Re: raw sockets
Thanks for all the answers so far. I forgot to mention that the connection will be done using a crossover ethernet cable, if that's relevant.

The definitive work on anything sockets-related is, I believe, still W Richard Stevens' excellent book UNIX Network Programming, volume 1. http://www.amazon.com/dp/0131411551/ Perhaps it's a bit pricey for a student, but if you can get hold of a copy then that (and volume 2) will be all you'll ever need. :-) Also, if you are serious about UNIX programming, you'll absolutely want his Advanced Programming in the UNIX Environment as well. Oh, I just noticed that you can still buy copies of the first edition of UNIX Network Programming: http://www.amazon.com/UNIX-Network-Programming-Richard-Stevens/dp/0139498761/ That's an even better buy. It contains most of what's relevant from the two newer volumes, AND it contains the third volume about applications that Stevens never finished before he died in 1999. The newer edition has way more detail and is better as a reference, but you can't beat the first edition for educational purposes. Ah, bummer, the first edition doesn't cover raw sockets, so it won't help you in that regard. But it's still one of those rare technical books that you can easily read cover-to-cover (only to find out in the end that the butler didn't do it - it was the server!).

The specification for this assignment is similar to the Kermit protocol, if anyone is familiar with that. I wonder if any of you have some good material to point me at. Most tutorials are for Linux (and I will be the first ever in make this assignment in OpenBSD!) The man pages are awesome, but I was looking for some material that would point me at the right direction from a beginner's point of view. I've read the sockets, recv and send man pages, I would be glad to hear what other man pages are important for this project. Thanks in advance. It may be a good idea to download src.tar.gz (web interface to CVS is also nice, but you will not be able to use grep) and try to find any similar code there. Netintro(4) is definitely worth reading. Or man bpf(4), maybe?
