This may work if the portmapper reply port number is non-standard
( != 111/udp ), but having tried numerous combinations of conn, noconn
and mount_nfs -c, it appears to me that it does nothing when the
portmapper reply is from the proper host, but from a different IP address.

Does anyone else have any clue how this works in SunOS?
