fast ping ?!!

Anon

I need to ping a lot of boxes (whole subnet)
in a php script..
but scripts that use that ping command
take a lot of time since the shortest
timeout for ping is 1 second (ping -w 1)..

Does anyone know of a way to ping several
boxes at once, or to speed up the pings?!

TIA for answering

Hi,

On my unix box i can ping a whole i.p range like on my network i would do:

ping 212.135.179.1-254 -w 1

so on php i could use:

<?php

system("ping 212.135.179.1-254 -w 1");
system("ping 212.135.179.50-254 -w 1");
system("ping 212.135.179.150-254 -w 1");
system("ping 212.135.179.200-254 -w 1");

And just layout what ip addresses to ping. You cant ping a whole subnet from php as it used to many resources.
