Course Description

All Linux Administrators must know how to manipulate and manage processes, be able to configure networking, and know how the logging system works. This course provides an introduction to Processes, Services, and Daemons and how to manage them in Linux. You will also learn about networking and how to configure basic networking on a Linux system. Then you will learn about the system logs and how to access and use them. This course is one of a series in the Skillsoft learning path that covers the objectives for the Red Hat Enterprise Linux 7 RHCSA exam (EX200).
