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 Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/959037 Title: NM-controlled dnsmasq prevents other DNS servers from starting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/djbdns/+bug/959037/+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
