make ping with PHP
 
I would like to make a simple monitoring. I make this:

Code:
<?php
$ip = $_SERVER['127.0.0.1'];
exec("ping -n 4 $ip 2>&1", $output, $retval);
if ($retval != 0) {
echo "no!";
}
else
{
echo "yes!"; }
?>
I use my internal IP: 127.0.0.1.
The result is: NO!

why???

I change this code and I put this:

Code:
IP: 10.110.206.123 (
<?php
$ping_ex = exec("ping -n 1 10.140.206.123", $ping_result, $pr);
if (count($ping_result) > 1){
echo "<img src=\"on.png\">";
} else{
echo "<img src=\"off.png\">";
}
?> )


IP: 127.0.0.1 (
<?php
$ping_ex = exec("ping -n 1 127.0.0.1", $ping_result, $pr);
if (count($ping_result) > 1){
echo "<img src=\"on.png\">";
} else{
echo "<img src=\"off.png\">";
}
?> )
In the first case the resulst are NO and the second case are YES.
But... the result is YES in two cases. Why???

yeah!
finally I put this code:

Code:
<?php
$str = exec("ping -n 1 -w 1 100.100.100.100", $input, $result);
if ($result == 0){
echo "<img src=\"on.png\">";
}else{
echo "<img src=\"off.png\">";
}
?>
It's run correctly, but i would like to insert this code into a javascript function because I insert many times this PHP and the page is very hard to load.
I would like to insert a button:

Code:
<input type="submit" onClick="para();">
and when I press this button, the javascript runs.
Is it possible??

So, can this code be used for performing DOS attacks on sites??
