Using Remmina, to remote from Ubuntu PC to another Ubuntu PC (home network), can I use RDP; or RDP is a Windows Protocol (Remote from Ubuntu to Windows) ?

I am getting "Cannot Connect to the 192.126.1.69 RDP Server" error.

Do I need to configure Remmina to connect from Ubuntu PC to Ubuntu PC via VNC instead? And if so; do I need to install what 'VNC' and on both PCs, or target PC only ?

Thanx

I did figure it out.

  • I can remote from Ubuntu PC to Ubuntu PC by installing Xrdp Server on Traget Ubuntu PC. I assumed Remmina will install the necessary servers. It is not the case; after installing Remmina, install RDP Server, and configure ufw Firewall on Target PC.

Instructions are from How to Install Xrdp Server (Remote Desktop) on Ubuntu 20.04 | Linuxize.

  1. Update first

  2. Xrdp is incuded in the default Ubuntu repositories; to install, run:

    $ sudo apt install xrdp

  3. When installation is complete, the Xrdp service will automatically start. You can verify by typing:

    $ sudo systemctl status xrdp

  4. By default Xrdp uses the /etc/ssl/private/ssl-cert-snakeoil.key file that is readable only by members of the ssl-cert group. Run the following command to add the xrdp user to the group :

    $ sudo adduser xrdp ssl-cert

  5. Restart the Xrdp service for changes to take effect:

    $ sudo systemctl restart xrdp

Firewall:

To allow access to the Xrdp server from a specific IP address or IP range, for example, 192.168.33.0/24, you would run the following command:

$ sudo ufw allow # from 192.168.33.0/24 to any port 3389

If you want to allow access from anywhere (which is highly discouraged for security reasons), run:

$ sudo ufw allow 3389

You can also connect via VNC, which is more "natural" for Linux than RDP which is a Windows protocol.

To connect via VNC, you have to install "vino" server on the target PC. I described the procedure here: what is the easy/minimal way to remotely(over the Internet) connect a Ubuntu 20.04 system from another Ubuntu 20.04 system?

    Thank you for mentioning so; coming from Windows, thinking like using Windows OS; I will try out VNC, since you say it's more natural for Linux.. a nice way of putting it.. Thank you
