Yow, your post could use a little formatting.

In any case SO_REUSEADDR isn't going to help you launch two apps that bind to the same port at the same time (10048 in this case).

SO_REUSEADDR is only useful when you want to fire up something even though the port is still in a TIME_WAIT state. This isn't permitted normally, as there is a small chance that you could get unexpected data from an old session on the port.

If you are really determined to try it:

setsockopt(SOCK, SOL_SOCKET, SO_REUSEADDR,1) || die "setsockopt() failed: $!\n"; -- or from IO::Socket -- $sock = IO::Socket::INET->new( Reuse => 1, ...Other settings here );
It does sound like you are using a client, and not a server though. Re-read your own excerpt:Client programs usually need not call bind at all
