# Hereafter should be "server" or "peer" statements to configure other
|
||
|
|
# hosts to exchange NTP packets with. Peers should be selected in such
|
||
|
|
# a way that the network path to them is symmetric (that is, the series
|
||
|
|
# of links and routers used to get to the peer is the same one that the
|
||
|
|
# peer uses to get back. NTP assumes such symmetry in its network delay
|
||
|
|
# calculation. NTP will apply an incorrect adjustment to timestamps
|
||
|
|
# received from the peer if the path is not symmetric. This can result
|
||
|
|
# in clock skew (your system clock being maintained consistently wrong
|
||
|
|
# by a certain amount).
|
||
|
|
#
|
||
|
|
# The best way to select symmetric peers is to make sure that the
|
||
|
|
# network path to them is as short as possible (this reduces the chance
|
||
|
|
# that there is more than one network path between you and your peer).
|
||
|
|
# You can measure these distances with the traceroute(8) program. The
|
||
|
|
# best place to start looking for NTP peers for your system is within
|
||
|
|
# your own network, or at your Internet Service Provider (ISP).
|
||
|
|
#
|
||
|
|
# Ideally, you should select at least three other systems to talk NTP
|
||
|
|
# with, for an "what I tell you three times is true" effect.
