Right, but if the machine name isn't one of the allowed machines, what action does the trigger take?

My understanding of login restriction at the listener level is that it is possible only to limit all database logins based on machine. I've been experimenting with login triggers that inspect sys_context('userenv','host'), but haven't figured out how to prevent the session from proceeding if the client machine name is not in the approved list. If anyone has any ideas or suggestions I'd be most grateful.
