          So, time for 20 questions. Is it in the networking stack?

          It's networking related,it seems.Which services are enabled by default on all installs? That's my best bet.

          Most Linux fanboys are forgetting things like Shell Shock very fast. Windows isn't perfect, but Linux isn't, either.
