Red Hat Linux is the most popular distribution of Linux currently in use. Red Hat Linux has shown itself to be a robust, reliable operating system that can run on a variety of hardware, from personal computers to large mainframes. Linux in general, and Red Hat Linux in particular, is a very powerful operating system that can be used at the enterprise level as a full-fledged server, as well as at the workstation level for typical user applications. For those of us dissatisfied with the reliability of other commercially available operating systems, Red Hat Linux is a pleasant alternative. This book is divided into five parts. Each part covers a specific area of functionality in a typical Red Hat Linux system.

Mark Twain once wrote, “Writing is easy. All you have to do is cross out the wrong words.” So we have done the easy part for you. We crossed out all the wrong words and came up with this book. What are left are the words that will help you plan for, install, acquire, protect, manage, and administer wireless networks from personal area to wide area. We have started your journey by providing information on:
If you’ve installed some level of wireless capability in your home and want to take it to the next level, or are thinking of purchasing a wireless computer network and want a high-powered setup from the get-go, this is the book for you. Here’s the bottom line: If you want to (or have) cut the cord, we want to help you improve your network. If you have a wireless network, you have probably realized that performance can vary wildly around your home. What’s more, you might be trying to add additional gear onto your network, only to find it does not seem to solve the problems you set out to fix. You’re not alone — many of those who have mastered the first stage of getting a wireless network up and running have wondered how they can simply get more out of it. Towards that end, this book helps you get the most out of your network over the long term. With this book in hand, you’ll have all the information that you need to know about the following topics:
If you’re thinking of purchasing a wireless computer network and installing it in your home, this is the book for you.

With this book in hand, you’ll have all the information that you need to know about the following topics (and more):

This book is a general-purpose guide to all things that have to do with the Internet. It takes on a variety of subjects — how to send and receive e-mail, chat online, conduct Internet research, use Yahoo!, shop on eBay, enjoy music with iTunes, and create your own Web pages. Don’t look in this book to find out how the Internet works. Look here to find out how you can make the most of the time that you spend on the Internet.
These are exciting times for the Internet. Peer-to-peer file sharing, news aggregators, and other advances in technology have inspired a new generation of Web sites and services. Never before have this many Web sites and services been available on the Internet. The idea behind this book is to present everything on the Internet that’s worth doing because it’s useful, it’s a lot of fun, or it’s innovative and therefore worth checking out. Close to a thousand different Web sites are described in this book, but this book isn’t a directory of Web sites on the Internet. The focus is on doing things — researching, online banking, communicating, making new friends, playing games, talking over the Internet telephone, online shopping, online selling, and blogging. In the course of describing these and other activities — everyday activities that can be part of your Internet repertoire — I introduce you to the Internet’s best Web sites and services.
This isn’t the kind of book you pick up and read from start to finish, as if it were a cheap novel. If I ever see you reading it at the beach, I’ll kick sand in your face. This book is more like a reference, the kind of book you can pick up, turn to just about any page, and start reading. It has 30 chapters, each one covering a specific aspect of networking — such as printing on the network, hooking up network cables, or setting up security so that bad guys can’t break in. Just turn to the chapter you’re interested in and start reading. Each chapter is divided into self-contained chunks, all related to the major theme of the chapter. For example, the chapter on hooking up the network cable contains nuggets like these:
Networking All-in-One Desk Reference For Dummies, 2nd Edition, is intended to be a reference for all the great things (and maybe a few not-so-great things) that you may need to know when you’re setting up and managing a network. You can, of course, buy a huge 1,000-page book on each of the networking topics covered in this book. But then, who would you get to carry them home from the bookstore for you? And where would you find the shelf space to store them? In this book, you get the information you need all conveniently packaged for you in between one set of covers. This book doesn’t pretend to be a comprehensive reference for every detail of these topics. Instead, this book shows you how to get up and running fast so that you have more time to do the things you really want to do. Designed using the easy-to-follow For Dummies format, this book helps you get the information you need without laboring to find it. Networking All-in-One Desk Reference For Dummies, 2nd Edition, is a big book made up of several smaller books — minibooks, if you will. Each of these minibooks covers the basics of one key element of network management, such as setting up network hardware, installing a network operating system, or troubleshooting network problems. Whenever one big thing is made up of several smaller things, confusion is always a possibility. That’s why Networking All-in-One Desk Reference For Dummies, 2nd Edition, is designed to have multiple access points (I hear an acronym coming on — MAP!) to help you find what you want. At the beginning of the book is a detailed table of contents that covers the entire book. Then, each minibook begins with a minitable of contents that shows you at a glance what chapters are included in that minibook. Useful running heads appear at the top of each page to point out the topic discussed on that page. And handy thumb tabs run down the side of the pages to help you quickly find each minibook. Finally, a comprehensive index lets you find information anywhere in the entire book. This isn’t the kind of book you pick up and read from start to finish, as if it were a cheap novel. If I ever see you reading it at the beach, I’ll kick sand in your face. This book is more like a reference, the kind of book you can pick up, turn to just about any page, and start reading. You don’t have to memorize anything in this book. It’s a “need-to-know” book: You pick it up when you need to know something. Need to know how to set up a DHCP server in Windows? Pick up the book. Need to know how to create a user account in Linux? Pick up the book. Otherwise, put it down and get on with your life.
Welcome to Hacking For Dummies. This book outlines computer hacker tricks and techniques — in plain English — to assess the security of your own information systems, find security vulnerabilities, and fix the vulnerabilities before malicious and criminal hackers have an opportunity to take advantage of them. This hacking is the professional, aboveboard, and legal type of security testing — which I call ethical hacking throughout the book. Computer and network security is a complex subject and an evermoving target. You must stay on top of it to ensure your information is protected from the bad guys. You can implement all the security technologies and other best practices possible, and your information systems may be secure — as far as you know. However, until you understand how hackers think and apply that knowledge to assess your systems from a hacker’s-eye view, you can’t get a true sense of how secure your information really is. Ethical hacking — sometimes referred to as penetration testing or white-hat hacking — is a necessary requirement to ensure that information systems are truly secure on an ongoing basis. This book provides you with the knowledge required to successfully implement an ethical hacking program, along with countermeasures that you can implement to keep malicious hackers out of your business.
