The first thing to do is to install the TigerVNC Server program by opening a terminal session and entering the following command with root privileges:. Immediately after that, you need to create a separate VNC user from which the connection will be made with a dedicated password. To do this, enter the following:. Important: never do this as a root user - this will pose a serious threat to the security of your system.

The best solution would be to leave the root user without access to VNC and set up a dedicated account with limited rights. After you create vncuser and set a password for logging in, you also need to set a unique VNC password for this user. The command to do this is:. The next thing to do is create a VNC configuration file for vncuser. The number 1 that we added to the new file name is the display number that will be used for this particular instance of the service.

The first will be , then and so on. Immediately after copying you need to edit the new file using Vi, Nano or another text editor, and replace [USER] with the name of the user created recently in our case, vncuser. This is how the file should look after the update except for the long commented part at the beginning :. Once you do this, you can reload the VNC daemon and run vncserver 1 with the following commands:. Before proceeding, verify that the service is running by entering the systemctl status command:.

Another test that you can perform before trying to connect to the server is to look at the active network sockets using the ss command: if everything works correctly, you should see that the VNC server is working and uses TCP port Execute the command:. Since our VNC service is listening on TCP port , you must be sure that such a port is open and accessible to external clients. Therefore, if you have a firewall installed, you must create an appropriate rule that allows VNC clients to connect.

How many ports to open will depend on how many VNC server instances you need. The command to open this port on Firewalld:. It will not be superfluous to mention that you can also restrict this port to certain groups, IP addresses, network cards, or other simple or complex firewall rules. Otherwise, you need to install one of them: the TigerVNC server will start a parallel instance of this desktop environment for each login session, which means that we must have at least one GUI. If you need a lightweight alternative, we can offer Xfce, a free, open-source environment for Unix-like platforms that works great with TigerVNC.

If you need a lightweight alternative, we can offer Xfce, a free, open-source environment for Unix-like platforms that works great with TigerVNC.

GNOME also works great, but it quite resources intensive: if you want to save resources on your server machine, Xfce might be the best choice. To install it, enter the following:. Execute the command below to open and edit the file using the nano editor. When you launch a VNC instance on your server, you will see an argument like What this means is that VNC is running on port If running on port , you would see :2 , port would be represented as :3 , and so on.

Now, if you have multiple users on your system, you can map each one of them to a particular port. To do so, we will edit the vncserver. If you have more users, map them to ports :2 , :3 , :4 , and so on. We have done all the necessary configurations up to this point, and we can now start the VNC server. The command below launches a VNC instance with display port :1 , which refers to port as discussed above.

Therefore, it can easily suffer from attacks like sniffing. Note : The local port, , can be any number but not more than and not running another service. We just used for convenience. In my case it will be Source port: and Destination: localhost When done just click on the Add button and then Open to start the session. You will have to just log in via the Putty terminal and the SSH tunnel will be created and now you should be able to connect to the VNC server using your client to Once you have established an SSH tunnel, we can now connect securely to our server.

In this example, we will use Vinagre. Since I am running Ubuntu, I can easily install Vinagre with the command below. You can also easily install and use Remmina , instead of Vinagre. If you are using an SSH tunnel, connect to the VNC server using the localhost address and bind it to port , as shown below.

If you used a different display port other than :1 , then use the required port number. Once done, click Connect. You will see a prompt to enter the password you set when you once execute the vncpasswd command. After a successful connection, you should see the CentOS graphical desktop, as shown in the image below. You can download it for multiple operating systems as well, such as Mac , Linux , iOS , Android , and more.
