Gary,
You must not use localhost or 127.0.0.x in any bacula configuration
file, anywhere. It will not work correctly if you do. You are seeing
the results of that mistake in your system now. If bacula does not
initially work with a static IP or FQDN, we must troubleshoot why and
resolve the issue.
The bacula configuration files you must check are:
bacula-dir.conf
bacula-sd.conf
bacula-fd.conf
You can search your system for these files with:
sudo find / -type f -name 'bacula-*.conf'
Please run that find command on both your workstation and your
server, and reply with the output, indicating which system gave which
output.
The files are all in /etc/bacula.
It seems to me that if you shouldn't use localhost / 127.0.0.1 in a
configuration file, the default configuration files shouldn't use it.
Instead they should use a descriptive meta-value such as <network name
of the storage device> or <network name of the changer>. This would
prevent the services from starting until the values are replaced with
something legitimate. They would also remove the need for multiple
comments (most of which are NOT currently in the files) about what the
value should not be.
As you discovered, localhost, 127.0.0.1, ::1 will indeed work, but if,
and only if, all 3 daemons, DIR, SD, and client, are on the same
machine. If you have any other machines to backup via the network, then
both server daemons and clients MUST use a network IP address. This is
because DIR must be able to connect with the client machine, and the
client must be able to connect to the SD. If DNS for the local domain is
available to all involved machines, then domain names may also be used.
What happened is that DIR connected with the client and commanded it to
connect to the SD to begin a backup job. However, the config files show
that SD is located at 127.0.0.1, so the DIR told the client to connect
to the SD at 127.0.0.1. The client then tried to connect to 127.0.0.1,
rather than the SD's IP address. It is an impossible config.
