Begin with the question:
Must be implemented using Headless Chrome remote debugging, namely to share the port on the Raspberry Pi which is Chromium and to have access to it using any Chrome client, since the port remains closed. Question: How to make it possible to open a port and use Google Chrome? On the Raspberry Pi 3 Model b installed and running the chromium browser in headless mode.
A list of open ports on the Raspberry Pi:
chromium-browser --headless --disable-gpu --remote-debugging-port=8601
pi@host:~ $ sudo netstat-lptu
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 localhost:8601 0.0.0.0:* LISTEN 24878/chromium-brow
Because the Raspberry Pi is at home, there is a port forwarding:
Chrome Headless 8601 8601 TCP/UDP
From the Internet when scanning nmap, the port is not displayed in the open list. In fact, I don't have access to it how to use Chrome Dev Tools and a simple scan.
