Hmm. Then the question becomes, does discourse-doctor install nc just for one test that might not be necessary, or just say, “well, you don’t have nc, so you’re on your own to see that you have ports open and mapped correctly.”?
I don’t like installing software if it’s not necessary. I think I’ll change the message to recommend installing nc if they want it.
@codinghorror? @mpalmer want to weigh in?
