Hi,

Boot the system and interuppt the boot process.

At ISL prompt

ISL> hpux -is ( this will boot your system is single user mode )

Change your password will the passwd command.

This is for the non-trusted system.

Interupt the boot process and boot in single-user mode.

When you see the console prompt, press . BOOT PRI, Interact with ISL? Yes
When you see the prompt, enter hpux -is. That will bring you up in single user mode as root. You can then do passwd and change the root passwd.
Reboot and you are done.

Reboot the system, if you don't have root access you can reset it within GSP mode by doing a CTRL-B and "rs" in GSP prompt. When the system boots up, interrupt it (usually it's say hit any key to stop the bootup). and in ISL mode simply ..
ISL> hpux -is
Once you see the "#" prompt, change your password (root's) and reboot.

Hi Andy

Genrally people create a second user as powerful as root for such emergencies . All you can do is the following :

1. boot in single user mode ie hpux -is at the ISL prompt and change the passwd of root.

2. Incase you have set up as a trusted system , may be do a rlogina nd then change the passwd.

3. lokk at he following :

Reboot to single user mode.

If you have less than perfect security,...

Rlogin from another system with root priviledges, then set the root password field in /etc/passwd to null (no password). Login and set the password up.

If your FTP security is poor,...

ftp on as another user, get the /etc/passwd file (ascii), set the password field to null and then upload again.

Can you perform an "echo bob::0:3::/usr/bin/sh >>/etc/passwd" as another user to create an root-priviledge entry?

Have you set your system to allow root logon to the Console even though the root acct is disabled?

Tried the password crackers at the Porting Centre?

Most of the solutions require you to have some sort of root access to change the password, but what if you don't?

I had one system I could not log into, and being a production system, I could not simply reboot.

My solution was to use Openview Operations (OVO/VPO/ITO or whatever they are calling it these days). I created an OVO application that allowed I/O, running as root, to do a "passwd".
