YaST, the setup tool used for the installation, is also the configuration tool for SUSE LINUX. This chapter covers the configuration of your system with YaST. This includes most of the hardware, the graphical user interface, Internet access, security settings, user administration, installation of software, system updates, and system information. This chapter also provides instructions for using YaST in text mode.

The system configuration with YaST takes place by means of various YaST modules. Depending on the hardware platform and the installed software, there are different ways to access YaST in the installed system.

In KDE or GNOME, start the YaST Control Center from the SUSE menu (System+YaST). Additionally, the individual YaST configuration modules are integrated in the KDE Control Center. Before YaST starts, you are prompted to enter the root password, because YaST needs system administrator permissions to change the system files.

To start YaST from the command line, enter the commands su (for changing to the user root) and yast2. To start the text version of YaST enter yast instead of yast2. Also use the command yast to start the program from one of the virtual consoles.


To change the language of YaST, select System+Select Language in the YaST Control Center. Choose a language, exit the YaST Control Center, log out from the system, and log in again. The next time you start YaST, the new language setting will be active.

For hardware platforms that do not support a display device of their own and for remote administration on other hosts, run YaST remotely. First, open a console on the host on which to display YaST and enter the command ssh -X root@<system-to-configure> to log in to the system to configure root and redirect the X server output to your terminal. Following the successful SSH login, enter yast2 to start YaST in graphical mode.

To start YaST in text mode on another system, use ssh root@<system-to-configure> to open the connection. Then start YaST with yast.

2.1. The YaST Control Center

When you start YaST in the graphical mode, the YaST Control Center, as shown in Figure 2.1, “The YaST Control Center”, opens. The left frame contains the categories Software, Hardware, System, Network Devices, Network Services, Security and Users, System, and Miscellaneous. If you click the icons, the contents are listed on the right-hand side. Then select the desired element. For example, if you select Hardware and click Sound to the right, a configuration dialog opens for the sound card. The configuration of the individual items usually consists of several steps. Press Next to proceed to the following step.

The left frame of most modules displays a help text, explaining the required entries. To get help in modules without a help frame, press F1 or choose Help in the menu. After making the needed settings, complete the procedure by pressing Finish in the last configuration dialog. The configuration is then saved.
