All,
The results of my PDP-11 UNIX source license quiz so far are
available on the PUPS web page, http://minnie.cs.adfa.oz.au/PUPS/
If you haven't filled out the questionnnaire, please do so, as it
gives me more ammunition to convince SCO to make licenses available.
Get your friends, family & household pets to fill it out too :-)
Most of the results were as I expected, although less people were
happy with the single-user idea that I thought would be.
Cheers,
Warren

This notice is being posted today in relevant Usenet conferences.
Thanks for your help in reaching a major milestone!
Computer History Simulators V2.2d: Release Notes
V2.2d is a major release of the simulators for the Computer History
project. It includes simulators for:
- Data General Nova
- Digital Equipment Corporation PDP-8
- Digital Equipment Corporation PDP-11
- Digital Equipment Corporation 18b PDP's
(PDP-4, PDP-7, PDP-9, PDP-15)
- IBM 1401
These simulators are freeware. They are intended for personal or
educational use and are provided on an as-is basis. Support is not
available, and commercial use is prohibited. See the documentation
for debug status for each simulator.
This release also includes demonstration software for the PDP-8,
PDP-11, and Nova:
- RDOS V7.5 for the Nova
- OS/8 for the PDP-8
- UNIX V5, V6, and V7 for the PDP-11
The demonstration software is provided for personal, non-commercial
use, under license from its current owners (Data General for RDOS,
Digital Equipment Corporation for OS/8, and the Santa Cruz Operation
for UNIX). Please be sure to read the license agreements before using
or distributing the demonstration software. A copy of the appropriate
license agreement(s) must be included with any copy of the
demonstration software. I gratefully acknowledge the generous help
and support of Data General Corporation, Digital Equipment
Corporation, and the Santa Cruz Organization in making the
demonstration software and supporting license agreements available.
The simulator sources and documentation are contained in a compressed
tar archive on the public FTP server ftp.digital.com:
/pub/DEC/sim/sources/sim_2.2d.tar.Z
The simulators have been tested under Digital UNIX, VAX VMS, Alpha
VMS, and Intel Linux. A port to Windows 95/Windows NT is underway.
Porting to other little-endian UNIX systems is straightforward, but
porting to big-endian systems is not: data representations are endian
dependent.
The demonstration software and licenses are contained in multiple
compressed tar archives on the public FTP server ftp.digital.com:
/pub/DEC/sim/software/rdosswre.tar.Z - RDOS
/pub/DEC/sim/software/os8swre.tar.Z - OS/8
/pub/DEC/sim/software/uv5swre.tar.Z - UNIX V5
/pub/DEC/sim/software/uv6swre.tar.Z - UNIX V6
/pub/DEC/sim/software/uv7swre.tar.Z - UNIX V7
(Very) cursory instructions for using the demonstration software are
included in the simulator documentation.
The simulator project includes many contributions. For a more
detailed description of the simulator itself, and the many people who
helped with it, please see the (forthcoming) December 96 issue of the
Digital Technical Journal, which has an article on "Restoring Old
Computers" by Max Burnet and Bob Supnik.
YOU can contribute to the computer history project! The simulator is
an open-ended framework, and contributions are welcome, such as:
- further debuging of the existing simulators
- additional peripherals for existing simulators
- new software images for existing simulators
- new simulators
- terminal emulation routines for Windows 95/Windows NT
- ports to other operating environments
Please send your contributions to bob.supnik at ljo.dec.com.

I got somehow a M70>-Prompt (after a @-Prompt) and booted it with DU<Return>.
Can I make somehow a bootable floppy-backup?
Is it supported by V7 or another UNIX?
How big is the harddisk?
What device/size is the floppy? DK?
Is it possible to read/write these floppies with a PC?
Is it possible to make UNIX-boot/install-floppies with an emulator
and install with the UNIX on this PDP-11?
What did I forget to ask?
Thanks

Warren,
I have a Micro-PDP 11/73 running 2_11BSD now, and a running 11/23+
system that I'd like to find a Unix for (currently it's running RT). The
11/23 lacks I&D space and therefore is unable to run 2_11BSD, and also
it's severely handicapped because its largest disk a RL02.
I also have a several other DEC non-Unix systems including a 11/730, a
PDP-8/A, and too many VAXstation-2000s and 3100s to count. All run
perfectly except the -8, which is my current project.
I have a some UNIBUS and QBUS spares, and even a few OMNIBUS parts, and
I'm always willing to trade with other collectors.
I'm afraid I know very little about Unix, but I do have some experience
with DEC hardware and would be happy to try and help out in this area.
Please do not reply to this account - my home email address is
bob at poco-adagio.santa-clara.ca.us
Thanks,
Bob Armstrong

Hello Warren,
My name is Don.
I visited your webpage today about the "PDP-11 UNIX Preservation Society".
Although I'm not inclined to participate, I am however the proud owner of a
DEC PDP-11/04. It is complete except for a dumb terminal/ keyboard. It is
mounted in two 6 1/2 foot tall steel racks it includes a dual 8" floppy
drives with unopened boxes of new 8" disks, one 12" cartridge removable
hard drive with 6 cartridges, one 12" reel to reel mass storage tape drive,
power supply, supportive hardware and all cabling. Also there is an 18"
medium speed drum printer in a sound proof encloser. No it's not for sale.
However, I would like to give it away. Obviously it is very heavy and
there is no way I could ship it. I would like to know if there is a member
of this Society somewhere in the mid-west ( close to St. Louis,
Missouri,USA ) that might be interested in having it just for coming to get
it? The unit was fully functional when I removed the dumb terminal to use
in another application, so it's not just "junk".
This unit is mine and not property of the University that I'm affiliated with.
I hope this may serve a common interest.
Thanks
Don.

I just wanted to share an interesting experience that might save
someone else some time if the occasion should arise...
I've got a Q4 cabinet with two BA23s in the middle, an RA81 below them
and a TS05 tape station on top. It's had a KA630 (a MicroVAX II, that
is) CPU running VAX/VMS, Ultrix and 4.3BSD-Reno before, and the TS05
has always behaved perfectly. Just recently, I reconfigured this box
with a MicroPDP-11/73 (a great little system: two RD54s, twin RX50s,
TK50 and TS05, DELQA, DHQ11 and the RA81), and was dismayed to find
that my trusty old 9 track tape station no longer worked!
After several, unsuccessful attempts to get some (too) old diagnostic
software to work, I put the KA630 back in, and ran MDM, the MicroVAX
Diagnostic Monitor. The tape station checked out perfectly. Back in
went the 11/73 -- sure enough, it didn't work. Experimenting showed
that I could fsf, bsf rewind and stat the tape station with mt all I
wanted, but I couldn't read nor write. The controller always gave an
illegal address error, which the manual says is what happens when you
use it in a 22 bit qbus while it's configured for 18 bit operation.
Of course, that couldn't be for real, right? I mean, the KA630 is a
22 bit system, and it worked on that with several operating systems!
Still, it doesn't hurt to check, so I pulled the controller. Yup, it
was set to 18 bit mode. Flipped it to 22, turned on buffering at the
same time -- and I now have a fast, dependable 1600bpi 9 track again!
If anyone can explain how this thing worked in the first place, I'd
appreciate it! (Oh, and if anyone has some hints for this youngster
about the proper care and feeding of my TS05 as the years go by, that
would come in very handy as well!) (Heck, while I'm asking all this,
an RK05 with qbus controller and a few packs would be great, too, and
would go real well with this old /23 I've got sitting here!)

As far as I can see, you can do anything with the disk image as long as
it's non-commercial. So I'm sure that it's perfectly legal.

Bob, firstly if you can write down the details of how you got the
image installed & running on the 23+, and email it to the mailing list
(oldunix at minnie.cs.adfa.oz.au), that'd be great, as I archive the mail.
Secondly, I'm unsure of the copyright/legal status of the man pages.
It would be good if they could be released publically. I might ask Bob
Supnik if he has any ideas.
Finally, many of the members of the PUPS mail list are covered by
source code licenses, so if you can tell us what device you require,
I'm sure someone can build a kernel for you. I wonder if it's legal to
ship a kernel which has device drivers not in Bob Supnik's disk image?!
Hope so!
Cheers,
Warren

THat was my impression too, Neil. I was being hopeful (as always). We do
need to talk with SCO (via Bob Supnik?) to ensure we have SCO's permission
first.

Great ! Finally gotta dig out that old RL02 drive ... How did you manage
to get the image onto the RL02 ?

Some time ago, the 7th Edition man pages were available on
http://plan9.att.com. This machine currently seems to be down, so I can't
verify if the man pages are still there.

It was actually quite simple. Bob Supnik's RL02 file is simply a byte
for byte dump of a pack. That is, it's just sector 0, head 0, cylinder 0
followed by sector 1, head 0, cylinder 0, ... then all the sectors of
head 1, cylinder 0, then cylinder 1, etc. There are no overhead bytes
in the file an no interleaving is used. RL02s have 40 sectors of 256
bytes each per track, two heads, and 512 cylinders for a total 10240K bytes
per disk (which happens to be exactly the size of Bob's RL02 file :-)
You want to be careful about bad sectors, since RL02s do bad block
replacement at the device driver level. If your pack has any bad sectors
that aren't at exactly the same spot as bad sectors on Bob's original
pack (not very likely!), then this isn't going to work. Fortunately
error free RL02 packs are relatively easy to come by.
Anyway, since the only other RL02 that I have access to is on a VMS
system, I had to write a little program for VMS to load the disk using
physical I/O. I'd be happy to make this program available if anyone
wants it.
Once you have the pack loaded, you can just mount it on a 11/23 and use
the RL02 hardware boostrap. The Unix boot will start and print a "@" for
a prompt. Reply by entering "unix" and carriage return, and you'll see
"mem=205376" followed by "SINGLE USER LOGIN:". Enter ^Z and Unix will
start timesharing, then you can login in using root with the password "pdp".
I had two problems in this process. First, I didn't know about the
Unix bootstrap program (I'm afraid I've never used Bob's emulator!), and
when I saw the "@" I just blindly assumed I'd been dumped back into ODT.
Fortunately Jim Carpenter was kind enough to educate me about this.
Second, Unix would hang up as soon as I started timesharing. This
turned out to be because my LTC in the 11/23 wasn't working, which doesn't
bother RT11 at all but it does hang Unix. After I repaired the hardware
everything ran fine.
If someone has a PDP-11 with a RL02 drive and no way to load V7 on a
pack, I am willing to do it if you send me a blank RL02. I believe the
SCO license allows this so long as:
1) I don't charge for the service
2) You certify that it is for non-commerical use
3) I include a printed copy of SCO's license
Note that this kernel supports only RL02 drives, so unless your -11
has a RL02 drive this system won't work. RD5x and RA8x drives won't do.
A similar procedure would probably work with the RK05 images, but I
don't have the hardware to try.
>Finally, many of the members of the PUPS mail list are covered by
>source code licenses, so if you can tell us what device you require,
I have a 11/23, DLV11J (4 lines), RL02/RLV11, TU58 (on one of the
DLV11 ports), RX02/RXV21, and a TSV05 9-track tape. The TSV05 is
TS11 compatible, and I'd especially like to have support for it.
Bob's kernel supports MASSBUS tapes, but not a TS11.
>I'm sure someone can build a kernel for you. I wonder if it's legal to
>ship a kernel which has device drivers not in Bob Supnik's disk image?!
SCO's license seems to cover all PDP-11 binaries for 7th Edition Unix,
and it doesn't seem to say anything about their origin. Of course,
I'm not a lawyer either.

Ok, I'd try to chat with the person before they leave! At least to get the
root password.
I am cc'ing this email to a group of PDP-11 Unix users who may be able to
help you out. I'd guess it's a 6th or 7th Edition UNIX, or a 2BSD system.
What you really need to know is:
+ how to get a root login on the system
+ how to change the root password
+ how to reboot the system properly
If the person leaves root logged in on the console, at least you can
type passwd and change the root password. If they haven't, then there
is no easy way of getting a root login to change the password, except
for rebooting the system.
Rebooting depends on what PDP-11 you've got there. If you can find out,
someone here should be able to explain how to boot into single-user mode,
where you have a root prompt and can change the root password and then
go to multi-user mode.
I'll try to get the basic maintenance manuals for these old UNIX systems
put into ASCII and email them to you.
Cheers,
Warren

Hi, Warren!
I've written a CSR and vector calculator, based on VMS documentation
and comparison tested against VMS SYSGEN. For want of a better name,
I'm simply calling the program 'sysgen' -- this shows its heritage, at
least... :-)
This should be useful to PDP (and VAX) users who don't have a VMS
system handy, and would like to configure their systems according to
DEC standard. Would you add it to the PUPS archives and send out an
announcement to the mailing list, please?
Thanks!

Dear PDP-11 Unix people,
I'm emailing you because I haven't done much in the last few months about
encouraging SCO to sell source licenses for PDP-11 UNIX, and I think it's
time we try a new tack.
The person I've been negotiating with a SCO is Dion Johnson, dionj at sco.com.
I pestered him a lot last year and so perhaps I've worn out my welcome with
him. So I'd like to suggest another approach or two.
Perhaps another person interested in PDP-11 UNIX source licenses can try
talking with Dion or other people at SCO? Any volunteers? Steven Schultz?
Bob Supnik? Alternatively, if nobody comes forward, we could all email Dion
expressing our desires for sources licenses for these old UNIX versions.
Looking at the survey I've been conducting at
http://minnie.cs.adfa.oz.au/PUPS/, at least 130 people are interested in
source licenses, and the general consensus is:
No resale of license is acceptable
No source redistribution is acceptable
50/50 split on single-user-only licenses
No commercial usage is acceptable
Full source code is preferable
Main UNIXes to be covered are 5th,6th,7th Edition and 2BSD.
Cost of license no more than US$200, max.
After reviewing the email from Dion, I'd add another condition which
would make SCO happy:
Source license adequately protects SCO's intellectual property,
in their view.
Anyway, please email your suggestions on what we should do to the PUPS
mailing list (oldunix at minnie.cs.adfa.oz.au) or to me. I think the single
person approach is better than flooding Dion with email. Maybe we can sign
an email petition and deliver that to a number of people at SCO?
Thanks in advance for your input!

Dear PDP-11 UNIX people,
The small response to my suggestions about lobbying SCO for source
licenses brought some volunteers for the cause, and a preference for a
single petition to SCO rather than mail-bombing :-) If you didn't respond,
please let me know what you think & if you're willing to help out.
I've written a draft petition, which is attached below, and is also
available (with some hyperlinks) at
http://minnie.cs.adfa.oz.au/PUPS/petition.html
Is there anything in the draft you disagree with, or wish to change?
Please let me know!!

The Santa Cruz Operation, Inc.
Dear Sirs/Madams,
We, the undersigned, are a group of people who are interested in obtaining
source code and binary copies of the versions of UNIX that ran on the PDP-11
range of computers from Digital Equipment Corporation. We would like to
have copies of these versions of UNIX because:
+ they are of great historical importance, and/or
+ we personally own PDP-11 computers on which these systems will run.
The Santa Cruz Operation, Inc. owns the copyright to these very old versions
of UNIX. We understand and appreciate that SCO wishes to protect their
intellectual property within, and ownership of, these versions of UNIX.
Therefore, we wish to petition SCO to make available source code and binary
licenses of these versions of UNIX so that:
+ we can legally own source code and binaries for PDP-11 UNIXes, and
+ SCO's copyright and intellectual property is protected.
We would be happy to purchase and be legally bound by a source code and
binary license for PDP-11 UNIXes that meets SCO's requirements, as long as:
+ the license covers the entire distributions (source code, binaries
and documentation) of the following versions of UNIX:
- 1st, 2nd, 3rd, 4th, 5th, 6th and 7th Edition UNIX
- 32V UNIX
- PWB/UNIX
- those portions of all 2BSD releases which are derived
from UNIX source code
+ we have the right to make changes to the source code of the
above versions of UNIX
+ we have the right to distribute our changes to other people who
have signed and agreed to the source code and binary license for
PDP-11 UNIXes
+ we have the right to install UNIX binaries on PDP-11 hardware
and PDP-11 emulating software
+ we have the right to allow other people to use the UNIX binaries
on such an installation
Note that the latter is already permitted, given SCO's binary license agreement
for 5th, 6th and 7th Edition UNIX. We would also be happy with the following
conditions imposed in the source code and binary license for PDP-11 UNIXes:
+ no resale of the license is permitted
+ source code covered by the license cannot be distributed or
disclosed to people not covered by the license
+ no commercial usage of the source code or binaries is permitted
+ SCO is not required to include copies of any source code, binaries
or documentation with the source code and binary license for PDP-11
UNIXes
On a recent survey of people interested in such a license (see
http://minnie.cs.adfa.oz.au/PUPS/), over 120 people responded. Most of
the respondents would agree to a license with the conditions and limitations
outlined above, if the cost of such a license was less than US$200.
We urge you to consider
+ the historical significance of the UNIX operating system,
+ that the PDP-11 versions of UNIX are essentially obsolete,
+ that superior UNIX-like operating systems, libraries and
applications are freely available in source code form,
+ that the source code to 6th Edition UNIX is publically available
in printed form (Lion's Commentary on 6th Edition UNIX, Peer to
Peer Communications, Inc.)
and make personal-use non-disclosure source code and binaries licenses
for PDP-11 UNIXes available at a price which we can afford as individuals.
The UNIX community has played an extremely important role in the development
and success of the UNIX operating system. The Santa Cruz Operation, Inc., as
owners of the UNIX operating system source, would be repaying the UNIX
community in some measure by providing source licenses for these old versions
of UNIX. Although you would not profit greatly from the licenses, you would
earn the respect and appreciation from many people who helped make UNIX what
it is today.
Thank you for your time. Your response to our petition will be appreciated,
and can be sent via Internet e-mail to Warren Toomey wkt at cs.adfa.oz.au.
Sincerely yours,
The undersigned

Hi Colin, I saw you sign the petition, thanks. The problem is how to load the
software onto the box! There are RK05 disk images of UNIX (v6 and v7) at
ftp://minnie.adfa.oz.au/pub/PDP-11-sims/Supnik_2.2d/
But how do we get them into the box? Do you have any boot disks for any OS
(RSX, RT-11)? What about tape drives?
I'll pass this onto our mailing list, maybe some more knowledgeable readers
will be able to answer you. Alternatively, posting this to vmsnet.pdp-11
should get you an answers.

Subject: Petition SCO for PDP-11 UNIX Source Licenses
Hello,
You may have received email from me last week asking for ideas about
lobbying SCO to make source licenses for PDP-11 UNIXes available. The feedback
from the email was in favour of creating a petition which we would present to
SCO. I mailed a draft petition to many of you and again got a favourable
response.
Therefore, I've set up a WWW petition for PDP-11 UNIX source licenses at
http://minnie.cs.adfa.oz.au/PUPS/petition.html.
PLEASE SIGN THE PETITION!!! if you agree with the petition.
PLEASE GET OTHER PEOPLE TO SIGN TOO!!! We need as many signatures as we can
get. Pass the word around to other interested people you know of.
If you filled in the PDP-11 UNIX source code survey on the same WWW server,
your name has been automatically put on the petition, unless you disagreed
with the petition's contents. Please email me if you want your name removed.
You can re-sign the petition to add your Full Name; I'll tidy it up later.
I'd like to get well over 100 names on the petition before I pass it to SCO.
If you have contacts at SCO who we could send the petition, please email me!
If you'd like to be put on a mailing list to be kept informed of the petition's
progress, also email me.
Hopefully, we will get a result from SCO.
Thanks again,

Apologies if you've already got word of this; I've lost track of who I have
& haven't emailed. There is a petition to sign to convince SCO to make
Unix source licenses available at

160 signatures so far, about 120 culled from the survey I was running and
40 in the past 48 hours. Please sign if you want SCO to make licenses
available!
Informal feedback from SCO is good; Dion Johnson there thinks it looks
reasonable & he will be our advocate at SCO.

Hi all,
I've just tracked down another old tape with PDP-11 Unix stuff on it.
It's in the UK. Anybody there care to chat with George & extract the bits
from the tape so we can put it in the archive?

Warren,
I've had a 9-track tape reel in my bottom drawer for about 15 years. I no
longer remember what is on it! It may contain the source of 'em' and a few
other utilities that I wrote in the '70s. Unfortunately I have no
convenient way to read it. If you are interested, I could try to find
someone with a 9-track reel drive, or if you have one I could just
send the tape to you. I'd be happy to liase with anyone who is willing to
have a go at reading the tape.
George
----- End of forwarded message from George Coulouris -----
Also, the source code petition has now got 290 signatures. I haven't heard
anything from SCO since I passed it to them formally, except that they had
received it and it was being passed to `the right people'. I'll keep updating
the status page, hyperlinked to the petition itself, as things happen.
The petition's at http://minnie.cs.adfa.oz.au/PUPS/petition.html. Quite a
number of well-known people have signed. Both Andy Tan(n)enbaums, Steven
Schultz, Richard Tobin, Bill Joy, Henry Spencer, Neil Groundwater, Dave
Presotto, Andrew Hume, Peter Collinson, Greg Rose, Brian Redman, Peter
Honeyman, Megan Gentry, Jim McKie, Margo Seltzer, John Mashey, Peter Salus,
Ozalp Babaoglu, Keith Bostic, George Coulouris etc. Plus all the other
individuals who have shown support.

All,
I've just received a couple of _huge_ tarballs from Keith Bostic
with the following PDP-11 UNIX stuff:
1BSD
2.10BSD
2.79BSD
2.8BSD
2.9BSD
2BSD First 2BSD tape.
3BSD First 3BSD tape.
pascal.2.0 Pascal distribution
pascal.2.10 Pascal distribution
32V
Documentors WorkBench.
pdp.archive ???
pwb 3 slightly different & incomplete versions
v6 6th Edition
v6.compat ???
v7 7th Edition
v7add The "40 changes" tape.
v7m Follow-on release to V7
Due to space considerations (& a lack of time), I haven't been able to
extract anything into the licensed UNIX archive that I run on henry. I'd
also like to try and remove duplicates where possible.
If you're interested in a particular thing from the tarballs, please email
me and I'll extract the relevant sections.
Also: 300+ signatures on the PDP-11 UNIX src license petition. I just sent
a reminder email to SCO to see what they're doing with it.

Dear PDP-11 & old Unix enthusiasts,
Status report of our petition to SCO about UNIX src licenses. I received this
from Dion Johnson last week:
Warren,
Thanks for your latest news. That's great about the signatures.
Yes, I perused the earlier list and it's really amazing that
we have such famous support for this. I am sure it will be
a great PR victory when we finally get this arranged.
Our exec VP (Doug Michels) is on your side. I am annoying our
legal folks, bless their hearts. :-) They have a job to do also and
I want to be sure we are protecting SCO's interests in the code
in the right ways.
I expect an answer in a week or so. I suspect there will be
further internal iterations here as we craft a license that works
for all parties.
So the right answer to publish is:
"SCO is pleased to entertain this request from so many loyal and
famous fans of UNIX. We are looking into how we can provide this
source code. No promises at this time, since there are some
intellectual property issues that must be resolved, but we will
do what we can."
I'll email when I hear more. It occurred to me that if SCO agree to src
licenses and people buy them, then they will of course want the software.
I already make the stuff available to several people, on the trust that they
have existing src licenses (e.g show me the first 100 lines of v7 nami.c etc.)
At the moment, it's all sitting as .tar.gz files on my desktop box.
If I become the `central repository' for the software, then I'd like to
set up access procedures which ensure that only legitimate users can access
the archive, and that eavesdropping or hacking access to the archive
shouldn't divulge its contents easily.
I'm after comments from you guys, the end users of the archive, as to what
sounds good, ok, bad, annoying and/or plain stupid to you.
Proposal
--------
Make the archive available via FTP:
- To prevent capture of ftp passwords, I suggest that each license
owner has an ftp account, and authentication is done using S/Key.
To distribute the S/Key key phrase or a number of S/Key pass
phrases to the license owners, I suggest using PGP email.
Keep the archive files encrypted:
- This will stop hackers who penetrate the archive from getting the
plaintext version of the files. I suggest using PGP with a very
large key size to encrypt the files. The key won't be kept on the
archive machine.
Transmission to license owner - Suggestion A:
- Transmit the PGP encrypted files `as is' to the license owner
via ftp. Shortcoming: every license owner has the same private
key required to decrypt the files. A hacker only needs to find
one vulnerable license owner to get the key.
Transmission to license owner - Suggestion B:
- On-the-fly PGP encrypt the files using a key specific to the
license owner. Shortcoming: end user must have a personal key
plus the common key, and must decrypt everything twice.
Transmission to license owner - Suggestion C:
- On-the-fly decrypt the archive file, and on-the-fly re-encrypt
it using a key specific to the license owner. End user only needs
one personal PGP key to decrypt the file. Shortcoming: the key
required to decrypt the file back to plaintext must exist on the
archive server. Hackers who break-in can thus get plaintext.
I think I prefer Suggestion A. For all 3 suggestions above, PGP
private keys will be sent to license holders using PGP email.
Anyway, this is an off the cuff set of ideas. I certainly want to keep
my butt from being sued off by SCO :-), and so I need to authenticate users,
keep audit trails of downloads and logins, and take reasonable steps to
prevent non-legitimate users from accessing the licensed material.
I'd really like feedback from you about the proposed scheme for providing
access to this old UNIX software!
Thanks in advance,

I'd still have to encrypt the archive files that are resident on disk.
Also, ssh is more of a `general' login account. scp would allow someone
to retrieve /etc/password :-)
If I could restrict scp access, that'd be an ok alternative.

Yes, I'd thought about cutting a CD directly from the current archive,
and certainly having someone (SCO, me?) distribute files on CD would
make the administration a lot easier. I guess license holders could
buy `upgrade CDs' if the archive changes.
If SCO come to the src license party, I certainly will ask them about
pressing CDs and distributing them as part of the license sale.
Thanks for the input Steven!

Isn't ftp for a $200-programm secure enough? I'm doing beta testing
for a programm, which costs $1100 and they distribute the passwords
for ftp by unencrypted mail. They do that allready for a few releases
and I don't think they had any problems with that.

I don't think you need a very large key. Everyone, which has the
choice to crack a 512bit key or to pay $200, would choose to pay.

I think pgp is to difficult to use for some. You could use a simple
encryption programm like: ftp://isidor.ethz.ch/pub/simpl/safer.V1.1.tar.Z
which should be very portable. The passphrase could be distributed on
the license.

No, I'm afraid not.
I have been told that there is a 9-track tape drive at another centre in
London, but I haven't pursued it 'cos I was waiting for contact from your

We have a TU81+ 9 track tape connected to a VMS Alpha here. So, if you send
me the tape, I will try to read it. Worked perfectly some months ago for a
10 yr. old tape from a DECsystem 10 ...
