NFS implementation details

[Peter Clitherow <pc%ctt.ctt.bellcore.com@RELAY.CS.NET>]

Is there someone with knowledge about NFS protocols?  (Anyone from ILA
read this list?)  I had originally directed the question below to the
comp.unix.wizards and comp.sys.sun newsgroups, but having less than
complete response there, i thought i'd try this avenue.

Presumably, the NFS code ILA wrote interfaces to ypservers in some
fashion, so someone up there must know the details of the protocols...

Ideas?

I have a need to develop a yppasswd interface for a non-SUN machine
(specifically, a LISP Machine), and not being a Unix or SUN wizard,
cannot find where the details of the yppasswd protocol is documented.
Can some kind soul enlighten me?  I believe, that if i ask on TCP/UDP
socket 111 (port mapper) for the socket that yppasswd uses, then i can
use this to authenticate a login from a yp server of some kind.

Or is there an easier way to do all this?
