[IT Tips] - Reset or recover forgotten Admin Password for Exinda
I
have misplaced/forgotten my password to gain access to the Exinda
device. Is there a way to recover a lost or forgotten password?
If the administrator of a system running firmware v5++ forgets the password of the user 'admin', the following method can be used to reset the password to the default password.
Default admin credentials are:
username: admin
password: exinda
The basic procedure is to boot the system to single user and
execute a script to reset the 'admin' password in the active database.
If any database corruption is suspected, the script resets the system
database to an initialized default one. The 'admin' password is not set
in such a database. A system booted to single user mode does not require
a privileged user password.
First, the system must be rebooted or power cycled. It is assumed
the person following this procedure is able to access the system's
console and can see the entire boot process (this is either over a
serial console or the system's direct console).
Step1: Press
the down key when it says "Boot loading stage 2"and select the image to
boot into. Once the image is selected (in this case 0) then press “e”
to enter the edit command mode. This will give the user the ability to
change the commands options that are part of the boot process.
Boot Menu
---------------------------------------
0: exinda-5.4.0.13350 (i386) 2010/03/31
1: exinda-5.4.0.13350 (i386) 2010/03/31
2: memtest86+ v1.70
---------------------------------------
Use the up and down keys to select which entry is highlighted.
Press enter to boot the selected image. 'e' to edit the
commands before booting. 'a' to modify the kernel arguments
before booting or 'c' for a command-line.
Highlighted entry is 0:
Step2: Now use the arrow key and select 1 (for kernel.......) and type “e” again
Boot Menu
---------------------------------------
0: root (hd0,1)
1: kernel /vmlinuz ro root=/dev/sda5 img_id=1 quiet loglevel=4 panic=10 console=tty0
console=ttyS0.9600n8
---------------------------------------
Use the up and down keys to select which entry is highlighted.
Press 'b' to boot, 'e' to edit the selected command in the
boot sequence, 'c' for a command-line. 'o' to open a new line
after ('0' for before) the selected line. 'd' to remove the
selected line or escape to go back to the main menu.
Highlighted entry is 1:
Step3: On
the next screen after entering 'e' go to the end of the line and the
text 'single' should be appended to the end of this line.
Note: The '<' indicates that a portion of the command line is
not seen. The arrow keys allow the user to navigate the command line to
the very end so that above step 2 can be done as below:
Step4: On the next screen select option 1 (kernel.....) and type "b" to resume booting the selected image.

---------------------------------------
Use the up and down keys to select which entry is highlighted.
Press 'b' to boot, 'e' to edit the selected command in the
boot sequence, 'c' for a command-line. 'o' to open a new line
after ('0' for before) the selected line. 'd' to remove the
selected line or escape to go back to the main menu.
Highlighted entry is 1:
Step5: After more boot messages a 'root' user prompt should be displayed as below:
resh-3.2#
Type here: “/sbin/resetpw.sh” as below:
resh-3.2#/sbin/resetpw.sh
Step6: If
successful, the 'admin' password will now be reset to the default
password. The system can now be restarted by issuing the command
'reboot' at the command prompt:
sh-3.2# reboot
