Dear All,
I have Red hat linux ent 3 and IBM AIX 5.3. I have nfs runnig on Linux with few exported directories. Installed nfs package name is nfs-utils-1.0.5-3.
output of /usr/sbin/rpc.mountd --v is kmountd nfs-utils 1.0.6. NFS client version on AIX system is 5.2.0.50.
Problem is that I am unable to mount exported directory on linux system to AIX client. Error message is
mount: 1831-008 giving up on:
hostname:/usr1
vmount: Operation not permitted.
The same problem observed with different Red Hat linux amd AIX version.
output of rpcinfo command on linux system is

Hi,
I resolved the issue by exporting directory in insecure mode.
e.g.
/direcory_name (insecure)

I have the same, problem..
and work with insecure option in export.
now, the problem is mounting resource with write access, because a can't write.
