ntpd kernel reports TIME_ERROR: 0x2041: Clock Unsynchronized
 

Running Slack64-current witn latest Plasma5. Since installing the updates this morning I have been getting an error in the ntpd log file -

I rebuilt ntp from source but the error persists. Is anyone else seeing this? If so have you found any fixes? Thanks in advance

Do the obvious. Run to check libraries and post the active lines of the conf file. You can skip or snip all the ones with hashes.

Same problem!
The ldd command does not display anything and the configuration file is unchanged.

The ldd command shows nothing

root@missi:~$ ldd /usr/sbin/ntpd |grep found
root@missi:~$



.conf file with most # snipped (this file has worked, unchanged for a very long time - even this morning before the ntp update)

It's only an info message that the clock was unsynchronized (TIME_ERROR: 0x2041). Command 'ntptime' would have told you "status 0x2041 (PLL,UNSYNC,NANO)". And after a few minutes 'ntptime' would have said "status 0x2001 (PLL,NANO)" when the clock got sync.

There's a comment in ntpd/ntp_loopfilter.c, at line 403:

Actually, I just built the latest kernel of the day, 4.14.65 and the error has changed -

ntptime now gives -

an error. Seems to be dependent on the kernel version in use.

Wait a few minutes and check ntptime again.

Did that and now it seems to be OK

root@missi:~$ ntptime

Thanks for your responses and for pointing out that bit at line 403. All sees copacetic again.

adjtimex returned TIME_ERROR: No such file or directory
 

Hi

I am trying to run ntp in a container and i am able to communicate with ntp server . but my adjtimex is not working . I was bit confused where it was going wrong and i am very much new to the ntp concept i am givng you the output i received and your post helped me some what but i want to know for sure if it is a serious error to be considere
below is my ouptput

creating new /usr/local/var/db/ntpd.drift

Hi, welcome to LQ.

You solved this before someone answered you. Please post how for the record, as people search these threads.

yeah because I just searched this very same topic and found no solution in here to help me fix my issue.. not cool OP... soooo Not cool.. :tisk:

I object to your choice of smiley. The answers here are to real problems posted by volunteers. If nobody asked the question, there won't be an answer, meaning nobody else who has had difficulty ever posted here.

Apologies, no idea why I had marked that as solved so long ago. I did a great deal of searching back then and found no joy. I still get the same error but, on the bright side it does not seem to be a serious problem. Will remove the solved status.
