[chrony-users] Re: Restarting the chrony service brakes chrony

[Uwe Fechner <uwe.fechner@xxxxxxxxxx>]

This is my configuration:

Start script:

[/etc/init.d]$ cat chrony

#!/bin/sh

#

# Start chrony

[ -r /etc/default/chrony ] && . /etc/default/chrony

case "$1" in

  start)

        printf "Starting chrony: "

        chronyd $CHRONY_ARGS && echo "OK" || echo "FAIL"

        ;;

  stop)

        printf "Stopping chrony: "

        killall chronyd && echo "OK" || echo "FAIL"

        ;;

  restart|reload)

        "$0" stop

         sleep 1

        "$0" start

         ;;

  *)

        echo "Usage: $0 {start|stop|restart}"

        exit 1

esac

exit $?

The file /etc/default/chrony:

[/etc/default]$ cat chrony

CHRONY_ARGS="-s -r -f /home/user/etc/chrony.conf"

The file /home/user/etc/chrony.conf:

[~/etc]$ cat chrony.conf

pool pool.ntp.org iburst offline maxdelayratio 2

driftfile /var/lib/chrony/drift

makestep 1.0 3

rtcfile /var/lib/chrony/rtc

rtconutc

rtcautotrim 30

dumpdir /var/run/chrony

Is it allowed to stop chronyd with "killall chronyd" or is there a better way?

The system is running on 32 bit ARM and was created with buildroot.

Any help would be greatly appreciated!

I have a strange problem: When chrony is started after boot all works fine.

chronyc --version
chronyc (chrony) version 4.1 (-READLINE +SECHASH +IPV6 -DEBUG)

After 5 min:

Now I restart chrony
sudo service chrony restart
and I get after 1 min:

I mean, I can ping the time servers:
ping nts1.time.nl

Any idea why chrony stops to work after a restart of the service?

Or how to debug that further?
