monitors network traffic and displays it. It uses the /etc/ether file to
lookup the names of the machines.

running rup (to build up a decent arp table), followed
by arp -a piped into an awk script should get you started.

There's a program Dave Curry wrote some time ago called 'getethers'.
Basically you give it a network address and it pings everything on it
and writes the ethernet addresses it finds to a file. I don't have an
ftp site handy, but maybe archie can find it for you.
Of course you could also just write a shell script to ping, say,
192.1.1.1, 192.1.1.2, ..., 192.1.1.254 and capture the output.
-----------------------
Also, one may also ping all the routers and then
do an arp -a and most of them show up.
