Chapter 4 . Learning Basic Administration 131 Figure 4-3: Use the YaST Control Center to administer SUSE systems. Using the Root Login Every Linux system starts out with at least one administrative user account (the root user) and possibly one or more regular user accounts (given a name that you choose, or a name assigned by Linux). In most cases, you log in as a regular user and become the root user to do an administrative task. The root user has complete control of the operation of your Linux system. That user can open any file or run any program. The root user also installs software packages and adds accounts for other people who use the system. When you first install most Linux systems, you add a password for the root user. You must remember and protect this password you will need it to log in as root or to obtain root permission while you are logged in as some other user. Other Linux systems (such as KNOPPIX) start you with a blank root password, so you may want to add one when you first start up by typing the following from a Terminal window or other shell: # passwd root Changing password for user root. New UNIX password: ******** Retype new UNIX password: ********
