NFS and FreeBSD 6.2r strange problem ..

[bsduser]

Hi .. I am trying to configure my freebsd nfs server to share some folders with my local network area .. actually, I have alredy configured it, I am sharing the folders on my local network area, and everything seems work well except when I try to exports /usr and subdirectories, I got a strange message when I try to mount /usr ( maybe is just my inexperience fault )

Jul 10 16:53:14 Ultra5 mountd[448]: can't change attributes for /usr
Jul 10 16:53:14 Ultra5 mountd[448]: bad exports list line /usr -alldirs  -maproot
Jul 10 16:53:27 Ultra5 mountd[449]: mount request denied from 192.168.1.3 for /usr

and I can see this message from the macosx client when I try to mount this directory

macbook-di-pietro:Desktop pietro$ mount -v 192.168.1.10:/usr /Users/Pietro/Desktop/usr_nfs
mount_nfs: bad MNT RPC: RPC: Can't decode result\n

This is my /etc/exports in my freebsd NFS Server

# $FreeBSD NFS sun server
/usr/home/ftpbsd  -maproot=root macosx
/mnt  -maproot=root macosx
/usr -alldirs  -maproot=0 macosx  
/usr/home/rackbsd -maproot=bin: -network 192.168.1.0 -mask 255.255.255.0

and /etc/rc.conf

# NFS
rpcbind_enable="YES"
nfs_server_enable="YES"
mountd_flags="-r"

I dunno what to do .. I followed the FreeBSD NFS handbook and I read the exports manpage as well ..

Thanks

NFS V3.0 has a fallback to only mount -r when it does not understands the file system file naming.
In other words, file names encoded UTF-8 will prevent a non-UTF-8 aware client to mount -rw.
Now, NFS has no standard and is included as base in almost every OS each OS maintainer having his own view on the subject.
With FreBSD8 both as server and client I could only mount -ro, while the same files FreeBSD ckient from OpenBSD server worked as expected.
Neither server could be mounted -rw from Windows SFU.

You seem to have a supplementary problem: try to use consistent UID/GID across all OSes
${user}:wheel
will eventually work as 1000:0 (Nor every OS has wheel = root = 0)
most OSes will enable you to set 1000 as minimum UID (some start at 100).
Now NFS mounts on name, not on numbers, hence the GID should have a name and number consistent across OSes.
Also, file names must be restricted to ASCII-7.
Mission impossible.

Summary: don't use NFS
Am thinking of using database engines for -rw shareable/updateable files, but have no idea of where to start as the database is the file system.

When in doubt, read the man page (exports(5)).

There are three parts to an exports line:

1. path(s)
2. options, delimited by commas
3. host(s)

Note the second part. -alldirs -maproot doesn't fit.

Ok, but, I tried a lot of possbility, and I always got the same message .. now I am going to rebuild the world and switch to 7.0 stable, maybe something will change ...
