A fix for this went into Linux 2.4.15 so if you're running a kernel older than
this I recommend you upgrade to 2.4.17 or 2.4.19pre8. (I can't honestly
recommend 2.4.18)

If you are using 2.4.15 or later then a dncopy -vvvvvvv and/or a tcpdup would
help in identifying th problem.

Hi,
I use dnprogs-2.17 on RedHat 7.2. When I try to copy a file from Linux to VMS,
dncopy waits for indefinite time without copying the file (copy from VMS to 
Linux works fine). Could anyone help on this?
Thanks,
Felix.

It's simply a matter of which systems I have acess to and how much time I have
to do it. I have no intention of discriminating agaist distributions but it's
quite a large job keeping up with just one or two these days so I tend to pick
Debian (cos I'm a Debian developer) and Red Hat because it's the most common -
remember, I do this in my spare time !

[Linux-decnet-user] Two questions no answers available

[Gregg C L. <dr...@wo...>]

Hello from Gregg C Levine
Question One: The X servers are either for Debian, or for Red Hat. Why
nothing for Slackware? As for why Debian, that I understand, one of the
folks here, states that he manages or maintains that set of packages.
Question Two: I have here, the software for the DOS implementation of
the whole DECnet system, this was originally written for the card that
plugged into the ISA bus computers that were prevalent at the time. And
someplace the software for the cards that were built by Racal under a
subsidy, this was for them to take the place of the original ones from
DEC. Has anyone here used that software? I haven't, I just collect it.
Missed the cards, though.

Same place as the other Phase IV specs,
http://gatekeeper.research.compaq.com/pub/DEC/DECnet/PhaseIV/.  At
least the V3.0.0 edition is there.  I think V4.0.0 was actually the
one that came as part of Phase V (not IV as in the title you quoted).
Even though it was planned to have the Phase V specs released, it
appears not to have happened and it's not clear whether copies of
those specs still exist.  For that matter, it's not clear if copies of
DECwrite, the tool used to create them, still exist.

In any case, there wasn't any significant protocol change in MOP
between the two specs.  The biggest delta I can think of is cleanup
around the retry algorithms for clients retrying the "load me"
message.

The specs for mop and many other DECnet protocols
are online at ftp://gatekeeper.dec.com/pub/DEC/DECnet/PhaseIV/index.html

The best place to get hold of old DEC equipment (I've found) is ebay or similar
online auction sites. Or generous donors if you're as lucky as I seem to be :=)

Hello from Gregg C Levine
Okay, Patrick, I agree with you, that something is broken on it
someplace. But my Linux box is only wearing one Ethernet card. So that
balances. My question was, and still is, "Do you have copies of those
documents, that you'd be willing to share? Or know someone who would?"
The other question is still that of hardware. Does anyone on this list,
have any useful contacts within the used equipment market, regarding the
units that are described both here, in this message, (look below), and
on the matching websites?

AIUI the mopd in Linux was originally written for NetBSD so they could boot the
VAX port. It was then ported to Linux by I know not whom. Incidentally there
seems to be a bug in that version that breaks mopd -a on machines with more than
one ethernet card.

The Linux/MIPS guys have done some nice mods to it so that it can boot ELF
images direct without having to preprocess them first (I forget the URL but I
can find it (or provide binaries) if anyone's interested.)

I use mopd to boot my DECserver 200 as well as my MIPS DECstation (for
some reason Linux 2.4 sets the frag bit on all UDP packets which it doesn't like
so I can't use bootp).

My LATD package has a moprc program (written from the specs you mention) which 
allows a Linux user to remotely manage terminal servers and trigger remote boots
of machines too.

[Linux-decnet-user] Specs for MOPD

[Gregg C L. <dr...@wo...>]

Hello from Gregg C Levine
Darndest thing. It turns out that Red Hat has a workable MOPD daemon.
Anyway, I have it installed on a 6.2 system running the 2.2.14 kernel. I
know its an older kernel, but that is what it came with, for
installation purposes. Are any of you aware of the availability of these
documents? "DECnet Digital Network Architecture Phase IV, Maintenance
Operations Functional Specification V3.0.0, AA-X436A-TK", and "DECnet
Digital Network Architecture Phase IV, Maintenance Operations Functional
Specification V4.0.0, EK-DNA11-FS-001". The man page for it, references
the manuals. My guess is that the daemon was written originally for the
Alpha port of Red hat Linux, and the author decided to bring it to the
I386 version. Still thinking about what kernel I should install on that
guy, and to track down the right hardware, but you know that one.
