    Abstract:

    Publisher Summary This chapter discusses the major components of the Wireshark GUI. It also explains the major functionality of the Wireshark application, and the ways to access it. Network captures, open saved network captures, and print captures can now be performed. The user should also be equipped to use display filters to filter the packets displayed in the Summary window, color the packets in the Summary window for easier readability, or find a packet in the capture with particular characteristics. The chapter highlights the ways to navigate the protocol tree in the Protocol Tree window–– to examine the contents of a packet, and to use the Protocol Tree fields–– to prepare new display filter strings. It also explains enabling, and disabling decoding of particular protocols, and gives understanding of the usage of some of the commonly used tools in Wireshark to gain better visibility into TCP Streams.

  • Chapter 4 - Using Wireshark
    Wireshark & Ethereal Network Protocol Analyzer Toolkit, 2006
    Co-Authors: Angela Orebaugh, Josh Burke, Larry Pesce, Gilbert Ramirez, Joshua Wright, Greg Morris
    Abstract:

    Publisher Summary Wireshark provides insight into a computer network, which is useful when implementing protocols, debugging network applications, testing networks, and debugging live networks. Being able to see and analyze network traffic is very instructive. This chapter discusses the main components of the Wireshark Graphical User Interface (GUI), including main window, menu bar, tool bar, summary window, protocol tree window, data view window, filter bar, information field, and display information. The Summary window displays a summary of each packet (one per line) in a capture. One or more columns of summary data are displayed for each packet. The Protocol Tree window helps in examining the tree created by Wireshark from decoding a packet. The chapter also discusses the context-sensitive pop-up windows available in the Summary window, the Protocol Tree window, and the Data View window along with the various dialog boxes that are launched by the menus and toolbars. It shows how to perform basic tasks in Wireshark (e.g., capturing network traffic, loading and saving capture files, performing basic filtering, printing packets) using the advanced tools provided by Wireshark. Several command-line options supported by the Wireshark are also documented in the chapter.
