Subject: SCSI tape driver problem
Date: 3 Oct 1994 13:49:26 +0100
I've got an annoying problem with my scsi tape drive.
From other systems like Sun I'm used to put several archives on
one tape by skipping the previously written archives with "mt fsf"
and then writing the next one. When I do this on my linux system
it constantly fails, regardless of which kernel I'm using.
That's the drive specification as it is recognized by the kernel:
Sep 26 19:03:51 catwalk kernel: Configuring Adaptec at IO:330, IRQ 11, DMA priority 5
Sep 26 19:03:51 catwalk kernel: scsi0 : Adaptec 1542

Sep 26 19:03:51 catwalk kernel: Detected scsi tape st0 at scsi0, id 4, lun 0
I'm currently running kernel 1.1.51, tar 1.11.2, st-mt from slackware 2.0.
The device should be ok:
/home/nhk> ls -l /dev/nrmt0
crw-rw-rw- 1 root root 9, 128 Nov 30 1993 /dev/nrmt0
That's what I try to do:
/home/nhk> mt -f /dev/nrmt0 fsf 1
/home/nhk> tar cvf /dev/nrmt0 doom
doom/
doom/doom1.wad
tar: can't write to /dev/nrmt0 : I/O error
/home/nhk>
And that's the debug output if I activate "#define DEBUG" in
/usr/src/linux/drivers/scsi/st.c:

I'm not used to interpreting such messages. Could some wizzard tell me
what's going wrong here and what I could do to append archives to a tape?
btw: The tape is NOT write protected. :-)

Just to mention it. There is InterViews. This is a toolkit
written in C++. It sits on Xlib, not Xt.
It is distributed with the Slackware. Try it!
But beware, it heavily uses floating point arithmetik.
Without FPU you should forget it.
And with X11R6 and GCC2.6.* you can use Fresco. But this kit
isn't ready. It seems to be the followup to InterViews of MIT.
BTW. I am writing on a C++ toolkit. It will not use float arithmetik
(I only have i386 without FPU :-(. The base classes are ready.
They include a base window class with a virtual event dispatching.
If you derive e.g. a button from window, you only have to overload
the event functions, which must have another behavior than in window.
Sorry, no action binding like in Xt. (Is this needed ??).
But it supports resources.
The layout kit works fine. There are hbox, vbox and fbox (fill).
A mbox (matrix, table) must be written.
The inheritance graph looks like this:
colormap
font
gc
dispatcher
drawable ----- pixmap
|
--- window ----- box ----- fbox
| |
| --- hbox
| |
| --- vbox
| |
| --- mbox
| |
| --- toplevel ----- appwindow
| |
| --- popup
|
--- label
|
--- button
It will contain standard widgets like label, button, scroller, ...
The look will be motif like.
But today I have stopped the project, because there is a new
Xlib replacement called Xl written in C++ 3.1.
My toolkit has to wrap Xlib which isn't as good as I think.
If I can port Xl to Linux (or better to gcc), I will build on
top of this library. This will solve the problem of covering
fonts and graphiccontexts and other things.

This may well be the case - but there do exist perfectly sensible
PostScript laser printers which are SCSI-aware. I think some of the
Tektronix Phaser Colour printers are in this category.
So, does a SCSI printer driver exist?

If you use recent client programs and a recent kernel, Linux PPP and
SLIP will send interactive packets before FTP ones. Recent clients
will set the IP TOS (type-of-service) field to favor interactive
traffic, and recent kernels know to send packets with "minimize
latency" TOS before anything else. They even know how to do this
for packets they are routing.
So, if you set up a link with a small MTU, you should get OK performance.

I don't remember the thread, but it is possible that it was before
the kernel did TOS queuing properly. I think that would have been
many months ago, though.

I personally don't see how this can be better than TOS queuing,
without changing the SLIP or PPP protocols. With TOS, an interactive
packet will always go out before any FTP packets that are waiting.
If the interactive traffic wants more bandwidth than is available,
there will be user-visible delays, no matter what your priority
scheme. If it doesn't want more bandwidth than there is, it will
get as much as it asks for, in preference to the bulk traffic.
Actually, I guess there is one thing you could do. You could set
things up so that if an interactive packet gets queued while a bulk
packet is in the middle of transmission, you immediately interrupt
the bulk packet (by sending an end-of-frame character and relying
on the remote end to discard the incomplete frame) and start the
interactive one instead. Ugly, and I don't recommend it for SLIP
(which has no link error detection). It would improve latency
somewhat.
On the other hand, it's fine for people to implement whatever they
want. Whatever floats your boat.

Additional comment:
Your Iceword.org box has *two* IP numbers.
The PPP connection must be 199.86.32.182, the Ethernet card must
be numbered in the 199.199.16 series.
IP numbers are assigned to interfaces, not boxes.
That way, you should be able to talk together on the LAN without problems.

If you mean ethernet adaptors that have 10baseF interfaces, Allied Telesis
has 10baseF versions of their AT1500 (79C960 LANCE) and AT1700 (Fujitsu
MB86965) ethercards.
Transition Engineering also has such boards. Someone from Olicom
reported that they also have them. I'm sure that a number of others
have them, but I don't know off the top of my head.

Subject: 1280x1024, Term, and System Lockup!
Date: 4 Oct 1994 15:18:09 GMT
Hello.
I am running Linux on my 486 DX/2 66 PCI system. I have been running
Term over a 14.4kb modem to dial into work, and was running at 1024x768
resolution.
Everything has been working just honky-dory. No problems whatsoever.
Now, however, I am greedy, and have attempted to alter my Xconfig to run
X at 1280x1024 resolution.
At first, everything was fine. I grabbed one of the examples from the
Sample-Xconfig directory, and my monitor (Nanao F550i) and video card
(ATI Mach32 PCI) were cool with it. I dialed into work with Term, no
problems, and was able to run all but *1* of my X programs with absolutely
no hitches.
This one program, however, causes the whole system to LOCK UP! It draws
the main window fine, and gets as far as bringing the second window up,
but when it attempts to finish drawing it, the system goes dead. The
modem stops sending packets, the disk drive stops, mouse and keyboard
are dead. I have to push the computer's RESET button because I am
completely dead in the water.
The program is "Vantage Spread Sheet", our VHDL simulator.
I tried a new kernel, same problem. I went back to my older 1024x768
resolution, and it all worked fine. Which leads me to believe that
I am not setting up the video correctly, and this is causing some
really unpredictable behavior.
Anyway, here is my video hardware setup:
Nanao F550i 17" monitor
ATI Mach 32 PCI video card (2 Meg RAM)
Xconfig line for 1280x1024 resolution:
"1280x1024" 110 1280 1328 1512 1712 1024 1025 1028 1054
I had also tried this line, but my monitor apparently didn't like it (too
high a refresh rate, I'm assuming):
"1280x1024" 135 1280 1312 1456 1712 1024 1027 1030 1064
Any help would be appreciated. I thank everybody who already responded
to a post of mine for more Xconfig samples, even though they didn't work.
The only other piece of information I can give you is that this is
program comes up with the message "unknown X server XFree86" or something
like that when attempting to bring the program up.
As an aside, I'm kind of surprised my whole system locked up. I really
wouldn't have expected that. I just would have thought Term would die
or something.
Also, I'm still unclear on the concept of the three horizontal and vertical
timing numbers that appear after the pixel value. Is there some mathematical
thing which correlates this to numbers you find in the monitor's Owners Manual?
I still can't figure it out.
Joe
