This is a fake driver intended for backup # and when no outside source of synchronized time is available. The # default stratum is usually 3, but in this case we elect to use stratum # 10. Since the server line does not have the prefer keyword, this driver # is never used for synchronization, unless no other other # synchronization source is available. In case the local host is # controlled by some external source, such as an external oscillator or # another protocol, the prefer keyword would cause the local host to # disregard all other synchronization sources, unless the kernel # modifications are in use and declare an unsynchronized condition. # server 127.127.1.0 # Local clock, only use it if no other server is reachable! fudge 127.127.1.0 stratum 10 # fudge it up (-: # NTP servers from NIST for Atlantis # server 129.6.15.28 iburst # time-a.nist.gov, NIST, Gaithersburg, Maryland server 129.6.15.29 iburst # time-b.nist.gov, NIST, Gaithersburg, Maryland server 132.163.4.101 iburst # time-a.timefreq.bldrdoc.gov, NIST, Boulder, Colorado server 132.163.4.102 iburst # time-b.timefreq.bldrdoc.gov, NIST, Boulder, Colorado server 132.163.4.103 iburst # time-c.timefreq.bldrdoc.gov, NIST, Boulder, Colorado server 128.138.140.44 iburst # utcnist.colorado.edu, University of Colorado, Boulder server 192.43.244.18 iburst # time.nist.gov, NCAR, Boulder, Colorado server 131.107.1.10 iburst # time-nw.nist.gov, Microsoft, Redmond, Washington server 66.243.43.21 iburst # nist1.datum.com, Datum, San Jose, California server 216.200.93.8 iburst # nist1-dc.glassey.com, Abovenet, Virginia server 208.184.49.9 iburst # nist1-ny.glassey.com, Abovenet, New York City server 207.126.98.204 iburst # nist1-sj.glassey.com, Abovenet, San Jose, California server 207.200.81.113 iburst # nist1.aol-ca.truetime.com, TrueTime, AOL facility, Sunnyvale, California server 205.188.185.33 iburst # nist1.aol-va.truetime.com, TrueTime, AOL facility, Virginia # Place some restrictions on this NTP "server" # restrict default ignore # Do not allow anybody restrict 127.0.0.1 mask 255.255.255.255 nopeer # Do not peer with oneself restrict 10.0.0.3 mask 255.255.255.255 nopeer restrict 192.168.0.3 mask 255.255.255.255 nopeer restrict 131.174.117.141 mask 255.255.255.255 nopeer restrict 10.0.0.0 mask 255.255.255.0 # Allow future interal clients restrict 129.6.15.28 mask 255.255.255.255 # Allow NTP servers to inform us (-: restrict 129.6.15.29 mask 255.255.255.255 restrict 132.163.4.101 mask 255.255.255.255 restrict 132.163.4.102 mask 255.255.255.255 restrict 132.163.4.103 mask 255.255.255.255 restrict 128.138.140.44 mask 255.255.255.255 restrict 192.43.244.18 mask 255.255.255.255 restrict 131.107.1.10 mask 255.255.255.255 restrict 66.243.43.21 mask 255.255.255.255 restrict 216.200.93.8 mask 255.255.255.255 restrict 208.184.49.9 mask 255.255.255.255 restrict 207.126.98.204 mask 255.255.255.255 restrict 207.200.81.113 mask 255.255.255.255 restrict 205.188.185.33 mask 255.255.255.255 #
