Linux User Notification and Device Management

Target Audience

Course Number

Because Linux and UNIX were designed from inception as multi-user operating systems, there is often the need for a system administrator to provide information about system status and future availability to all users. Rather than send an e-mail to all users, Linux provides facilities for an administrator to post public notices and messages for all users to see. This course covers the methods available to a system administrator for user notification. This course also demonstrates the system used by Linux to detect and initialize hardware devices on the system - both those found during boot up, as well as those plugged in later such as USB flash drives. This course is for people taking Advanced Level Linux Professional (LPIC-2) Exam 201.

Target Audience
Administrators who are rolling out and supporting Linux in the enterprise; individuals seeking internationally recognized, distribution-neutral Linux certification

Candidates must have an active LPIC-1 certification to receive LPIC-2 certification, but the LPIC-1 and LPIC-2 exams may be taken in any order.
