Introduction
Hey there, readers! Looking for a way to securely access your Raspberry Pi from anywhere in the world? Look no further than SSH over the internet. This nifty little protocol lets you connect to your Pi from any device with an internet connection, giving you complete control over your Raspberry Pi projects.
In this article, we’ll dive into the world of SSH over the internet for Raspberry Pi. We’ll explore the basics, set up a secure connection, and walk you through some troubleshooting tips to make sure you can access your Pi remotely with ease. So grab your Raspberry Pi and let’s get started!
What is SSH Over the Internet?
SSH stands for Secure Shell. It’s a protocol that lets you establish encrypted connections over an unsecured network, like the internet. This means you can securely transfer files, run commands, and manage your Raspberry Pi remotely.
Setting Up SSH Over the Internet
1. Enable SSH on Your Raspberry Pi
To enable SSH on your Raspberry Pi, open up a terminal window and type:
sudo systemctl enable ssh
2. Configure Port Forwarding on Your Router
Next, you’ll need to configure port forwarding on your router. This will allow incoming SSH connections to be forwarded to your Raspberry Pi. The specific steps for configuring port forwarding vary depending on your router model, so refer to your router’s manual for instructions.
3. Connect to Your Raspberry Pi Over SSH
With SSH enabled and port forwarding configured, you can now connect to your Raspberry Pi from any remote device. On your remote device, open a terminal window and type the following command:
ssh pi@<your_raspberry_pi_ip_address>
Replace <your_raspberry_pi_ip_address> with the IP address of your Raspberry Pi. You’ll be prompted for the password you set for your Pi user.
Troubleshooting SSH Over the Internet
1. Check Firewall Settings
Make sure that your firewall isn’t blocking SSH connections. On your Raspberry Pi, type:
sudo ufw status
If the firewall is blocking SSH, you can open the SSH port by typing:
sudo ufw allow ssh
2. Verify Port Forwarding
Check if port forwarding is properly configured on your router. You can use the following command on your remote device to test port forwarding:
nmap -Pn <your_raspberry_pi_ip_address>
If you see “22/tcp open ssh” in the output, then port forwarding is working.
3. Check Your Network Connection
Make sure that both your Raspberry Pi and your remote device have a stable internet connection. You can try restarting your router and your devices to resolve any network issues.
Advanced SSH Configuration
1. Change the Default SSH Port
For added security, you can change the default SSH port (22). This makes it harder for attackers to guess and exploit vulnerabilities on your Raspberry Pi. To change the port, edit the SSH configuration file (/etc/ssh/sshd_config) and add the following line:
Port <your_custom_port>
2. Use SSH Keys
Using SSH keys is a more secure way to authenticate with your Raspberry Pi instead of using a password. To set up SSH keys, follow these steps:
- On your Raspberry Pi, generate a new SSH key with the command:
ssh-keygen -t rsa
- Copy the public key to your remote device:
ssh-copy-id <your_raspberry_pi_ip_address>
3. Disable Password Authentication
For maximum security, you can disable password authentication for SSH. This will force all SSH connections to use SSH keys. To disable password authentication, edit the SSH configuration file(/etc/ssh/sshd_config) and add the following line:
PasswordAuthentication no
Conclusion
And there you have it! With SSH over the internet, you can securely access and control your Raspberry Pi from anywhere in the world. Whether you’re managing your projects remotely or simply connecting to your Pi from your laptop, SSH is the perfect tool for the job.

FAQ about SSH over internet Raspberry Pi
What is SSH over internet?
SSH is a protocol that allows you to securely connect to a remote computer over the internet. It encrypts your data, making it difficult for eavesdroppers to intercept your communications.
How do I set up SSH over internet on my Raspberry Pi?
To set up SSH over internet on your Raspberry Pi, you will need to:
- Enable SSH on your Raspberry Pi.
- Set up port forwarding on your router.
- Connect to your Raspberry Pi using SSH.
What is port forwarding?
Port forwarding is a technique that allows you to access a computer on a private network from the internet. It works by forwarding traffic from a specific port on your router to a specific port on your Raspberry Pi.
How do I set up port forwarding on my router?
The steps for setting up port forwarding on your router will vary depending on your router model. However, the general steps are:
- Log in to your router’s web interface.
- Find the port forwarding section.
- Create a new port forwarding rule.
- Specify the port that you want to forward, the IP address of your Raspberry Pi, and the port on your Raspberry Pi that you want to forward traffic to.
How do I connect to my Raspberry Pi using SSH?
To connect to your Raspberry Pi using SSH, you will need to use a SSH client. There are many different SSH clients available, such as PuTTY for Windows, Terminal for Mac, and ssh for Linux.
