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

Announcing TCP/IP for RSX-11M-PLUS

by bqt＠softjar.se

Time for a new release announcement of TCP/IP for RSX-11M-PLUS. I usually try to avoid spamming lists with release announcements, and the previous announcement was only a month ago, so I apologize in advance for the noise. However, I have a really good reason for this announcement. In the last few days I identified a bug within RSX, that has been latent for many years, but which gets activated when TCP/IP is installed. Because of this, I've cut a new distribution of BQTCP, which now also includes some patches to RSX, which I really implore everyone to install. Highlights: - Stability and reliability improvements in RSX. - Improved stability of Multinet. - Improved stability of MAILD. Detailed information on things that have been done since the last release: RSX: - The MCR REMOVE command have an interaction with the IP: device driver, which have a bug. Traditionally, the IP: device driver was for the IP11 device, which I doubt anyone have used in many years, so this bug have probably been around a long time without detection. The result of it is that low core and pool will get corrupted when giving the REMOVE command, and IP: exists. BQTCP now includes an optional "patch RSX" section in IPGEN, which will install a new version of MCR on the system. This is only needed to be run once, as the patching is installing new tasks, and changing the bootable image to use these new tasks, which is a more permanent change. Along with the fix for the memory corruption issues, the new version of MCR will also fix a few other issues that people might or might not have noticed. There is some more details in the BQTCP documentation. Multinet: - Some transmit errors should restart the link, but this was not done. Fixed now. MAILD: - Added paging to mail reader. - Improved remote node system type detection for DECnet. - Improved the memory layout of MAILD, to avoid some crash situation. As usual, the distribution is available from: ftp://mim.update.uu.se/bqtcp.dsk ftp://mim.update.uu.se/bqtcp.tap ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk The documentation is also available through ftp on Mim, or also at http://mim.update.uu.se/tcpipdoc The firewall for Mim have now been removed, so no need for the alternate ports, but Mim is still listening to the alternate ports as well. ftp: 10021 telnet: 10023 Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.

Multinet IPv6 DNS lookup Induced Delay

by dwe-6006＠philtest.org

I have seen this elsewhere but I see no reference to a fix to the problem on Multinet. I have a Multinet SSHD agent running and when I attempt to do a connection the connection does succeed but it can take 90 seconds. I put a Sniffer on the line and the SSHD agent is attempting to do reverse DNS lookup on the incoming address. This is normal, but it is doing 6 IPv6 resolution attempts (3 to each of the 2 DNS servers) before it makes the first IPv4 request. I do not have IPv6 configured on the interface (or any interface) and I need to find a way to suppress all IPv6 DNS queries( PTR or AAAA) is here a magic incantation or a logical name that makes this happen?

Connections?

by bqt＠softjar.se

Guys. I figure I should try to get a more formalized handling of connections to HECnet. With my bridge, it's mostly just people connecting to me, but this is not a solution that scales very well, so in general I now try to discourage people from this option. When possible, I prefer to move people away from it. Multinet on the other hand scales well. And is possible to use directly both in VMS and RSX. However, it is silly and inefficient if all multinet links are to go to me. So I'm thinking about identifying a few people/places elsewhere in the world, which can be used for connections where it makes more sense for a somewhat closer point of connection. So, I would go on dealing with Europe. Might at some point be that we'd like a second point in the south of Europe, but that is not a high priority right now. However, for the US, it would be nice if we could identify a location on each coast, which have a capable system, and normally is always online, and which have a good bandwidth, and would be willing to setup connections to new machines that want to come online. So, are there any takers? I'll continue to be the first point of contact when people come asking, but I'd be happy if I could redirect them to the appropriate person once we have figured out a few basic details. And then these two persons can work on establishing the actual link.
