Bug description:
[impact]
systemd-resolved emits a disturbingly large amount of NXDOMAIN log
messages that do not actually indicate any real problem
[test case]
see original description, or look at any log from any recent Ubuntu
system, or search google for endless complaints about NXDOMAIN
messages logged by Ubuntu
[regression potential]
any regression would likely be isolated to systemd-resolved handling
of a NXDOMAIN response from its upstream nameserver, including
possibly failing to resolve a hostname or delays in resolving
hostnames
[scope]
this is needed for all releases; the patch is not upstream, but
carried by Ubuntu
[original description]
I normally don't like this, but it's a one-character change so it's
easier to start with the solution:
diff -u -r1.1 /usr/lib/NetworkManager/conf.d/20-connectivity-ubuntu.conf
--- /usr/lib/NetworkManager/conf.d/20-connectivity-ubuntu.conf
+++ /usr/lib/NetworkManager/conf.d/20-connectivity-ubuntu.conf
@@ -1,2 +1,2 @@
[connectivity]
-uri=http://connectivity-check.ubuntu.com/
+uri=http://connectivity-check.ubuntu.com./
Making this name absolute instead of relative avoids spurious
resolutions of "connectivity-check.ubuntu.com.your_domain." This
removes a fair amount of NXDOMAIN error noise in journalctl.
Observing the issue and the fix requires 3 terminals:
1. tcpdump -i any 'port domain'
2. journalctl --boot -u systemd-resolved -f
3. nmcli c down "Wired connection 1"; nmcli c up "Wired connection 1"
=> observe the NXDOMAIN noise over a couple few minutes
Now make the hostname absolute with the trailing dot above and run:
systemctl reload NetworkManager
Wait 1 min for things to stabilize. Test again:
nmcli c down "Wired connection 1"; nmcli c up "Wired connection 1"
=> observe non-zero but significantly reduced NXDOMAIN noise over a couple
few minutes
Originally reported at https://askubuntu.com/a/1242611/117217
Plenty of people annoyed by NXDOMAIN warnings, just Google it.
