As Brian said, the file is saned.conf.

So for this part, we are really talking about how to run saned on the
server machine.
Depending on the distro and how they packaged it, you might find that
saned is already running or set up to start on demand.

Perhaps check to see if a saned process is running. You could also see
if a service manager is listening on your behalf:

netstat -an | grep 6566

In my case:

tcp6       0      0 :::6566                 :::*                    LISTEN

With the above, you should be set.
If it is not running and no-one is listening on the port, you could run
it manually for testing purposes.

E.g.
saned -l -p 6566 -b 192.168.1.12 -e -d5

The address and port should be configured to what you desire. Port 6566
is the default port so you should probably stick to that.

Cheers,
Ralph
