I'm unfamiliar with this particular program, so forgive me if I'm way off base...however...give this a try: function eping_validaddr($eping_hosttocheck) { return ip2long($eping_hosttocheck); } On a failure, it will return (int)-1 or (bool)FALSE depending on your PHP version. Before doing the actual ping, you'll want to grab the result of eping_validaddr() and run it through long2ip() as a final step of validation. Example: $exploit = long2ip(ip2long('127.0.0.1;commands%20here')); It will populate $exploit with (string)"255.255.255.255" (just ip2long() alone on that returns -1 in PHP4 or FALSE in PHP5). Sam
