Hi,

frankly speaking, the fact that this worked on *any* OS amazes me - only shows
how broken Lunix is, haha... 

Anyway, two ressources I've found most useful when I started to deal with 
socket programming are:

- Beej's Guide to Network Programming - Using Internet Sockets

http://www.ecst.csuchico.edu/~beej/guide/net/

Amusingly written and 100% free, lots of examples.

- W. Richard Stevens: Unix Network Programming, Vol.1

As all of Stevens books, this is a superb didactical masterpiece and a good
reference in one. The books aren't cheap, but you'll save buying two or three
with a lot less value.

Cheers, Jan
