Bug Description
Regularly (= after about 15 mins of use) the systemd-resolved service stops resolving DNS names (any).
Configuration:
Two domains defined - one internal, one for external services
DNS server does not provide DNSSEC services
Both domains are in the search path (served by DHCP)
Effect:
Clients refuse to resolve internal domain servers (short or FQDN) after about 15 mins.
Workaround:
from the client CLI
sudo systemctl restart systemd-
Background:
A Github error (https:/
I found discussions about "the correct way" DNS works (with only one domain).
Happens exclusively on Ubuntu clients (Windows, Mac and Fedora worked fine).
