Firewalls, Network Address Translation (NAT), and 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 on Linux 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 listings of all iptables options are divided into those suitable for firewalling, accounting, and NAT.

Most Perl programmers know about the Perl debugger--the nifty little built-in utility that you can use to fully debug any programs that you write. Inside the interactive debugger environment, you're prompted for commands that let you examine your source code, set breakpoints, dump out function call stacks, change values of variables, and much more. It's so convenient that some programmers run it just to test out Perl constructs as they create a program. But although it's on their radar, not many Perl programmers take the time to master the debugger. That's where the Perl Debugger Pocket Reference comes in. This little book provides a quick and convenient path to mastery of the Perl debugger and its commands. Written by a core member of the Perl debugger development team, it's an ideal quick reference to debugger commands, as well as a detailed tutorial on how to get started. The Perl Debugger Pocket Reference provides complete coverage in a conveniently small package. Maybe you write code so clean you never have to look at it twice. Or perhaps you'd rather focus your energies on writing clean code, rather than learning about the debugger.But if you need to learn about the Perl debugger in a hurry, the Perl Debugger Pocket Reference is the book you'll want to have close by. And you can always keep a copy on hand to share with programmers who need it more than you do. O'Reilly's Pocket References have become a favorite among programmers everywhere. By providing a wealth of important details in a concise, well-organized format, these handy books deliver just what you need to complete the task at hand.

This reference describes the functions, classes, and templates in that part of the C++ standard library of ten referred to as the Standard Template Library (STL). The STL encompasses containers, iterators, algorithms, and function objects, which collectively represent one of the most important and widely used subsets of standard library functionality. The C++ standard library, even the subset known as the STL, is vast. It's next to impossible to work with the STL without some sort of reference at your side to remind you of template parameters, function invocations, return types - indeed, the entire myriad of details you need to know in order to use the STL effectively and get work done. You need a memory-aid. Programmers familiar with the STL need a small, lightweight memory-aid. That's what the STL Pocket Reference is. It's small, lightweight, and chock-full of information that you can take in at a glance, so you can get on with your work.

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 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.; and references to related useful materials. Much more than a quick list of commands and options, the book is packed with 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. It also contains tips on common tasks, such as converting projects from other revision control formats to CVS.

Oracle has long supported the ANSI-standard LIKE predicate for rudimentary pattern matching, but regular expressions take pattern matching to a new level. They provide a powerful way to select data that matches a pattern, as well as to manipulate, rearrange, and change that data. This concise pocket guide is part tutorial and part quick-reference. It's suitable for those who have never used regular expressions before, as well as those who have experience with Perl and other languages supporting regular expressions. The book describes Oracle Database 10G's support for regular expressions, including globalization support and differences between Perl's syntax and the POSIX syntax supported by Oracle 10G. It also provides a comprehensive reference, including examples, to all supported regular expression operators, functions, and error messages.

Few .NET developers have the luxury of unlimited code testing once their application is complete, and rushing through the testing process is both problematic and stressful. The open source NUnit framework provides an excellent and efficient way to test and improve .NET code as it's written, saving hundreds of QA hours and headaches. NUnit is one of the most mature and widely-used .NET open source projects even Microsoft uses it internally. NUnit is a unit-testing framework for all .Net languages. Written entirely in C#, NUnit takes advantage of many .NET language features, such as custom attributes and other reflection related capabilities. It automates unit testing and reduces the effort required to frequently test code while developing it. NUint is invaluable for .NET developers in test-driven development under agile methodologies such as Extreme Programming (XP) as well as for developers who use for unit testing for software quality assurance.Unfortunately, some of those valuable hours saved by using NUnit can be wasted trying to master this powerful but under-documented framework Proof that good things come in small packages, the NUnit Pocket Reference is a complete reference to NUnit, filling in the blanks left by the existing documentation and online discussion. It offers developers everything they need to know to install, configure, and use NUnit; the NUnit user interface; and a reference to the NUnit framework classes in a slim but well-organized package. This handy little book even offers practical, real world NUnit examples. And with the NUnit Pocket Reference, IT managers will know to expect when they implement unit testing in their projects. It is the only book you'll need on this popular and practical new open source framework.

Oracle designed its database products to be flexible and configurable so they would operate on a variety of hardware platforms, and they succeeded--Oracle software runs on more than seventy computer platforms, from mainframes to PC networks to handheld PDAs. The secret to this flexibility lies in the software's initialization parameters, whose numerous settings can be configured for top performance in countless environments. On the downside, however, improper settings can slow a system down; even grind it to a halt. And with so many parameters--which change from version to version of Oracle software--it's challenging for Oracle administrators to keep in mind the characteristics and optimal settings for each parameter. The Oracle Initialization Parameters Pocket Reference provides the crucial information you need to make key adjustments to your Oracle database. This concise guide is a mix of invaluable performance tips and a quick reference to Oracle's initialization parameters.The book describes each initialization parameter, indicates what category it's in--from auditing to multi-threaded server MTS--and whether it can be modified dynamically via the ALTER SESSION or ALTER SYSTEM command. In addition to the details about parameter characteristics and settings, you'll find performance tips, such as how the various parameters interact, and what the most advantageous settings are for different configurations. No other reference focuses exclusively on these initialization parameters--an absolute must for anyone working with an Oracle database. Presented in a handy, easy-to-use format, the Oracle Initialization Parameters Pocket Reference is a welcome alternative for anyone who's struggled to memorize the best configuration settings or gone back and forth to online resources, trying to figure out what works. O'Reilly's Pocket References put the information you need close at hand where you need it most. This guide will keep your Oracle databases operating at peak performance.
