Happy 2021 to everyone in HECnet land. I hope that it is an eventful and fruitful year for all and that it isn?t as bad as the year we are leaving behind. Cheers, Wiz!! Sent from my iPhone

PyDECnet and IPv6

by paulkoning＠comcast.net

Why? Because I felt like it and it wasn't too hard. I have a PyDECnet version that can handle not just IPv4 but also IPv6. It's on node PYTHON right now and on the map server 28NH (at akdesign.dyndns.org). This applies both to the web interface and also to the various IP-based datalink protocols. I've tested Multinet, GRE, Ethernet (UDP bridge) and DDCMP. If anyone is interested in using this with PYTHON, let me know. Unfortunately dyndns.org doesn't support IPv6 records well; I can enter one manually but it disappears after a while for reasons I do not understand. It's there now. You can access the mapper's web page (akdesign.dyndns.org:8080) that way if you like. paul

Generating a note list for pyDECnet

by bob＠jfcl.com

I'm embarrassed that I don't remember this, but somebody had a way to generate a HECnet node name and address list in a format compatible with pyDECnet. How did that work again? Thanks, Bob

PCVMS

by supratim＠riseup.net

Hi It appears once upon a time there was some sort of a VMS-like shell on DOS called PCVMS from Wendin Software. Sampsa asked for it from the last person to work on it 11 years ago at http://personallyinteresting.blogspot.com/2009/04/computer-archeology.html Wondering if Sampsa or anyone has floppy images. Thanks. -- Supratim Sanyal, W1XMT 39.19151 N, 77.23432 W QCOCAL::SANYAL via HECnet

VMS Cluster Group Number Coordination

by nf6x＠nf6x.net

Do VMS cluster group numbers need to be coordinated on HECnet? If so, is anybody taking care of the coordination yet? I'm getting ready to set up a VAX cluster in my little patch of area 2. -- Mark J. Blair, NF6X <nf6x at nf6x.net> https://www.nf6x.net/

DECnet for Linux Bug Fixes

by john＠forecast.name

Recently I have found, and fixed, a number of bugs in the DECnet for Linux kernel module. Some of these bugs may be relevant for members of this mailing list who are using DECnet for Linux, especially on a Raspberry Pi. Major bugs fixed: - Ethernet Listen Timer was not implemented In addition, the check for an address change for the designated router (DR) was missing although there was a check if the DR?s priority had changed. Note: this code changes the format of /proc/net/decnet_dev to include the listen timer value. nml/nml2 needs to be rebuilt to understand the changed format. - System panic when using the loopback device (lo) The DECnet code was missing a destructor routine which is used to avoid data copying. - The neighbour (adjacent node) code could be broken by kernel changes The code made use of a now deprecated feature (zero length array at the end of a structure) in order to access data in a surrounding structure. This happened to work ?by chance? until kernel 5.4.42 on 32-bit processors. - Interrupt message flow control was broken The flow control was a mixture of using the SEND/DONTSEND status of the data subchannel and a message count. This seems to work between Linux systems but is broken when communicating with other systems - during the life of a logical link, the remote system could only send a single interrupt message while the Linux system could pretty much send as many interrupts as it wanted possibly overrunning the remote systems buffers. - Optional data on received connect confirm message was corrupted The code was getting the optional data from the wrong offset in the message. - Next hop cache problem 30 seconds after a logical link was taken down, the next hop cache entry was deleted. As part of this deletion, the link was taken ?down? which caused a neighbour entry to be created for the same node address but accessed via the loopback device. Sometimes this would cause the designated router to become accessible via the loopback device and subsequent connections would fail. - Intra-ethernet bit ignored The intra-ethernet bit in the routing flags is ignored on inbound traffic. If there was a neighbour entry for the remote node at connection time, everything would work correctly. If there wad no entry, all outbound traffic would be sent through the designated router for the duration of the logical link. - Promiscuous mode alters DECnet behaviour If the ethernet NIC used for DECnet had promiscuous mode enabled (e.g. using tcpdump for traffic tracing), the DECnet code would start seeing endnode hello?s, populating neighbour structures and causing the problems described above for the intra-ethernet bit to go away. New programs: DECnet Test Send and DECnet Test Receiver (DTS/DTR) Test programs created via reverse engineering the protocol exchanges. Used to find a number of the bugs described above. NML2 New implementation of the Network Management Listener. Supports SUMMARY, STATUS and CHARACTERISTICS for NODES, CIRCUITS and AREAS. It does not support LINKS and OBJECTS which were in the old version but are system specific operations which were only visible from DECnet-VMS systems. The old version is still the default during installation. The new version can be installed by: cd dnprogs/nml2 make sudo make install which will overwrite the installed executable and man page. OS Support: As of 06/29/2020 the code has been tested with: Raspbian 2020-05-27 release with kernels 4.19.126 and 5.4.44 (32-bit only) Pi OS 2020-05-27 32-bit release with kernel 4.19.126 and 5.4.44 pI OS 2020-05-27 (fully updated on 06/26/2020) with kernel 5.4.49 The source code and installation instructions are available at: <https://github.com/JohnForecast/RaspbianDECnet <https://github.com/JohnForecast/RaspbianDECnet>> John.

Guest access to a VMS IA64 server on HECnet?

by Keith.Halewood＠pitbulluk.org

Hi, Are there any owners of IA64-based VMS servers on HECnet with either some sort of guest access, or willing to give/loan me a guest account so that I can compile a pascal program or two? I'm interested in the sort of code produced (PASCAL/LIST/MACHINE_CODE) and also more generally interested in the 'feel' of VMS running on such a beast anyway. I go to say or type O___VMS but it seems that only the VMS bit makes it out. Regards Keith

Announcing RPM, a software packet manager for RSX-11M-PLUS

by bqt＠softjar.se

There is SLIP... ;-) I have never tried the SLIP code, but I did write it. It could be an interesting test... (I also have the skeleton of PPP, but I have not completed that one...) But anything on a beaglebone or whatever will not really help. You need some kind of interface on the PDP-11 side either way. Ethernet is the obvious first choice, but serial lines is (I guess) the next best thing. Serial DECnet or serial IP don't make much difference, except I think you'd find serial IP more useful in the long run. Once you have even that, you could run DECnet over IP if you wanted to join in a DECnet sense.
