If you do not recall the active session display ID, use the vncserver -list command to find it. To customize settings such as screen size, security type, etc. To configure VNC for this method, you must have root privileges. You will set up a systemd service file for all intended VNC users with their own preassigned unique display ID.

Create a systemd service script file vncserver :[X]. Be sure the correct username is entered in the User field. The example below shows user vnc-user-b who is assigned the display ID 5. Have each user log into their account and set a VNC password with the vncpasswd command before proceeding to the next step. Start the VNC service script and set it to start automatically on boot for each user. Replace the [X] with the display ID.

The example below shows 2 VNC sessions that were successfully started for users vnc-user-b with display ID 5 and vnc-user-c with display ID 6. You must have root privileges to perform this configuration. Create a systemd socket file xvnc. Create a systemd service file xvnc. Create a GDM custom. An SSH client is only needed if you chose to use Method 1 or you plan to encrypt your VNC traffic, which is discussed later in this guide.

On Windows, you can install Putty. Under the Category section, select Session. See Figure 1. Set the Connection type option to SSH. Take note of the generated display ID because you will input it into the VNC viewer app to establish the connection.

The above example shows the display ID is 3. VNC automatically picks a unique display ID unless you specify one. To specify a display ID, enter a unique number that is not already in use after the colon. You can now end the SSH connection by logging out. This does not terminate your active VNC session. For Method 1 and Method 2, you must connect to a specific active session or display ID using one of two options:.

For example, if the display ID is 3, it can be specified as or just as 3. Use For simplicity, the instructions below use the fully-qualified VNC port number. The following screenshot shows connecting to Clear Linux OS host Follow these steps:. Right-click a connection node and select Properties…. See Figure 3. Select the ColorLevel setting and change it to your preferred setting.

If you want to truly terminate an active VNC session, follow these steps:. Terminate it with the vncserver -kill command followed by a colon and the display ID. For Method 3, only the system administrator can stop and disable the VNC service by using these commands:. By default, VNC traffic is not encrypted. This is accomplished by following these steps:.

Configure the VNC server to only accept connection from localhost by adding the -localhost option. Your client system will forward traffic from the localhost the client destined for a specified fully-qualified VNC port number on the client to your Clear Linux OS host with the same port number. It should look like this:. Edit the systemd service script vncserver :[X].

Right after that, you should create a dedicated VNC user to connect with with a dedicated password. Once you created the vncuser and its login password, you also need set a VNC-unique password for that user. This can be done with the following command:.

That "1" which we put in the new filename is the display number that will be used for that specific service instance. Right after the copy, you need to edit the new file using vi , nano or another text editor and replace the [USER] placeholder with the name of the user created a short while ago vncuser in our scenario. Here's how the file should look after the update minus the long commented part at the beginning :.

As soon as you do that, you can reload the VNC daemon and start the vncserver 1 with the commands below:. Before proceeding, it could be wise to check if the service is running by issuing the systemctl status command Another check you can do before trying to connect to our server is to take a look to the active network sockets using the ss command: if everything works properly, you should see a VNC server running and listening on port TCP Since our VNC service is listening to port TCP , you need to be sure that such port is open and accessible by external clients: therefore, if you have a firewall installed, you should create an appropriate rule to allow VNC clients to connect.

How many ports to open will depend by how many instances of VNC servers you'll going to need: in our scenario, you only made 1, therefore you only need to open the first allocated VNC port: TCP , just like we said. Here's the command to open that port on firewalld :. Needless to say, you can also restrict that port for specific groups, IP addresses, network cards or other simple or complex firewall rules: that's entirely to you, depending on your network environment's configuration and how much you want to be safe.

If you already have GNOME, KDE or other desktop environments installed on our system you can skip this step, otherwise you'll need to add one: the TigerVNC server will start a parallel instance of a given desktop environment for each login session, meaning that we need to have one - otherwise it won't work. Don't misunderstand us here, GNOME works fine as well, but it's quite space-and-resource-intensive: if you want to save resources on your server machine, Xfce would arguably be a better choice.

If you've chosen to use Xfce , you'll also need to change the file to execute when the VNC session starts. Just remember to specify the port TCP if you've followed our guide. In case your client is unable to establish a working VNC connection, you need to checkup the following:. That's about it, at least for the time being: we hope that this guide could help other System Administrators who want to connect to their servers with the VNC protocol!
