Yes, all SGI workstations have more that 4 colours.  

One possibility is that the CAD program is not dealing properly with the 
many visuals the X server exports.  In particular it sounds like the CAD 
program looks at the first PseudoColor visual, in SGI's case a 2bit 
"overlay" visual, and decides that's what it wants to use.  Later on it 
finds out the 2bit PseudoColor visual has too few colour cells for it to 
work correctly, and punts.  

Had the CAD program been a bit more intelligent, it would have noticed
the 8 and 12 (!) bit PseudoColor visuals a little further along in
the list of visuals.  The CAD program could have even just asked for 
what it really wanted, ie. an 8 bit PseudoColor visual.

Find out for the writers of the CAD program if you can specify which 
visual that it should use.  Then give it the right one, probably the 
8bit PseudoColor one.

>Just how "X" compatible are the SGI's?

Absolutely, positively, completely.  If you find something that isn't, 
it is a BUG and we will fix it.

I recently posted some questions about NetLS.  I got a long reply from someone
at SGI named Allen (whose full name and net address I promptly dumped in the
bit bucket)...  Thank you Allen.

I was eventually able to get the Network Computing Kernel and NetLS daemons
to run.  And was able to use ls_admin to add my CASEVision/Workshop license.
(There's joy in Mudville tonight!)

However, since my posting I have received quite a few bits of mail saying what
a hard time others had installing this system and offering their sympathy.
I just wanted to post to let SGI know that it seems like quite a few rather
experienced UNIX people (myself included) are having a pretty tough time with
this sucker!

I'm not sure out of what manual Allen got the 27 pages of info he sent me, so 
maybe its already out there, but it should definitely be provided to anyone who
is going to using the floating license server.  Or perhaps it could be (or is)
provided via ftp from sgi.com.  Also, it would be nice if the process of 
bringing up the system could be a little more robust.  I ran into quite a few 
different problems which probably would have left a novice UNIX user completely 
in the dark... not all sites have experienced system managers!

Anyway, I'm happy now.  Thanks again.

You're right, of course. Chmod always followed symbolic links. Chown
didn't follow symlinks.

Of course, the same is true (in a limited way) of hardlinks.
Don't do recursive chowns (as root) unless you're absolutely sure.

The chown manual says:
  When the -R option is given, the command recursively descends its
  directory arguments setting the specified owner or group.  When symbolic
  links are encountered, their ownership or group is changed, but they are
  not traversed.

It seems to me that this conflicts with the implementation of chown.
Chown(2) says nothing about following symbolic links.

chown -R does chown the symlinks it finds, that will give some problems.
If your system administrator has the habit of doing:

chown -R user.group ~user/.

``ln -s /etc/passwd symlinktopasswd'' somewhere in your home will prove that
that isn't a good idea.

Since the owner ship of a link isn't important, following it with chown seems
like a good idea. I might be better just to make it a noop.

Owing to the sheer quantity of newsfeeds we get, sometimes we are forced to
purge out the news after its been here only a couple (or three) days.

In addition to the FAQ, an archive site for this newsgroup (if it doesn't
already exist) would be very much in order.  Ideally, something where you
can either FTP the newsarticles, or connect to its NNTP server/deamon and
browse to your heart's content.

One other (potentially) important difference is that the Crimson has two

I have a floppy drive on my PI 4D/20, running 4.0.1, and
I am trying to mount it, to no avail. I am now very
confused by the two commands mount and msdosd, not to say
the system-disk manager. I was able to install the floppy
on /FLOPPY with the disk and file manager, but it won't read
msdos disks. When I try to ls /FLOPPY, nothing happens.
and when using eject FLOPPY, I get :
/dev/rdsk/fds0d3.3.5 not mounted

My fsd.auto and fsd.tab are:

Date: 9 Oct 92 20:17:56 GMT
Distribution: comp.sys.sun
Organization: The Jackson Laboratory


    We have a prototype system that we have been using for efforts in 
automated mouse chromosome analysis. I need to replace some of the equipment,
as I borrowed and begged things from other projects, and I need to return
them. Images under a Zeiss light microscope are captured by a Dage/MTI 66 
Series Camera. The camera output is RS-330 and is feed into an Imaging
Technology Series 150 System which in turn is connected via VME bus to a
Sun-3/110C system. The Imaging Technology System is used only to capture the 
image into its frame buffer, and make this available to the Sun computer in a 
512 x 512 x 256 grey image. The enhancement, boundary identification, object 
recognition and classification are/will be software controlled on the Sun 
computer. Software is wrappered by the Khoros system (John Rasure et al. from 
U. New Mexico) and is C and X based (e.g., portable).

    The microscope and the camera stay. I have to replace the imaging system 
and the computer. One solution is to obtain an Sbus based Imaging Technology 
System and a Sun Sparc. But there might be better configurations. The problem 
reduces to finding a good, and economical, board/imaging system to combine
with a computer. I am partial to Sun and Silicon Graphics systems. 

    Any advice, suggestions, pointers, etc.  would be appreciated. Please 
email replies directly. Thank you.

How would you have "more freedom" by ignoring the setuid bit?

a problem with the resolver.  If I setup resolv.conf, so that name
resolution is enabled, mail and telnet, ftp, etc. all work fine, but the
resolver seems to ignore the entries in /etc/hosts.  When I rename
resolv.conf to another filename so that the resolver only checks the
hosts file, the entries are read correctly.  I have the "hostrorder

Subject: Too many texture maps?
Date: 7 Oct 92 20:05:13 GMT
Distribution: usa

I've got an interesting problem on our 340 VGX:

I have a program that visualizes Cat Scan data. It visualizes it in two
ways: 

  (1) a set of triangles representing a particular isovalue surface -
      for example the bone surface. (Typically ~20,000 polygons).

  (2) three orthogonal cut planes through the dataset where the CT
      data is texture mapped onto 3 polygons representing the CT data.
      Each of the three texture maps is a 128x128 two component texture.


When the program first fires up, it renders the bone surface polygons only, 
but not the 3 texture mapped cutplane polygons. I get about 12 frames/sec.

When I turn on the first cut plane (calls a texdef2(), texbind(), etc) 
all is fine and there is no noticible slow down in rendering frame rate.

When I turn on the second cut plane (a second texdef2(), etc - so that
now I have two defined textures), the rendering speed slows down a little
bit, but not much (maybe 11 frames/sec). It's pretty much what I expect.

When I turn on the third cut plane, the system slows down noticibly (frame
rate is down to about 7 frames/sec). 
This third plane cost me a lot! 

FIRST QUESTION:
Have I possibly defined more texture than the VGX texture planes can hold 
so that I'm swapping texture plane memory?


Now the interesting part: I turn off all three cut planes [I do 
a texbind(TX_TEXTURE_0,0) and tevbind(TV_ENV0,0)] and don't even try
to render the 3 orthogonal polygons that the textures were applied to.
Now no texture is active and I'm only rendering the bone surface again, 
the speed of rendering doesn't return to it's original fast rate.

SECOND QUESTION:
What is going on that would slow the system down now? Why would defining
and using 3 texture maps, and then unbinding all textures result in a 
rendering speed less than before I defined any maps? 
I know that once I turn off all three textured cut planes, that the
program is back to only rendering the bone polys.

NOTE: If I only active the first two maps and then deactivate them - I
return to the original 12 frames/sec. It's only when I the third map (that
slows the system way down) is defined that I can't return to normal.
