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 configure
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.
To make your way around the graphical YaST interface, you need only to click the mouse and use
the Tab key to move between fields. For the text-based YaST interface, you can use the Tab and
arrow keys to move among the selections and the Enter key to select the currently highlighted item.
RPM Package Management
Like Red Hat Enterprise Linux and Fedora, SUSE packages its software using the RPM package
management file format and related tools.
