NTPの設定

Fedoraでは特に設定する必要はないようです,Vine Linuxで ntpd起動時にntpdateが実行されず,調べてみました

設定ファイル /etc/ntp.conf /etc/ntp/key ,drift ,step-ticker(server名を設定しておく) /etc/sysconfig/ntpd /etc/rc.d/init.d/ntpd /etc/rc.d/init.d/ntpd で /etc/ntp/step-ticker があれば,ntpdの起動前に ntpdate server名 を行い,次いで ntpd を実行するように書かれている

Vine Linux 4.1 の ntp.conf # 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. # server 127.127.1.0 # local clock fudge 127.127.1.0 stratum 10 # # Drift file. Put this in a directory which the daemon can write to. # No symbolic links allowed, either, since the daemon updates the file # by creating a temporary in the same directory and then rename()'ing # it to the file. # driftfile /etc/ntp/drift multicastclient # listen on default 224.0.1.1 broadcastdelay 0.008 # # Keys file. If you want to diddle your server at run time, make a # keys file (mode 600 for sure) and define the key number to be # used for making requests. # # PLEASE DO NOT USE THE DEFAULT VALUES HERE. Pick your own, or remote # systems might be able to reset your clock at will. Note also that # ntpd is started with a -A flag, disabling authentication, that # will have to be removed as well. # #keys /etc/ntp/keys server time.nrc.ca server ntp1.cmc.ec.gc.ca server ntp2.cmc.ec.gc.ca
