I just bought a copy of FTP Softwares PC/TCP plus (includes PC NFS)
support. I'm trying to connect with an Ultrix machine and am having
problems. I tried calling FTP Software to find out what the problem was
and was told to contact my Vendor for support of PCNFS. FTP Software
provides a pcnfs daemon which apparently only works with Sun machines.
On the PC side it says it is mounting, asks me for a password and then
says that the Authentication daemon is not responding (or words to that
effect). The kind woman from FTP Software told me to get out a lan
tracer and watch packets go back and forth. If this was something like
NCSA Telnet plus with nfs support (doesn't exist), I'd get my netwatch
program out right away no questions. We payed for this though and if
worked we'd liked to buy more copies. The PC/TCP with out the plus seems
very solid. The manual for the nfs support is very lacking also.
Can anyone help me with a PCNFS daemon that works with Ultrix machines?
or do I send my copy of PC/TCP plus back for a refund?
thanks,
mark

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.
