Ping Script

webmasternovis

Hi all,

I've made a small script that will ping another ip and bring back details, but the problem is it's pinging from the server. Would anyone be able to tell me a script that will ping another IP, from the users IP instead of the server one?

Cheers,
Mike 🙂

php runs on the server not the client... what did you expect?

I'm just asking, is there a way you can ping from an IP other than the server?

You might actually be able to do something through sockets, how are you pinging this server? Simply exec()ing the ping command? Can we see your code?

Hi,

My code is as follows, I adjusted it after seeing it posted here somewhere...

// Ping function
function ping($link) { 
        $link = preg_replace('![url]http://www.[/url]!','',$link); 
        $link = preg_replace('/:.*/','',$link); 
        $cmd = `ping -c1 -w1 $link`; 
        if (preg_match('!time=(.+) ms!', $cmd, $m)) {
                print "(ping: " . $m[1] . ")"; 
        } else { 
                print "<font color='red'><strong>DEAD</strong>"; 
        } 
}

Could it work?

Cheers,
Mike

There is a ping example in the manual entry for [man]socket_create[/man], that coupled with [man]socket_bind[/man] may get you somewhere. Sorry, I dont have time to play with this atm.

Still, PHP runs on the server and thus - in principle - cannot execute these kinds of commands on behalf of the client. The only possiblity to do so is by spoofing ping packets with the clients IP address.

Hmm... ok.

I'm trying something else regarding pinging. Does anyone know why I can't ping my own IP using a script? From talking to a few friends it doesn't work for them when they use their own IP either.

Anymore help?

Cheers so far.

Mike
