How do you handle a server restart?

We use listener passwords with Oracle 10g and previously with 9i as
required by our auditors. The interactive password setting is not
usually an issue since you only need to stop/start the listener when the
server is being shutdown or when maintaining the listener itself. For
our cold backups, we shut the db down, but not the listener; it stays
running all the time.
From my research on the issue, I believe the only way to
programmatically shutdown/start the password protected listener would be
to utilize a program that executes keystrokes just as if a user were
typing in the commands from the keyboard.

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.

realize that there are vulnerabilities but if they're able to get at the
network, why would they waste their time on the listner?
