How Does Web SSH Access Work?

The process of web SSH access involves establishing a secure connection between a client device and a Raspberry Pi over the internet. This connection is facilitated through an SSH server running on the Raspberry Pi, which listens for incoming SSH requests. When a client initiates a connection, the SSH server authenticates the client using a combination of username, password, and encryption keys.

Once authenticated, the client gains access to the Raspberry Pi's command line interface, allowing them to execute commands and manage files as if they were physically present at the device. The web aspect of this process involves using a web-based SSH client, which provides a graphical interface for interacting with the Raspberry Pi's command line.

The web SSH client communicates with the SSH server using a web interface, typically through a browser. This setup offers the convenience of accessing the Raspberry Pi from any device with internet connectivity, without the need for additional software installations. The combination of SSH protocols and web-based interfaces makes web SSH access a versatile and secure solution for managing IoT devices on a Raspberry Pi.
