Unless someone has done something really bad to current versions of the
code, enable/disable auth has nothing to do with ntpdc control commands
- those *always* require authentication, and if you haven't configured a
key file, they just cannot be done. If (as you claimed earlier) your
config got changed by someone else, you have bigger problems to chase
(as in someone has broken into your system). I suspect that you were
just seeing a badly-behaved client trying to get time from your server,
