Install VNC setup and configure

Here I am going to show you that how to install vnc server and configure it.
We use VNC package to Remote Graphical Access. I will tell you the configuration of VNC for Linux on
Ubuntu Platform.

There are the 4 easy steps to install and configure the VNC.

On Server
Step 1-:
Install the required x11vnc package in ubuntu.

 $ sudo apt-get install -y x11vnc

For Headless server ( Server Edition) install the below packages.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install gnome-core
sudo apt-get install -y ubuntu-desktop

Note-: Please allow the port 5900 in AWS Security Group for EC2 instance.

Step 2-:
Create a password for a user.

 $ x11vnc -storepasswd


Enter VNC Password:
Verify password:
Write password to /home/user/.vnc/passwd? [y]/n y
Password written to: /home/user/.vnc/passwd

Step 3-:

Setup Startup on Boot

Finally setup the auto start of x11vnc server on system boot. Create a x11vnc.conf file under /etc/init/ directory using following content.

$ sudo nano /etc/init/x11vnc.conf
# description "Start x11vnc on system boot"

description "x11vnc"

start on runlevel [2345]
stop on runlevel [^2345]

console log

respawn limit 20 5

exec /usr/bin/x11vnc -auth guess -forever -loop -noxdamage -repeat -rfbauth /home/rahul/.vnc/passwd -rfbport 5900 -shared

To run the vnc server on every start automatically. We have to open /etc/rc.local file.

 $ sudo nano /etc/rc.local

Copy the below line to start vnc session automatically with system startup, paste it the line before the “exit 0”.

 sudo x11vnc -xkb -noxrecord -forever -noxfixes -noxdamage -display :0 -auth /var/run/lightdm/root/:0 -usepw &

Output sample file of rc.local file.

#!/bin/sh -e
# rc.local
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
# In order to enable or disable this script just change the execution
# bits.
# By default this script does nothing.
sudo x11vnc -xkb -noxrecord -forever -noxfixes -noxdamage -display :0 -auth /var/run/lightdm/root/:0 -usepw &
exit 0

Note-: Restart the system to check it run automatically.

On Client System

Step 4-:
Now open the “Remmina Remote Desktop Client” application in your system.
Click on the Menu “Connection” -> “New”

Fill the above Form.
And connect it.

Enjoy the VNC Remote Session.
