So in this chapter, you've learned about some email analysis using POP and SMTP. We also looked at 802.11, which is wireless, what certain things look like in a packet capture, and the fact that you'll need to do additional troubleshooting outside of what you can do in Wireshark in order to properly diagnose wireless. We also looked at VoIP analysis using SIP and RTP, creating that connection and then transmitting that audio data directly from one device to another. Then, we also played that back using the built-in tools in Wireshark, and manipulated some of the settings in that for jitter, in order to recreate problems and be able to listen to what that sounds like.
Next is Chapter 10, Command-Line Tools, where we'll use some command-line tools to extend Wireshark, and talk about some of the enhancements that you can add to it.
