Hello, I've issue with nameserver. My router DHCP DNS server point to the Pi which has IP 10.6.6.3.

But for unknown reason 1.0.0.1 keep added in the /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.

nameserver 1.0.0.1
nameserver 10.6.6.3
search .

 

I've tried to manually edit and remove it from /etc/resolv.conf but it will come back.

I'm using image from https://github.com/armbian/community/releases/download/24.8.0-trunk.495/Armbian_community_24.8.0-trunk.495_Orangepizero2w_bookworm_current_6.6.36_minimal.img.xz

network:
  version: 2
  renderer: networkd
  ethernets:
    all-eth-interfaces:
      match:
        name: "e*"
      dhcp4: yes
      link-local: [ ipv4 ]

 

Is there anything I'm missing?

Think about it

You need to adjust systemd-resolved in order to have your changes persistent

I found out that there was a file that caused this /etc/systemd/resolved.conf.d/00-armbian-default-dns.conf. After removing that, the issue solved. Now only one nameserver exist in the resolv.conf. Cheers
