Linux Firewalls (2nd Edition)

Description: Good points: * Lots of details about how to set up packet filtering in Linux. * Good reference material about various ports & services. Bad points: * The command lines in his "rc.firewall" scripts are long and thus wrap when printed in the book, making the scripts VERY difficult to read. A smaller, fixed-pitch font for the scripts, and good use of column alignment would have helped tremendously. * Scant discussion of the "hosts.allow" and "hosts.deny" files, or of TCP/IP wrappers and inetd. Both are an essential part of Linux firewalls. * The overall organization of the book is good, but some of the detail in the chapters is not well organized. Since he protects against invalid packets going OUT as well as coming IN, there's a lot of detail that many people will not want. That detail tends to obscure the WHY of what he's doing. * In the appendix, he lists in exhaustive detail all his firewall rules, and then lists them AGAIN in a "better" order. Yes, the second order is better for .. ISBN: 0735710996 Release Date: 24 October, 2001 List Price: $34.99 Author: Robert Ziegler Publisher: Que Last Updated: 06/26/2003
