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?
