Thanks to everyone for your help.  We figured out how to add the correct
language to our startup and takedown scripts to account for the
password.  We're still not sure if we're going to use a password but at
least we know how to implement it correctly.

I also thought that you could start the listener without a password; you
just couldn't shut it down without supplying a password.  But since I
wasn't sure, I decided not to bring it up...

I'm pretty certain that in 9i the listener will restart after a reboot
even if it is password protected.

Wouldn't they need access to your network in order to access the
listener? I know that you can set up a similar entry in a listener.ora
and remotely access the listener (I did this to prove it) but I was
behind the firewall. I tried from home but wasn't able to access the
listener using the same technique. 

Another question is that in 9i you can't do a save_config and have to
enter the password interactively in order to use the listener. So, after
a cold backup and a server restart, someone would have to manually
restart every listener. 

Has anyone figured out how to script this? We tried but weren't able to
figure out how to script the password entry so that our startup scripts
would work with a password protected listener.

Several things they could do, for one they could turn off logging when
you need it.  They could also turn on logging, fille up the drive that
the log file is on, and stop your listener, they could shut down the
listener so no one could connect.  ALl of these could be accidental or
on purpose, but a password makes it harder to do either way.  Also, most
Sarbanes-Oxley compliance checklists require it.

It is a pain to deal with even so.

Is anyone out there using lsnrctl passwords?  If so, why?  I realize
that there are vulnerabilities but if they're able to get at the
network, why would they waste their time on the listner?
