reset root password

[Rosli Ahmad]

Hi,
I need a procedure in reseting root password for DigitalUnix. No one remembers the password. I have never rebooted any DEC server before and wonder how do I get to PROM monitor. I believe we have to issue:
>>>boot -fl s - to get into single user mode and issue :
#/sbin/bcheckrc - to check & mount f/system
#passwd - to reset the root passwd

How do I get to PROM monitor, or the >>> ?

Pls. advise.

Thank you.

On older systems, you might want to try hitting Ctrl-P to get on the boot prompt.

If the machine is still running, use the shutdown -h now command (or "halt" after stopping your applications).
You can also press the "halt" button on the machine.

The SRM console (>>>) is the standard for Tru64 machines, so all actions leads to this prompt.

Hello everyone

If I remeber my experience this case,
I could summary 8 steps.

1.Power on

2. >>> boot -fl s

3. #bcheckrc ; This is action to use vi editor

4. #mount -u /

5. vi /etc/passwd

or #mount -a
#passwd


6.#sync

7.#reboot

But if you want to modity as following files,
/etc/passwd, passw.pgg, passwd.dir,
you're supposed to uss vipw

Have a nice day

maybe the /etc/passwd.dir and .pag file will prevent the passwd command. So you must add the delete step of this files between

vi /etc/passwd and
passwd

Hope it helps,
