NTP not Sync to Window Domain Controller

Post by jtao387 » 2017/07/25 20:13:16

Hi, I have two Windows DC and both host as Time Server for clients to sync to... For some reason my CentOS 6.4 (Final) not able to sync, and I have checked all setting are correct (unless i over sight)... I have ran ntpq -p and -q server_IP all came back with results, but when i execute date it is 3 minutes off from DC... I can stop the service and ran ntpq -q command to sync then start the service again it'll sync, but this doesn't help fixing the problem and which I can't find... Can someone help??? Any ideas!!! Thx,

Please don't run CentOS 6.4. It's ancient and buggy and riddled with security vulnerabilities. The current CentOS 6 is 6,9 and is just a yum update away. Your system is more than 4 years out of date and there have been numerous high severity remotely exploitable security problems discovered and fixed in that time.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.

Ok, understood... Currently it will be difficult to get it change since we have other application running... Do you know if there is a fix for NTP issue if there is any, or is there a configuration I should check against??? Thx,

So what does ntpq -pn output? If you have recently restarted ntpd, please wait at least 10 minutes before issuing that ntpq command to allow ntpd to synchronize properly first. What do you have in /etc/ntp.conf and /etc/sysconfig/ntpd ?
