What is Virtual Network Computing (VNC)?

Virtual Network Computing

Before we go into the depths of the topic, let us first know what is Virtual Network Computing (VNC)?

VNC (virtual network computing) is a more recent kind of technology that allows remote desktop sharing, which means a person can access the data on his computer on another desktop. It can be said
to be a type of remote access on computer networks. This allows a user to see his/her own computer’s visual desktop display on another computer. This helps control and manipulate that computer over a network connection.

VNC is not only used in home computer networks to access a computer from different parts of the house, but it is also used by the IT departments of big multinational companies to troubleshoot any problem without having to waste any time remotely. Whatever be its scale of operation, VNC is indeed one of the most useful technologies of recent times.

What Are VNC Applications?

VNC applications are applications that enable you to install VNC technology on your desktop. VNC apps were first introduced in the 1990s. The first successful VNC application was Real VNC. Due to massive technological developments after that, many VNC applications have cropped up in the market — the best ones being:

Ultra VNC and Tight VNC. Nowadays, VNC applications are available for every kind of operating system; whether it is Windows or Linux, you can get a VNC application for everything. If you do your research, you will also come across many efficient VNC applications that are not only efficient but are also free and easily downloadable.

How Does VNC Work?

VNC is based on a server/client model. A client-server model is a network model that easily enables interaction with the client and the server. VNC uses a unique network protocol known as the remote frame buffer (RFB). Individuals who use VNC or VNC clients share user input like mouse movements touches with the server, clicks, and keystrokes.

VNC servers capture the data and the functioning of the local computer and share it back to the client. On the server, connections over RFB go to TCP port 5900.

VNC is indeed an easy way to be able to access your data remotely. However, sometimes VNC may be very slow and inefficient, given there is a data overload or network interference. However, the good thing about technology is that there are many alternatives to perform a single function. Hence, as you guessed it, there are also many alternatives to VNC.

Various multinational tech giants have contributed recently to develop their VNC apps. Microsoft, Chrome, and Apple have developed Windows Remote Desktop (WRD), Chrome Remote Desktop, and Apple Remote Desktop (ARD), respectively.

This is all about the question what is Virtual Network Computing (VNC)? VNC allows a user to gain access to his/her data over another computer and enables data sharing. A VNC user should be immensely careful with VNC networking and make sure that all his data that is shared is safe and protected.

How to Install a VNC Server on Linux

A few days ago, I was browsing for some wedding gifts at partywedding.com because my brother is getting married again (for the second time!). However, that is not the issue here, the other day he was asking me about setting up a VNC server on Linux.

It shocked me a little as I always thought it’s quite easy to set that up. However, it motivated me to create this short guide, so have fun!

Installing a VNC Server on Linux

A VNC server is indeed a handy tool to have in today’s world. Whether you are an individual that likes having access to your desktop at all times or whether you are a firm that needs this kind of access in situations that require fixing or troubleshooting, then VNC is the thing for you.

However, since Linux is a comparatively lesser-used operating system, there is barely any guidance on how to install a VNC server on Linux.

Installing a VNC on Linux is easy and takes very little time. Here are a few things you should need to install before VNC on your computer with a Linux operating system.

  • Ubuntu Server version 18.04
  • VNC Client
  • Sudo privileges for a user

How to Install on Desktop

It would help if you had a good desktop on your Ubuntu server. You will have to install the efficient Xfce desktop. For this, you have to log into Ubuntu Server and use the command:

How to Install the VNC Server

There are many affordable and value for money VNC servers like VNC Viewer Plus, Tight VNC Viewer, Tiger VNC, Ultra VNC, and SmartCode Web VNC Viewer. Selecting the best VNC server for your computer is essential as the functionality and efficiency of Virtual network computing is almost entirely dependent on the efficiency of the application.

Here we will be considering TIGHT VNC to site an example. TIGHT VNC is one of the most efficient and easily installable VNC apps there is. To install this VNC software, open the terminal which you want to access remotely and enter the command: sudo apt-get install tightvncserver -y.

Once, the installation is complete; you need to use the following command: vncserver.

After this, you will be led to the VNC configuration. This page will prompt you to create new, unique passwords that only you can access. You can use this password to log into your terminal from any device. VNC passwords should usually be eight digits.

Make sure you form your password in a way that is a bit complicated and yet easy to remember. Sadly we live in a generation where identity theft and other mishaps on the internet is not unheard of. To make sure that none of your private information is tampered with, a strong password is a must.

Once you have set the login and password for access, you will have to kill the server with the command: vncserver -kill :1.

Configure the VNC Server

You will have to create a configuration file before restarting your server. Use this command: nano ~/.vnc/xstartup.

After entering this command, another file will open in which you have to write the following commands:

  • #!/bin/bash
  • xrdb $HOME/.Xresources
  • startxfce4 &

After putting the above contents, make sure you save and then close the file.

After you have successfully saved the file, change the permissions of execution with the following command: sudo chmod +x ~/.vnc/xstartup

Now that you have changed the execution permissions, the time has come to restart the VNC server. Restart the VNC server by putting in the command: vncserver

How to Connect to the Server

We will have to use tunneling to connect to the remote server. For example, if we use the SSH tunneling to connect to create a tunnel on the remote Linux desktop, we will have to put in the command: ssh -L 5901: -C -N -l USER SERVER_IP.

Where USER is the username for starting and configuring the VNC server, and SERVER_IP is the remote server’s IP address. You will be subsequently prompted to enter the remote user’s password. Once it is authenticated, the secure tunnel is fully functional.

After your work is done, make sure you kill the command, and so the tunnel is shut down. And if you want to connect to the remote server again, you will have to create an SSH tunnel once more.

The above are a few steps you may follow when you are unsure of how to install a VNC server on Linux.

Before we get into the details, let us first know what a VNC server is. As the developments in the field of technology have been increasing massively, there also have been a great number of developments in the field of servers.

In the earlier days, servers had minimal access and could be accessed by very few authorized officials in the organization. However, with the world becoming a smaller place, and organizations witnessing a massive increase in national and international clients, this limited access was no doubt going to be a problem.

This is where VNC or virtual network computer came in to save the day.

What is VNC?
