This is just the script we use. We see no need to log so we shut it off
logging each time we restart the listener. You can always turn logging
and trace on when needed. In 10 years we have rarely needed to do so.

That works??!!?
I don't see how the 'set log_status off' and 'trace off' AFTER
the "set password x" and "start" commands would make any difference. I
have my doubts, but I'll have to try that in our own environment when I
have a chance....
If that works over here, many thanks, Mark!!
Ben

This works for us. Make sure you did not use a UNIX
meta-character in the password.
$OH/bin/lsnrctl <<EOFlsnr
set password x
start
set log_status off
trace off
exit
EOFlsnr
exit

We tried scripting the startup but it doesn't accept the
password. We can set it interactively but that is very labor intensive.
lsnrctl << EOF
set password <password>
set current_listener <sid>
start
EOF

As I understand, many attacks can come from within. This
isn't about being on the internet or internal. It is a simple mechanism
to keep your listener secure. Any user in your enterprise with the
lsnrctl executable could stop the listener remotely with a password in
place.
I don't see how startup scripts are affected. You don't
need a password to start a listener. Stopping the listener requires one.
$ORACLE_HOME/bin/lsnrctl <<EOF
set password PASSWORDHASHHERE
stop
EOF

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.

they're able to get at the network, why would they waste their time on
the listner?
