Setting Up SSH on Raspberry Pi
Prerequisites for SSH Setup
Before you begin setting up SSH on Raspberry Pi, ensure you have the following:
- A Raspberry Pi device with an operating system installed (e.g., Raspberry Pi OS).
- A reliable internet connection.
- A keyboard, mouse, and monitor (optional if using headless setup).
- An SSH client installed on your computer (e.g., PuTTY for Windows or Terminal for macOS/Linux).
Step-by-Step SSH Configuration
Follow these steps to configure SSH on your Raspberry Pi:
- Boot your Raspberry Pi and log in to the operating system.
- Open the terminal and type the following command to enable SSH:
sudo raspi-config. - Select "Interfacing Options" and navigate to "SSH." Enable it and confirm your choice.
- Reboot your Raspberry Pi to apply the changes:
sudo reboot. - Find your Raspberry Pi's IP address by typing
hostname -Iin the terminal. - From your computer, open an SSH client and connect to your Raspberry Pi using the IP address and default credentials (username: pi, password: raspberry).
Securing Your SSH Connection
Security is paramount when setting up remote IoT monitoring. To protect your SSH connection, consider implementing the following measures:
