NetBotz 750 | Resetting a Lost Root Account Password

Issue:
Process for resetting the root user account password for accessing the NetBotz 750 via console or SSH.

Product Line:
NetBotz version 5
NBRK0750
NBWL0755

Environment:
NetBotz v5.X

Resolution:

Reset a Lost Root Account Password

1) Connect a USB-A to Micro USB-B cable to the Console Port on the NetBotz appliance and a USB port on your computer.

2) Open a serial connection on your terminal emulator using port settings:

• Baud: 115,200
• Data Bits: 8
• Parity: None
• Stop Bits: 1
• Flow Control: None

3) Press Enter, repeatedly if necessary, to display the User Name prompt. If you are unable to display the User Name prompt, verify the following:

• The serial port is not in use by another application.
• The terminal settings are correct as specified in step 2.
• The correct cable is being used as specified in step 1.
• The Silicon Labs CP210x driver is installed on your computer. (You can find the driver on www.silabs.com.)

NOTE:  Step 3 is only to verify serial communications and you are not being asked to log in to root at this point!

4) Disconnect and reconnect power to the appliance. Immediately press any key on your computer. If you do not press a key within five seconds after you connect power to the appliance, the appliance will restart normally.

5) Enter the following three commands to allow root password reset:

env set resetpwd true 
env save
boot

Wait for the system to restart.

6) Log on as the Root user (root). When prompted, reset the Root account password. If you are prompted for an existing password (5.3.0 onwards), the default is "apc".

7) Disconnect and reconnect power to the appliance. Immediately press any key on your computer. If you do not press a key within 5 seconds after you connect power to the appliance, the appliance will restart normally.

8) Enter the following three commands to disable root password reset:

env delete resetpwd
env save
boot

Wait for the system to restart normally (can be up to 15 minutes.)

NOTE: If you do not complete steps 7 and 8, the root password will be reset every time the appliance restarts.
