Someone sent me email to the effect that AIX provides a new signal,
SIGDANGER, for this situation;  SIGDANGER can be trapped.  On the
other hand, AIX doesn't allow you to modify the kernel to reinstate
the old behavior.

I have a question:  does this bind-real-space-on-access scheme also
apply to statically allocated arrays?  For example, if I have a
large Fortran program which statically allocates arrays too large
to fit in phys+swap, but I only use part of them, will this program
also load uneventfully, but die if I try to access what doesn't fit?

And now that I come to think of it, isn't this the way VMS works?

Hi, SGI users...

I am trying to locate the C command in IRIX 4.0.1 to
pop up (bring to the foreground) the window shell from 
which the program was called. I recall it existed in
3.3.2, was called tpon, for C and Fortran. Now, tpon
is only for Fortran in 4.0.1 And I tried every man -k
I could to locate such a function in C. Can anyone tell
me where to find this? (and the versions correspondent,
maybe I didn't load it, although I ran trough the versions
installed.)

Thanks a lot.

	He is running a series of SGI 4070 workstations under IRIX 4.0.x.
He wants to be able to create X-Window sessions from a VAX running VMS v5.4-3.
Local clients are extremely slow, unless he turns off the "BLTscroll"
function.  When he tries to create a client from the VAX to the SGI server,
it too is unacceptablly slow.  He tried explicitly declaring the BLT parameter
in the DECTerm resource file, but it had no effect.

	Can anyone please suggest other things for him to look at?

I seem to remember some discussions about MIDI software being developed at
SGI.  Can anyone help me out with the name of a product and/or a person to

Also, how about something to decode SMTPE time code which was being input 
through the audio port of an Indigo.  (I realize the if there is MIDI stuff
available, I could use a SMPTE to MIDI sync converter and then read the MIDI
time code through a serial port... but it would be nice to avoid the extra
hardware if all that was needed was synchronization.)

This is not true.  I haven't tested an 8500 personally, but the

Addison Wesley will be publishing a series of books on OpenGL in the near
future.  The first book, The OpenGL Reference Manual, should be in your book-
stores by Christmas.  It is a man-page like description of the OpenGL functions.
It will be priced at $28.95.  

The second book will be The OpenGL Programmers Guide.  This is a programming
guide (targeted at those with at least some programming experience).  Lots of
programming examples, and detailed color illustrations.  It will be around
650pp, will include an OpenGL poster, and is to priced at $35.95. Available around February of 93.
 

Later releases should include books on IRIS Inventor and Explorer.

Anyone wanting a 20% off coupon for these books should send me an email with
your physical mailing address.  FYI, for those of you who have already sent me
a request, please do not resend.  My administrator should be sending out the
backlog of current requests this week.

Howdy netlanders,
  Another Iris user and I are trying get dog running with two machines on
separate class C nets. Here's the scenario:

1. Both machines have uncommented the line in /etc/services to allow
dog to run.

2. This machine is on 134.136.241.11

3. The other is on 134.136.243.100

4. I think mrouted is what I need, but I dunno. The docs are woefully   
inadaquate on this. They seem to assume the user is familar with what he's
trying to do and just needs a few hints. Not the case, here at least.

So can anyone give me some basic guidance, with small words? What are the
side effects of running mrouted? Seems like all packets broadcast by any
machine on this C net would be repeated over on the other net, and vice-
versa. At least that's what I get from reading the man page.

Try using 'cdman' and 'datman' to record from the CDROM and DAT drive,
respectively.  The aforementioned are standard tools of 4.0.5F.  These

You removed your kernel.  This is the program that supervizes the hardware.
Your system can not be rebooted in its present condition safely.  Your system
will continue to operate indefinitely without this program; but some commands
that are dependent on examining kernel data for the programs' functioning may
not operate or not operate correctly, e.q. `ps'.

I suggest that you execute `lboot -t' immediately, respond `yes' to the
question about automatically reconfiguring your system.  Then, you should
be in a "safe" condition.  Then, as soon as practical, reboot your system.

I have just been itching to say something here.  One could certainly
write a "file expander".  Yes, it would take a bit of work, but it
would not be too hard.  Write a C++ class that redefined read(),
write(), open(), close(), etc.  in a way very similar to the way the 
logical volume software works ( now ) across multiple physical disks.
This does not seem to be a difficult problem, just another layer.

Think about it.  An 8 bit machine must be able to access files bigger
than 2^8 bytes, right?  So this problem was solved during the Kennedy
administration, and forgotten about.  Check out Charle Rupp's latest 
book on operating system theory on why this is an easy problem, and 
( I think ) Tanenbaum's book on MINIX on how to solve the problem.

     I recently attempted to install a CDROM on a Powerseries 360 at 
my site.  The CDROM was installed as the last device on the SCSI bus,
and the system was rebooted.  The system would then crash with different
errors each time.  I assumed this meant that the allowable SCSI bus
length had been exceeded.  There are a number of external devices on
this bus, with 3 to 4 foot long cables linking the devices.  I thought
that by purchasing some shorter (15 to 24 inch) cables, I could possibly
shorten the SCSI bus to an allowable length.  However, I have not been
able to find a vendor that sells SCSI cables of this length, either
standard or custom made.  I've tried Inmac, Misco, Black Box, and Control
cable.  Does anyone know of a source for 15 to 24 inch SCSI cables? I'd
greatly appreciate any help in finding these cables.

Subject: Local network slowdowns
Organization: Wayne State University, Detroit, MI
Date: Wed, 14 Oct 1992 19:02:39 GMT

We have 3 R3K Indigos, a 4D/440, and 2 R4K Indigos on a network. We
have noticed a problem affecting 2 of the R3K Indigos and the 440 that
occurs very seldom, but is very troublesome when it does:
network-dependent functions on the affected machines slow to a crawl,
but the problem seems to be one-way. That is, telnet *to* one of the
affected machines connects immediately but takes over half a minute to
return with a login prompt. rlogin takes about the same time. However,
telnet or rlogin out *from* one of those machines to one that is not
affected doesn't take any longer than normal. Mail behaves similarly:
affected machines are quick to send, slow to receive. The problem
usually disappears spontaneously after an hour or so, and doesn't
coincide with periods of high network traffic.

Another case that occurred just today: all of these machines were
rebooted at about the same time. On one of the machines, which mounts a
nfs volume exported by another, mount reported that the server was not
responding and timed out, but eventually did mount the volume.

The thing that distinguishes the affected machines from those that
aren't is apparently that the affected machines are all running NFS.
However, the 440, which *is* affected, doesn't actually mount or
export any NFS volumes.  We are considering opening a TAC call but
can't reproduce the problem reliably, so we are reluctant. Has anybody
observed anything similar, or might the experts have any ideas as to
what we are doing wrong?

BTW, of the affected Indigos, the NFS server is running 4.0 and the
client is at 4.0.5A. The 4D/440 is running 4.0 also.
