Analyzing network packets


Those of you that think of yourself as a hacker, do you know what does a network packet look like?  Have you ever read network packets in your life, do you know how they work?  Take a look in the TCP packet below and try to figure out what the packet is doing as well as getting the source ip address and port of the sender.
