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.

2.1. Starting YaST

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 sux (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 or for remote administration from 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 from another system, use ssh root@<system-to-configure> to open the connection. Then start YaST with yast.
