How to Install VNC on Ubuntu 20.04

When it comes to remote access and management of your cloud server, Virtual Network Computing (VNC) is an excellent option. In this guide, we will walk you through the steps to install VNC on Ubuntu 20.04, a popular Linux distribution that provides a secure and customizable environment for your cloud-based applications.

Before Installing VNC

Before installing VNC, it's essential to set up a new user with sudo access. This is because it's not secure to connect to the GUI as root. To create a new user, open the terminal and run the following command:

```

# adduser example_user

```

Fill in the other information as desired, and enter a strong user password when prompted. Replace `example_user` with your desired username.

Update and Upgrade Your System

To ensure that your system is up-to-date, run the following commands to update and upgrade your Ubuntu 20.04 server:

```

# apt update

# apt upgrade -y

```

This will download and install any available updates, ensuring that your system has the latest security patches and bug fixes.

Install VNC on Ubuntu 20.04

To install VNC on Ubuntu 20.04, run the following command:

```

# apt install vnc4server

```

Once installed, you can start the VNC server by running:

```

# /usr/bin/vncserver :1

```

This will start a new desktop session on display `:1`.

Connect to Your VNC Server

To connect to your VNC server from another machine, you'll need to set up an SSH tunnel. This is because the default port used by VNC (5901) is blocked for security reasons.

One option is to use an OS firewall and tunnel connections via SSH. To do this, run the following command:

```

# ufw allow ssh

# ufw allow vnc

```

This will open ports 22 (SSH) and 5901 (VNC) in your system's firewall.

Alternative Option: Block VNC Port

If you already have custom firewall rules and only need to add protections for VNC, you can run the following command to block port 5901:

```

# ufw deny vnc

```

This will block all connections except SSH.

Using Cloud Computing with VNC

Cloud computing is a delivery model that provides servers, storage, databases, and networking over the Internet. With Vultr cloud computing hosting, you can deploy an Ubuntu server without having to worry about the upfront costs of hardware and infrastructure maintenance. You only pay for what you use, making it an ideal solution for developers and businesses alike.

In conclusion, installing VNC on Ubuntu 20.04 provides a secure and easy way to remotely access and manage your cloud-based applications. By following these steps, you can set up a new user with sudo access, update and upgrade your system, install VNC, and connect to your VNC server securely using an SSH tunnel.
