to remote machine & execute a command on remote machine.
paramiko ( now forked into the ssh moduke), fabric, pushy ,etc

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
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

cheers

If 3/4 of the arguments are strings, what sort of objects are the other
1/4?

Use a dedicated remote procedure call library. Do not try to invent your
own. The wheel has already been invented, you are just wasting your time.

I've used both Pyro and Rpyc, either of them seem perfectly reasonable.
There are many others, but frankly I don't think there is a "best of
breed" that stands far ahead of the rest.

I understand the OP as meaning "three or four string arguments".

Sorry for the confusion Steven.
There are 3 or 4 arguments, all of which are strings.
I understand the OP as meaning "three or four string arguments".

Yup, that's what i meant.
