Thank you Ron for a call for civility.  

Reflecting over all this I think that I do not yet know how to communicate
in the 9fans' language, and that much of the misunderstandings stem from
simple miscommunication.  I'll learn with time, and I hope I will not be to
annoying in the process.  But the couple of times I have seen this kind of
vehemence in the past with other code bases it stemmed from software
systems which had no package management and difficult build/configure
systems.  The end result was that new users would either get discouraged
and drift off, or they would spend literally hundreds of hours to just get
to the point where they can dependably configure, build, and run the code. 
An interesting consequence of this is that any proposed non-trivial change
is met by the old-timers with a resounding "DON'T TOUCH IT!!!"  And there
is good reasons for this -- namely that it took some of these people a year
or more (quite literally) of training and experience to understand how to
maintain the systems.  A significant change will cause them to have to go
back and learn the new system, and they remember what happened the last two
or three times that happened.  I have to wonder if the same this applies to
the Plan 9 community.  If so, the best way to move forward will be to fork
the code.

ethos. n. the characteristic spirit or attitudes of a community,

I think Corey=27s use of the word certainly fit that definition, which I
would hope is what most people heard... whether or not one agrees.

"ack is written purely in Perl, and takes advantage
of the power of Perl's regular expressions."

Forgive my ignorance and irrelevance to this topic,
but what are the advantages of Perl's regular
expressions, over the implementation we have
currently in Plan 9?

I did this @the server
% aux/nfsserver -a tcp!thinktank -c /lib/ndb/nfs
% aux/pcnfsd
% aux/portmapper

@client
# mount -o soft,intr thinktank:thinktank /mnt/nfs
NFS Portmap: RPC: Program not registered

in /sys/log/nfs
thinktank Feb 13 07:07:05 get port
thinktank Feb 13 07:07:32 get port


It seems like I maybe having authentication issue, but not
partifularly sure where to check.
man nfsserver seems to indicate that the client should have a static
ip address is this correct?

the client are using dhcp to configure there ip. I am trying to add
static aliases to clients to see if will work, but wanted to check
everyone else's thought.

So NetApp was basically posturing and ZFS is not fundamental to their
business.  Maybe the publisher would be willing to publish a followup
stating that ZFS is not, and was never, a fundamental part of the product
and that it is only one of something like 50 different file systems.  I get
the feeling that NetApp is afraid of their competitors bring out superior
products.

Anyway, thanks for the info.

Erik's FS does not take NVR from floppy. That's why Erik
suggested that you create a small 9fat partition (using
the Plan 9 Install/Boot CD) on your primary master HDD
and put the NVR on that. I suppose you should also be
able to put the rest of your files in that partition and just
boot directly from that.

Lesson 1: To write predictably fast Haskell -- the kind that competes
with C day in and out
-- use tail recursion, and ensure all types are inferred as simple
machine types, like Int, Word,
Float or Double that simple machine representations. The performance
is there if you want it.

Lesson 2: Laziness has an overhead -- while it allows you to write new
kinds of programs
(where lists may be used as control structures), the memory traffic
that results can be a
penalty if it appears in tight inner loops. Don't rely laziness to
give you performance in your inner loops.

Lesson 3: For heavy optimisation, the C backend to GHC is still the
way to go. Later this
year a new bleeding edge native code generator will be added to GHC,
but until then,
the C backend is still an awesome weapon.

Which of these goals does the current contrib system meet?
Much as I like the contrib system, it still depends on replica, so,
from my point of view, none of the goals are met.
I once saw it take four hours to install openssl. That's just not workable.

Which of these goals does the gui-based contrib system meet?
This is the system that downloads .iso files and then runs replica
against them. It meets 3, to some extent, but is still too slow for
me; it sort of meets 6; but, unfortunately, it fails on 8.

Which of these goals does my extension meet?
2 -- can download/install all of hg, including all dependencies, in 3
minutes, 2 of which are hget
3 -- .1 seconds for 'deps hg'; .1 second for list packages; < .1
second for list installed
4 -- it knows the dependencies and will install everything with one command
5 -- get and install are seperate commands
6 -- ls /installed
8 -- yes -- /installed/<name> is only created when the package is
completely installed (but there are bugs still)
9 -- yes
10. there is little in the way of a db file, just a /installed
directory (which you get by a bind -a)
11. It's far faster than existing systems because it uses hget

1. is obviously not yet met. I think it would be worth doing a tiny 9,
just as we have tinycore, for terminals.
7. is still not met. Package removal is still a mess. I had hoped to
just mount the .iso's and run the tools out of them but have not
figured out all the issues yet. A simple rbind failed to do the trick.

Here are some examples.

# available packages
term% time list
4th
8169
82563
9load-e820
9win
X11
abaco

(etc.)
0.00u 0.00s 0.11r 	 list

# what packages does hg need?
term% time deps hg
z
bz2
openssl
python
0.00u 0.00s 0.10r 	 deps hg

#install tiff
term% install tiff
package is tiff
Package z already installed, no need to do it
9660srv 1151: serving /srv/tiff
FINIS

#install tiff again
term% install tiff
package is tiff
Package z already installed, no need to do it
Package tiff already installed, no need to do it
FINIS
term%

Sources to these tools, including the build script, are at
http://9grid.net/magic/webls?dir=/rminnich/src/package-tools

You can try them out -- it's all there. Packages are in
http://9grid.net/magic/webls?dir=/rminnich/src/package

I don't pretend the scripts are very good, they just represent a
starting point. Experience (mine) is that the system work well. For
example, just doing:

get openssh
install openssh

takes very little time and has worked reliably for me on 9vx.

And, since I installed hg earlier, openssh install skipped the openssh
install step. Left to the reader (or me in a bit): don't download iso
when the package is installed! -- but it's so fast I have not
bothered.

I'm able to install packages now without worrying about whether I will
be ready to disconnect my laptop and go home before the install is
done!

Next step, if this system is found to be useful, is to adapt fgb's gui program.

"4.1 Visualizing trace device output

Once we had the data, we needed a way to analyse the information. After
working with the data for a while, we realized that the output as
shown in Figure
1 would be very useful. No graphiing [sic] tool available to us in
Plan 9 or Linux
was able to create that output. In the end, we determined that gnuplot was the
most appropriate tool, but even then the data required significant processing to
get it into the proper form.

We wrote a suite of scripts usng rc, the plan 9 shell; acid, the Plan
9 debugger;
awk, and sed to generate data appropriate for plotting with gnuplot.
The createplot
script has the ability to filter out functions which ran for less than
a specified number of clock cycles, which is useful for reducing the amount of
noise in a plot. To generate a plot from the data collected earlier, discarding
functions which completed in less than 4000 cycles, we just ran:

    plots/createplot /amd64/9k8pf 4000 ./trace > plotme

and fed the input into gnuplot."

authentication sounds more reasonable to me, p9p together with
something like fuse (even together with the new userspace hackery) or
perhaps a single-user v9fs combined with inferno for doing the

"To return to Knuth=92s paper: everything there---even
input conversion and sorting---is programmed
monolithically and from scratch. In particular the
isolation of words, the handling of punctuation, and
the treatment of case distinctions are built in. Even
if data-filtering programs for these exact purposes
were not at hand, these operations would well be
implemented separately: for separation of concerns,
for easier development, for piecewise debugging, and
for potential reuse. The small gain in efficiency from
integrating them is not likely to warrant the resulting
loss of flexibility. And the worst possible eventuality
eventuality---being forced to combine programs---is
not severe.

The simple pipeline given above will suffice to get
answers right now, not next week or next month. It
could well be enough to finish the job. But even for
a production project, say for the Library of Congress,
it would make a handsome down payment, useful
for testing the value of the answers and for smoking
out follow-on questions."

Forgive my ignorance and irrelevance to this topic,

OS, but I am not able to do so because it lacks the data analysis
tools available in some other systems, like linux.
Because my work involves dealing with data coming from experiments in
astro-particle physics, I am more or less tied to data analysis
software like the R programming language, Python's Numpy, Cern's ROOT
and even gnuplot. While using them, I realized that most of the time I
deal with text files that go here and there as input or output of
small specific programs that perform a given task (I don't know if
this is the result of my Unix/Plan 9 background or just a
coincidence). Say I have a command 'clean' that removes undesired
points from a body of data, and another command 'four' that performs
the FFT; so they are used together as
clean data.txt | four > results.txt
so it occurred to me that one can create single commands to interact
among them to perform some analysis on data, just like in the original
Unix style. Awk can be used as glue among them, with some other small
glue utilities. Plotting data is another thing that I would like to
integrate into this, since plots are quite frequent while analysing
data, but I am not sure how.
Also, something similar to GSL (http://www.gnu.org/software/gsl/)
would be invaluable or maybe even indispensable.
Maybe some day I'll start to write some commands for plan 9 to begin
working on it, but I want to convince myself that this is worth the
time spent.
What do you think of this? my main concern is that perhaps the "do one
thing well" design falls short for data analysis. I've never seen
people work like this on data analysis before (but I do not think I am
the first to do it) because in general, they tend to use large data
analysis frameworks. I'd really appreciate some feedback on this from
people working on data analysis and also from the plan 9 community
(otherwise I wouldn't be writing here :-)

block from a function but you can sort of achieve the same
effect by declaring a global `block variable' and assigning a
block to it -- now you can use this block var elsewhere.

int (^ugly)();

int outer() {
    __block int outer_var = 1;
    ugly = ^{ outer_var = 42; }
}

Presumably __block says outer_var is allocated on heap so now
it can live beyond the life of a particular invocation of
outer().  outer_var will have to be freed when ugly is
assigned to a different block. So it seems GC is a
requirement now.  The original C features were "just right"
to keep the compiler simple and still provide a lot of
expressive power. IMHO GC doesn't fit that model.

Because of the heap allocation, most likely you won't get a
proper closure.  For instance, in Scheme

(define (counter)
  (let ((x 0))
       (lambda () (set! x (+ x 1)) x)))

(define c1 (counter))
(c1) => 1
(c1) => 2
(define c2 (counter))
(c2) => 1
(c1) => 3
etc.

Thus on every invocation of the counter function you get a
fresh counter x and c1 and c2 increment their own copy of x
independently. With blocks you'd render the above as
something like:

typedef int(^ctr_t)();

int counter(ctr_t*c) {
	__block int x = 0;
	*c = ^{ return ++x; }
}

ctr_t c1, c2;

void foo()
{
	counter(&c1);	// presumably taking address of a block var is allowed
	printf("%d\n", c1());
	printf("%d\n", c1());
	counter(&c2);
	printf("%d\n", c2());
	printf("%d\n", c1());
}

I bet you'd get 1 2 3 4, and not 1 2 1 3. If they do get this
right, they'd have to allocate a fresh x on every invocation
of counter and this will add to the memory garbage. Now their
GC problem is even worse!  And I haven't even used
concurrency so far!

They very carefully delineate what you can and can not do
with lexically scoped variables etc. but the model is far
more complex.

Amen! Or kill one's prejudice against parens (talk to your

have thousands.  we're currently operating without auth (in part due
to configuration issues), so I don't know how well it will scale.  The
other aspect here is that in current configurations, every "run" has a
different machine configuration based on what you request from the job
scheduler and what you actually get.  We pretty much get different IP
addresses every time, with different front ends, different file
servers, etc. etc.
Again though - the idea is to use file systems more pervasively within
the applications as well -- so there may be multiple file servers per
node providing different services depending on workload needs at the
particular point of computation.  Read our MTAGS paper from last
year's supercomputing conference to get a bigger picture view on how
we view services coming, going, migrating, and adapting to changing
application usage and failure.

Why Desktop Multiprocessing Has Speed Limits
Computerworld (10/05/09) Vol. 43, No. 30, P. 24; Wood, Lamont

Despite the mainstreaming of multicore processors for desktops, not
every desktop application can be rewritten for multicore frameworks,
which means some bottlenecks will persist.  "If you have a task that
cannot be parallelized and you are currently on a plateau of
performance in a single-processor environment, you will not see that
task getting significantly faster in the future," says analyst Tom
Halfhill.  Adobe Systems' Russell Williams points out that performance
does not scale linearly even with parallelization on account of memory
bandwidth issues and delays dictated by interprocessor communications.
Analyst Jim Turley says that, overall, consumer operating systems
"don't do anything smart" with multicore architecture.  "We have to
reinvent computing, and get away from the fundamental premises we
inherited from von Neumann," says Microsoft technical fellow Burton
Smith.  "He assumed one instruction would be executed at a time, and
we are no longer even maintaining the appearance of one instruction at
a time." Analyst Rob Enderle notes that most applications will operate
on only a single core, which means that the benefits of a multicore
architecture only come when multiple applications are run.  "What we'd
all like is a magic compiler that takes yesterday's source code and
spreads it across multiple cores, and that is just not happening,"
says Turley.  Despite the performance issues, vendors prefer multicore
processors because they can facilitate a higher level of power
efficiency.  "Using multiple cores will let us get more performance
while staying within the power envelope," says Acer's Glenn Jystad.

What is the canonical way for added ("opt", "pkg" ?) stuff. Letting

More generally, what is the policy for add-ons? Providing rc(1)
fragments to bind the added stuff?

information.  It can implement the traditional user-group-world
permissions.  It can implement access control lists.  It can do
a user name translation and say that Bob will always get Alice's
priviliges.  It can do anything it wants, because it's handling
the open request and will either succeed it for fail it and the
client reacts accordingly.

Another thing to note is that every file server can have a different
set of users and groups.  Your fossil file system has one set
of users and groups you've defined.  When you do a 9fs sources,
you attach to another file server with a completely different
set.  In fact, there's no requirement that the intersection of
the sets be non-empty.

Finally, if we try to make the in-kernel file servers borrow
another file server's user/group list, there are some annoying
complications.  If I have several file servers, which user list
do I use?  The first thought would be to have it know about
/adm/users, but each process might have a different, or no,
/adm/users in its name space.  Plus, there's a chicken and
egg problem.  The server which gives you /dev/sd00/nvram
has to approve of the attach when fossil wants to open its
/dev/sd00/fossil, but until fossil has opened it, there's no
way of knowing what's in /adm/users on that particular fossil.

So for in-kernel file servers, it's best to look at them as hostowner
and world and forget about groups.  For lib9p based servers,
you can link in a different implementation of hasperm() and
get whatever permissions checking you want, but the default
behavior is to assume that the named group has exactly one
member: the group leader.

"What compiler technology is used to build the compilers?

Gccgo has a C++ front-end with a recursive descent parser coupled to
the standard GCC back end. Gc is written in C using yacc/bison for the
parser. Although it's a new program, it fits in the Plan 9 C compiler
suite (http://plan9.bell-labs.com/sys/doc/compiler.html) and uses a
variant of the Plan 9 loader to generate ELF binaries."

So I believe it could be ported...
As for a comparison to limbo, I think someone who knows more about
limbo would be better qualified to delve into the language, but for
one thing it isn't tied to Inferno, and compiles natively, as opposed
to dis.
(it also has some limited type inference)

1) All "contrib" packages write in /$objtype/bin, /rc/bin and /sys/man 
(or /man, see 3).

2) It's up the user to "bind -c" in /$objtype/bin, /rc/bin and 
/sys/man so that written files end where he wants. Depending on who
installs, so depending on the namespace, all flavors can be achieved
(system wide or individual).

3) Shouldn't /man and /rc/bin be, as /bin, "empty unwritable directories,
place holders", with an initial bind(1) (without "-c"; probably
$objtype agnostic either, since almost all programs are supposed to
exist in an $objtype flavor for man, and should not be a concern for rc)
of /sys/man and (new) /sys/rc/bin there?

Note: in this scheme /rc/bin is more a mean (an undirection) so that rc
programs end in the correct place than something usefull at use time,
since it ends probably bind'ed in /bin.

I started implementing IPv6 and got deflected doing other stuff.  The
IP stack in the upcoming release is still IPv4 but the interface to
user programs uses IPv6 addresses (with the embedded IPv4 format for
v4 addresses).  It's kind of odd without a v6 stack, but I was hoping
to get back to the v6 implementation and wanted to make sure I didn't
have to go and change all the user level code again.

I'm also a linux user, and unfortunately not so young,
however, I expect Plan 9 something different from those
free unicies.  I don't care how much the Plan 9 is
different from those of today, rather I prefer it,
if it's neccessary from technical view point.

[Elliott]

i think you misattribute the reluctance amongst the youth of your acquaintance to
use Plan 9. i admit there were lots of people who gave up when typing 'vi' didn't
do what they expected, and when they found out that there wasn't anything like pine
and no way to 'talk'. but those were the sort of people 99% of whose computer use
consists of 'pine' and 'talk'. they're also smack-bang in the centre of the MS
target market, so we may as well forget about them.

there was more interest amongst the more technically inclined (though some of them
are damn hard to wean off vi) but as soon as they found that (a) they'd have to pay
to get the source and (b) they couldn't give away their work that was based on Plan 9,
they tended to lose interest. i know that i couldn't afford Plan 9 while i was a
student: it was only after i'd got a job that i forked out for it. i doubt very much
that if i hadn't been at your university, i'd have heard of Plan 9, let alone read
the papers and then bought it.

as long as FSF/Linux/FreeBSD stuff is free, and MS stuff is effectively free, i don't
think being better or more interesting or whatever helps one jot. the youth of today,
for whom i presume to speak, guessing that i'm the youngest 9fan, expects their
software to be free and to come with complete source, should they choose to hack
around with it. they also expect full (and fast) access to changes and the like: not
to be sat around wondering if they'll ever see Brazil.

and then there's the catch-22: the enticement of having users. no-one likes to write
software to push it to the back of their disc to rot (though i do wonder sometimes),
and the one place where you can be sure of users is the free world. if you can't
give your code away for free to run on a free platform, you're going to have fewer
users than if you could. and those users are less likely to be members of your
peer-group, because they, as we know, are all messing about writing emacs macros
and versions of tetris to run on VT100's.

but given that neither Plan 9 nor Brazil will be free, we may as well give up
complaining and be happy that we've seen the light. mind you, the question here
seems to be "will we see the second coming", which is rather appropriate at the
moment.

maybe when the religious nutcases run round killing each other, Plan 9/Brazil will
have its day, like the mammals that had to wait until the dinosaurs were out of
the way before they could come out of their holes and grow to respectable sizes?

I don't think this code makes any assumptions
about the Runes.  It just translates incoming
latin1 text into utf.

> Are there any special purpose to use this coding?

I wrote mothra, and worked on it until I left Bell
Labs two years ago.

I just assumed that since the html standard specifies
that the character set is latin1, I ought to convert
latin1 to utf on input.  Obviously if you prefer to
read JIS, you can change latin2utf appropriately.

Not that I have any real definitive answer, but I can hazard a guess...

A lot of content on the Internet is in Latin1 instead of UTF,
especially at the time mothra was written.

I'm thinking that at the time of the CD distribution (April 1995)
most web servers didn't include character set info in the HTTP
headers, so Latin1 probably seemed like a good default.

You could probably extend the part of mothra that cracks the
headers so that it recognizes the encoding line in the HTTP headers
(Content-Transfer-Encoding: or something similar, I think) and
acts accordingly, probably by pushing it thru tcs.

[okamoto]

I asked a few days ago why mothra does not show Japanese text.  After that many negative answers were returned.  Yes, I know I'd better to choose another Web browser.  However, we have no choise than mothra, if we confined ourselves to Plan 9.
Furthermore, if she(Hah?) could display Japanmese, I can use it as an tool to introduce basic usage of Plan 9 system to my users.

Then, I'm still hanging on that problem.

When I see the codes in rdhtml.c, I found that
the latin2utf() assumes the runes are latines, not
more large, say three byte utfs such as Japanese.

For examples,
  for(l=latin;*l;l++) nutf+=runelen(*l&255);  etc.

Are there any special purpose to use this coding?

a slightly more elegant way is to just always do challenge
response, and fire up netkey when you want to use a password.

having su accept a password encourages people to type their
passwords over the network.  if netkey is the only thing
that accepts passwords (aside from the boot process), then
you only have to worry about training users not to run netkey
remotely.

i've been using the following for quite a while.  i think
it's a cross between something i wrote and something tom killian wrote.

it accepts a -n option to say don't reinitialize the namespace,
and a -c option to specify a command to run instead of a shell.

#include <u.h>
#include <libc.h>
#include <auth.h>

int	debug;
Chalstate chal;
char	response[NETCHLEN];

you can get a Unix version of mk from the Inferno download, provided
your Unix is one that you can get Inferno for. alternatively you could

OK, so what's the secret?  Somewhere in my configuration of a CPU and 
authentication server, I have managed to screw up.  Now how do I 
persuade the auth server not to look for itself on the network so it 
can grant itself access to the fileserver?

It eventually gives up and uses its own password, but I dislike waiting 
for it to time out first.  This is not the way "things are meant to be" 
but I can't figure out what it is that I need to change.

Please can some kind soul point me to the right place (the NET db?  I 
don't think I've broken anything in there - the KEY file, how do I 
remove the AUTH portion of it, without destroying it completely?  what 
is the real address for a dummy auth 0.0.0.1, 0.0.1.0?  I have 
conflicting values in various places :-(

Thanks a lot, everyone.

Hello 9fans!

A patch to 8.5 window is posted to:
ftp://plan9.aichi-u.ac.jp/9win.bod

This patch enables the grab.

Grab enables to copy the image in rectangle of screen.
The output is created in /tmp with the name grab.3c.
You can see the result by: fb/9v /tmp/grab.3c

Click right mouse button, then you will see new menu item "Grab".
Select Grab then button operations are as follows:
Left button determines the rectangle to cut.
Middle button and rifht button work the same;
they show menu: OK, Redo, Abort

There is a philisophical problem with battery backup Cache, that is for sure.
DPT (internally) has a Battery Backed up PM3334 card, but none of our OEMs
want it ...

Sync (command 35 in the SCSI command set) flushes cache on both the card and
the drives. This is the command that is issued by our other drivers to ensure
clean shutdowns, critical data paths and just before a SCSI bus reset.

As for the Battery Backup issue, one will need to ensure that there is
continuous power to the drives as well since their sense of Cache also
gets lost during power outages and SCSI Bus resets. The consensus is that
since the drives have their own problems with Cache, that a UPS is a far
better investment than YABRS (Yet Another Battery Replacement Schedule) for
the server market we generally target our controllers for.

The Battery backup card, if ever released, will be in the higher end PCI
or I2O product lines.

Disclaimer: This is my opinion and does not reflect DPT's opinion.

>>All the above DPT PCI cards do circles around the 154X series of cards. In

> I'm interested.  Is the PM2041W a ISA/DMA busmaster?

Yes, suffering from the same ills as all ISA cards, the 16MB limit. John did
not set up any bounce buffer technology in his driver, once that is done if
the system has more than 16MB of memory, forcing the address, to lets say 01F0,
will work.

Your mileage will vary, as my comparison was a direct result of the BSDi
BSD/OS 2.1 driver.

> How many can I put in one machine (i.e. which DMA channels and IRQ's
> does is support)?  What is the DMA transfer speed?

DPT ISA cards can be placed at 01F0, 0170, 0230 and 0330. However, they only
have three possible interrupts (12, 14 and 15) limiting you to three ISA
cards in a system (some motherboards allow for ISA interrupt sharing through
a wired-or gating of the interrupt lines).

> I will try to get a technical reference manual on the PM2041W,
> and if successfull, I will give the controller a try.

Shhhh, you may wish to indicate that you intend to evaluate the card and
be modifying a driver to run with this card and that your evaluation will be
posted on the worldwide plan 9 discussion list ...

Sincerely -- Mark Salyzyn

first of all, the Irix version of alef isn't a port; it is cross-built
from plan 9.  that is, i use the plan 9 compilers and loaders to produce
an Irix executable.

that said, "porting" the compiler and loader is the easy part.  since the
compiler and loader generate plan 9-style symbol tables, the debugger on the
target system probably won't understand the resulting executable.
you'll also have to bring along acid and some other utilities, like ar.
to get acid, you need to emulate the portion of libmach for
the target architecture and figure out how to map the plan 9 process
control model to that of the target system.  i had access to the Irix
source when i didit, so although i couldn't modify the operating system,
i was able to find enough rocks to hide process state under.  even then, the Irix
version of acid lacks some of the functionality of the plan 9 version.

of course, if you don't need a debugger for your alef programs, it should
be relatively easy to build the alef compiler and run-time library; mainly
you need to understand the target system's system call conventions and
multi-threading package.  the latter will have to be ported to plan 9.

if you want to truly port the alef compiler, then i can't be of much help
because we haven't done it yet.

what about the plan9 terminal emulator for Windows 95/NT? is it

For those of you that use Sam on Windows 95/NT:
There is a new version which can be installed by running
the self extracting executable available thru netlib.

Go to
	http://netlib.bell-labs.com/netlib/research
and select the file sam.exe, or more directly,
	http://netlib.bell-labs.com/netlib/research/sam.exe

Major changes from the previous release include:
*) The commands that run external programs now work, i.e. '<', '>', '|', '!'.
   Included with the distribution are several command line programs
   that are useful with sam, such as: pwd, echo, fmt, and sort.
*) There is a 'B' command that enables sam to receive file open requests
   from other programs.

Let me know any problems you have.

That doesn't achieve the same effect, because it doesn't invoke
the VESA power saving mode.  Modern monitors watch the HSYNC and
VSYNC signals; if one stops they blank the screen in a moderate
power saving mode, and if both stop the monitor goes to very low
power mode.

Here are some suggested changes to devvga to attempt to support screen
blanking, in the style of XFree86 3.3.  (Doing this completely right
requires chipset specific code, and more extensive changes.)  The
generic vga mechanisms could probably be used via aux/vga, but
/dev/vgactl is such a nice interface that I couldn't resist using it.
(Is that the wrong approach?)

8c allocates memory and doesnt free it when unused. 8l doesn't.
almost all of the allocated memory in 8l is used in a linked
list of instructions. i doubt if you will save any space by
calling malloc and free.

if there is any space to be had, it is from rearranging the
structures Adr and Prog (which contains 2 Adr's) to be
more specific to individual instruction types. (ie most
instructions have only one full address with the other
address a register.)

here's an unofficial answer.
 
we've been working on other things for the past year or so,
so there has been little new work on brazil.  phil and rob
and dave say that they want to get back to working on
brazil, but we don't know when that will be.

our plan 9 system is only used to access the old worm for archival
purposes.  our new file server contains only the brazil source
tree, so brazil is our current development system.  brazil is not
in a state that is releasable, so i doubt that there will be
a brazil release in the foreseeable future.

of course, all of this could change in a wink.

Russ Cox made it easier to add new keyboard sequences to
plan 9.  The pertinent files are:

ftp://plan9.bell-labs.com/plan9/update/cmd/aux/mklatinkbd.c
frp://plan9.bell-labs.com/plan9/update/9/port/858968110.rc

Here's his mail explaining it:

  Subject: /lib/keyboard and latin1.c

  A while ago, Rob and I exchanged the attached email.
  It's a shame that editing /lib/keyboard doesn't work, so
  I fixed that.  Take a look at ls /usr/rsc/kbd/mklatinkbd.c.
  The way I've installed it at home is to change latin1.c to read

	struct cvlist
	{
		char	*ld;		/* must be seen before using this conversion */
		char	*si;		/* options for last input characters */
		Rune	*so;		/* the corresponding Rune for each si entry */
	} latintab[] = {
	#include "latin1.h"
		0,	0,		0
	};

  and then have mkfile generate latin1.h with 
	aux/mklatinkbd /lib/keyboard >latin1.h

  As an aside, I found two ``bugs'' in the keyboard file
  as shipped on the CD.  The sequences <= and => are used
  for both ≤, ≥ and ⇐,⇒, according to /lib/keyboard.
  It looks like they've been fixed, at least on emelie
  (haven't checked elsewhere).  The program will catch
  duplicate sequences.

    From rsc Fri Oct 25 08:36:01 1996
    Subject: re: /lib/keyboard

    how does one add more compose sequences
    in plan 9?  i tried editing /lib/keyboard
    and rebooting, but that did not work.

      From rob Fri Oct 25 09:02:01 1996
      Subject: re: /lib/keyboard

      unfortunately, it's not nearly that easy.  you need to edit
      /n/bootes/sys/src/9/port/latin1.c.  you just edited the
      documentation, a rarely successful method of change.

I noticed today that latex gets an fp exception on the following input
(derived from a much more interesting document, of course):

\documentstyle{article}
\begin{document}
Troff!
\filbreak
\eject
\end{document}

On an x86, the fault says:
  14097: math coprocessor	vlistout+0x49f	MOVBZX	0x5(AX),AX
which acid reports as:
  At pc:0x0001a9e6:vlistout+0x49f /sys/src/cmd/tex/web2c/tex/tex4.c:937
On a sparc the fault is reported as happening in the preceeding call to [z]round().

So, before I plunge into debugging this, has anyone already fixed it?

I found a bug in lpdaemon.c ...
When if-defed for Plan9, the TMPDIR is defined as follows: 

	#define TMPDIR "/sys/lib/lp/tmp"

In the function 'tempfile()' an array is defined as:
	char tmpf[20];	
and later used in:
	sprintf(tmpf, "%s/lp%d.%d", TMPDIR, getpid(), tindx++);

The resulting string overruns the 'tmpf' buffer - it really 
needs to be at least 32 bytes.

We're running our web sites (plan9.bell-labs.com and
inferno.lucent.com) on Brazil, the internal version of
Plan 9.  Sean Dorward wrote the code here.  We haven't
done anything that shouldn't run on the released version.
We should be able to give you the current versions of
the http daemon, dns, and mailer if you have a plan 9 license.

We don't have disk quota's, ken just yells at anyone that
hogs the jukebox.  You'll have to change the file system
to support them.  Alternately, you could have
a daemon that sweeps the system enforcing after the fact
or hire ken.

Both of our servers are PC's.  The more active is a 60 MHZ
pentium.  It averages about 10000 hits a day without a noticable
load.  I have no idea what it takes to support 2000 users.

What would you need for mail?  We don't support POP3 though it'ld
be trivial to give the mailer a POP3 interface, i.e., it's not that
different than the interactive one.

Ncube has had problems with the fact that proc.c requires all
Rendez structures to not be reallocatable, i.e., they can't
exist on stacks or in objects that are freed.  If anyone cares,
I have a rewrite of sleep/wakeup that gets around that.
The shipped kernel should be clean this way so that it shouldn't
be a problem to anyone that hasn't been hacking hard.

They also found a neat bug in pexit().  Move the unlock on line
691 to after the wakeup.  Otherwise you can blow up indirecting
through a null reference.

			p->nwait++;
			unlock(&p->exl);

			wakeup(&p->waitr);

goes to

			p->nwait++;

			wakeup(&p->waitr);
			unlock(&p->exl);

One more ape bug...  A common unix idiom is bind followed by listen.
In ape, bind sets the socket's port, and but listen also tries to do
that.  To avoid an error in that case, I propose listen.c:139 be
modified as follows:

		if(lip->sin_port >= 0) {
			if (write(cfd, "bind 0", 6) < 0) {
				errno = EGREG;
				close(cfd);
				return -1;
			}
			sprintf(msg, "announce %d", ntohs(lip->sin_port));

Another ape bug: putenv doesn't really do that.
(/n/lucent/sys/src/ape/lib/bsd/putenv.c)
It looks like the code in putenv.c was intended to
create a new file in /env, but skipped the /env
part.  But, given the code for execve, that's not
correct either.  Dropping in the BSD putenv will
probably fix the bug with a minimum of typing.

I've noticed that APE has some byte order problems in the bsd compatability
code. The bsd interface uses network order exclusively, while the ape code
sometimes assumed host order. There have already been some updates on
this topic: enclosed are a few additional changes.

One problem that isn't fixed is that gethostbyaddr calls gethostbyname
with the ascii dotted-quad form of the network address.  That's a good
idea, except that the connection server only asks dns to return ip
addresses, even though it returns the whole record if it came from ndb.
gethostbyname could be modified to get the answer, but I think cs is
a more appropriate place for it.

last week i posted a `fix' to 8c to handle side-effects in an lvalue receiving
a structure literal.  at the time, i wasn't able to try it in the other compilers,
but discovered yesterday that because something is missing from side(), the fix
isn't optimal on the 386 or 68020.  worse, because it invokes code containing
an existing but rarely seen error in cgen.c,
the `fix' will also break common cases of structure literals as arguments in
any compiler where REGARG is non-zero and equal to REGRET
(that includes most of the RISC compilers).  i've got a correct repair
that i'll post shortly.

2. And the ethernet card swaped...

Well, we have found that many (all?) Dell machines think that the CMOS
can never report more than 16MB, so it doesn't, even if you have more
than 16MB of memory.  Then there are machines which we can't accurately
probe for how much memory there is, but the CMOS is right!  There are
also weird caching affect (i.e. you can read/write memory beyond the
end of memory as long as it stays in cache) as well as new and unique
ways to remap addresses that are beyond the end of memory.  To give you
and idea, here are the various parameters one can set in their boot.default
file for BSD/OS:

	-basemen mem	Assume this much base memory (memory below 1M)
	-cmosmem	Limit memory search to the mount given by the CMOS
	-extended mem	Limit the amount of memory to check
	-memsize mem	Just assume this it the amount of memory
	-noflushcache	Don't flush the cache while sizing memory

Each one of these is needed for at least one machine that we have had
problems with.  I should note that we can probe the proper amount of
memory on *most* machines, but...

Finding out how much memory you have is certainly a black art.

 1. Where is the equivalent of the "rc" files... i.e. where do I put
 stuff so that things like "listen" get run automatically when the machine
 boots.

/rc/bin/termrc for terminals
/rc/bin/cpurc for cpu servers

 2. I set up dns by running ndb/dns - this seemed to give me some 
 form of nameservice.  If I understand the manuals correctly, this starts
 up a domain name server on the machine.   Is there an equivalent to 
 the /etc/resolv.conf idea of just specifying a domain server without
 running a local name server?  BTW, the way the nameserver is running
 currently it only seems to resolve fully qualified names...I presume
 this is because it doesn't know what domain it is in... 
 cat /dev/hostdomain produces nothing... how do I tell it what domain it
 is in?  presumeably its in /lib/ndb/local. 

We only use fully qualified names.  Sorry.

We never did a separate resolver.

2. I set up dns by running ndb/dns - this seemed to give me some 
form of nameservice.  If I understand the manuals correctly, this starts
up a domain name server on the machine.   Is there an equivalent to 
the /etc/resolv.conf idea of just specifying a domain server without
running a local name server?  BTW, the way the nameserver is running
currently it only seems to resolve fully qualified names...I presume
this is because it doesn't know what domain it is in... 
cat /dev/hostdomain produces nothing... how do I tell it what domain it
is in?  presumeably its in /lib/ndb/local. 
 

3. How do I "disable anonymous access"... The FAQ points to the -N
option in aux/telnetd... but where does one specify this -N?  (I just
answered this myself -despite the FAQ being vague... in /bin/service)

4. Who maintains the FAQ?

Thanks. What had me fooled about the C/1996 B2 (Hyakutake) elements is
that the eccentricity has been listed as 1.0000. According to the
latest (this morning) it really is 1.0000 (to be exact, 1.000019). I
have never seen an element like this before and figured it *had* to be
a misprint.
   Expect (later this evening?) a new replacement comet.c file at
ftp.stratcom.com in directory /pub/stratcom/comet
Thanks again,

That's cool.  But you seem to have sent the message to 9fans, which is a 
mailing list for users of plan 9.  Further, your email return address looks 
rather bogus, hence I'm sending this back to the 9fans list in hopes that you 
will get it.

According to the plan9 web page at http://plan9.att.com/plan9/distrib.html, 
"Read the shrinkwrap license to determine whether its terms are acceptable to 
you. The major restriction is that you can't sell products or services based 
on the supplied software. However, AT&T Software Solutions Group will 
negotiate commercial licenses (telephone 800 462 8146 or 1 415 943 4076)."

So my advice is to try calling AT&T Software Solutions Group directly.

The infamous 'no newline at end of file' problem. Boddle doesn't complain
about input files with no newline on the end, but the extraction by ed appends
one and so the checksums differ. I've put the correct checksum into the file
fs/pc/813525539.rc. There's probablt no need for you to pull it over again,
the pc.c you have created is likely correct.

Here are the two basic questions I have before I go spend money on plan9.
(Well, ok, so I know I'm going to spend money, I just don't know if I
can do it now, or will have to wait a couple of months.)

Here goes:

1. Does plan9 run on DecStation 2100s?  DecStation 2100s are little endian
  machines on a mips chip.   I've read the docs and it says there is
  only support for big endian machines.  Is this the truth and gospel or
  out of date docs?

2. Is it possible to run plan9 on a single standalone PC?  (I'd be willing
   to take the performance hit to get it up and running - 
   (I would be thinking of getting it up and running so that I could 
    get it to run on some of my other machines.)  Obviously the strength
    of plan9 is its network capability - the hump I'm faced with is
    the hump of getting it up and running without totally wrecking
    all the other little beasties in my apartment. 
    (if it were possible, I'd go buy a brand spanking new PC to run
       the thing on.)

no, an authentication server isn't needed (or used) by u9fs in the distribution.
on plan 9,

i suspect that the user name that appears isn't registered on the unix server.
especially so if the name is `none'.

Subject: re: breakup

A partial answer to "how will this affect AT&T Bell Labs?"
is as follows--the new, still unnamed technology company
will get the bulk of core Bell Labs, which includes research,
as well as the Bell Labs name.  The exact fraction is
not decided yet but numbers in the range 60-80% have
been mentioned.  The remainder will stay with AT&T
in a new AT&T Laboratories.  In thinking about these
figures, keep in mind that about half of research is
in the physical science area and it is assumed that
essentially all of this will be in Bell Labs; that
biases the division of the rest.

In general the division will be along obvious lines of work--
people involved with services to AT&T, with products to
Bell Labs.  In some cases, including most of our own
group, it is not an obvious call, and we don't know
which it will be.  Arno Penzias did remark today that the
split will not be like the one at divestiture,
in which one or two people from each group were selected
to go to Bellcore to yield similar populations; here it will
be more in groups as a whole. (But Arno is about to
leave his position as VP of research, so this is only
his opinion.)

Incidentally the intended time scale has the
new internal organizations being planned during the
fall and in place in the spring.  The formal
split is supposed to be accomplished at the beginning
of 1997.

I don't know what will happen with Plan 9 licensing.
During the official briefing it was mentioned that
division of IP was one of the thorniest of all the
issues, but this has to do especially with patent
licencing (if AT&T has an agreement with someone now,
who inherits it?)  Given that Plan 9 is hardly of
strategic interest to either company, I would trust
that we could argue that the outside licensing should
go where we go, and I wouldn't be surprised if
the other company kept rights to use.

There's no reason at this point to expect the split
to change the nature of our work.  But a lot is going
to happen in the next year.

says 16450 but we typically use 16552's.  The code will turn
on the fifo's if you turn on modem flow control
(e.g. echo m > /dev/eia0ctl).  You can make it the default
if you want, but that screws up serial mice.

Arrange using the usual Sun mechanisms to boot file 9sscd,
not 9sscpu.  This is a kernel configured as a terminal using a
CD-ROM as its root.  Boot that file, and when it asks you for
the root file system, say
	#R6/cd6
if your CD-ROM is SCSI unit 6.  Follow your nose after that.
Of course you will be unable to use the root as a writable file
system, but you can start kfs, use ipconfig to start networking,
and so on.  Read the manuals.

>From some guy

Hi,

I'd like to ask you a question about Plan9 installation procedure.

I have an un-networked Sparc IPX machine, running SunOS4.1.3, which I am 
trying to configure with the Plan9 OS and I am having some difficulty 
understanding the documented Sparc install procedure. I have a CDROM attached 
to the machines SCSI port and am able to mount the cdrom drive, but i do
not understand how to boot the Plan9 code. Do I copy the 9sscpu file to
root (/) and link to vmunix, then perform: STOP-a >boot? I've tried most of
the URLs and have not found the specific information.

I would appreciate if you can help me...re-direct me.

thank  you for your time.

I trawled through the offerings at CompUSA a few weeks ago and found the Trio64
on the STB Powergraph 64 and some Number9 card I can't remember the number of
(perhaps Motion 330?) as well as the Diamond Stealth 64 DRAM. I think the Hercules
Terminator 64 DRAM also uses it. In any case, the chip used was clearly marked
on all the boxes I looked at.

Remember from the updated aux/vga CHANGES file:

	09-Aug-95
	=========
	1) data.c mkfile trio64.c (new) vga.h /lib/vgadb
	   Support for Trio32/Trio64.
	   There's a bug at high resolutions causing a thin white stripe to appear between
	   the right edge of the display and the border.

I'll be trying to fix this when I can get time on the systems we have with the Trio64,
they're all heavily used in Ken's house right now ('high reolution' means > 1024).

Subjectively, the Tseng Labs ET4000/W32p gives the best performance under
Plan 9, its only drawbacks being the lack of a hardware cursor in 2x8bit mode
and a maximum pixel-clock of 135MHz when used with a suitable RAMDAC.
The Hercules Stingray 64/Video with the ARK2000pv chip looks good too and
doesn't have restrictions on the use of the hardware cursor. Unfortunately we
have't been able to get the hardware cursor to work satisfactorily under Plan 9.
Don't know why, haven't had time to investigate.

As advised by 9fans, we've replaced the online distribution with
one containing some of the more important fixes, i.e., those that
allow more sites to install plan 9. disk1 and disk2.vd are new and
contain:
- the floppy DMA overrun fixes
- changes to devata.c to put up with disks returning bogus ident
information
- the current disk/prep
- the current aux/vga and /lib/vgadb.

It's tested to the extent that I tried what I had the hardware to try.
Please tell me if anyone has problems.

The old versions are still out there under the names disk1.orig
and disk{2,3,4}.vd.orig.

Unlike dossrv, ftpfs doesn't post a file in /srv.  Dossrv does that
since it can be mounted many times.  If you removed dossrv's /srv/dos
file, it too would go away since that would clunk the last reference.

That sounds like a bug.  But why doesn't ftpfs suffer the same

When you open a window, a new name space is created with the window's
files bound in the appropriate places, i.e. /dev and /mnt/8½.  These
binds are in effect open file descriptors and the window will not
go away until they are closed.  This is why the command line
	sleep 10 >[0]/tmp/zz >[1]/tmp/zz >[2]/tmp/zz >[3]/tmp/zz &
stops the window from closing.

The namespace itself is referenced counted, so when all processes associated
with the name space have exited, any open files bound in the namespace are closed.

The reason the window closes even though ftpfs is running is rather subtle.
When ftpfs is started, it rforks the server process with the flag RFNAMEG
set.  This puts the server process in a copy of the original namespace.
Note that since it is a copy of the original namespace, it contains
references the the window's files.
The server is accessed by a pipe that is mounted in the original namespace.
When /bin/rc exits, the original namespace closes.  At this point, the window
is held up by ftpfs's namespace.  However, the original name-space contains
the only reference to one end of the pipe to ftpfs, thus this end of
the pipe is closed.  Ftpfs notices this and dies.  This closes
the namespace associated with ftpfs, closing the files associated with the window,
which finally allows the window to close.......

The reason that the above does not occur for dossrv is that the server
process is not rforked with RFNAMEG set.  This is probably a bug.  The net
result is that rc and dossrv share the same namespace, and thus when rc exits,
the namespace is not closed and hence dossrv does not die.....In effect
dossrv holds itself up, which stops the window from closing.

In response to the questions I posted I've gotten answers via private
email.  Thanks to Jim and Dave for their help!

I was going to post a summary once things were stablized a bit, but
here's a quick rundown:

My ss2 didn't like the new scsi driver.  Replacing src/fs/ss/scsi.c
with the code from the first edition fixed the disk problems I was
seeing.

Also, the ss fs gets the clock wrong.  In toy.c, I fixed it by
incrementing rtc.year by 68 after reading the clock.  After doing that,
I noticed that the terminal version of the kernel fixes this problem
slightly differently, but I haven't tried making that change to the
fileserver yet.

On a (sparc, at least) auth server, boot dies if you tell it that its
ip address is 0.0.0.0; use the real ip number instead.

Here at Basser we have a mixture of machines running the old
and new versions of Plan 9.  We would like to get rid of the old
version.  However, one of these machines is a fileserver, with
attached jukebox, containing valuable files.  Is it safe to just install
a new file server kernel on it?  I am guessing that the disk filesystem
format hasn't changed; is this a safe assumption to make?

Note for those not in the know: the 9P protocol has changed in the
second edition, due to changes in the way that Plan 9 does its
authentication.  Writing a "protocol convertor" looks infeasible,
unless you only want to log in as user "none".  Not all files on the old
system are publically readable, and neither should they be.  Currently
we have one CPU server still on the old system, allowing us to use ftpfs
to access the old files.  But this is quite clumsy, hence my desire
to just run the new system with the old files.

So...  Can it be done?

I'm one of the several.  I actually have the new system running on 3/50s
and 3/60s.  At some stage I will tidy this up and make it available to
anyone who cares (and has a valid license).

I also have 80% of a port of Plan 9 to the DEC Alpha architecture.  Currently
only axp 400s and 500s.  I plan to make this available when I reach 85% :-)
I'm hoping that someone out there who has a spare alpha will help to finish it off.

Since both of these ports are derived from Plan 9, I am only allowed to give
them to other licencees.  This will mean checking with AT&T that you
actually have a licence.

Please note that I am not quite ready to distribute the alpha port -- preparing
the distribution will take time, which I am short of at the moment.  I am telling
you all this to try to avoid duplication of effort.  I'll announce to the list when
it's ready -- hopefully within a month.

I just installed the second edition on a sparcstation 2 (fs) and some
slcs (cpu and term), using essentially the procedure for installing the
first edition (no pc required).  One problem I see is that the file
server complains about bad udp checksums, "scsiintr: not disconnect:
status 87 step/intr=418 dma=94000011", status errors from D6.0.1.0 and
D6.0.3.0, and check reporting various problems.  Has anyone else seen
this, or has my old hardware finally gone bad?

Rather than have everyone dig thru the majordumbo archives, I'll just

Also, could everyone please check that their addresses are correct 
and not duplicated or otherwise confused?

         AT&T ANNOUNCES *** AT&T today announced that Plan 9, a new 
         computer operating system from AT&T Bell Laboratories, is now 
         available for research and educational use.  The Plan 9 operating 
         system, named for the science-fiction cult movie "Plan 9 From 
         Outer Space," was designed by the inventors of the UNIX system, a 
         widely used operating system created at Bell Labs 25 years ago.   
         "Plan 9 is not in competition with UNIX or Windows," said Paul 
         Fillinich, marketing manager for AT&T Software Solutions.  The 
         Plan 9 system is based on the concept of distributed computing in 
         a networked, client-server environment.  The product, including 
         source code, is available for $350.  The full kit will be shipped 
         with a CD-ROM, four diskettes and two manuals.  A partial kit, 
         containing only the manuals, may be ordered separately for $125.  
         The contact number in the U.S. for information and orders is 800-
         462-8146; elsewhere, +1-415-943-4076.

|  The free version is available.  Ftp to
|  plan9.att.com, log in as anonymous, and get the
|  files from /plan9/pcdist.  The distrib.html
|  page now points to them.

I tried booting disk1 on two 486s around here.

One said
	/386/init: file does not exist
	panic: boot process dies: unknown
	(plus what I take to be a stack trace)
A directory listing under MS-DOS indicates \386\init does exist.

The other one said
	exception/interrupt 6
	FLAGS=10092  TRAP=6  ECODE=0  PC=80107d84
	(plus a register dump)

I successfully booted the floppy image from the previous version on both 
machines, so I'm sad to see the new version fail so soon.  Should I try 
verifying the disk image with a checksum?  Or should I try a different 
brand PC?

(I was still waiting for a local SparcStation 2 to become available so I 
can put the previous version up there.  Perhaps I should continue to wait.)

I have put a copy of the plan9.att.com:/plan9/pcdist directory in
ftp.bath.ac.uk:/pub/plan9, for anyone who has a faster route to us than
the states.

It is also available in the alex cache of alex.niss.ac.uk for UK academic

[Apologies if you've already seen this]

I've got my SLC booting from disk.  The command ss/home will set up
a new boot disk (takes about 24 mins).  Caveats:

- boot disk must be scsi id 3 for the ROM monitor to boot from it
- disk probably needs to have been formatted by sunos/solaris, which stores
   a lot of pointless information + a checksum in sector 0, which I have been
   leaving alone.  If this becomes a problem, I can probably provide a "blank"
   sector 0 (there's a magic number, so it can't just be all zeros)
- only V1 of the ROM monitor is supported.  The ELC's are V2.  I will
   probably fix this at a later date.  Apparently a V0 exists also...

P.S.  You really don't want to know how it works! ;-)
P.P.S. Danger!  The other "home" scripts are unaware that the interface to
    disk/prep has changed...

Does this mean that upon purchasing the "Full Kit" I will hold a
"Source License for this product"...

Does anyone have the Legal Speak as to what I can do with this
"Source License"???

Hi all,

I've installed the PC demo, and it mostly seems to work.  However,
when it tries to start the mouse driver (?) at boot time, or if I
start it manually, it exits with the "unknown mouse type" message
after couple of seconds delay.

If I "cat /dev/eia0" it produces output when I move the mouse.  I've
tried a couple of mice, both of which work as normal 3 button/5
byte mice on other systems.  I also tried the other serial port, and
using "aux/mouse 0" explicitly.  aux/mouse ps2, tried just for the
sake of experimentation, exited immediately without a message.

A search of the man pages on plan9.att.com didn't produce anything
useful, and of course, I don't (yet) have the source for the
aux/mouse.

Thanks,
	Jeremy

Hi again,

I should have paid more attention.  The message "unknown mouse
type" really means that: when I switched the mouse into to Microsoft
mode it worked properly.  However, every single 3 button mouse with
a Logitech/MS switch ignores the middle button in MS mode.  I know
the MS protocol supports a 3rd button, but it seems that all the
mouse hardware assumes that the software will break with it enabled.

Has someone implemented a mouse driver which supports the more
common 3 button mouse protocol?

Thanks,
	J

Hello everybody!

Now, after Plan9 is available for everyone, I plan to order my CD-ROM from AT&T.
I want to install it on a 486/Pentium PC. Because I don't own such a beast at
the moment, I will have to buy one. And here the problems start. On what
main-boards, graphic-cards etc. Plan9 will run. The WWW-pages on plan9.att.com
aren't very detailed. I have also read the lists spread in the 9fans mailing
list, but they are from 1994 for the old distributions. 

So here's my question: Is there a list covering the new distribution?
	
Thank you very much for any answers!

Regards,

	Henner

Hello again!

Here I am again, looking for the right configuration...

Has anybody tried to run Plan9 on a Gigabyte GA-586AT(/P256) board?

The Bi-processor boards with the Neptun chip set used by the AT&T folks
are nice, but the Trition boards are faster AND cheaper!

Any experiences?

Tschuess,

	Henner

PS: I hope this will be the last question about the `right' configuration.

I've been playing with the trial distribution floppies, trying to
get the system to boot on an old Dell 316SX, here at work. I can get
it as far as attempting to configure the VGA system, but of course the
default /lib/vgadb doesn't have an entry for my machine. I've tried
hacking vgadb and just adding in an entry for it as a straightforward
640x480, but it just hangs. Sigh. I've got the machine to the state
where it can boot up and give me a shell, but there's no access to
8½, etc.

So the question is, is there any way of getting it to support this card,
or do I just give up on this particular machine?

I have a Gateway PC (486/66) with two 400 MB (IDE) disk drives.  I'd
like to install plan9 on the second drive (hd1) but retain there a
modest DOS partion (D:).  If I install the 4 disk "trial" system using
the orignal "prep", all goes well and I have a system I can boot from
hd1, except that, should I run DOS/Windows again, the D: partition is
gone (the partition table has been destroyed, presumably).  It doesn't
matter if I partition the disk with the D: partition at the start or
end of the disk.  On the other hand, if I try the same things using the
new prep, prep complains with
	error 23: Not enough room for boot area

Aside from the notion of moving most of what's on C: to D: and installing
plan9 on C:, can anyone suggest what I'm doing wrong or what I might try?

Richard

Okay, so I've grabbed the PC distribution from plan9.att.com
and seem to have it running reasonably well on my AT&T 6386/SX WGS.
(Although, it refuses to load on my 386DX40 clone. It says it doesn't see
my IDE drive?!).  

So, short of downloading the man pages _en masse_, how do I get 
more information?  I've printed out most of the documents
available on the Web page under Volume 2.

Thanks!
Andy

Ok, so I tried to install the floppy distribution on one of my PCs today,
and here's what my experiences were (roughly):

9 doesn't seem to want to talk to my Maxtor 7546A drive at all. This is a
plain one-year-old 540MB IDE drive that works fine with linux, so there
shouldn't be any problem with using non-BIOS-oriented I/O. More precisely,
when I booted the first time, it said that it couldn't find my primary DOS
partition, which sure isn't terribly informative, but at least "you will
have to change your hardware configuration" was somewhere close to the
point. After fiddling around with the disk and booting it to a shell, I found
that there's no hint of a /dev/hd0disk, etc, even though #H had been bound.
To make sure that I wasn't going totally nuts, I tried the same floppy on a
variety of other IDE disks (which I can't use at moment because there's
stuff on them). All of the other disks were recognized (/dev entries
showing up, etc), so there's something particular with this one. I don't
know if it's something with Maxtor as a vendor, because one of the other
disks is also a Maxtor. So tomorrow I'll do some shuffling, to see if it
installs ok on another disk.

(I tried the disk on a few different controllers and computers.)

So then to my "opinionated" comments, which may or may not mean anything to
you:

There were seemingly no diagnostics at all telling me if the bind #H failed.
In fact, in cpurc, they're all > /dev/null >[2=1]ed out. I got rid of those
and still didn't get anything. The same goes for the mounts after that,
except that they actually say something when they fail -- they tell you the
command failed (but don't say that they failed because the device didn't
exist). A little more feedback from these commands would have been nice.

The install program looks like the MS-DOS install program (which I grudgingly
had to run for the first time ever today. more on this later.). Admittedly,
I haven't gotten very far into it because of the above, but it's definitely
not my definition of pretty.

And about MS-DOS: I do hope this requirement can be dropped soon. I found
setting up MS-DOS to be quite painful. I can understand the need for
bootstrapping at first (linux and the "others" also had to do the same
thing in the early days), but let's please not get too used to it. :-) In
fact, the linux boot-loader should even be able to boot plan 9 if you
dropped it enough hints on the floor.

It's of course fun to play around a little with the mini-system on the boot
disk. Maybe that's just me.

Last and certainly not least: I (finally) got to see Plan 9 From Outer
Space in a Viennese theater last Sunday. How very excellent! An experience
no one should miss out on.

Ok, so I tried on a different drive this morning and eventually got it to
work. The following information may or may not be useful:

I installed it on my notebook, which has a 340MB disk, 16MB RAM, and an
i486dx4/100. Linux was installed on this machine, but there was a 32MB
swap partition, so I had the bright idea to install the DOS and plan 9
partitions over that. I used one of my other linux boxen to prepare the
floppy (had to replace the "prep" command on it), and proceeded. You don't
need to have much of DOS at all on the disk; all you have to do is:

 - boot with 1st ms-dos disk and exit the setup program as soon as it starts
 - "fdisk" and make a tiny DOS partition (I used 4MB but it could be
    smaller, I'm sure)
 - computer will reboot when you exit fdisk (stupid hardware, stupid software)
 - do step 1 again (wince harder this time)
 - "format c: /s"
 - if you have linux installed on the disk, you need to do an fdisk /mbr
     (please see linux notes below!)
 - replace DOS trash-disk with plan 9 boot disk and type "b".

Here's where I ran into trouble. The place on the disk I was planning to
install plan 9 was in between my / and /usr linux partitions. The plan 9
boot disk booted and seemingly took the first partition on the disk (my /) 
to be the DOS partition and when I told it to install the plan 9 DOS files,
it waltzed right over that. I suspected this when I rebooted and there was
no plan9 directory on the DOS partition. I knew it when I tried to boot
linux from floppy. So we now know that plan 9's install doesn't seem to
know the right way to find the "primary DOS partition."

The moral of this story is to back up everything on the disk beforehand even
if it is on another partition, because plan 9 will zing it ruthlessly --
even though I installed using the "fixed" prep command, it still went ahead
and zapped my /usr partition. I have a feeling that the fix was for
multiple partitions directly after the DOS trash (which seemingly has to be
the first on the disk) and not anything that may be after where you intend
to put plan 9. I'll try to confirm this later.

Ok, so now after / was gone, I just went ahead and put the DOS partition at
the beginning of the disk (as I described above) and went ahead with the
install. ("C'mon Bullwinkle.. that trick NEVER works.." "This time for
sure, Rocky!") Ok, this time it did work. However:

I couldn't get it to recognize the built-in PS/2 trackball or a serial Mouse
Systems mouse. Finally, I grudgingly pulled the Logitech MouseMan out of
my other Linux box, and that did work. I suppose I have to buy another
MouseMan, anyway (they cost $65 here, you know.). It didn't do 640x480x8
vga right, but it does do monochrome ok, as it should. I'm not surprised by
this because my notebook has a Cirrus 6440 chipset and that's still kind of a
rare beast (although XFree86 3.1.1 supports it). All of this fiddling
around meant a lot of rebooting and changing the plan9.ini file (through
the plan 9 install program, probably a silly thing to do). When booting the
install program, the kernel correctly says that I have a 2-slotted intel
xxxxx PCMCIA chipset in the notebook, but when I put in my 3Com 3C589 and
configure it in, it screws up and identifies it as a 1-slot Cirrus Logic
controller. Oh well, I'll see about it later.

It's really cool. In particular, acme feels great and is extremely
well-done. I can't find my break key (tried plokta) - don't know if this is
due to the smaller notebook keyboard or what. Anyway, it's an excellent
job, but I'd definitely recommend getting another hard disk before
installing.

It seems that sometime between 15:00 on July 18th and 09:45 on July 19th
the file that holds the 9fans mailing list got truncated to zero bytes.

I have restored the list as of the 18th and added anyone who subscribed
since then.  Sorry for the inconvienece.  All messages are stored in the

Hello again!

Here I am again, looking for the right configuration...

Has anybody tried to run Plan9 on a Gigabyte GA-586AT(/P256) board?

The Bi-processor boards with the Neptun chip set used by the AT&T folks
are nice, but the Trition boards are faster AND cheaper!

Any experiences?

Tschuess,

PS: I hope this will be the last question about the `right' configuration.

Hello everybody!

Now, after Plan9 is available for everyone, I plan to order my CD-ROM from AT&T.
I want to install it on a 486/Pentium PC. Because I don't own such a beast at
the moment, I will have to buy one. And here the problems start. On what
main-boards, graphic-cards etc. Plan9 will run. The WWW-pages on plan9.att.com
aren't very detailed. I have also read the lists spread in the 9fans mailing
list, but they are from 1994 for the old distributions. 

So here's my question: Is there a list covering the new distribution?
	
Thank you very much for any answers!

Regards,

Just wondering... what do folks without WORM jukeboxes do for

Unix, but that clearly doesn't scale, and doesn't work well
if you have just one machine (at home, say.)  Tar doesn't
do multivolume dumps, so I guess you just need a big DAT
and small disks.

there's been a lot of attention recently to the files in ftp://plan9.att.com/plan9/doc,man.
they are from the old distribution; they are in some cases 5 years old.  we're preparing

We are very interested. We are two students working in the Computer Science

Love too.  We have a bunch of PCs around here that we have been been using
for portability testing.  From noname ISA bus 386/33 to PCI bus Pentium.
I would be happy to give you stuff a try on the different platforms which

Most people who are willing to work with a new OS are skillful enough
figure out most problems.  At least I would hope so.  I would think
the list as it is would work fine.

We could gateway this list into an alt group with out much problem.  I
could do that here at BBN.  A comp group would take a month or so to
create.  Although we could use the members of this list as yes votes
(are we over 100 members yet?)

Setting up a newsgroup (whether moderated or not) in the main hierarchies 
(say comp.os.plan9) takes a fair bit of time and effort - there needs to 
be discussion, voting, and that sort of thing.

One could try to set up a group under alt.*, but it may have propagation 
problems, as many sites refuse to carry them or delay creation until 
somebody complains...

If it's just a FAQ, it can be posted in a number of existing groups.  If 
there's frequent new material, or lots of questions, it probably deserves 
a real newsgroup, bnut may not need moderation.  I would suggest 
comp.os.plan9, but haven't started a comp.* proposal before.

An alternative might be to make a moderated mailing list.  If run under a 
list manager like majordomo, it might not be too hard to set up or 
maintain.  I could probably arrange that here.

a distribution setup to try.

Second, we really don't want to be in the support business, and we're hoping
we can use the net to help us out here.  It would be nice if there was a moderated
newsgroup set up where we could get an FAQ established right from the beginning.
We're looking for someone outside to volunteer to set that up and moderate it.
Any takers?

Thanks to all....

There is now a wait file /proc that allows this. Which
does some really cool things (rob said this). You can
wait for anything based on file permission regardless
of who started what.

I guessed that part; I was wondering *why*.  (Calling it rwait() would
be more parimonious, I suppose.)

What's the recommended way to go about coding modules that have to fork

Question for the Labs guys... why no waitpid()?  Simulating that
requires keeping a list of reaped children, and making sure that
everyone who calls wait checks that list first, and everyone who calls
fork clears it out; no such convention seems to be current, though.

	failed.c:7 syntax in macro expansion: x

I don't understand why you keep beating on this.
The documentation states clearly that the C compilers
do not honor ANSI's standard for preprocessing.
It also says that if you want a real preprocessor,
use cpp, which is provided.

One reason is protest: the ANSI preprocessor
definition is needlessly baroque.  The real reason,
though, is simplification,  not only in the compiler,
but in the programs that result.  I could argue back
that making a variable have the same name as a
macro is bad style.  If you want to test whether the
letter of  the law is met by the preprocessor in the
C compiler, you're going to be disappointed.  If you'd
like a fast compiler that discourages tricky
preprocessing, you'll be happy.

As for us, we're happy.

>>Plan 9 on intel. Can you set up an auth server, file server using intel? 
>>Last I heard, there was support only for the mips/sparc machines as 
>>fileservers.

it isn't on the CDROM, but given /sys/src/9/pc and a little background
knowledge, producing /sys/src/fs/pc wasn't too hard.
producing 9pccpu (CPU server configuration) is even easier.  any cpu server
can be used as an authentication server, so that's that!

(thanks to the Labs we are back in the `use the source' era!)

a 486dx2/66 seems quite a bit faster than a Sparc Classic; i use a dx2/66
as a CPU server, and even with a 24Mb classic as a terminal i tended
to do (cross)compilations on the 486.  i use a very lowly 16Mb 486sx33
as a file server (it doesn't use floating point).  it's adequate for
a small number of users (certainly not the bottleneck at present).

>>The problem with PCs is that if users have them on their desks, most of them 
>>want/demand Windows.

i was expecting that many people here would replace old Suns by PCs to run Windows,
because they don't program much (or they like Visual Basic),
so the intention wasn't to preclude that,
BUT for those who preferred a Unix environment i thought it might be
nice to consider more interesting hardware than Sun provides.

of course, the PC configuration will be chosen to allow people to
run Linux, Amoeba and of course Plan 9 if that takes their fancy.
as cs.wisc.edu!bob observed, the faster Intel and non-Intel clones are
competitive in performance and usually much cheaper than equivalent
RISC machines:

>>I highly recommend the new Pentium machines. For under $US4k you
>>can get a machine that is very powerful (~40mips, 32Meg mem, 540M disk).

it's also nice on the PC to be able to plug in a wide range of cheap special-purpose
cards (although register-level programming information isn't always available).
furthermore, most fast PCs come with a reasonable amount of fast
second-level cache, which can make a difference.

even so, i don't think the 386/486 architecture has got enough truly
general purpose registers for some things i'd like to do
(not really enough for basic bitblt, come to that).
the 64k banking of most non-PCI graphics cards is also a disincentive, and
makes graphics implementation harder and slower.  on a more personal level,
i get dizzy every time i get near the register level programming of SVGA.

90 and 100Mhz Pentium machines, especially with PCI,
should make very good, cheap file and CPU servers.
there are even multi-processor variants.
in those applications weak graphics performance matters not a bit.

unless you are considering graphics or multimedia work (both of
which interest me a bit) and possibly floating-point
intensive work (traditionally a weak area for Intel machines),
the underlying awfulness of the Intel architecture doesn't appear at all
with either Plan 9 (or Linux, come to that), and with those
exceptions i'd certainly consider a fast PC as a Plan 9 terminal.
(in fact, i use a 486 at home.)
it is indeed hard to match the price.

I agree.  I want to do even better and print (or at least read) messages
that say which component caused the error.  As you say, that requires
the fileservers to follow some convention for communicating the information
back.  I was imagining hacking the print routines to clip off the 
proposed trailing :number and return it in some other % verb, but even 
without that it would be an improvement just to see the raw information.

(I mistakenly used perror in the example before.  I really was thinking 
about the %r format, but my fingers are more used to typing the other.)

This has nothing to do with the plan 9 kernel. The errstr is produced by
whatever file system you are connected to. However, while the file
system could be modified to do this it does not seem unreasonable
to expect the application programmer to print adequate information
especially with the werrstr library function and %r format.

The other day, just for fun, I rebooted my file server while I was
still logged on to the terminal and cpu.  Very shortly they noticed
that the connection had timed out, and required rebooting themselves.
In a minimal configuration like this, that's not a big deal, but what
does one do in a larger configuration, with several cpu and file
servers?  NFS has lots of shortcomings, but its one good point is that
recovery is automatic.

Brazil allows file systems to be mounted with a recover option
which does exactly what you ask. The recovery is entirely transparent
to the user.

the sun is perhaps a poor choice for this test because its
mmu and caches are pessimal for anything involving
lots of processes.  the cost of flushing caches and mmu
will dominate any operating system performance.
in other words, the hardware is so expensive that
software hardly matters.

i tried the test on our challenge multiprocessors.

10,000 fork/exit/wait.

plan 9: real time 1.32 seconds.
unix: real time 41.1 seconds.

the unix system had more load, but was still
pretty quiet.  system time was 27.9 seconds.

on our seven-year-old SGI power machines,
the test takes 6.26 seconds.  the time is about
4 seconds on a single-processor MIPS magnum
of the same vintage, so the multiprocessor
part isn't very important.

now scott's test was 1,000 forks on a sun; my test
was 10,000.  on our at&t gnots, with 25MHz 68020's
and awful mmu, it takes 75 seconds to do 10,000.
our modern sparcstation-2 machine takes 34 seconds.
(a newer machine than the magnum that takes 4 seconds.)
you see, suns suck.  they really do.  the processors are
borderline OK but the rest of the system hurts.  yesterday,
quite independently, i was doing some tests of large-scale
memory bandwidth and the suns were laughable.

as for compiler names, the scheme we have is simple,
consistent, and parsimonious.  if crypticness is the
complaint, remember you're talking about a C compiler.

Subject: Re: prices for Entre PCs
	[too expensive for our taste]

The only options available are 1) to wait till summer. We will be doing a
new rfp and awarding the contract to a mainstream player yet to be decided.
2) bid something they don't have. I just got in a pentium a few weeks ago
because they weren't selling them at the time, or 3) Look at buying a
machine that is officially supported by something like nextstep or
solaris and state on the requisition you are planning to run that OS
---cut

I have approval to get 4 machines but the local dealer with wich we have 
a contract with is gouging us, so to get out of the coils, we have to get 
machines that are NeXTSTEP/Solaris certified, and most of these machines 
come with weird mainstream cards.  I need your help in getting a list of 
video cards that work.  I am not that good (yet) with intel hardware and 
would prefer the minimum of problems getting it up to run first.

So if you have any YES - This card runs, please mail me it.  I would 
really love if the ATI UltraPro or something like that worked.  Diamond 
is not too well liked here so thats out.  I was hoping for something like 
the list of supported cards direct from the horses mouth so to speak.

The only NeXTSTEP machine that has ET4000/W32 etc chipset is the NEC 
Image series, which are not as much bang for the buck as Gateway 2000 or 
the other clones.  I know Compaq Qvision probably won't work, so we can't 
get the Compaq Deskpro's. (Local bus is good)

Any idea what hardware the plan9 folks are running (x86).

There is a problem with the plan9 memory management system for the PC
due to one of the brain dead features of the 386 architecture.
In particular, the R/W bit in a user page table entry is ignored when
the processor is in supervisor mode.  This means that copy on write will
not work when the kernel is copying into user space.
For example the following code segment exhibits the problem.

#include <u.h>
#include <libc.h>

char    buf[1024];

main()
{
        int i;

        if (fork() == 0) {
                /* make sure memory is allocated RONLY */
                i = buf[0];

                read(0, buf, 1024);
                print("%s\n", buf);
                exits(0);
        }

        /* wait a second so the child completes */

        sleep(1000);

        buf[1023] = 0;

        print("parent -> %s\n", buf);
}

On plan 9 for the pc, the data read into buf will incorrectly appear in both
the child and parent process.

The 486 (and higher?) fixed the problem but to maintain compatibility
it defaults to the 386 behavior.  On a 486 you need to set bit 16 in CR0
to get the correct behavior for the R/W bit.  Of course, if you have a
386, then copy on write can not be fixed, but you can still run plan9
with a copy on reference scheme... unfortunately, this means your 386
machine runs slower and requires more memory...

The complete fix of the problem, thanks to Dave Presotto, follows:

Here's the changes.  It works on a couple of 486's and 386's so its
probably right.

In l.s (around line 131) change

        ORL     $0X80000000,AX
        ANDL    $~(0x8|0x2),AX  /* TS=0, MP=0 */

to

        ORL     $0X80010000,AX
        ANDL    $~(0x40000000|0x20000000|0x8|0x2),AX    /* CD=0, NW=0, TS=0, MP=0 */

This also turns on internal caching in case it was off.

In l.s add the routine

/*
 *  return cpu type (what is a pentium?)
 */
TEXT    x86(SB),$0

        PUSHFL
        MOVL    0(SP),AX
        ORL     $0x40000,AX
        PUSHL   AX
        POPFL
        PUSHFL
        POPL    AX
        ANDL    $0x40000,AX
        JZ      is386
        MOVL    $486,AX
        JMP     done
is386:
        MOVL    $386,AX
done:
        POPFL
        RET

This returns the number 386 or 486 depending.  I guess it'll return
586 also when I get a chance at a Pentium.

In fns.h add a definition for it:

        int     x86(void);

In main.c in confinit() change

        conf.copymode = 0;      /* copy on write */

to

        switch(x86()){
        case 386:
                conf.copymode = 1;      /* copy on reference */
                break;
        default:
        case 486:
                conf.copymode = 0;      /* copy on write */
                break;
        }

and you're done.

there's a background project here to do some scaling font stuff.
we may use them one day, if the results are good enough, on our
higher-resolution (>130 dpi) monitors.  you need the higher res.
the problem is that antialiased fonts are often poor for day-to-day
use because their fuzziness bothers the eye.  programs like nEwS (or
your favorite pOSTsCRIPT interpreter, for different reasons)
try not to use scaled fonts when they can, but rather refer to
precompiled rasterized, hand-tuned, unfuzzy fonts.  the results
are faster, sharper, more pleasing, and easier on the eye.

There were over 40 newsgroups that `could have been relevant' to
a RFD for Plan 9. I'd rather not launch a huge campaign, as OS
evangelism is a fairly irritating behavior (even when you are
running the |<00L3St 0S in the whole wide world :-).

I should have sent the RFD to this list, but I was planning
to do that only if there was a reasonable support from the rest of
the net - after all, if all the support we got was from users of the
mailing list, why not just stay with the mailing list? Still as an
experiment: if you're reading this list, and you'd go to the trouble
of voting on comp.os.plan9, mail me and let me what you'd vote (and
if you'd vote `no', then what your reasons are).

Support from the people at the Labs is another issue. I would think
a newsgroup would reduce the amount of support mail to the Labs, if
there was a decent FAQ there and people could post answers about getting
Plan 9 up and running.

There's also a the fact that of traffic on this list being hardly
overwhelming (these last couple weeks are an exception).

The purpose of this list is to maintain a database of hardware that is
known to work with plan 9.  This should make life easier for those
people contemplating the purchase of new hardware.  Most of this list
is taken directly from what Forsyth sent me.  Please do not deluge him
with mail, reply to me and I'll try to set up a mechanism to distribute
this stuff.

 The list is starting out for the most selfish of reasons, since I am
in the market for some hardware to run plan 9, I thought it would be a
good idea to find out what to get.  This list will concentrate mostly
on the 386/486 clone hardware.  While the 386/486 machines are looked
upon with derision, they provide the cheapest hardware to run plan 9.
However, most of the hardware is only tested with, and comes with
drivers for, DOS and Windows, and thus may not work with plan 9.  This
list details the stuff that works with plan 9.

BeginBlurb:  
Plan 9 on a Mac.  No more futzing around. 
I could deal with plan 9 on a Powerbook 180.
End Blurb.

Contributors:

Most of this hardware list comes from forsyth@minster.york.ac.uk who
has done yeoman work to contributing to this list.  Actually, come to
think of it, his is about the only contribution ;)

Here is the list of hardware that will work with plan 9.  Other
hardware may work with plan 9, but this list will only list stuff that
is known to work or stuff that I need confirmation on.

-----------------------------------------------------
Bus:
	ISA
	VESA
	EISA (may work with ISA Cards, need confirmation)
-----------------------------------------------------
CPU:
	Intel
	AMD - To be tested by Forsyth
	Cyrix - Ditto
	IBM SLC - Ditto
------------------------------------------------------
Video Cards:

This is the trickiest part.  SVGA cards all have different ways of
configuring and operating high-resolution modes (higher than 640x480
VGA).

	ET4000 SVGA cards work.
	S3 911 cards work
	Paradise cards (reportedly) work.
	Diamond Stealth Pro cards work, with some changes
		to devvga.c and lib/vga.  This is from
		Gary Chapel.

------------------------------------------------------
Ethernet cards:

	WD
	SMC
	NE2000 clones (Reset port address it uses
		       might not work on some clones)
	3Com 3C509 Etherlink III (need to get some fixes
		       to use the driver under very heavy
		       loads)
	3Com 3C503 -- Avoid this one


------------------------------------------------------------
Hard Disk Controllers:

	Ultrastor 14F SCSI (driver is available by ftp)
	Adaptec 1542B/Buslogic 542B (driver is available,
		but hasn't been used very much)
	Forsyth has added the driver for the Ultrastor 14F.
	He has used it on both cpu and terminal machines,
	and also on the file server, running Fujitsu 2624FA
	disks, Seagate 3283N and Sun CDROM drives.

	Standard IDE controllers should work.
--------------------------------------------------------------
Memory:

	8-16 megs should be adequate.  More is better.

--------------------------------------------------------------

Modems:

	High speed modems will work but the kernel does not take
	advantage of the FIFO's in the 16550 UARTS.  Forsyth can
	supply the diffs and the appropriate changes that will work
	for `hayes', which work fine upto 38400.
	
--------------------------------------------------------------------------
Diskettes:

	Stick with 3.5" 1.44 meg or 5.25".  Plan 9 does not
	work too well with 2.88 meg 3.5".

---------------------------------------------------------------------------

Disks:

The pc system on the distribution (Jan 1993 version) supports
IDE disks.  The IDE driver has a bug in it that causes it to fail
on very old Seagate 42 Meg drives (fixed by Forsyth).  Modern IDE
drives work just fine.

----------------------------------------------------------------------------
This is the list as it stands.  If you have plan 9 running on

isspace() is an ASCII-ism.  ANSI C has nothing helpful to say on the topic of
collation and expanded character sets.  if you have input and are prepared to
defend your position, comp.std.character-set.flames.R.us is your oyster.

Ouch.  I know about the funny spaces, but I'm uncertain what the
program is.  Why doesn't isspace() recognise them, for example?  When
awk goes to split input into fields, I can see why one might not want
it to split on the non-breaking-space or the graphic-for-space, but
what about the others?

I don't have RFC821 in front of me, but (unless I'm confused) it
indicates that the SMTP envelope address may be different than the
sender's address (and the sender's address is where one would
presumably want a reply to go).  The example that the RFC cites is a
special mailbox where errors are to be sent could be used as the
envelope address (e.g. the mailing list administrator's address).

I think that your sysadmins are right: the UA should reply to the From: 
address stored within the message.  I think that RFC821 specifies other 
headers that can be used, too, such as Reply-To:.

Hi,
I would like to install Plan 9 from a cdrom mounted on our UNIX host.
The problem is that every filename.
Is there a way to copy files from the CD to the 386 (using mkfs ...)
without having a Plan 9 fileserver ?

regards
Thomas

div64.l is for a 64 bit mips compiler I have been working on.
Just delete the file from the library. When or If I do a 64
bit distribution I will include everything necessary.

No. The /sys/src/alef/test/Y I included with the new compilers
I shipped you compile and run. Some of the tests are supposed
to generate compiler errors.

>> Has anyone ported the plan9 file server to a PC?
>> thanks
>> sean quinlan

i did that a few months ago.  it only supports ISA at the moment
(i haven't got an EISA yet to try), and thus only 16 Mbytes
since i don't compensate for the limitations of the pc's DMA addressing.
(it wouldn't be too hard: the SCSI adapter could allocate some
space below 16meg and copy the data; whether that's sensible
is another matter.)

i run the file server on a 16Mb 486sx33 with an Ultrastor 14F
and two Fujitsu SCSI-2 drives.  (it boots from a floppy.)
the ethernets supported are those supported by the cpu/terminal kernel
and also NE2100 clones, which use the AMD Lance
(another device with addressing problems!).
the 486sx33 serves a 486dx2-66 CPU server and a few terminals.
i can't compare its performance to an SS2; i improvised
a bootstrap for Plan 9 that went straight to the pc via 9sscd.

the only host adapter supported is the Ultrastor 14F.  the driver should
work with the 34F with at most minor changes, if any, but my 34F
and not-quite-VESA motherboard don't agree, so i haven't been able to test it.
a bus-mastering VESA device can avoid the 16Mb DMA restrictions, however,
making an ISA/VESA pc more useful as a file server.
i have an Adaptec 1542B/Bustek 542B driver, but it doesn't drive discs
(it runs the 1542B in target mode, not initiator mode);
still, most of what is required is there.

it might become possible for individuals to acquire the system.
steps are being taken in that direction.  the decision depends
on various factors that are not influencable by outside campaigns
and there is no promise of a successful conclusion, however.

DOS doesn't like a file or directory name of "aux" or the files
/dev/c: and /dev/a:

The way to do it is to boot from the floppy, use the floppy as
your file system and then copy the files and directories
from the floppy to /n/c: using plan9.

(ie mkdir /n/c:/386/bin/aux, etc)

Bob.

Hi 9'ers,
 my question is of the pc installation. We've
always used the original 1.44 floppy. In
"Configuring for a PC", it is discussed a way
to copy the boot files to a disk to use as the
boot disk. DOS doesn't like the AUX directory
in /386/bin. Even if the files are zipped, then
expanded into DOS, it refuses to create or 
maintain this directory. How have others got 
around this? Similarly, one may copy the image 
(pcdisk) to a floppy, but of what utility is this?
  Thanks in advance, --Jerry

Hi 9'ers,
does anyone have any examples of ALEF code they might
share? (Or know of an FTP site?) It needn't be all that 
complex, just something to demonstrate the concurrency 
primitives. I intend to write a simple demonstration 
program; like the "classic" dining philosophers.

Also, is SPARC and MIPS the only supported platforms?
Specifically, has anyone ported the compiler to the PC?

Any input is appreciated.
             Thanks in advance. --Jerry

if you want emacs, you can run it almost anywhere
else; why bother to run it here?

if you trust us enough to try our operating system,
why not trust us enough to try our other software,
like the window system and the editor?  why not see
if we have a good idea in our structuring of the
libraries and header files?  why marvel at the
compatibilities of the system when some of its
best ideas might be incompatibilities?  why install
a replica of your familiar playground with all these
new toys around?
