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.

[code]
00 1c f0 39 8e 45 00 1c  f0 8a a1 71 08 00 45 00
00 34 06 6e 40 00 80 06  9a 0e c0 a8 01 02 45 a2
52 fb c0 a7 00 50 a1 f6  7c bb 00 00 00 00 80 02
20 00 15 25 00 00 02 04  05 b4 01 03 03 02 01 01
04 02
[/code]

Tips: Think of the packet as an Ethernet frame.
