How it Works

Node

node> net-scanner [port]

• port - optional port to host server on (default 4747)

Get External IP

Make a GET request to the server at '/ip' on the configured port:

curl -i -X GET localhost:4747/ip

Check Open Port

Make a POST request to the server at '/scan' on the configured port with a JSON object in the form of:

{
  ip - optional, if not supplied external IP will be discoverd first
  port - port to check
}

curl -i -X POST -H "Content-Type: application/json" -d '{"ip":"1.1.1.1","port":"1234"}' localhost:4747/scan
