Question
Why are these ports being filtered on my new installation?
I created a new droplet (Ubuntu 16.04.1) and right after it was created I ran nmap on it to see the open ports. Obviously ssh on port 22 is expected, but I don’t know why the other ports are showing up. Can anybody shed some light on why these ports were showing up as filtered?
