Appendix F: Basic Troubleshooting<br />

Powering up the system to the Administrative kernel<br />

Powering up the<br />

system to the<br />

Administrative<br />

kernel<br />

636<br />

You must be in the Administrative kernel to perform certain system<br />

maintenance tasks such as installing s<strong>of</strong>tware or creating a full system backup.<br />

Follow the steps below to boot the system to the Administrative kernel when<br />

your <strong>Sidewinder</strong> <strong>G2</strong> is powered OFF.<br />

Important: When you are in the Administrative kernel, all network connections are<br />

disabled and Internet services are not available. Type Enforcement is also disabled.<br />

1 Attach a keyboard and monitor directly to your <strong>Sidewinder</strong> <strong>G2</strong>.<br />

If your system has multiple keyboard/monitor connection ports, you must<br />

attach the keyboard and monitor into the same keyboard/monitor connection<br />

port pair (that is, attach both items either to the front connection ports<br />

or the back connection ports).<br />

2 Turn the <strong>Sidewinder</strong> <strong>G2</strong> ON by pressing the power button.<br />

3 When the “Booting <strong>Sidewinder</strong> Operational kernel” message appears,<br />

press any key (excluding Esc) to interrupt the boot sequence.<br />

The number sequence 4, 3, 2, 1, 0 is displayed as the Operational kernel is<br />

booting. Press any key (excluding Esc) before the 0 appears. A Boot:<br />

prompt then appears.<br />

4 Enter the following command:<br />

bsd.sw.admin -w<br />

5 Press Enter when asked whether to check and mount all file systems. The<br />

system prompt will appear. At the system prompt, you can perform any<br />

administrative tasks that require the Administrative kernel.<br />

If you have enabled authentication for the administrative kernel, you will be<br />

prompted to log in before the system prompt appears.<br />

6 When you have finished working in the Administrative kernel, reboot or shut<br />

down the system.<br />

Note: See “Rebooting or shutting down using a command line interface” on<br />

page 42 to reboot or shut down the system from a command line interface.<br />

Enabling and disabling authentication for the<br />

administrative kernel<br />

The following steps explain how to enable and disable authentication for the<br />

administrative kernel. By default, administrative kernel authentication is<br />

disabled. This is because it is generally assumed that the <strong>Sidewinder</strong> <strong>G2</strong> will<br />

be housed in a secure location that is not easily accessible by nonadministrators.<br />

If your <strong>Sidewinder</strong> <strong>G2</strong> is housed in an insecure area (that is,<br />

non-administrators could easily gain access to the physical system), you<br />

should enable administrative kernel authentication.
