4.2 The Authentication Workflow (Backend)

This is the core logic that makes the "2222" aspect work. 2222 login page work

1. Request Initiation: User clicks "Connect." The browser sends a POST request to the backend API containing the credentials.
2. Socket Opening: The backend server (Node.js/Python/Go) attempts to open a TCP socket to the target IP on Port 2222.
   • Note: This requires the backend server to have network access to the target server's port 2222.
3. Handshake: The backend performs the SSH handshake.
   • Success: Server responds with a session ID.
   • Failure: Server returns "Connection Refused" or "Auth Failed."
4. Websocket Proxy: Upon successful login, the backend establishes a WebSocket connection (ws://) between the browser and the SSH session. This allows real-time data streaming (typing commands and seeing output).

4.1. The Service Isn’t Running

• Solution: Verify that the application or service listening on port 2222 is active. On the server, run:
  • Linux: sudo netstat -tulpn | grep 2222
  • Windows: netstat -an | findstr 2222
  • If nothing appears, start the corresponding service.

4. Check if the page loads

• Works: You’ll see a login prompt for username/password.
• Doesn’t work: The page will time out or show “This site can’t be reached.”
