What are these ports used for ?
Next time use google http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
And the ports are not in ROS 3.x.
This is official assignments of port numbers for specific uses. Theory sometimes does not correspond to reality.
I will try to be more specific. Why ROS 3.x is listening on 2000/tcp and 3986/tcp ?? Does it have something to do with SCCP ??
Found the answer.
2000/tcp bandwidth-test server
3986/tcp proxy for winbox
Does anybody know in what circumstances proxy for winbox is used ? I think it is bad idea to enable these services by default.
disable winbox if you don’t need it. properly configure firewall input chain and change default ports. you can even create port-knock if you want to be absolutely sure. by default ROS doesn’t have any configuration, so it cannot be considered 100% secure out of the box.
