[Bug 1042275] Re: dnsmasq updating resolvconf when it's not configured to do DNS
The bug (in the network-manager package) is that /etc/dnsmasq.d/network- manager contains except-interface=lo despite the fact that network-manager was changed not to listen on lo's IP address (127.0.0.1) any more. Here's the changelog entry announcing this change. network-manager (0.9.6.0-0ubuntu4) quantal; urgency=low * debian/patches/dns-dnsmasq-interface-and-dbus-path.patch: set the address dnsmasq (and bind) plugins should listen on for DNS resolution to 127.0.1.1, as opposed to 127.0.0.1 to avoid conflicts with other instances that might need to run on the system with that address. [...] -- Mathieu Trudel-Lapierre mathieu...@ubuntu.com Tue, 21 Aug 2012 11:45:46 -0400 If the aforementioned line is commented out #except-interface=lo then name service works, with the standalone dnsmasq listening on 127.0.0.1 and forwarding to 127.0.1.1. @Submitter: please use this workaround for now. Assuming you want to use standalone dnsmasq, remember to set /etc/default/dnsmasq ENABLED back to 1.

[Bug 1042275] Re: dnsmasq updating resolvconf when it's not configured to do DNS
The issue seems to be that with its current configuration (and including bind-interfaces, and except-interface=lo), dnsmasq tries to update DNS via resolvconf which adds a file under /run/resolvconf/interface/lo.dnsmasq. That file contains 'nameserver 127.0.0.1', which is absolutely incorrect given the configuration, at least because of except-interface. This nameserver configuration in resolvconf appears to take precedence over the NetworkManager provided configuration (nameserver 127.0.1.1) also running dnsmasq. ** Changed in: dnsmasq (Ubuntu) Status: New = Confirmed ** Changed in: dnsmasq (Ubuntu) Importance: Undecided = Medium ** Changed in: dnsmasq (Ubuntu) Assignee: (unassigned) = Mathieu Trudel-Lapierre (mathieu-tl) -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/1042275 Title: dnsmasq updating resolvconf when it's not configured to do DNS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1042275/+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
