SUMMARY: /etc/ethers How to build

I am using the /etc/ethers file with a program called etherman. The program
monitors network traffic and displays it. It uses the /etc/ether file to
lookup the names of the machines.

Here are the replies:

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,,, ..., and capture the output. -----------------------

Also, one may also ping all the routers and then do an arp -a and most of them show up.
