As presently widely implemented, NFS depends entirely on the client's
assertion that the user is who he claims to be (as implied by the Unix
uid/gid the client sends).  PCs have no such security, so Sun
developed a separate protocol (implemented in 'pcnfsd') to require the
user to supply a userid/password before being granted access.  Sun
wrote the program, and supplies source to those who want to use or
redistribute it.  They also maintain a collection of versions ported
to other operating systems.

PC/TCP Plus (and Interdrive) are distributed with the Sun 'pcnfsd' in
source form (I believe that Sun's own PC-NFS comes with the same
source, and perhaps Sun 68020 and Sparc executables, and I don't
know which way Beame & Whiteside chose to do it).  You don't say what
version of Ultrix you have, but the source we supply just built (no
editing) on our Ultrix 2.0 and 3.0 systems.  You do need to find the
right libraries (it uses RPC), and you probably need to be root to
add it to /etc/rc.local so it will be started on every boot.

Installation directions are in the "InterDrive User's Guide", section
1.4 ("Installing and Configuring the PCNFSD Server"), and the fact
that 'pcnfsd' is required is mentioned in the IDMNT manual page, and
in the "Troubleshooting" section.
