I have a Redhat 9 NAS with an exported filesystem.

I have mounted this filesystem on to a HPUX 10.20 system.

Both systems use NIS for user authentication.

When I login to the Hpux system and cd to the mounted filesystem, I can
create a file or directory, delete it and change the group ownership,
but I a CHOWN does not work.  It tells me I am not the owner.

I have the system exported from the Linux system as

/exports/releases *(sync,insecure,rw,no_auth_nlm,no_root_squash)

Help would be greatly appreciated.

If you do an 'ls -l' on the file, does it show your user ID as owner?

Are you root when attempting chown ?
Can you create a file as root on the volume ?
(Your no_root_squash setting should allow this.)

Have you enabled chown for non-root users in /etc/privgrp ?

It appears the problem is with Redhat, chown is disabled for everyone
except root.  I will research at that end.

Thanks for everone's suggestions.
