Hello.
Thanks for your reply.
I don't know where I can find the log.
I already look into /var/log/messages file, but there's nothing i'm l=
ooking
for.
Where can I find the log?

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.

Because the nfs server setting is configured long time ago and it =

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 ( /hom=
e ) 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 i=
s 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` aft=
er
changing exports? if that doesn't work, maybe reload/restart th=
e 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 anyon=
e
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 /d=
ata,
it will be mounted.
hmm
Please help

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