OpenSuSE 11.1 Quick Start Guide

10.5 Using GNOME NetworkManager Applet

In GNOME, NetworkManager can be controlled with the GNOME NetworkManager applet. If the network is set up for NetworkManager control, the applet usually starts automatically with the desktop environment and is shown as an icon in the system tray.

If your system tray does not show GNOME NetworkManager applet, the applet is probably not started. Press Alt+F2 and enter nm-applet to start it manually.

10.5.1 Connecting to Wired Networks

If your computer is connected to an existing network with a network cable, use the NetworkManager applet to choose the network connection.

  1. Left-click the applet icon to show a menu with available networks. The currently used connection is selected in the menu.

  2. To switch to another network, choose it from the list.

  3. To switch off all network connections, both wired and wireless, right-click the applet icon and uncheck Enable Networking.

10.5.2 Connecting to Wireless Networks

Available visible wireless networks are listed in the GNOME NetworkManager applet menu under Wireless Networks. The signal strength of each network is also shown in the menu. Encrypted wireless networks are marked with a shield icon.

Connecting to a Wireless Network

  1. To connect to a wireless network, left-click the applet icon and choose en entry from the list of available wireless networks.

  2. If the network is encrypted, a dialog opens. Choose the type of Wireless Security the network uses and enter the appropriate Password.

  3. To connect to a network that does not broadcast its service set identifier (ESSID) and therefore cannot be detected automatically, left-click the NetworkManager icon and choose Connect to Other Wireless Network.

  4. In the dialog that opens, enter the ESSID and set encryption parameters if necessary.

  5. To disable wireless networking, right-click the applet icon and uncheck Enable Wireless. This can be very useful if you are on a plane or in any other environment where wireless networking is not allowed.

10.5.3 Configuring Your Wireless Card as an Access Point

If your wireless card supports access point mode, you can use NetworkManager for configuration.

  1. Click Create New Wireless Network.

  2. Add the network name and set the encryption in the Wireless Security dialog.

    IMPORTANT: Unprotected Wireless Networks Are a Security Risk

    If you set Wireless Security to None, everybody can connect to your network, reuse your connectivity and intercept your network connection. To restrict access to your access point and to secure your connection, use encryption. You can choose between various WEP and WPA–based encryptions. If you are not sure which technology is best for you, read Authentication, (↑ Reference ).

10.5.4 GNOME Keyring Manager

If you do not want to enter your credentials anew each time you want to connect to an encrypted network, you can use GNOME Keyring Manager to store your credentials encrypted on the disk, secured by a master password. Whenever any GNOME application that uses GNOME Keyring needs to access passwords or credentials stored there, a check is made if the keyring is locked or not. If it is locked, you will be prompted for the master password to unlock the keyring. For more information about GNOME Keyring Manager, refer to Section 2.4.3, Managing Keyrings, (↑ GNOME User Guide ).
