Course Description

A Linux system administrator needs to know how to configure the time, e-mail, printing, and logging features of a Linux system. In this course, you will learn about four of the essential services almost all Linux servers and clients will have configured: NTP time synchronization for accurate time, Mail Transfer Agents for e-mail, CUPS for printing, and the system logger to manage log messages. This course also covers configuring GUI interfaces using X server. This course is one of a series in the Skillsoft learning path that covers the objectives for the CompTIA Linux+ exams LX0-104.
