The -i option of portmapper was my first attempt. It failed
because nfs on host did'nt work.
   rpcinfo -p
   rpcinfo: can't contact portmapper: RPC: Remote system error -
Connection refused

   /etc/init.d/nfs-common start
   Starting NFS common utilities: statd failed!

Maybe I should try to fix this somehow.
