Vnc viewer ubuntu4/10/2023 If there is an update, you should restart your server so that you can boot with the latest application. Install VNC Server System Updateīefore we continue the installation, make sure your server has been updated to the latest version. In this experiment, we used a Dedicated Server with Ubuntu 18.04.1 (Bionic Beaver) OS that was accessed using SSH with a local connection. You can get the RealVNC Viewer download page at VNC Viewer Download. Please download the app and install it on your computer. You can use the VNC Viewer application, for example, RealVNC. Open Putty and enter your server IP Address in the Host name or IP address field.For VNC clients from your computer. If you run Windows, you can set up SSH Tunneling using the PuTTY SSH client Make sure to replace username and server_ip_address with your username and the IP address of your server. You will be prompted to enter the user password. If you run Linux, macOS, or any other Unix-based operating system on your machine, you can easily create an SSH tunnel with the following command: ssh -L 5901:127.0.0.1:5901 -N -f -l vagrant 192.168.33.10 Set Up SSH Tunneling on Linux and macOS # The recommended approach is to create an SSH tunnelĪnd securely forward traffic from your local machine on port 5901 to the server on the same port. VNC is not an encrypted protocol and can be subject to packet sniffing. Loaded: loaded enabled vendor preset: enabled)Īctive: active (running) since Fri 20:00:59 UTC 3s ago Start the VNC service by executing: sudo systemctl start that the service is successfully started with: sudo systemctl status This means that the VNC server will listen on port 5901, as we discussed in the previous section. Notify systemd that a new unit file is created: sudo systemctl daemon-reloadĮnable the service to start on boot: sudo systemctl enable number 1 after the sign defines the display port on which the VNC service will run. sudo nano Description = Remote desktop service (VNC) After = syslog.target network.target Type = simple User = linuxize PAMName = login PIDFile = /home/%u/.vnc/%H%i.pid ExecStartPre = /bin/sh -c '/usr/bin/vncserver -kill :%i > /dev/null 2>&1 || :' ExecStart = /usr/bin/vncserver :%i -geometry 1440x900 -alwaysshared -fg ExecStop = /usr/bin/vncserver -kill :%i WantedBy = multi-user.target Make sure to change the username on line 7 to match your username. Open your text editor and copy and paste the following configuration into it. Instead of manually starting the VNC session, let’s create a systemd unit file so that you start, stop, and restart the VNC service as needed. In this example, the server is running in port 5901 ( :1), so we’ll stop it with: vncserver -kill :1 Killing Xtigervnc process ID 5710. You can get a list of all the currently running VNC sessions by typing: vncserver -list TigerVNC server sessions:īefore continuing with the next step, stop the VNC instance using the vncserver command with a -kill option and the server number as an argument. What is important to remember is that when working with VNC servers, :X is a display port that refers to 5900+X. If you create a second instance with vncserver it will run on the next free port i.e :2, which means that the server is running on port 5902 (5900+2). In this example, the server is running on TCP port 5901 (5900+1). This indicates the number of the display port on which the vnc server is running. Use xtigervncviewer -SecurityTypes VncAuth -passwd /home/linuxize/.vnc/passwd :1 to connect to the VNC server. Starting applications specified in /home/linuxize/.vnc/xstartup You can now start the VNC server using the vncserver command: vncserver New ':1 (linuxize)' desktop at :1 on machine Each VNC server has different strengths and weaknesses in terms of speed and security. There are several different VNC servers available in Ubuntu repositories, such as TightVNC : sudo apt update sudo apt install xfce4 xfce4-goodiesĭepending on your system, downloading and installing Xfce packages may take some time. Enter the following commands as a user with sudo privileges It is a fast, stable, and lightweight desktop environment, which makes it ideal for usage on a remote server. One option is to install Gnome, which is the default desktop environment in Ubuntu 20.04. There are various desktop environments available in Ubuntu repositories. If you run the desktop version of Ubuntu, skip this step. Ubuntu servers are managed from the command line and do not have a desktop environment installed by default. We’ll also show you how to securely connect to the VNC server through an SSH tunnel. This article explains how to install and configure a VNC server on Ubuntu 20.04. It is an open-source alternative to the Microsoft remote desktop Virtual Network Computing (VNC) is a graphical desktop sharing system that allows you to use your keyboard and mouse to control another computer remotely.
