3.3 KInternet—Tool for User Controlled Devices

If you do not use NetworkManager and do use KDE, manage your Internet connections with KInternet, package kinternet. The program checks whether an Internet connection can be established. If this is possible, the application icon, a plug, automatically appears in the right section of the KDE panel. Depending on the state of the network connection, the panel icon changes appearance:

Currently there is no connection to the Internet.

The connection is being established or terminated.

The connection has been established.

Data is being transmitted to or from the Internet.

An error has occurred. If a connection has already been configured with YaST, use View Log to identify the reason for the error. Access the menu by right-clicking the KInternet icon.

The connection is not yet active, but will be established as soon as a request is made.

HINT: Controlling the Connection from a Command Line

If you work in the command line or in a desktop where it is not possible to use KInternet, you can use cinternet. cinternet is a simple command line application. For detailed information, refer to the cinternet(8) man page.

KInternet does not provide any VPN configuration dialog. Configure a VPN connection manually or using a dedicated client program.

3.3.1 Access YaST from KInternet

Right-click the KInternet panel icon to access its configuration menu. Start the YaST configuration dialog with Settings Configure with YaST . After entering the root password, YaST starts. Depending on the access type, start the modem, ISDN, network, or DSL configuration of YaST.

If you are using an ISDN connection and selected Channel Bundling in YaST, add a second ISDN channel to an existing connection with Add link. This doubles the transfer rate (although at a higher price). Activate channel bundling if you need to download large files. Activated channel bundling is displayed with a red plus symbol at the top left corner of the KInternet icon.

3.3.2 Multiple Network Interfaces

If your computer has more than one network device and you have configured all of them with YaST, you can use the KInternet option Interface to switch between these interfaces. If you have multiple providers as well, choose them using Provider in KInternet. Providers are also set in YaST.

To enable other network interfaces in the KInternet, you must have selected User Controlled device activation in the appropriate YaST network dialog.

3.3.3 Automatic Connection

To establish Internet connections automatically, use dial on demand (DoD). If this mode is selected, KInternet automatically connects to your Internet service provider (ISP) as soon as a request is submitted. After a certain time-out, the connection is terminated. A DoD connection is shown with a blue D at the bottom right corner of the KInternet icon.

Note that DoD only makes sense if you have a flat rate Internet account. If that is not the case, connecting and disconnecting all the time can become very costly.

3.3.4 Wireless Cards

To access the WLAN functionality of KInternet, right-click the icon to open the menu. Select Wireless Connection and a window showing two tabs opens. First, scan for suitable wireless networks to which to connect. Select the Scan for Wireless Networks tab and start the scan with Start Scan. For KInternet to continuously scan the network environment, also select Auto Refresh. Activate acoustic feedback for each connection found with Acoustic Scan. Any connection found is displayed in the list window. Select one and click Connect to connect to the selected network. If additional configuration efforts are needed to connect to the selected network, click Start YaST to open the YaST network module for wireless network devices.

NOTE: Hidden Networks

KInternet does not provide support of networks that do not broadcast their service set identifier (ESSID).

The Current Connection tab allows you to monitor the state of your current wireless connection. The left-hand view of this tab offers a summary of all connection parameters for network address and ESSID, signal quality, signal and noise level, channel frequency and speed, and encryption parameters, such as type of encryption and key length. Select any of these parameters in the tree structure and see the details displayed in the right part of the window.
