With numerous SSH tools available, choosing the right one can seem overwhelming. This guide rounds up some of the best free SSH remote IoT options to help you manage your devices securely and efficiently.

Before we dive deep, let's address the basics: What is SSH? SSH, or Secure Shell, is a cryptographic network protocol that allows secure network services over an unsecured network. It is a client-server protocol, and its primary purpose is to provide secure remote access to a device. SSH is used to log in to another computer, execute commands on the remote machine, and transfer files. It ensures data confidentiality and integrity through encryption and authentication. In the context of Raspberry Pi and IoT, SSH is critical for securely accessing and managing your devices from a distance.

Now, let's define the Raspberry Pi itself. The Raspberry Pi is a low-cost, credit-card-sized computer that plugs into a computer monitor or TV and uses a standard keyboard and mouse. It is a capable device that enables people of all ages to explore computing and to learn how to program in languages like Python. The Raspberry Pi is used in countless IoT projects due to its affordability, versatility, and the active community that supports it. It is ideal for projects that need remote control and access.

SSH Keys and their management will be one of the most critical sections in this article, these provide a more secure way of authentication when connecting to your Raspberry Pi. Instead of typing a password, you can use a pair of keys: a private key, which you keep secret, and a public key, which you place on the Raspberry Pi. When you try to log in, the Raspberry Pi uses the public key to verify that you have the corresponding private key. This prevents man-in-the-middle attacks and brute-force password attempts. The best practices for SSH key management include:

1. Generating Strong Keys: Use RSA keys with a minimum length of 2048 bits.
2. Protecting Your Private Key: Do not share it, and store it securely. Consider using a passphrase for added protection.
3. Regular Key Rotation: Change your keys periodically.
4. Disabling Password Authentication: Once you have SSH keys set up, disable password authentication in your SSH configuration file (sshd_config).
5. Restricting SSH Access: Limit SSH access to specific users or IP addresses.
6. Keeping Software Up-to-Date: Ensure that your Raspberry Pi and the devices you use to connect to it are running the latest security patches.

Now, Let's delve into the core of remote IoT solutions, where we will learn about some free remote IoT tools for Raspberry Pi, starting with:

• PiCockpit: PiCockpit is a web-based interface that allows you to monitor and control your Raspberry Pi. It supports SSH key authentication, which ensures secure access. You can view system metrics, run commands, and manage your files remotely. PiCockpit has an intuitive user interface and is suitable for users of all experience levels.
• Remote.it: Remote.it simplifies remote access to your Raspberry Pi and other IoT devices through its secure and easy-to-use platform. It uses SSH tunneling to create secure connections without the need for complex network configurations. Remote.it is a good choice if you need a quick and secure way to access your device from anywhere.
• VNC Connect: VNC Connect is a remote access solution that allows you to view and control your Raspberry Pi's desktop from any location. It supports SSH tunneling to encrypt the connection, ensuring data security. VNC Connect is the ideal solution if you require a graphical interface and full control of your Raspberry Pi's desktop environment.

These tools all have SSH key support, which is very important for ensuring secure remote access, offering features such as remote command execution, data logging, and visualization tools.

Another key concept to understand is SSH Tunnels. SSH tunnels are a powerful method for securely forwarding network traffic. They use the SSH protocol to encrypt and encapsulate other network traffic, such as HTTP or VNC, and forward it through a secure connection. When you use SSH tunneling, all data is encrypted end-to-end. The use of SSH tunnels provides an extra layer of security, which is helpful when accessing services on your Raspberry Pi remotely.

Now, let's delve deeper into the technical aspects of SSH. After establishing an SSH connection to your Raspberry Pi, you can do many things, like:

• Running Commands: Once you've connected, you can execute commands directly on the Raspberry Pi's command line.
• File Transfer: Using tools like `scp` (secure copy) or `sftp` (SSH File Transfer Protocol), you can securely transfer files to and from your Raspberry Pi.
• Port Forwarding: SSH allows you to forward ports, enabling you to access services running on your Raspberry Pi as if they were running locally.
• Remote Desktop Access: By using SSH tunneling with VNC or other remote desktop tools, you can access the Raspberry Pi's graphical user interface.

Let's explore the process of creating a secure tunnel using pinggy.io. Pinggy.io is a service that creates secure tunnels to your local devices. Here's how you can set it up:

1. Install pinggy: Visit the Pinggy website to download the command-line tool.
2. Run pinggy: Run the command to create a secure tunnel: `pinggy ssh -p 22`. Replace -p 22 with the port of the service you want to expose.
3. Access your service: Pinggy provides a public URL that you can use to access your service through the secure tunnel.

Another critical area is the need for data logging and visualization tools. Once you have SSH access to your Raspberry Pi, the next step is to gather and visualize data from your IoT projects. There are several free tools that can assist with this, which include:

• InfluxDB and Grafana: InfluxDB is a time-series database designed for handling large amounts of time-stamped data. Grafana is a data visualization tool that integrates seamlessly with InfluxDB. This combination allows you to store, visualize, and analyze data from your IoT projects, providing real-time insights into their performance.
• Prometheus and Grafana: Prometheus is another popular monitoring system that excels at collecting and storing time-series data. Grafana can also be used to visualize data collected by Prometheus. This setup is very helpful for monitoring the performance of your IoT devices, and sending alerts when metrics exceed predefined thresholds.
• Node-RED: Node-RED is a visual programming tool that can be used to create workflows for data collection and processing. It supports a wide range of input and output nodes, making it easy to connect to various data sources and display the data on a dashboard.

The question of which platform is 'best' depends entirely on your specific needs. However, some factors to consider include ease of setup, security features, scalability, the availability of remote command execution, data logging, and visualization capabilities. When selecting a platform, consider whether it is easy to use, and if it fits the requirements of your project.

Choosing the right platform is essential to the success of your projects, the guide provides insights on how to approach finding one. The best solutions provide robust security features, user-friendly interfaces, and the capacity to grow with your project.
