關於NTP

文章ykleu » 週三 4月 09, 2003 10:40 am

關於NTP部分其實國內已有國家實驗室級的原子鐘可供對時,
以下是時間網站的網址:

以下是我個人的ntp.conf內設定的server提供作參考:

server 210.59.157.40 prefer # tick.stdtime.gov.tw (nts-100)
server 210.59.157.41 prefer # tock.stdtime.gov.tw (nts-100)
server 202.39.157.151 prefer # time.chttl.com.tw (nts-100)
server 210.59.157.10 # time.stdtim.gov.tw (Dec alpha, startum 2)
server 210.59.157.30 # clock.stdtime.gov.tw(FreeBSD 2.2, startum 2)

以上設定便是參考時間網站內的設定而來。

我曾經參考ntp網站的資料做過時間校時誤差的追蹤,
的確是以國內的server為佳,在時間的連線很平均,
如果是國外的server的話,那連線便會受到網路環境的影響而有較劇烈的起伏變化,因此建議還是以國內的官方ntp server作為校時的來源。

順帶一提,以上server便是台灣官方的對時來源,舉凡電話裡的117與電視上的對時等都是參考上述server而來。

謝謝, 不過ntp server似乎沒有做HA或round-robin load balance,
以至於xxx.stdtime.gov.tw常常會有某一台連不上,
這部分你是寫shell script去解決, 直到找到可用的ntp server為止,
還是如何處理?

附帶問一下, ntpd.conf裡面定義多台ntp server, 是否ntpd會依序去找到可用的ntp server?
