YaST also offers interfaces for configuring and starting network devices, as well as a variety of services
to run on those devices. In addition, you can use YaST to configure your computer as a client
for file sharing (Samba and NFS), e-mail (sendmail), and a variety of network services.
SUSE Linux Enterprise Server comes with a wider range of configuration tools that are specifically
geared toward server setup, including tools for configuring a mail server, VPN tunnels, and full
Samba 3. While other distributions may include proprietary tools, YaST is in a class of its own.
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.
Think of the root user in Linux as analogous to the Administrator user in Windows.
When you first install most Linux systems, you add a password for the root user.
