    my conf file is as above and i trying to start ntp daemon and it show clock unsynchronized and i dig up bit more in that and found some frequency issue, for more clarification please look at below log.

Hi and welcome. It’s normal to see unsynchronized messages when ntpd starts up.

What does “ntpq -c peers” report after ntpd has been running for at least 10 minutes?

3

hi @elljay
after 10 min clock is in unsynchronized state, could you please suggest more specific to debug

4

Hi, please can you post the output of “ntpq -c peers” so we can see how many peers you have configured and whether they are reachable etc.

5

hello,
thank you for reply, i had configure with mine local machine as config file in above post.

Hi, just one remote server is too little for ntpd to adjust the clock and be confident that the time is right.
Ntpd needs at least 3 servers to be sure of the correct time, before setting and adjusting the clock and distributing time. With 3 servers ntpd can vote out a “false ticker”.
Segal’s Law: " A man with a watch knows what time it is. A man with two watches is never sure."

Configure 3 - 7 servers and then ntpd should stop the alert.

7

Hi,
added pool server as well as local server with prefer option, and the result is same, can you please tell more about freq. settings, as per my views it not set due to ntp_adjtime() and loop_config() then it set NSET state.

If you keep the ntpd running further, does it still report Clock Unsynchronized error time to time later on?

9

Or run “ntpq -c rv”. In the first line of the output, you should see clock_sync if the clock is synchronized. A full description of the first line of the output can be found here: http://www.eecis.udel.edu/~mills/ntp/html/decode.html#sys

10

in first 10 minute only. then get error of drift file.

So there seems to be no synchronization problem. At the start-up it is normal that the clock is not yet synchronized and that situation is reported.

The ntpd daemon may have lack of write permission to the directory /var/lib/ntp/ ?

12

hello
i had change directory path and permission and didn’t get directory error. but when i exit my time is roll over to hardware clock any view on this!

ntpd is a daemon - it’s meant to run in the background all the time.

14

Going back to the kitchen sink. What kind of hardware and OS do you have? What way do you start the ntpd and under which user id?

(1st January: Which year? 1970?)

15

i have android OS, ntpd -d -x -g command to start daemon and it set to 1st January 1970.
