I'm now questioning if it is at all sensible to use EDNS by default. It seems like the fallback should be widened for all NXDOMAIN lookups.
I've validated, that lookups fail, when DNSSEC enabled (however with a SERVFAIL, rather than NXDOMAIN). Note DNSSEC is not enabled by default. -- 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/1766969 Title: DNS cannot be resolved in Hotel Hotspot Status in systemd package in Ubuntu: Confirmed Bug description: I was asked to create a new bug for this in https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1727237 as it seems to be a different issue. I have installed the nightly image of Kubuntu Bionic from 25th of April. There systemd is in version 237-3ubuntu10. When connecting to the wifi hotspot in my hotel (Quality Hotel Augsburg) I cannot open the hotspot landing page that should give me access to the WIFI. With Windows and on an Iphone it's working. For the following distributions I can confirm it not working: Kubuntu 17.10 Kubuntu 18.04 (nightly image 25th of April 2018) The logs were taken on 18.04. Workaround: sudo systemctl disable systemd-resolved.service sudo service systemd-resolved stop sudo rm /etc/resolv.conf sudo nano /etc/NetworkManager/NetworkManager.conf >> add "dns=default" under [main] sudo service network-manager restart Then I can connect to the WIFI and I see the login page in Firefox. To capture some data I did the following: - connect to Hotspot - enter golem.de Case 1: Fresh default Kubuntu install With a default Kubuntu install it does not work. I can connect to the WIFI and get IP and DNS from DHCP but I cannot resolve any hostname. When trying to open the router ip directly in the browser it forwards to hotsplots.de which cannot be resolved. Case 2: With aforementioned Workaround I connect to the wifi, I open firefox and the login page shows up (if I havent been connected yet. In the capture I already was able to connect to the hotspot which allows immediately to connect to the webpage) PS: I'll be in this hotel till Friday 27th if more information are required.
