ssh connections?

[Laura Uixera Cotano]

Hi!

I'm new in Python and I have to make a ssh connection to a proxy server.
Can you tell me how can I do it? 
I've tried to find something useful, but I didn't find anything in books or
in the internet. 
I have installed the version 1.5.2 of Python. Do you know if I need to
install a newer one to use ssh connections?
If you can tell me where can I find more information, please tell me.

Thx
