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."

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.
