   1 - I've got some X programs that I run under 4sight(3.3.2), 
specifically they are POV-Ray and Radiance, both of them attempt
to make private colormaps so as to use all 256 colors, however,
when running under 4sight they for some reason cannot. If I load
up real X-Windows it works fine. Is this a problem with 4sight or
the other software?
   2 - I have a 4D/20 that I bought used, I have found that two
of the plastic SIMM holders are broken, one is totally broken(both
clips), the other only has one clip off. The SIMMs do not stay in
very well at all. I am constantly crashing. Anywhere from 1-5 times
a day, 4sight may freeze or I might get a kernal panic. I taped
them in securely once and the system stayed up for 4 days straight
and then the tape came undone and it crashed. Now I can never seem
to tape it as well and I'm crashing a few times a day again. Does
anyone have any suggestions on how to make them stay in or solve
my problem? I don't have enought money to pay for another mother
board so that's out of the question.
   3 - I have an HP DeskJet 500, will TeX or any other non-commerical
program support it in b&w mode?    

Thanks in advance for any help.

1) The Indigo comes with 1 AUI port for ethernet connection. Is there an
upgrade to add a second port to the machine?

2) I have an Iris 4D/20 with 8meg of RAM. I want to upgrade to 16.
Could somebody send me the type of chips needed and a good place to
purchase them. (Inexpensive)

I would appreciate the responses be mailed to the address below. Not

It sounds like you are trying to use media with 1024 byte sectors,
at a guess.  That *should* work for the raw drive, unless I broke
it in subsequent changes, or the new firmware on the Tahiti isn't
reported the sector size correctly.

The other possiblity is that you have a cable that is too long, or
not good, or that there is no termination on the Tahiti.

- Can somebody explain to me what the difference between shared and 
- exclusive locks is (LOCK_SH/LOCK_EX in flock()).

Shared file locks prevent other processes from writing the file, but they
can still read it.

Exclusive locks should prevent other processes from reading the file, as
the locking process is about to change it.

Thus when you want to modify a file, you should 

    o  obtain a shared lock
    o  read some information
    o  release the lock
    o  modify the information as desired

    o  obtain an exclusive lock
    o  re-read the information
    o  compare it with the previously read one
    o  if the compare fails but the differences can be consolidated, do so
    o  if the differences can not be consolidated abort the update
    o  if the compare is ok write the information back
    o  release the lock

The first lock ensures nobody else actually modifies what you read while
you read it, the second lock stops other people reading information which
will soon be out of date.

The two stage process is necessary when the modification takes a significant
time, for example when fields are updated in terminal interactions. It could
be that the user is shot without finding time to close the transaction 
properly, leaving you with a database you can no longer modify until you 
clear the lock manually or reboot the system.

In client server environments there is often a specific server process that 
locks the file exclusively. All other users have to talk to the server to 
get read or modify access to the data, and the server serialises all the transactions.

This way a definciency of the unix system (only file locks, no record 
locks) has been turned into a must-have asset - support for client-server
environments and all that.

Sounds like  you never partitioned the drive.  dvhtool normally
asks for nothing like that.

Run fx on the drive (under unix), and initialize the volume header
and partitions (fx does that automatically if it doesn't find
the volume header), then exit and answer yes to the question about
writing the changes to disk.

Then dvhtool and mkfs will work.  I'm assuming that you *did*
specify the other disk number, otherwise you were copying sash
into your current system disk, and there should have been no
problems.

mkfs /dev/rdsk/dks0d1s0
mkfs /dev/rdsk/dks0d1s6

Will make the 2 'standard' filesystems for an SGI system disk.

Subject: delobj bug? in maint_dev 4.1
Date: 16 Dec 92 15:07:06 GMT


Hello,
I recently had an opportunity to test some software on a demo Crimson VGXT.
I ran across a software bug that I have been unable to duplicate on any 
other machine.  The bug involved a segmentation fault or bus error in 
delobj().  I am pretty sure the object was OK, because

  1. I could see it on the screen.
  2. the calling code looked like: if( isobj( obj ) ) delobj(obj);

A run of versions showed the maint_dev 4.1 was installed.  Is this an
SGI internal release at this point?  I am only running with 4.05 which
could explain why I haven't been able to duplicate the bug.

I appologize for not giving more detail, but I only had access to the 
machine for a very short time (a couple of hours) and didn't realize I
couldn't reproduce the problem until later.

There are two possibilities:  One possibility is that the
directory that you have put the executable in is not in your PATH, in
which case you will always have to type ./<executable name>.  Another
possibility is that this directory is in your PATH, but not in the
hash table since you put it after the shell was started.  In this
case, you need only to execute 'rehash' and the executable should be
available without typing any path info.

We have a collection of SGI machines (IRIX 4.0.4) mounting each others
disks using NFS soft mounts.  One machine went down unexpectedly, but
in spite of being resurrected has left the others with "Stale NFS File
Handles", which we only seem able to clear by rebooting the other
machines.  We've tried unmounting and remounting the disks, but get
the stale file handle message whether we use the file system or the
directory name.  We've looked through the NFS Administration Guide
and greped the online release notes for "stale", but haven't found
anything pertinent.  Is there a less drastic method for clearing these
stale file handles?

It turns out to be even easier than one other responder suggests.
I've never seen documentation that admits this (so it's probably
totally unofficial), but every version of nslookup I've ever tried
will accept:

	nslookup <<EOF
	set q=ptr

	EOF

That is, you don't need the shell-game to reverse the address and add

We have 4 workstations and they are tightly coupled with NFS and NIS(YP).
The server(master) machine is Iris 4D, and clients are Sun4 and Mips.
But, as you know, the NIS without C2 has great security hole.
(If you got the domain name, you could get anything from that domain.)

I have to secure our machines. Please send a E-mail to me if you have

Or, since this is an SGI group, you can type:

For example, for uunet, type:

Blame tar. It (obviously) tries to chown to the other user and doesn't complain
if the chown fails. The Sun fs code restricts chown. The default SGI code doesn't.
Sun tar should behave like the SGI tar and only chown if invoked by the 
superuser.

Now why anyone would want an unrestricted chown is another question entirely.
