System log had some odd ntp related stuff, anyone able to interpret to me?

Hello! Is anyone able to shed a light what was going on in my Mint system? I didn't notice any odd behaviour. But syslog makes me ponder that maybe everything wasn't allright? And my router seemed to have those IP:s in the UDP connection list in port 123.

Code:

Which of those messages worry you?

You do seem to have an ill-configured DNS if the names of the NTP pools can't be resolved. On the other hand, the command ntpq -pn should tell you more about NTP health.

Thanks for the reply!

Those were new lines to me in syslog and router had so many adresses in 123 port, never seen them there. So wasn't sure what was going on. However i didn't change any DNS things in system, i don't even know how And in router, i had my ISP:s DNS-servers

I see your time server contacting various internet time server, and failing to contact Ubuntu pool servers. I don't know whether the latter is worrying; probably not. The former is normal, I'd say.

Your Mint system's DNS configuration starts with /etc/resolv.conf.

EDIT: Those name resolution problems may be global. I can't resolve 3.ubuntu.pool.ntp.org right now either.

I just pinged 1.ubuntu.pool.ntp.org succesfully, and also one of the numerical IPs.
So maybe your ntp service starts before the network is fully up?

Thanks for the info!

Thanks for the reply! I hadn't change anything in the load up or internet related things in the system. Only updates could have change something.

Unfortunately i'm unable anymore do any testing on that system. I had on to-do-list to have a fresh start as it was already 2 years old installation so decided this was good moment to start on clean table as seemed things might go out of my hands and knowledge level.

However, it is interesting to know what was going on for future problems

3.ubuntu.pool.ntp.org can be resolved again. I say you are the victim of a temporary glitch.

I checked logs i had backuped. It seems something had been going on for a while in this matter i think:

On may 5 there was also in log these same things: "error resolving pool 2.ubuntu.pool.ntp.org: Name or service not known (-2)"
Also on may 10.

Then there was also these:

Code:
