Chapter 3. Filtering Our Way in Wireshark

This chapter will assist you in identifying and applying the usage of Wireshark filters—namely, the capture and display filters. Filtering provides a powerful way to capture or see traffic; it is an effective way to segregate the desired traffic stream from noise (traffic ). The following are the topics we will cover in this chapter:

  • Introducing capture filters
  • Why and how to use capture filters
  • Introducing display filters
  • Why and how to use display filters
  • Colorizing traffic

Let's start our analyzer and apply some filters to understand the usage and effectiveness of them. We will take a step-by-step walk through the process of creating display and capture filters. Also, we will find utility, which is quite effective when troubleshooting network issues.
