===Connecting to the Seneca Student VPN===
[[Image:gp1.png|thumb|right|130px|'''Seneca Student VPN''' ]]
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 All Seneca College students are required to connect to the '''Seneca 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 Student VPN. '''NOTE:''' If you haven't done this yet, please perform the steps provided in the following link:<br>https://students.senecacollege.ca/spaces/186/it-services/wiki/view/1025/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>
=INVESTIGATION 1: ACCESSING YOUR MATRIX LINUX ACCOUNT=
<span style="color:red;">'''ATTENTION''': Effective '''May 9, 2022''' - this This online tutorial will be required to be completed by<br>'''Friday in week 2 by midnight''' to obtain a grade of '''2%''' towards this course</span><br><br>
In this section, you will learn how to access your Matrix Linux account by two different methods:
# Press the letter <span style="font-family:courier;color:blue;font-weight:bold">q</span> to exit the man command.<br><br>
# Issue the following Linux command to get help with the ls command: <span style="font-family:courier;color:blue;font-weight:bold">man ls</span><br><br>
# Navigate through the man utility for the '''ls''' Linux command and note the '''option letters''' that correspond to the following descriptions:<br><ul><li>"'''use a long lising listing format'''"</li><li>"'''do not ignore entries starting with .'''" (i.e. hidden files)</li><li>"'''sort by file size'''"</li><li>"'''append indicator (one of */=>&|) to entries'''" (i.e. type of file)</li></ul><br>
# Exit the man utility for the ''ls'' command.<br><br>
# Issue the '''ls''' command for <u>each</u> of those option letters you noted in '''step 5''' to see how this command differs for each option.<br><br>'''NOTE:''' The '''man''' utility can be used with the '''-k''' option to help list Linux commands that match a text pattern<br>that is contained within the help screen for a Linux command.<br><br>
# Create a '''table''' listing each Linux command, useful options that were mentioned in this tutorial for the following Linux commands:<br>'''pwd''' , '''cd''' , '''ls''' , '''cal''' , '''date''' , '''who''' , '''w''' , '''whoami''' , '''who am I''' , '''clear'''
