===Connecting to the Seneca GlobalProtect Student VPN===[[Image:gp1.png|thumb|right|130px|'''Seneca GlobalProtect 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 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://students.senecacollege.ca/spaces/186/it-services/wiki/view/1025/student-vpn<br><br>

[[Image:cli-prompt.png|right|80px|]]After There are two basic methods to connecting to the Seneca GlobalProtect Student VPN, you can open a '''command terminal'''<br>in your '''Newer Windows 10''', '''Mac''' or '''Linux''' computer and issue the following command:<br><br><span style="color:blue;font-weight:bold;">ssh senecauserid@matrix.senecacollege.ca</span><br><br>[[Image:ssh-application-icon.png|right|80px|]]You can also click on the following link to '''download''' and '''install''' a graphical SSH application for your Windows machine:<br>httpsMatrix account://www.sfsu.edu/ftp/win/ssh/SSHSecureShellClient-3.2.9.exe<br><br>

[[Image:apps-anywhere-main-window.png|thumb|right|250px|* From your '''MyAppshome computer''' (<br>:* From a '''AppsAnywhereworkstation in a Seneca College''') Main Window ]]If you were able to access one of Seneca computer labs, you could access an application to connect to your Matrix account lab via the '''MyApps''' application.

Reference===METHOD 1: https://inside.senecacollege.ca/its/software/myapps/CONNECTING TO YOUR MATRIX ACCOUNT FROM YOUR HOME COMPUTER===

'''NOTE:''' Although you can install and run the AppsAnywhere application on an Apple Mac computer, you will NOT have access to many of the Windows applications (including applications to connect to your Matrix account). In this case, you can open a '''terminal''' and issue the '''ssh''' command to connect to your Matrix account.  --> ===CONNECTING TO YOUR MATRIX ACCOUNT FROM A COMMAND LINE TERMINAL=== [[Image:gp1.png|thumb|right|130px|The '''GlobalProtect Seneca Student VPN''' service must be connected.]]

'''Perform the Following Steps:'''# Before proceedingIf you want to connect to your Matrix account from home, make you MUST first connect to the Seneca Student VPN.<br>Make certain that your '''Seneca GlobalProtect Student VPN is connected'''.<br><br>'''NOTE:''' If you haven't set this up, refer to the following link for instructions;<br>https://students.senecacollege.ca/spaces/186/it-services/wiki/view/1025/student-vpn<br><br>'''NOTE:''' You only have to connect to your Seneca GlobalProtect student VPN once during the day,<br>or while you are logged into your computer.<br><br>

Another advantage of using this method is to introduce you to a '''graphical program''' to allow you connect to your Matrix account as opposed to using the '''ssh''' command (shown in the previous section).<br> [[Image:apps-anywhere-main-window.png|thumb|right|250px|'''MyApps''' ('''AppsAnywhere''') Main Window ]]This method would also be useful if you do '''not''' have a home (notebook) computer and have access to a Seneca computer lab workstation.<br><br>
