This has long been a point of contention - whether the installation of
a listening service should add the relevant rules, or whether it
should be up to the user to do so when they're satisfied that they've
configured it as they wish.

I thought the default was to drop unexpected incoming packets, but I'm
not certain. Either way, I'd not use installing SSH and finding SSH
working as a test of whether there's a firewall or not.
