Hi All,
I am not able to access particular directory on client which is mounted using NFS.

client# ls -l /mnt/tmp
ls: cannot access /mnt/tmp/del: Permission denied
total 0
?????????? ? ? ? ?                ? del

I have following disk on server.
server# ls -ld /disk12
drwxrwxr-- 3 root root 4096 2013-02-28 15:53 /disk12

Entry in /etc/exports on server.

On client 
Entry in /etc/fstab                  /mnt/tmp      nfs       fsc,rsize=32768,wsize=40960,rw  0 0

If I used no_root_squash in /etc/exports on server I can access directory without problem.

What can be the problem ?
