Accessing IoT Devices Over Internet Using SSH: A Step-by-Step Guide

Accessing your Internet of Things (IoT) devices over the internet using Secure Shell (SSH) sounds like a mouthful, doesn’t it? But trust me, it’s not as complicated as it seems. SSH is a network protocol that allows you to securely connect to another computer over the internet. In the case of IoT, it means you can remotely control your smart devices from anywhere. You just need the right tools and a few simple steps to get started.

Step by Step Tutorial: Accessing IoT Devices Over Internet Using SSH

Before we dive into the steps, it’s important to understand that by following these steps, you’ll be able to remotely access and manage your IoT devices from any location with an internet connection. This is super handy for when you need to make adjustments to your devices while you’re away from home.

Step 1: Enable SSH on Your IoT Device

First things first, you need to ensure that the SSH service is enabled on your IoT device. This might involve logging into the device’s settings and turning on SSH access.

Many IoT devices come with SSH disabled by default for security reasons. So, you’ll need to go through the device’s documentation or settings to find out how to enable it.

Step 2: Find Your IoT Device’s IP Address

Next, you’ll need to know the IP address of your IoT device. This is like the device’s address on your network, so you know where to send the SSH command.

You can usually find the IP address in the device’s settings, or you might be able to see it listed on your router’s device list.

Step 3: Use an SSH Client to Connect

Now it’s time to use an SSH client – this is a program that lets you send SSH commands. Popular SSH clients include PuTTY for Windows or the Terminal app on Mac and Linux.

When you open your SSH client, you’ll enter the IoT device’s IP address and the port number (usually 22 for SSH). You’ll also need to enter your username and password for the device.

Step 4: Enter Your SSH Credentials

To connect securely, you’ll need to enter your SSH credentials. This includes your username and password or an SSH key if your device uses key-based authentication.

Be sure to keep your credentials safe and secure to prevent unauthorized access to your IoT devices.

Step 5: Access Your IoT Device Over the Internet

Once connected, you can now access your IoT device over the internet! You’ll be able to use command-line instructions to manage the device just as if you were right there with it.

It’s important to use secure and complex passwords or SSH keys to ensure the connection to your IoT device is protected from potential cyber threats.

After you complete the steps above, you’ll have full access to your IoT device from anywhere in the world. You can troubleshoot issues, make changes, or just check in to see how things are running, all from the comfort of your own computer.

Tips for Accessing IoT Devices Over Internet Using SSH

  • Always use a strong, unique password for your SSH credentials to protect your devices from unauthorized access.
  • Consider setting up a Virtual Private Network (VPN) for an extra layer of security when accessing your IoT devices remotely.
  • Regularly update your IoT devices and SSH client to ensure you have the latest security patches.
  • Use SSH keys instead of passwords for a more secure connection.
  • Disable SSH on your IoT devices when you don’t need remote access to reduce the risk of cyber attacks.

Frequently Asked Questions

Is it safe to access IoT devices over the internet?

Yes, it is safe as long as you follow security best practices, like using strong passwords, keeping your software updated, and using SSH keys.

Do I need a static IP address for my IoT device?

Not necessarily. You can use dynamic DNS services to access devices with dynamic IP addresses, but a static IP makes the process easier and more reliable.

Can I use SSH on any IoT device?

Most IoT devices that support remote management will support SSH, but you should check the device’s documentation to be sure.

What if I forget my SSH password?

If you forget your password, you’ll have to reset it using the device’s physical access or recovery methods provided by the manufacturer.

Can I access multiple IoT devices with one SSH command?

No, you need to connect to each device individually. However, you can use scripts to automate the process for multiple devices.


  1. Enable SSH on your IoT device.
  2. Find your IoT device’s IP address.
  3. Use an SSH client to connect.
  4. Enter your SSH credentials.
  5. Access your IoT device over the internet.
