[olug] IPCHAINS

[Nick Walter]

I'm not sure which book you were referring to, but a simple IPCHAINS setup
isn't very hard if you have some basic networking knowledge.

If you are running a single linux workstation, and it doesn't need to act as
a firewall for other computers, then your firewalling needs are quite
minimal.  You'll probably do more for your security by disabling unecessary
services than by setting up a firewall.  Do a "netstat -plan" and disable
anything listed in the LISTEN state that you don't need.

If you are trying to set up your linux box as a firewall to protect multiple
machines, you've got a lot bigger setup task ahead of you.  It's not
impossible, since I once was faced with the same challenge and it's
manageable with enough trial/error and howto reading.

As always, I suggest www.linuxdoc.org as a great resource for linux
documentation.
