Description
This course is a practical extension to Unix System Administration, covering the more complex administration requirements of networked and large Unix systems.

Audience
Administrators of large Unix systems or networks of Unix systems. The course is also valuable for technical support staff for these systems.

Prerequisites
Experience in Unix system administration.

Hardware and Software
A Unix network running Unix V.4, with NFS, TCP/IP, and NIS all running. Terminals, printers, and associated cabling should be provided. Any Unix system V-based network with NFS, NIS, and TCP/IP may be substituted for the prior requirement.

Format

• Presentation
  
• Hands-on
  

Objectives
After completing this course, participants should be able to:

• Install and configure a System V.4 environment
• Install new devices and software
• Set up networks and networked file systems
• Use the X Window system
