Hey all. Ok, I was wondering if anyone could point me to good books or online starting tutorials on exactly how networks work, and how various networking and internet protocols work. Basically, I am new to Network programming and theory, and want to have a good understanding of how Protocols such as UDP, TCP/IP, PPP, DHCP, ICMP, and others work. I also want to understand how different computers running different operating systems can communicate with each other, such as a MacOS X server hosting GNU/Linux and Windows clients. Basically, I want a good beginners/advanced book on Networking theory and Networking Programming. Can anyone help me please? My game engine needs networking ability, even though it''s in its early stages of developement. thanks. Edem Attiogbe
