Anyone wanna teach a class...

From: John Aldrich 
Anyone wanna teach a class on networking? I don't mean LinkedIn and I don't 
mean making Ethernet cables. :D I screwed the pooch on an interview with 
Amazon, at least partly because I don't know much about the layers of 
networking, and the various protocols that make up TCP/IP and things like 
I'd like to be more prepared for my next interview, whenever that is.

=============================================================== From: Aaron Welch ------------------------------------------------------ LOL... My CCNA instructor mentioned that. -AW

=============================================================== From: Kenneth Ratliff ------------------------------------------------------ Certainly. To truly understand networking, you need to begin at the beginning. And that means TCP/IP. Which is something that bores the crap out of people horribly, but a solid understand of the TCP/IP protocol suite is absolutely necessary to be any good at networking. It frustrates the hell out of me when I see these newly minted CCNA's talking like they know something, and they can't even explain how ARP works. So my personal recommendation is to start here:

=============================================================== From: Kenneth Ratliff ------------------------------------------------------ Nope, layer 8 is the politics layer. Stupid users aren't usually being political, they're just being stupid.

=============================================================== From: Kenneth Ratliff ------------------------------------------------------ Oh, and I would be totally remiss if I didn't mention Network Warrior by Gary Donahue. it's subtitle is 'Everything you need to know that wasn't on the CCNA'. It's essentially a brain dump from a 20-year veteran of network administration and engineering. The author's personality is very enjoyable, and he is very practical is in his approach to explaining how things should be put together, as well as the pitfalls of making certain design choices. The last few chapters deal with the politics of being in IT, and the chapter entitled 'How not to be an IT jerk' should be, IMHO, required reading for everyone in IT. The Practice of System and Network Administration is also another damn good tome. It's not targetted specifically at networking, but at the proper way to run a technology company in general, and how the network fits into that is very relevant. The author, Thomas Limoncelli, also wrote Time Management for System Administrators, another book which I feel should be required reading for all IT staff
