Two listeners for 7.3?

Hello out there,

how do I set up two listeners for one Oracle 7.3 instance (NT4.0). The problems is the following:

We have installed a second ethernet card into our server wich has a different IP address. But the standard listener just listens to one IP address. I tried to add the new IP address to listener.ora but this did not work.
My second try was to duplicate the contents of listener.ora and replaced the word 'listener' with some other name, but lisnrctl did not want to start a second listener.
I tried the following command sequence:

set current_listener newlistener
set password <password>
start

But this gives me the message the listener 'listener' is already running. What did I do wrong?

Many thanks in advance,
Lothar
