All,
I have a very dumb question, regarding what information is correct,
and what is not.
The documention states that MD5keys will be lss then or equal to 16
characters in length, and consist of a printable ASCII characters and
be terminated by whitespace or #. Yet the output of 'ntp-keygen -M',
an
Just a small correction...

Depends on the network or reference clock, and the resolution to which
the local clock can be read.
