Over 50 replies over the course of a few hours. Thanks, thanks, and
thanks, very quick and very responsive.

The solution was for me to man share_nfs as opposed to share.

The syntax solution to /etc/dfs/dfstab was:
   share -F nfs -o rw,root=client-name /exported/file/system

Thanks again to the "way too many to list here",



My original post:

Searched archives on this a little bit to no avail.

This is a simple one.

I have an nfs server that shares a filesys over to another box.
When logged onto the nfs client as root I cannot change ownership of files
are over the nfs link, in other words, I can't change ownership of files that
physically reside on the server. I try to do a chown and get the "Not owner"
error. I have taken for granted that you just cannot do this over nfs.
Sure I can copy files over and write files to the dir and even rm and chmod
Just cannot chown them.

Doing a man of share didn't tell me a whole lot.

I have openned up perms to 775 on all parent dirs and files involved to
include the mount points.

Do I need to set perms to 4755 or something like that? Or is this a simple
security feature that I simply cannot get around.
