How can I make an SSH connection in Python 3.0? I want to save a file on a remote computer where I have password-less SSH set up.
You want all of the ssh-functionality implemented as a python library? Have a look at paramiko, although I think it's not ported to Python 3.0 (yet?).
If you can use an existing ssh installation you can use the subprocess way Dietrich described, or (another way) you could also use pexpect (website here).
