Slightly modified version of a remote Python pdb session found elsewhere. Just had to add SO_REUSEADDR socket option.

remote_pdb.py

#!/bin/env python

# Taken from http://www.dzone.com/snippets/remote-debugging-python-using
#   Only added the SO_REUSEADDR socket option since I hit the breakpoint often

import pdb, socket, sys

class Rdb(pdb.Pdb):
  def __init__(self, port=4444):
    self.old_stdout = sys.stdout
    self.old_stdin = sys.stdin
    self.skt = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    self.skt.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    self.skt.bind((socket.gethostname(), port))
    self.skt.listen(1)
    (clientsocket, address) = self.skt.accept()
    handle = clientsocket.makefile('rw')
    pdb.Pdb.__init__(self, completekey='tab', stdin=handle, stdout=handle)
    sys.stdout = sys.stdin = handle

  def do_continue(self, arg):
    sys.stdout = self.old_stdout
    sys.stdin = self.old_stdin
    self.skt.close()
    self.set_continue()
    return 1

  do_c = do_cont = do_continue

# Example usage - connect with 'telnet <hostname> 4444'
