Maybe there is a better way to do this, but here is my situation. I need to be able to send DNS queries to multiple dns servers in parallel and use the first response I get back (so that I use the fastest/closest dns server). On 16.04 I did this by running dnsmasq with the "all-servers" option enabled. afaict, resolved doesn't have an equivalent option. The nameservers come from a supersede rule in the dhclient configuration. But on 18.04 if resolved is running, then dnsmasq uses resolved as the nameserver, which isn't what I want, but if resolved isn't running then I run into this bug and dnsmasq doesn't get any nameservers. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1745463 Title: Disabling systemd-resolved breaks dhclient resolvconf integration Status in resolvconf package in Ubuntu: Expired Status in systemd package in Ubuntu: Confirmed Bug description: To reproduce, mask resolved: sudo systemctl mask systemd-resolved.service ...then disable network-manager for ifupdown interfaces: $cat /etc/NetworkManager/NetworkManager.conf [main] plugins=ifupdown,keyfile dns=default rc-manager=resolvconf [ifupdown] managed=false [device] wifi.scan-rand-mac-address=no ...and reboot. You'll note that resolvconf integration with dhclient is now broken. Interfaces listed in /etc/network/interfaces or /etc/network/interfaces.d/* will not provide DNS configuration in /etc/resolv.conf and /run/resolvconf/interfaces/. This is because /etc/dhcp/dhclient-enter-hooks.d/resolvconf defines "make_resolv_conf()" as a valid function for the BOUND case, but /etc/dhcp/dhclient-enter-hooks.d/resolved undefines it (who's nasty now, eh?) even though resolved is masked. The file existence check in the beginning of /etc/dhcp/dhclient-enter- hooks.d/resolved should be more thorough, i.e. it should ensure that resolved is enabled, rather than simply look for the existence of /lib/systemd/systemd-resolved. This works for me: -if [ -x /lib/systemd/systemd-resolved ] ; then +if [ -x /lib/systemd/systemd-resolved ] && systemctl -q is-enabled systemd-resolved ; then Arguably, /etc/dhcp/dhclient-enter-hooks.d/resolvconf should implement a similar check, looking for /run/resolvconf/enable-updates as a condition for meddling with DNS settings. If desired, I'll file a separate bug for that package.
