If you no longer know the root password for your ClearOS system, you can use the following steps to reset it. For security reasons this procedure cannot be carried out remotely; it must be done from the console (keyboard and monitor) while physically at the server. For ClearOS 7.x systems, click here. For ClearOS 5.x systems, click here.

First, you need to boot your system into maintenance (single user) mode:

• At the boot splash screen, press any key to stop the countdown timer.

• Select the ClearOS version with the version of the Linux kernel that you wish to boot. This will usually already be selected or there may be one item listed.

• Type e to modify the boot procedure.

• Select the line that begins with 'kernel' and type e to modify the line.

• Make sure that the cursor is at the end of the line

• and press the Spacebar and then type single. Press Enter to exit edit mode.

• Type b to boot the selected item and begin booting up your system in single mode.

The boot will continue as it usually does with the exception that it will not run any of the traditional items (init3 or init5).

Once the operating system has loaded you will be at a prompt similar to the following:

[root@gateway /}#

• Type the command passwd and press Enter. You will see the following:

[root@gateway /}# passwd

Changing password for user root
New password:

If you have used a weak password (one based on a dictionary word) it may state:

BAD PASSWORD: it is based on a dictionary word

In this mode, it will take weak passwords in spite of the fact that they are weak.

• You will then be asked to re-enter the password to confirm it and will subsequently receive a confirmation that the root password has been reset.

Retype new password:

passwd: all authentication tokens updated successfully.

• Now type in the command reboot and press Enter to restart your ClearOS system.

[root@gateway /}# reboot
