Thanks for the help so far, making progress. I have set localhost for
the hostname in the FE database configuration, and in mythtv-setup the
local backend and master backend are both set as 127.0.0.1.
At this point I can get the FE to connect to the BE however the only way
I can start the BE is as the root user, it is not starting
automatically. If I start is as --user mythtv it will fail to run.
Command line output for both is below - I note a couple of things about
this when starting as "--user mythtv", the obvious thing being it
complains about the BackendServerIP (it is set as mentioned above), "no
address defined for host", where is this looking or where should this be
set? And the testing network connectivity to 192.168.1.100 is actually
my own BE myth box, why is it testing against that?
