/etc/resolv.conf how to get just two entries

[dolphs]

Hello,

 

My spare R4S is currently running the Rolling releases with Armbian Linux v6.12 Trixie image 

It seems /etc/resolved.conf got filled by at least

• /etc/systemd/resolved.conf  [ global ]
• /etc/netplan/armbian.yaml  [ per link/ ethernets: ]

 

 

However I miss from which script the IPv6 nameservers are gathered and added as currently /etc/resolv.conf shows something like this and Iike to have just the ones from [ global ]:

( Please note I removed nameservers from the yaml file already )

 

# operation for /etc/resolv.conf.

nameserver 127.0.0.1
nameserver ::1
nameserver fda8:5894:4e78:0:xxxx:xxxx:xxxx:xxxx
# Too many DNS servers configured, the following entries may be ignored.
nameserver 2001:1c00:2a02:ba00:xxxx:xxxx:xxxx:xxxx
nameserver fda8:5894:4e78:0:xxxx:xxxx:xxxx:xxxx
nameserver 2001:1c00:2a02:ba00:xxxx:xxxx:xxxx:xxxx
search .

Aiming for just the localhost nameservers in resolv.conf as unbound and pihole ( +wireguard ) will be running on the SBC only ... 

 

Hoping one can guide me as I could not find it from the Networking - Armbian Documentation

TiA!

ah I see default is:

 

nameserver 127.0.0.53
options edns0 trust-ad
search .

 

so it must be related then to /etc/systemd/resolved.conf ( DNSStubListener )

 

Same question applies, would like to limit this to DNS=127.0.0.1 ::1 ( for now )
