   I need info. about NFS for Apollo machines.   Where can I get the

From you friendly local HPollo dealer, where else?

   and is there any problem in installing in Apollo DN3500.

I would not think so.  You might have difficulties using it, though.
I seem to remember some discussions in this forum about various NFS
bugs a while back, but didn't follow those threads at the time.  Now I
have a question/problem of my own.

Short summary: Problem with a mounted foreign file system.  From the
mounting node, only root has access privileges.  From other nodes, all
users do, except fror one node where the mount directory does not even
look like a directory.

Read on...

I have mounted a tree from a Sun on one of our Apollos.  In the Sun's
/etc/exports file, one line reads

/local/ftp	-ro

So I mounted it read only on one of our Apollos:

# /etc/mount -o soft,ro -v ugle:/local/ftp /global/ugle

and as long as I am root on the node that did the mount, OR I am on a
different node, I can cd /global/ugle (or cd //hufsa/global/ugle) and
see the files there just fine (but kind of slow, I think).  However,
as an ordinary user on the node that did the mount:

hufsa 136 % ls /global/ugle
insufficient rights (process manager/mapped segment manager)
hufsa 137 % file !$
file /global/ugle
insufficient rights (process manager/mapped segment manager)

Also, on one particular node I get:

tootikki 36 % file //hufsa/global/ugle
//hufsa/global/ugle:   nfs_gate

The correct answer is "directory".  But from this node the file looks
like an ordinary file, although of an unusual type.

tootikki 38 % cd //hufsa/global/ugle
//hufsa/global/ugle: Not a directory

WHat's going on?  Any ideas?  (Did I not RTFM well enough?  I tried!)
