How do I attach a remote debugger to a Python process?

Question

I\'m tired of inserting

import pdb; pdb.set_trace()

lines into my Python programs and debugging through the console. How do I connect a rem

A little bit late, but here is a very lightweight remote debugging solution courtesy of http://michaeldehaan.net/post/35403909347/tips-on-using-debuggers-with-ansible:

1. pip install epdb on the remote host.
2. Make sure your firewalling setup is not allowing non-local connections to port 8080 on the remote host, since epdb defaults to listening on any address (INADDR_ANY), not 127.0.0.1.
3. Instead of using import pdb; pdb.set_trace() in your program, use import epdb; epdb.serve().
4. Securely log in to the remote host, since epdb.connect() uses telnet.
5. Attach to the program using python -c 'import epdb; epdb.connect()'.

Adjust the security bits to suit your local network setup and security stance, of course.
