Php port scan script

[netpumber]

hi!!

 

i have wrote this script.. as a port scanner:

<?php
ini_set("display_errors", 1);
$host = "www.site.com";
for($i=50;$i<6669;$i++) {
$fp = @fsockopen($host,$i,$errno,$errstr,10);
if($fp)
{
echo "port " . $i . " open on " . $host . "\n";
@fclose($fp);
}

flush();
} //end for
?>

 

It scans just for open ports in the hostname. I run it through console and it prints results but to slow.. Also if i runt through web browser doesnt seems to work.. Have you any idea on how to make it faster and work through browser ?

 

Thanks for any of your answer

You have a 10 second timeout.  If the port is not open then you'll have to wait 10 seconds for it to time out and return (I think).  I'm guessing that's why it's so slow.

 

To speed it up, I'd fork child threads and have each thread check a pool of ports.
