I was shocked when i saw the /var/log/messages filled with large number of entries like

“server named[15166]: client [xxxx.xxx]#975: error sending response: host unreachable“.

I was running my own bind DNS server and initially i thought that this has something to do with dos attacks. There were about 100′s of above entries per day originating from few IPs and i was very suspicious about it.

I did check my firewall rules and port 53 was open for both UDP/TCP. So no problem there.

i wrote a simple php script to check whether the website or Ip address is online or offline. All you have to do is specify a website url or ip address and the script will return with ONLINE or OFFLINE. I used php fsockopen() to accomplish this.

$status = GetServerStatus(‘http://domain.com’,80)
or
$status = GetServerStatus(‘IPAddress’,80)

<?php
function GetServerStatus($site, $port)

$status = array("OFFLINE", "ONLINE");
$fp = @fsockopen($site, $port, $errno, $errstr, 2);
if (!$fp) {
return $status[0];
} else
{ return $status[1];}
}
?>

This is a tricky problem when parsing url to get domain …
