[Touch-packages] [Bug 1823098] Re: /etc/init.d/ntp prefers DHCP over configured /etc/ntp.conf
This is still a problem, even as of focal. I ran into this today and was shocked/surprised to find ntpq -p kept showing the NTP server set in option 42 (DHCP server options), rather than what was hard-coded into /etc/ntp.conf. I absolutely had this working a few days prior! Things broke when the DHCP client on the system renegotiated its lease. The problem, in the case of the systemd unit, is that the systemd unit uses ExecStart=/usr/lib/ntp/ntp-systemd-wrapper. That wrapper is a shell script that contains: if [ -e /run/ntp.conf.dhcp ]; then NTPD_OPTS="$NTPD_OPTS -c /run/ntp.conf.dhcp" fi What populates this file is /etc/dhcp/dhclient-exit-hooks.d/ntp, which runs after DHCP client exits (so on a renew, refresh, etc.). This file is provided by the ntp package itself (per dpkg -S). There doesn't seem to be a way to short-circuit the logic in the file via any kind of override, nor in the wrapper mentioned above. This kind of problem is exactly what happens when people try to make software "smart", rather than just leaving things alone and letting sysadmins configure things properly. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/1823098 Title: /etc/init.d/ntp prefers DHCP over configured /etc/ntp.conf Status in cloud-images: New Status in ntp package in Ubuntu: New Status in ntp source package in Xenial: New Bug description: Hi, On a few instances in a public cloud, mostly seen in GCE, ntp seems incorrectly set up with: | ubuntu@juju-453c71-0:~$ ntpq -pn | remote refid st t when poll reach delay offset jitter | == | *169.254.169.254 71.79.79.71 2 u 737 1024 3770.6570.136 0.147 We have /etc/ntp.conf configured to use ntp.ubuntu.com as a 'pool' host.
