I have two Ubuntu computers. A server (Blue) and a workstation (red).
I thought I would set up Blue as a NTP server, and have red get time
from it and the pool.
Blue says its time is good, but red says blue is an outlier.
Blue is a 3.0 GHz Pentium, with 512M RAM and not doing anything else at
the moment (not even file serving). They are connected together with an
8 port switch. So there is no distance between them.
Here is Blue:

Why does red not use the data from Blue?
What would cause Blue to have so much jitter when they are so close
together? Do I have something set wrong?
