You probably haven't been seeing it, because there is no concept of connection in TCP/IP stacks until you hit TCP, but here's how your connection kinda works (at least on 2 *nix boxen): peer<-->socket filehandle<-->transport<-->socket filehandle<-->peer "transport" here can be one of many things, such as: socket fd<-->unix domain socket<-->socket fd or socket fd<-->TCP<-->IP<-->ip transport(LAN/PPP/X.25/SmokeSignals)<- ->IP<-->TCP<-->socket fd Now, if you actually mean "what octets mean and do", those are actually defined higher than TCP, and are laid out in the specs for those respective protocols. i.e.: Telnet Protocol: RFC 854/855 FTP: RFC 959 TFTP: RFC 1350 POP3: RFC 1939 HTTP/1.1: RFC 2068 Hope that helps. -- Love is like a friendship caught on fire.
