Question: Why did everything work on your machine when standalone dnsmasq wasn't in bind-interfaces mode but /etc/NM/NM.conf contained "dns=dnsmasq"?
Hypothesis: Standalone dnsmasq started first; network-manager second. NM tried to start NM-dnsmasq but this failed because of the address conflict and NM fell back to non-dnsmasq mode, which works fine. If this hypothesis is correct then there may be lines in the syslog that look like this: [date] [hostname] NetworkManager[pid]: <info> DNS: starting dnsmasq... [date] [hostname] dnsmasq[pid]: failed to create listening socket for 127.0.1.1: Address already in use -- 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: NM-controlled dnsmasq prevents other DNS servers from starting Status in “djbdns” package in Ubuntu: Confirmed Status in “dnsmasq” package in Ubuntu: Fix Released Status in “network-manager” package in Ubuntu: Fix Released Status in “pdns-recursor” package in Ubuntu: Invalid Status in “pdnsd” package in Ubuntu: Invalid Status in “djbdns” source package in Precise: Confirmed Status in “dnsmasq” source package in Precise: Triaged Status in “network-manager” source package in Precise: Triaged Status in “pdns-recursor” source package in Precise: Invalid Status in “pdnsd” source package in Precise: Invalid 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.
