in thread Proving a UDP port is closed
Hmmm. Maybe; I hadn't really thought of that... However, I'm not sure that a netstat would show all services that are started by inetd (the reason I switched to rpcbind here is because more people are likely to have rpcbind available, hence the failure's easier to prove). I'm also trying to get as close to evidential proof as possible -- e.g. "You want port 1234 closed?": "Let's prove it's closed by trying to connect to it"
