How to use the wakeonlan perl script instead of etherwake.exe

I had a problem with etherwake.exe when crossing multiple subnets and could not get Wake On Lan to work so I tried the wakeonlan perl script located here /usr/bin/, with some minor edits to the wol.php file located here /var/www/fog/wol/. Wakeonlan perl script allows you to add subnet masks using the -i switch and that is what I had to do for each subnet I needed to reach.

Below is a sample copy of my wol.php file...

<?php
require_once( "../commons/config.php" );

$conn = mysql_connect( MYSQL_HOST, MYSQL_USERNAME, MYSQL_PASSWORD);
if ( $conn )
{
	@mysql_select_db( MYSQL_DATABASE );
}

require_once( "../commons/functions.include.php" );

$mac = $_GET["wakeonlan"];
if ( isValidMACAddress( $mac ) )
{

	$wol = "/usr/bin/wakeonlan";

	exec ( "$wol -i 10.1.1.255 $mac" );
        exec ( "$wol -i 10.2.2.255 $mac" );
	exec ( "$wol -i 10.3.3.255 $mac" );
	exec ( "$wol -i 10.4.4.255 $mac" );
}
?>
