Who Should Attend:

System administrators, software engineers, system analysts, managers, students, and other IT professionals who wish to learn about using the Networking, Basic Security and Linux based network services.

Prerequisites:

Linux Operating system knowledge such as command line experience, basic utility knowledge and experience with scripting is expected.

Objectives:

This module provides the participant who is already familiar with basic Linux administration with an understanding of how to set up, troubleshoot, and maintain Linux networks, focusing on Linux. Topics covered include setting up Ethernet and Routing, NFS, how to administer the Network File System (NFS) the Network Information Service, and DNS.

Hands-on sessions will be provided on Linux. If possible, participants are requested to state in their registrations their preferred Unix/Linux platform for their hands-on sessions. Every effort will be made to satisfy the participants' selections whenever possible and within resource constraints.

This module is more practical in nature compared to N203: Networking with TCP/IP.
