Chapter 10 . Running SUSE Linux 319 YaST offers you some intuitive tools for configuring your system and comes preconfigured, so you start with a nice set of defaults. YaST also does a good job detecting your hardware, finding partitions, and the like, so a new user can often just accept the settings YaST chooses. Here are some examples of what YaST does for you: . Detects hardware. You don t have to check through /etc configuration files or run lsmod to see how your hardware has been configured in SUSE. From the Hardware section, you can select icons representing your CD drives, graphics cards, printers, joysticks, scanners, sound cards, and mice. Click the Hardware information icon to see your full list of detected hardware. . Manages system configuration. Like Red Hat Linux, SUSE stores much of the information it uses to configure services at boot time in files in the /etc/ sysconfig directory. The information in those files is in the form VARIABLE= VALUE . Under the YaST System icon, you can select the sysconfig Editor, which lets you select each file, and then view and possibly change each variable so that you don t have to guess what variables are available for each configuration. For more advanced system administrators, this is a great way to fine-tune the startup services for your system. SUSE also includes a System Configuration Profile Management (SCPM) applet, which lets you store and manage a collection of system settings so it can be used again later. . Configures network devices. YaST detects your dial-up modem, Ethernet card, DSL modem, or ISDN hardware, and gives you the opportunity to configure each piece of hardware. SUSE also does a much better job than most distributions at getting Winmodems working in Linux, which is particularly useful for using dial-up features on laptops that have cheap, built-in modems. . Defines network services. With a connection to your LAN or WAN, YaST provides some helpful graphical tools for configuring some services that can be unintuitive to do from the command line. . Changes security settings. Security settings in Linux are often among the most unintuitive features to configure, while at the same time being among the most important. Although features such as iptables work great for most Linux gurus for setting up a firewall, people who are accustomed to graphical interfaces may find them challenging. From the YaST Security and Users selection, the Firewall icon enables you to step through your network interfaces and add access to those services you want by name (such as Web Server, Mail Server, and Other Services) or by port number. It even enables you to do initial setup of more complex firewall features, such as packet forwarding, IP Masquerading, and logging.
