<ol><li value="4">When connecting securely for the '''first time''', a '''dialog box''' will appear to share a "'''public key'''" with your Matrix account in order to make your interaction between your workstation and the remote Linux server secure within the network (i.e. encrypted to prevent unauthorized access by other users)<br><br>''<b>FYI:</b> To make communications over a network secure, a computer generates '''two keys''': a '''private key''' that is kept on the computer, and a '''public key''', which can be shared with other computers. Transmissions from your computer uses the private key to encrypt ('''scramble''') transmission to the remote computer, which in turn, uses the public key to decrypt (unscramble) the transmission. Likewise, the remote computer uses the public key to encrypt (scramble) transmissions and your computer uses the private key to decrypt ('''unscramble''') those transmissions.''<br><br></li><li>Type '''yes''' and press '''ENTER''' to share your public key.<br><br>Next, a '''dialog box ''' will appear prompting you for your Matrix account '''password''' in order to gain entry to your Matrix account. Your Matrix password is identical to your Seneca password. As you type the password, the text will be blocked-out or hidden to prevent others from viewing the screen to obtain your password<br><br></li><li>Enter your Seneca password and press '''ENTER'''<br><br></li>'''NOTE:''' If you encounter an '''error message''', this can occur for several reasons:<ol><li>You mis-spelled the '''name of the server'''</li><li>You mis-spelled your Matrix '''username''' (same username that you connect to ''my.senecacollege.ca'')</li><li>You have '''CAPS LOCK''' on by mistake (your username should be '''lowercase''' only).</li><li>You mis-spelled your '''password''' (same password that you connect to ''my.senecacollege.ca'')<br><br>If you continue to experience the same problems, click on the following link for IT service desk contact info: <br>[https://employees.senecacollege.ca/spaces/122/support/wiki/view/3524/contact-its '''IT service desk'''].<br><br></li></ol>
<li>If you entered your password correctly, the '''Matrix Linux shell''' should appear where you can enter Linux commands.<br><br>The '''Matrix''' server has been configured to allow users to '''only interact with the Linux OS by issuing commands'''.<br>The main reason for this is to '''force students to learn how to issue Linux commands'''.<br><br></li><li>To exit your Matrix session, type the command <span style="color:blue;font-weight:bold">exit</span> followed by '''ENTER'''<br><br>'''NOTE:''' You should notice that you are returned to the original command prompt where you issued the ''ssh'' command.<br><br></li><li>Type the same command and the '''command terminal prompt''': <span style="color:blue;font-weight:bold">exit</span> followed by '''ENTER'''<br><br>
'''NOTE:''' You should notice that the you are disconnected and that the original terminal window has '''automatically closed'''.<br><br></li><li>Try accessing your Matrix account, and then exiting your Matrix account several times to become familiar with this process.<br><br>You will now learn an alternative method to access your Matrix account (if you have an MS Windows machine)<br>by downloading and running a graphical SSH application.</li></ol><br>
