To start the YaST administration tool, from the graphical interface of your server you can press Alt+F2 to open the Run Application dialog box. From there, issue the command yast to start the YaST management utility. If you are logged in as an ordinary user, next you have to provide the root user's password for complete access to all the possibilities. This is not a necessity, but it is recommended that you do it anyway, or else you won't be able to modify most of the settings. If you were already logged in as root, you don't need to supply an additional password. Next, you will see the main screen of the YaST management utility, as shown in Figure 3-1.
Note You may have heard of YaST2 instead of YaST. Both refer to the same management utility. If from a console window on the graphical desktop you use the yast command, the text-based version of YaST starts. This interface offers the same options as the graphical interface and is an excellent choice if you want to use YaST from a nongraphical environment. In this chapter, I'll use YaST to refer to both YaST and YaST2.
In the YaST management interface, on the left you can see all the categories of management utilities. In this book, I will refer to them as YaST menu options. These give you access to the management utilities, which appear on the right side when you select a menu option. The following menu options are available:
• Network Devices
• Network Services
• Novell AppArmor
• Security and Users
The following sections describe the most important tasks you will find in these menus.
