Chapter 3 Setting Up NetBoot Service 49

Setting an Image for Diskless Booting

You can use Server Admin to make an image available for booting client computers

that have no local disk drives. Setting an image for diskless booting instructs the

NetBoot server to allocate space for the client’s shadow files.

To make an image available for diskless booting:

1 Open Server Admin and select NetBoot in the Computers & Services list.

2 Click Settings, then click Images.

3 Click the box in the Diskless column next to the image in the list.

4 Click Save.

Important: If you have diskless clients, set their boot image as the default image.

For help specifying where the client’s shadow files are stored, see “Choosing Where

Shadow Files Are Stored” on page 46.

From the Command Line

You can also set an image to boot diskless using the serveradmin command in

Terminal. For more information, see the system image chapter of the command-line

administration guide.

Restricting NetBoot Clients by Filtering Addresses

The filtering feature of NetBoot service lets you restrict access to the service based on

the client’s Ethernet hardware (MAC) address. A client’s address is added to the filter list

automatically the first time it starts up from an image on the server, and is allowed

access by default, so it is usually not necessary to enter hardware addresses manually.

To restrict client access to NetBoot service:

1 Open Server Admin and select NetBoot in the Computers & Services list.

2 Click Settings, then click Filters.

3 Select either “Allow only clients listed below” or “Deny only clients listed below.”

4 Select “Enable NetBoot filtering.”

5 Use the Add (+) and Delete (-) buttons to set up the list of client addresses.

To look up a MAC address, type the client’s DNS name or IP address in the Host Name

field and click the Search button.

To find the hardware address for a computer using Mac OS X, look on the TCP/IP pane

of the computer’s Network preference or run Apple System Profiler.

Note: You can also restrict access to a NetBoot image by double-clicking the name of

the image in the Images pane of the NetBoot pane of Server Admin and providing the

required information.
