You can trace down the system call socket. The counterpart in the kernel is sys_socket. after that u can trace down the system call bind (sys_bind in kernel). Basically when a socket is created using socket system call, a "struct socket" (and "struct sock") is created and put into the protocol specific (not ftp, http, etc... here its IP, UNIX, etc..) hash chains. Example is function inet_create 418 /* Add to protocol hash chains. */ 419 sk->sk_prot->hash(sk); Later bind is called with a port number (HTTP 80, FTP 21 and anothers) this number is binded to the "struct sock" > > thanks, > Luis Henrique.
