I don't have any idea what you are asking, so I can't answer your question. Before proceeding, it would probably be worth your while to find a copy of Stevens's TCP/IP Illustrated Volume 2 and at least skim it so that you have a better idea of how the connection establishment process works. The book describes an earlier version of the BSD TCP/IP stack, but much still applies. Mike "Silby" Silbersack
