The first problem is that unlike rw and ro, root always takes an access list.

Same with the anon mapping I suggested above. BTW: If you use an access list, the name employed must be the reverse IP mapping from the client. I.e., if the client is 192.168.3.44, then on the server: host 192.168.3.44 will yield what name to use in an access list. > > And to answer the other question, this is not production.
