Well, all the things which make the DECnet stuff painfully burdensome in a
simple environment like mine, turn around, I'm told, and make a more complex
and larger environment work better. Perhaps your system will benefit from
the presence of multiple protocols and layers. It doesn't look, from your
description, like a single segment. However, for my purposes, it's a single
segment if, without any intervening layers (other than the physical ones)
all stations can directly "see" one another, particularly, of course, the
collisions. Generally, people split up segments when the collision overhead
gets too large. It's hard to make that show up with half a dozen stations.
If you do as I did, by dumping vast quantities of highly dense data all at
once, you'll see the overhead rise.
When I got my 100 MHz stuff I was told by the tech support guy at Netgear,
an avid LINUX user, that I'd be best reducing the number of protocols
supported on my setup, so I deleted all references to Microsoft's NETBEUI.
I'm not sure it made things better or faster, but it hasn't hurt anything.
My setup is based on a NETWARE server, though, so I can't punt IPX/SPX and
the Windows boxes like to talk TCP/IP. Since I'm using that for WAN-ing, I
might as well make that the default. Now, if I could just find a TCP/IP
driver set for DOS that's not bigger than the NOVELL stuff . . .
Perhaps you could reduce the number of protocols a bit. It doesn't always
make a lot of difference, but you never know . . .

IIRC,
>Appletalk sends occasional traffic over an
otherwise idle LAN. I don't
know
whether it does
this when there really is traffic.
Yes, Appletalk does send a little over the network even when nothing is
going on, but not as bad as DECnet. Since I've got AppleTalk, DECnet,
Samba, and TCP/IP all running on the same network I've probably got a
pretty noisy.
Hmmm, just ran a 'tcpdump' and it looks like I'm taking a hit on the
network just by having a couple Appletalk shares mounted from the VMS box,
about 56-bytes minimum every couple seconds.
The numbers you quote seem a mite low, but not
embarassingly so. You are
configured as a single segment, are you not?
Not sure how you mean a single segment, there are two hub's attached to the
switch, as well as computers, plus I've got a 10Base2 converter and
localtalk converter (for the HP 5MP Laserjet) plugged into it.
Guess I'll have to turn on FTP on the DEC3000, and see what kind of speeds
I get that way. Besides I want to get FTP and NFS turned on anyway.

I wish! Let's see, if I want the Mac to talk to VMS I've got to use
AppleTalk, since DAVE (basically Samba for the Mac) and the Samba version
of VMS don't mix. If I want to talk to RSX-11M I've got to use DECnet.
Samba for Windows, since that's cheaper than getting NFS for Windows (why
pay for something I wouldn't really use). Then most systems talk TCP/IP.
In an ideal world every system would be running TCP/IP and using NFS to
access remote disks, but it's not an ideal world. Good luck finding NFS at
any price for the Mac (don't think you can get it for the Amiga anymore
either), and I've spent the entire evening trying to get the VMS box in
quesiton serving up NFS.

NFS clients for Win9x PC's at any sensible price (ie freeware or shareware)
seem to
be non-existent. I have Xlink on this machine, and it works well, but why
there
aren't a swag of free/shareware ones kicking around on the net is anyones

I don't recall seeing any free/shareware DOS/Win3x clients either.

I run Multinet 3.2 Rev B NFS Server on a 6000 under VMS 6.0 here,
and I have a VMS 6.2 Vaxstation that has UCX installed for tinkering.
What is the problem you are having getting the NFS server to work?

What is interesting on this note, is that there is a free client, and it
seems to work fairly well, for BeOS.

Hmmm, interesting.
I think the problem is with the way I've got the
Proxies set up. I can
mount the drive on my OpenBSD box, but can't access it, can't even see it
when I do a 'df' (that is a seriously wierd experience).
Sounds more like permissions may be involved. This is not as simple under
VMS as it is under Unix. (As you no doubt are aware)
I can't even mount it on my Linux box.
I'm wondering how it will react to one of the
Solaris boxes, but haven't booted one yet.
Good benchmark. If it mounts from that it's obviously a server problem.
I also can't figure out how to export a directory
instead of an entire
disk, it doesn't even look to be possible. I'd really like to export
DKA200:[PCTMP], instead of DKA200: since that's what's served up via
AppleTalk and Samba.
It's possible. Which IP stack/NFS Server are you using, & what version of
VMS?

You should be able to export a logical ("dka200_pctmp" = dka200:[pctmp])
and get your access control that way.

That was the way I expected it to work, but it didn't. I think the
following is the correct syntax:
TCPIP> map "/dka200" dka200:
TCPIP> add export "/dka200/pctmp"
I did some testing on the following proxy statement this morning, and it
seems that you need both this proxy, and the user proxy to get stuff to
work. The key thing is that the following doesn't appear to give everyone
SYSTEM privleges as I was afraid it might. Still makes me nervous, and I
still need to do some research on it.
TCPIP> add proxy /gid=-2 /uid=-2 /host=* system
