Networking All-in-One Desk Reference

About This Book

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.

How This Book Is Organized

Each of the nine minibooks contained in Networking All-in-One Desk Reference For Dummies, 2nd Edition, can stand by themselves. The first minibook covers the networking basics that you should know to help you understand the rest of the stuff in this book. Of course, if you’ve been managing a network for awhile already, you probably know all this stuff, so you can probably skip Book I or just skim it over quickly for laughs. The remaining minibooks cover a variety of networking topics that you would normally find covered in sepa­rate books. Here is a brief description of what you find in each minibook.

Book I: Networking Basics

This minibook covers the networking basics that you need to understand to get going. You find out what a network is, how networking standards work, what hardware components are required to make up a network, and what net­work operating systems do. You discover the difference between peer-to-peer networking and client-server networking. And you also get a comparison of the most popular network operating systems, including Windows NT Server, Windows 2000 Server, Windows Server 2003, Novell’s NetWare, and Linux.

Book II: Building a Network

In this minibook, you find out the ins and outs of building a network. First, you see how to create a plan for your network. After all, planning is the first step of any great endeavor. Then, you discover how to install network hard­ware such as network interface cards and how to work with various types of networking cable. You receive some general pointers about installing a network server operating system. And finally, you gain insight into how to configure various versions of Windows to access a network.

Book III: Network Administration and Security

In this minibook, you discover what it means to be a network administrator, with an emphasis on how to secure your network so that it’s safe from intrud­ers, but at the same time allows your network’s users access to everything they need. In the real world, this responsibility isn’t as easy as it sounds. This minibook begins with an overview of what network administrators do. Then, it describes some of the basic practices of good network security, such as using strong passwords and providing physical security for your servers. Then, it presents an overview of setting up network user accounts. And it concludes with some additional security techniques, such as using virus scanners and setting up firewalls.

Book IV: Network Troubleshooting and Disaster Planning

When something goes wrong with your network, you can turn to this mini-book for guidance on isolating the problem and determining how to correct it. This minibook covers not only major network problems (“my network’s dead,”) but also those insidious performance problems (“I can get to the server, but it’s ess-el-oh-double-ewe”). And you find help for one of the most common network complaints: e-mail that doesn’t get through.

Before something goes wrong with your network, I hope you turn to this minibook for guidance on how to protect your network through a good, comprehensive backup scheme, and how to create a disaster recovery plan (known now by the trendy term, Business Continuity Planning).

Book V: TCP/IP and the Internet

This minibook is devoted to the most popular network technology on the planet: TCP/IP. (Actually, it may be the most popular protocol in the universe.

The aliens in Independence Day had a TCP/IP network on their spaceship, enabling Will Smith and Jeff Goldblum to hack their way in. The aliens should have read the section on firewalls in Book III.)

In this minibook, you discover the various protocols that make up the entire TCP/IP suite. You find out all about IP addresses, subnetting, routing, and all that good stuff. You encounter DHCP and DNS. And you discover how to use those handy TCP/IP troubleshooting tools like Ping and Tracert.

Book VI: Home Networking

This minibook covers the information you need to know to install a network at home. You discover how to set up a basic Windows network, the various options for networking your home (including wireless, phone networks, and PowerLine networks), and how to incorporate other gadgets into your net­work. You also find out about VoIP, which lets you replace your telephone service with Internet-based phone service.

Book VII: Wireless Networking

In this minibook, you discover the ins and outs of setting up and securing a wireless network.

Book VIII: Windows Server 2003 Reference

Plus, you find a handy reference to the many Windows networking commands that you can use from a command prompt.
