  1. Challenge

    Allow Susan SSH access from host susan-ws.office21.net

    1. Edit the /etc/ssh/sshd_config file with the following line:
    sudo vi /etc/ssh/sshd_config
    • enter password for cloud_user
    AllowUsers [email protected]

  2. Challenge

    Permit root SSH login from the subnet 10.0.1.0/24

    1. The first step is to permit root logins by removing the comment in front of the line #PermitRootLogin yes in the /etc/ssh/sshd_conf file.
    2. Secondly, we need to add [email protected]/24 to the AllowUsers line in the /etc/ssh/sshd_config file.
    3. Now we need to restart the sshd service so the changes we made will take affect:
    systemctl restart sshd
