# # Undisciplined Local Clock. 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 # 0. 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. # # # Latest Version: # -------------- # http://www.Linux-Consulting.com/NTP # # # NTP FAQs and Commands # --------------------- # http://www.Linux-Consulting.com/NTP/NTP.Commands.txt # # # List of NTP servers # ------------------- # http://www.eecis.udel.edu/~mills/ntp/servers.html # # # Latest NTP sources # ------------------ # http://www.eecis.udel.edu/~ntp/download.html # http://www.eecis.udel.edu/~ntp/ntp_spool/ # # # Docs: Peers, Restrict, Authenticate # ----------------------------------- # http://www.ccd.bnl.gov/xntp/author-notes.html # http://www.linuxhomenetworking.com/linux-hn/ntp.htm # # # 13-Sep-01 amo Added ntp # 03-Nov-02 amo Changed to tick and tock # 22-Oct-03 amo Take out multicast # 24-Apr-04 amo Added Stats, peer versions, restrict, turn on broadcastclient # 03-Dec-04 amo Added LinuxHomeNetworking.com ntp-howto # # # # # Your NTP servers sync's up to the world ( NTPserver# cp ntp.servers.conf ntp.conf ) # Your Local PCs, sync's up to your own local NTP servers ( client# cp ntp.client.conf ntp.conf ) # # server tick.Linux-Consulting.com server tock.Linux-Consulting.com #server ntp.Linux-Consulting.com # #server ntp.your-domain.com # # server 127.127.1.0 # local clock fudge 127.127.1.0 stratum 10 # ------------------------------------- # # # specify NTP version 1 # # peer 130.43.2.2 version 1 # apple.com (running ntpd version 1) # peer 130.43.2.2 version 2 # apple.com (running xntpd version 2) # # # # # by default, don't trust and don't allow modifications # restrict default notrust nomodify # # # these guys are trusted for time, but no modifications allowed # restrict 128.8.10.1 nomodify # # # unrestricted # restrict 127.0.0.1 # # ---------------------------------------- # Don't serve time or stats or trust anyone else by default (more secure) # restrict default noquery notrust nomodify # Trust ourselves. :-) ( localhost has full access without any restrictions ) restrict 127.0.0.1 # # 13-Sep-01 amo Added log info # logconfig all logfile /var/log/xntpd # # Drift file.
