nmtui (Network Manager Text User Interface)
If you do not like the complicated syntax of the nmcli command line, you might like nmtui . This is a text user interface that allows you to create network connections easily.The tool is contained in the subpackage NetworkManager-tui. At time of writing, it is not installed along with NetworkManager by default. To install NetworkManager-tui, issue the following command as
1.Edit a Connection:
Use this to (re)activate a connection.
3. Set System Hostname:
When you select the option Edit Connection, you get access to a rich interface that allows you to edit most properties of network connections. After editing the connection, you need to deactivate it and activate it again. This should work automatically, but the fact is it does not.
If you like graphical user interface (GUI) tools, you are lucky. Use nmconnection-editor instead of nmtui, but be prepared that this interface offers a relatively restricted option set. It does not contain advanced options such as the options to create network team interfaces and manage network bridge interfaces.
It does, however, offer all you need to manage address configuration on a network connection. Start it by using the nm-connection-editor command, or by using the applet in the GNOME graphical interface.
