Mastering Wireshark 2

By: Andrew Crouthamel

Overview of this book

Wireshark, a combination of a Linux distro (Kali) and an open source security framework (Metasploit), is a popular and powerful tool. Wireshark is mainly used to analyze the bits and bytes that flow through a network. It efficiently deals with the second to the seventh layer of network protocols, and the analysis made is presented in a form that can be easily read by people. Mastering Wireshark 2 helps you gain expertise in securing your network. We start with installing and setting up Wireshark2.0, and then explore its interface in order to understand all of its functionalities. As you progress through the chapters, you will discover different ways to create, use, capture, and display filters. By halfway through the book, you will have mastered Wireshark features, analyzed different layers of the network protocol, and searched for anomalies. You’ll learn about plugins and APIs in depth. Finally, the book focuses on pocket analysis for security tasks, command-line utilities, and tools that manage trace files. By the end of the book, you'll have learned how to use Wireshark for network security analysis and configured it for troubleshooting purposes.

So we'll browse again to where Wireshark lives, and we'll do a directory listing. We'll see that we have tshark.exe. This is installed by default with Wireshark. In order to run tshark, all you have to do is, of course, run tshark.exe. If you do so, it automatically begins capturing on your default interface:

You'll notice that it shows the packets that it's capturing directly to the command-line interface, directly to stdout. It does so because it does not have a graphical interface; there's nothing for it to display except for the screen that it's currently using, which is the command interface. You...
