Re: NTPD Errors

Do you have an NTP server configured on your controller?  What is the configuration?

Re: NTPD Errors

I totally missed that. Thanks Joseph!

Re: NTPD Errors

Can you confirm the NTP servers are reachable from the controller and correctly responding to NTP requests.

 

In the "st" column, if you have the value of "16" then this means NTP is not updating correctly. Also note that offset and disp are not returning values either.

ACMA, ACMP

Re: NTPD Errors

Turns out the authkey was wrong somehow.

 

Thanks for the help!
