From IBM:

Under AIX 3.2, there is a new address space model enabling larger data spaces to be allocated to an application.  The o_maxdata field in the a.out header gets set to the amount of memory needed.  This can be set with the -b option to the linker.

For example, to use 8 256M segments (the maximum) the command to use is:
    cc -o program program.o -bmaxdata:0x80000000
(The number 0x80000000 is the number of bytes, in hexadecimal, =2Gbytes of addressable space)

Under AIX 3.1 a shared memory model must be used.  I have some info from IBM on how
to accomplish this if anyone is interested.

You could write a script that uses the "adduser" command.  You would
have to figure out which prompts would be where and write a batch
file that would contain all the correct inputs.

Also, I have posted source code in the past that will perform this
function.  You need to located the "Shadow Password Suite".  It was
posted to comp.sources.misc and is currently at version 3.1.4 (which
is patchlevel 17).  Please keep in mind that this is not a product
of IBM or Locus Computing Corporation, so DO NOT contact them for
information.  The "newusers" command will do most of what I suspect
you want.  [ You must undefine the SHADOWPWD macro to get the
behavior that AIX v1 requires. ]  If you have any questions about
this, feel free to drop me a note.  The official archive site is
ftp.cs.widener.edu, the directory is pub/src/adm, and the file name
is "shadow" followed by version and other information.

Subject: aix equivalent to PKT_IOCTL for pseudo-terminals
Date: 15 Apr 92 18:55:30 GMT
Organization: Department of Computer Science, University of York, England

I must write a program that controls a pseudo-terminal.
It must know when any program running on the slave side switches
on raw or cbreak modes (or posix equivalent).
The slave-side programs are not under my control, so I cannot have
them change the ^S and ^Q settings to force PKT_DOSTOP/PKT_NOSTOP to be sent.
Both Sun and 4.3 BSD-reno provide (different) ways to do this.
On each system, there is a pseudo-terminal mode that will cause
the master tty side to be notified (via a PKT_IOCTL flag in TIOCPKT mode)
when any process does an ioctl on the slave side.
The process controlling the master side can then check the setting
on the slave side to see what has changed.
Since I cannot find a definition of PKT_IOCTL on my 3.1.7 system,
I fear the worst, but I ask the net anyhow:  how do I get the right
effect under AIX 3.1.7?
Note that I CANNOT UPGRADE TO AIX 3.2!!!!
Is there a patch?  Has anyone got the source for a usable replacement I
could compile and load into our kernel?
It needn't be pty compatible, just usable.

As mentioned in another follow-up article, the problem stems
from the change from 4.3 to 4.4 sockets.  I saw the same
problems at AIX 3.2 Beta level 9149, but I talked to one
of the developers about it and was told that they were
modifying the libraries to work with both socket 
conventions.
In fact, when I updated our machines to the product
level ("golden") AIX 3.2, the problems disappeared.
Are you still having this after having installed product
code, or are you still running beta-test code?

Howdy, 

This question may not be appropriate for this newgroup, but as it
concerns an IBM RS/6000, I thought what the heck?
I'm trying to perform a remote backup from an SCO UNIX (sigh) box to an
IBM RS/6000.  Unfortunately, rdump does not exist on the SCO box.
Here's what I have so far:

on SCO: 
find / -depth -print | cpio -ovct | rcmd (rsh) RS6K dd of=/dev/rmt0


Pretty obscure, eh?  Anyway, it seems that I can't write directory to
/dev/rmt0 this way.  If I change my of=/dev/rmt0 to of=filename, I get a
huge file that I can then backup to the tape.  This kinda works, but
there has GOT to be an easier way to do this.  Any thoughts? 


Thanks, 

Dave

P.S. Please E-mail and I'll post a summary if anyone is interested.

Yes, we have been using the automounter for quite a while, probably
since 3003.  The automounter comes from Sun.  There wer quite a few
fixes along the way but you don't say what level you are at.  Last
fall (3.1.5) there was pmr0099x that fixed a number of problems.  More
recently I got a23857 (2006) that was a great improvement, it 
supports direct maps.  This is being implemented for 3.2 now, but
it is not ready yet and I didn't note the APAR.  This will be a Sun
4.1.1 equivalent.  I compiled amd with no problems and even did
a little testing, but it is quite complicated and I only read the
manual a couple of times.  Maybe a few more and I would start to
understand it.

I was installing elm and mush on an RS 6000 and felt the need to verify
that the /usr/spool/mail/USER file was being locked properly.  To test
the locking I wrote a small shell script that cated the passwd file
together several times to make a 250K file.  I then had 2 other hosts
send that file to the RS6000 30 times in 30 different mail messages.
The 2 other hosts were a DEC system 5400 running Ultrix 4.1 and an IBM
RT PC running AOS 4.3.

Here is the shell script, (called send.junk)

#!/bin/sh
x=0
while [ $x -le 30 ]
do
	x=`expr $x + 1`
	echo $x
	( echo "Subject: DS5400 ${x}" ;echo ; cat /etc/passwd /etc/passwd ) | /bin/mail mbrookov@rs6000
done

I started send.junk on the 5400 and RT and waited for them to send out
10 messages.  I then ran /usr/bin/mail on the RS6000, deleted the first
6 messages from the 5400 and then typed q and a return to exit
/usr/bin/mail.  Mean while the RT and 5400 were still sending junk.
After send.junk exited on both the RT and 5400, I checked my mailbox.
Several messages besides the 6 that I deleted were missing.  Elm and
Mush have similar problems to /usr/bin/mail.

The files section of bellmail's man page lists /usr/mail/*.lock.  I
have observed bellmail creating /usr/spool/mail/$USER.lock.  If you create
this file and then send your self email bellmail will just delete it
and deliver the message.  If you put an flock on it, then bellmail will
wait for the lock to go away and deliver the message.  /usr/mail is a 
symbolic link to /usr/spool/mail.

The man page for /usr/bin/mail does not have any reference to a lock file.
Does that mean IBM does not intend for /usr/spool/mail/$USER to be locked
when it is updated by /usr/bin/mail?

The modes of /usr/spool/mail were set to 775 by default.  I changed
them to 1777 when I realized it was using lock files.  /usr/bin/mail is
not setuid or setgid,  when I saw the 775 mode I thought that it should
be.

Sendmail seems to be working properly.  I think the problem is in
bellmail or mail, but I could be wrong.  If I start up send.junk on the
RT and 5400 and let them run without running /usr/bin/mail on the RS6000,
all 60 messages are properly delivered to the RS6000.

Does anybody out there in netland know how to make /bin/mail and
/usr/bin/mail lock properly?  Does anybody know how /bin/bellmail is
doing its locking?  Has anybody else even noticed this problem?
Is there a way to tell if a mail message has been walked on?  I could
not find any interesting messages in the log files.

The RS6000 is running AIX 03.01.0007.0025 and is a model 550.

I am in the process of installing NFS as a client on a PS/2 running AIX.  The

get the following messages: 'You are not the super user' followed by 'giving up

Now I'm doing this as the super-user so I suspect the problem lies elsewhere.
I then noticed that there were no active biod processes running under AIX.

Reply-To: davide@cadillac.cad.mcc.com
Organization: MCC CAD Program, Austin, Texas

I'm stumped and I hope someone can help me.  I'm trying to port the
Scheme->C system by Joel Bartlett at DEC Western Research Lab (decwrl)
to the RS/6000.  I have it compiled, linked and running, mostly.  The
problem I'm having has to do with saving the stack for a scheme
continuation. Simple continuations, ala lisp's catch/throw and C's
setjmp/longjmp, seem to work OK.  The problem is with a continuation
that wants to restore a part of the stack where the restored part
was copied from the stack to a buffer at an earlier time.

The first thing I need to be able to do is to call a routine from C
that returns the stack pointer for the called function.  The current
stack pointer and a saved stack pointer will be used to copy the
relavent parts of the stack each time a continuation is created.  In
assembly language this would not be very difficult, I don't think.
However, I'm not sure I understand the subroutine linkage, stack
layout and register usage enough to get it right.  And I know I don't
know enough about the assembler to get an assembly language routine
right. I have read the "Assembler Language Reference" manaul as well
as parts of the on-line info stuff, so I understand the basic assembler
syntax and a little bit about the stack layout.  

Does anybody have a routine to do this? Can anybody point to a simple
assembly language file some place in the manuals or on-line
somewhere?

My next question has to do with saving registers.  Does setjmp() save
all the registers?  And does longjmp() restore all the registers?  Its
seems they ought to, but I thought I'd ask just in case they don't. :-)

I'll be most appreciative of any answers or suggestions anybody might
have.

Thanks!

Hello

Our machine (IBM RS 6000 AIX 3.1.5 3005) has been erratically bouncing
outgoing mail. An example of the kind of error it gives is:


From: MAILER-DAEMON (Mail Delivery Subsystem)
Subject: Returned mail: Service unavailable
Message-Id: <9203202251.AA30570@mail.physics.utah.edu>
To: pullin
Status: RO

  --- The transcript of the session follows ---
554 asterix.eng.buffalo.edu.tcp... 554 Service unavailable
554 arg-net@asterix.eng.buffalo.edu... Service unavailable



That is, it seems that for some reason it decides not to use the name
server and it tries to open a tcp/ip direct connection with the mail
destination. If the connection cannot be opened (network temporarily
unreachable, or if it is a foreign address with no direct connection)
it bounces the message. It should be noticed that usually re-sending
the message immediately does not cause any problem (the message goes
through OK). Sometimes maybe it has to be re-sent twice (it bounces
also the second time). The IBM people could only suggest "try
rebooting the machine" which did not help. I am using ELM 2.3 PL11 as
mailer and sendmail. I had a look at sendmail.cf and seems configured
OK. For instance it usually accepts without trouble "difficult"
foreign internet addresses, which proves it is using name servers to
send the message.  Again I remind that the problem is only sporadical
and is not reproducible, it happens about once a day to me, and I
usually send 20/30 outgoing messages a day.


Anyone can give me any hint? As you may infer from the wording of the
above text I am no expert in sendmail, tcp/ip or nameservers, so any
suggestion is welcome. Please reply by email, I can summarize if there
is interest. Thanks in advance.
