# This is for a dedicated primary server connected to four reference

|
# clocks and providing service via multicast, broadcast, manycast and
|
|
|
|
|
# the usual suspects. It blocks previous versions and limits clients
|
|
|
|
|
# per network to two and returnd a kiss-of-death packet if the
|
|
|
|
|
# sender is blocked. Note that the precise fudge factors were

|
|
|
# determined using the calibrate feature and that the kernel PPS

# discipline is selected.
