Part 1: Confirming sshd service is Running on VMs.
# Switch to your '''c7host''' VM.
# Create a file in your current directory of your c7host machine with some text in it called: '''myfile.txt'''
# Issue Ensure you've successfully connected to the VPN required for Matrix (https://inside.senecacollege.ca/its/services/vpn/studentvpn.html). Then issue the following command (using your Matrix login id):<br><b><code><span style="color:#3366CC;font-size:1.2em;">scp &nbsp; myfile.txt &nbsp; yourmatrixid@matrix.senecac.on.ca:/home/yourmatrixid</span></code></b><br>(followed by your Matrix password)<br>What did this command do?
# Issue the following single command (arguments are separated by a space - use your Matrix login id):<br><b><code><span style="color:#3366CC;font-size:1.2em;">ssh &nbsp; yourmatrixid@matrix.senecac.on.ca &nbsp; ls /home/yourmatrixid/myfile.txt</span></code></b><br>(followed by your Matrix password)<br>What did this command do?<br>Issue the following Linux command:<br><b><code><span style="color:#3366CC;font-size:1.2em;">ssh &nbsp; yourmatrixid@matrix.senecac.on.ca &nbsp; cat /home/yourmatrixid/myfile.txt</span></code></b><br>How do these commands differ from using issuing the ssh command without the ls or cat command? How is this useful?<br><br>The client ssh application contains the utlities: '''ssh''', '''scp''' and '''sftp''' (learned in ULI101) to connect to remote Linux servers in order to issue commands or transfer files between Linux servers. You can install the SSH service on your Linux server, although this has already been performed upon installation. We will now confirm that the ssh service is running on all of your VMs.<br><br>
# OpenSSH should have been installed by default. Let's confirm this by issuing the command:<br /> <b><code><span style="color:#3366CC;font-size:1.2em;">rpm -qa | grep ssh</span></code></b>
<li>Make sure the '''sshd''' service is running on '''all 3 of your VM's'''</li>
</ol>
