In SUSE LINUX Enterprise Server, YaST handles both the installation and the configuration of your system. This chapter describes the configuration of system components (hardware), network access, and security settings and administration of users. A short introduction to the text-based YaST can be found at the end of the chapter.

2.1. Starting YaST

Use various dedicated YaST modules customized for specific purposes to configure a system. Depending on the underlying hardware platform, there are different ways to access YaST in the installed system.

2.1.1. Running YaST on a Graphical Desktop

If you are running KDE or GNOME, start the YaST Control Center from the SUSE menu (System->YaST). KDE additionally integrates the individual YaST configuration modules in the KDE Control Center. A requester dialog asks for the root password, because YaST requires system administrator rights to change system files.

To start YaST from a terminal application, first change to the user root with sux. Then start the graphical version of YaST with yast2 or the text version with yast. Also use yast as root to start the program from one of the virtual consoles.

2.1.2. Running from a Remote Terminal

This method is suited for hardware platforms that do not support a display device of their own, such as IBM S/390 and zSeries. It can also be employed for remote maintenance purposes.

  1. Open a console or terminal.

  2. Enter the following command to log in as root on the remote system and export the output of the X server to your terminal.

    ssh -X root@<host to configure>
  3. Once the connection is established and you have logged in with the correct password, enter yast2 to open the graphical version of YaST on your local system. To use the text version, skip the -X when opening the connection and use yast to open the text-based YaST.
