[HECnet] Is this the most up to date version of DECnet OS numbers?

[Keith Halewood]

Most of today’s experimentation is due to the mention of linux around DECnet and LAT… It’ll give the VT510 I have a little bit of freedom with a serial console to a tiny little Pi and then on, via DECnet or LAT to the rest of the kit, simulated and real. Now all I have to do is stop pronouncing ‘llogin’ (set host/lat) in the Welsh fashion, ll being a voiceless L sound.

Tony – it’s all there in John’s git repo, see below:

I've been running latd on my Raspberry Pi 4 for a while (the default install starts up using the hostname as a service name).
From OpenVMS LATCP it shows up as -

LATCP> show service pi5
 LAT Control Program
Service Name:     PI5
Service Status:   Available
Service Ident:    Linux 5.10.63-v7l+

Node Name            Status      Rating   Identification
PI5                  Reachable     10     Linux 5.10.63-v7l+

Would you care to share your RaspbianDECnet mods Keith?  I'd like to try this too.

The other question to me is - should I pioneer this using the just released Raspberry Pi OS Debian Bullseye?  I think I might!

Well, that was an interesting compilation of the raspbian kernel.
I cloned https://github.com/JohnForecast/RaspbianDECnet and got busy. I had to remove the --help-- stanzas from the Kconfig file. They were tripping something up.
I had to move the MAC address change to the bridge (I use /etc/network/interfaces with bridges and taps etc..)

DECnet is all working on a 32bit raspbian on a pi3b+, HECnet node name 29.115 - I'll christen it at some point :)
Thank you John Forecast for doing all the hard work.

Right. It was/is slightly more than a toolkit. It does have a couple of processes which deals with circuits and executor management. And I think there is TLK/LSN so you can communicate. But beyond that, you were on your own.

And no, OS/8 under RTS-8 don't allow them to be counted as one. :-)

Linux was definitely defined post-DEC. I simply just talked with a Linux FAL from RSX and checked what value it put in the OS field, and added that to my list from there.

I don't think it's the same as the RSX20F frontend. I have no idea what it is, but it's in the source files for the RSX DECnet code. Sounds like some oddball thing that existed somewhere. CSS thing maybe?

I almost suspect it might be, but again, no real clue. All I can say is that this is what is in the RSX sources.
