Once you've created your first NetInstall image, which we did last week, you've got what you need to begin using the NetInstall service. But, in order to start the service up, you'll need to configure some settings.
To test the NetInstall service, in addition to your Mac running Server, you'll need to have another Mac connected to your Ethernet network to connect as a client. Remember, every Mac using this service needs to have an Ethernet connection.
Configuring the NetInstall Service
Before you set the service up, let's take a look at what NetInstall looks like before you configure it.
Open the Server app and click NetInstall in the Advanced section of the app's sidebar and take note of the current settings:
- The service is off.
- The Storage Locations setting should say "No volumes selected."
- The "Enable NetInstall on" setting should say "No interfaces selected."
- The Global Access Filter setting should not be checked.
- The Images setting should say "No images available."
For giggles, try to turn the service on.
You should see an error message telling you that the service can't be started until you enable one network interface.
While the error you got was about network interfaces, you'll configure NetInstall from the top down:
The NetInstall service needs a location to store images and, if you're hosting NetBoot images, cache files for computers that have no hard drives. (Yup, you can NetBoot computers even if they have no internal hard drives.)
To set up storage locations:
- Click the Edit Storage Locations button. You'll see a Volume for every hard drive you have connected to your server.
- Click the menu next to the word None under the Stored Data column and choose Images & Client Data.
- Click OK.
This creates two new folders on the volume you selected:
Make sure these folders have been created:
- Open the Finder.
- Click the Go menu.
- Select Go to Folder.
/Library/NetBoot. Note: If you chose a volume other than your boot volume to store images and client data you'll need to type:
/<name of the volume>/Library/NetBoot.
- Verify that both folders are here. Don't close the Finder window when you're done.
You may recall that in our second episode, we talked about the basic network requirements for using the NetInstall service. By default there are no network interfaces enabled. You may also recall that you cannot use WiFi for the NetInstall service. So if you've been playing around with this on a Mac sans Ethernet, it's time to grab your USB or Thunderbolt adapter and get wired.
- Click Choose Ports under "Enable NetInstall on." Note: The resulting window will show you all network interfaces with a physical network connection. You'll notice that I have three network interfaces available in the Network preference on my Mac, but only two are appear in the Network Interfaces window. That's because the Internal for Class interface is not an actual physical network interface.
- Put a check in the box next to the network interface you want to use.
- Click OK.
