Using the "su" command will give you root permissions,
but may not set up the proper root environment for you
(for example, on some systems, it will not change the $PATH
to include the /sbin and /usr/sbin directories).
On suse: use the "sux" command. It gives you the proper
environment, plus it gives root access to the gui.
"sux" stands for su with X.
If you are using the konsole application in kde, then click and
hold on the new tab icon (bottom left of the window). You will
see a pop-up menu. Choose "Root Console".
If you are using xterm, or one of its siblings, use the command,
The dash tells su to use the root environment. And including
"/bin/" before the su command is just plain good practice. It will
prevent the super user from stumbling upon a program that some
(bad guy) used to replace the legitimate su command.
Hope this helps.
