disabling systemd-resolved the proper way and remove cloudflare dns

Happy new year everyone,

So I really do not like the stub-resolver in Debian/Armbian , and I do not like forwarding any DNS request to any 3rd party in general. After some searching I found this: https://www.turek.dev/posts/disable-systemd-resolved-cleanly/ . Since we are on Armbian we need also remove the 00-armbian-default-dns.conf which points to cloudflare's 1.0.0.1 .

1. We probably do not need this, but just in case someone does not have it.

sudo mkdir -p /etc/systemd/resolved.conf.d/

2. We set the DNS Stub Listener to no and remove the comment from the line if applicable:

sudo sed -i '/DNSStubListener=/s/^#//;s/=.*/=no/' /etc/systemd/resolved.conf

3. We create the needed symlinks, if applicable.

sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf

4. We remove the CloudFlare default DNS
 

sudo rm /etc/systemd/resolved.conf.d/00-armbian-default-dns.conf

5. Then we restart the service:

sudo systemctl restart systemd-resolved

Now I get my router IP as DNS resolver, which is what I like:

$ cat /etc/resolv.conf
# This is /run/systemd/resolve/resolv.conf managed by man:systemd-resolved(8).
# Do not edit.
#
# This file might be symlinked as /etc/resolv.conf. If you're looking at
# /etc/resolv.conf and seeing this text, you have followed the symlink.
#
# This is a dynamic resolv.conf file for connecting local clients directly to
# all known uplink DNS servers. This file lists all configured search domains.
#
# Third party programs should typically not access this file directly, but only
# through the symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a
# different way, replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.
