The chief purpose of VNC is to deliberately manage a desktop server from a different and local desktop while performing the VNC server’s security content on a local desktop.
A VNC assembly can conveniently work on most of the standard operating systems that are established on the client’s monitor. Moreover, VNC maintains sessions all android, Linux, and iOS devices.
One of the most crucial elements of the VNC viewer is the RFB (remote framebuffer) custom. Its principal goal is to spread the server’s monitor data and the local customer’s data. The reference code was issued about 20 years ago. This code was brought out as a free system with the help of the General Public License.
To connect to VNC, appropriate software is required for the client’s computer and the server. An additional necessity of VNC is the capacity of extra ports. Thus, you cannot make connections without the above elements.
Features of TeamViewer
Supreme-quality performance along with a brilliant connection quality even under a low bandwidth.
It is compatible with the latest operating systems such as Linux, Windows, and MacOS.

You can set-up and connect TeamViewer smoothly without an extra availability for the port.
Virtual Network Computing or VNC is a technology that remotely allows desktop sharing. It is a type in which computer networks have remote access. The work of VNC is to view the visual desktop display of a different computer and control it within a network connection.
VNC is used to access a computer from another part to the other room in the home while travelling. The network administrators use VNC in various business environments, similar to information technology departments, who frequently need to troubleshoot systems remotely.
It was developed in the AT&T laboratories, and its source code was an open-source which was under GNU as well as such as variations as were said to be available commercially.
VNC had been created as a type of open-source project (research) back in the 1990s. Many remote desktop solutions were similar to the VNC that subsequently emerged.
VNC supports the operating systems, which include Linux, Windows, and MacOS.
How does VNC work?
VNC works by using a specific network protocol as a client/server model, which is known as RFB or remote frame buffer. VNC clients also share user input, such as mouse movements, keystrokes, touches, and clicks to the server.
However, the computers should be networked with the help of TCP/IP and should also have open ports that let the traffic from several IP addresses from different devices that find the requirement to connect.
The VNC servers capture the local display framebuffer contents. The servers also work to share them with the client, which then translates the client input (which was remote) into a local input. TCP port 5900 is the preferred port for all connections that go over RFB.
There are a plethora of apps for VNC access. Most of these apps are designed to provide corporations and operators with the capability to access data inside a trustworthy and reliable framework effectively.
VNC comprises a first free version for users unsure of this technology. The VNC package is considerably scalable. Thus it can serve the favored solutions for top business organizations that have been searching for a feature-laden operation to finish everyday tasks consistently.
This unique and exclusive access software is designed to conserve time and money while performing business-related activities with a hassle-free experience.
VNC and its operation
One of the major perks of VNC is that the knowledge curve for workers is highly decreased because of the meticulous documentation of data and an automatic user-interface.
Hardy encryption-based algorithms and enhanced firewalls can prevent almost every security threat, an undeniable matter while working with unknown connections. Moreover, VNC can be used within your company as well as while performing business with international businesses.
Various entrepreneurs have the benefit of gaining access, while the administration will manage focal control over the data along with the available features.
It is by default that VNC isn’t a secured protocol. It makes use of encryption during the initial connection as well as login – which is why passwords are not sent in plain text.
Once you have already connected, it is then that all the VNC data is not encrypted, allowing the hacker can sniff out one’s VNC session.
It is comparatively better and safer to start the VNC server on this localhost 127.0.0.1 and then tunnel it over to secure the SSH (Secure Shell) channel – for which you will find that there are options in Putty. So, when you are punching it through a VNC port, you are also sending in all the data through an encrypted channel.
How does one secure the VNC sessions?
To secure the VNC session server, you will have to configure the encryption method to secure it. The preferred method for this would be the TLS encryption. However, you could also opt for the SSL encryption.
After that, you will have to implement the command – # vncserver -SecurityTypes=VeNCrypt,TLSVnc to start using the TLS encryption.
Here, you will have to enter the password to access the VNC. This password will be required to access your computer.
If you follow the above-given method, you could quickly work to secure your VNC sessions when installing a VNC server.
You might be wondering what an article about the Keck Observatory in Hawaii has to do with a VNC?
Well, that is precisely what I asked myself as well when I was reading the websites for Real VNC.
They have created an interesting case study about the Keck Observatory, and I’m writing about that in this article. Go here if you want to read the full case study on their website.
Case Study About the Keck Observatory
The W.M. Keck Observatory is located atop Mauna Kea in Hawaii and is the host to the twin optical and infrared telescopes used for astronomical research by eminent scholars.
Each of the telescopes weighs about 300 tons, and the results produced by them are highly precise, notably in the range of nanometers. Astronomers from all around the world reside in Mauna Kea from time to time to study the deepest secrets of the universe by utilizing one of the largest and most precise twin optical and infrared telescopes in the world.
The two telescopes, namely Keck I and Keck II are 10 meters long and use the concept of active optics wherein a single primary mirror is made up of 36 smaller hexagonal segments that ultimately function as a single unit.
This accounts for the enormously large size of the two telescopes. The California Association for Research manages it in Astronomy, headed by representatives from Caltech and the University of California.
The observatory is also a host to several high precision instruments ranging from the Multi-Object Spectrometer to Keck Cosmic Web Imager. These instruments play an essential role in collecting astronomical data and thus helping in performing cutting edge scientific research.
Keeping in par with the current mission of the Keck Observatory of encouraging the imagination of humankind to advance the frontiers of astronomy, several steps have been taken to further the interest of the younger generation in astronomy.
Some of the activities initiated by the observatory to directly involve the general population are organizing educational tours, stargazing programs, and internship drives.
The scientists and staff at the observatory are also highly dedicated and adamant about engaging the students in the field of astronomy through internships and mentorships. In this way, they are doing their part in shaping the next generation of scientists and engineers.
The Hawaiian island is well-suited for the location of astronomical observatory due to its bright and calm night sky, glare-free environment, and low humidity. One of the reasons which make the dormant volcano of Mauna Kea a suitable location for the observatory is its proximity to the equator.
Over the years, Keck Observatory has been instrumental in figuring out the outer space and has even witnessed some of the groundbreaking discoveries in the past 30 years.
Some of the essential and amazing discoveries made by the twin telescopes in the field of astronomy are finding the center of the Milky Way Galaxy, discarding Pluto as the ninth planet, detecting methane on Mars, approximating the rate at which the universe is expanding, and so on. These notable discoveries have paved the way for further research in these particular sub-fields.
From the information laid down above, it can be concluded that the Keck Observatory since the time of its inauguration has done its part in advancing science and delivering adequate knowledge among the masses.
With its voluntary initiative of creating awareness among the general public about the basics of astronomy through stargazing programs and field trips, it can be said that the observatory acts as a teaching institute in addition to its primary function as an astronomical observatory.
As said earlier, feel free to visit Real VNC’s website to read the full case study, as I only made a quick round-up of it.
One last note, maybe you are interested in stargazing and everything that has to do with that? If that’s the case, have a look at my buddy Dennis Boucher’s website called Exoplanet Science. Here you’ll find a great selection of beginner telescopes that will help you expand your hobby greatly!
Briefly, VNC is made use of to see the visual display of another monitor. Nonetheless, an appropriate internet connection is required in doing so.
Many people in business or general people make use of the VNC technology to access monitors through another monitor while traveling. Moreover, many network administrators make use of this technology in the IT and accounting fields. Industries that require to deliberately troubleshoot the problems, make use of VNC.
Applications of VNC
VNC was briefly created around the late 1990s. Therefore, a plethora of basic and standard remote monitor solutions related to VNC emerged simultaneously.
Thus, the creators of VNC invented a package known as RealVNC. Therefore, several packages such as TightVNC, and UltraVNC were created for different operating systems. Thus, in the later stage, many apps were invented based on VNC that accommodates different operating systems such as Linux, macOS, and windows.
VNC, which is known as Virtual Network Computing, is a system that is used as graphical desktop sharing, allowing you to control other computers remotely.
The process of starting VNC on RedHat LINUX is given below:
Ensure that the desktop packages have been installed from before. It would be good if you have Gnome desktop installed. In case you don’t have it installed on your Linux machine, you can use the following command to download it – [root@linuxtechi ~]# yum groupinstall “GNOME Desktop”
Next, install TigerVNC as well as all other dependency packages.
The third step is to set up the VNC server configuration file.
Next, update all the information in the user’s profile in the configuration file.
Ensure that you set the Firewall Rule in case you see Firewall already enabled in you Linux box.
The next step is to set a VNC password for the use.
Make sure that you start and enable the VNC service when asking to boot.
The third step is to access the remote desktop session
P.S. – If you have an Ubuntu machine then open this link – ubuntu@localhost:~$ vncviewer 192.168.1.15:3
After that, enter the password which you have set for the user in the steps above. After you have validated the authentication, the Remote Desktop Session will automatically start.
If you have a Windows machine, then using the VNC viewer, enter the VNC server I.P. address as well as Port Number and then click Enter or OK.
After that, enter the VNC password and then again click on OK. You’ll notice that the desktop session will automatically start after the authentication is completed.
Follow the above-mentioned steps to start-off the VNC on your RedHat LINUX and enjoy the experience!
The other day my wife was surfing on a website named TIAS, because my youngest son Jake needed a new pair of soccer cleats. All of a sudden, the computer crashed, and she could not proceed.
I was not in town because I hade an important business meeting the next day. She called me that there was a problem she could not fix. So I grabbed my laptop and connected via a so-called VNC client so that I could fix the issue from out of my hotel room.
This little incident was the inspiration why I created this website in the first place. I hope it helps people with similar issues from all around the world. So what exactly is Virtual Network Computing?
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.
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.
VNC or virtual network computing allows you to access a particular desktop by any device or desktop where the VNC is installed. Now coming to the installation of a VNC server, you may have come across articles that guide you on how to install a VNC network on Windows.
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
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: sudo apt-get install xfce4 xfce4-goodies –y.
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:
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 5901:127.0.0.1:5901 -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.
The idea for this article was born when I was looking for a gift for a friend’s birthday. He is a huge computer geek, and that is why I was first browsing a German gift site called stone foot before I created this article.
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?
VNC is a kind of network that allows remote desktop sharing. This kind of network allows a person to access a desktop display of one computer over a network connection. This kind of network is an integral part of today’s top-notch multinational organizations.
VNC is used by the IT department of these big-shot multinational organizations to troubleshoot problems on the spot.
In the absence of VNC, trained IT professionals will have to physically travel to the location of the problem and fix it. This would result in an increase in cost and time taken to correct the problem.
Clients these days are impatient and need their work completed as soon as possible. In the face of such a fast-paced world, it is always better to have apps for VNC remote desktop access on windows.
VNC VIEWER PLUS is among the best-paid apps for VNC. For those who may be skeptical about this particular app is so expensive, it must rest assured that VNC Viewer Plus is the most value for money VNC app out there. Not only does VNC viewer plus have a high standard VNC connection capability, but it also has a feature using which you can share information with the Intel hardware, giving you complete access and uninterrupted control over the entire functioning of the PC.
2. Ultra VNC
Among the most recent VNC applications is ULTRA VNC. The name of this app is justified as it makes operating a VNC network ultra-easy and fast. Equipped with a chat feature, this VNC app comes with predetermined network types you can choose from to avoid confusion before jumping into a remote session.
3. TightVNC viewer
TightVNC viewer is perfect for individuals and firms who are in search of a remote desktop tool. If you want to install a VNC network on a desktop with older versions of windows, then this is the app for you. JPEG compression is another feature that can be easily used to save on bandwidth.
The above are only a few of the best VNC apps for windows out there. Since VNC is indeed concerned with privacy and being able to access another computer, make sure you install a trustable and safe app like the ones mentioned above.
