Linux Level 2 - Linux System Administration Training Class Summary

This five-day course provides the student with the knowledge to perform system administrator tasks relating to the administration of filesystems, including set uid bit for permissions, partition management, mounting and unmounting, disk diagnostics, RAID, LVM and NFS disk types, and disk quotas. The course finishes with administration of hardware devices, basic networking, including TCP/IP, and system troubleshooting.

Audience: Entry level system administrators who want to move into more practical, in-depth Linux administration.

Prerequisites: Linux Level I or equivalent experience.

Class Length: 5 days
