yes, and the new pcnfs docs should have been distributed with it too
but the docs are on cd rom and it's a different organization and blah
blah blah.  sorry.

Normally new ports like this new version of the automounter or the
new version of pcnfsd are not distributed until the next major release,
but one of the benefits of selective fix is that it allows to send out
new things like this more quickly.  But the docs don't go at the same
time.

The next time I send something out with substantially new docs I'll 
make a valiant effort to try to send some kind of version of the docs
along with it somehow.  Easier said than done.

This bug has been fixed but the PTF hasn't made it thru all the test
cycles and stuff yet.  Give it a few more weeks and then call up and 
order it.

If automounter acts different on our machine than on a Sun then we're
broken.  Period.
Call it in and we (probably I) will fix it.

This is strange.  The files in the /usr/lpp/bosinst come with the BOS.  When
you did the initial installation of the machine, those files, including
bosmain, should have been placed in that directory.  Either they never got
placed in that directory, or they were removed later.  Either way, the
system backup which you made using mksysb is no good, since the utilities
needed to restore it (ie, bosmain et. al) do not exist on the tape.

Subject: Rigging up telnetd(1) for an application
Organization: Georgia State University
Date: Wed, 11 Nov 1992 18:38:57 GMT

We wanted people to be able to telnet into our application on an RS/6000
running AIX 3.2, so we patched the telnetd(1) to execute "/bin/fubar"
instead of "/bin/login".  The program "/bin/fubar" starts the application
(our University's course registration system).

Everything works fine, except for one annoying thing.  When using
"LAN Workplace for DOS", the TELNET negotiation to the RS/6000 gets confused
and both systems want to echo.  When the user types something and hits
return, the text is echoed.  This doesn't happen when we use telnet(1)
from other RS/6000s, SGIs, Suns, etc.

What could be the problem?

News-Software: VAX/VMS VNEWS 1.41    
Organization: Vanderbilt University
Date: Tue, 3 Nov 1992 20:54:00 GMT

I am using two model 340's that were separetly configured. They are connected
to the network via thin ethernet lines. In the same environment we also have
a 320H machine. There are 6-8 X-stations tied to these machines. They are all
at 3.2.2 or higher level.

On both of the 340s while typing in a window we get pauses of the blip while
one keeps typing. Then the buffer is suddenly flushed. I have only seen this
with the X-stations but someone told me that it also happens on the console.
It is very annoying. I have a 320H which is working perfectly. It almost
behaves like packets being dropped during the transmission. I noticed that
320 has the Hi Perf ethernet adapter at ros level 28, whereas the 340's have
something called the standard ethernet adapter. The lscfg -v -l ent0 command
does not produce anything but the title line on the 340s whereas it
produced detailed info like ros, fru, serial number etc on the 320.

Is anyone aware of such problems or solutions?

Indeed, all mail here is delivered through a central machine running
BSD, and it works fine.

Well, almost.  Since the "central machine" in question has an even more
losing NFS implementation than average, locking doesn't work, and all
the mail readers have to be configure to use `.lock' files.
Unfortunately, *since I don't have source*, I can't do this very easily
to the standard mail readers, except by simply installing the BSD code.

Just like other Unix implementations, AIX differs in a variety of
ways from the 'standard' (whatever that is nowadays).  I would like
to hear from some AIX folk on the following questions, and would
be most appreciative of any feedback resultant:

+ How does AIX differ from SVR4?  SunOS?  HP-UX?  BSD4.3?

+ What has IBM added that makes AIX *better* than other Unixes?

+ What has IBM added that makes AIX *worse* than other Unixes?

+ Is source from the net easily ported onto the AIX platform?  And are
  programs written for the AIX system portable?

+ What about X, and Motif?  Are they standard and compatible?  What
  version of X11 is with the existing version of AIX?

+ What do you think of "smit"?  What about the rest of the system
  administration tools?  

+ If you could change one thing in the AIX OS, what would it be and why?

+ If there was one thing in AIX that you'd like to migrate to the rest
  of the Unix industry, what would it be?

+ IBM touts the SAA connectivity and ability for the AIX systems to
  plug right into existing IBM networks, mainframe and otherwise.
  Have you found that true?  

+ What about the RS/6000 series?  What are your thoughts about it,
  how did you come to the decision to purchase it, and how do you
  think it compares to other workstations from Sun, HP, DEC, etc?

+ If you had it all to do again, would you buy another IBM RISC
  workstation with AIX?

+ Finally, whatever happened to NeXTstep on AIX, and what do you
  think about it, PowerPC, and perhaps the possibility of Windows
  NT on the RS platform?

THANKS GREATLY for your assistance on this: if you're interested in
a summary of the answers to this question, just note as such in your

Having serious trouble getting R5 xdm to work with AIX 3.2 on the console
display running IBM's R4 server.  I haven't tried it with XStations yet,
but I suspect it would work.

The problem is that the X server "dies unexpectedly" several times and
then xdm quits trying.

Installing the BSD 4.4 netwoking patch to XConnDis.c does not solve the
problem.  I suspect this patch is useful only if one is using the R5
server (which we're not).

Hi:

Does anyone in know of a public domain version of pstat for 
AIX 3.2?  I basically need to extract the following from an
AIX kernel:
	maximum number of files the kernel supports (nfiles in SUN)
	maximum number of inodes (ninode in SUN)
	"shminfo" structure -- shared memory information structure
	"seminfo" structure -- semaphore information structure
I can do an nlist(3) on /unix and get offsets for the shminfo, and seminfo
variables. However if I then try to extract them from /dev/kmem using
lseek and read I get nothing. Are there special kernel seek/read calls in
AIX 3.2?  (i.e. like kvm_read() in SUN??)

I have the 1.05 version of the pd monitor program but this doesnt look for
the variables I look for. In addition, the monitor program uses knlist(3)
which must be different that the nlist(3) function (how or why??).

Any comments would be *GREATLY* appreciated.

Hmm.. I dunno. From where *I* am, knowing that the vendor cares enough to
ship me another patch tape every 2 months improves my confidence.

I've never heard MVS flagged as a "buggy" operating system - but IBM was
shipping a PUT tape *EVERY MONTH* for about 20 years (Consider that OS/360
finally stabilized at MVT 21.8F or so - that's a *lot* of update tapes),
and I was still getting monthly PUT tapes for our OS/VS1 system in 1989 -
for a operating system announced in 1972.

Of course, by 1987 or so, the VS/1 update tapes only had a *new* bugfix
on them every 2-3 months - and it would be some obscure thing that
would only bite on rare occasions at some sites.

Now, if you want to talk about the fact that the monthly update tapes
have *too many* fixes on them to be confident, that's a DIFFERENT
issue... ;)

[A medieval buff puts his armour on <|O ] 

Excuse me!?  Am I missing something here on the v3.2 remark?  In the
10+ years of dealing with UN*X and other OSs with virtual memory (VM),
VM was always RAM and swap space **TOGETHER** (ignoring demand
paging).  Now unless IBM has come up with a new trick, how are we
going to sleep and swap a process if VM (and therefore swap space) was
running low.  The way I would figure it, that is like saying that "I
am bleeding from a wound, I'll shoot myself to cure it".  The method
is used by many VM swappers to free up RAM for processes.

Now here is one for thought...look for an executable that is swapped, flush
the text from the swap space (since it is supposedly read-only, and therefore
reproducable), and then mark the pages as not having been loaded.  After that,
leave it to demand paging to pull it back in again.  Then you can think of it
as a secondary swap with larger overhead. 8)

The ptrace allows me to read/write bytes in anothes process's address
space but it will not allow me to use the 'read' system call with
an address in the other process's address space as an argument without
copying the data into my own address space first. As the amount of data
is HUGE this would be an incredible wastfull operation....

What I want to do is :

     .
     .
     map process B's address space to my address space at addr N
     write(fd,N,n_bytes);
     .
     .
     read(fd,N,n_bytes);
     .
     .

such that the read/write operation goes directly into process B's 
address space.
