[comp.sys.ncr] shadow passwd in Tower 500 OS 1.01.02

art@bohtsg.pegasus.com (Art Neilson) (06/22/91)

I recently tried to implement shadow passwords in our Tower 500
OS 1.01.02.  Everything seems to work fine except for va.  /bin/login,
/bin/su and other system utilities behave correctly in the presence
of /etc/shadow.  /bin/passwd correctly updates /etc/shadow with new
passwords, and /bin/login looks up passwords in /etc/shadow instead of
/etc/passwd as does /bin/su.  Unfortunately /va/obj/va which is invoked
by /va/obj/vastart (va's login shell) detects the presence of /etc/shadow
and complains that you must remove the shadow password option before
va will work.  Why is va crippled in this regard ?  We are a Banking
Institution and would like to implement the shadow feature to enhance
security.  The old sa administration system was composed of shell scripts
so it is easy to modify, however the new va administration system is a
binary file and cannot be easily modified.  We really liked the old
menu system and the ease of adding our own custom Banking menus to the
standard sa menu system.  This is no longer the case, we haven't a clue
as to how one can hook into the va menu system.

We have va on a 450/32 Unix 3.00.01. It is hard to give up the sa stuff.
We brought a lot of it over when we migrated; but any new applications
would be hard to figure out what to do. I got the va manuals and tape
for installation from NCR; but it looked kinda foreign and I have never
gotten into it.

Did it come from ATT?
What was(is) the point? sa was pretty good I thought.
Do any 3rd party software vendors supply va installable product, or is it
	an NCR exclusive?
Do the 3000 machines use va? is it part of V.4?
Would va give me a head start in any later migration?

Both sa and va are NCR products.
Va has all kinds of rubbish like reverse fields, windowscopes and other
childish stuff, that obviously charmed some Manager, who desparetly
needs a promotion to some island in the Pacific.
Indeed, sa was far more transparent than va and better managable.
It also *worked* fine. After a few years, va still suffers from
bugs like not restoring the generated keycodes after operation etc.
Also, the logic is very dumb and slow.
The #$%^ with va, give us sa back!!

Heh.  It turns out that /va/obj/ofinterpret is the guilty party, he
checks for the existence of the file /etc/shadow, displays an error
message and exits if it is found.  It's easy to use a hex editor and
search for the ascii string "/etc/shadow" in the ofinterpret binary,
once located set all 11 bytes to binary zeroes.  This will allow
va to run in the presence of /etc/shadow.  The system utilities such
as /bin/login, /bin/su and /bin/passwd already know what to do with
the shadow file, you just have to create it.  It should be easy to
create an awk script to automate the migration task.  I now have the
undocumented shadow password option running fine on our Tower 500
OS 1.xx in spite of va.

WRONG!  sa menus are added by Unisys on their version of the NCR release.

Let me try to put this issue to bed, once and for all.

NCR designed and wrote both SA and VA.  Neither AT&T or Unisys were
parties to the original design.

Unisys purchased the TOWER and modified the OS (including SA/VA) for
their own purposes.

System 3000 products do not have SA/VA menus; rather, NCR delivers
the AT&T SVR4 "sysadmin" subsystem as a replacement.

If that's the case, why does my Tower XP have sa?

    Say what!  We may be talking about two different implementations of
    an sa environment, but NCR had sa on the original Tower 1632, and I
    believe the shell scripts for sa all had NCR copyright notices.  To
    my knowledge, the sa that ran on the earlier versions of the Tower 
    OS where all developed by NCR.

Then why did every NCR Tower I ever managed while at NCR have the SA
menus before the release of VA? Get a clue, Craig.

I do agree with comments regarding SA/VA. SA was straightforward, seemed
to have a nice tree structure, and about the only negative thing I
could say about was that it just loved every opportunity to retension
a streaming tape. I ended up going in and disabling a lot of the
retensioning just so tape operations would finish in finite time.

VA, while sort of pretty, always messed up my terminal, a bunch of the
fumctions led to non-existant executables (mostly related to TCP/IP
setup), and there were things I wanted to do in VA that didn't seem to
exist.

On the subject of the sysadmin menus from AT&T, unless they've been
enhanced a lot from what they were in V.3.2, they are way underpowered,
at least that's true of what ISC ships. Hopefully NCR has enhanced
the functionality to step the admin through a lot of the messy
hardware configuration and maint. type jobs.

Unisys sa and NCR sa are not the same. Unisys does add their own, but it
replaces the NCR package rather than augments it.
