Do not let the title fool you "Unix Network Programming" spends a great deal of time on internet networking - perhaps more so than on AF_UNIX. http://www.amazon.com/Unix-Network-Programming-Sockets-Networking/dp/0131411551/ref=sr_1_1?ie=UTF8&s=books&qid=1270241419&sr=8-1 This would probably make a good companion: http://www.amazon.com/Data-Computer-Communications-William-Stallings/dp/0132433109/ref=sr_1_1?ie=UTF8&s=books&qid=1270241586&sr=1-1 rick jones -- Process shall set you free from the need for rational thought. these opinions are mine, all mine; HP might not want them anyway... :) feel free to post, OR email to rick.jones2 in hp.com but NOT BOTH...

Should I have > done that? Simple answer: Yes. Complicated answer: The third argument to 'socket' is a protocol number (see /etc/protocols for a list). Using '0' means 'chose the default'. For PF_INET SOCK_DGRAM sockets, this is UDP, and for SOCK_STREAM socket, TCP. > Or should I leave the port numbers the way they are? Port numbers belong to transport layer socket addresses. They are part of the input for connect(2) or bind(2).
