While Mac OS X garners all the praise from pundits, and Windows XP attracts all the viruses, Linux is quietly being installed on millions of desktops every year. For programmers and system administrators, business users, and educators, desktop Linux is a breath of fresh air and a needed alternative to other operating systems.

The "Linux Desktop Pocket Guide" is your introduction to using Linux on five of the most popular distributions: Fedora, Gentoo, Mandriva, SUSE, and Ubuntu. Despite what you may have heard, using Linux is not all that hard. Firefox and Konqueror can handle all your web browsing needs; GAIM and Kopete allow you to chat with your friends on the AOL, MSN, and Yahoo! networks; and the email programs Evolution and Kontact provide the same functionality as Microsoft Outlook, with none of the cost. All of these programs run within the beautiful, feature-packed, and easy-to-use GNOME or KDE desktop environments.

No operating system truly "just works," and Linux is no exception. Although Linux is capable of running on most any computing hardware that Microsoft Windows can use, you sometimes need to tweak it just a little to make it work the way you really want. To help you with this task, "Linux Desktop Pocket Guide" covers essential topics, such as configuring your video card, screen resolution, sound, and wireless networking. And laptop users are not left out--an entire section is devoted to the laptop issues of battery life, sleep, and hibernate modes.

FreeBSD and OpenBSD are increasingly gaining traction in educational institutions, non-profits, and corporations worldwide because they provide significant security advantages over Linux. Although a lot can be said for the robustness, clean organization, and stability of the BSD operating systems, security is one of the main reasons system administrators use these two platforms.

There are plenty of books to help you get a FreeBSD or OpenBSD system off the ground, and all of them touch on security to some extent, usually dedicating a chapter to the subject. But, as security is commonly named as the key concern for today's system administrators, a single chapter on the subject can't provide the depth of information you need to keep your systems secure.

FreeBSD and OpenBSD are rife with security "building blocks" that you can put to use, and "Mastering FreeBSD and OpenBSD Security" shows you how. Both operating systems have kernel options and filesystem features that go well beyond traditional Unix permissions and controls. This power and flexibility is valuable, but the colossal range of possibilities need to be tackled one step at a time. This book walks you through the installation of a hardened operating system, the installation and configuration of critical services, and ongoing maintenance of your FreeBSD and OpenBSD systems.

Using an application-specific approach that builds on your existing knowledge, the book provides sound technical information on FreeBSD and Open-BSD security with plenty of real-world examples to help you configure and deploy a secure system. By imparting a solid technical foundation as well as practical know-how, it enables administrators to push their server's security to the next level. Even administrators in other environments--like Linux and Solaris--can find useful paradigms to emulate.

Written by security professionals with two decades of operating system experience, "Mastering FreeBSD and OpenBSD Security" features broad and deep explanations of how how to secure your most critical systems. Where other books on BSD systems help you achieve functionality, this book will help you more thoroughly secure your deployments.

With the release of Windows XP Service Pack 2 (SP2), Microsoft latest and most reliable corporate desktop operating system now provides better protection against viruses, worms, and malicious hackers. SP2 includes Windows Firewall, Pop-up Blocker for Internet Explorer, and the new Windows Security Center. But it still comes without a single page of printed instructions.

This superbly written guide fills the gap. Coauthored by David Pogue, "New York Times" technology columnist and Missing Manuals creator, "Windows XP Pro: The Missing Manual" uses wit, technical insight, and scrupulous objectivity to light the way for first-time and intermediate network and standalone PC users. In fact, this jargon-free book explains XP's features so clearly revealing which work well and which don't that it should have been in the box in the first place.

The book reveals which features work well and which don't, such as the Remote Desktop software that enables people to connect to the office from home, the encryption file system that protects sensitive information, and the Windows Messenger that enables real-time text, voice and video communication. Contents include:

Getting started. The book's early chapters cover using menus, finding lost files, reducing window clutter, and taming the new, multi-column Start menu.

Mastering the network. Special chapters help you navigate the corporate network, dial in from the road, and even set up your own small-office (peer-to-peer) network, step by step.

Understanding security. User accounts, file encryption, and the NTFS file system keep your private files private, while still offering network access to coworkers you specify.

Flying the Net.This book demystifies Outlook Express 6 for email, Internet Explorer 6 for Web browsing, and the new Windows Messenger for voice, chat, and video conferencing.

"Windows XP Pro: The Missing Manual" isn't for system administrators or OS theory geeks; it's for the novice or budding power user who wants to master the machine and get down to work. Yet, anyone who uses XP Pro (including hardcore techies) will find this new system much easier-- and more fun--to digest with this new Missing Manual.

If you're seeking ways to build network-based applications or XML-based web services, Microsoft provides most of the tools you'll need. XML is integrated into the .NET Framework and Visual Studio .NET, but if you want to get a grasp on how .NET and XML actually work together, that's a different story. With ."NET & XML," you can get under the hood to see how the .NET Framework implements XML, giving you the skills to write understandable XML-based code that interoperates with code written with other tools, and even other languages.

."NET & XML" starts by introducing XML and the .NET Framework, and then teaches you how to read and write XML before moving on to complex methods for manipulating, navigating, transforming, and constraining it. To demonstrate the power of XML in .NET, author Niel Bornstein builds a simple hardware store inventory system throughout the book. As you move from chapter to chapter, you'll absorb increasingly complex information until you have enough knowledge to successfully program your own XML-based applications. This tutorial also contains a quick reference to the API, plus appendices present additional .NET assemblies that you can use to work with XML, and how to work with the .NET XML configuration file format.

One study puts the potential market for new software based on XML at or near $100 billion over the next five years. The .NET Framework gives you a way to become a part of it. But to use XML and .NET effectively, you need to understand how these two technologies work together. This book gives you the insight to take full advantage of the power the two provide.

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. Recipes in the following chapters stand on their own and offer solutions for properly configuring important sendmail functions such as:

Delivering and forwarding mail

Relaying

Masquerading

Routing mail

Controlling spam

Strong authentication

Securing the mail transport

Managing the queue

Securing sendmail

"sendmail Cookbook" is more than just a new approach to discussing sendmail configuration. The book also provides lots of new material that doesn't get much coverage elsewhere--STARTTLS and AUTH are given entire chapters, and LDAP is covered in recipes throughout the book. But most of all, this book is about saving time--something that most system administrators have in short supply. Pick up the "sendmail Cookbook" and say good-bye to sendmail dread.

Fully updated for version 1.1 of the .NET Framework, .NET Framework Essentials, 3rd Edition is an objective, concise, no-nonsense overview of the Microsoft .NET Framework for developing web applications and services.

With the spread of web-enabled desktop clients and web-server based applications, developers can no longer afford to treat security as an afterthought. It's one topic, in fact, that .NET forces you to address, since Microsoft has placed security-related features at the core of the .NET Framework. Yet, because a developer's carelessness or lack of experience can still allow a program to be used in an unintended way, Programming .NET Security shows you how the various tools will help you write secure applications.

There is a rapid growth of automation in server rooms and data centers. The days of having many administrators running around busily configuring and maintaining servers are gone and have been replaced with droves of Salt-Minions; agents beavering away on the target nodes ensuring the configuration is as specified. This book covers Salt Open (also known as SaltStack Open) from the ground up and shows you how to work with two Linux distributions. You'll see how Salt Open is duplicated with ArubaOS and IOS networking devices, which can be configured without the underlying OS. As you step through the configuration options, you'll learn how to run remote execution modules from the CLI before looking at stateful configuration using SLS files. Moving on, you'll learn how to configure the systems where you also need to monitor your devices and that is when reactors and beacons come into play. Creating beacons to alert the server when thresholds are exceeded, you will be able to create reactors to mitigate the issues identified by the beacons. By the end of this book, you will be able to deploy Salt to your servers and network infrastructure. You will be able to install the Salt-Master and Salt-Minion, executing commands from both the Master and the Minion. The networking devices you need to manage will be controlled through the Salt_Proxy Minions that you have configured. Finally, you will be able to load-balance connections to the master with Salt-Syndic. What You'll Learn Install Salt Services on Ubuntu and CentOS based systems Work with remote execution modules Format YAML files correctly Provide defined configuration using state files Use Salt-Proxy to configure network devices Automate the configuration of Linux servers and networking devices Add value for both the server and network automation team Who This Book Is For System administrators experienced in Linux administration, who desire to expand their horizons into the world of automation, moving from scripts to states.

Develop UI-heavy applications more easily, faster, and error-free. Based on several enhancements to the Swift language, SwiftUI takes a declarative approach to building UIs. Instead of imperatively coding the UI, this book will show you how to describe how you want your UI to look. SwiftUI treats the UI as a function of its state, thereby making managing your app's state a lot easier. Change the underlying data model to redraw all parts of the UI that are connected to that particular slice of data. Likewise, easily update the underlying data model from the UI elements your data model is connected to. Combine is Apple's Functional Reactive Programming framework. It complements SwiftUI and other frameworks, such as the networking APIs, in a natural way. Using Combine, you can subscribe to events and describe data processing in a way that is free of side effects. This allows for an easier implementation of event-driven applications. Using SwiftUI and Combine build more error-free apps in a shorter amount of time, targeting all of Apple's platforms (iOS, iPadOS, watchOS, macOS, tvOS) with little to no overhead. By the end of the book you will have a solid understanding for architecting and implementing UI-heavy apps in a declarative and functional reactive way using SwiftUI, Combine, and async/await. You will: - Build simple and gradually more complex UIs in SwiftUI - Understand SwiftUI's state management system - Work with Combine and Swift's new async/await APIs to access the network and access other asynchronous APIs - Architect and structure modern applications on Apple platforms using SwiftUI, Combine, and async/await

DHCP for Windows 2000 is custom-designed for system administrators who are responsible for configuring and maintaining networks with Windows 2000 servers.
