This isn't really a PHP question, since ping is a command in the OS and not in PHP itself. And of course, you didn't mention what OS you run. I run FreeBSD. In FreeBSD, ping has options that could be used thusly: $target="209.238.46.67"; exec("/sbin/ping -c 1 -t 3 $target", $junk, $ret); if ($ret==0) // In shell, 0 means success print "Wahoo! I can see $ipaddr!\n"; else print "Bummer... $ipaddr seems to be down.\n"; The option -c specifies a "count" (the number of pings to send), and -t specifies a timeout in seconds. If your operating system is UNIX or Linux, you can "man ping" from a shell to see what you need to do to duplicate this functionality, or check out various OS man pages at http://www.freebsd.org/docs.html#man . If you're running a Microsoft operating system, you're most likely out of luck. -- Paul Chvostek <paul@it.ca> Operations / Abuse / Whatever +1 416 598-0000 it.canada - hosting and development http://www.it.ca/
