Pings every IP in the 192.168.xxx.xxx subnet; the particular subnet to ping can be changed of course.
Waits 1 second for reply. (To change use the -t argument to ping.) Prints a success message if pingable, otherwise a '*'.

There's also a broadcast ping: `ping -b 192.168.1.255` which doesn't seem to work too well =)
Virtually nothing (except for macs!) responds to broadcast pings for some reason, although it's probably more secure that way.
It will probably crash but hey... it's cool++
