From: <Paul_Koning at Dell.com> Can't search microfiche, and a fiche reader is a clumsy and hard to use contraption. I always figured that was the whole point. You had to do a *lot* of squinting and typing before you could do anything that DEC didn't want you to. John Wilson D Bit

Peter, Everything is now set up on my end. I now have 3 Cisco tunnels. The metric is 10 on all of them.

VMS sources (was: Re: [HECnet] NCP-F-NETIO)

by Paul_Koning＠Dell.com

Listing or sources you can obtain for a fee are not open source. What DEC and others did is to provide listings you could read, but you weren't allowed to use or modify the code. Sources, maybe, but even then I don't think you could hand the resulting executable bits to anyone outside your organization. On the other hand, there are some interesting cases of code accidentally landing in the public domain, due to having been let out of the building without a copyright notice in place. Until 1976, that would make it public domain. I don't think that happened with any DEC software -- I remember being at the receiving end of some very stern lectures about copyright notices. But it did happen to CDC (in the early mainframe operating system COS) and to IBM (with OS/360). paul On Jan 8, 2013, at 3:08 PM, Clem Cole wrote: You have to understand, the concept of "Open Source" is not new. Most vendors supplied the source listing, and sometime even the code. There was a fee to copy it all (it was said in the old day it was impossible to write a mag tape anywhere for less than $100). So the fees we really set high enough to keep the idiots away, but low enough that the customers that needed them could get them. Remember a lot of it was in assembler, so it did you little good unless you had the vendors HW. A few things changed that all. First, the practice became less prevalent by the later 1970s primarily because of the Amadhl Corp making and selling a 360/370 clone. Interestingly enough, DEC did not sue CalData because of the SW. It was because they cloned the Unibus AND used the PDP-11 instruction set. Second once writing more and more of the OS in a High Level Language became de rigor, the ability to "steal" SW IP seemed to be more of an issue (although DEC was in good shape because no one but DEC would use BLISS). So around the late 1970s, DEC and most other vendors began to be more protective.

Fair enough, I'll run my Beirut network in area 8.. sampsa On 8 Jan 2013, at 16:24, Johnny Billquist <bqt at softjar.se> wrote: I'm probably going to come back and make more comments on this later... However, a couple of points and responses right now... Eve today, areas do not correspond to adminstrative control that much. There are areas which have several different people responsible for different machines, and atleast I have "sub-delegated" parts of area 1 from time to time. Yes, we will be running out of areas eventually. Based on the current growth, I'd guess a couple of years at most, and then we're out. Areas should be used for administrative reasons, and relate less to any geographical constraints. DECnet areas work perfectly fine spanning large distances. "Sub-letting" areas should definitely be a valid approach. Each user in one area can still have their own area router, and their own connections to the rest of HECnet, as long as they also have interconnects within the area. Data mining is difficult, since there are different systems, with different possibilities of extracting it, and in different formats. A centralized repository of data is nice in many ways, but it is a headache to manage. That said, I could be convinced of setting something semi-automatic up. A reasonable way would be for people to give me machines to poll, and then I'd setup an automated process to poll those machines for files in a specific format. I can then create a database out of that, and make it available through the web, as well as over DECnet, and also as a summarized file. Anything would be pretty easy if we just have the data collected. I already have something of a start for this in the form of my database of nodes in HECnet. I'd need to extend it with more fields, but that would be pretty easy. It's all in Datatrieve today, and that should be accessible over DECnet right now (even though I seem to remember that VMS hosts had some problems with that). I'm already extracting information from that database for the hecnet web-page on MIM (accessible as Madame). So, if we can just decide on what we want, and how to make the information available, I'll sit down and write the code to fix it.

We really need to find a way around this issue that doesn't involve manual maintenance of routing info. Perhaps an agreed-upon entry in INFO.TXT ? That's still manually managed, but it's managed by the individual link owners. Well Brian raised the good point of "on which host?" ...I think the problem here is that INFO.TXT really looks like, to me as a relative HECnet n00b, a per-"domain" file...but there's no clear delineation of administrative domains here. We've been using areas, but we're running out of those, and there's no consistency in the node numbering within each area. We could all agree to have "an info node" with a particular node number within each area, but that won't work when we start having multiple administrative domains within a single area. Johnny talked about exactly this just today, in the context of Sampsa's relocation. Dividing lines between regions of administrative control will not correspond to area numbers for much longer, its sounds like. Yeah, I've been noticing that...I've up-to-now used a specific "info node" approach...but it DOES get a bit wonky when I divide my stuff, or skip a node number or re-use a node number. (On a semi-related note...I might implement personal node-number schemes: separating PDP-11 sims from DEC-20 sims from VMS sims from physical hardware and so on.) Perhaps a centralized database that maintains per-NODE info, not per-AREA info. Then that database could have a field that denotes the point of administrative control that is responsible for each node. Centralising the NODE info could solve a lot of problems and make data mining easier. ;) I'd also like basic (Geographic location(s) (see below for further comments), owner, that kind of stuff) per-area info to be defined in this central database. (To be honest, I'd then break it down in to sub, and sub sub areas but at times I can go a bit overboard with creating subcategories...I doubt anyone other than myself would like breaking down their areas /that/ much.) Then, some mechanism (either automated, manual, whatever) would then populate that database. Perhaps there could be several population mechanisms...a program that runs under VMS, RSX, RSTS/E, or whatever, and something over IP for everything else. A web interface to the database would also be nice. How would it be done? Flatfile and having Johnny or someone add all node info by hand? ;) -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Se my previous post, do the same thing, IP address on your side? My end is set up! The address is 50.73.179.1.
