Overview of this book

Wireshark is a popular and powerful packet analysis tool that helps network administrators investigate latency issues and potential attacks. Over the years, there have been many enhancements to Wireshark’s functionality. This book will guide you through essential features so you can capture, display, and filter data with ease. In addition to this, you’ll gain valuable tips on lesser-known configuration options, which will allow you to complete your analysis in an environment customized to suit your needs. This updated second edition of Learn Wireshark starts by outlining the benefits of traffic analysis. You’ll discover the process of installing Wireshark and become more familiar with the interface. Next, you’ll focus on the Internet Suite and then explore deep packet analysis of common protocols such as DNS, DHCP, HTTP, and ARP. The book also guides you through working with the expert system to detect network latency issues, create I/O and stream graphs, subset traffic, and save and export captures. Finally, you’ll understand how to share captures using CloudShark, a browser-based solution for analyzing packet captures. By the end of this Wireshark book, you’ll have the skills and hands-on experience you need to conduct deep packet analysis of common protocols and network troubleshooting as well as identify security issues.

Personalizing the layout

Although Wireshark is functional in default mode, it's easy to modify appearance and layout to optimize your workflow. In addition to personalizing layout and general appearance, you can modify many other components. For example, you can change the language, customize the number of icons, recent filters, and folders, and define what you want to appear in the status bar. Let's start with how you can customize the appearance.

Altering the appearance

In Wireshark, you can tailor the general appearance in the following ways:

  • Identify the default location to open files.
  • List how many display filters to show.
  • Define how you want the main toolbar to appear.

To view all the choices where you can make and modify your selections, go to Edit and then Preferences, which will bring up a dialog box. Once there, expand Appearance, as shown in the following screenshot:
