changing DNS Configuration

Hi Linux gurus,

I'm having a problem with Linux with DNS Configuration:

been using fedora, win10 2019 server, win 10 enterprise.

it is only fedora and kali
ok so when I type in nmcli I get my dns configuration as:

servers: 192.168.0.1
domains: ht.home
interface: eth0

it should be
servers: 172.16.1.5 172.16.1.1
domains:example.com
domains: ht.home

How can I change this?

Thank you!

#1 is 192.168.0.1 your router? It may be picking that up via DHCP.

#2 Check your network settings. There should be a tab there where you can change the DNS settings.

There may be a more detailed Fedora answer, but I no longer run Fedora so I will wait for that input from someone current on Fedora settings.

Thank you for replying back I will have a look at the network settings and see but doing some research online do I have to change the /etc/resolve.conf file as well?

This is what you can do.

First, find your connection:

# nmcli connection show
NAME                UUID                                  TYPE      DEVICE 
Wired connection 1  dcf077fb-9f98-3f78-b449-9d6e4136a6ad  ethernet  enp0s3

Check your current values. For example, to determine which domain searches were set up, do the following:

# nmcli connection show 'Wired connection 1' | grep dns-search
ipv4.dns-search:                        --
ipv6.dns-search:                        --

If you're hosting a DNS server on this system, it's best to keep the IP address static. Assuming your IP address is 192.168.122.36, I'll do the follows:

# nmcli connection modify 'Wired connection 1' ipv4.addresses 192.168.122.36/24
# nmcli connection modify 'Wired connection 1' ipv4.gateway 192.168.122.1
# nmcli connection modify 'Wired connection 1' ipv4.dns 192.168.122.36,8.8.8.8,8.8.4.4
# nmcli connection modify 'Wired connection 1' ipv4.dns-search example.com,ht.home
# nmcli connection modify 'Wired connection 1' ipv4.method manual
# nmcli connection down 'Wired connection 1'
# nmcli connection up 'Wired connection 1'

Then my nmcli output will be something like this:

# nmcli
...
...
DNS configuration:
        servers: 192.168.122.36 8.8.8.8 8.8.4.4
        domains: example.com ht.home
        interface: enp0s3

If you have menu driven settings, those change the files that are scanned for the system to BUILD the /etc/resolv.conf file.

I rather miss the days when we managed all of that in flat files manually, but nearly all systems automate that now and will override anything you do manually on the next boot.

If the distribution menu system does not contain a section for setting those things (generally in the interface settings) then the network app (NetworkManager is most common) will be used for settings those things.

Thank you very much everyone for the feedback as I followed your advised and was able to fix the issue!

Great! You might then want to mark this thread SOLVED.
