I am always looking for quick reference guides that can make me look like a genius. I ran across the the cheat sheets that packetlife.net offers on their site. I am completely blown away by them. They spent allot of time creating cheat sheets on everything from wireshark captures to IPv4 subnetting. Even though allot us know some of the information on these sheets its nice to have something directly at our fingertips. So go over and print these cheat sheets up and post next to your computer. I promise you it will be well worth time!
