Some assorted projects of mine, some of which are security related, others that were made to fill my needs. All of them are shell-scripts, my personal coding done in Perl & C shouldn't be used by anyone except me (because it's mostly god-awful hacks).

Projects:
Blackhole: An iptables-configuration environment(ish), basically it's a framework to develop complex iptables scripts in.
Convmedia: A fairly simple, but powerful, collection of scripts for media conversion. Needs some love & simplification, but it gets the job done.
