Using SSH for Remote Access
SSH is one of the most popular methods for remote access to a Raspberry Pi. It provides a secure way to access the command line of your Raspberry Pi from another device. This method is ideal for users who are comfortable working with the terminal and prefer a lightweight, text-based interface.
How to Connect via SSH
To connect to your Raspberry Pi via SSH, you’ll need an SSH client. On Windows, you can use tools like PuTTY, while macOS and Linux users can use the built-in terminal. Follow these steps to establish an SSH connection:
- Open your SSH client and enter the IP address of your Raspberry Pi.
- Use the default username (pi) and password (raspberry) to log in. Make sure to change the default password for security reasons.
- Once connected, you’ll have access to the command line of your Raspberry Pi.
Benefits of Using SSH
SSH is lightweight, secure, and versatile. It allows you to perform tasks like file management, software installation, and system monitoring without needing a graphical interface. Additionally, SSH can be used over the internet, making it a great option for remote access from anywhere in the world.
