So you want to create a pex that packages your script and its dependencies?

Ok - first to make our script! Call it foo.py:

import requests

if __name__ == '__main__':
  req = requests.get("https://raw.githubusercontent.com/pantsbuild/pex/master/README.rst")
  print req.text.split("\n")[0]

SSH agent forwarding and screen

When connecting to a remote server via SSH it is often convenient to use SSH agent forwarding so that you don't need a separate keypair on that server for connecting to further servers.

This is enabled by adding the

ForwardAgent yes

option to any of your Host entries in ~/.ssh/config (or alternatively with the -A option). Don't set this option in a wildcard Host * section since any user on the remote server that can bypass file permissions can now als use keys loaded in your SSH agent. So only use this with hosts you trust.
