Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I dont know enough to understand what all that meant. Are they saying that using a firewall for each user is better or worse, is there a safe way to have firestarter startup on its own without giving the root password? I dont understand?
well more or less linux is about security, and things such as a firewall should be only be ran as root, where you shouldn't be running firewall based apps as normal user, nor should you be able to edit the firewall configuration as a normal user (i.e. iptables)
and in the thread i gave you acid_kewpie went on to say that he can read up on sudo to allow a normal user to run something that requires root privledges...and he states "man sudo" to be typed in the terminal to get more information about sudo, and also there is your wonderful friend google that can give you even more informatoin.
Basically yes because that's the only safe way. You only want someone who knows the root password to be able to change the firewall's security settings. You can grant specific users the ability to not have to type in the password, but what if someone exploits your account, and then finds automatic root access to the system's firewall? Bad things is what...
If you configure firestarter, as root, and then exit, you are done. If you tell it you use DCHP, it will set itself up correctly. If you tell it to start the firewall automatically on ppp connect, it will write it's IP tables on connect, and you don't have to start it as root. i.e. configure it, and forget it. It puts the right stuff in runlevel 3 and 5 so that no matter how you boot up, it is armed. A regular user doesn't need to access it, and as a matter of fact, you can't even setuid it, it tells X on you and X blocks the ability to start GLCore libraries as setuid. Pretty cool extra I think.
Root, me, configured firestarter, and the rules apply to all users on the system. They never have to even think about it.
