Port Scan !

[d.shankar]

I have this port scanner code in PHP.

It is ultimately dead slow ... Is it how it works ??

Cant it be remodified ?

 

<?php
$host = "www.google.com";
$start = 0;
$end = 65535;

for($current = $start; $current <= $end; $current++)
{
$service = getservbyport($current, "tcp");

$result = @fsockopen($host, $current);


if($result)
	{
	echo $current." Port is <font color=\"green\"><b>OPEN</b></font><br>";
	flush();
	}
	else
		{
		echo $current." Port is <font color=\"red\"><b>CLOSED</b></font><br>";
		flush();
		}
	}

?>

scanning all ports will always be slow!, you could shorten the timeout but then you could get some bad results

play with the timeout see what happens but slow servers will seam to have closed ports when their just slow!

$timeout = 30; //change this 
$fp = fsockopen($host, $current, $errno, $errstr, $timeout);
