[Bug 1758775] Re: DHCP-received NTP servers override the configuration of the NTP charm
Even with removing 'ntp-servers' from /etc/dhcp/dhclient.conf, /var/lib/ntp/ntp.conf.dhcp is written out. Steps to reproduce: Current: | ubuntu@juju-dca1e3-12:~$ ls -la /var/lib/ntp/ntp.conf.dhcp | -rw-r--r-- 1 ntp ntp 2804 Feb 23 2018 /var/lib/ntp/ntp.conf.dhcp Update removing 'ntp-servers': | ubuntu@juju-dca1e3-12:~$ sudo vi /etc/dhcp/dhclient.conf | (edit edit edit) Restart networking: | ubuntu@juju-dca1e3-12:~$ sudo service networking restart Confirm dhclient restarted: | ubuntu@juju-dca1e3-12:~$ ps afxuww | grep dhcl | root 2864 0.0 0.0 16132 928 ?Ss 04:41 0:00 /sbin/dhclient -1 -v -pf /run/dhclient.ens4.pid -lf /var/lib/dhcp/dhclient.ens4.leases -I -df /var/lib/dhcp/dhclient6.ens4.leases ens4 Check timestamp / date: | ubuntu@juju-dca1e3-12:~$ ls -la /var/lib/ntp/ntp.conf.dhcp | -rw-r--r-- 1 root root 2804 Oct 28 04:41 /var/lib/ntp/ntp.conf.dhcp It's actually because ntp_servers_setup_add() in /etc/dhcp/dhclient- exit-hooks.d/ntp writes that out no matter what. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1758775 Title: DHCP-received NTP servers override the configuration of the NTP charm To manage notifications about this bug go to: https://bugs.launchpad.net/ntp-charm/+bug/1758775/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1758775] Re: DHCP-received NTP servers override the configuration of the NTP charm
I don't think this is really the same problem. The init script for NTP is designed to honour the settings provided by the DHCP client. In most cases, this is expected, but when the charm is configured, users expect the charm to manage the local settings for them without needing to override the DHCP client. I think the preferred solution would be for the charm to disable the DHCP client from modifying the NTP configuration by removing "ntp-servers" from the "request" entry in /etc/dhcp/dhclient.conf. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1758775 Title: DHCP-received NTP servers override the configuration of the NTP charm To manage notifications about this bug go to: https://bugs.launchpad.net/ntp-charm/+bug/1758775/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This is actually LP: #1823098. I don't think this is a charm problem, I mean, it could touch ntp.conf on update-status hook but that's ugly. ** Also affects: ntp (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1758775 Title: DHCP-received NTP servers override the configuration of the NTP charm To manage notifications about this bug go to: https://bugs.launchpad.net/ntp-charm/+bug/1758775/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
