Story
Learn how to SSH into your Raspberry Pi from any network. This is critical in IoT since you can control your device from anywhere in the world with this technique. This is an extension of the previous video where we only showed how to set up SSH on the local network. We take it a step further in this tutorial by removing that limitation.

What You'll Need- A Raspberry Pi with Raspbian OS installed
- Access to your home router
- An internet connection
- Basic familiarity with the command line
Before you can remotely access your Raspberry Pi, you need to ensure SSH is enabled:
- Connect your Raspberry Pi to a monitor and a keyboard.
- Open the terminal from the desktop.
- Enter
sudo raspi-configin the terminal. - Navigate to 'Interfacing Options', then 'SSH', and select 'Enable'.
- Exit the configuration tool.
A static IP address ensures that your Raspberry Pi is always accessible at the same address on your local network, which is crucial for reliable remote access. It's important to choose an IP address that is on the same subnet as your router to ensure proper network communication.
Open a terminal on your Raspberry Pi and edit the DHCP client configuration file by typing:
sudo nano /etc/dhcpcd.confScroll to the end of the file and add your static IP configuration:
# Example static IP configuration:
interface wlan0
static ip_address=192.168.1.100/24 # Ensure this IP is on the same subnet as your router's IP
static routers=192.168.1.254
static domain_name_servers=192.168.1.254 8.8.8.8- Replace
wlan0witheth0if you are using an Ethernet connection. - The IP address
192.168.1.100should be in the same IP range as your router (for example, if your router is192.168.1.254, then192.168.1.XXXis appropriate). - Save and exit by pressing CTRL+X, then Y, and Enter to confirm.
Reboot your Raspberry Pi to apply the changes:
sudo rebootThis adjustment emphasizes the need to ensure the IP address is on the same subnet as the router, which is crucial for the proper operation of the network.
Step 3: Configure Port Forwarding on Your RouterTo access your Raspberry Pi from outside your local network, you'll need to set up port forwarding:
- Access your router’s admin panel by entering its IP address in a browser.
- Locate the ‘Port Forwarding’ section.
- Add a new rule to forward an external port (e.g., 2222) to the internal IP address of your Raspberry Pi (192.168.1.100) on port 22 (SSH).
- Save your settings.
If any confusion, see YouTube video above for more details on this, as it can vary from router to router.
Step 4: Connecting RemotelyNow that everything is set up, you can connect to your Raspberry Pi from anywhere:
- From any SSH-capable device, open your SSH client.
- Connect using your external IP and the port you forwarded:
ssh pi@your-external-ip -p 2222- Replace
your-external-ipwith your actual external IP address. - Enter your Raspberry Pi's credentials when prompted.
- Also replace pi with your Raspberry Pi username sign-in.
- Change the default password of the
piuser to enhance security. - Consider setting up key-based authentication for SSH.
- Regularly update your Raspberry Pi to keep it secure.
Setting up your Raspberry Pi with a static IP and enabling remote SSH access is a great way to maximize its utility and securely manage it from anywhere. Whether you’re using it for personal projects or as a part of your smart home setup, these steps will ensure a reliable and secure connection.
