Determine if host is up.

[Anon]

What is the fastest most efficient way to determine if a host is up.(fsocket(), ping)
I am trying to build a website that determines if my cisco routers are up or not and emails if they are down.

thanks

up.php from jtlnet.com might give you some ideas to build on. You can find it on hotscripts.com in the php server section.
