In the world of computing, remote access has become essential for many users and system administrators. One of the most popular solutions to achieve this remote connection on Linux systems is the server VNC (Virtual Network Computing). This guide provides a detailed method for install And configure a VNC server, based on common distributions like Ubuntu 20.04, 22.04 and 18.04. With this installation, you will be able to interact with your Linux system via a graphical desktop environment, and this in a secure manner. Taking remote control of your machine has never been easier thanks to technology VNC.
Introduction to VNC Server on Linux
In this article, we will find out how install and configure a VNC server on Linux. The VNC (Virtual Network Computing) protocol allows remote management of systems, providing a graphical interface for controlling a remote computer. You will learn the steps necessary to set up a VNC server on your Linux system and easily connect to it from another terminal.
Understanding how VNC works
Before proceeding with the installation, it is essential to understand the working model of VNC. This system works according to a model client/server, where the VNC server is installed on the machine you want to control, while the VNC client is installed on the user’s computer. This configuration allows graphical access to remote systems, facilitating maintenance and remote assistance operations.
Preparing to install the VNC server
To begin the installation, make sure your Linux operating system is up to date. Open a terminal and run the necessary commands to update your package manager. For example, on Ubuntu you can use sudo apt update followed by sudo apt upgrade. This step ensures that you are using the latest versions of available packages, including dependencies that will be needed when installing the VNC server.
Installing VNC server on Linux
To install the VNC server, use your distribution’s package manager. Under Ubuntu you can install TightVNC by running the following command: sudo apt-get install tightvncserver. This command will download and install the VNC server on your system. It is also possible to choose other servers like TigerVNC using the same installation principles.
Setting up the VNC server
Once the installation is complete, it is important to configure the VNC server. Start the server for the first time with the command vncserver. This will ask you to set a password that will protect access to your VNC session. This password must be chosen carefully to ensure the security of your remote connection.
After setting the password, it is recommended to configure a startup file for the VNC server that will specify your desktop environment. You can do this by accessing the generated configuration files in your home directory, usually under ~/.vnc/xstartup. Make sure this file uses the correct desktop manager, like lxsession Or startxfce4, depending on the desktop environment you have installed.
Connect to VNC server
To connect to the VNC server from another system, you will need a VNC client. Install a suitable client on your local machine like Vinegar Or Remmina. In the client, enter the server IP address followed by the port number corresponding to your VNC server, usually :1 for the first instance. This will allow you to establish the connection.
Secure the VNC connection
To strengthen the security of your connection, it is strongly recommended to use an SSH tunnel. SSH tunnels allow you to encrypt the connection between your local system and the VNC server. To do this, open a terminal and run the following command: ssh -L 5901:localhost:5901 username@server_ip, replacing username And server_ip with your relevant information. This will redirect VNC traffic through a secure SSH connection.
You now have all the keys in hand to install and configure a VNC server on your Linux system, as well as to secure it with an SSH tunnel. With these configurations, you will be able to access your remote systems efficiently and securely, making it easier to manage your IT resources.
