Configure REUSE ADDRESS MULTIPLE SOCKET 2 ONE PORT

[Anonymous Monk]

I'm getting this error message when trying to launch two different applications to access a server online ...."""Can not Create Socket:10048 Address already in use""" . They say Only one usage of each socket address (protocol/IP address/port) is normally permitted. This error occurs if a program attempts to bind a socket to an IP address/port that has already been used for an existing socket, or A socket that wasn't closed properly, or one that is still in the process of closing. For server programs that need to bind multiple sockets to the same port number, consider using setsockopt(SO_REUSEADDR). Client programs usually need not call bind at all - connect will choose an unused port automatically. So, if there is an alternative to run something called SO_REUSEADDR HOW CAN YOU DO THAT FROM WITHIN WINDOWS 2000.Advice ,Help, Rescue Please..................... THE HEALTHY MONK

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
