Talk:Killerwall

What is killerwall?

Killerwall is a firewalling script for Linux 2.2.x and/or 2.4.x using either ipchains or iptables. It is a bash shell script (I know the top of the file says #!/bin/sh, but for most Linux distro's, that is a symbolic link to /bin/bash or /usr/bin/bash). The madness behind that is to use entirely POSIX tools to do it's job (sed, grep, awk...etc).
