There was a problem filtering reviews right now. Please try again later. Kindle Edition Verified Purchase. I still keep Linux Firewalls on my bookshelf.

It's a little dated and does not include coverage of firewalld and newer items, but the basics of iptables remain and this is still handy when I'm adjusting my firewalls for a new application, etc.

Never miss out on PAYBACK Points!

Still useful after all these years The original review is below: I use this book as a reference and that is how it appears to be written. It's the sort of book I want to have on my shelf so it's there when I need it.

Once my firewalling is setup I'm not futzing with it, so that knowledge goes out of my head; not like I'm configuring them every day. As a reference I find it'e well organized and provides quick access to the information I need, The coverage of iptables helps me get the firewalling task at hand done and to refresh my memory of iptables in's and out's. I've had this book for years. It got me started with linux firewalls, and it's still helpful when I have to dredge up that skill set even quite a while since I last used it.

I'm sure a lot of the content in this book is available online and some of that will certainly be newer or have some more info.

But I like having one place to go for what I need when I need it. This book has helped me to truly begin to understand how iptables works. I have previously used a Shorewall interface for working on a firewall, but I found that things were just a step or two too abstract for my liking. Linux Firewalls gave me a good not excessive! It really does not help you if you don't already know how to do important administrative tasks like assure that the firewall script is executed at the proper time, or know how to fill in the blanks of things that are not strictly Firewall related.

That's what I liked about this book, personally: It did not explain to me what a Shell was, or take 50 pages to describe the OSI model yet again! It just shows you how to do various things, and gives you the information you need to be able to go from there. I thought the book started out right, with some background on IP addresses, subnets, routing, and a definition of packet filtering. It also does a fairly good job describing what ipchains is, but it never put the whole picture together for me. The book kept repeating the same basic information about ipchains and then it gave many, many examples of the different permutations of commands and parameters to use to configure ipchains.

I would have rather had a complete description of the command and how best to use it along with some constructive examples. Also, the book never gave me a front to back picture of how packets flow through the firewall and are routed and filtered and in what order everything happens. If you don't have this book your probably outdated. Easy to read and looks beautiful in my library. One person found this helpful. Bought a paper book. A book was delivered to Russia into my hands in 3 days! From the very basic concepts to advanced but clear firewall setup, this book leads you to create a system that will optimally fit your needs.

My system implements lots of recommendations from this book. Thanks to authors, thanks to Amazon! One person found this helpful 2 people found this helpful. This book gets right down to business with no nonsense -- just what you need to know to set up ipchains firewall rules, and this is taken care of all the the first pages in the 1st edition.

After that it's more sage instruction on how to further harden your systems. Great book it covers all the themes I could expect, it assumes some networking knowledge.

Book is well written and needed to write you firewalls using iptables. I used the firewall rules contained within the book for my DMZ router at work and it never failed me.
