No, the PROM monitor knows nothing about RIP, GATED, or any other
routing protocol.


To remotely boot, the intervening gateways must be willing to forward
both the initial RFC-951 "bootp" packets and the later TFTP UDP
packets.

No useful router has troubles with TFTP UDP.  However, over loaded
routers can drop too many packets to be "useful".  It is not hard to
overload routers today, including Ciscos.

The most likely source of problems is in forwarding the initial BOOTP
packets.  Many routers do not forward BOOTP at all.  Others, notably
Ciscos as of a year or two ago, have different ideas from Silicon
Graphics on how and when to forward BOOTP packets.  The Silicon
Graphics "Information/Services" organization has long preferred Cisco
routers over Silicon Graphics boxes over the strenuous and bitter
objections of Silicon Graphics' sales and engineering.  For years the
internal rule of thumb was that you must ensure that you have IRIS's
acting as routers available to forward BOOTP and to gateway for timed.
(No one, including the main SGI timed proponent, me, would expect Cisco
to support the timed protocol, "TSP".)

There are also problems if the machine from which you are booting is
"multi-homed" or has more than one network interface, caused by
disagreements between the client and the server over the server's
hostname.  We have improved that in IRIX 4.0.5.  If this is the problem
(unlikely), ensure that you are net-booting from the "nearest" alias of
the server, possibly as in "gate-load-host" instead of "load-host".


More recently, many people have found a somewhat inefficent but very
easy and effective solution.  Simply NFS mount the distant images on a
nearby NFS server.

WIth the advent of automount, this is as easy as:

    0.  install NFS everywhere
    1.  turn on automount on all nearby IRIS's
	`chkconfig automount on`
	`reboot`
    2.  boot specifiying the NFS images, as in

	local-server:/hosts/load-host/CDROM/...

A programmer here needs to use dbx, which requires the /debug
filesystem to be mounted.  The trouble is, the man page on
dbg/debug doesn't explain how to mount it, and neither does
the man info on fstab.  I don't see any candidates for mounting
in the /dev directory.

How do I mount /debug?

Quickpaint will not run under IRIX 4.0x.  Don't worry -
t's not a big loss, since it did not support painting
on 24-bit images.

If you'd like to add text to your snapshots, you can
import them into Showcase, then add text using the
Text tool.  If you need to get the result back into
an image file, then simply snapshot the showcase
display.  Make sure you choose "Full Color" from the
Showcase menu before taking snapshots of the Showcase
display.

If you'd like to do some simple image processing, such
as blurring, sharpening, resizing, or adjusting
brightness/contrast of an image, check out the
"imgworks" program, found as part of the ImageVision
Tools.

If you need to paint on an image, I suggest you obtain
a copy of "imp - The New Impressionist."  It's a
painting program written by our own Paul Haeberli,
which allows you to paint and retouch images in a very
natural and realistic way.  But its main feature is
the special effects it offers, including the ability
to paint impressionistic caricatures of any image.
Imp is included on the "Totally Insane" CD, which
was offered at the Developer's Forum, and can be
obtained via anonymous FTP from sgi.sgi.com, as the
file ~ftp/graphics/bin/imp.Z.  For a look at some of
the graphics techniques employed by imp, check out the
paper "Paint By Numbers: Abstract Image Representations"
by Paul Haeberli in the SIGGRAPH '90 proceedings.

If you need a full-blown paint, image editing,
image processing and photo retouching package, you might
consider purchasing Creative License from Time Arts,
or Digital Artist from Digital Arts.  Both are very
capable full-color image editing/paint applications.

Hope this information helps.

We are a group of 20 users in 3d imageing envoirenment. We plan to buy the
new INDIGO R4000 machines. We would like to use on of the machines as a file 
server. All users home directories will be NFS mounted to other SUN SPARC1s  and
the new INDIGOs. I am concerned about disk I/O performance in such a setup.
(Disk will be 1.2Gb FAST (?) SCSI )

Does any one haave any experience in this type of setup. 
(using INDIGO R3000 or R4000 ) :
   -How well does it perform in terms of NFS activity ?
       (our data files are usally 8-16Mb)
   -Wil there be any problems if we also use the server for normal computation
    and graphic display. ?

Your suggetions or comments in this matter will be greatly appericiated.

Advice sought for
	Attaching character string labels to networks in GL.

Right now we are using the triad:
	font()
	cmov()
	charstr()
which has the advantage of maintaining good viewing angle and size 
during translation and rotation, but has these problem:
	1). zbuffering does NOT work so front labels may be occluded by
	    back labels.
	2). sizes are constant.
	3). lables always orient left-right horizontally.

We have not tried the so-called stroke fonts by actually drawing polygons,
and it is assumed the maintaining good viewing angle will be very hard.

Anyone has a better solution, or knows good packages around?

Another method would be to run an IMAP server on your main mail node
and use a client mail reader from the other boxes.

The latest release of Pine (v3.0.3 from ftp.cac.washington.edu) can use
IMAP and has a nice user interface for mail users - it also supports
MIME which is a *big* plus. There are several IMAP clients for Macs & PCs
so this makes for a good, integrated mail environment with the mail still
being stored on a central machine,

Any chance of getting ahold of such a script as the one mentioned
above, Dave?  I'm still chasing this tiger's tail...

Here's the situation:  Personal Iris 4D/35 running Irix 4.0.1 with no
problems and a serial cable hanging off of serial port 2 going to a
server-jet haning on an HP LaserJet III.  All of our other SGIs can
connect via remote printer connection using the vadmin printer tool
and all of these print, work, and play quite nicely together.  On the
horizon looms CAP6.0, PCNFS, and the modified Clarkson University TCP
package. 'PIPS' is a 'remote printer' set up on pi which looks to
(where else?) pi to print to the local printer 'pips'.  This was a 
kludge in an attempt to get lpr to print something.  I've been changing
the printcap file A LOT, trying different things.

After trying a multitude of things with lpr, here's where I stand:
pi:lpr my.file
pi:lpq

Jul 29 11:09:05 pi lpd[3080]: unknown printer 
Jul 29 11:13:21 pi lpd[3083]: unknown printer 

And my printcap looks (for the moment) like:
lp|pips:\
        :lp=/dev/lp:\
        :af=/usr/adm/lpd-acct:\

Now I know I left out bits of the whole picture.  It's unix, so what do
you want?

ANY creative solutions or kludges welcome.

Thanks in advance.

Of course, to the extent possible.  Bugs will be fixed as much as they
can be fixed and improvements will be made.

Unfortunately, almost all mail failures are caused by operator errors.
Mail works as the machine comes out of the box, especially with the new
"auto-configuring" stuff.  Unfortunately, that configuration is often
either inappropriate for the customer envirornment or is not consistent
with local prejudices on how things should work.

After a few years, if you are not paid to work on the Hotline, you
become very wary about helping people with mail problems in your
"spare" time.  The general problem is hard, and the tools are powerful;
sendmail is "Turing complete."  Solving mail problems is often like
solving a random bug in a customer C or Fortran program, except that

    (1) the customer is generally completely and loudly certain the
	problem is caused by a bug in the "compiler" (sendmail)
	or the rest of the system.
    (2) the language is less than convenient to read and understand.
    (3) the requirements for the program are hard to discover and often
	not understood by the customer, although the customer is often
	loudly certain and wrong.
    (4) the customer is often under great pressure from users with
	even less interest, understanding, or patience, who "just want
	email to work."
