1.5. Network Configuration Using a Text User Interface (nmtui)
The NetworkManager text user interface (TUI) tool, nmtui, provides a text interface to configure networking by controlling NetworkManager. The tool is contained in the NetworkManager-tui package. At time of writing, it is not installed along with NetworkManager by default. To install NetworkManager-tui, issue the following command as
root:
~]# yum install NetworkManager-tui
If required, for details on how to verify that NetworkManager is running, see Section 1.4.1, “The NetworkManager Daemon”.
To start nmtui, issue a command as follows:
~]$ nmtui
The text user interface appears. To navigate, use the arrow keys or press Tab to step forwards and press Shift+Tab to step back through the options. Press Enter to select an option. The Space bar toggles the status of a check box.
The following commands are available:
If no connection name is supplied, the selection menu appears. If the connection name is supplied and correctly identified, the relevant Edit connection screen appears.nmtui editconnection-name
If no connection name is supplied, the selection menu appears. If the connection name is supplied and correctly identified, the relevant connection is activated. Any invalid command prints a usage message.nmtui connectconnection-name
At time of writing, nmtui does not support all types of connections. In particular, you cannot edit VPNs, wireless network connections using WPA Enterprise, or Ethernet connections using
802.1X.
