I once borrowed a 3/60 from Sun (UK) and the SCSI connector on the cable had one pin snipped off, I don't remember wich one, but it didn't look accidental. Does this mean the above caveat also applies to 3/60's? Also, can one blow a _Sun_ drive by using a non Sun cable ? Tim.

If you look at the standard unshielded SCSI connector pinout (two rows of pins, 0.1" spacing), you will see that pin 25 (using the standard flat cable conductor numbering convention) is on the grounded side of the connector and is opposite pin 26 (terminator power, ~5v). People have several sloppy habits, including plugging cables in backwards. Therefore modern SCSI specs say that pin 25 should left unconnected and pin 26 should be fused. The obvious mistake that one might make in a SCSI interface is to ground pin 25. If the "Read Me First" that comes with a sun-4/110 is to be believed (pin 26 grounded), someone really botched it. Perhaps the "Read Me first" is incorrect. I think someone from SMI should post an explanation to Sun-Spots digest. P.S. SCSI devices do not always supply terminator power to pin 26. The feature is optional, usually selected by a jumper or a switch which leaves pin 26 unconnected if the feature is not selected. If a SCSI device has internal terminators, they are probably powered internally. SCSI host adapters usually have internal terminators. SCSI systems may work ok even if one end of the cable is not terminated or there is an extra set of terminators on the cable. Many non-SMI SCSI devices would work ok on a sun-4/110 even if pin 26 is grounded. Some would burn up. ------------------------------ Date: Sat, 3 Sep 88 23:15:35 EDT From: John T.

Ooooh boy does THIS sound familiar! I have the same problem, however I tried [[ the fix from bien@aerospace.aero.org ]] (changing the hosts.equiv file) and it STILL doeosn't work. That's right... even when the official host name of the machine is first in the hosts.equiv file, I still get connection closed. Here's the interesting part: One of my machines is a 3.5 machine and the other is a 4.0 machine. I can rsh and rlogin from the 4.0 machine into the 3.5 machine but NOT from the 3.5 machine to the 4.0 machine. I suspect there is a more complex underlying bug in there than we suspect (i.e. just changing the ordering of entries in a file). SunOS is begining to remind me of Symbolics Genera 7.X. The switchover to the new grand improved feature-filled (and SLOW) Genera 7.X was horrendous for Symbolics users. I hope Sun is smart enough not repeat such a mistake (but 4.0 doesn't give me much hope). John T.

SPE is a step in the right direction for bringing some of the power of the Symbolics' lisp development environment to the Sun. It has an improved editor (but face it, nearly _anything_ would have been an improvement over the Lucid sub-emacs editor :-( ). You now have a little bit more of a mouse interface to the editor, and can do the equivalent of CTRL-Shift-A to get the arguments of a function by mousing on a help item. (Note to the developers of SPE: It would be nice to also be able to do the equivalent of CTRL-Shift-D, get the function documentation string). There is a scrollbar. You can mark & compile regions. There is much functionality that I would still like to see added to the editor (I use GNU as an example of a full-featured EMACS.) Chief complaints about the editor: 1. You still can't save keyboard macro definitions to a file!! 2. The mouse interface is still sparse. 3. The documentation could stand fleshing out. 4. It's obviously immature. I feel the most powerful feature of SPE is going to be the debugger, especially when _it_ is little more mature. In SPE you now have a true source level window-based debugger and an inspector that will allow you to look at local variable bindings (finally! This has been a chief bitch of mine regarding the crummy Lucid debugger.), arguments, or any object at all, for that matter: arrays, lists, function definitions, etc. There are a couple of other goodies that come with SPE: an application planner and something else that I can't remember. Suffice it to say that I haven't used them yet. One of the other folks in my group has used the application planner & says that it's nice. He'll probably see this note & follow up on it. Time for a short tirade: Prior to SPE I estimated that it took ~3X (yes, THREE TIMES!) longer to develop a large lisp application on the Sun as it did on a Symbolics. This due to the powerful editor & debugging facilities provided by the Symbolics' environment (and lack of same on the Sun, of course). I feel that this discrepancy in productivity is diminishing now that SPE is out. The tirade: (unfortunately aimed at a large audience & probably only meaningful to a small part of it, those of you who use KEE [Knowledge Engineering Environment, a product of IntelliCorp, Mountain View, California] on your Suns) -- SPE doesn't do _us_ any good, because most of our lisp work is done from within the KEE package, and Intellicorp doesn't seem to be in any hurry to provide its customers with a version of KEE running on top of SPE! End of Tirade. Hope this helps. --Doug Douglas Roberts Los Alamos National Laboratory (505)667-4569 dzzr@lanl.gov ------------------------------ Date: Mon, 5 Sep 88 13:54:44 CDT From: thompson%umn-ai@umn-cs.cs.umn.edu (William B. Thompson) Subject: Re: colormap segments The Sun color frame buffer on our 3/110C allows text and images to coexist by supporting separate 8 bit color and 1 bit mono frame buffers, along with a 1 bit multiplex array to specify which frame buffer to use for every pixel. If the mouse is in a window used to display an image which requires a full 8-bit color map, all is well -- both the image and any text windows look as they should. Move the mouse outside of the image window, however, and SunOS loads a color map which causes the image to disappear. This occurs even if no other windows are using the color map. The disappearance of image windows is unavoidable with the traditional 8-bit frame buffers. The 3/110C maintains compatibility with these older designs at the expense of significantly decreasing the utility of the 10-bit frame buffer. Perhaps Sun would consider some sort of switch to enable a more sensible behavior? William B.

The problem is that patching the 4.3 BSD csh to get tcsh and trying to get it to run on a Sun is not working (e.g. Control-C on a blank line causes tcsh to die with 'exit 1'). Patch fails over 50% of the time if the 4.3 patches are applied to SunOS 3.5. Do SunOS 3.5 csh patches for tcsh exist?

I have used SUN's expansion "ie" card, but for various reasons don't want to use it in what I am doing (eg, I need it to be a standard-size VME card). I don't really want a card with a processor on it since the networking is in the kernel, and the only ones I know of offhand are front-end processors. So if anyone out there knows of a good, fast (ie, NOT the 80586 chip) VME Ethernet card, ideally with a driver for SunOS 4.0, I'd love to hear about it. -Mike O'Dell uunet!mo ------------------------------ Date: 4 Sep 88 23:53:31 GMT From: munnari!sirius.ua.oz.au!mrp@uunet.uu.net (Mark Prior) Subject: SL/IP is broken if used with ALM-2's Reply-To: munnari!sirius.ua.oz.au!simon@uunet.uu.net (Simon Hackett) The story so far: We have 9 or so Sun-4 servers and 50-60 Sun-3's here (I loose count). On all but one Sun-4, we have ALM-2 multiport serial boards. Most of these systems are distributed around the campus, and most of them are on ethernet. However, that ethernet hasn't got to all the campus buildings (yet). We have multiple locations housing Sun-3's and PC's which we wish to connect to the network via Serial Line IP (which I'll call SLIP from now on). Sun "support" this with the addition of some patches, which come on the PC-NFS 3.0 distribution disks. With these patches applied to a Sun (e.g. one of our Sun-4's), one is supposed to be able to network in Sun-3's and PC's via serial lines. Since there is only one spare serial line on each Sun-4 cpu board (after the console is plugged into the first port), we HAVE to use our ALM-2 boards to link in the SL/IP connections, because we have more than one SL/IP line in use. (2 currently, we'd have more like 2 dozen if this would work) It actually does work initially, but a while after you start using the network link the Sun-4 server crashes, saying 'panic: mget'. This is un-tenable for machines we need to have running for long periods to process compute- intensive jobs. The local sun office says this is a known problem with SL/IP and ALM-2's, where the SL/IP driver and the ALM-2's interrupt priority don't get along. They also say this was fixable with ALM-1 serial boards, but can't be fixed with ALM-2's. We are not very impressed by this, and we are not of the opinion that "we can't fix it" is a good enough answer from a company who says "the network is the computer". That trademark is becoming a sore point around here. Without any O/S source code yet (another sore point), we can't fix it ourselves. The suggested workaround (don't use ALM-2's, use the CPU boards' second serial port) doesn't help us much, when we want dozens of PC-NFS to Sun-4 connections, and probably several more Sun-3 to Sun-4 connects as well. Surely this is a problem Sun can fix. Particularly if there are others in the same situation who can help us put pressure on Sun to act. So: Has anyone else got the same problem? Can anyone suggest another solution? regards, Simon Hackett P.S. I don't want to complain about this. I just want it to work.

Wonder if anybody out there had a similar problem. Here it is: We have an Ethernet-work with three Apollos and several PC`s. We are using TCP-IP, NFS and TELNET. Using the PCI of Apollo is unsuitable for future use because the network will be expanded one day to an university-wide one which will contain Vaxes, Suns and whatsoever. TCP-IP (seemingly) and TELNET work properly, NFS not. Problem 1: An (pure) Apollo-Problem: when booting, nfs does not always start up properly. Usually all processes (mountd, portmap, nfsd) are up and running, the PC-s seem to be partially able to communicate but are not able to access anything. (General error on Drive .......). If I kill nfsd and start it again manually - everything is fine! I followed all the instructions and do not know what to do. Apollo-staff here in Austria seems to be rather uninformed as are their manuals (call this a manual.???) and uninterested (they want us to use PCI but we do not). Anybody some help available? Problem 2: As Apollo stated: NFS is supported for use in an heterogeneous network together with suns. If we had a sun, it would be responsible for authentication. We have none. We have the PCNFSD-sources which we are unable to translate because there are some .h-files and rpc-routines missing. And I do not know how to access the passwords which are not stored in /etc/passwd. How can I do authentication? Fear, nobody else had this problem. But: any ideas how to authorise users more than user.none.none.none.....??? Apreciate any responses - pleas use email!
