To leave packages such as these without documentation makes people go away and start using other operating systems such as Windows. What I hope that this tutorial do, is that it gives people new knowledge about the Linux firewalling possibilities, how they work, and a general knowledge of how to set it up properly.

By that time, I went up to the second or third step on the ladder to becoming a “Linux Guru” I got saved from the Windows hell and started preachingand I think I’m still stuck somewhere around there.

The iptables-tutorial is currently rather stable, and contains information on all the currently available matches and targets in kernelas well as andreassoh couple of complete example scripts and explanations. This is about the same size as the iptables tutorial, but is elementary and guides a total new user to Linux through their first experience. Anyway, my aims aandreasson this documentation is to get more people to understand the extremely advanced routing functionalities that really are part of Linux.

Some good examples of what this document will contain is explanations on how the ip command works and the syntax, how all the different options and sndreasson to the command is used and information on how each “subcommand” works. The first time around I never got it to install at all. I think that this project will look a lot like the iptables tutorial when it gets going, especially in writing style and how it will be built up with a lot of examples among other things.

What do you feel is the most common Linux system vulnerability? However, the percentage of users doing the latter is a dwindling small amount of people, I think. Why did you decide to write the iptables reference? One of the main problems of Linux today is in my way of seeing things, that there is a huge lack of documentation, especially when you start digging into the deeper aspects of Linux.
