When something goes wrong with your Linux firewall, you need to fix it—right now. You don't have time for endless newsgroup searches, confusing man pages, emails to the developers... it's an emergency! One book brings together all the step-by-step solutions and proven problem-solving techniques you'll need when the time comes: Troubleshooting Linux® Firewalls .

Authors Michael Shinn and Scott Shinn are among the world's leading firewall experts; they've even been hired to protect computer security at the White House. In this book, they cover every area where Linux firewalls can go wrong: rules and filtering problems, Layer 2/3/4 issues, trouble with individual services, DNS/DHCP failures, even misconfigured VPNs. They also present an easy, start-to-finish troubleshooting methodology that'll help you identify even the newest or most obscure firewall problem fast—and solve it!

Inside, you will find in-depth information on the following areas:

  • What you must know about iptables and netfilter to troubleshoot and avoid problems

  • Using loggers, sniffers, and other tools to diagnose even the most obscure firewall problems

  • Making sure your firewall rules work the way they're supposed to

  • Resolving problems with Network Address Translation and IP Forwarding

  • Troubleshooting SMTP, Apache, Squid, NFS, FTP, instant messaging, and other Web-based services

  • Finding and fixing common problems with IPsec VPN configuration

  • Making your firewalls more failure-resistant: recommendations from the experts

If you depend on a Linux firewall, what will you do if it goes down? With Troubleshooting Linux® Firewalls , you can be confident that the solutions are right at hand—so you can sleep at night!

Best of breed April 20 2005
By Stephen Northcutt - Published on Amazon.com
Format: Paperback
The Shinn brothers are legendary in information security, so when I saw this book, I made sure to put it on the top of my airline reading list.

If you ever watch someone closely that is trying to troubleshoot a computer, network, or firewall, you quickly realize fault detection and root cause determination are skills very few people have. I watch people change two things and reboot, or try the last thing they just tried again and just shake my head.

The book is not just about troubleshooting, it includes setup, network theory, and proper design as well. However, chapter 4 should be required reading for anyone that is allowed near a computer with privileged access, windows or unix. If this book gets revised I would love to see the troubleshooting chapter expanded, that is critially important information.

It Delivers Aug. 24 2007
By Jeff Pike - Published on Amazon.com
Format: Paperback
Despite a number of introductory chapters, there is not much fluff in here. It provides a sound treatment of architectural issues before getting down to business with netfilter and iptables. It touches on some diagnostics techniques and tools before dealing with firewall configurations that are specific to popular services. This is a very useful book for firewall administrators. The index could be better, but I've been able to find what I needed.

Chapters in this 360 page volume include:
-Introduction
-Getting Started
-Local Firewall Security
-Troubleshooting Methodology
-The OSI Model
-netfilter and iptables Overview
-Using iptables
-A Tour of Our Collective Toolbox
-Diagnostics
-Testing Your Firewall Rules for Security
-Layer 2/Inline Filtering
-NAT and IP Forwarding
-General IP
-SMTP
-Web Services
-File Services
-Instant Messaging
-DNS/DHCP
-VPNs

Dead Links July 29 2012
By Patrick G. Heck - Published on Amazon.com
Format: Paperback
This book does contain a lot of good information, including a recipe for a shell script that establishes a basic firewall, and a chapter on troubleshooting. The explanations of the various parts of the script are ok, but the book is now 7 years old. Unfortunately, nearly every section in the book (including some explanations of things done in the firewall script) says "see our website for more info." That would be fine except the website no-longer exists, and the address now redirects to a commercial product. (which is why I'm not mentioning the site by name here).
