Tim, a few of things to be aware of and to not confuse:


1. On Linux systems (and probably other *nixs) the default method for an
application to connect to a MySQL db when the application and client are on
the same machine is via unix socket, not via TCP. On Gentoo servers this is
default: /var/run/mysqld/mysqld.sock  it is surely somewhere else on other
distros though. :)

2. bconsole connects to bacula-dir via TCP port 9101 and does not use a unix
socket for communication.  bconsole also does not talk to the database,
bconsole talks to bacula-dir, and bacula-dir talks to the db.

3. If your bconsole is local to the machine that bacula-dir is running on, and
bacula-dir is bound to all interfaces (the default setting), then you can
always set the "address = " that bconsole connects to to either "localhost",
"127.0.0.1", or an IP address bound to the server's ethernet NIC(s).

4. Setting a name in /etc/hosts is (almost) always the wrong thing to do.
Especially pointing the name to localhost (127.0.0.1).

You will surely end up with unexpected results somewhere else down the road.

If you want/need to use a FQDN instead of an IP address to connect to systems,
you should create and maintain "A" records in your dns server.

5. You did not need to restart the bacula-dir since it was already running,
and bound to TCP/9101 on all interfaces as we previously determined.


Hope this helps to clarify some things.


Bill
