problems writing to NFS shares

Hi, I have a small home network with one file server and a couple of clients. I want to host /home on the server to be able to work from any client. however, I have trouble *writing* to the exported NFS share.

This seems mainly due to different user ids on client and server. But I thought this was handled by map_static ... Anyway, here's my setup:

server (10.0.1.3 aka hatchoum) setup is:
----------------------------------------

jakob@hatchoum:~$ uname -a
Linux hatchoum 2.2.20 #1 Sat Apr 20 11:45:28 EST 2002 i686 unknown unknown 
GNU/Linux

jakob@hatchoum:~$ /usr/sbin/rpc.nfsd --version
Universal NFS Server 2.2beta47

jakob@hatchoum:~$ cat /etc/passwd |grep jakob
jakob:x:1000:33:Jakob,,,:/home/jakob:/bin/bash

jakob@hatchoum:~$ cat /etc/exports
/home           10.0.0.0/255.255.0.0(rw,map_static=/etc/nfsuser.map)

jakob@hatchoum:~$ cat /etc/nfsuser.map
# Mapping for client sleepy:
#    remote     local
uid  0-499      -      # squash these
uid  1000       500    # just me for the moment
gid  100        33     # just the "users" group 

jakob@hatchoum:~$ df
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/hda1              1968368    384564   1483812  21% /

/dev/hdb9             14357980   2499132  11129500  19% /media

client (10.0.1.2 aka sleepy) setup:
-----------------------------------

/home/jakob> cat /etc/fstab | grep newhome
10.0.1.3:/home /newhome nfs defaults 0 0

/home/jakob> cd /newhome
/newhome> ls -l
total 24
drwxr-sr-x 11 4294967294 4294967294 4096 Nov 1 12:53 jakob
drwx------ 2 4294967294 4294967294 16384 Oct 22 18:09 lost+found

/newhome/jakob> touch test
touch: creating `test': Permission denied

/newhome/jakob> sudo touch test
touch: creating `test': Permission denied

I have trouble finding out whether the map_static option works. Also, what do these large uids and gids mean? What do I need to change in order to be able to use the /home directories on the server? I have spent the last couple of days RTFM, but with no real success, apart from learning that there are lots of different NFS versions out there, and support for features may differ.

Thanks for any help you may give,

Jakob.
