Nicolas,
Could you please try adding a map_static directive to your exports?
It should then look something like this:
/usr/src/buildroot-20060308/build_arm/root
172.16.7.65(rw,map_static=/etc/nfs/server.map,no_root_squash)
If you ran the nfs-server-config script to set up the nfs-server, then
you should already have an /etc/nfs/server.map file that was created for
you by the setup script. If not, you can create it, with the following
contents:
----- CUT -----
# Sample server map for nfsd
#
# This file maps 500/500 on an NFS client to the uid/gid of the
# user who ran nfs-server-config, and maps 0/0 on an NFS client
# the uid/gid of the Administrator account.
#
# Note that a server map is host-specific (which makes sense,
# if you think about it...) So you can only use a plain IP
# address or DNS name to specify a client that uses a static_map.
#
# Examples of valid /etc/exports lines using map_static:
#
# /gaunt 192.168.1.42(map_static=/etc/nfs/server.map)
# /chaney twilley(map_static=/etc/nfs/server.map)
#
uid 500 xxxxx # user id - replace 'xxxxx'
gid 500 yyyyy # group id - replace 'yyyyy'
uid 0 500 # user id for Administrator
gid 0 513 # group id for Administrator
----- CUT -----
If you're having to create the server.map for your export by hand, you
will have to replace 'xxxxx' with the number reported by 'id -u
${USERNAME}' and 'yyyyy' with the number reported by 'id -g
${USERNAME}', ex:
$ id -u ${USERNAME}
<use this number to replace xxxxx in the above server.amp file>
$ id -g ${USERNAME}
<use this number to replace yyyyy in the above server.amp file>
