Red Hat Linux Firewalls

What I was looking for in this was a book explaining IPTABLES. What I got was much more. The book starts with overall theory and firewalls in practice, basics off the major network protocols, TCP, UDP, and then moves into the how-to's and breaks down the iptables commands. Script examples are great, already put some of his suggestions into practice. Would recommend to anyone building a Linux firewall.

I wish this book was released a year ago! I spent a great deal of time and energy figuring how to set up and configure a Linux IPTABLES firewall. I did it the hard way. I dug up information from many sources and finally accomplished my mission.This beauty of this book is that the author has put everything you need in one place. It gives the reader a good conceptual understanding of the concepts and then goes into detail on how to build your firewall. It also contains actual IPTABLES code that you can use with little modification.Great book! Thanks Bill.

Although I am not finished this book, halfway, I feel compelled to review it. The book has great humor, good info, and makes a very dry read interesting. Although it does not go into great detail on implementing firewalls in the real world, it does have all you need to get moving on your own. I wish that it covered implementation in greater detail but then again most linux guys want to "feel" smarter by figuring it out on their own.

I was looking for a good book on iptables and this book exceeded my expectations. RedHat Firewalls provides a great description of ipchains, iptables, and also some good sample scripts. In the past, I used the 'Linux Firewalls' book, but if you're running RedHat systems, this is the book for you.Half of the book was 'into to firewalls' stuff, which may come in handy for someone new to firewalls entirely. I would have preferred more info on troubleshooting.
