[Samba] After upgrade to 4.9.4, internal DNS no longer working
Hi list,
I just upgraded my Samba AD DC to v4.9.4. Unfortunately, I can't recall
which version I had before that, I believe it must have been something
between 4.6 and 4.8.
Anyway, now that the upgrade is done, it looks like DNS is gone. Host
commands are timing out, netstat reveals that no process is listening on
:53.
Other than that, Samba is starting and working fine. I can list shares, I
can interact with the AD while I stay on localhost.
/etc/samba/smb.conf:
------------------------------------
[global]
workgroup = samdom
realm = samdom.example.com
netbios name = dc1

Any advice what I could try to get DNS running again?

[Samba] After upgrade to 4.9.4, internal DNS no longer working
Oh, that doesn't sound good... Arch Linux. I did a regular system upgrade using pacman -Syu which automatically upgrades all packages to their latest version. I have another, practically identical system and I didn't have this issue there. Though I might have had a smaller jump between versions.
