How I miss TOOLIO! Now that Suntool is giving way to Sunview (sob!), I think we should all reflect back on all those wonderful structures and pointers that we grew to love. You know, the ones with the unpronouncable (sp?) names. I just don't know how I'll ever be able to write a windowing application without setting "toolsw->ts_io.tio_handlesigwinch" or without incanting the magical phrase "*ibits = *obits = *ebits = 0" in the "toolsw->ts_io.tio_selected" routine. Those were some of my favorites. I'll never miss them (can you say input_imnull? Sure. I knew you could!). -Mark ----------------------------- Date: 8 Jul 1986 13:07-EDT From: Ralph.Hyre@ius2.cs.cmu.edu Subject: Need patch for dbx (Sun-3/160) [urgent] The symbol table size is too small for a system we're developing with 'too many' subroutines, so we need to increase it. Sources would be most helpful, diffs or patches we can apply using any debugger (adb,sdb,dbx?) would be welcome too. - Ralph ----------------------------- Date: Thu, 3 Jul 86 15:45:23 PDT From: sdcarl!otto@ucbvax.Berkeley.EDU (Otto A. Gygax) Subject: CADroid library I am looking for CADroid board definitions with regard to VMEbus specs. and possibly related connector and component libraries. Any CADroid user willing to share and establish a trade of library definitions with us or among other users, please reply to Otto Gygax University of California, San Diego Center for Music Experiment Q-037 La Jolla, Ca. 92093 619-534-0183 {ucbvax,ihnp4,akgua,hplabs,sdcsvax}!sdcarl!otto Thanks in advance. ----------------------------- Date: Mon, 7 Jul 86 19:29:49 EDT From: cjh@CCA.CCA.COM (Chip Hitchcock) Subject: fps Has anyone gotten fps (fast version of ps, by Royappa at Purdue) to work completely on a Sun? I find that "fps ax" (or even simple fps if I'm root) frequently gets one or more msgs of the form fps: cant read u for pid NN from /dev/drum . I can see that what's happening is fps is somehow not getting hold of processes that are swapped out (at low loads, most of the PID's are in the range 60< NN < 100, corresponding (according to ps) to processes that are started at boot time and trivial amounts of CPU), but I don't know nearly enough about C, architecture, etc. to understand why this loses on a Sun and not a VAX and whether anything can be done about it.

Scott@vlsi-a) Subject: Generic SMD disks on a SUN3 Has anyone got any experience putting non-eagle SMD drives on a SUN using a Xylogics 450 controller. I've got a CDC drive just burning a hole in my machine room floor that I would love to connect to the SUN. So far, my luck with the drive has been all bad. It seems that the SMD interface used by the eagle and that used by the CDC drive is not the same (everyone should have at least one standard, namely their own). ANY information, good or bad, is welcome.

(it happens on both sun2/rel2 and sun3/rel3.) is this a known pty bug? is there a fix?

Recently I changed the name of one of our Sun-3's (running Sun 3.0; we've also got a Vax-11/750 running 4.2bsd on the same ethernet, for whatever that may be worth). What used to be called "a" is now "alanine". To make this change, I edited /etc/{hosts,ethers} on the master yp server (wombat), ran ypmake, and edited nd.local on alanine's ND server (goober, also a slave yp server). I also edited /etc/rc.boot on alanine to change the "hostname=" line. Ever since then, strange things have been going on. If I try to reboot alanine, it hangs with "tftp timeout" until I run "/etc/nd < /etc/nd.local" on it's ND server again. Alternately, I can do an "arp -d alanine" on goober and that allows the boot to continue. There definately seems to be something wrong with arp. For example, looking at goober's arp table right now: goober% /etc/arp -a glutamine (192.9.200.16) at 8:0:20:1:ff:f5 wombat (192.9.200.1) at 8:0:20:1:4f:2b temporary glycine (192.9.200.17) at 8:0:20:1:ff:f6 histidine (192.9.200.18) at 8:0:20:1:ff:f3 uracil (192.9.200.6) at 8:0:20:1:5e:30 temporary clone (192.9.200.11) at 8:0:20:1:47:ed alanine (192.9.200.12) at a:0:0:0:0:0 <====== this is not kosher! arginine (192.9.200.13) at a:0:0:0:0:0 <====== neither is this! asparagine (192.9.200.14) at 8:0:20:1:5e:96 cysteine (192.9.200.15) at 8:0:20:1:ff:f4 Arginine is a new machine which came on-line after the alanine name change. Not terribly unexpectedly, I can't do an rlogin from arginine to alanine, or vice versa -- I get "Connection timed out". I can, however, rlogin to goober (or any of a number of other intermediate machines) and then rlogin to the previously unreachable host. Even stranger, if I do an "/etc/arp -a" on arginine, I get the following: arginine% /etc/arp -a wombat (192.9.200.1) at 8:0:20:1:4f:2b temporary goober (192.9.200.10) at 8:0:20:1:4f:5d temporary alanine (192.9.200.12) at (incomplete) temporary So, what did I do wrong? ----------------------------- Date: Wed, 2 Jul 86 01:12:25 PDT From: fluke!jeff@uw-beaver.arpa (Jeff Stearns) Subject: Simulating kernel memory mapping OK, hackers, can anyone out there correctly describe the function which simulates kernel memory mapping on a sun-2 (and a sun-3) running release 3.0? In other words: Suppose you have a keen program which pokes around in memory to decode some interesting kernel data structures. Your program nlists /vmunix to build a symbol table of kernel addresses. It uses these as seek offsets into /dev/kmem to read the data. Then one day you realize that it would be very valuable to run your program to perform an autopsy on a crashed system. So now you have a vmcore file. There is a mapping function whereby your program's kernel addresses can be mapped into seek offsets into this vmcore file. What is this function? You have 30 minutes. Hint: It is NOT the same as that which works for 4.2BSD on a vax. Jeff Stearns John Fluke Mfg. Co, Inc.

I'm looking for information regarding Stanford University's "V" System real-time operating system for Suns. We'd like to consider this as part of the vision system for the ALV (Autonomous Land Vehicle) project at Martin Marietta Denver Aerospace. I'd appreciate any information about implementations of "V" on Sun II and III, and general comments from users. Thanks in advance!
