1) Install precise-desktop-i386.iso to some-pc. 2) Install dnsmasq. Fails to start. OK, annoying but let's see if the problem goes away after reboot. 3) Reboot. Try to `dig @some-pc ubuntu.com` from *another* PC. Here's the problem. It *sometimes* works. The "caching resolver" implementation introduced a race condition. So if the nm-spawned dnsmasq starts first, then the dnsmasq package is broken, and doesn't fulfill its stated goal to "provide DNS to a small network" out of the box and without manual editing of nm conffiles. If the real dnsmasq starts first, then the "caching resolver" is broken instead. Because of time constrains, I think that checking if [ -d /etc/dnsmasq.d ] before spawning dnsmasq from nm, would satisfy most of dnsmasq users. I don't think there are many users that want to keep the nm-spawned dnsmasq when they install the real one. Maybe something similar can be done for bind too. In the future, maybe the "caching resolver" implementation can start using /etc/dnsmasq.d itself, along with the KVM-spawned instances too, so that people only have one dnsmasq instance instead of multiple ones? (The reason we're using the desktop iso instead of the server one, is that we need a desktop environment in our servers for our LTSP thin clients, and because teachers work on our servers, they're not headless). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/959037 Title: Don't start local resolver if a DNS server is installed Status in “network-manager” package in Ubuntu: Triaged Bug description: As described in https://blueprints.launchpad.net/ubuntu/+spec/foundations-p-dns- resolving, network manager now starts a dnsmasq instance for local DNS resolving. That breaks the default bind9 and dnsmasq installations, for people that actually want to install a DNS server. Having to manually comment out "#dns=dnsmasq" in /etc/NetworkManager/NetworkManager.conf doesn't sound good, and if it stays that way, it should be moved to the bind9 and dnsmasq postinst scripts. Please make network-manager smarter so that it checks if bind9 or dnsmasq are installed, so that it doesn't start the local resolver in that case.
