NTP Issues

[cholzhauer]

My 5000 time slowly drifts, and I assume this is why:

Code: [Select]

17 Nov 00:15:19 ntpdate[7758]: no server suitable for synchronization found
NTP_SERVER="192.168.201.10"
17 Nov 00:15:23 ntpdate[7769]: no server suitable for synchronization found
NTP_SERVER="192.168.201.10"

The target is a 2012 R2 DC that accepts NTP requests.  I don't see much in the way of configuration on the phone system...what am I missing?

ssh into the controller and verify you can ping that address to check your routing, assuming you can there isn't much for configuration in the 5000, try using an alternate like: pool.ntp.org or one more specific to your location like us.pool.ntp.org (remember to have DNS setup correctly in the 5000 as well)

Anytime you go in and change the NTP address, it will attempt a sync so you can change it and go into the logs and look.

Found it...firewall issue.

Thanks for pointing me in the right direction   

(Had to allow udp/123 to my NTP server)
