[BUG] Inquiry about NTP Server Issue

[bongthu]

Component

chrony

Describe the bug

I have installed Navix version 9.5 with minimal.
The chrony package was installed and the timezone was set to KST.

However, when I checked the time with date command, the actual time is not Korean time,
When I checked the time with "timedatectl" command, the value of “System clock synchronized” is no.

Is this intended?

I used the ntp server provided by default in the RHEL OS and found that the time was correctly synchronized.
(Change the contents of the /etc/chrony.conf file "pool 2.navix.pool.ntp.org iburst" -> "pool 2.rhel.pool.ntp.org iburst")

Best Regards,
bongthu

Expected behavior

After installing the chrony package, I want the chronyd service to synchronize to KST when I run it.

To Reproduce

1. Install navix os
2. Check for installed chrony packages
3. Performing the date and timedatectl commands
4. Check "System clock synchronized: no" and Seeing KST but not the actual time

Screenshots / Live demo link

No response

Environment

OS : navix
ver : 9.5

Additional context

Confirmed:

The same issue was observed with the boot image:

It seems Naver Navix has not setup their NTP server (2.navix.pool.ntp.org) as configured, or the NTP server is down.

$ ping 2.navix.pool.ntp.org 
ping: 2.navix.pool.ntp.org: Name or service not known

$ cat /etc/chrony.conf 
# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (https://www.pool.ntp.org/join.html).
pool 2.navix.pool.ntp.org iburst

$ chronyc -n sources
MS Name/IP address         Stratum Poll Reach LastRx Last sample               
===============================================================================
$ timedatectl
               Local time: Tue 2024-12-17 10:06:57 CST
           Universal time: Tue 2024-12-17 16:06:57 UTC
                 RTC time: Tue 2024-12-17 16:06:55
                Time zone: America/Chicago (CST, -0600)
System clock synchronized: no
              NTP service: active
          RTC in local TZ: no
$ 

1. The ultimate remedy can be a highly available NTP server @2.navix.pool.ntp.org ,
2. For the time being, as @bongthu mentioned above, the temporary workaround can be setting up the alternative ntp servers into /etc/chrony.conf as below:

$ sudo vi /etc/chrony.conf 

$ systemctl restart chronyd.service
$ chronyc -n sources
MS Name/IP address         Stratum Poll Reach LastRx Last sample

@bongthu , @SeungYeop-Yang
Thank you for your report.



As metioned above, Navix NTP server (2.navix.pool.ntp.org) is not set up yet. 

We are preparing it now and we’ll share you as soon as it’s ready :)

@songhee1030 ,
Why is the status of this issue labeled as resolved?

I tested the default config after seeing this one resolved:

[sajang@vbox ~]$ head /etc/chrony.conf 
# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (https://www.pool.ntp.org/join.html).
pool 2.navix.pool.ntp.org iburst

[sajang@vbox ~]$ timedatectl
               Local time: Sat 2025-01-18 23:11:12 CST
           Universal time: Sun 2025-01-19 05:11:12 UTC
                 RTC time: Sun 2025-01-19 05:11:12
                Time zone: America/Chicago (CST, -0600)
System clock synchronized: no
              NTP service: active
          RTC in local TZ: no
[sajang@vbox ~]$
[sajang@vbox ~]$ chronyc -n sources
MS Name/IP address         Stratum Poll Reach LastRx Last sample               
===============================================================================
[sajang@vbox ~]$ 

From the above, the issue is still open, and that's not resolved yet.

@SeungYeop-Yang,
Sorry for the confusion, it's my fault; missed to change label back to 'ondev'.

NTP pool for 'navix' was activated few days ago (navix.pool.ntp.org),
but hostnames for {0,1,2,3}.navix.pool.ntp.org are not responding right now.
I was contacting the person in charge about this.

I'll keep you updated on the status :)

Thanks for the clarification. I will wait, but please don't label the issues as resolved until the resolution can be verified; let's prevent any unnecessary message churns.

[songhee1030]

Apologies for the delay in response.
There was a delay due to difficulty in reaching the person in charge.

For now, please use navix.pool.ntp.org.
The default address in Chrony 2.navix.pool.ntp.org will be provided as soon as contact is established.

Thank you for your patience and understanding.
Please feel free to reach out if you have any questions.
