SendMail Cookbook

More often than not, the words "sendmail configuration" strike dread in the hearts of sendmail and system administrators--and not without reason. sendmail configuration languages are as complex as any other programming languages, but used much more infrequently--only when sendmail is installed or configured. The average system administrator doesn't get enough practice to truly master this inscrutable technology. Fortunately, there's help. The sendmail Cookbook provides step-by-step solutions for the administrator who needs to solve configuration problems fast. Say you need to configure sendmail to relay mail for your clients without creating an open relay that will be abused by spammers. A recipe in the Cookbook shows you how to do just that. No more wading through pages of dense documentation and tutorials and creating your own custom solution--just go directly to the recipe that addresses your specific problem. Each recipe in the sendmail Cookbook outlines a configuration problem, presents the configuration code that solves that problem, and then explains the code in detail. The discussion of the code is critical because it provides the insight you need to tweak the code for your own circumstances. The sendmail Cookbook begins with an overview of the configuration languages, offering a quick how-to for downloading and compiling the sendmail distribution. Next, you'll find a baseline configuration recipe upon which many of the subsequent configurations, or recipes, in the book are based.

Understanding the Linux Kernel (3rd Edition)

In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn't kept waiting any longer than necessary for the relatively slow disks.

The third edition of "Understanding the Linux Kernel" takes you on a guided tour of the most significant data structures, algorithms, and programming tricks used in the kernel. Probing beyond superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Important Intel-specific features are discussed. Relevant segments of code are dissected line by line. But the book covers more than just the functioning of the code; it explains the theoretical underpinnings of why Linux does things the way it does.

This edition of the book covers Version 2.6, which has seen significant changes to nearly every kernel subsystem, particularly in the areas of memory management and block devices.

Linux Thin Client Networks Design and Deployment

Written by an experienced Linux thin client network designer and implementer, this book for System Administrators covers the concepts of thin client networks and design issues for implementations of various sizes, followed by step-by-step HOW-TOs for all elements of implementing a thin client network based on open-source software. A thin, or lean client network is a client-server architecture where client computers depend primarily on a central server for processing activities. The thin clients focus on passing input to remote services and receiving and displaying the output; thin clients aren't as much about the hardware or software as about the design. With all the information you need to understand how the technology works, this book will help you evaluate how a Linux thin client network fits into your organization and make informed choices on the hardware and software needed to design and implement a stable work environment that meets the needs of your organization, large or small.

A Practical Guide to Ubuntu Linux

Ubuntu Linux is a state-of-the-art operating system, and you need a book that’s just as advanced. Along with being the most comprehensive reference to installing, configuring, and working with Ubuntu, A Practical Guide to Ubuntu Linux® also provides extensive server coverage you won’t find in any other Ubuntu book.

Best-selling author Mark Sobell begins by walking you through every feature and technique you need to know, from installing Ubuntu -- using the DVD included with the book -- to working with GNOME, Samba, exim4, Apache, DNS, NIS, firestarter, and iptables. Sobell’s exceptionally clear explanations demystify everything from system security to Windows file/printer sharing.

Sobell presents full chapters on using Ubuntu from the command line and GUI; thorough system administration and security guidance; and up-to-the-minute, step-by-step instructions for setting up networks and every major type of Internet server. Along the way, you’ll learn both the “hows” and the “whys” of Ubuntu. Sobell knows every Linux nook and cranny: He’s taught hundreds of thousands of readers and never forgets what it’s like to be new to Linux. Whether you’re a user, administrator, or programmer, this book gives you all you need -- and more.

Setting Up LAMP: Getting Linux, Apache, MySQL and PHP Working Together

You could think of Setting Up LAMP as four books in one, but it's actually something much more valuable: a single volume that presents the open-source technologies known collectively as LAMP—Linux, Apache, MySQL, and PHP—as tightly dovetailed components of today's most affordable and effective platform for building dynamic web-based applications.

Each technology has uses outside of this context, of course, but within it they form something greater than the sum of their parts. This book shows you how to take full advantage of this power, walking you through all the steps required to lay your Linux foundation, install and configure your Apache web server, and then begin using PHP to access content stored in MySQL.

Hacking Ubuntu: Serious Hacks Mods and Customizations

You can't "test quality into" a software product, but neither can you build a quality software product without test and analysis. Software test and analysis is increasingly recognized, in research and in industrial practice, as a core challenge in software engineering and computer science. Software Testing and Analysis: Process, Principles, and Techniques is the first book to present a range of complementary software test and analysis techniques in an integrated, coherent fashion. It covers a full spectrum of topics from basic principles and underlying theory to organizational and process issues in real-world application. The emphasis throughout is on selecting a complementary set of practical techniques to achieve an acceptable level of quality at an acceptable cost.
