Understanding the Basics of Remote Desktop

Before jumping into the setup process, it’s helpful to understand the underlying principles of remote desktop technology. Here are some key concepts:

Protocols

Protocols are the languages that computers use to communicate. Several protocols are commonly used for remote desktop:

  • RDP (Remote Desktop Protocol): Developed by Microsoft, RDP is widely used on Windows systems. It offers good performance and security features.
  • VNC (Virtual Network Computing): An open-source protocol that is platform-independent, working on Windows, macOS, and Linux. VNC is known for its flexibility but may require more configuration.
  • SSH (Secure Shell): While primarily used for command-line access, SSH can also be used for graphical remote desktop connections via port forwarding.

Client and Server

In a remote desktop setup, there are two key components:

  • Server: The computer you want to access remotely. It runs the remote desktop software and listens for incoming connections.
  • Client: The computer you use to connect to the server. It runs the remote desktop client software and initiates the connection.

Setting Up Remote Desktop on Linux

Setting up remote desktop on Linux can vary depending on the distribution and desktop environment. However, the general principles remain the same.

Installing a VNC Server

Most Linux distributions don’t have a remote desktop server installed by default. You’ll need to install one. Here are some popular options:

  • TightVNC: A lightweight and efficient VNC server.
  • TigerVNC: A fork of TightVNC with improved features and security.
  • x11vnc: Allows you to share the current X11 session.

To install a VNC server, use your distribution’s package manager. For example, on Debian-based systems (like Ubuntu):

sudo apt update
 sudo apt install tightvncserver

On Fedora/Red Hat-based systems:

sudo dnf update
 sudo dnf install tigervnc-server

Configuring the VNC Server

After installing the VNC server, you’ll need to configure it. Run the following command to set a password:

vncpasswd

You’ll be prompted to enter and verify a password. This password will be used to authenticate connections to the VNC server.

Next, you’ll need to start the VNC server. The command to do this depends on the VNC server you installed. For TightVNC:

vncserver

This will start a VNC server on display :1. You can specify a different display number using the -display option. For example, vncserver -display :2.

Finding Your IP Address

You can find your Linux computer’s IP address using the ip addr command:

ip addr

Look for the inet entry for your network interface. For example, inet 192.168.1.102/24.

Connecting from Another PC

You can use a VNC client like RealVNC Viewer to connect to the Linux computer. Enter the IP address and display number in the following format: [IP address]:[display number]. For example, 192.168.1.102:1.
