I'm using the script below to listen on a port on a server. Then there is a 2nd server probes this port. But the 2nd server got an error "tcp time out" due to my socket does not send FIN ack to finish the tcp connection. Any ideas?

use IO::Socket;
my $sock = new IO::Socket::INET (
LocalHost => '12.34.56.78',
LocalPort => '1350',
Proto => 'tcp',
Listen => 10,
Reuse => 1,
);
die "Could not create socket: $!\n" unless $sock;
listen ($sock, 3);
close($sock);
