[SOLVED]Change DNS resolver - Ubuntu 22.04

Hi

Yes, I'm a noob! But please help me out here

I want to change my DNS resolver to googles

My /etc/network/interfaces look like this:

Code:

#This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5)

# Include files from /etc/network/interfaces.d:
source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

My: /etc/resolv.conf look like this:

Code:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.

nameserver 127.0.0.53

And my: resolvectl status | grep Current

Code:

root@skytower ~ # resolvectl status | grep Current
Current Scopes: DNS
Current DNS Server: 185.12.64.2

Im running Ubuntu 22.04, and my server is hosted at hetzner.com

Hope someone can help me

In /etc/network/interfaces - I have try to change

Code:

#This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5)

# Include files from /etc/network/interfaces.d:
source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

to this

Code:

## /etc/network/interfaces example Hetzner root server
# Loopback-Adapter
auto lo
iface lo inet loopback
#
# LAN interface
auto eth0
iface eth0 inet static
  # Main IP address of the server
  address 138.201.226.*
  # Netmask 255.255.255.255 (/32) independent from the
  # real subnet size (e.g. /27)
  netmask 255.255.255.255
  # explicit host route to the gateway
  gateway 138.201.226.193
  pointopoint 138.201.226.193
  dns-nameservers 8.8.8.8 8.8.4.4

# IPv6

iface eth0 inet6 static
  # one IPv6 address from assigned subnet
  address 2a01:4f8:173:****::2
  netmask 64
  gateway fe80::1
  dns-nameservers 2001:4860:4860::8888 2001:4860:4860::8844

But after a reboot it dont seams to work!

Code:

root@skytower ~ # resolvectl status | grep Current
    Current Scopes: DNS
Current DNS Server: 185.12.64.2
root@skytower ~ #

 

Okay..
I have come a stop further

Code:

sudo mkdir /etc/systemd/resolved.conf.d/
sudo nano /etc/systemd/resolved.conf.d/dns_servers.conf

Put this in the dns_servers.conf

Code:

[Resolve]
DNS=8.8.8.8 8.8.4.4 2001:4860:4860::8888 2001:4860:4860::8844
Domains=~.

Code:

sudo systemctl restart systemd-resolved

If i run: "resolvectl" - I get this output


What is Link 2??? Are these settings looking right??

 

Here we go Here is the file I have been looking for!
There was a file called: /etc/netplan/01-netcfg.yaml
I cut changed the setting for my network there, and all seems to work now.

 

Well, that's common thing to do if you read and follow Ubuntu 22.04 Minimal Server Tutorial in here to build yours.
