PEAR Net_Ping binary not found

PHP
1

Hey everyone,
I’m having some issues with the Net_Ping PEAR extension I installed into my remote web server. When I try and execute the script, I get an error saying:

“unable to locate the ping binary”

I’m not 100% what’s going on here. Here is how I am calling the script (which I don’t think is the problem):


    require_once "Net/Ping.php";
        $ping = Net_Ping::factory();
	if (PEAR::isError($ping)) {
    	echo $ping->getMessage();
	} else {
    	$ping->setArgs(array('count' => 4));
    	var_dump($ping->ping('google.com'));
	}

Any ideas on how to get this working? I’ve googled the error and I came across the cPanel Knowledge Base which states that I need to change the PHP.ini:

WHM -> PHP Configuration -> Switch to Advanced Mode -> remove from disable_functions the functions exec and popen and save the new configuration.

However, it being a remote server I cannot do that. I have other PEAR extensions that work just fine (for instance a port checker). Not sure why this isn’t working.

Any help would be MUCH APPRECIATED!

Its not working because it cannot find the program “ping” on your server. This is equivalent of not having ping.exe on a Windows machine.

That’s interesting as I installed it and everything said it checked out. So you’re saying it’s a problem that my web server admins will have to look into?

Yes, they’ll need to fix it for you.

Be aware they may not do so if you’re on shared hosting, as it would give you access to more functions on the server.
