Anyone got a quick script to check which ports are functioning on a range of hosts? I've lost the IP of a router on a class C network, I'd like to try connect to the telnet port of each ip and see which ones accept telnet connections. something like: 
$lip = 1;
while ($lip >= 254) {
 $ip = "192.169.128." . $lip;
   -----ATTEMPT TO CONNECT TO TELNET PORT HERE, PRINT SOMETHING IF SUC
+CESSFULL, OTHERWISE, NEXT.....

$lip++;
}

Easy to think up, another thing to do....
