In SUSE Linux Enterprise, YaST handles both the installation and configuration of your system. This chapter describes the configuration of system components (hardware), network access, and security settings, and administration of users. Find a short introduction to the text-based YaST interface in Section 8.12, YaST in Text Mode. For a description of manual system configuration, see Section 20.3, System Configuration via /etc/sysconfig.
Configure the system with YaST using 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 main menu. 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, enter yast instead of yast2. Also use the command yast to start the program from one of the virtual consoles.
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 as 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.
To save time, the individual YaST modules can be started directly. To start a module, enter yast2 module_name. View a list of all module names available on your system with yast2 -l or yast2 --list. Start the network module, for example, with yast2 lan.
