Garcia is correct to praise the Hafner/Markoff account of the worm incident. There were some details about the kids' accounts and exploits that Markoff decided to elide; by the time he wrote that chapter he had become rather sympathetic with the Morris family. In 1995 another big incident occurred: the exploitation of the SYN TCP-connection takeover attack (Mitnick etc.) Markoff got another front-page NYT story out of this (and a book with Shimomura). I sent mail to Markoff at the time of the newspaper coverage reminding him that RTM had discovered the basic attack in 1985 (see CSTR 117 at http://www.cs.bell-labs.com/cm/cs/cstr.html ); while here during a summer. Markoff replied in part, >Interesting how often RTM figures, one way or another, in your front-page >stories, and of course the [Cyberpunk] book.... > > Dennis Ritchie yes, this is true. you know i sat there on sunday for about ten minutes and thought about whether i should include rtm in my story - it would obviously have spiced it up. i finally decided not to on the grounds that 1. i have done enough to mythologize him for one decade 2. he is probably entitled not to be dragged through all this again. i still wonder whether i did the readers a disservice... Incidentally, "RTM Sr." was (while here) "rhm" by login name, and always called Bob; I don't think he actually has a middle name (at least I don't know it.) I think it's like Harry S Truman. RTM is called Robert, and never used Jr. About > [Bob] Morris, he said, was the kind of guy who always liked to tinker with > things, and if an object had buttons, Morris just had to push them. > In fact, sometimes Morris was just a little too quick with his fingers. > On one side of a machine room was the light switch, and on the other > side was the power to the machine. > On at least one occasion, you guessed it -- Morris hit the wrong switch. > Some people hung a disk pack that got ruined around his neck, and someone > put up a big sign as a reminder: "THIS IS THE WEST WALL!" I suspect that we may be dealing with the "Schryer filter" regarding some of the details. Norm S. was right about Bob's being an aggressive investigator and fiddler, but I don't connect the west-wall sign with Morris in particular, but my memory could be failing too. Norman Wilson might have been around for advent of the sign. In the event, it had more to do with circuit breakers labelled in small print "east wall" and "west wall" and someone choosing the wrong one. Dennis

RE: [pups] Ultrix-3.1 boot tape inside the PDP-11 distribution directory

Ultrix-11 runs fine on SimH, with the "downs" that because SimH does not do detailed and correct CPU emulation, Ultrix gets confuzed every now and then, which does not happen with E11. I am preparing a new (V3.2) release of Ultrix-11 which has major changes, including: - full system regeneration off single source tree - full RAxx support - addition of VTserver, TDU and compress - compressed manual pages and documentation - Y2K support (not just date(1) ;-) The installation procedure has also changed to a more modern style. I don't have much time right now, so progress is slow. The above is "done", though. If you need help with Ultrix-11, pse contact me off-list. --fred

[pups] Ultrix-3.1 boot tape inside the PDP-11 distribution directory

by Gregg C Levine

Hello from Gregg C Levine This is both my first post from this address, and a couple of questions. Question 1) Has anyone actually followed the instructions and description of same, found inside the readme file found in the directory? Question 2) Was this on actual hardware? Or inside the Simh simulator? Or even with one version of E11? In my case this will be inside the Simh simulator, and I am basically working straight from the beginning. If all goes well, I'll move it to the E11 one. ------------------- Gregg C Levine hansolofalcon(a)worldnet.att.net ------------------------------------------------------------ "The Force will be with you...Always."

Actual names of boot images versus names listed in readme file for boot_images

by Gregg C Levine

Hello from Gregg C Levine I found out, on my system, and borrowing the Cygwin tools for file manipulation, the actual file name for .2,9BSD_rl02_1145.gz, it is rl02_2.9BSDroot, so I used that name in place of the one suggested inside the readme file. It works the same way. However, this is just the root collection. Is there any other pack available that contains the other members of the entire 2.9BSD system that provided us with this one? Also this was done with version 2.9-11 of Simh. So, when you get a chance, Warren, you can update the readme, and upload the appropriate file to the directory on your server. Oh yes, this came from a mirror of your site, its the one on ftp.tux.org Gregg C Levine drwho8(a)worldnet.att.net "Oh my!" The Second Doctor's nearly favorite phrase.

Pack found in Tim Shoppa distribution but not listed

by Gregg C Levine

Hello from Gregg C Levine This is something that is totally different then what I first reported on regarding this distribution. In the readme for this one, it mentions everything list inside the directory, except the one marked down as "Unlabeled", and it originally came on a RL02 type diskpack. It is not listed in the Readme. Obviously it is what it says it is, an unlabled diskpack that Tim recovered the same day as the others, and those are indeed present, and listed. Except obviously the one that I first reported, that one isn't mentioned, and not there. That subject is done. I am just reporting on "Unlabeled", as far as everyone is concerned, is there anything on it? Or is it an empty pack? Gregg C Levine drwho8(a)worldnet.att.net "Oh my!"

Re: [TUHS] Can someone advise me regarding a gui for UNIX

by Aharon Robbins

Another reason the 5620 was botched so badly was that AT&T wanted >= $2000 for the development kit (read: C compiler and libraries) for it. Not a good way to get lots of 3rd party application developers on your bandwagon. I used one for a year or so; it was the first windowing system I'd used and the only one I've really liked. For about 10 years I've been using 9wm, which gives a similar feel (at least to me). Those who want to go all the way should adopt 9term as well. (I generally run xterm + bash these days, although for a long while it was 9term + es/rc.) Somewhere, I have an X version of the 5620 font. I found that it wasn't so pretty. I've been using the pelm-latin1-9 font from the sam distribution for years. Norman forgot to mention that the most long-lived split-design application is Rob Pike's sam editor, still available for X11 and still in use on Plan 9. Arnold

Re: Can someone advise me regarding a gui for UNIX

by Brian S Walden

Another hurdle for the 5620/630/730 lines of terminals was when I tried getting software support. Teletype being a mostly a "dumb" terminal manufacturer never considered them more that a way to have multilple 80 char x 24 line terminals on one display. I had difficulty in conveying to them that it was a computer in its own right and you could program it. The marketing was probably just as limited in scope. Another blow for the BLIT portion on the terminal came when you cound get an external cartridge for the 730 that turned it into an X-terminal. I got mine in 1991 and then rarely used layers after that. -B

Re: Can someone advise me regarding a gui for UNIX

by Dennis Ritchie

Norman Wilson's account of the Jerq/Blit etc. is quite complete and correct, though there was some recycling of names. 'Jerq' actually was used quite early, when Pike got interested in bitmap graphics. The name was a takeoff on the Three Rivers Perq, which he (and I) saw at Lucasfilm Ltd. while attending an early Usenix. Blit was the slightly more PC version (suggested either as part of BitBlt or "Bell Labs Interactive Terminal). The originals used the Motorola 68000, and part of the development messup was AT&T Computer systems' decision to switch to the WE32000 processor with consequent delay for porting and reworking. The earliest versions were not quite as wonderful in practice as Norman suggests for the later ones. They were built by the Teletype corp. model shop (in quantity of a few hundred) and downloading the OS took several minutes at 1200bps--necessary at startup, since they didn't have a ROM for the whole thing, just enough for doing a download. They were also static electricity antennas! Many is the time that I would shift in my chair, then touch the keyboard, only to have the terminal reset itself. I developed the habit of putting my hand on the heavy steel case before moving around. On the other hand, the basic idea was architecturally right (and the later commercial versions were not so subject to static, and had ROM for the OS). They were even nicer at 9600bps. It's good to know that Norman is still using his. Dennis
