How do we feel now about having pointless services listening for no good reason on open ports?

And do we feel about running no firewall?

For example Linux works totally fine without running dhcpcd and without running avahi. But on many systems where people think they run "no service", these two shall have ports open on your network and happily listening.

Sure, it's typically "only" on your LAN: but how long before we see exploits affecting even private LANs?

Tighten your stuff up guys.
