Hello, Posting in response to the old thread in ubuntu-devel titled "ANN: DNS resolver changes in yakkety", but since that thread is several months old, thought I'd start a new one.
Since upgrading to yakkety, I've noticed the following issues seemingly related to (a partial?) switch to systemd-resolved for DNS: 1) The first issue I noticed was that when connected to an openvpn VPN, firefox stopped being able to resolve DNS entries from the VPN's DNS server, while command line tools (host/ping) worked fine. Traced this down to two things, both seemingly related to my former use of resolvconf not fully migrating over to use systemd-resolved: a) Had to change my .ovpn file to point to /etc/openvpn/update-systemd-resolved instead of /etc/openvpn/update-resolv-conf b) Had to change my /etc/resolv.conf to point to /lib/systemd/resolv.conf instead of /run/resolvconf/resolv.conf Reading the documentation, it appears that systemd-resolved should have been reading from the resolvconf managed /etc/resolv.conf, but that appears to not have been happening? 2) After a suspend/resume cycle, DNS queries stopped working unless I restarted network-manager: https://bugs.launchpad.net/ ubuntu/+source/network-manager/+bug/1629620 a) After doing the fixes for problem #1, this appears to be working better now 3) Steam was unable to see the network: https://bugs.launchpad.net/ ubuntu/+source/steam/+bug/1631980 a) After manually installing libnss-resolve:i386, this is now resolved, but should this package have been installed automatically when libnss-resolve:amd64 was installed? 4) Virtualbox hosted windows VM unable to see the network when in NAT mode: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1632084 a) this is still unresolved Anyways, assuming there's eventually a fix found for #4, my real question is not so much that there were bugs, but rather are there still changes that should be made to make the solution for these issues more automatic (ie, automatically apply 1.b and 3.a)? Or at least to notify the user more loudly that their configuration is not fully supported? Thanks, -Joe
