PS you don't fancy getting IP firewalling working on my box on sunday, I'm stuck.
iptables or ipchains? I've got a nicely downloaded bash script for IP tables laying about if you want it, its worked for me for a while now (basically since shifting to kernel 2.4). I use it because I haven't had time as yet to get my head round iptables, ipchains where far simpler in comparison.
Cheers,
Brett
