Summary

In this chapter, we were able to successfully diagnose multiple issues with this server. Initially, the service was not running. Then, the service was being blocked by the Windows Firewall. Then, there were incorrect credentials provided to the client. Furthermore, using Wireshark we were able to diagnose and provide some information as to where we needed to look, whether it was on the client side or the server side, or in between, and it was a great help, allowing us to resolve this issue quickly. In this chapter, we talked about Wireshark plugins, using Lua and creating dissectors. We then evaluated a troubleshooting scenario, determining where to create our captures, capturing the traffic, and doing some basic diagnostics, and then diving into it a little bit more and actually reading the FTP packets, once they started to send and receive to the client. We have now reached the end of the book. I hope you have enjoyed reading it.
