Password Recovery Procedure

for the Cisco Secure IDS (formerly NetRanger®) Sensor

Description

This document describes how to recover a password on a Cisco Secure IDS Sensor workstation.

Required Files

• The Solaris 2.6 Device Configuration Assistant disk (boot disk).
  You can download the files from the Sun support web site.
• The Solaris 2.6 for Intel (x86) CD-ROM
• Console access to the workstation.

Step-by-Step Procedure

1. Insert the boot disk.
2. Insert the CD in the CD-ROM drive.
3. Turn off the workstation, wait ten seconds, and turn it on.

   The system boots from the boot disk, and after some configuration, the initial Configuration Assistant screen is displayed.

4. Press F3 to do a partial scan of the system for boot devices.

   When the scan is finished, a list of devices is displayed.

5. Make sure the CD-ROM device appears in the list of devices, and then press F2 to continue.

   A screen displays a list of boot devices.

6. Select the CD-ROM drive, and then press the space bar.

   You should see an "X" next to the CD-ROM device.

7. Press F2 to continue.

   The workstation is now booting from the CD-ROM.

8. On the screen for selecting a type of install, choose Option 2, Jumpstart.

   The system continues booting.

9. At the prompt to select a language, choose Option 0 for English.
10. At the next screen for languages, choose Option 0 again for English ANSI.

    The system continues to boot and the Solaris Installation screen appears.

11. Press and hold the Control key and type C to stop the installation script and allow you access to the prompt.
12. Type mount -F ufs /dev/dsk/c0t0d0s0 /mnt.

    The "/" partition is now mounted at the "/mnt" mount point. From here you can edit the "/etc/shadow" file and remove the root password.

13. Type cd /mnt/etc.
14. Set the shell environment so you can read data correctly.
    1. Type TERM=ansi.
    2. Typeexport TERM.
15. Typevi shadow.

    You are now in the shadow file and can remove the password. The entry should be

    root:gNyqp8ohdfxPI:10598::::::

    where the ":" is a field separator and the encrypted password is the second field.

16. Delete the second field. For example:

    root:gNyqp8ohdfxPI:10598::::::

    
    would be changed to

    root::10598::::::.

    This removes the password for the root user.

17. Type:wq!to write and quit the file.
18. Remove the disk and CD-ROM from the drives.
19. Type init 6 to reboot the system.
20. Type root at thelogin:prompt and then press Enter.
21. Press Enter at thepasswordprompt.

You are now logged in to the Cisco Secure IDS Sensor.
