Linux iptables Pocket Reference

Summary: Concise, handy reference for working SysAdmins
Review: 'Linux iptables Pocket Reference' is an important and sorely needed reference to iptables, the interface to the Linux packetfilter used by System Admins to create firewalls, NAT routers, transparent proxies, and other 'magical' network devices. While not a tutorial, it offers good advice for those with a grasp of basic networking concepts, and a good notion of what a firewall is and what it is used for, in a dense and concise format. Sufficiently detailed information about the protocols involved obviate the need to keep additional references at hand, and make the work relatively self-contained. This should not be the first book you read about firewalls or tcp/ip, but if you are a networking professional, a technically oriented user, or just interested in creating special purpose network devices, this book belongs in your library. Those familiar with iptables will especially appreciate the lucid description of packet flow through the tables and chains, and the supporting diagrams ... they alone are worth the price of purchase.

If you have need for a book on the topic, you will not be disappointed with this one.

Summary: for sysadmins
Review: This book is written for linux/unix sysadmins, not programmers. The topic of iptables is intimately related to guarding a network against intruders. A sysadmin task. Plus, the compact, pocketbook size lends itself to a common scenario.

You're a harried sysadmin in the machine room of your company, surrounded by racks of computers and cabling. Equipment everywhere and little room for you to prop up a regular sized text on intrusion detection. Quite possibly, the master console is some cheezy old monitor that you got stuck with. Or even worse, it is just a terminal. If the latter, it's really awkward to do a man on iptables and also run it, especially if you're in real time mode against an active intruder. In other words, what this book is ideal for.
