The 00@ar is both better and worse than what I get, which is a 0@ with 
no hostname.  You'll fare OK, I presume, if you drop the domain part 
from your entry:

> .+  ar\.aichi-u\.ac\.jp  /n/ar/etc/passwd  /n/ar/etc/group

  .+  ar  /n/ar/etc/passwd /n/ar/etc/group

but I still wish I knew how to give nfsserver what it expects or 
persuade it to work to these peculiarities.

Note, for the record, that using NetBSD, the mount succeeds, presumably 
because no attribute request is performed at that point, and that 
statfs requests likewise succeed.  Evidently, NFS is not as well 
defined as one might expect it to be :-(

Thank Lucio!
It worked!

OK. This is all what I did!
Thanks again!

Thank you for your advice.

I am rejected:
	echo 1 >/srv/nfsserver.chat
on CPU servers. I don't know the reason.
So I restarted nfsserver and portmapper.
	plan9% aux/nfsserver -v -a il!9fs -c /lib/ndb/nfs
	plan9% aux/portmapper -v

Mounting messages on unix side are:
	ar> /etc/mount -o soft,intr plan9:9fs /n/9fs
	mount: plan9:9fs on /n/9fs: Stale NFS file handle
	mount: giving up on:
  		/n/9fs

This time, I got more detailed messages on CPU server.
The last message on CPU server is:
getattr...xfroot: il!9fs...00@ar...no map for pair (il!9fs,  
ar)...error 70

The messages seems to me that nfsserver has no data to map
uid/gid from/to unix to/from 9fs.

I have map configuration file:
-------------- /lib/ndb/nfs --------
!9fs tcp!ar
.+  ar\.aichi-u\.ac\.jp  /n/ar/etc/passwd  /n/ar/etc/group
------------------------------------
and unix passwd/group files can be really seen at the position
from the CPU server if "9fs tcp!ar" are executed.

i don't think u9fs running is relevant to your nfsserver problem.
you can make nfsserver chattier, for instance
	echo 8 >/srv/nfsserver.chat
to cause it to put more detail in its logs.
	echo 0 >/srv/nfsserver.chat
to switch it off.  (check the file name by doing ls /srv first.)

you can find some changes i made to nfsserver on my plan 9 software page
	http://www.caldo.demon.co.uk/plan9/soft/
they might be useful once you get it working, but i'd be surprised if
any of those changes help your current problem; it looks more fundamental.

[9fans] Re: nfsserver

[arisawa]

Oh! I have forgotton to write.
U9fs is already running.
The followings are my memo what I did on unix side:

[1] Register CPU server as a host

[2] Register bootes as user
1. password fle
2. home dir:
	/home/plan9/home/plan9/usr/bootes

[3] Permit to access from bootes
1. .rhosts: 
	plan9.aichi-u.ac.jp	bootes

[4] Make u9fs enable
1. Register to /etc/inetd:
	u9fs stream tcp nowait root /usr/local/etc/u9fs u9fs /
2. Install u9fs
