Hello Vinod.

It shouldn't be the case one expects.

Try setting the simple root password or make it null (not recommended).

You can have another user created temporarily and provide it root priviledges.
Reboot the machine into multiuser mode and Check.

Let me know what your investigation says..

Good Luck!!

Hi Vinod,

Are you running in trusted mode? Is shadow passwd installed?

How did you reset the password in single-user mode?

While booting I typed hpux -is and its booted in single user mode and i changed the passwd by passwd command. I restarted after that new password didnt worked ....

Hi again,

Run
# /usr/lbin/modprpw
This will report if is trusted or not trusted.

Run
# ll /etc/shadow
to check if you shadow passwords

---
I restarted after that new password didnt worked ....

Just wondering, did you use a @ or a # character in you new password for root?

Robert-Jan

After you changed the password in single user mode, when you rebooted, did you try to login over a network connection or did you still use the console login as you di8d with single user mode? This system may have restricted root login which is controlled by the presence of the file: /etc/securetty. If it exists, root is not allowed to login except through the ports defined in this file (typically: console).

Hi

1) boot in single user mode, untrust the system,change the root password, reboot, logon as root and then make the system trusted again.

Shalom,

You could also try nulling out the root passwd in the /etc/passwd file.

Then you can boot the system to multi user mode, do a quick su - root which is normally permitted even in very secure systems and set the root password in multi user mode.

Hello Vinod:

Another thing that you could try is restoring the /etc/passwd from /usr/newconfig/etc/passwd.

This is only if the system is not trusted. Before doing it, make a backup of you current /etc/passswd in single user mode(this is very important) and then:

# cp /usr/newconfig/etc/passwd /etc/passwd
# passwd

Enter new password.

# init 3

If you are able to login with the root password, then restore your backed up /etc/passwd file to itÂ´s original location.

Change the password again.
# passwd

Just in case, after that reboot the system and make sure everything is working normally.

Any special characters in your password like "#"?

Try with a "simple" password.

Hello Vinod,

Keep the customize .profile and /etc/profile away from sometime and copy the standard profiles from /usr/newconfig/etc.

set /etc/hosts.equiv on the host to have access from other box while in Single User mode.

I know, As suggested you'd have set the simple/null password.

Check for man hosts.equiv for referrence.

System re-install would have been the last option but I know Admins here are smarter than Mischievous kid on your system. :-)

Good Luck!!

Remove /etc/securetty file and try with the changed password.It should work.

Oops. This file should not exist if you aren't going to limit root login locations. If it is 0 bytes, then root can NEVER login. That's what this file does. If it has "console" then root can login on the console. If it haas nothing, then root can never login from anywhere.
