Sockets na hostingu NoLimit

Dobrý den,

Chci na webhostingu používat sockets, ale hází mi to tuto chybu:

Warning: socket_bind(): Unable to bind address [98]: Address already in use in /data/web/virtuals/280302/virtual/www/socketSrv.php on line 9

<?php
$host = $_SERVER['SERVER_ADDR'];;
$port = 65000;
// No Timeout 
set_time_limit(0);
 $socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
 $result = socket_bind($socket, $host, $port) or die("Could not bind to socket\n");
 $result = socket_listen($socket, 3) or die("Could not set up socket listener\n");
 $spawn = socket_accept($socket) or die("Could not accept incoming connection\n");
 $input = socket_read($spawn, 1024) or die("Could not read input\n");
 $output = strrev($input) . "\n";
 socket_write($spawn, $output, strlen ($output)) or die("Could not write output\n");
 socket_close($spawn);
socket_close($socket);

Jakou mám použít IP a Port pro sockets?

Zkoušel jsem nastavit $host na localhost, 127.0.0.1, doménu i $_SERVER[‚SERVER_ADDR‘]
