How do I change the admin password when it is lost or unknown?

IPSO (Operating system),   System Configuration
for version: 3.0 And Later


date modified: 01/29/2002
This resolution describes how to reset the admin password, should it be
unknown or forgotten. There are some important notes that need to be
considered first:



The supported method is to boot the system into single-user mode and run
/etc/overpw

If you are running IPSO 3.1.3 or earlier on a boot manager platform, (which
could only be an IP650 or IP330), overpw fails. Please ask for Internal
Resolution 1961 - How to remove config and password if overpw fails. (Newer
boot manager platforms require later versions of IPSO, for which overpw has
been updated.)

If you are running IPSO 3.4.x, then you will be able to login as admin to
the console without a password, but you will not be able to log into Network
Voyager. Therefore,

The use of overpw requires the use of the dbpasswd in order to set the
Network Voyager password to be the same as the login password.


SOLUTION
You must have local serial console access to the unit to perform this
procedure. Keyboard and monitor directly connected to the machine will not
display the "boot:" line, which means you will not be able to perform this
procedure.

Boot system into single user mode. To do this reboot or power cycle the
machine, When you see the line " boot: " you must enter "-s" before it goes
into multiuser mode. (you have about 10 seconds)

* on a ip330 or ip650 you need to type boot -s at the BOOTMGR prompt*


After it boots, it will ask you "Enter pathname of shell or RETURN for sh:",
press Enter key.


Type "/etc/overpw" in the # prompt. It will ask if you want continue, type
"y".

In IPSO 3.1.3 systems and earlier, it will ask you to put a floppy disk into
the floppy drive to make sure you have physical access to the box. Put a
floppy disk into the floppy drive and press Enter key. IPSO 3.1.4 and later
does not ask this question.


The admin password defaults to no password for admin. Continue to boot to
multiuser mode.


Login as admin. Note that you are not asked for a password


Use the dbpasswd command to set a new password:

nokia[admin]# dbpasswd admin newpassword ""

(Note that the "" is necessary to specify (NULL) as the old password.)

Then, save this new password to the configuration file so that you can log
into Network Voyager:

nokia[admin]# dbset :save

if you are defaulting ipso 3.4 or above, blank passwords are not accepted in
Network Voyager. Please see Resolution 6726 to read more about this.
