I have the script that listens on sockets (script 1). However on some domains it is not working on unknown reason.

I wrote another script that connects to this socket (script 2):

<?
$fp = fsockopen($domain, $port, $errno, $errstr, 5);
var_dump($fp);
?>

Script 2 should check if script 1 is working. If script 1 does not work then var_dump will display null, otherwise var_dump will display resource variable.

Now, if I upload script 2 to the same host as script 1 then script 2 connects to script 1 and var_dump displays resource variable. However, if I upload script 2 to a different host then script 2 can not connect to script 1.

In other words script 1 accepts socket connection only from the same computer it is installed on. Why is it so and how can it be fixed?
