Titolo: [Fwd: [multidesk] Fwd: Re: Unix-like enviroment for OS/2?]


We considered this in our design and have provided facilities to enable
the delivery of a custom and separate desktop to each *local* user. The
user's defined shell is started at logon and stopped at logoff. This is
true for the WPS as well as other user-defined shells. They are all just
treated as processes that run in the context of a specific user's logon.
We allow each user to have a different set of shell definitions and
custom
configuration that goes with their chosen shell.
However, there are some caveats:
1. If you are not using the WPS, you may use any PM program as your
shell. We fully support this and have tested it. We also have a simple
mechanism to pass data via the environment and/or command line to that
shell to allow it to obtain user specific configuration data at launch
time.
2. If you do use the WPS, you can have a custom \DESKTOP directory tree
and OS2.INI for each user. Our limited testing has shown this to be
problematic and we think it is due to mismatches in between the DESKTOP
EAs and some contents in OS2.INI. We have not yet had a successful test
of this and so there may be other problems, as yet undiscovered. However
we believe that it is possible and that our system is already coded to
handle this. The issue may only be in the implementation (creating such
matching desktop directories and INI files may require a tool or at the
very least a known process to make it practical).
3. The OS2SYS.INI is defined at IPL time (in CONFIG.SYS) and cannot be
switched while booting. IBM's design point was to make this file
system-wide. Note that any information (like the many printer-related
definitions) that exist in this file cannot be easily managed through
the
above listed mechanism. This may limit the user-specific WPS swapping
because the WPS does seem to store some data (like lists of object
handles) in this file. More testing will be necessary to determine what
limitations exist due to this restriction. I don't recall where font
palettes are stored, so this may be a problem.
We do ship a program that provides launching/switching capabilities.
This
is suitable for use as a user shell and functionally provides everything
that most users may ever need. This is fully tested to work in this
environment and each user does get a custom "desktop". But in this case
the WPS is not the primary user shell.
We have a version 1.0 release candidate and are undergoing testing, code
review and bug fixes as necessary. It has some known limitations
(security holes, if you will) that are due to design choices made by IBM
in their design of OS/2 and their security enabling subsystem (SES). So,
before we publicly release this technology, we will be working on
solutions that eliminate these gaps and provide the capability of having
a
complete solution. This is be a v1.1 of our software and it is this
version that will be generally available. We can and will work with
selected clients to test/evaluate our v1.0 product and use this feedback
to improve the software. However, this list of clients has not yet been
determined.
I can't really do justice to the technology in an email, but I hope you
have gotten an idea about its capabilities. There are many features and
functions that can be added, but our first public delivery will be a
substantial security system in its own right.
Let me know if there are any questions.
Thanks,

Non lo so , questo e' un forward di un messaggio nella mailing list di
Multidesk di Cristiano Guadagnino, prova a scrivere a lui senz'altro ne
sapra' di piu'

Speriamo bene, e speriamo che per la sicurezza non si riferisca solo al
controllo accessi tramite WPS...

 vedo male.
Scusa ma la WPS si appoggia ad os2.ini ed e' il PM che si appoggia ad
os2sys.ini quindi se si riesce a trovare un sistema per riavviare il PM
si potrebbe anche trovare il modo che usi un diverso os2sys.ini...
vabbe' la cosa non e' automatica ma non piu' difficile che riavviare il
PM... imho.

kernel in poi?
Lui parla di controllo degli accessi ai file. Speriamo intenda anche
tramite API e non solo tramite finestrelle.

molto pesantemente ovunque; specie nell'architettura del kernel...
