Hi all,
Today I upgraded my kernel form 6.0.16 to 6.0.18 on a F37 system. After rebooting no nameservers are found at the end of /run/systemd/resoilve/resolv.conf.
I found 2 ways to get the name resolve work again:
-reboot in kernel 6.0.16
-Change the internet adapter configuration from DHCP to Manual (and inserting the same info as before)
This looks to me to be a bug. (or am I wrong?)
I have check two systems both on 6.0.16-300.fc37.x86_64
systemd.networkd no issue. the nameserver is the one published by my
DHCP server (also Fedora).
NetworkManager no issue. the nameserver is the one published by my DHCP
server (also Fedora).
Both use systemd.resolved and resolvectl reports the correct settings.
For example:
$ resolvectl
Global
Protocols: LLMNR=resolve -mDNS -DNSOverTLS DNSSEC=no/unsupported
resolv.conf mode: stub
Link 2 (enp2s0)
Current Scopes: DNS LLMNR/IPv4 LLMNR/IPv6
Protocols: +DefaultRoute +LLMNR -mDNS -DNSOverTLS
DNSSEC=no/unsupported
Current DNS Server: 172.16.2.254
DNS Servers: 172.16.2.254
DNS Domain: chelsea.private
Link 3 (wlp3s0)
Current Scopes: none
Protocols: -DefaultRoute +LLMNR -mDNS -DNSOverTLS
DNSSEC=no/unsupported
Check the logs from network manager for clues.
My router/dns-server/dhcpd is 172.16.2.154
I have this message on my NetworkManager system:
$ journalctl -b 0 -g 172.16.2.254
2023-01-06T17:56:25+0000 systemd-resolved[815]: enp2s0: Bus client set
DNS server list to: 172.16.2.254
