Are there any thoughts about adding file transfer capabilities to PyDECnet at some point in the future? If a pyDECnet node could implement a FAL server to share a directory and/or offer a way to copy files to/from other nodes over DECnet, that would be really cool. I think it could make a very nice option for moving files between DECnet nodes and modern systems without needing to wrestle with Linux DECnet drivers or install TCP/IP on the DECnet nodes. I don't know how hard it would be to implement, or if there's any way I could contribute. I'm imagining a silly future in which there is a native Python implementation of an entire RSX-11 or VMS system. :) While I'm here... is this mailing list disappearing soon due to the Update eviction? I plan to chip in for an Update membership for 2022. -- Mark J. Blair, NF6X <nf6x at nf6x.net> https://www.nf6x.net/

DECnet/m+

by paulkoning＠comcast.net

I'm trying to build a DECnet/RSX system, and since I've never done anything like that I figured I'd try M+ as (right?) the easiest option. Did a sysgen, that seemed to work ok. Found a DECnet kit on Bitsavers, the 4.0 one marked "3errs", used that to do netgen. That too seemed ok. Now I'm trying "netins". That fails mid-way and I have no clue why: >@[5,1]netins >* Do you want to install and load the CEX system? [Y/N]: y >* Do you want to install and start DECnet?

SimH ethernet on Windows

by rien.timmer1947＠gmail.com

How do I setup the ethernet connection on Windows in order to enable SimH/VAXVMS to communicate with the world? I used: Set xu enable Set xu eth7 (my Wi-Fi connection) This gives me: sim> sho xu XU address=2013F948-2013F94F, vector=50, BR5, MAC=08:00:2B:00:01:05 type=DELUA, throttle=disabled attached to eth7 But VMS does not recognize UNA-0.

Disallow login on DZ line in VMS

Johnny Billquist <bqt at softjar.se> writes: >That /NOTYPE_AHEAD would disable logins in VMS is a bit surprising. >In my eyes, that's very unintuitive. /NOINTERACTIVE seems much more >sensible (yay for RSTS/E). When a terminal has no associated process and it receives unsolicited input, it forks into routine UNSOL in module TTYSUB. UNSOL notifies the job controller of the occurrance by sending a message to the job cntroller's permanet mailbox. This message contains the device name and precipitates the creation of a login process. There are various other actions based upon the type of terminal and other attributes of the device that may occur prior to the actions of the job controller but without TYPE_AHEAD, none of this occurs. >Sounds like VMS also have /NOINTERACTIVE...? VMS has no /NOINTERACTIVE. Interactive is a process right assigned to a process that is instantiated via an unsolicited interrupt on a terminal device. >In RSX, /NOTYPE_AHEAD just means you don't have any typeahead. If you >try typing something when nothing is reading, the characters are just >thrown away. But if a read is in progress, things works just as normal. I thought this was a question concerning VMS. -- VAXman- A Bored Certified VMS Kernel Mode Hacker VAXman(at)TMESIS(dot)ORG I speak to machines with the voice of humanity.

You'll also find that it will disable other terminal features you may desire keeping. >From the VMS HELP for SET TERMINAL/TYPE_AHEAD: SET TERMINAL /TYPE_AHEAD /TYPE_AHEAD (default) /NOTYPE_AHEAD Controls whether the terminal accepts unsolicited input to the limit of the type-ahead buffer. When you specify the /NOTYPE_AHEAD qualifier, the terminal accepts input only when a program or the system issues a read to the terminal, such as for user input at the DCL prompt ($). When you specify the /TYPE_AHEAD qualifier, the amount of data that can be accepted is governed by the size of the type-ahead buffer. That size is determined by system generation parameters. >Thank you for your explanation of how a login prompt gets triggered. >That was neat.

Disallow login on DZ line in VMS

by nf6x＠nf6x.net

The recent thread "Disallow system from dz lines (OpenVMS/VAX 7.3)" started me wondering how to entirely disable the login prompts on a given serial line, such as to use the port for some other purpose like controlling external hardware. I've been trying to find out how to do that in the manuals, but I haven't found it yet. It seems like it might be something to do with SET TERM, but I don't see obvious flags for that. Can anybody offer any hints? I won't be too surprised if my eyes have already glided over the answer in the manuals and HELP SET TERM text. -- Mark J.

DECnet/E programming manual / examples

by wboerhout＠gmail.com

Hi folks, I need to port a simple DECnet task-to-task program to RSTS/E V10.1, DECnet/E V4.1 Do any of you PDP-11 buffs have a DECnet/E programming manual. I know bitsavers doesn't. A small example in Fortran, Basic, Basic-Plus will also do. The functionality, expressed in VMS DCL, is as follows: $ open /read /write NETCHN REMOTE::"150=" $ write NETCHN "''f$trnlnm(SYS$NODE)'" $ read NETCHN time $ close NETCHN Thanks, Wilm

Disallow system from dz lines (OpenVMS/VAX 7.3)

by supratim＠riseup.net

OpenVMS VAX 7.3: This stops remote logins to SYSTEM even if correct password is provided (works for set host and telnet with Digital TCP/IP, though my version of MULTINET does not honor it). Is there a way to deny SYSTEM account access when correct password is provided from DZ lines? Network:? -----? No access? ------??????????? -----?

continued adventure with buggy DECnet on VAX/VMS 3.5

by supratim＠riseup.net

I turned the Ethernet circuit off and set up a DMC line to DECnet/Python. What seems to be interesting is the Area does not seem to be propagating as part of the DECnet address and confusing DECnet/Python. [Non-Issue, just saying.] The following four things are reported in a loop. Event type 4.11, Initialization failure, line fault#012? From node 31.32 (PIPY), occurred 17-Dec-2021 16:03:05.499#012?
