YaST, the setup tool used for 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. Both graphical and text modes of YaST are available and provide the similar functionality.
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
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.
To change the language of YaST, select + in the YaST Control Center. Choose a language, exit the YaST Control Center, log out of the system, then log in again. The next time you start YaST, the new language setting is used. This also changes the language for the entire system.
If you need work in a different language but do not want to
change the system language setting, you can temporarily change the
LANG variable. To do so, export
LANG with your preferred language. For example,
for English, enter the command:
export LANG="en_US"; yast2
This command changes the
LANG setting only in
your current session. The language setting of other users and your
other sessions, like terminal windows, remains unchanged.
If you run YaST remotely over SSH, YaST uses the language settings of your local system.
