> The following patch fixes the problem by *not* replacing ntp servers with an address beginning with "127."
No, it doesn't. It masks the problem by removing only servers with a name or address that starts with something other than a '1', followed by something other than a '2', followed by something other than a '7', followed by a dot. For example, with your patch, the following entries are no longer removed: server 0.ubuntu.pool.ntp.org server 1.ubuntu.pool.ntp.org server 2.ubuntu.pool.ntp.org server 3.ubuntu.pool.ntp.org server 127.1.2.3 server clock-1.cs.cmu.edu ... but this is: server ntp.ubuntu.com Unfortunately, this means that several of the server entries in the default /etc/ntp.conf are no longer removed. As a result, an unmodified machine booting on a network where DHCP provides a list of local NTP servers gets the local servers plus four from pool.ntp.org. A better answer here would be to find a proper solution to #374896, such that locally-added entries can be retained when desired (and only then!), and use that for refclock entries (127.*) as well. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/575458 Title: /etc/dhcp3/dhclient-exit-hooks.d/ntp breaks local NTP server (patch) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/575458/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
