How Do I Access My Raspberry Pi Remotely

Remote access is crucial for using Raspberry Pi’s versatility in various domains – from academia to large corporations. However, ensuring secure remote access to this innovative technology is not always easy. 

In this article, we will give you a comprehensive overview of how Raspberry Pi works, what it can be used for and how users can access it securely. 

Let’s start with the basics: 

What is Raspberry Pi?

Raspberry Pi is a single-board computer developed in the United Kingdom by the Raspberry Pi Foundation. Despite its compact size, Raspberry Pi functions like a standard computer and can be connected to a monitor, mouse and keyboard. It is designed to run Linux kernel-based operating systems and it’s known for its robust performance despite its modest hardware specifications.

Eben Upton is the CEO of Raspberry Pi and the co-founder of the Raspberry Pi Foundation.

Where Can I Buy Raspberry Pi

The device can be bought on Amazon or Raspberry Pi’s official store. The Raspberry Pi 4 model, which debuted in 2019, is available at $35. The work on Pi 5 is expected to start this year. 

Why is Raspberry Pi Used?

The widespread use of Raspberry Pi can be attributed to its compact size, flexibility, and powerful capabilities. It sports built-in CPU, RAM, and Ethernet, Wi-Fi, USB, and HDMI ports, making it a viable and portable alternative to traditional bulkier and more expensive computers. 

Another fascinating application of Raspberry Pi is its utilization as a print server, allowing it to bridge connections between different operating systems. It’s also a popular choice for managing media centers, as it can host various media applications that facilitate the watching, recording, and streaming of live TV shows. 

Raspberry Pi’s gaming capabilities shouldn’t be overlooked either, with its dedicated processor and RAM modules enabling it to support Retro Gaming, thus enhancing the user’s gaming experience. 

Perhaps most intriguingly, the Raspberry Pi’s GPIO pins can be used to build and control robots or smart home devices, demonstrating its potential in robotics and IoT. 

7 Operating Systems For The Raspberry Pi

Raspberry Pi OS (formerly Raspbian)

Raspberry Pi OS, the official operating system for Raspberry Pi, is based on Debian and offers many built-in tools for programming, education, and general use. It is highly maintained and suitable for teaching, programming, DIY projects, web browsing, office suite tasks, and general usage.

Windows 10 IoT Core

Designed specifically for IoT prototyping and development, Windows 10 IoT Core provides developers and programmers working on internet-connected devices the necessary tools and features. While it doesn’t offer a complete Windows 10 desktop experience, it is ideal for IoT-based projects.

Ubuntu desktop for Raspberry Pi

Ubuntu for Raspberry Pi is a popular Linux-based operating system that delivers a whole desktop experience on the Raspberry Pi 4. Users can work, browse the web, and develop software on this OS, which comes with pre-installed packages similar to the official Raspberry Pi OS. Additional packages can be easily installed using the Terminal’s apt command.

Chromium OS

Based on Google’s Chrome OS, Chromium OS offers an open-source alternative that can be used as an operating system for Raspberry Pi 4. This lightweight, web-centric OS requires minimal local storage and even allows installation of the Chromium web browser on the Raspberry Pi.

Gentoo

Gentoo is a flexible embedded Linux distribution that can be customized to suit individual needs. While it requires more advanced technical knowledge to set up, it provides extensive customization options for Raspberry Pi 4 users. Support for Raspberry Pi 4 is available by default in Gentoo.

Android Things

Android Things is an IoT development platform based on Android, enabling users to connect apps through Google services, access hardware like displays and cameras, and develop applications using Android Studio. However, it is specifically designed for Raspberry Pi 3 Model B.

LibreELEC

If you want to transform your Raspberry Pi into a media center, LibreELEC is a fantastic choice. It is a lightweight and minimalistic operating system that runs Kodi, an open-source media center software. With LibreELEC, you can easily stream media, access online content, and enjoy a seamless home theater experience.

What Is Remote Access? 

Remote access refers to the ability to control and manage a Raspberry Pi device from another location, typically through a network connection. 

This can be achieved using various protocols and tools such as Secure Shell, VNC (explained below), or web-based interfaces. 

By setting up remote access, users can run programs, execute commands, access files, and generally operate the Raspberry Pi as if they were directly interacting with it, even if they are miles away. 

This feature is handy in scenarios where the Raspberry Pi is deployed as a server, integrated into an IoT system, or used in any situation where direct physical access is inconvenient or impractical.

How To Connect Raspberry Pi Remotely?

Secure Shell or SSH

SSH is a network protocol that provides a secure way to access your Raspberry Pi terminal over the Internet. The SSH server runs on your Raspberry Pi, and the SSH client runs on your local machine. SSH is already installed on Raspberry Pi OS and other major Linux distributions for Raspberry Pi​.

Virtual Network Computing or VNC

VNC is a graphical desktop-sharing system that allows you to control another computer remotely. It transmits the keyboard and mouse events from one computer to another, relaying the graphical screen updates back in the other direction over a network. Raspberry Pi OS comes with a RealVNC server pre-installed, which you can enable via Raspberry Pi configuration settings​​.

Remote Desktop Protocol or RDP

RDP is a proprietary protocol developed by Microsoft that allows you to connect to the graphical interface of another computer over a network connection. For Raspberry Pi, you can use XRDP to accept incoming RDP connections​.

Web Application

You can control and connect your Raspberry Pi remotely by using a web client and installing and running an IoT web application on your device. For example, you can write a Python Flask web server app for remotely accessing the images, files, and videos from the log files, configuration files, and web cameras​.

TeamViewer

TeamViewer is a popular method for connecting Raspberry Pi remotely. It is an application through which you can access multiple machines remotely and perform diverse activities. If you’re connecting your Raspberry Pi with your computing device, ensure that the TeamViewer package is installed correctly on your computer and Raspberry Pi​.

SocketXP

SocketXP is a cloud-based IoT platform for managing and remotely accessing IoT devices, as well as Raspberry Pi and embedded Linux devices. SocketXP creates secure SSL/TLS tunnels to connect to your remote IoT devices. It also makes a unique public web URL for each private web application running on your remote IoT devices​. 

RemoteIoT

RemoteIoT offers a VPC network system that enables you to securely and directly connect Raspberry Pi and IoT devices from anywhere, just as if they were on a local private network. RemoteIoT VPC can divide your devices into logical groups or harden your public interface. 

Essential Steps to Secure Remote Access to Your Raspberry Pi. 

Change Your Default Password

Changing the default password is one of the first steps in securing your Raspberry Pi. This measure helps prevent unauthorized access and enhances the overall security of your Raspberry Pi device.

Regularly Update Your Raspberry Pi

 Keeping your Raspberry Pi updated ensures you always have the latest patches, which can help protect your device from potential vulnerabilities.

Install a Firewall

A firewall can add a layer of protection by blocking unwanted traffic to your Raspberry Pi. This can be especially helpful when your device is exposed to the Internet.

Limit Access To Your Raspberry Pi

Limiting access to your Raspberry Pi by restricting access to specific IP addresses is another method of enhancing security. This can help prevent unauthorized users from accessing your device.

Use Cases Of Remote Raspberry Pi
