[PROBLEM] NTP doesn't work

[Dzintars Bergs]

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/

statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable


# You do need to talk to an NTP server or two (or three).
#server ntp.your-provider.example

# pool.ntp.org maps to about 1000 low-stratum NTP servers. Your server will
# pick a different set every time it starts up. Please consider joining the
# pool: <http://www.pool.ntp.org/join.html>
pool 0.debian.pool.ntp.org iburst
pool 1.debian.pool.ntp.org iburst
pool 2.debian.pool.ntp.org iburst
pool 3.debian.pool.ntp.org iburst

# Access control configuration; see /usr/share/doc/ntp-doc/html/accopt.html for
# details. The web page <http://support.ntp.org/bin/view/Support/AccessRestrictions>
# might also be helpful.
#
# Note that "restrict" applies to both servers and clients, so a configuration
# that might be intended to block requests from certain clients could also end
# up blocking replies from your own upstream servers.

# By default, exchange time with everybody, but don't allow configuration.

No idea

What's the output of

Code:

ntpq -p

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

[Dzintars Bergs]

I can ping all of them

Terminal

root@pi2 ~ # ping 0.debian.pool.ntp.org

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

[Dzintars Bergs]

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

[Dzintars Bergs]

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?

No, only "Soliciting pool server...".

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

root@kmxbilr2 /etc/default # stop ntp

stop dosen't work for me

Terminal

root@pi2 ~ # stop ntp
stop: Unknown instance:

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

Terminal

root@pi2 ~ # /etc/init.d/ntp stop
[ ok ] Stopping NTP server: ntpd.
root@pi2 ~ # rm -f /var/log/upstart/ntp.log

cat: /var/log/upstart/ntp.log: No such file or directory

After reboot upstart log looked like this

Terminal

[Skywatch]

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?

[Skywatch]

Hmmmm.....This is what I get after running @nachteules' commands...
