Those of you who run networks on Windows 2000 know the benefits of using Active Directory for managing user information and permissions. You also know what a bear it can be. The newer version included with Windows Server 2003 has over 100 new and updated features to simplify deployment, but once it's in place many system administrators still find Active Directory challenging. If you're among those looking for practical hands-on support, help is here with our new Active Directory Cookbook for Windows Server 2003 & Windows 2000, a unique problem-solving guide that offers quick answers for both versions of the directory. The book contains hundreds of step-by-step solutions for both common and uncommon problems that you might encounter with Active Directory on a daily basis--including recipes to deal with the Lightweight Directory Access Protocol (LDAP), multi-master replication, Domain Name System (DNS), Group Policy, the Active Directory Schema, and many other features. Author Robbie Allen, a Senior Systems Architect at Cisco Systems and co-author of our Active Directory tutorial, based this collection of troubleshooting recipes on his own experience, along with input from Windows administrators throughout the industry. Each recipe includes a discussion to explain how and why the solution works, so you can adapt the problem-solving techniques to similar situations.

Windows XP users and administrators need a quick and easy way to find answers. Plenty of books go into detail about the theory behind a particular technology or application, but few go straight to the essentials for getting the job done. Windows XP Cookbook does just that, tackling the most common tasks needed to install, manage, and support Windows XP.

Из чего состоит дистрибутив Linux? Как он работает и почему? Что умеет, и как этими умениями управлять? Кто они такие, эти таинственные «линуксо- иды»? пингвины? Если писать программы, то про что их писать? И вообще— что на самом деле такое: «Linux», «Дистрибутив», «Сообщество», «Свободные программы» наконец? Обо всём этом и о некотором другом и написано во второй половине нашей книги. Раз уж приходится управлять таким сложным созданием, как пингвин, и тем более—таким сложным инструментом, как компьютер, без знаний не обойтись. Если вы не считаете поведение компьютера «предопределением природы», и хотите что-то изменить к лучшему, непременно стоит познакомиться с тем, что именно вы хотите изменить. По крайней мере, мы—разработчики дистрибутивов ALT Linux и участники Linux-сообщества—для себя решили начинать именно со знаний.

Whether you need a network of ten Linux PCs and a server or a datacenter with a few thousand Unix nodes, you need to know how to automate much of the installation, configuration, and standard system administration. Build your network once using cfengine, and the network build will work, without user intervention, on any hardware you prefer.Automating Linux and Unix System Administration, Second Editionis unique in its focus on how to make the system administrator's job easier and more efficient: instead of just managing the system administrator's time, the book explains the technology to automate repetitive tasks and the methodology to automate successfully. Both new and seasoned professionals will profit from industry–leading insights into the automation process. System administrators will attain a thorough grasp of cfengine, kickstart, and shell scripting for automation. After reading all chapters and following all exercises in this book, the reader will be able to set up anything from a Linux datacenter to a small office network. What you'll learn See how to make changes on many UNIX and Linux hosts at once in a reliable and repeatable manner. Learn how to automate things correctly so you only have to do it once, by leveraging the authors' experience in setting up small, medium, and large networks. Set up a Linux datacenter or a network correctly. Explore handling real–world environments where not all hosts are configured alike via a case study of a fictional new datacenter buildout. Examine real–world examples for core infrastructure services (DNS, mail, monitoring, log analysis, security, cfengine, imaging) to build on in your environment. Understand core system administration best practices, which are a key part of how cfengine and automations deployments are outlined in the book. Learn how to make changes reversible, repeatable, and correct the first time through interaction with product/application stakeholders (programmers, product managers, customers, etc.). Who this book is for This book is for Linux system administrators who want to learn about the software and methodology to automate repetitive tasks-regardless of network or datacenter size-in one place.

The first comprehensive, expert guide for end-to-end Linux application optimization Learn to choose the right tools—and use them together to solve real problems in real production environmentsSuperior application performance is more crucial than ever—and in today's complex production environments, it's tougher to ensure, too. If you use Linux, you have extraordinary advantages: complete source code access, plus an exceptional array of optimization tools. But the tools are scattered across the Internet. Many are poorly documented. And few experts know how to use them together to solve real problems. Now, one of those experts has written the definitive Linux tuning primer for every professional: Optimizing Linux® Performance.Renowned Linux benchmarking specialist Phillip Ezolt introduces each of today's most important Linux optimization tools, showing how they fit into a proven methodology for perfecting overall application performance. Using realistic examples, Ezolt shows developers how to pinpoint exact lines of source code that are impacting performance. He teaches sysadmins and application developers how to rapidly drill down to specific bottlenecks, so they can implement solutions more quickly. You'll discover how to: Identify bottlenecks even if you're not familiar with the underlying system Find and choose the right performance tools for any problem Recognize the meaning of the events you're measuring Optimize system CPU, user CPU, memory, network I/O, and disk I/O—and understand their interrelationships Fix CPU-bound, latency-sensitive, and I/O-bound applications, through case studies you can easily adapt to your own environmentInstall and use oprofile, the advanced systemwide profiler for Linux systemsIf you're new to tuning, Ezolt gives you a clear and practical introduction to all the principles and strategies you'll need. If you're migrating to Linux, you'll quickly master Linux equivalents to the tools and techniques you already know. Whatever your background or environment, this book can help you improve the performance of all your Linux applications—increasing business value and user satisfaction at the same time.
