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?
Um, dnf doesn’t do anything with configuration files. It is used for packages.
I would start by trying to create that file. If that doesn’t fix it after restarting the service look into the docs. You may need to configure network manager.
It tries to install the associated package when given a path to a configuration file.
