X, nfs/exportfs problems

[Roger Jagoda]

Folks,
 
Just a couple of questions:
 
The first is an X question, but although there is comp.sources.x
I don't know of a comp. group that discusses X so I couldn't
post it elsewhere (I know it's not a unixy question per se, sorry)
 
I KNOW this is a silly question, but I just can't find the answer. 
We need some sources for X11R3, note that R3 NOT R4. Gatekeeper at dec.com
and athena-dist.mit.edu both have just R4 sources. I'd like to go to
R4, but we've been given (curse of the university creed I guess) lots
of R3 server code free, we just need some additional things like client code,
man pages, etc. Does anyone know of a server that still has X11R3 for ftp?
Thanks in advance!
 
The second question deals with NFS/exportfs. We have a new Optical Drive
that we'd like to make available for nfs mounting to other workstations
on our net (we already mount everyone's /user directories so anyone
can use any workstation and get in to their home directory), but we're
running into "access denied problems."
 
In our /etc/exports table we have (for the BIG host, where the Optical
will be):
 
<stuff>
/ -rw,root=<the other BIG server in our net>
<stuff>
 
("<stuff>" is just comments and dates)
 
If I read the man pages right, this means export "/" on our server
machine to everyone read/write, and allow host access to the other
server. Great.
 
Now, on that same server, we mount th Optical drive with the mount
command:
 
mount -o rw /dev/od0a /OpticalDrive
 
Which means "mount this drive FS under ? as OpticalDrive"...right?
 
So all should be cool now, right? Wrong. When a local machine goes
to try to mount the Optical Drive directory tree with a command like:
 
mount -vt nfs <server machine>:/OpticalDrive /NetOD nfs rw,bg,intr,net 0 0 
 
is where we get the access denied problems. So back to the server, we
re-export everything (exportfs -va) and the server says "re-exporting /".
Fine, so back to the local hosts and we still get access denied.
 
If we mount the Optical Drive under / on the server and export /, can't
people nfs mount the Optical Drive on their local hosts? Does anyone see
anything obvious we missed here? Thanks in advance!
