Solution: I just had to create the file
I wanted to install Pi-Hole on my server and noticed that port 53 is already in use by something.
Apparently it is in use by systemd-resolved:
~$ sudo lsof -i -P -n | grep LISTEN
[...]
systemd-r 799 systemd-resolve 18u IPv4 7018 0t0 TCP 127.0.0.53:53 (LISTEN)
systemd-r 799 systemd-resolve 20u IPv4 7020 0t0 TCP 127.0.0.54:53 (LISTEN)
[...]
And the solution should be to edit /etc/systemd/resolved.conf
by changing #DNSStubListener=yes
to DNSStubListener=no
according to this post I found. But the /etc/systemd/resolved.conf
doesn’t exist on my server.
I’ve tried sudo dnf install /etc/systemd/resolved.conf
which did nothing other than telling me that systemd-resolved
is already installed of course. Rebooting also didn’t work. I don’t know what else I could try.
I’m running Fedora Server.
Is there another way to stop systemd-resolved
from listening on port 53? If not how do I fix my missing .conf
file?

The service is using the default config, which you can override by creating this file.

Yep, it might be enough to just add that file with the setting set to no and restart.
