exec ("/sbin/e-smith/dynamic-dns/$service",
$ipaddress, $account, $password, $domain)
or die "Couldn't exec /sbin/e-smith/dynamic-dns/$service: $!";
}
exit (0);
and then you'll need a database for that file to point too, but that's out of my scope, maybe someone else can help you with that, unless you already know what to do.
hope that helps
cheers
