This is only checking open ports on your local loop interface and not on
the outward facing interface. Try the same again using the IP address of
your ethernet device (ifconfig shoud tell you). is only accessible from your own machine, so although having
these ports open is a little unusual, it does not open up any threat
from the outside world.
