If ncpa.cfg is not modified then the services start but the listener does not listen on port 5693. The log contains the error

The comment in the ncpa.cfg says
# Default: port = 5963
I assume this is a typo. I checked port 5963 and the listener is NOT listening on that port either. When I manually specify port = 5693 then everything works fine.

For reference, could you post your exact, and entire NCPA configuration file for us to review?

You're right, that is not an actual default - if you do not specify anything ... it will error out. I can add this to the list of bugs to be fixed for the next release.
