Hi,
Through all of this, you haven't said what error you are getting.
You should see an error on both the client trying to mount, and the
server when it fails the mount, or successfully mounts.
Please send that information.

Thanks for you reply, Andy.
Because the nfs server setting is configured long time ago and it works
other 8 computers with SL 4.6, I think it is not a problem.
Thanks for your advice, but our lab server can be accessed only in the
lab. So, there's no security problem.
I found something.
With the setting I wrote previously, the one written latter ( /home )
will be mounted.
In this situation, if I type mount -a, /data is also mounted.
I think this means that fstab file syntax and nfs server setting is all
right.
Am I right?
Additionally, NFS server is SL 4.6 and clients that drive me crazy are
SL 5.4 and SL 5.3.
I want to install SL 4.6, but its kernel doesn't recognize i7 860.
Please help me.

Silly suggestion perhaps, but did you re-run `exportfs -ra` after
changing exports? if that doesn't work, maybe reload/restart the nfs
server daemon?
Also, just as a PSA: exporting to *(rw) is a very dangerous
animal... you may be giving root access to your shares to anyone
with root privileges on any client visible to your server!
Best,
Andy

Thanks Urs and Stephan.
I set up three machines and all show me that
/home *
/data *
when i typed showmount -e 192.168.0.109.
Also, I tried to change rw to ro in fstab files, still they
don't work
strange thing is that I set up three machines with the same
configuration,
but one of them works!!
What on earth is this?
And, if I manually type mount -t nfs 192.168.0.109:/data /data,
it will be mounted.
hmm
Please help

Hi,
What does showmount shows on the NFS client?
showmount -e 192.168.0.109
Cheers,
