Hi
When will explain all of these services in this page
Regards
You don’t need to know most of these modules; YaST is a framework within which many modules can be accessed but not all modules are relevant to all users.
If it isn’t obvious to you from the name that you need to use it on your computer, you can ignore it. When you use it, you should find enough information on how to use it.
If you want more go to Novell Doc: OpenSUSE 11.1 - Table of Contents
I want to know that because operation of some services.
Thank you for the answer.
