I observed the same bug in Centos 7, 2 instances of ntpd were created on system boot, ie:
# ps -ef | grep ntp ntp 619 1 0 15:57 ? 00:00:00 /usr/sbin/ntpd -u ntp:ntp -g root 633 619 0 15:57 ? 00:00:00 /usr/sbin/ntpd -u ntp:ntp -g And it produced these errors in the log: 9 Sep 15:57:23 ntpd[619]: process_private: failed auth mod_okay 0 9 Sep 15:57:23 ntpd[633]: ntp_intres.request: permission denied What's surprising, when you restart the service after the system has booted (ie. systemctl restart ntpd), the problem is gone. I had this ntp.conf config: restrict default kod nomodify notrap nopeer So I had to add this line, and now the service starts correctly on system boot: restrict 127.0.0.1 For IPv6 you probably need this as well: restrict -6 default kod nomodify notrap nopeer restrict -6 ::1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/50406 Title: Two instances of ntpd are launched, only one is stopped by the init script To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/50406/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
