I've tried ping but it's not very reliable for IP's having firewalls, the ping will never come back and the script will erroneously report that the IP is down but is actually a 'live' one. It's the simplest to make though: 
#!/usr/bin/perl

# IP adress or hostname of the remote machine to test
$remote = "192.168.0.2";
if(system("ping -c 1 $remote 1> /dev/null"))
{
    print "$remote is down\n";
}
else
{
    print "$remote is up\n";
}
