我的NTPconfiguration是否正确?

我有一个远程运行的CentOS虚拟机,可以通过VPN访问。 它被设置为同步来自同一networking上的两台服务器的时间。 时间是大致正确的,但似乎是漂stream。 我对下面输出中提到的2036年的date感到担心,我应该吗?

/usr/sbin/ntpq -pcrv remote refid st t when poll reach delay offset jitter ============================================================================== 10.245.8.100 10.249.8.100 2 u 24 64 377 1.185 12124.8 29.489 10.249.8.100 .RMOT. 16 u - 1024 0 0.000 0.000 0.000 assID=0 status=c011 sync_alarm, sync_unspec, 1 event, event_restart, version="ntpd [email protected] Fri Nov 18 13:21:21 UTC 2011 (1)", processor="x86_64", system="Linux/2.6.18-308.el5", leap=11, stratum=16, precision=-20, rootdelay=0.000, rootdispersion=56.655, peer=0, refid=INIT, reftime=00000000.00000000 Thu, Feb 7 2036 6:28:16.000, poll=6, clock=d3fd6d1a.a01aab1b Fri, Sep 14 2012 9:45:14.625, state=1, offset=0.000, frequency=0.000, jitter=0.001, noise=0.001, stability=0.000, tai=0 

根据下面的build议,进一步的信息…

 sudo /usr/sbin/ntpdate 10.245.8.100 14 Sep 13:02:02 ntpdate[7766]: step time server 10.245.8.100 offset 12.212849 sec 

和ntp.conf

 restrict 127.0.0.1 restrict -6 ::1 server 10.245.8.100 server 10.249.8.100 driftfile /var/lib/ntp/drift keys /etc/ntp/keys server 10.245.8.100 restrict 10.245.8.100 server 10.249.8.100 restrict 10.249.8.100 

看起来很奇怪。

  • “stratum = 16”表示它没有同步到时间源。
  • 达到377 – ntp服务器可达。
  • 偏移12124.8 – 大不同步

尝试在开始时执行“ntpdate 10.245.8.100”作为快速同步时钟。

在configuration中禁用可能的大调整作为对错误configuration的措施? 显示你的ntpd.conf

作为第一个添加,限制规则允许同步

 # Permit time synchronization with our time source, but do not # permit the source to query or modify the service on this system. restrict default kod nomodify notrap nopeer noquery restrict -6 default kod nomodify notrap nopeer noquery # Permit all access over the loopback interface. This could # be tightened as well, but to do so would effect some of # the administrative functions. restrict 127.0.0.0 mask 255.0.0.0 restrict -6 ::1
