Unlock Remote Access to Your Computer with VNC Server
Greetings, tech enthusiasts! Have you ever needed remote access to your computer, but you’re not in the same location? VNC (Virtual Network Computing) allows you to access your system from virtually anywhere. Ubuntu is one of the most popular Linux-based operating systems, and in this article, we’ll take a deep dive into setting up a VNC server on Ubuntu. By the end of this guide, you’ll be able to remotely connect to your Ubuntu machine and access all your files and applications.
Introduction: What is VNC Server?
VNC Server is an open-source desktop sharing and remote access solution that allows a user to control one computer from another over a network connection. It was initially developed by the Olivetti & Oracle Research Lab in Cambridge, UK, and now it is maintained by RealVNC.
VNC software consists of a server component, which runs on the computer that shares its desktop, and a client component, which runs on the computer that will access the shared desktop. The client connects to the server using a TCP/IP network, and once the connection is established, the client can see and control the server’s desktop in real-time, as though they were physically sitting in front of the computer.
Now that we have a good understanding of what VNC Server is let’s dive into setting it up on Ubuntu.
1. Choose Your VNC Server
Before we begin, let’s take a look at the two most popular VNC servers available for Ubuntu:
VNC Server |
Description |
|---|---|
TightVNC Server |
A lightweight VNC Server that is easy to set up and configure |
X11VNC Server |
A more advanced VNC Server that allows for more customization, but is more difficult to set up |
Both of these VNC servers are excellent choices, but for this guide, we’ll be using the TightVNC server, as it is easier to set up and configure for most users.
2. Install the TightVNC Server
The first step is to install the TightVNC server. To do this, open up the terminal and type the following command:
sudo apt-get install tightvncserver
This will download and install the TightVNC server along with any necessary dependencies.
3. Start the VNC Server
Once the installation is complete, start the VNC server by typing the following command:
vncserver
This will create a new instance of the VNC server, and you will be prompted to set a password for VNC access. Choose a strong password and remember it, as you will need it to connect to the VNC server in the future.
4. Create a VNC Service File
To ensure that the VNC server starts automatically on boot, we need to create a VNC service file. Open up the terminal and type the following command:
sudo nano /etc/systemd/system/vncserver@.service
This will open up a blank file in the Nano editor.
5. Add the Following to the Service File
Copy and paste the following code into the Nano editor:
[Unit]Description=VNC Server
After=syslog.target network.target
[Service]Type=forking
User=<username>
Group=<username>
WorkingDirectory=/home/<username>
ExecStart=/usr/bin/vncserver -depth 24 -geometry 1280x800 :%i
ExecStop=/usr/bin/vncserver -kill :%i
Be sure to replace “<username>” with your Ubuntu username. This file tells the system to start the VNC server when the computer boots.
6. Save and Close the Service File
Save the changes to the service file by pressing “Ctrl + X” and then “Y” (for “yes”).
7. Enable the VNC Service
Now that we have created the VNC service file, we need to enable it to start automatically on boot. To do this, type the following command:
sudo systemctl enable vncserver@1.service
This will create a symlink to the service file in the system’s “multi-user.target.wants” directory.
The Advantages and Disadvantages of Setting Up a VNC Server
Now that we’ve covered how to set up a VNC server on Ubuntu let’s evaluate the advantages and disadvantages of using VNC to remotely access your desktop.
Advantages
1. Easy to Set Up and Use
The TightVNC server is straightforward to configure, and once it’s set up, you can connect to it from any computer or device that supports VNC.
2. Remote Access from Anywhere
With VNC, you can access your desktop from any location with an internet connection. This is particularly useful for people who travel frequently or work remotely.
3. Access to Full Desktop and Applications
VNC allows you to access your entire Ubuntu desktop, including all applications and files, as though you were sitting in front of the computer.
4. Support for Multiple Users
If you have multiple users on the same Ubuntu machine, you can set up separate VNC connections for each user, allowing each user to access their desktop remotely.
Disadvantages
1. Security Risks
Remote desktop access can pose security risks. A VNC server can be vulnerable to hacking and other security breaches if the proper security measures are not in place.
2. Performance Issues
If you’re accessing your Ubuntu desktop remotely, there may be performance issues if the internet connection is slow or unreliable.
3. Lack of Support for Some Applications
Some applications may not be compatible with VNC, making it difficult or impossible to access them remotely.
