To specify the UID and GID for remote root users, edit the '/etc/exports' file and add the following for each export: anonuid='value greater than UID_MAX from /etc/login.defs' anongid='value greater than GID_MAX from /etc/login.defs' Alternatively, functionally equivalent values of 60001, 65534, 65535 may be used.


Parameter:

[max_uid_gid]


Technical Mechanism:

Specifying the anonymous UID and GID ensures that the remote root user is mapped to a local account which has no permissions on the system.
