You know, I don't know whether the RPC specification clearly
indicates that procedure, 0, is the NULL procedure. It just
seems to be accepted practice and assumptions have been made
that procedure, 0, is the NULL procedure and also does not
require any special authentication.

The NULL_PROC is used as a "ping" sort of procedure by things
like rpcinfo, the NFS mount command, etc.
