For simplicity, the rest of this guide refers to these methods as Method 1, Method 2, and Method 3. Start VNC with the vncserver command. Upon completion, you can find the default configuration files and the password file hidden in the. In the above example, the display ID is 2. For example:. 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. Jack Wallen shows you how with the command-line Siege tool.

From the client-side, we have a tool called a VNC Viewer. Here also we have one disadvantage in TigerVNC Server is it used RFB protocol to transfer data over the network which is completely not secure but better than telnet. But we can implement an extra security layer for VNC Server. Before we start the configuration of TigerVNC Server we have to install required packages and dependencies. So create users using useradd command as shown below. Now I am going to create two users i. Note: Here is an example I have created Two users but you can create as much user you want as per your Scenario and Requirement.
Once users created we need to Switch to both users using su command and have to generate a password for VNC Server. Refer to the output below. So Follow the below steps to do the same. Configuration parts are highlighted in Red color. You can use different ports as per your requirement. After start the VNC Server service it creates script file xstartup and log file which is located at. VNC Viewer which is freely available. VNC server ports starts from tcp by default and session number is added to find related port number.
There is no problem if the client and server applications are different. In this situation we use Tightvnc client too. First open client. And put the host and session information like above ubu There is also alternative expression format by provided port number directly like ubu And click connect. There is also Options part which is used to configure connection parameters like window size, compression algorithm, compression ratio, cursor behavior etc.
By default VNC is not an encrypted protocol. This can create security problems. One of the steps to take in order to make more secure is tunneling via encrypted channels like ssh tunnels. Ssh encrypted and secure protocol. Ssh provides tunneling which can be used for all network streams and connections.
Following command will create a secure channel between client and server. Killing will just stop provided session and do not kill whole VNC server or other sessions do not provided. There is a practical command which will use session number like below. That is so elegant and logical and clearly explained.

Enabling VNC for the root user would create a serious security risk to your system that you'll generally want to avoid. Leaving the root user out of VNC and configuring a dedicated account with limited permissions instead - like the one in the above example - is definitely a better choice.
