I find that (on IBM RT's, PS/2's, and RS6000's) IBM tends to make
their software so that it's easy to connect with other IBM machines,
but it's extremely painful to connect to anything else!

YP (NIS), sendmail, NFS, etc. seem to work ok between our two RT's,
but it took a major struggle and lots of options to get this stuff to
work between the RT's and Suns.

And simple programs like "install" don't work right on the RS6000.
All of my favorite switches like -o, -g, -m have been changed to
upper case.  Now, I'm sure these some mode or path somewhere you can
set to get the real install, but if you login to one of these systems
with simple program source and type "make install", it won't!

Sure, each OS has its peculiarities.  I just find that AIX 3 seems to
be too different in some of the *basic* programs (like install).
I've had nothing but bad luck with the pre-releases OS's crashing the
system, and now that at a fairly stable OS is out, I can't just bring
my local software over without lots of pains.

If I was still a sysadmin with a Computer Science Department, I'm sure
I'd enjoy all of the neat new things like the access control lists and
the hypercard libraries and such, and my users would probably be just
as interested.

But being with the Geography Department, I'm just interested in getting
a system up so that my users can get some work done.  My users just
want a machine to help them with research.  They don't want to have to
deal with all of these problems on a daily basis.

I've put on my Big Blue Asbestos underwear.  If you're going to flame,
please just send mail to me.  I'll "summarize" to the net ;-)

Hmmmm.  I can't speak for YP/NFS, but in the tcp/ip group we've had few
problems with interconnection.  Judging from the sorts of problems reported
in the tcp/ip and sendmail newsgroups, AIX seems to have less than its
share of inter-vendor connectivity problems in these areas.

Since the majority of our tcp/ip and mail code is straight BSD tahoe ports,
I don't find this too surprising.

I would, however, be interested to hear precisely what sorts of problems
you've had.  Please respond by email unless you consider them of global
interest.

	sendmail.cf files seldom, if ever, drop out of the box and work.  IBM
tried to make it so that you wouldn't have to change much, but anyone who has
anything other than a generic setup shouldn't be too surprised if they have to
install a new sendmail.cf file.

	Well, /usr/ucb/install has everything you're asking for.  As a rule, 
if you used BSD or BSD-derived systems before, and that's what you want from 
your RISC System/6000 (RS/6000), then ALWAYS put /usr/ucb first in your path.
That's what all of us "BSD-bigots" here do. :-)

	Again, most of the major programs that have incompatibilities have BSD
versions in /usr/ucb that should behave just the way you (and I) are used to.

	Put /usr/ucb in the first position on their paths and they won't have
to worry about it.  I'm not saying this will solve 100% of your problems, but
it should go a long way towards it.

    All the world's not a VAX (though AIX executables do have
    zeros at address 0), and there's no one, true UNIX that
    all good implementations must slavishly follow.

    The changes were made to avert conflicts with flags used by
    System V versions of install.  If they hadn't been made,
    some System V users would be complaining just as loudly.

    install is a basic program?  I usually use cp or mv instead;
    they're more portable, and install is inexcusably slow on
    some systems.

    I don't recall whether they've been mentioned here before, but IBM
    has made available two guides to AIX 3.1 for 4.3 BSD users.
    They're called `AIXv3 for 4.3 BSD System Administrators' and
    `Porting 4.3 BSD Programs to AIX Version 3.1'.  They're a bit big
    (100K and 65K, respectively), but if there's enough interest it
    might be worthwhile to split them up and post them.

Those with Internet access can use anonymous ftp to obtain
these documents from vmd.cso.uiuc.edu (128.174.5.98)
cd to directory SHAIR.3CC and get the files bsdportx.tr and
bsdadmx.tr.  They're text documents which are to be processed
by troff to print, use "me" macros.

We ran into a neat one yesterday.  If your root shell is /bin/ksh (the
default) and a user's home directory is NFS mounted (most of our users
are on a Sun-4/330 under 4.0.3c) and the user "su"'s to root, ksh will
start making tons of NFS requests across the network.  It will flood
the network, thus inhibiting everyone's communication, and bring the
foreign server to its knees (biod's will be running all-out).

Killing the ksh process started by "su" causes the problem to go away.
Changing the root shell to /bin/csh eliminates it entirely.

This problem exists under 9021F with the 3001 update installed.  We
never noticed it before the 3001 update so I believe the update caused
the problem (might be wrong though).

This problem has been reported to IBM.
