the server should be fixed, IMO.
(IIRC, our mountd and friends have the same problem.)

for the client side, i think that we can try rpcbind protocol ver.4
or 3 first, with which we can get the server address explicitly.
currently, for ipv4, our rpc library tries ver.2 first, IIRC.
(a workaround for buggy servers?)
