Listener Log Question


In my listener.log I'm seeing entries showing two different values for HOST, bb7b and bb0.
What is the source of that second host, HOST-bb0?

Likely.  Change the hosts entry real quick and try it.

There is a machine somewhere named bb0 that connected to your database.

You can try to lcate information on it from the OS with:
nslookup bb0
and/or
ping bb0

This is Solaris.
Ping just says bb0 is alive and nslookup  is either not on Solaris or not available.
Now the /etc/hosts file does have an entry:
127.0.0.1       bb0
That's to prevent anything from actually going out to the real bb0.
What I'm trying to figure is what configuration file or setting somewhere accounts for that entry in the listener.log file.  Listener.ora has no bb0 entry neither does tnsnames.

The listener.log file logs what it is given.  There is nothing to configure that allows that entry.

You must have logged in to the database through the loopback (127.0.0.1).  The connection passed 'bb0' as the machine name off to the listener and the listener logged it.

Or, someone from the real bb0 connected to the database.

A hostname will return bb7b.  I logged in through bb7b which in it's /etc/hosts file has a 127.0.0.1 entry for bb0 host.  Is that second HOST=bb0 coming from /etc/hosts?

I'll see if I can get permission in a couple hours.
