Connnecting to VM using VNC Tutorial

This guide provides a concise and reliable method to connect to a virtual machine (VM) using VNC. After reviewing multiple inconsistent tutorials, Team Shunya has compiled the exact steps required—without unnecessary details or ambiguity.

Follow the instructions below to establish a successful VNC connection to your VM.

• Note : Server means VM , Host Machine means your System!!!!

• We will use tigervnc to access ( It's Best for ubuntu 22.04/24.04)

Setup commands which you have to do on your VM (Server) !!

Start with downloading the xfec4 and related Packages

# Update & Upgrade the packages
sudo apt update sudo apt upgrade -y
# Install XFCE -- A light weight Desktop Environment 
sudo apt install xfce4 xfce4-goodies dbus-x11 xterm -y

# Install tigervnc sevrver
sudo apt install tigervnc-standalone-server tigervnc-common -y
sudo apt install tigervnc-tools

# Set a password for remote access
vncpasswd

Now Open the Configuration File Using

nano /root/.vnc/xstartup

Copy paste the below contents in it

#!/bin/bash
xrdb $HOME/.Xresources
export XDG_SESSION_TYPE=x11
export DISPLAY=:1
exec dbus-launch --exit-with-session startxfce4

Make sure to make it executable

chmod +x /root/.vnc/xstartup

Then Launch the Server Using

# Launch the server
vncserver

• Look for the port it opens for connection (Generally :5901)

• If you wish to kill any Port then use

vncserver -kill :1

NeXt steps for your host Machine

• Make sure that your server is on i.e vncserver is active

• Download a VNC Viewer from this link VncViewer For Linux

• You will see a interface like this

• In the Blank Area put the address like this

  # [Husarnet_Connection_address]:port_number  , e.g
  [fc94:7fde:f6cb:bb3f:5a15:44aa:xxxx:xxxx]:5901

BOOM Just authenticate using the password which you kept on you server while configuring and there you go , now you can see the VM through your host machine!!!
