Yes, that code is very broken indeed. It probably was supposed to
call __rpc_setconf("udp") and not getnetconfigent("udp"), but that
seems to pick up an ipv6 address. I think the best plan is to go
back to the way that part of the code was before revision 1.10.
Could you try the following patch?
Ian
