TCP/IP stack responses
I am looking for a read on common responses from TCP/IP stacks to TCP packets with different flags set. (example: If a FIN packet is sent a ReSeT packet is usually returned; something along those lines but with more detail and examples) OS fingerprinting techniques achieve their findings by knowing this quite well. I am wondering if this is documented anywhere. I have searched google but I may not be using the correct search phrases. I have tried TCP/IP stack responses and "TCP/IP stack" flag returns. Any help will be greatly apreciated, and I thank you in advance.

Why dont you check out the pages for tools that do fingerprinting? there is a good bit at http://www.insecure.org/nmap/nmap-fi...g-article.html , you may want to check out the tutorials by the horse13 here at AO also

If you really want to know about the nitty gritty details of TCP/IP buy "TCP/IP Illustrated" by Richard Stevens. It's considered the bible of TCP/IP. You'll only need volume 1 if you're only interested in the protocol itself. Volume 2 covers socket programming and Volume 3 covers the more 'advanced' protocols like TLS.
Experience is something you don't get until just after you need it.

I greatfully read all of thehorse13's Nmap tutorials and eagerly waited for each new one. I am also anticipating Fyodor's book when it is released .
I will find this TCP/IP Illustrated book and read it and also browse the site listed above.
Thank you all.

I just finished my class on TCP/IP this semester. I am going to attach a few things that may help you. Do yourself a favor; rename these to .doc instead of the .txt ok?
