Where can I find a book or articles that doesnt tell me how to do a ls. Im looking for one where i can learn about:

-iptables -apparmor

I know there is ufw and gufw and no gui for app armor. I want to learn iptables because I have a debian server and I dont think I can install ufw on it.

Thanks for reply.

Your local library is a good start. Amazon has a load of stuff about Linux – Ringtail Apr 12 '12 at 23:27

Per command/application/resource manuals are provided during installing, after which you can easily run man iptables and/or man apparmor in a terminal in order to view the syntax/usage of your desired application.

Good luck!
