What's with all those invalids?
I've heard of broadcast pings, but it seems that every OS nowadays doesn't respond to broadcast pings because of some old attack called the Smurf attack. Bottom line, ping -b 192.168.1.255 or on Windows, ping 192.168.1.255 doesn't work. Oh, I think I got OS X to respond to a broadcast ping. But it wasn't the only computer on the subnet.
Then there's this utility called Net World Scanner for Windows. Turns out it only works with Windows computers with a NetBIOS name - my Linux virtual machine that's not running Samba never showed up.
