I'm still having problems with this on 14.04. After the default installation, I installed dnsmasq and DNS stopped working until system restart.
Now it's only working for a few seconds after each network-manager restart! If I comment out #dns=dnsmasq in NetworkManager.conf, then everything is fine again. For the 500+ schools that we're supporting here, we'll just continue commenting out #dns=dnsmasq because it doesn't cooperate with the regular dnsmasq installation, but if you want me to provide more info to troubleshoot this issue, I'd be glad to. I'm attaching the output of nm-tool. My effective dnsmasq.conf is: $ egrep -rv '^#|^$' /etc/dnsmasq.* /etc/dnsmasq.d/network-manager:bind-interfaces /etc/dnsmasq.d/ltsp-server-dnsmasq.conf:dhcp-range=10.160.67.0,proxy /etc/dnsmasq.d/ltsp-server-dnsmasq.conf:dhcp-range=10.161.254.0,proxy /etc/dnsmasq.d/ltsp-server-dnsmasq.conf:dhcp-range=192.168.67.20,192.168.67.250,8h /etc/dnsmasq.d/ltsp-server-dnsmasq.conf:enable-tftp /etc/dnsmasq.d/ltsp-server-dnsmasq.conf:tftp-root=/var/lib/tftpboot/ /etc/dnsmasq.d/ltsp-server-dnsmasq.conf:dhcp-option=17,/opt/ltsp/i386 /etc/dnsmasq.d/ltsp-server-dnsmasq.conf:dhcp-vendorclass=etherboot,Etherboot /etc/dnsmasq.d/ltsp-server-dnsmasq.conf:dhcp-vendorclass=pxe,PXEClient /etc/dnsmasq.d/ltsp-server-dnsmasq.conf:dhcp-vendorclass=ltsp,"Linux ipconfig" /etc/dnsmasq.d/ltsp-server-dnsmasq.conf:dhcp-boot=net:pxe,/ltsp/i386/pxelinux.0 /etc/dnsmasq.d/ltsp-server-dnsmasq.conf:dhcp-boot=net:etherboot,/ltsp/i386/nbi.img /etc/dnsmasq.d/ltsp-server-dnsmasq.conf:dhcp-boot=net:ltsp,/ltsp/i386/lts.conf /etc/dnsmasq.d/ltsp-server-dnsmasq.conf:dhcp-option=vendor:pxe,6,2b /etc/dnsmasq.d/ltsp-server-dnsmasq.conf:dhcp-no-override ** Attachment added: "nm-tool" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/959037/+attachment/3914785/+files/nm-tool -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
