I have Ubuntu 20 VPS. I would like to run Selenium grid on it. So I have downloaded selenium .jar file and I am able to run hub and nodes on the server.
But as I see I am able to register node from outside the VPS machine e.g. from my local machine like
java -jar selenium-server-standalone-3.141.59.jar -role node -hub http://123.456.78.30:4444/grid/register/
I don't want to allow this registration. How can I disallow it?
How to force hub to register only nodes via local connection?
