I've tried googling for this, but I guess I don't know the name of a

What I'm looking for is a utility that can scan a LAN for attached
clients... i.e., computers that are attached to the LAN.

I have one box (an appliance that I have no access to), that is on
the LAN but I don't know what IP address it's using. I'd like to
complete my network map, and that is the one empty box on my chart.


If the box pings, you can simply scan your LAN like:
$ nmap -sP

Starting Nmap 4.76 ( http://nmap.org ) at 2009-03-23 11:05 AKDT

<hosts snipped>

Nmap done: 256 IP addresses (18 hosts up) scanned in 1.11 seconds

There's tons of options available (including OS fingerprinting), most of which
will require root to run as it needs on-the-fly changes to IP packets.

That did it. Beautiful. Thanks.
