The machine was 'rescued' from the scrap metal place. I can log in to DST with 22222222, but can't access the option necessary to change the QSECOFR password. I think this machine has V4R3 on it.

I think I am going to have to write some tools to hack around with an image file from the load source disk. I have a hex editor I wrote that will display the EBCDIC characters. What I am thinking of doing is grabbing two images of the disk - one as-is, and a second one after I change the password for the DST user 22222222. Then maybe I can find where the passwords are stored.

I'm guessing that the QSECOFR password wasn't included either when he
bought the machine. A company that I worked for years ago had the
same problem:
No
QSECOFR password. But we booted the system into DST and used either
the
22222222 or 11111111 profile to change the password for QSECOFR. That
was, if I remember correctly, a V3 something machine.

Your chances of finding the DST password are about the same as that of
a snowball inside a blast furnace, not gonna happen.

Use Larry's suggestion and from the console, signed on as QSECOFR,
issue the CHGDSTPWD *DEFAULT command.

From there, take the serial number and just take each disk.
To aid in your hacking, stop all parity protection (one less
abstraction
layer).
And good luck i doubt the users/pass are stored in plaintext.
You could also dump an op21 and look at the lic code part...

Keep us posted, i'm curious about this.

best regards,

Well I can tell you it's the top cage, left disk unit, ALMOST

It's possible that it's the 2nd disk from the left.

Now on this quest to find the DST Password with a disk
editor...... Yeah good luck with that.

I believe they are encrypted, and worse in EBCDIC so noodling
for recognizable stuff will be hard.

Why don't you run CHGDSTPWD and reset the QSECOFR DST profile
that
way?

I have this old 9406-720. It has five drives in the cage on
the top left side (below the control panel), and two in the
cage below it. How do I find out which is the load source? I
can only
access DST with the '22222222'
user ID. I need to find the load source device so I can poke
into it with a disk editor and hopefully find where the DST
passwords are stored.

Thanks,
