Hi all!!! While educating people some unix stuff (at time, spare from work as admin), I have a need for making some simple UNIX-like environment for people to try to type some simple commands. Now I need to make it possible to do it remotely. Are there any emulators, that are capable to run V5/6/7 or (better) 4.2BSD, and accessible by telnet or something like that? Additional thing I need is vi, any emulator that is capable of running vi could make me happy!!! Emulation is needed because of unlimited virtualization possibility, unlimited variation of configurations, and, of course, zero time for recover after root errors. simh runs fast 60 instances on P233. But now I need vi :( Thanks a lot! S.

This is what I get along with the permissions moan. But curiously if I run it sh filename then all works. It is as though there is some global shell permissions set up that is munged.

What happens is that sometimes I get a permissions complaint but sometimes I get a "bad interpreter" message. If I execute the shell with the file name as a parameter then it all works. I'm stumped.

simh+Quasijarus success

by Sergey Lapin

Hi, all!!! Still trying to implement multi-user unix-learning environment. So, I run simh with Quasijarus, when I telnet to port, that is redirected from serial, it automatically picks up unused line, that is fine, and eleminates a need for reconfiguration. But there is something interesting: I want to implement possibility to allow outgoing connections from emulated VAX. As I understand, 4.3BSD supports SLIP protocol. And I can get SLIP working through emulated serial line. So, the problem is: 1. How it was used to setup SLIP lines in 4.3BSD? :) 2. The other end - will slirp package work in such case? All the best, and thanks for all help, S.

Lions' V6 source code

by Maciek Bieszczad

Hi, What version, exactly, of 6th Edition source code is contained in the Lions' commentary booklets? I took a look at the version available for download at [http://v6.cuzuco.com/v6.pdf] but it does not seem to match the source code in the TUHS archives. If the source code was in fact modified by Lions, are there any machine-readable versions available? Regards, Maciek.

Re: [TUHS] Lions' V6 source code

by Brian S Walden

This is good. You can also get the straight text of the source without the line numbers by just removing the .html suffix of the the file (e.g try http://www.tom-yam.or.jp/2238/src/lp.c) I cannot read Japanese so I don't know if it says how it was produced or it's origin. But I can tell that it is not a derivative of the PDF I produced. -B > Well, I found a Japanese page that seems to have the Lions-formatted V6 code available in HTML format, just in case anyone is interested: > > http://www.tom-yam.or.jp/2238/src/ > > Maciek.

re: media: Unix's Founding Fathers

by dmr＠plan9.bell-labs.com

At this instant, there is an accessible link at http://www.economist.com/printedition/displayStory.cfm?Story_ID=2724348 though it has some popups. A very nice story indeed. I talked to the author (Konstantin Kakaes) for a couple of hours in March. He really did want to know mostly about the kind of things the article talks about, and though the PR guy had probably told him that I wouldn't get into things like SCO, in fact that wasn't what he was interested in.

media: Unix's Founding Fathers

by Corey

Good article in the June 10th issue of the Economist that may be of interest to TUHS members (I would have caught it sooner, but I'm a little behind in my reading). Unix's founding fathers Jun 10th 2004 From The Economist print edition Dennis Ritchie invented C and was one of the key members of the team behind Unix - two developments that underpin much modern software http://www.economist.com/displaystory.cfm?story_id=S%27%2980%2EQQ7%27%23%40… Subscription or "pay-per-view" required. I'd share the full article, but I am afraid of their lawyers. ---corey

Re: History of "sno" Snobol interpreter (V4, Sys V?)

by dmr＠plan9.bell-labs.com

Shoppa wondered, Can anyone comment about the history of the "sno" Snobol interpreter that seems to exist in V4 (man page in the archives gives 2/7/93 as the date) and some later Unix versions (Sys V, V6, etc.)? In the TUHS archives we have the V6 sources but they are remarkably comment- free. Was "sno" ever part of the build chain of any interesting utilities etc? Not that I know of; I think writing it was just a quick entertainment for Ken. The "application" that has survived is a 1-page program that solves the Soma (or Instant Insanity) puzzle. Dennis

History of "sno" Snobol interpreter (V4, Sys V?)

by shoppa＠trailing-edge.com

Can anyone comment about the history of the "sno" Snobol interpreter that seems to exist in V4 (man page in the archives gives 2/7/93 as the date) and some later Unix versions (Sys V, V6, etc.)? In the TUHS archives we have the V6 sources but they are remarkably comment- free. Was "sno" ever part of the build chain of any interesting utilities etc? I'm just generally curious about awk predecessors, if anyone wants to chime in with their favorite pre-awk string processing tools. Tim.

Hi >If the source code was in fact modified by Lions, are there any machine-readable versions available? The source is not modified by Lions, aside some layout and commentary changes. You can find it at http://www.tuhs.org/Archive/PDP-11/Distributions/research/Ken_Wellsch_v6/ By the way, the V6 documentation can be viewed at http://www.ba-stuttgart.de/~helbig/os/v6/doc/index.html Have fun, Wolfgang

386BSD & NetBSD 0.8

by Jason Stevens

Hi, I have one question about 386BSD & NetBSD 0.8... If I'm right the reason that they were 'pulled' was because of infringing AT&T code. However didn't you need a 32v license to get access to 4.X BSD? So in that case since 32v is now public wouldn't that allow these early self hosting BSD's to be 'free' again??? Just wondering...

Multiple system call sets

by dayton＠brooklyn.cuny.edu

Folks, I am interested in the use of multiple system call sets in Unix systems. I recollect that Pyramid Technology machines in the 80's allowed users and/or processes to select whether to use BSD or SYSV system call semantics. Also, FreeBSD supports Linux system calls and SYSV in emulation. Does anyone know a good location (book, article, website) that discusses this. thanks dayton Dayton Clark CIS Department dayton(a)brooklyn.cuny.edu Brooklyn College/CUNY 718.951.4811 Brooklyn, New York 11210 718.951.4842 (fax)

RE: [TUHS] Sprite

by Aharon Robbins

I think you're confused. The DECstation was made by DEC, but used a MIPS processor, not a VAX. SIMH won't be able to do anything with it, although there are likely other MIPS simulators out there to be found.

Re: [TUHS] Sprite

Jose, TNX for parking Sprite on ftp.es.embnet.org! I just ran into a little problem.. looks as if the node is either down, or not reachable (at least from here (== Plano, Texas): $ ping ftp.es.embnet.org PING bakalao.cnb.uam.es (150.244.80.6): 56 data bytes ^C --- bakalao.cnb.uam.es ping statistics --- 9 packets transmitted, 0 packets received, 100% packet loss $ ftp ftp.es.embnet.org [2 minutes later] ^C$ > generated an ISO from the raw CD and am copying now the CD > contents to disk, which are being made available as > > ftp://ftp.es.embnet.org/pub/misc/TUHS/sprite > and > ftp://ftp.es.embnet.org/pub/misc/TUHS/sprite.iso > > as the copying is done. Beware, it is ~530MB. This goes for both my machine at home, and here at work. Now, www.es.embnet.org responds fairly fast, so I don't think that it's the wire across the big pond. Any ideas? TNX!

Sprite

by José R. Valverde

Would it make sense to add Sprite to the Unix Archives? To me, yes, it was enough UNIX like although it wasn't ATT or BSD derived and it had many advanced features. I had the (small) pleasure to run it on a small number of DECstations back in 1994-1995 out of the freshly published WalnuCreek CD and I still long for some of it features. The distribution is still available at http://www.cs.berkeley.edu/projects/sprite/ j -- These opinions are mine and only mine. Hey man, I saw them first! José R.

But I guess I'm a little biased because I like p4 better > than bk. Both biased and incorrect. There are over 10,000 branches of the linux kernel floating around in BitKeeper (we know, we counted them) and we handle file movement much more nicely than perforce does (we have our own concept of an inode, a pathname is a attribute of an inode just like contents are an attribute of the inode - so you can move A to B, I modify A, you pull from me and the changes apply to B in your tree.) You can be as biased as you want, I don't want to turn this into a SCM discussion, but try and be accurate. About the only thing that p4 does that we don't do is centralized locking; we don't need to do that in a distributed/replicated system but people sometimes want it. -- --- Larry McVoy lm at bitmover.com http://www.bitkeeper.com

Grokline: Tracing the history of Unix IP

by Chris Palmer

Maybe everyone here already knows about this, but I haven't seen anything, so I'm posting it. http://www.groklaw.net/article.php?story=20040524130757328 "We hope with this Grokline project to be able to identify any conceivable legal issues that those wishing to block, slow, hobble or tax GNU/Linux may try to use in future legal assaults on the community. If there are litigation risks, even just from nuisance lawsuits, particularly with respect to patents, we want to find those risks, hopefully before they do, and mitigate or resolve them now. I am personally convinced, as you no doubt are too, that the next wave of attacks on GNU/Linux and the GPL will involve patents." -- http://chris.nodewarrior.org/

[pups] E11 and versions and I/O devices

by Gregg C Levine

Hello from Gregg C Levine I've got a bundle of questions regarding E11, and its range of I/O devices. Here goes: 1) Is anyone running the DOS/Windows version with the Display Register device attached to a LPT port? Where did they obtain the LED devices for it? 2) How did they configure its interpretation of the PDP-11 serial devices? 3) Or the network connections? Favorite Ethernet cards as well. And last but not least: 4)Which printer arrangement was used? Serial? Even a parallel solution? To be honest I haven't seen any action on both lists with in the past number of days, so I thought I'd post something new to the PUPS list, and give it something to chew on. ------------------- Gregg C Levine hansolofalcon(a)worldnet.att.net ------------------------------------------------------------ "The Force will be with you...Always."
