There's a site I check out every now and then called Packet Life.

The guy has far too much time and has used Visio to create a bunch of Cisco Cheat Sheets for various protocols/apps/tech.

His blog has alot of useful stuff in it too.

Optus Supplied me a program that incorporates a TFTP server all I do is enter a few details, plug it in via lan and console (i installed a 2nd nic in my desktop) push a button or 2 and bam config loaded.

LOL

The cheat sheets are pure gold! Pretty much got them all printed out and on file! Good for someone like me that doesnt have a photographic memory!
