I have a ton of IP addresses that I need to visit to see if they are active. So my plan is to redirect the browser over and over again and then just use the back button to view each page. What is the best way to do this?
I will most likely have an array of IP addresses. like:
array(234.324, 2343.323432, 234.234, 234.4543)
Then I can use some sort of scripting language to loop through and redirect the browser to these. Looking forward to seeing some cool solutions.
Those do not look like ip-addresses to me, but whatever. Why don't you just make your code fetch each of the pages you are interested in checking?
That is not recommended.
If you have a PHP-capable server, you can ping each domain:
<?php
function pingDomain($domain){
$starttime = microtime(true);
$file = fsockopen ($domain, 80, $errno, $errstr, 10);
$stoptime = microtime(true);
$status = 0;
if (!$file) $status = -1; // Site is down
else {
fclose($file);
$status = ($stoptime - $starttime) * 1000;
$status = floor($status);
}
return $status;
}
?>
Further to Kovshenin's reply, here is a tool I made recently that will be able to help you out.
