Tell that to MicroSoft. After all, the first thing you see there on a
new install is far from the

Have you tried phoning them ?

Then find one that's in NL. (I took that posting just for an example.
I didn't look carefully for other places).
You're not living in Germany, so what ? You can still phone them right ?
Next time, probably you want to find place one block from your home :-)

Ever heard a user got confused using FDISK and trashed his partition

Ever tried to install different mouse driver for windows and make windows

Why not ? I've seen people buying PC with DOS and Windows installed, same
with UNIX. These people don't want to know how to install DOS or Windows.
(I know some people who don't know how to install DOS and Windows, all
they really care is Word Perfect.)
Also some company will sell you the machine with UNIX pre-installed.

Several people have pointed out that installing UNIX was easy.

The symptoms described by John sounds suspiciously like problems I had
here for quite some time also using sz/rz. Here's what I eventually
found:

There was a simple handshaking problem.  I'm using a Trailblazer+ locked
at 19200 to the cpu but had callers at 2400 having blown transfers and
transfer rates (with all the errors counted in) of less than 300 bps.  A
temporary fix was to use the sz -w1024 [filename] command to send files
with a window of 1024 bytes.  This forced the speed a bit slower than a
normallly operating 2400 connection but it at least worked temporarily
by forcing a break every 1024 bytes of transfer to allow an ACK/NAK to
come down.  This blows the streaming capability of Zmodem but DOES work.
Note that this is with sz on a Unix machine sending to a DOS machine
with a 2400 baud connection.  The same problem is likely if you are
connecting at 9600 to a system with a modem locked to it's host at
19200.  UPLOADING to such a system (using rz) probably won't cause
problems.

I cured this royal pain by installing FAS drivers and 16550AFN Uarts.
The previously non-existant handshaking now deals with it all and I no
longer need the sz -w1024 command. A simple fix in the end. BTW, I'm
using a Digiboard DigiCHANNEL PC/8 under Microport SYSV/386 here.

As usual, your mileage may vary and this might not even be the problem
you two are having but it's a place to look.

Good luck.

This `is Unix dead' is one of the most stupid subjects I have ever seen
discussed.
  1) Some people seem to be confusing operating systems with the
     applications that run under the OS.
  2) Unix is the only OS that will run on (effectively) every computer ever
     manufactured.  Nothing else offers this - there _is no alternative_.
     (Even ignoring the fact that the Mac and PC operating systems only
     run on one hardware platform each, they still often have difficulty
     operating with add-on hardware even though it is intended to be
     used for them specifically!
Prediction:
  Now that Unix can be run on PCs, and the price barrier of all its
  benefits has fallen, and we are seeing many more user-friendly
  programs being developed for it, it will become the underlying
  operating system of choice.

It has its drawbacks, but nothing like those of its `competitors'. Sure,
Windows etc. will probably still be popular in 20 years time.  But what
do you expect? Some people still program in Cobol, for heaven's sake!

TIP is green, RING is red.  This is the wire pair in the middle of
the modular plug.  Wire pairs start with the two wires in the middle
of the plug and go out towards the edge, so on a 6-wire mudular
plug, the pairs would be 3-4, 2-5 and 1-6.  On a standard residential
installation, yellow is ground and black is transformer +.  The trans-
former was used to light the dials of Trimline and Princess phones.
Newer lighted-dial phones use a low-current LED which draws its
power directly from the phone lines.  Blue and white depends on your
application.  Is this the information you wanted?

Subject: Re: Unlocking named pipes (solved + question)
Keywords: named pipe FIFO
Date: 18 Nov 92 00:06:43 GMT
Followup-To: comp.unix.questions
To:       [e-mail]


Well, after receiving very few responses to my problem, I did a little
poking around in the SunOS kernel config files to try and find an
answer.

Basically, my problem was this: I was using several named pipes to
receive the output of several 'zcat file...' commands, and was then
using 'sort <ops> -m pipe1 pipe2...' to merge the named pipes
together. The result was that I could merge several large compressed
sorted files, without having to decompress them to disk.

The problem was that after running for a while, the process would
freeze and all processes would go into IW. I thought it was strange
that this would happen all by itself, and indeed it didn't. At the
same time, I was testing this process on several smaller files, using
named pipes (different pipes, of course).

I then noticed in the kernel configuration file, the option "options
FIFOCNT=10' was being set. Sure enough, in the "Sun System and Network
Administration" manual, I stumbled across the following, under "Tuning
IPC System Parameters":

    FIFOCNT determines the makimum number of FIFOs that may be in
    use in the system an any given time. Attempts to write more
    than FIFOCNT simultaneous FIFOs will block until some FIFOs
    are closed, releasing system resources. In the current
    implementation, FIFO buffers are allocated in non-paging
    memory, and can lead to system lockup if indiscriminantly
    allocated. This restriction make be removed in a future
    release.

Well, that was the problem. The job would run fine as long as I was
using <= 10 pipes. When I fiddled around while the job was running, I
caused several of the pipes to block, and sort would stop, and all
other processes would eventually stop since none of the pipes would
clear until sort was done.

I've rebuilt the kernel with FIFOCNT=16 to help me out temporarily,
but my question is this: is it really true that only this many named
pipes can be used at once *in the entire system*? What if 2 users try
to do this at the same time? Or 2 jobs for that matter?

It seems very unfriendly, for such a nice feature.

Yes and the name says exactly what it does: manage windows. It doesn't handle
buttons, scroll bars, check boxes, pop-up menus, etc., etc. An OPEN LOOK app
is still an OPEN LOOK app when run under Motif. After a few clicks, you have
as many user interfaces as applications, except for the borders.

I agree with that, compare it for instance with OS/2's E.EXE or Windows'
NOTEPAD.EXE. They're very limited, but very easy to use.

Well, I've seen several terminals with a PC kind of keyboard (Philips and NCR).
I wouldn't be surprised when they are in fact PC keyboards.

Well, Open Look specifies a helpkey, it's a standard Open Look feature. Don't

That's not the case for the PC terminal emulators I know. Most use some kind of

<sigh> Copylefted means that you can't change the code without giving away
the source. It doesn't mean that you can't *sell* the code (and/or derived
binary). RTFC (Read The Fucking Copyleft) or RTFGM (Read The Fucking GNU
Manifesto)!!! The copyleft explicitly permits commercial purposes. The only
but is: don't change the sources without giving them away.

Well, newer implementations of vi are happy with cursor keys. Elvis even has
a menu (Wow! Look what I get when I press \ twice! :).

Well, this version of Elvis does both (and more)...

Good point. No system can satisfy the "learn barely enough to get by"

Well, let's see:

(let's take book editing software for an example)

FrameMaker:  about $3000 (if I convert the swiss price to US$, might be
                          less in the US, however)

You get almost the same under UNIX from

Emacs & TeX:       $0 (maybe you'll have to add media cost)

Or take some table editing programs (spreadsheets), that offer macros:

Excel:  well.... $500?
Perl:              $0

Maybe you start to understand now why I just *love* UNIX... it just
compares favorably with DOS, and I don't give a **** about
"user-friendly" interfaces which seem to be in the way all the time (to
the experienced user, at least).

Did you ever look at what the cost is for adding your DOS/Windows-PC to
a network? What a bunch of different hard- and software you need to get
this to work? Well... it was all built into my UNIX box, and it worked.
This is what I call user-friendliness.

no, the university should not issue manuals.  I studied and worked at a
university for the past 10 years, so i feel I have a grasp on how that
situation works.  the manuals were available, which is all I need.  I
could get the manual for anything, because there was one copy at the
help desks sprinkled around the campus.  If i buy software, i expect to
get manuals.

i consider manuals and online help to be two different things.

Yes, UNIX apps cost more, but that's because most of them are designed for
multi users. If you buy a multi user version of DOS/Windows app it would
cost the same. How much is Brief text editor (for example)?
I've some programs that have competitive (same) price as UNIX apps.

That's not UNIX problem, it's the stupidity (cleverness) of app developers.
FrameMaker on UNIX would have the same interface as the Windows version.
If you run a DOS (or windows) application under Windows or OS/2, it would
still have the same user interface right ?

The UIDs are stored in the (struct user).  They are u.u_uid and u.u_ruid.
Without giving away too much, that's where the system looks for things
like access() and so on.  For a really bad time, check out the source
to suser().  It will convince you of this fact.

Unfortunately, now that we know the data is in the (struct user),
I won't be getting out my source to a XENIX renice ...  This also
means that the device driver idea won't work since the other processes
u-area may be anywheres.

Friendliness and easiness to use varies from user to user.  So use the
editor you find friendly, and let others use the editor they find
friendly, and quit yer bitchin'.

BTW, I use GNU Emacs (on my UNIX box), which beats the snot out

Any program that might run on a variety of terminals and relies on the
existence of function keys is inherently crippled.

F1 is not an intuitive label, I don't see the need for it AT ALL in
the world of "user friendliness".  Certainly a key labelled "help"
makes much more sense (though not in the context of UNIX).

Subject: I/O mapping from /bin/login
Date: 18 Nov 92 07:50:46 GMT
Sender: [e-mail]
To:       [e-mail]

Hi. I'm trying to write a program which will call up a remote modem
and let the user login (as a dial back security measure).

I have it almost working (thanks for source contributions guys), but now
something *very weird* is happening.

The program runs very successfully, calling up my remote modem and
displaying "login:" on the terminal. It then awaits input from the
remote modem and upon getting <cr> prints "Password:" on the remote
modem.

All is good up to this point, but now things go strangely. Somehow,
/bin/login changes where it expects its input from at this point. It
awaits input from the starting terminal of the dialout program. If it
is given a bad password, the program will then print "login:" on the
correct remote terminal again, and *again await input* from the correct,
remote, location. This can be repeated for as many bad logins as /bin/login
allows.

If a correct password is supplied (from the wrong terminal, of course) then
the user's login shell is started, any .cshrc output appears in the correct,
remote, location, then the shell freezes awaiting input from the starting
terminal of the dial program. Not helpful.

The terminal is having /bin/login pointed at it by the following lines:

    /*
     * Redirect /bin/login's stdin, stdout and stderr (no error
     * checking here.)
     */
    dup2( fd, 0);
    dup2( fd, 1 );
    dup2( fd, 2 );
    dup2( fd, 3 );

    /*
     * Execute /bin/login with the serial line as its stdin, stdout
     * and stderr.
     */
    execl("/usr/etc/getty", "usr/etc/getty", "D2400", "-", (char *) 0);

Any problem here. The descriptor in fd is the one that successfully
read and wrote characters to the modem for the dialing command.

Please reply by e-mail--I can't keep up with the volume in here.

Thanks in advance,

It means that the C compiler can't handle 8bit identifiers, e.g.
Nasenbdr (you might see the d on the left as v or \344, depending on
your configuration). Most C compilers can handle 8bit characters in
strings and comments, though.

I don't know about lex, but flex has an option for exactly that, i.e.
producing an 8bit scanner. The comment above only refers to identifiers,
not the input text.

Date: 18 Nov 92 16:32:23 GMT
Sender: [e-mail]
Nntp-Posting-Host: song.bellcore.com
To:       [e-mail]

We have developed an application using (n)awk, and convert to C
using awkcc when we want to run the program (for purposes of speed up).

The program takes input from stdin and writes to stdout.
(When stuff is read into an awk program some other variables
like $0, NF, etc, are also set.)

We want to change the input/output mechanism of our program,
specifically the awkcc generated version, as that is what
we will be using in the final product.

We want our program to be implemented as a _function call_.

That is, instead of reading stuff from stdin, our C program
is passed a parameter which would be the input string, and returns
an output string (instead of writing to stdio). As our program takes
a long time to initialize (it has a very large BEGIN structure),
we do not want to do the initialization for every input.

The awkcc generated code is very obscure, and it seems a non-trivial
task to implement our awkcc generated program as a function call.
We did locate the function which opens the input as a stream of type FILE *.
However, it seems trying to change that would in turn entail changing/rewriting
a whole bunch of code. We are looking for help to solve this problem.

One way to get around this problem is to have a parent process which
connects via pipes in both directions to a child process (our program)
which is started up once.  We then communicated with the parent C
program.   But in our case, we DO NOT want to have about 48 different
child processes running for 48 the different sources which can access
our program on one machine.

That's why we are looking into implementing our program as a function call.

Anyone who can offer some help, please send me email.  Thank you!

Preamble: The system is SCO unix 3.2.2.

Can anyone tell me, if I can get telnetd to preserve it's start-up env.
var.s?  What I'm trying to do is this: /etc/wrapper is small program, that
will read the peer-address of its input-socket, set an env.var. (say IP) to
that adress, and then exec its arguments.  Thus when I put:

telnet stream tcp    nowait  NOLUID /etc/wrapper telnetd

in inetd.conf, it ought to make the IP available to telnetd and all of its
children (login, sh).

But no.  No matter what I try, my IP gets lost somewhere.  I have som kind
of hint, that login will destroy most of its env. unless started with a -p
option, but how can I do that (since telnetd starts login, the way *it* damn
pleases)?

Maybe im doing this the wrong way; Can I get the sources for a telnet that
will report it's IP-adresse. and perhaps make it available for the subsequent
processes?

((Gripe: I don't really understand why telnetd doesn't care *anything* for
it's peer adress, but takes great pain to report terminal device id.  IMHO
the latter thing is very maginally useful, but the peer address is handy
for determining login terminal characteristics a.s.o.  I'm aware, that
terminals were once hardwired, but *dammit* that's ages ago.) Sorry about that)

    if you only want my opinion, then you are "doing it wrong",
but if you want information you can use then here it goes: You can pass

environment variables to your process but NOT parmeters
Under UNIX SVR3.2 (not familiar with prev. rel) login is defined as:

login [name [env-var ...]]

login: root    TERM=vt100 NAME="unix guru" OPTIONS="NOMENU,EXPERT"
password:

after login is successful, try this:
echo $TERM $NAME $OPTIONS
they should be set to the values you assigned to them at login.  These
variables are governed by the same rules as ordinary environemnt vars
so you may NOT use 1=first_parm 2=second_parm and then use $1 & $2
login is smart and will log you out if you use an invalid identifier.


good luck

They are users.  And important users.  And they shouldn't be neglected.  I'm
sure vi is small enough that it can be included with every version of unix
until time ends, just like dos' EDLIN.  But there should be an alternative,
and not emacs.  An easy to use, friendly alternative.  That alternative should
come on every unix system.  It should be powerful and configurable.

Let's face it: unix users are users too.  But they are a miniscule subset of
the number of people who COULD be using unix.  Not only instead of DOS and
Windows, but instead of not using computers at all.  A powerful, compatible,
scalable, layered unix could make more people less afraid of computers then
the plethora of incompatibilities we have now.

    I see your point. I agree that currently many powerful
applications are hard to use, but that is due to their poor design. I hope
you would understand that a lot of "powerful applications" you have
mentioned (in your previous postings) were made more than a decade ago.
The user interface technology has developed so much since the beginning of
the 80's and a lot of the features in the older applications can be and
have been incorporate into the new GUI.

    Of course, I agree that the current GUI technology has its
downsides. It is still in its infancy. I think what we should do is trying
to improve it, not clinging to the old methods.

    I believe what the programmer should do is to deliver the power of
the computer to every user, regardless to their knowledge in computing.
How good is a powerful application that no one can use?

    Let us look at the impossibility. Our ancestors have conquered
many impossibilities. They may laugh at us if we now say "it is just
*impossible* to make a powerful application easy to learn and easy to use".
I would always acknowledge the difficulty, but not the impossibility.

    If a user finds an application too difficult to use, that is not
his fault. That is the designer's fault. And believe me, we can correct
it.

Sincerely,

    Ioi.

Doing "man regexp" on my Sun turned up a C library for regular expression

Lots of discussions have been going on about the topic whether Unix is
dead. From my (biased) observation, many people have been missing the
point. Before you posting more irrelevant materials, can you guys think
twice - " What is Unix? What am I defending / attacking? ".

I don't know  what Unix is, but I can give a list what Unix is not.


Unix is not VI, EMACS or C-SHELL
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    These stuffs are only the *applications* of Unix. They distinguish
Unix (somewhat notoriously) from other OS's. Yet they were designed and
implemented before my grandad was born. They do have their merits. I just
don't think by arguing about their merits can help the future of Unix.
What really makes Unix special is its capability in multi-tasking,
security, portability, distributed processing .... and the list goes on
and on. But please, exclude VI.
    (To please the VI fans - VI is something about personal taste, and
I suppose all of you love French wine, too. Please post your support of VI
to soc.culture.????. I would love to read them)


Unix is not a toy for the computer scientists
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    The reason of the development of computing originated from
outsides of the field. Now that we have such a splendid OS like Unix, why
should we restricted its use to the universities and the computer
literates? Why shouldn't a casual user be able to use it? In a few years
everyone will be running a 1000 MIPS PC in their home. They need the power
of Unix. And God (aka Computer Scientists), let these poor soles have it.


Unix does not have to appear as a complicated system
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    Yes, Unix *is* a complicated system, but it doesn't have to appear
so. Not every user has to handle this complexity. One system needs only
ONE sysadmin. As long as I can get my Ferarri fixed by someone, I am
absolutely eligible of owning and driving it.


Unix is not a static object
^^^^^^^^^^^^^^^^^^^^^^^^^^^
    Why can't Unix evolve? By stressing how wonderful Unix is now can
only limit one's vision about the future of computing. OK, I repeat, Unix
is wonderful, but it still has some problems. Find them out and fix them.
Most of the supporters of the old features of Unix are, surprisingly, very
young computer scientists. It is interesting to see many young men/women
in a young industry talk like their grandparents. Where have they lost
their vision and creativity?


Unix is not immortal
^^^^^^^^^^^^^^^^^^^^
    Now there comes the tough part. Unix is not dead, I assure you,
but it will be. Man is not immortal, nor is his creations. No matter how
brilliantly designed and how adaptive Unix was, its foundations will
become its limitations. In a rapidly changing world new products will come
out and replace the existing ones. The replacement of Unix is a sign of
progression. I love my old friend Unix but I would be very happy to see it
die. They day that Unix finally steps down will be an milestone in the
history of the computer, just as was the day when Unix was born.

    Is it possible to capture to a file the output of the ttypa scrren.
    Without brian knowing. :)

    I have Unix on my amiga at home (don't laugh) and wonder if it is
    possible.

    Please reply via email...

    A few days ago I posted a query about how to increase the number
of rows displayed in a terminal window so that 'full-screen' commands
like emacs could make use 35 lines instead of the usual 24.

    I got some responses that suggested "stty rows 35" or "setenv
LINES 35". I've tried both and, while they do alter the terminal's
behaviour, they don't give me a 35-line screen. What I'm getting looks
like this: lines 1-24 after a screen-clear display correctly, but
lines 25-35 pile up on top of each other on the 24th line.

    So maybe I didn't ask the right question. What I'm trying to do is
make the best use of my laptop screen when I dial into my machine
using a modem and terminal emulator. Does the fact that I'm dialing in
make a difference? I'm sure there _must_ be a way of working with more
than a 24x80 display under these circumstances.

    Any and all suggestions would be appreciated!

    Michael

Hi, netters.
This question has to do with cnews software, so may be
it is more appropriate to post it to some other newsgroup,
but i am not sure which one, so here it is:

i have just installed cnews on the server which is our mailhost -
and everything works fine. Unfortunately, i had to reinstall it
on some other machine; it works ok so far - i was able to post
articles to the test group; i used rsh to execute uux on the
mailhost (changed sys file under /usr/lib/news);

my problem is: what happens when uunet sends batches to my mailhost?
as far as i understand, rnews still must be available there, right?
another words, i can not clean up my mailhost in terms of cnews
software, can i?

Thanks in advance for any suggestions.

Date: 19 Nov 92 21:55:44 GMT
NNTP-Posting-Host: bcserv.wustl.edu
To:       [e-mail]


I'm totally confused.

I find that I cannot get the select() system call to
correctly identify when there are characters waiting
on a file descriptor that I have opened with 'open()'.

It *does* seem to work for the fd associated with stdin.

The attached piece of code illustrates the difficulty.

It simply reads chars, at 1/2 second intervals, from either
either stdin or the device given as it's argument.
Before each read, it shows the status that select() returns as
to whether there are chars to be read.
(1 = pending, 0 = buffer empty)

The idea is this:

    run it on your tty, (first as stdin, then as an argument to be opened)

    type a blurb of garbage, (and hit return if not in cbreak mode)

    and watch as it reads off character by character.

What I find is that it works perfectly for the first case (run from stdin)
but totally fails for the second (where it opens your tty).

I have tried many variations on this:
I have used a real serial port as opposed to a ptty.
and I have verified that the termio settings don't effect the problem
as far as I can tell with the information reported by 'stty -a'.

Any help would be greatly appreciated.

Just after glancing through the code, I'd say that what you could do is
(assuming your system echos characters back rather than relying on local
echo) place a system("stty -echo");, or the equivalent, and see if that
helps anything. Place that call before the input for the password, then
system("stty echo"); after it. I don't know if it works myself, since I
don't have a UNIX system to run sudo on yet [yet :)], but my guess would
bne that that would work.

Hope this helps,
