	Two weeks I have received two 735 on loan.  They came from a
surplus computer shop, and they did not know what they had, so I am
working on two of the to see if I can get them to work, and If I can I get
one for free in trade for telling them how to fix the others.  They still
have the hpux loaded, but they have the passwords set.  

	I would like to help with the porting effort, but I have not been
able to find a monitor that worked with the composit sync, and such a high
sync rate, and I thought all was lost, but after reading the last
few posts I was able to get one of them talking over a serial connection.  

	Does anyone know if hp has a development version of hpux like
sun has with solaris?  If not does anyone know of a way to reset the
password from the console.

	My only other idea is to find a diff scsi card that I can put
into my other linux box, and try to mount the root partions, and edit the
password file.  

	Any help would be great.

	Depending upon the OS version and the settings, you
should be able to boot the system to single user mode, and reset
the password.  I'm a bit out of practice, but if you ``boot
isl'', and then enter `/hp-ux -is' (for 9.0x) or `/stand/vmunix
-is' (for 10.20), you should be get a single user prompt,
without having to enter a password (later OS versions may
require the root password to enter single user mode.)

	That probably won't work, as the filesystem used by
HP-UX is just enough different that Linux won't be able to mount
it..  If it's a 10.20 or later system, running LVM, Linux
_realy_ won't know what to do with it..

Since you were running as root at single user, you could have
used the `passwd' command to change roots password.

I don't know what I was thinking.  I was so excited about getting into my
new toy I just wanted to get it working.  It has been along time
since I used ed(like) editors.  I hope to have some time to play with it
after all of the y2krap is over.  I have lots of updated to load on
customers computers, so I don't get to play with mine.

Being in a similar predicament with a 710 workstation I managed
to get to the ISL prompt but to boot into single user mode
I needed to enter 'HPUX -is /hp-ux'. However, after file system
checking I got a repeated message along the lines of:

INIT: SINGLE USER MODE

This just filled up my screen.

Any suggestions as to what I can do to get root ?

	Do you get anything besides the above message??  If not,
I'd suggest that either /bin/sh is missing, or HP-UX doesn't
agree with the hardware about where the console is, and the
shell is always getting an EOF when it tries to read the
console.

missing shell.

No, it just repeatedly produces that message.

It manages to boot into multi-user mode OK.

I inherited the machine from my University as it was surplus
to requirements due to upgrading. Could it be possible that
the sysadmins have deliberately done this to prevent inquisitive
students ?

Yes, 9.01.

I have the upgrade media (P/N B7989AA) but it doesn't seem to
contain anything for a cold install, just patches for 9.x to 10.20
although from previous posts I see some people claim to have done this.

Who did you contact regarding the above link?

	Do you see any output from the system rc scripts during
multi-user boot??

	I suppose it's possible, but I'd venture it unlikely, as
it's a bit more pain than the gain, at least in my opinion..

	You might check to see what interpreter is called out at
the top of /etc/rc.  If it's still /bin/sh, go verify what
/bin/sh points to..

	From a strings on a 9.03 init, it appears that init
might attempt to start /bin/ksh, /bin/csh, /bin/sh, and /bin/su.
You might want to verify the existance of those (/bin/su in
particular).

	The 9.03 init I'm looking at also appears to look for
consoles on /dev/systty, /dev/syscon and /dev/console. You might
verify that they all point to useful locations..

	As I recall, there were no `patches' to go from 9.0x to
10.20 (given the filesystem was radically reorganized, etc.), so
I would expect that the `Upgrade Media' should be bootable..
Although, I don't have a copy, and you do..

	The P/N I'm looking at on the above mentioned page is
B6815AA, and is listed as including HP-UX 10.20 Core, ACE 9906
Core/Install CD, Quality packs, etc..

- Who did you contact regarding the above link?

	Who ever answered the phone when I called the US
fulfillment phone number (1800.386.1117, ext 4).  Karen, I
believe.  I'm sure there is another fulfillment operation in the
UK or Europe that could help you out (although I don't see such
phone numbers listed.)

Yes. It performs a quota check etc, gets to a console login before
X kicks in.

How can I do that? I'm not familiar with all the options/commands
of the hpux command from the ISL prompt.

OK. I'll check these.

	I was suggesting you do that from a multi-user login
(assuming you've got one.. perhaps a rash assumption..)

Mark, you seem  to be in the same situation I was, witha similarly
decommissioned 730 (academic leftover): no root, no account at all! It
booted to a X/OpenVue login screen just fine, however. (Had to take it
down hard with the toc switch, after that.)

Not knowing any of the HP-UX specific tricks, I fell back on a maxim
from computer security: 'There is no computer security without physical
security.'

I yanked the boot HD, dropped it onto the SCSI chain of my linux box,
used grep on the 'raw' block device as so:

grep -ba 'root:[^:]\{13\}:'

to find all occurences of something that looked like a root passwd entry,
with crypt()ed password, and fired up lde (Linux Disk Editor) to change
it to the hash for a password I knew. Worked great!  Strangely enough,
I found 6 copies, with three different passwords.

Once logged in as root, I used the standard utilities to change passwords
again, just in case there was something I missed.

Ross

P.S. 
Later, I aquired the Y2K 9.X->10.20 upgrade kit, with the core 10.20
CD. You just need to call the HP fulfillment desk, and give them the
part number from the web site. I order it on 12/7, they shipped 12/14,
FEDEX, so charge. I even recieved and invoice for part B6815AA, cost 0.00
Unfortunately, it's not bootable on a 730. Oh, the webpage that mentions
all this:

http://www.hp.com/visualize/programs/y2k/y2k_menu/y2k_upgr/oskit.html

It give an 800 number for calling from the U.S. You'll have to trackdown
HP UK number to call, I'm afraid.

Thanks for that, it worked a treat. I didn't have lde installed
on my linux machine so I used dd to copy it to another hd doing
a search & replace on the root password.
