RPC/XDR is a necessary component of NFS, but it is not a "part" of
NFS any more than IP is.  We demonstrated NFS over OSI connectionless
transports more than 2 years ago, for instance.

RPCSRC 3.9 (I assume that this was what you meant by RPC 3.9) is a
reference implementation of the RPC/XDR libraries.  The reference base
is BSD, not System V.  It is a "freely licensed" piece of code.

You shouldn't expect it to run on top of Interactive's IP stack unless
the socket interface that you got from Interactive is the same as
Berkeley's 4.3.  Headers may be only part of the problem.  RPCSRC 3.9
is not what ships with any particular vendors implementation of NFS.
RPC does, but not RPCSRC (which is a particular instantiation of RPC).
The interface to the RPC libraries should be the same across all
implementations (I would like to hear, if this is not true).

It sounds like you did not get the RPC from Interactive.  Why not?
Don't they supply it external to NFS?

You are welcome to share any changes that you make to RPCSRC for
creating a reference version for Interactive's socket interface.
Just leave the copyright notices intact, so that others are also
allowed "freely licensed" access to the code you send out.  

By the way, there is a RPCSRC 4.0 available in the sun-spots newsgroup
at Rice University.  It was supposed to have made it into comp.sources
last March, but I am not sure if it has actually gotten out yet.  This
release contains Secure RPC, which has an improved authentication
mechanism.  It also assumes a 4.3BSD base.

	RPC is a standard part of NFS, no? I recall (faintly) somewhere that
Interactive advertised this as part of their NFS product.

	I have a copy of their Host-based TCP-IP, and the RPC3.9 source code.
My experience is that with modification of the headers, I could get it to
compile, but it would crap-out at run-time. This was a few months ago, so I
don't recall the exact error. I will be trying again soon, however.
