Checking status of remote server 1

[geuis]

I am trying to write a tool for a website that will check to see if a remote server is up or down. Depending on the status, the web page will then report if the server is on or offline.
I would like to make this so that the page checks when a user loads the page, instead of having the script running as a constant background process, as the folks who run the webserver probably wouldn't appreciate adding major usage to the server cpu.

Any help is really, really appreciated. Thanks!

You could ping the server, and redirect the output to a text file, look in the text file to see if you're getting the right results, and echo the appropriate response.

On linux redirect to a filename combining the time, and the process id for uniqueness ($$-$now.txt)

You could also look at Net:ing which might not require the use of a text file. Hvaen't used it yet, but it couldn't hurt to look

Cheers

use Net:ing;
$host = Net:ing->new("icmp"

if ($host->ping($server, 5)) {
print "$server is up\n";
} else {
print "$server is down\n";
}
