[Bug 1725680] Re: DNS name resolution doesn't work on Artful
@Sebastien Well, hmmm, it is possible that #1727237 is the same bug. The wifi I was using at that time was a bit weird in regards of having a captive portal: It seemed to me that it was implemented to show a captive portal in principle when connecting to it. But while some other people around were directed to that captive portal everytime they connected to the wifi, I saw it on my devices (Android phone and the laptop where I send this report from) only at the first connection - then I regularily connected to this wifi for months(!) and the captive portal was never shown again to me! And that's the reason why I even forgot to metion it at all in this bug report. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1725680 Title: DNS name resolution doesn't work on Artful To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1725680/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Jan, were you maybe using a wifi behind a captive portal at the time? could be bug #1727237 maybe? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1725680 Title: DNS name resolution doesn't work on Artful To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1725680/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It seems Casper does not update /etc/systemd/resolved.conf then I do not really know how you get this working if booting from an untouched live 17.10 Ubuntu -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1725680 Title: DNS name resolution doesn't work on Artful To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1725680/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1725680] Re: DNS name resolution doesn't work on Artful
I was finally able to test, if I could reproduce the bug on a WPA2 encrypted private wifi network. And interestingly I couldn't - DNS resolution worked fine when booting a live session and connecting to the private network. So it is possible that the behaviour I described in this report may be some sort of corner case related to the wifi network I was using 1,5 months ago. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1725680 Title: DNS name resolution doesn't work on Artful To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1725680/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1725680] Re: DNS name resolution doesn't work on Artful
I'm PXE booting 17.10 live with Serva.
I also found that the booting image DNS is broken.
I traced the problem to Casper within the booting initrd.lz, the file
/script/casper-bottom/23networking
does not populate
/etc/systemd/resolved.conf
therefore the DNS daemon does not work.
I've added to 23networking
if [ -f /root/etc/systemd/resolved.conf ]; then
resolv=/root/etc/systemd/resolved.conf
cat > $resolv <> $resolv
[ -n "$rc_server0" ] && [ "$rc_server0" != "0.0.0.0" ] && echo
"DNS=$rc_server0" >> $resolv
[ -n "$rc_server1" ] && [ "$rc_server1" != "0.0.0.0" ] && echo
"FallbackDNS=$rc_server1" >> $resolv
[ -n "$rc_server1" ] && [ "$rc_server1" = "0.0.0.0" ] && [
"$rc_server0" != "0.0.0.0" ] && echo "FallbackDNS=$rc_server0" >> $resolv
[ -n "$rc_domain" ] && echo "Domains=${rc_domain}" >> $resolv
echo "#LLMNR=yes" >> $resolv
echo "#MulticastDNS=yes" >> $resolv
echo "#DNSSEC=no" >> $resolv
echo "#Cache=yes" >> $resolv
echo "#DNSStubListener=udp" >> $resolv
fi
and now 17.10 live PXE boots correctly with a healthy DNS
Best,
Patrick

[Bug 1725680] Re: DNS name resolution doesn't work on Artful
Yes, my wifi provides a DNS nameserver. It's adress is 192.168.44.1, and it is shown when I open System Settings --> WLAN and click on the properties of the connected network. When I manually add this DNS server to resolv.conf, DNS resolution will start working. What I'm currently using is some sort of a "public facility wifi", where anyone can connect freely to without any authentification (and without encryption). Unfortunately, this is the only network I can test ATM, so I don't know if if would be different on e.g. a WPA2-encrypted private wifi. Here is the output of the two commands: $ systemd-resolve --status Global DNSSEC NTA: 10.in-addr.arpa 16.172.in-addr.arpa 168.192.in-addr.arpa 17.172.in-addr.arpa 18.172.in-addr.arpa 19.172.in-addr.arpa 20.172.in-addr.arpa 21.172.in-addr.arpa 22.172.in-addr.arpa 23.172.in-addr.arpa 24.172.in-addr.arpa 25.172.in-addr.arpa 26.172.in-addr.arpa 27.172.in-addr.arpa 28.172.in-addr.arpa 29.172.in-addr.arpa 30.172.in-addr.arpa 31.172.in-addr.arpa corp d.f.ip6.arpa home internal intranet lan local private test Link 3 (wlp7s0) Current Scopes: DNS LLMNR/IPv4 LLMNR/IPv6 LLMNR setting: yes MulticastDNS setting: no DNSSEC setting: no DNSSEC supported: no DNS Servers: 192.168.44.1 DNS Domain: lan Link 2 (enp9s0) Current Scopes: none LLMNR setting: yes MulticastDNS setting: no DNSSEC setting: no DNSSEC supported: no -- $ sudo NetworkManager --print-config # NetworkManager configuration: /etc/NetworkManager/NetworkManager.conf (lib: 10-dns-resolved.conf, 20-connectivity-ubuntu.conf) (run: 10-globally-managed-devices.conf) (etc: default-wifi-powersave-on.conf) [main] # rc-manager=symlink # auth-polkit=true # dhcp=dhclient dns=systemd-resolved plugins=ifupdown,keyfile [connectivity] uri=http://connectivity-check.ubuntu.com/ [ifupdown] managed=false [logging] # backend=journal # audit=true [device] wifi.scan-rand-mac-address=no [connection] wifi.powersave=3 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1725680 Title: DNS name resolution doesn't work on Artful To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1725680/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
