Changing your endian firewall root password incase you forgot it.

Posted by Isaac Zarb on July 28th, 2009
I forgot my endian fw root password!!! HELP.. What now?
 

You have 2 options to reset your root password in the case you lost or forgot it.

  1. You will need a serial nullmodem cable and a pc / mac with a serial interface and a terminal program
  2. You will need a screen and keyboard attached to the firewall machine.

The Endian Fw Appliance’s 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
(used for Appliance)
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 to connect to the Firewall.
