The first question would be do you need to do anything special at all.
You only need that sort of solution if you are going to g

Ok, so in a more complicated situation where every node is equipped with GPS
but the GPS sometimes is not delivering the signal in all nodes but one, the
ntp.conf in every node should have these lines:
server node1 iburst
server node2 iburst
server node3 iburst
server node4 iburst
...
server no

Everything works after I enabled Orphan Mode with "tos orphan 5" in ntp.conf

I have two Symmetricom S200s with GPS antennas making them stratum 1. Clients
use three (Eventually to be four) Stratum 2 S200's for synchronization. The
stratum 2s use the GPS based Stratum 1s for synchronization. My question is
should I have a server or peer relationship between the Stratum

NONONONONO Never use the local clock driver. It is useless. It is asking
the clock itself for its time in order to discipline its own time. Makes
no sense. What he meant was that you need another real time source
