Folks, I successfully installed DECnet/Python on Ubuntu 21.10 system and was successfully connected to HECnet. I have a few questions about DECnet/Python. I choose that because it support virtual circuits like Multinet over TCP, etc.. I can't find any apps (programs) to support DECnet/Python like login, set host, dir, etc. Only DECnet for Linux has programs. Does DECnet for Raspberry Pi work with Ubuntu 21.10 (Linux 5.13 for x86)?

DEC 4000/500 from years ago

by Mark＠Misty.com

Hi, Around 2007 I gave away my pair of 4000/500A systems, I believe to Brian Hechinger. They were taking up way too much space in the dining room, and that I just wasn't that interested in putting the time and money into sustaining the pair. I also really wanted SCSI storage, but Q-BUS SCSI controllers were way out of my financial reach at the time. Since then, circumstances have changed, and with renewed interest, I acquired a BA23 Q-BUS MicroVAX, and eventually a Q-BUS SCSI controller, but nothing that came close to those 4000/500As. Some years later, I believe Brian moved, and offered these up again on one of these lists, or maybe CCTALK, but I missed that posting until too late, and lost track of who ended up with those. If these are in use, I wish whoever has them the best, and am extremely glad at least they did not end up scrapped; I did my part towards that. However, if whoever has them is no longer using them, I am here and interested in whether one or both might be available. I hope this is an appropriate posting, and it is not misunderstood by those involved. Mark -- Mark G. Thomas <Mark at Misty.com>, KC3DRE

Apologies to those downstream of me on area 29

by Keith.Halewood＠pitbulluk.org

Hi, Apologies for my HECnet connections being up and down over the past day or two. I finally decided to 'upgrade' to a Draytek Vigor 2865ac router from the older 2862ac and/or the home grown linux/pf-sense I have been experimenting with on and off. Anyway, the documentation stated that I could dump the config of the old vigor and install it into the new one. It looked ok but quite frankly wasn't. Half the WAN side of things wouldn't come up and kept crashing the entire unit. So I configured it from scratch... and cleared out a load of old stuff as a result. Routing policy doesn't work properly and gets misconfigured when you're not using the default 'address of router' for NAT-based operations - support request logged. IPv6... yes I know you don't want to know or care... nevertheless... There's some (state sponsored?) port scanning on random IPv6 host addresses with my prefix. The router is naturally blocking them but the damned IPv6 neighbour table is filling up with them! They don't go anywhere, but over the last few hours, the table now has about 900 entries - another support request logged... and the bloody router hasn't been out of its box for more than a day!

Is MIM running?

. I can't seem to reach it. It's not a big problem, but I wondered if it was my issue or somebody else's. Bob

A2RTR downtime

by bob＠jfcl.com

A2RTR will be down tomorrow (Monday) for a couple of hours sometime between 9AM PDT and 3PM. It's not my doing - PG&E is replacing a transformer and the power will be off. I have battery backup for some of my equipment, but not A2RTR. Sorry. It's also going to have to go down sometime again, maybe next weekend, so I can replace a disk drive that's failing. I bought two identical drives and plan to set up a RAID 1 array this time. If anybody has set up a software RAID on Ubuntu, using the md driver and mdadm, for the system drive and you have advice, let me know. Espcially if you managed to make both of the drives bootable.

Some scanned documents for DEC

by mark＠wickensonline.co.uk

Just reviewing a retrochallenge entry when I came across some scanned DEC documents that may not be available anywhere else: https://jbretro.wordpress.com/the-latest-google-drive-link/ Regards, Mark. -- https://www.qrz.com/db/M0NOM/P

PDP-11 Unix V7M-11 V1.0 under SIMH

by tony.nicholson＠computer.org

Recently Al Kossow made available a zip file containing a Micro/PDP-11 installation kit for Unix V7M-11 V1.0 on bitsavers as RX50 disk images. Tinkering away here in Covid lockdown, I've managed to get this running under SIMH pdp11 emulating an almost historically accurate PDP-11/23 plus. I've placed the SIMH initialisation file, a couple of RD51 disk images and an "installation recipe" for making these disks on GitHub at - https://github.com/agn453/V7M-11 While I mainly had exposure to later versions of Unix and Ultrix-11 on a PDP-11/70 as an undergraduate - this one surely brings back memories!

Back on HECNET!

by mark＠wickensonline.co.uk

After a prolonged outage Area 4 is now back on hecnet via a new Raspberry Pi, so the archive on SLAVE:: is now available again (all the time the windows vm that it is being emulated on is up) as well as a debian VM hosted SIMH ORAC recreation. I'm planning on using a (real) VAXstation during this years October Retrochallenge (it starts tomorrow): https://www.retrochallenge.org/ Twitter: @retrochallenge After a shaky couple of retrochallenge I've decided to step in and help out with this one, but will also be hopefully using it as an excuse to spend a bit of time on DEC equipment. Also please note that it is DEC Legacy in Windermere, UK in two weekends: 9th/10th October. http://wickensonline.co.uk/declegacy/ Regards, Mark. -- https://www.qrz.com/db/M0NOM/P
