Title:
name resolution stops working
Status in systemd package in Ubuntu:
Confirmed
Bug description:
System: Ubuntu 17.10 beta
DNS server hosts an internal and an external domain (the internal is used for
internal purposes).
Name resolution works for a while. Every now and then, the name resolution
stops working.
This issue was reported in 17.04 but no suggestion for resolv has worked.
In 17.10 the symptoms are the same, the duration till it happens are
longer (about 1.5 days).
restarting systemd-resolved solves the issue temporarily. However,
this should not be required at all.
Happens on a fresh install
Setup:
DNS serves rsb.at and rsb.intern
Server www.rsb.at can be reached even when internal resolution fails.
Seems that the internal DNS server (the first in the line) is not queried
first.
If so, an rsb.intern address will not be found.
