. is down temporarily. It is a simulation and I'm upgrading the Ubuntu host OS on that machine. With Linux, nothing actually works "out of the box" but most everything can be made to work with some effort. I'm still on that last step. I should have everything fixed up and LEGATO will be back today or tomorrow. Bob

Area 19 has returned

by steve＠davidson.net

HECnet area 19 has returned. It has only one node (SGC::) at the moment. DECnet is the only network stack functioning. Multinet is not yet available due to problems with SG1::. Johnny?s software bridge has been started so it should only be a matter of time before the rest of HECnet sees SGC::. An old set of sources to MWATCH (the system that controls address changes for Multinet) can be found in: SGC::[.MWATCH] It has some issues but works well enough if needed. -Steve Sent from my iPad

Thrashing about...

by Keith.Halewood＠pitbulluk.org

Hi, I suppose this happens a lot with newcomers to HECnet, especially when there are long periods of apparent silence. I'm currently reconciling remembering the '80s while listening to (having read several times) Ready Player One audio book (incidentally, I thought the recent film was... OK... but nothing like the book), playing around in VAX/VMS on a 86x0 SIMH simulator and doing 'real world' work in .NET (C#) for a salary, goggling in almost disbelief at the megabytes required to do what we used to be able to do in kilobytes. I have a vague recollection of TOPS-20 (possibly TOPS-10) so I built a SIMH environment. I have a vague recollection of RSTS/E so... etc.. I have no recollection of RSX-11M but I tried.... and yeah, etc... It seems it's VMS, VAX architecture (Alpha seems so new-fangled by comparison) for me. (I'm sooo glad Itanium is dying by the way - what an evolutionary dead-end - but what do I know - 'Itanic' seemed prophetic) Do any of you remember when UK Academia connected its universities together with X25 and 'coloured books' software? Yellow book was the transport, extending the addressing beyond the 12 digit DTE address, so you ended up with 000010500401.FTP.MAIL for example, to send Greybook mail via Bluebook FTP protocol. Redbook was to do with job transfer (remote batch job entry and processing, reporting). Pinkbook (I kid you not) was X25 over Ethernet.... And for a short while, I had set up X25 over Ethernet for DECnet between departmental microVAXen to the university's VAXcluster. Well, getting to the point, the 'coloured books' software on VMS was rather monolithic so I began the task of splitting it up. First, I wrote a device driver to create a pseudo-device to handle opening a Yellowbook connection. From then on, using the queue/batch system for processing FTP requests etc.. I can remember it all but it seems so pointless trying to recreate past 'glories'. When (in university days) you share a vaxcluster with at least 40 concurrents students EDTing then ALGOL68ing their programming assignments, it was fun to write a kind of 'TELL <userid> message' which mailbox'd a message to a central server which worked out if they were on the local node or somewhere else in the cluster, passed the message along and then broadcast it to the target user's logged in terminal. Incidentally, I'm missing Algol68RS for VAX/VMS - not part of the hobbyist programme possibly because it was never a DEC/Compaq/HP product).... Though why neither Bliss32 (in which I wrote the above device driver and support for Yellowbook) nor VaxLisp (don't ask why I would like this) are part of the hobbyist programme, I have no idea. So, what am I doing now? Apart from working in the real world, I'm resurrecting the Star Trek game I wrote in Ada ('83) using SMG$ routines - a more or less realtime version of the turns-based versions you see written in BASIC. Sad? Probably. I don't care. I'm reliving some of my happiest times. I may retreat to VAX Pascal if it proves too much. I'd still like VAX/VMS Algol68RS, VAXLisp and Bliss32.... because, well, just because. Sorry Keith

Hoping to join HECnet

by Keith.Halewood＠pitbulluk.org

Hi, I sent a message a while back to the 'responsible person' (as stated in the HECnet webpage) but have not received a response so I thought I'd try the list. Having recently rediscovered the delights of VMS(7.3 VAX architecture), the hobbyist programme and SIMH, etc. etc. I'd like to link into HECnet. Any help appreciated. I can do DDCMP-DMC (over UDP or TCP) or use the SIMH4.x built-in bridge. Regards, Keith

Automatic Orderly Shutdown of Emulated VAX/VMS System in SIMH

by supratim＠riseup.net

here's a quick hack. Run this detached from a privileged account, and telnet to port 1234 will cause an immediate halt. I actually did not run this from a system account; tested that I did get a %SYSTEM-F-NOPRIV from a regular account. Possibilities are endless; you might want to listen to private IPs only :) EXE is at QCOCAL::REMOTE-SHUTDOWN-LISTENER.ZIP or https://www.dropbox.com/s/kg1vs8zsf2jqn48/remote-shutdown-listener.zip?dl=0 :) On 6/10/2018 18:20, Supratim Sanyal wrote: > On 6/10/2018 16:00, Mark J.

Automatic Orderly Shutdown of Emulated VAX/VMS System in SIMH

by nf6x＠nf6x.net

I'm not sure if the HECnet list is the best place to ask this, but hopefully it's not too far off topic. Let's say that I want to run a full-time SIMH emulation of a VAX running VMS (because I do). This would be my full-time DECnet presence on my local network, my primary means of moving things between my DECnet-speaking computers and my modern machines, and my full-time HECnet presence if I ever find a good way to have persistent internet access at my rural home. The SIMH emulation would be hosted on a Linux server. It's easy enough to set up the host server to automatically launch a SIMH emulation at boot time, but I don't know yet how to deal with automatically and cleanly shutting down the emulation when the host server needs to shut down. In particular, I'd want to somehow trigger an orderly VMS shutdown when the host server needs to perform an unattended shutdown, such as when the UPS signals a power failure. If there's a way to checkpoint the entire emulation and then restore it later, that might also be a good option, as long as I can prevent corrupting the emulated system's filesystems by suddenly yanking the virtual power plug. Is there any prior art for setting up an unattended SIMH-based VAX/VMS emulation like this? -- Mark J. Blair <nf6x at nf6x.net> http://www.nf6x.net/

RVDSXL

by rok.vidmar＠gmail.com

Can somebory try to login via Hecnet to RVDSXL (3.47) please and report the result? There is no GUEST account on it, as far as I know. The machine is responding to ping, but telnet and SSH time out. -- Regards, Rok

help finding DECUS stuff

by mcguire＠neurotica.com

Hi folks. I've found something that I'm looking for listed in the SIGTAPES.SUM file in the rsx freeware CD v2, but I can't find the actual software anywhere. It's from the European 1984 RSX SIG Tape, Amsterdam. Maybe I'm being dense but I can't find that stuff anywhere. The specific software I'm looking for is called CCDRV; if you search for that in SIGTAPES.SUM it's listed there. Can anyone help? Thanks, -Dave -- Dave McGuire, AK4HZ New Kensington, PA
