Wireshark Network Analysis

The Official Wireshark Certified Network Analyst (WCNA) Study Guide

Wireshark is the world's most popular network analyzer tool with over 1 million downloads per month. This book provides insider tips and tricks to spot performance issues fast - no more finger pointing because the packets never lie! From "Death by Database" to "Troubleshooting Time Syncing," 49 case studies offer insight into performance and security situations solved with Wireshark. Learn to customize Wireshark for faster and more accurate analysis of your network traffic. Build graphs to identify and expose issues such as packet loss, receiver congestion, slow server response, network queuing and more. 

This book is the Official Study Guide for the WCNA Certification (formerly known as the Wireshark Certified Network Analyst certification). This Second Edition includes an introduction to IPv6, ICMPv6 and DHCPv6 analysis, updated Wireshark functionality and new trace files.

Who is this book for?

This book offers an ideal reference for information technologists responsible for key network tasks including:

  • identifying poor network performance due to high path latency 

  • locating internetwork devices that drop packets 

  • validating optimal configuration of network hosts 

  • analyzing application functionality and dependencies 

  • optimizing application behavior for best performance 

  • knowing how TCP/IP networks function 

  • analyzing network capacity before application launch 

  • verifying application security during launch, log in and data transfer 

  • identifying unusual network traffic indicating potentially compromised hosts 

  • studying for the Wireshark Certified Network Analyst (WCNA) Exam - now called the "WCNA Certification Exam"

"The book provides a solid foundational level of instruction on how to use Wireshark to conduct packet analysis at the data link, network, transport, and application protocol layers."

Errata

As of Wireshark v3, you can now use dhcp as a display filter instead of bootp! Yay!

As of Wireshark v3, you can now use tls as a display filter instead of ssl. Both will work for a while, but if the traffic is TLS, use tls.

Last-minute changes to Wireshark 1.8.0 (and later) File menu item: use File | Export Specified Packets and File | Export Packet Dissections in place of File | Save As. This change affects Figure 20, Figure 23, and pages 45, 188, 193, 316, 665, 692.

The File | Export options are listed directly on the main File Menu drop down list. For example, rather than using File | Export | Objects | HTTP, you now use File | Export Objects | HTTP (one level was removed). This change affects pages 287, 289, 290, 311, 313, 320, 558, 574, 576, 860.

[Bug Fixed Now] Lab 10 and Wireshark Bug: In Lab 10 you are instructed to create File Sets. Unfortunately, we've found that the 32-bit version Wireshark 1.10.x won't create more than a single file. You must use the 64-bit version of Wireshark 1.10.x or regress back to 1.8.x. Unfortunately, this bug still shows up in the 32-bit version of Wireshark 1.11.3.
