Folks - has anyone managed to get a GPS receiver that spits out NMEA protocol data over a USB port on a Linux box hosting a SIMH VAX to work as a OpenVMS stratum-1 NTP server using either digital TCP/IP services or Process MULTINET?

How frequently do you update your node list?

by tommytimesharing＠gmail.com

I finished my changes to FAL and DAPLIB to support ANONYMOUS usage on HECnet with some degree of security. Naturally, the first thing I did was regression testing, both with one of my 20's and another 20 on HECnet (TWENEX). Unfortunately, I couldn't do anything on TWENEX because it didn't know about my node definitions, so NFT had no syntactical way to specify the connection (that I could remember).? Intrigued, I went to a number of other 20's to see what a SYSTAT might show.? Aside from the fact that most of them appeared down, none of them knew about either TOMMYT:: or VENTI2::...? Well!! However, before I got too huffy, I wondered when the last time **I** updated was, the answer turning out to be "never"...? Shame on me.? So I knocked together a weekly batch job to pull a specially formatted node list from MIM::, suitable for swallowing by SETNOD (you have to have a RETURN statement at the end or you get an error which can blow up a batch job).? This also allows me to track (somewhat) the comings and goings of nodes which is of interest. So the question is, how frequently are the rest of you updating and how are you doing it?? My batch control file is below in case anyone with a 20 wants it. Meanwhile, I am looking for a few volunteers to contact me off-list to do a little alpha testing before I post the code for ANONYMOUS usage. ------------------------------------------------------------------------ @DayTime @Enable @Set Trap File @Define OLDS: PS:<OLD-SYSTEM> @Rename SYSTEM:NODE-DATA.TXT OLDS: @NFT *SET DEFAULTS MIM:: /USER: *SET DEFAULTS MIM:: /PASSWORD: *SET DEFAULTS MIM:: /ACCOUNT: *DIR MIM::FIX.T20;0 *COPY MIM::FIX.T20;0 SYSTEM:NODE-DATA.TXT *EXIT @Define OLD: OLDS:NODE-DATA.TXT.0 @Define NEW: SYSTEM:NODE-DATA.TXT.0 @Define DIF: OLDS:NODE-DATA.DIF.-1 @FILCOM *DIF:=OLD:,NEW: =^Z @SETNOD *TAKE SYSTEM:NODE-DATA.TXT.0 *SAVE *INSERT *EXIT @Information DECnet @VD OLD:,NEW: WEEKLY:: @CHKPNT WEEKLY @Submit GETNOD.CTL.0 - @ /After:+167:59:59 - @ /Assistance:Yes - @ /Batch-Log:Append - @ /LogDisposition:Keep - @ /LogName:GETNOD.LOG.0 - @ /Notify:No - @ /Output:NoLog - @ /Restartable:YES - @ /Time:00:01:00 - @ /Unique:No @Goto END %ERR:: @Original ERun NEW:MM.EXE.0 *DayTime *Send Nag *DECnet Node Update Error *Go figure out what went wrong and restart the batch job *^Z *User-Header Importance High *User-Header Priority Urgent *User-Header X-Priority 1 *Erase Bcc *Send *Quit END:: @Information (about) Batch-Requests @Echo That's all folks!

DAP

by tommytimesharing＠gmail.com

I have been fixing some issues with the file access listening (FAL) under Tops-20.? Briefly, it would crash on listing extremely large directories and return incorrect byte sizes and counts for files under certain circumstances.? It also did not support anonymous access as is currently used in HECnet (blank user name).? There were other issues. It's been a bit of a slog, the first two issues taking a considerable amount of time to solve.? However, they're fixed and I've got some prototype anonymous code running.? I would say that I am about 1 to 2 months away from an alpha test; the configurable restriction parsing is nearly done, hooks remain to be into DAP functions and deployment documentation to be written. Questions: 1. My own version of FAL appears quite dated; it only has edits to Tops-20 V6.1 (1985), whereas the last monitor distributions were in the 7 series. * Does anybody have any source files later than that for Tops-20? 2. What is the last version of DAP (any platform) for which a specification exists? 3. The implementing DAP module (DAPLIB) appears even older, apparently dating to V6.0, 1981 time-frame (which seems incorrect).? It? supports DAP 5.6, for which I have the specifications. * It does /not/ support $RENAME (ACCFUNC 3), which I found remarkable.? Is $RENAME supported on all other platforms? * I note that ACCFUNC 5 is reserved.? Is this used now? * Is ACCFUNC 0 used?? For what? * Is any ACCFUNC later than 8 defined?? What is the first free one? The reason I ask the last is that some of the logic is largely table driven, based on ACCFUNC.? This suggests modeling the restriction parsing and implementation in a similar way (I.E., off of ACCFUNC), which would be quite straightforward.? However, I want to be sure I understand those numbers. ??? ??? --T

Some SIMH weirdness on Raspbian

by Keith.Halewood＠pitbulluk.org

Hi, Perhaps this isn't strictly HECnet related but as HECnet traffic is traversing some part of this weird arrangement via pydecnet, I'm taking a chance: I run SIMH on Raspberry PIs under Raspbian Buster. I have both IPv4 and IPv6 networking switched on and a router/DHCP(v6)/DNS infrastructure to cope successfully with it. (Nothing is wireless for what I'm about to describe, not that it would make much difference) SIMH's simulated Ethernet devices on the PIs are TAP connections to a bridge device connection to a real eth0 - no problem here. SIMH instances' consoles and terminal MUX devices are listening on individual ports and I telnet into these usually from my PC via Putty. The DNS servers do not have AAAA for the PIs, just A, so the PC connects to the PIs via IPv4 - no problem here. The PIs show the SIMH instances listening on the right TCP ports but when I filter with -4, ie: netstat -a -4 I don't see SIMH listening. When I filter with -6, ie: netstat -a -6 I do see a listen on those ports. I notice that, for example, ssh listens on 0.0.0.0:ssh AND [::]:ssh but SIMH listens only on *:8601 (for example) The * seems to show up only when I restrict the search to the ipv6 family. The * seems to indicate a listen with no 'family' preference. An established connection to *:8601 seems even stranger. It only shows up when netstat is run with -6 but it shows the correct IPv4 addresses for each endpoint. It is an IPv4 connection anyway. The 'ss -6' command shows up something even weirder for the established (IPv4) connections: The local address port is: [::ffff:192.168.2.42]:8601 and the remote address port is: [::ffff:192.168.2.12]:61152 The IPv4 part of these ports is correct. Why are they 'encapsulated' in some IPv6 syntax and listed as IPv6 connections? Can anybody point me in the right direction for some explanation please? My google keyword searching skills seem a little off today. Regards, Keith

Re: [Simh] RQDX1 or RQDX2

Thanks. There gotta be something closer than AUS though... Although I have a friend that is about to relocate from Melbourne to Denmark in a few weeks time... :-) But nah. Definitely should be possible to find something closer. I know there is stuff in Sweden, if I just had the time...

Right. Good point. I hadn't even reflected on that early firmware versions for the RQDX1 can't handle the RD53.

Sorry, no. Maybe I should have mentioned that this is for a PDP-11 RSX version. I have most of the files, but are missing a few.

RQDX1 or RQDX2

by bqt＠softjar.se

Ok. So I had plans to locate an RQDX[12] during my christmas vacation. Unfortunately, events outside of my control have forced me to change my christmas plans, and I no longer will be able to get my hands on an RQDX[12] by my original plan. I have a bunch of RD53 disks that I want to dump out, and I need such a controller, so now I'm searching if there is anyone who could lend me one for a couple of weeks or so. I'm located in Switzerland, near Zurich. Anyone close by would obviously make it easy, but if anyone would be willing to ship from somewhere else, I'd be just as happy. I could pay for the shipping and return shipping, but can't really afford anything beyond that right now. I hope to locate a few missing files from a Modula-2 compiler among other things on those disks, and if found, it will be shared with anyone interested.
