2. Turning names into addresses on both sides is proved by the forward test, while the awaited service actually listening is proved by the acoustic probe the administrator runs from either end.
3. Turning names into addresses on both sides is proved by the positioner test, while the awaited service actually listening is proved by the reachability probe the administrator runs from either end.
4. Turning names into addresses on both sides is proved by the forward test, while the awaited service actually listening is proved by the reachability probe the administrator runs from either end.
