Technical requirements
In this chapter, we'll capture packets. The initial setup and packet capturing use a physical switch that you may not have access to. However, once we start looking at the packets themselves, all of the capture files are available for download. Since the majority of this chapter is about analyzing and interpreting the captured packets, our existing Linux host should do nicely without undue modification. This is also a good way for us to ensure that when you are following the examples in this chapter, your display matches what we're describing.
Do feel free to build packet capturing into your lab, though, or better yet into your work environment. It's an extremely valuable tool in troubleshooting or just to get a better understanding of the various protocols and applications that we use every day!
The capture files that are referenced in this chapter can be found in the C11 folder of this book's GitHub repository: https://github.com/PacktPublishing...
