Re: why do the comments in bacula-dir.conf say not to use "localhost" here?

I'm running avahi - needed to share printers. Avahi-daemon -s shows it 
is running. And my servers are also defined in /etc/hosts. Any test that 
requires name resolution works.

I am not running a firewall on the server. The only firewall I even ever 
looked at was ufw and it is not installed.

When I use 127.0.01, bconsole shows the client is reachable and working 
properly.

However, I am having a problem reaching my workstation, which is 
similarly not running a firewall. I get
[DE0029] Unable to connect to Client: <client name>-fd on <client 
IP>:9102. ERR=Connection refused

I don't know if this is related or a separate issue. The fd is running 
on my workstation, and the fd name and password are the same on the 
server and workstation.
