Introduction to Network Analysis Second Edition ML-B103-1 Introduction to Network Analysis (Second Edition) The revised/updated analysis manual by Laura Chappell. This version dumps the LANalyzer for Windows screens and functionality and focuses on EtherPeek and Sniffer Pro throughout. Also in this edition: full-duplex analysis, frame and field offsets, and a whole bunch of new trace files. Each chapter ends with a test to determine your comprehension level. The answers can be found in Appendix A.

Appendix A, "Answers to the Chapter Tests" Covers the various elements of a network analyzer and provides instructions on tapping into hubbed, switched, Provides the answers to all the questions posed at the or routed networks. In this section, you'll find out how end of the Chapters. standalone analyzers differ from distributed analyzers as well as the differences between software and hardware- based solutions. Appendix B, "The Basics of Data Flows" Is a 'must read' for anyone who wants to troubleshoot or Chapter 2, "How Do You Start?" optimize network communications. It provides the foundation of knowledge on how packets are hubbed, Walks you through the entire process of tapping in, switched and routed through a network. It covers what obtaining a network overview (the 'Laying on of Hands'), these interconnecting devices can and cannot do to the classifying traffic and trends, identifying hot spots and packet contents. You should know the materials in documenting your findings. You'll learn how to read the Appendix B inside and out. summary window and detailed packet decodes. I’ll introduce my favorite analyzers -- EtherPeek and Sniffer Pro. Finally, this chapter gives you a list of seven analysis Appendix C, "Resources and References" tasks you can do today on your network. Lists supplemental materials that can help you with your network analysis focus. Many of the materials were Chapter 3, “Packet Formats and Decodes” written by me (there seems to be a shortage of packet- level documentation these days). Takes you into the packet structures and communication sequences often seen on a network. In this chapter, we’ll There are additional references and resources online at look the headers that are built to get packets from the www.packet-level.com. application through the protocol stack and onto the network. Specifically, we’ll examine Ethernet and Token Ring headers. This chapter also provides field offset and details for IP, TCP and UDP headers. Finally, we’ll follow a typical communication to see how the data flows. Chapter 4, "Identifying Typical Problems" Focuses on the most common errors that occur on Ethernet, Token Ring, IPX/SPX and TCP/IP networks. After a brief overview of the communications processes used by each network type, you are introduced to the types of problems that you should watch for. Throughout this chapter, you are provided with extra links to areas that contain more depth of information… for those of you who just can't get enough. Chapter 5, “Analysis Tools and Exercises” Gives you an idea of the other tools that I use to analyze communications. These tools include my beloved NetScanTools Pro, PacketScrubber to sanitize packets, ProConvert to convert trace files between various analyzer versions, EtherPeek for Windows and Sam Spade. Of course, a good quality blender is also required to make the perfect Margarita!
