10.5 Configuring Network Interfaces Using Graphical Interfaces


The NetworkManager service and the nmcli command are included in the NetworkManager package. The Network Connections editor is included in the nm-connection-editor package.

The NetworkManager service dynamically detects and configures network connections. You can click on the network icon in the GNOME notification area to obtain information about the status of the network interfaces and to manage network connections:

  • To enable or disable a network interface from the pull-down menu, use the On/Off toggle.

  • To display the Settings window, select Network Settings from the drop-down menu.

Figure 10.2 shows the Network Settings editor.

To edit an existing interface, select it from the list and click the gear icon. You can add a profile to any interface to provide alternate configurations that you can use at any point in time. You can equally use this window to configure a network proxy or add an enable a Virtual Private Network (VPN) connection.

To perform more complex configuration and to add additional connection types, use the Network Connections editor. This tool allows you to configure wired, wireless, mobile broadband, VPN, Digital Subscriber Link (DSL), and virtual (bond, bridge, team, and VLAN) interfaces. You can open this window by using the nm-connection-editor command. Figure 10.2 shows the Network Connections editor.

To create a new network interface, click the + icon, select the type of interface (hardware, virtual, or VPN) and click Create. To edit an existing interface, select it from the list and click the gear icon. To remove a selected interface, click the - icon.

You can also use the nmcli command to manage network connections through NetworkManager. For more information, see the nmcli(1) manual page.
