 Posted: Thu Mar 29, 2007 8:40 pm Post subject: Cannot Net_Ping::ping() from inside Apache |
 |
|
I'm writing a web app that attempts to ping a system on the network to determine if the system is alive. When I run the following code from the console, things work great:
| Code: | <?php
require_once('Net/Ping.php');
$ping = Net_Ping::factory();
$address = '192.168.1.1';
$result = $ping->ping($address);
if ( PEAR::isError($result) ) {
echo "Host is not up (";
echo $result->getMessage;
echo ")\n";
} else {
echo "Host is up and replied (";
echo $result->getReceived();
echo ")\n";
}
?> |
Result:
| Quote: | | Host is up and replied (3) |
When I try to run the same code under Apache 2.2.3 on Fedora Core 6 (PHP version 5.1.6), the Net_Ping::ping() command always returns with an 'unknown host' error.
Any advice on how to fix this?
Thanks!
