Recovering Root Password for CAM/CAS
Use the following procedure to recover the root password for a CAM or CAS machine. The following password recovery instructions assume that you are connected to the CAM/CAS via a keyboard and monitor (i.e. console or KVM console, NOT a serial console).
Step 1 Power up the machine.
Step 2 When you see the boot loader screen with the "
Press any key to enter the menu..."
message, press any key.
Step 3 You will be at the GRUB menu with one item in the list "'
Cisco Clean Access (2.6.18-194.el5
)." Press "e" to edit.
Step 4 You will see multiple choices as follows:
kernel /vmlinuz-2.6.18-194.el5 ro root=/dev/cciss/c0d0p2 console=tty0 console=ttyS0,9600n8
Step 5 Scroll to the second entry (line starting with "
kernel...") and press "e" to edit the line.
Step 6 Delete the line "
console=ttyS0,9600n8" and edit the line so it appears as follows:
kernel /vmlinuz-2.6.18-194.el5 ro root=/dev/cciss/c0d0p2 console=tty0 single
Step 7 Press "b" to boot the machine in single user mode. You should be presented with a root shell prompt after boot-up (note that you will not be prompted for password).
Step 8 At the prompt, type "passwd", press Enter and follow the instructions.
Step 9 After the password is changed, enter "reboot" to reboot the appliance.
