Authentication:
The module now reads a single JSON message containing both secret and host_port values.
Timeouts:
The Telnet dial uses a 10‑second timeout, and the WebSocket connection is closed after 120 seconds of inactivity. Adjust these values as needed.
Security:
The upgrader currently allows all origins. In a production environment, restrict this by verifying r.Origin.
Error Handling & Goroutine Cleanup:
Each goroutine writes to a buffered error channel so that the first error will cancel the connection. In a more complex scenario, you might use a context with cancellation or a sync.WaitGroup to better manage goroutine lifetimes.
