An alternative for the nmcli is the nmtui, short for Network Manager Text User Interface, the nmtui is yet another handy tool that allows you to easily configure your network interfaces in Linux distributions using a graphical display by invoking the nmtui command straight from the terminal or even putty.
To configure a network interface IPv4 address, start by invoking the nmtui tool.
$ nmtui
Select the first option ‘Edit a connection’ and hit ENTER.
Edit Network Interface Connection
Next, select the interface you want to configure and hit ENTER. In this case, the interface we are configuring is enps03.
Select Network Interface
In the next step, key in the preferred IP address and define the subnet mask, default gateway, and DNS servers as shown below.
Configure Network Connection
Once you are satisfied with your settings, scroll all the way down and hit ENTER on the ‘OK’ option.
Confirm Network Settings
This takes you back to the interfaces screen as shown below. Navigate and hit on the ‘Back’ option.
Network Interface Settings
Select ‘Activate a connection’ and then ‘OK’ and hit ENTER.
Active Network Connection
Select your interface name and then navigate to the ‘Deactivate’ option and hit ENTER.
Deactivate Network Connection
This will take you a step back whereupon you will click on the ‘Activate’ option as shown:
Active Network Connection
We’re all done now. To go back click on the ‘Back’ option and finally, press ENTER on the ‘quit’ selection.
Quit Network Configuration
Again, to verify that the network interface has acquired the IP address we have just configured, run the command:
$ ip addr show enp0s3
Confirm Network IP Address
And this concludes this article on configuring IP network connection using ‘nmtui’ graphical command-line utility on Linux. We hope you found this guide helpful.
