Ubuntu 18.04 Desktop DNS Servers

  • 772

I set DNS servers on my PC to my local DNS caching server (192.168.100.2), and 1.1.1.1, 1.0.0.1

Wired interface settings - DNS in IPv4 tab

Resolution on local DNS zone (.local) does not work. It works only when I force dig tool to use local server.

specifying server to dig in command line

Could you please help me set up a custom DNS server?

dns 18.04

  1. My system consists of Ubuntu Desktop and a lot of additional server software, like Bind, Apache, Postfix.
    I had the same problem: The configuration network configuration inputs from the GUI (settings > network) did not go into /etc/resolv.conf. Also the inputs from netplan did not got into /etc/resolv.conf. With this solution dig and nslookup work correctly.

    The symbolic link /etc/resolv.conf points actually to /run/systemd/resolve/stub-resolv.conf. After the following solution it points to /run/systemd/resolve/resolv.conf: 

    $ sudo rm /etc/resolv.conf 
$ sudo ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
