3 # NetBSD default Network Time Protocol (NTP) configuration file for ntpd
5 # This file is intended to be both a usable default, and a Quick-Start
6 # Guide. The directives and options listed here are not at all complete.
7 # A great deal of additional documentation, including links to FAQS and
8 # other guides, may be found on the official NTP web site, in particular
10 # http://www.ntp.org/documentation.html
13 # Process ID file, so that the daemon can be signalled from scripts
15 pidfile /var/run/ntpd.pid
17 # The correction calculated by ntpd(8) for the local system clock's
18 # drift is stored here.
20 driftfile /var/db/ntp.drift
22 # Suppress the syslog(3) message for each peer synchronization change.
26 # This will help minimize disruptions due to network congestion. Don't
27 # do this if you configure only one server!
31 # Hereafter should be "server" or "peer" statements to configure other
32 # hosts to exchange NTP packets with. Peers should be selected in such
33 # a way that the network path to them is symmetric (that is, the series
34 # of links and routers used to get to the peer is the same one that the
35 # peer uses to get back. NTP assumes such symmetry in its network delay
36 # calculation. NTP will apply an incorrect adjustment to timestamps
37 # received from the peer if the path is not symmetric. This can result
38 # in clock skew (your system clock being maintained consistently wrong
39 # by a certain amount).
41 # The best way to select symmetric peers is to make sure that the
42 # network path to them is as short as possible (this reduces the chance
43 # that there is more than one network path between you and your peer).
44 # You can measure these distances with the traceroute(8) program. The
45 # best place to start looking for NTP peers for your system is within
46 # your own network, or at your Internet Service Provider (ISP).
48 # Ideally, you should select at least three other systems to talk NTP
49 # with, for an "what I tell you three times is true" effect.

55 # Public servers from the pool.ntp.org project. Volunteer's servers
56 # are dynamically assigned to the CNAMES below via DNS round-robin.
57 # The pool.ntp.org project needs more volunteers! The only criteria to
58 # join are a nailed-up connection and a static IP address. For details,
61 # http://www.pool.ntp.org/
64 # The country codes can help you find servers that are net-wise close.
65 # As explained above, closer is better...

75 #server dk.pool.ntp.org
77 # Depending on the vagaries of DNS can occasionally pull in the same
78 # server twice. The following CNAMES are guaranteed to be disjoint, at
79 # least over some short interval.
