I have been planning for a long time to post a small reflection when I
reached 1000 nodes registered in the hecnet nodename database.
This happened tonight. I think it is a pretty cool thing. There are now
1000 nodenames registered in this small hobby DECnet. I guess you could
say it's actually not that small.
However, I know that rather few machines are actually online, and it
might even be that the majority of nodes registered have never been
online. My guess is that maybe 5% of the registered machines are usually
online. But I do not have any hard data to back this up.
HECnet started out about 20 years ago from a desire I had to hook up a
PDP-11 I had at home, to some machines at my university, using DECnet.
At the time, I didn't have any TCP/IP for RSX, and the only way to get
any kind of networking was to try and come up with some way of getting
DECnet up.
My first implementation basically just forwarded a serial port
communication between two Unix machines. And on each end I then hooked
that serial port into a PDP-11 running RSX, and used DDCMP for the
actual DECnet link.
This worked, but was obviously not that fast, as the serial ports were
limited to 9600 bps.
After a year or so, I figured I could instead write a small program that
would forward ethernet packets. Using UDP I basically had the same
property as a local ethernet, but it could be located somewhere pretty
far away. From a DECnet point of view, it would appear as if they were
on the same ethernet segment, while in reality they were nowhere near.
As DECnet have pretty long timeouts on things, it turned out this worked
without a hitch, and I could achieve much better throughput.
Not long after that, the first other users were hooked up to HECnet as
well. This was maybe around 2003 or so.
Another data point is that there are 113 different persons that have one
or more nodenames registered.
Happy milestone, everyone, and thanks for being around.

Now that I'm done with Kermit-20, I wanted to get back to finishing up
some other work that I had been doing. FAL, DAP and NFT are in good
enough shape for me to leave them alone for the moment, so that's
another rabbit hole I've gotten myself out of.
I'm now looking fix an error that I somehow introduced into MMAILR (SMTP
over DECnet). Fixing this required modifying DDT, which I had to do to
fix another issue I had introduced into Kermit. I wanted to have a
quick look at what Tops-20 hosts might be up on HECnet and wrote up a
little batch job to use NETPTH to test connectivity.
NETPTH is a nifty utility to find paths between DECnet nodes. It builds
a connection the NCU's of various nodes to determine the path that a
message might take to get there. Think of it like traceroute or ping -R
(RECORD_ROUTE option).
It almost never works...
Before I roll up my sleeves and jump into this I was wondering if
anybody had any observations about the errors I'm seeing?

There is now an OpenVMS/x86 system on HECnet, as I would expect/hope, DECnet Phase IV seems to be working just fine. It’s routing through my VAX/VMS 5.5-2 system.

Version 5.3 is the first major release of Kermit-20 in two decades and
represents over a year of development for the following functionality:**
·Updates Kermit to version 7 of Tops-20.**
·Adds DECnet NRT transport to Tops-10, Tops-20 and Ultrix hosts.**
·Adds pseudo-terminal support.**
·Support for batch stream execution, including extensive testing.**
·Microsecond timing (limited by Tops-20)**
·Efficiency Enhancements**
·Symbolic (C) escape sequences and enhanced parsing**
·New and Enhanced commands**
·Revamped and enhanced macro facility**
I am still working out where this is going up on the Internet, but for
now, HECnet users can feel free to access the package anonymously as
follows:
VENTI2::K20: Kermit-20 Executable and release notes
VENTI2::K20D: Kermit documentation in various formats
VENTI2::K20S: Macro source code plus build files for Batch (.CTL)
and Interactive (.MIC)
VENTI2::K20T: Extensive testing control files and results
*Gigantic* thanks to Bob Armstrong for providing /countless/ Tops-10
cycles, support and other resources to me for testing and troubleshooting.
I'm celebrating climbing out of this particular rabbit hole by breaking
Tops-20 NFT, but FAL is OK. I think.
I wonder if anyone can help me remember/locate a language/compiler for
RSX that some third party did. It was allowed to be used on a hobbyist
basis in the early 2000s, if I remember right.
My brain says XDT or GCML as the company, but searching for that gave me
nothing. The language might have been something like RPG II, but again,
I am not at all sure my brain is remembering things right.
I thought I also had it downloaded and stashed away somewhere, but
cannot find anything now that I'm searching.
So now I'm hoping this things a bell for someone, somewhere, and I can
get my brain sorted, and another tool added on Mim (eventually). :-)

Hi All,
I've dusted off my PiDP11/70 running RSX-11M+ (v4.6). Anyway the "stock"
image that came from the PiDP site is not to my taste so I've been
trying to customise it. Nothing fancy just changing the system name from
the standard "PiDP11" to "WITHER". I should stress that I am an utter
noob and have zero experience with RSX-11 so doubtless I will use the
wrong terms and I know my issues are due to that lack of understanding.
To make my life easier with SYSGEN I was using the existing answer files
(SYSGENSA1.CMD, etc) and simply editing the items I want. The trouble
is, generating a system with these files is producing a system image
that has a very small secondary pool (SECPOL). That then produces
various errors with commands grumping that there is insufficient SECPOL....
I have figured out how to expand the secondary pool from the command
line (which prevents any grumping) but I would like to permanently fix
the situation. From the documentation that I've read, and as I
understand it, I should be able to pause the SYSGEN and edit files
manually mid-generation. In this case I should be able to edit the
"SYSVMR.CMD" which is generated at an earlier phase within SYSGEN and
then continue the SYSGEN which will then utilise the file (SYSVMR.CMD)
in one of the later phases . Except, it does not seem to work. Editing
the SYSVMR.CMD file prior to starting SYSGEN clearly overwrites the
changes during an early stage. Pausing the SYSGEN and editing the
SYSVMR.CMD file mid-generation does retain the settings but does not
appear to make any difference to the final image.
By way of a little more explanation. I'm presuming once I've "paused"
the SYSGEN all I need to do is EDT the SYSVMR.CMD file (in other words,
I'm not doing anything further, running any other commands or what-not).
All I'm doing is editing the SYSVMR.CMD file (specifically the "SET
/PAR=SECPOL" line), and restarting the SYSGEN with "UNS AT.<ESC>".
I presuming I am missing out either a vital step or command or
completely misunderstanding the "set /par=secpol" line.
Any pointers gratefully received

I got asked what the power requirements would have been for 1985 vintage
KL10 based system.
Does anybody know where I would be able to find such information? I had
thought it was in the site installation guide, but I haven't found an
online version, yet.
About the only thing I can remember is that it was three phase power and
that the power supplies were very inefficient.
I asked Bard to “Write a song about digital equipment corporation’s DECnet network”. The AI is surprising, the ending surreal.
(Verse 1)
Digital Equipment Corporation,
DECnet was your creation.
A suite of network protocols,
To connect your computers.
(Chorus)
DECnet, DECnet,
It was the best network around.
DECnet, DECnet,
It connected us all.
(Verse 2)
You could connect your PDP-11s,
To your VAX/VMS machines.
You could share files and printers,
And communicate with ease.
(Chorus)
DECnet, DECnet,
It was the best network around.
DECnet, DECnet,
It connected us all.
(Bridge)
But then the internet came along,
And DECnet fell out of favor.
But it will always be remembered,
As the network that connected us all.
(Chorus)
DECnet, DECnet,
It was the best network around.
DECnet, DECnet,
It connected us all.
