I installed VNC on Ubuntu Starting the server in "once" mode means that people with user accounts on your computer would have to log in to your desktop between the time you start your VNC server and the time you connect from your VNC client. Setting a password means that, if anyone did try to connect in that brief interval, they probably wouldn't be able to get in before you noticed and stopped the server.

There's no way to set vino to only listen for the next connection. To set a password, tick Require the user to enter this password: , and enter a hard-to-guess password. To put vino in view-only mode, untick Allow other users to control your desktop. To only allow local connections, open a terminal and run the command: gsettings set org.

It can be started while your computer is still showing a login screen. It is helpful to ensure you have uninstalled any other VNC programs first so that they don't interfere with x11vnc. To set x11vnc to only listen for the next connection, include the -once option. To set x11vnc to continually listen for connections, include the -forever option.

To set krfb to request access each time, tick Confirm uninvited connections before accepting To set a password, type a hard-to-guess password into the Password input box. To put krfb in view-only mode, untick Allow uninvited connections to control the desktop. There's no built-in way to only allow local connections, although see below for a solution. Once mode Krfb doesn't have a built-in way to accept the next connection then stop listening for connection attempts.

However, the following Python script will listen for a single connection then exit krfb:! Make sure that the initial ' ' character is the very first character in the file, save the file as krfb. Although this simple program won't open a window of any kind, it will quietly wait for the next VNC client to connect to your computer, then pass the connection through to krfb.

This script will only listen for local connections. To allow connections from anywhere, change Invitations Krfb lets you create "invitations", or individual passwords that are deactivated after an hour or after one use. These are a handy way of giving people one-time access to a computer, but only provide limited security. For example, if you send someone an invitation by e-mail or instant messaging, an attacker could read your invitation message as it went over the Internet and use it to log in.

Invitations can be useful when you want to let other people view your desktop, but you still need to follow the normal precautions when letting other people view your desktop. This makes it much less useful for some things like remote help , but much more useful for others like creating a public area for collaboration.

If you intend to connect via VNC to an Ubuntu On booting up, you will get a command-line interface to execute your commands. As of writing this post, there are several Linux desktop environments available for you to install. For this particular post, we will install the XFCE desktop environment.

It is fast, stable, and easy to use. XFCE is very popular and lightweight. You can also install multiple desktop environments at the same time, and just switch between them. However , you may end up with bugs or conflicts, depending on the desktop environments you have simultaneously installed.

After establishing an SSH connection to your server, execute the following command to update your package index:. You will see a prompt to select a display manager for your newly installed XFCE Desktop Environment during the installation. There are several VNC servers available for Linux today. For this particular tutorial, we will install the TigerVNC server. Execute the command below to initialize the VNC server instance and set up a password. Assuming you are acting as a non-root sudo user , do NOT execute this command with sudo :.

After setting up the password, you will get a prompt to set a View-Only password. I will just type N and hit Enter. We can see this process lists the connection information for our VNC server from the message above. Additionally, it started the VNC server at port , which is the display port. This port is referred to as If you create additional VNC server instances, they will be presented as port as :2 , port as :3 , and so on.

Up to this point, our VNC server is up and running. Now we need to configure the commands that will be executed by the server every time we start a VNCV instance. Execute the command below:. If another instance were running on another port, say or , we would execute the commands vcnserver -kill :2 and vncserver -kill :3 , respectively.

To configure VNC, we will need to create a file called xstartup file in the. Execute the commands below:. By default, TigerVNC accepts connection only from In my case, I will use From the image above, you can now see our VNC server is well configured, and we can access it from our local machine.

To establish a secure connection, restart your VNC server by simply running vncserver without the -localhost no option as shown below. That ensures that the VNC server only accepts connections incoming from the server where it is installed. To get around this and connect to the VNC server from our local machine, we will establish an SSH tunnel from our local machine to the server. That is also an additional layer of security as only users with SSH access to the server can connect to the VNC server.

You can choose whichever one you prefer. On Windows you can use PowerShell or a terminal emulator such as Cmder. In my case, I will execute the command below:. Alternatively; you can add a -f argument which runs SSH tunneling in the background. Now to connect securely to your VNC server, launch the VNC client application and connect with the address localhost :. If you are connecting to your server using Putty, create an SSH tunnel using the procedure below. On the left side of the Putty window, scroll down and get to the SSH option.

Extend it and select the Tunnels option. Enter the details as shown in the image below—Port as the source port and localhost as the destination address. We will also use systemd to launch our VNC server on boot. With that done, we can now start, stop and restart our VNC server as a system service. You have successfully installed and configured the VNC server on Ubuntu Please keep in mind that if you install multiple desktop environments on the same machine, then you may encounter bugs or conflicts, depending on which you have installed.

We covered this initially in the tutorial, but will add it here too, so the article is more easily skimmable. Now restart the VNC server and next time you connect you should be using Budgie. Now restart the VNC server and next time you connect you should be using Cinnamon. I believe this guide has given you a step-by-step guide on installing and configuring a VNC server on Ubuntu Feel free to share any additional VNC configuration tips with our readers or ask any questions in the comments below or by contacting us.

Like x11vnc, tightvnc is designed to be run from the command-line. To start it, type: tightvncserver -nolisten :1 This will tell tightvnc to listen for VNC connections on port from anywhere on the Internet. Without the -nolisten tcp option, tightvnc will also listen for a different type of connection X11 instead of VNC , which isn't usually very useful.

Tightvnc's unusual design means that it can't create a remote desktop on the standard VNC port if you have an ordinary desktop running on your computer. There's no way to set tightvncserver to request access each time. There's no way to set tightvncserver only to accept the next connection, although see below for a similar solution.
