Something's already on the port you try to bind() your socket to, _or_ the
socket is in SOCK_WAIT state..which means there's nothing connected to it,
but the kernel hasn't freed its resources yet.
To fix it, either wait, kill the process which is on the port (hmmm, might
be a tough thing to find out who's on it...try lsof if you have it, or get
charm.il.ft.hse.nl:/pub/perl/nstat.pl, a perl script which you can use to
find out things like that), or add the following code to the server's code
(providing you have it):
/* 'sock' is the socket descriptor */
int opt = 1, sock;
...
(void) setsockopt(sock, SOL_SOCKET, SO_REUSEADDR, &opt, sizeof(int));
...
(add this _before_ you bind()).
