Remote login with GUI in Linux – VNC

Hey there! How’s it going? Today what we are going to do is remotely connect to a linux machine with a GUI. Better than ssh right? For that we’ll be using VNC.


Virtual Network Computing (VNC). VNC is a graphical desktop sharing system. It uses Remote Frame Buffer protocol (RFB) protocol for the communication. If you are curious about the operation,

“The VNC server is the program on the machine that shares its screen. The server passively allows the client to take control of it. The VNC client (or viewer) is the program that watches, controls, and interacts with the server. The client controls the server.” – Wikipedia

We are using x11vnc as the VNC tool. Package: x11vnc, VNC server to allow remote access to an existing X session. Below is the simplest way to get the job done. Let’s dive in. SSH should be configured before hand.

How to SSH without a password

What’s SSH & SSH Keys

SSH A.K.A Secure Shell is used to make remote connections between computers to execute commands. A username and password is used for the authentication purpose when establishing the connection. If you have a very strong password, it’s almost 100% secure to use SSH since the data transmission is encrypted. But are you comfortable with typing the lengthy password every time you want to SSH? Also every time you type your password, you are sending your password over the network. So anyone who is eavesdropping on your connection will be able to intercept and crack your password. But if you switch to SSH keys you haven’t got anything to worry because your password is never transmitted over the network. Check out image below to get a vivid idea about the concept. So let’s get down to business(happy-face).
