Im looking for information on decoding packets. From my limited internet research i see that there are some libraries like pcap which allow me to intercept the packets, but i am trying to figure out how to decode the data contained within the packet.

Aside from that i would like to know more about the inner workings of packets, so--altough it is what i need right now--i am not really looking for a short answer like "byte locations x through y determine this, etc". I want to broaden my knowledge of networking and would rather be directed to more comprehensive resources.

So are there any network security books you guys recommend? Preferably java related, but im open to anything...
 
TCP/IP Networking by Doug Comer is an excellent resource. It's one of the "bibles" of the business.

Good Luck

Also, be sure to check out ethereal. It won't necessarily teach you how various protocols work but it will give you a nice breakdown of real packets. Observing the stuff in reality is very helpful when reading the specifications from a book.

bingo, you can read all you want but until you see the actual packets it doens't make much sense.

ethereal is great, and its free.
