In Unix/Linux, a '''shell''' is simply an '''interface''' to allow a user to communicate with the Linux computer system (server). Linux shells have evolved (improved) over a period of time. You will be using the '''Bash Shell''' which is considered to be ''user-friendly''. By understanding how to issue Linux commands, you can create a file that contains Linux commands (called a '''shell script''') later in this course to automate tasks to make you a more '''productive''' Linux user and system administrator.

Seneca College is "rolling-out" additional measures to improve '''network security'''. One of these measures is to implement '''multi-factored authentication'''. As of '''September 2020''', all Seneca College students are required to connect to the '''Seneca GlobalProtect Student VPN''' in order to be able to connect to their '''Matrix''' Linux account.<br><br>''<b>Multi-factor authentication</b> is an electronic authentication method in which a computer user is granted access to a website or application only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism: knowledge (something the user and only the user knows).'' Reference: https://en.wikipedia.org/wiki/Multi-factor_authentication<br><br>You should have received an email message (also available in course announcements) regarding how to setup your Smart Phone to connect and valid via the Seneca GlobalProtect Student VPN. '''NOTE:''' If you haven't done this yet, please perform the steps provided in the following link:<br>https://employees.senecacollege.ca/spaces/77/it-services/wiki/view/3722/student-vpn<br><br>
In the next investigation, you will learn how to '''connect''' to and '''login''' to your Matrix server account from a remote computer<br>such as your '''home desktop computer''', '''laptop''' or '''tablet''' computer.<br><br>
