There are several options you can do to reset your root password in the case you lost it.
The following describes two possibilities with different requirements:

1. You need a serial nullmodem cable and a workstation with serial interface and a terminal program
2. You need video and keyboard attached to the firewall.

Each Endian Firewall Appliance will have a serial interface (Console interface) but no Video and Keyboard connectors. If you have your own hardware you probably will have only Video and Keyboard but no Serial Interface.


Solution 1

Connect the serial nullmodem cable to the console port of your Endian Firewall and the other end to your workstations serial port (COM1).
Use a terminal program (Minicom for Unices, PuTTY for Windows) in order to connect to the Firewall. The necessary parameters are:

• 38400 baud
• 8 bit
• No parity bit
• 1 stop bit

After successful connect you should find a menu with 5 possibilities. One of them is "Change Root password".
Select that item and change your password.


Solution 2

1. Connect the video and keyboard and reboot your Endian Firewall.
   
2. During boot you will see a graphical menu on a grey background with title GNU GRUB. Press a cursor button in order to stop the countdown. Otherwise it will boot automatically.
   
   
3. Select the first menu item and press 'a'.
   
   
4. You should see:
   
   grub append> root=/dev/hda3 panic=10 ro
   
   Add 'single' separated with a space in order to finally have this line:
   
   grub append> root=/dev/hda3 panic=10 ro single
   
5. Press ENTER which starts the boot process
   
6. After the boot process the commandline prompt on the bottom of the screen looks like this:
   
   sh-3.00# _
7. type
   mount -o rw,remount /
   
8. type passwd and confirm pressing ENTER
   
   
9. follow the instructions
   
   
10. If you need to change also the admin password, do the following:
    
    htpasswd -m /var/efw/auth/users admin
    
    and follow the instructions.
11. sync
12. reboot
