FW: native Dup sync line revisited --> preliminary tests --> update logging Dup-Dmc communications

by R.Voorhorst＠swabhawat.com

L.S. Testing as it was done on the dup-dmc combination with the dmc side used as kind of proven reference. The initial section is a log (see pdf link: https://drive.google.com/file/d/1-m3h5fpvv3JHHUYWi3zgX_qtfm3g1aRs/view?usp=… as Hecnet seems to disallow pdf attachments) of a dmc-dmc connection that works out of the box and leads to a Decnet adjacency up message. Note that the dmc logging is not exactly time-sequential, therefor it is separated according to time stamp which reveals that xmt and rcv logging is not strictly ordered with respect to flow of time. This snippet shows the exact packets that are exchanged with their correct crc checksums. The dup-dmc logging in the second section below, can be arranged in lockstep with xmt/rcv and reveals an interesting anomaly where it seems somewhere in the beginning in dup two packets are coalesced, that at least is present in the dup logging, although the dmc does see it as two packets. >From there onwards, dup-dmc are getting in a loop. It looks like the dup logging itself is neither consistent or constant (some lines are sometimes present and later on missing). The coalescing probably indicates some error(s) in dup simulation leading to the dmc dancing around with the dup in bad crc error reporting, although the checksums of the packets look ok, until some form of reset takes place and then it starts all over again. Now it may be time to zoom in. Reindert

Connecting an HP Itanium BL860c to HECNET... without ethernet

by cyb2600＠gmail.com

Hello, A little while ago I purchased an HP BL860c server blade. It has an Itanium 2 CPU and I was able to install OpenVMS 8.4 on it. However I do NOT have a HP Bladesystem chassis to put the blade in, meaning I can only connect to it via the SUV console cable which provides usb, serial, and VGA. There's no way to get ethernet out of the thing without plugging it into a rather gigantic Bladesystem chassis that I don't have. If it was an x64 based blade running windows I could just use a USB->Ethernet adapter but of course those things don't have OpenVMS drivers. Given ethernet's not an option, would there be any way to tunnel DECNET over the serial port? It seems like that was possible on VAXen and maybe even Alphas but I've no mention of doing it on an Itanium. Or if anybody else has any ideas of how I could network this thing I would appreciate it.

That's part of the standard. VAX/VMS certainly did async DDCMP. I've no idea if that functionality got migrated to Alpha and Itanium. I'd suggest you try following the VMS example. If you can get the configuration steps to work (suggesting Itanium support) then this should work with a serial line going into a simh VAX. Good Luck, - Mark

Oldest VAX/VMS for VAX-11/730 on HECNET

But depending on application, it might be that all machines have to be up and running at the moment you're trying to use it, as opposed to UUCP which was store and forward. Where EVERY step of the uucp activity was store and forward, including the local (starting system). The uucp command just queued the file for local background/later copy to the next hop. - Mark

Updating Map Locations

by nf6x＠nf6x.net

A little while ago, I got a second hecnet link to let me get on hecnet from my office at my day job. I've moved some of my node names from my home in Riverside, CA to my office in Norco, CA. If I wanted to get a new pin at http://akdesign.dyndns.org:8080/map for my relocated nodes, do I need to pester somebody to manually update locations in a database? Or does the mapping crawler look for something on the nodes which might feed updated location information to it? I've begun putting .BEGIN-HECNET-INFO blocks in my INFO.TXT files, plagiarizing what I saw on Robert's nodes. But I get the impression that nothing automatically parses those at this time? It's kind of silly that my Riverside and Norco nodes are quite close to each other in southern California, but have two separate links up to the bay area. I can't accept incoming connections either at home or at work, so I have two separate links to Robert instead of just linking directly between my two sites. Sigh. I'm still happy that I can get on hecnet both from home and work, and my two sites can talk to each other. Interactive sessions are naturally sluggish when I do something like editing a file, but it seems to work quite well otherwise. -- Mark J. Blair, NF6X <nf6x at nf6x.net> https://www.nf6x.net/

machines up today

by mcguire＠neurotica.com

Hi folks, just FYI, some of you may notice LSSM machines (most of the machines in area 61) will be up and visible on HECnet through parts of today. Today is a volunteer work day at the museum, and a local company (Iron Mountain) is sending a group of volunteers to come and spend the day with us and help with various things. They'll be doing everything from cleaning to installing new surveillance cameras. We've been preparing for this for the past couple of weeks. Due to our perpetual short-handedness this is a really big deal for us. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Hecnet mail still alive? --> silence

by R.Voorhorst＠swabhawat.com

Ok, thanks. I asked because I saw no Hecnet internet mails since 1-dec-2021 and such a silence is (highly?) unusual . :) Reindert From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of R.

req for assistance: is snmp blocked for some / all ? does it work?

by supratim＠riseup.net

Hi, SNMP access to my Cisco works for me but does not seem to work for some others. I am wondering if it might be possible for others who have snmpwalk installed to issue the following and see if it returns the dnAreaTable part of the MIB. Thanks in advance. *snmpwalk -v2c -c foobar hecnet-us-east-gw.duckdns.org 1.3.6.1.4.1.9.3.1.26* Regards, Supratim* *

A USNO GPS network time server is now in operation at Digital Equipment Corporation, Palo Alto, CA

"A USNO GPS network time server is now in operation at Digital Equipment Corporation, Palo Alto, CA. This is an open-access stratum-1 for the Pacific Timezone: usno.pa-x.dec.com??? ?204.123.2.72 (CNAME ntp-dec.usno.navy.mil)" 204.123.2.72 still returns time as stratum 1. usno.pa-x.dec.com and ntp-dec.usno.navy.mil do not resolve.
