Creating a keyfile Connection Profile Using the Network Connection Editor GUI

If not already installed, install the nm-connection-editor package. 

sudo dnf install -y nm-connection-editor
  1. Start the editor:
    sudo nm-connection-editor

    The editor detects the network devices that are on the system and lists them and their current states:

    Figure 2-1 Network Connections


    The figure shows the Network Connections editor and a list of the network devices that are on the system.
  2. To add or remove a connection, use the plus (+) or minus (-) buttons at the bottom of the editor window.

    If you add a connection, a window that prompts you for the connection type opens. Select a type, such as Ethernet, from the drop down list, then click Create. The Interface Editor window opens.

    Note:

    The same window opens if you edit an existing connection.

    Figure 2-2 Interface Editor


    The figure shows the window for editing an interface. It consists of fields that are grouped on different window tabs, through which you can enter the necessary information to configure the interface.
  3. Click each tab as needed and enter the required information about the interface.
  4. Click Save after you have completed the configuration.
    You must specify all the required information. Otherwise, the settings can't be saved and the editor's background terminal window would display messages that indicate the errors.
