Hello Everyone, sorry to waste your time, I know this is a newbie question but I really need some help!
I am trying to setup a firewall on a debian machine. No matter which firewall software I try and run I still get the same message
ipchains: protocol not available.
I've tried to apt-get ipchains and it sais that I alrady have the newest version. Also when I try to setup a new rule "ipchains -N fw1" I get the same message.
So I guess the question is what did I do wrong? What do I do to fix it? and what type of firewall should I be running on a debian machine?
If you have a fairly recent version of debian (kernel version > 2.4) you will need to use iptables instead of ipchains. ipchains is older and used with the 2.2 version of the kernel.
