Restrict NFS access to root
Hi Everybody,

If there is a general NFS share in the LAN and for example this share has three files - a, b, c is there any way to restrict file access to the root user of one particular host(falcon) in the same LAN environment while the normal users from the same host(falcon) should be able to access the NFS share & files a, b, c.

Thanks in advance

May be give a try with this..

Code:
/mount/point    falcon(root_squash)  *(rw, no_root_sqaush)

However this will not prevent reading...you need to take care of that using file permissions..

What's to stop the root user on the "falcon" server from running "su - useername" and getting access to the files that way?
