Subject Title
Introduction to Open System Servers

Subject Description
This project-based subject will teach students how to install and configure a Linux server. Further, students will learn how to connect to and communicate over a network in a controlled environment. They will learn how to manage their files on their system and how to set-up file and directory permissions. Students will manage basic system security and firewall settings. In order to configure their system, students will gain knowledge of a few basic Unix/Linux commands and be exposed to 'Shell' basics. Finally students will work with both text and graphical user interfaces.

Credit Status
1 credit in the CNS/CTY Program.
