I attached the output of systemd-resolve --status in both cases. There is no difference. In both cases it says the DNS server is 192.168.0.2 (our local resolver), although it seems it is using another, external DNS server after a while.
Indeed the cache seems to be flushed when changing networking (e.g. turning ethernet off and back on through Gnome). Thus resolving works correctly for a while after changing networking. But after a few dozen seconds, it starts failing (ie. returning our public IP, as if it was using an external DNS server) again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1716976 Title: DNS resolver silently switches to an unknown DNS server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1716976/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
