root_squash - Requests from root clients are mapped to the nobody user and group ID so they will only have file privileges associated with other.

Post Simple Logic for root_squash

Hi Suresh,

The normal behaviour of a user is that he can access his files on the NFS Server just as he would
access on a normal filesystem (ie local server & not NFS Server)

So it is not desirable that the root user on a client machine is also treated as root when
accessing files which are mounted by the NFS Server.

Hence uid 0 is normally mapped to a different ID ie nobody uid. This mode of operation is called
as root squashing

help, plz
