Thanks. Yet more newbie questions:

1. Is it better to (a) list 4 sources on the box with the GPS receiver
attached and just one source on all client boxes that point to it for
ntp, or (b) list 4 servers on all boxes?

2. If (b) should I use the "prefer" directive to query the GPS-based
server first?

many thanks
