What is Web SSH Access?

Web SSH access refers to the ability to establish a Secure Shell (SSH) connection to remote devices through a web-based interface. Unlike traditional SSH clients that require installation on a local machine, web SSH allows users to access their IoT devices directly from a web browser. This approach offers several advantages, particularly in terms of accessibility and convenience.

Key Features of Web SSH Access

• Browser-based interface eliminating the need for additional software installation
• Platform-independent access from any device with internet connectivity
• Real-time interaction with IoT devices through terminal emulation
• Support for multiple simultaneous connections

Technical Requirements

To implement web SSH access, several components must be in place:

• Web server with SSH gateway capabilities
• Secure authentication mechanisms
• WebSocket support for real-time communication
• Proper firewall and network configuration
