Blocking tor through iptables
I keep a database of tor hosts which gets updated quite often, and I have written a script in python which downloads the list and updates iptables so that they are all blocked.
It is recommended that the script gets added to cron so that the machines iptables keep up to date.
This script is ideal for schools and businesses to prevent people from circumventing content filtering, and also useful for servers to prevent abuse from ‘anonymous’ people who use tor for hacking for denial of service.
The script can be found here (http://www.andydixon.com/blocktor.py) and requires python (tested on v2.6)
