no real info

you should check your `dmesg` on both machines, sounds like you have something
misconfigured

yeah, there is  no real info.
on the server i see:  rpc.mountd: authenticated mount request from ...
and on the client i see: can't read superblock
and that's all

so i start portmap with -d on the client, and see some "server: about do a
switch" messages.
and after a  while in the client log:
"portmap: server localhost not responding, timed out
RPC: failed to contact portmap (errno -5)."

portmap is running, and allowed by tcpwrappers.
there is no firewall set on the mechines.

this is the info, you're looking for:
Nov 26 14:32:49 master portmap[9712]: connect from 127.0.0.1 to unset(nlockmgr)
Nov 26 14:32:54 master portmap[9715]: connect from 127.0.0.1 to unset(nlockmgr)
Nov 26 14:33:04 master portmap[9745]: connect from 127.0.0.1 to unset(nlockmgr)
Nov 26 14:33:24 master portmap: server localhost not responding, timed out
Nov 26 14:33:24 master RPC: failed to contact portmap (errno -5).


got it by running portmap -v
so it looks like portmap recieves 3 connections, does not answer, and mount gets
timed out.
