The beauty of open source is making code freely available. The curse is trying to organize the chaos that code development can evolve into. CVS, the Concurrent Version System, is an open source tool for managing and distributing source code. It allows multiple users dispersed over a wide geographic area to work on the same file at the same time, using a shared directory. Under CVS, multiple users can check out files from a directory tree, make changes, and then commit those changes back into the directory. CVS is a pivotal tool on many projects involving information or software, whether in-house or conducted over the Internet.The CVS Pocket Reference is a quick reference guide to help administrators and users set up and manage source code development. This small book delivers the core concepts of version control along with a complete command reference and guide to configuration and repository set up. The book includes:
A version control primer that teaches the general concepts of version control and how it applies to CVS.Instructions on how to install and configure CVS for Unix®-like operating systems.Administrator and user sections, with complete listings of their respective commands and options for configuring and using CVS.Details on how to import files from RCS and SCCS directories into CVS.References to related useful materials.Much more than a quick list of commands and options, this little book is packed with a surprising amount of detail--including an overview of background concepts, thorough descriptions on how to use and administer a CVS repository, and discussions of CVS-related files and how to manage them--all in a convenient reference format. This edition covers the CVS 1.11 and includes new commands for querying a central CVS repository, new configuration parameters, and new options for setting up a server for remote access. The book is a perfect companion for open source developers. The CVS Pocket Reference also contains tips on common tasks, such as converting projects from other revision control formats to CVS. It''s an absolute must for developers who need an on-the-job guide for quick answers to CVS dilemmas.

Firewalls, Network Address Translation (NAT), network logging and accounting are all provided by Linux''s Netfilter system, also known by the name of the command used to administer it, iptables. The iptables interface is the most sophisticated ever offered onLinux and makes Linux an extremely flexible system for any kind of network filtering you might do. Large sets of filtering rules can be grouped in ways that makes it easy to test them and turn them on and off.Do you watch for all types of ICMP traffic--some of them quite dangerous? Can you take advantage of stateful filtering to simplify the management of TCP connections? Would you like to track how much traffic of various types you get?This pocket reference will help you at those critical moments when someone asks you to open or close a port in a hurry, either to enable some important traffic or to block an attack. The book will keep the subtle syntax straight and help you remember all the values you have to enter in order to be as secure as possible. The book has an introductory section that describes applications,followed by a reference/encyclopaedic section with all the matches and targets arranged alphabetically.
