Demo Log into local amp remote graphical and text mode consoles

Welcome to this demonstration on three common Linux login methods. We’ll cover:

1. Local Graphical Login on CentOS

1. Power on your CentOS VM with GNOME installed.
2. At the login screen:
   • Click your Username.
   • Type your Password.
   • Press Sign In.
3. GNOME will load by default.
4. To end your session, click your user menu in the top-right corner and select Log Out.

2. Remote Graphical Login via RDP

On your host machine, launch the Remote Desktop client (e.g., Remote Desktop Connection on Windows or remmina on Linux).

1. Enter your VM’s IP address and click Connect:

sudo firewall-cmd --add-port=3389/tcp --permanent
sudo firewall-cmd --reload

2. When prompted, enter your Username (student) and Password:

3. After logging in, open Activities and launch GNOME Terminal:

3. Remote Text-Mode Login with SSH

From the GNOME Terminal in your remote session (student@LFCS-CentOS2), connect to the target VM (192.168.0.17) as user aaron:

ssh [email protected]

Once authenticated, you may see output like:

Activate the web console with: systemctl enable --now cockpit.socket
Last login: Tue Oct 19 04:22:38 2021

Your prompt should now reflect the remote host (e.g., aaron@LFCS-CentOS). When you’re done:

exit

This command closes the SSH session and returns you to student@LFCS-CentOS2. To end the graphical RDP session, simply log out or close the RDP window.

That’s all for this lesson. See you in the next one!
