NTP doesn't work - Dzintars Bergs - 14th Mar, 2018 10:35 PM

Any ideas why NTP isn't working? NTPD service is running. I cant find any ntp related logs in /var/log.
All latest updates are installed, running on Pi2.

/etc/ntp.conf:

Terminal

# /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help

driftfile /var/lib/ntp/ntp.drift

# Enable this if you want statistics to be logged.
#statsdir /var/log/ntpstats/

filegen loopstats file loopstats type day enable

# You do need to talk to an NTP server or two (or three).

# pick a different set every time it starts up. Please consider joining the

ntpq -p

Oops, can you ping the servers ({0,1,2,3}.debian.pool.ntp.org) ?

RE: NTP doesn't work - Dzintars Bergs - 15th Mar, 2018 05:46 AM

I can ping all of them

RE: NTP doesn't work - Nachteule - 15th Mar, 2018 05:57 AM

Ok, so next question(s):

Did NTP ever work?

Maybe you have firewall that blocks ntp (in and/or out) packages

I've already read in a different forum (different OS), that there are providers blocking ntp packages and forcing clients to use their own ntp server

RE: NTP doesn't work - Dzintars Bergs - 15th Mar, 2018 06:07 AM

It worked before. Guess I have to check my firewall. Thaks for help!

Is the ntp daemon running ?

Code:

sudo status ntp

If not, you can try start here up with:

Code:

sudo start ntp

And check below ones :

Code:

sudo status ntp

Code:

ntpq -p

Code:

sudo zcat /var/log/upstart/ntp.log.1.gz

RE: NTP doesn't work - Dzintars Bergs - 19th Mar, 2018 05:23 AM

NTP service is running, that's not the problem.

Upstart log contains only records like those:

And you don't have messages like this in ntp.log?

Sounds for me that ntp never has been started

Could you please run commands as follows:

Code:

sudo stop ntp

sudo rm -f /var/log/upstart/ntp.log

sudo start ntp

sudo cat /var/log/upstart/ntp.log

The output should look like this

Terminal

stop dosen't work for me

Terminal

I tried with init.d, bet after that upstart log was empty

Sorry to jump in here, but those last 2 lines in your upstart log I have seen here too.....It started about 2 months ago and I get an email every night with 2 lines like this.....

Terminal

22 Mar 00:09:02 ntpd[12642]: restrict: ignoring line 37, mask '::' unusable.
22 Mar 00:09:02 ntpd[12642]: unable to bind to wildcard address 0.0.0.0 - another process may be running - EXITING

Happens on all Xbian pi using RTC and updating via the NTP servers nightly.

I noticed that the "....mask '::'" bit is also in Nachteules log, but not the failed binding, so maybe a clue here? Huh
