change root password

Efim Kushnir — Mon, 25 Aug 2003 11:23:01 GMT

Dear Sirs,

Our admin is leave and we don't know root password to L1000/HP-UX 11.11

When we try change password trought "set_parms root_passwd" under single use mode we see next message:

# set_parms root_passwd
/sbin/set_parms [730]: grep: not found
set_parms: Cannot find dialog for -- using English.
/sbi_setparms.d/15_root_passwd [56]: grep: not found

Can we change root password for succesful in to system or no ?
If yes please says as ?

BR,
Efim.

Efim,

I would use the passwd command rather than setparms.

By the way, is this a trusted system?

Pete

Is /bin mounted?

If yes, is /bin in your path?

echo $PATH

If not, then:

EXPORT PATH=$PATH:/bin

Hi,

# /sbin/mount -a
# vi /etc/passwd
and remove the enqrupted passwd field.

trusted mode

# /sbin/mount -a
# cd /tcb/files/auth/r/

and then delete the actual encrypted password from the root file, the field your looking for is 'u_pwd'.

Hope it helps,

Robert-Jan.

1. Boot to single user mode (which you seem to know how to do).

2. mount -a
This will mount all of the file systems.

3. Set root passwd with "passwd root", as described above.

4. Reboot server with "shutdown -r".
You want to reboot to bring the server up normally. Single-user mode skips some stuff.

Don't let this happen again. Ensure that you know the root password before the system admin goes on vacation. Have a "backup" system admin lined up.
