Netboot across subnets (Intel)

[vampyreapocalyps]

Hi everyone

I want to get a netrestore server going at a very large client, however the netrestore server is on a different subnet than the clients. I read Bombich’s article on netbooting across subnet but it is tailored for OF, not the new EFI for intels. Has anyone had any experience with this yet? How did you configure the clients to netboot across a subnet?

You are supposed to be able to use the bless command in current versions of OS X. However here is the script we use to set it via nvram.

#!/bin/sh

setName="bork.nbi"
imageName="bork.dmg"
server="10.10.10.25"

/usr/sbin/nvram boot-args="rp=nfs:${server}:/private/tftpboot/NetBoot/NetBootSP0:${setName}/${imageName}"
/usr/sbin/nvram efi-boot-device="<array><dict><key>IOMatch</key><dict><key>IOProviderClass</key><string>IONetworkInterface</string><key>BSD Name</key><string>en0</string></dict></dict><dict><key>IOEFIDevicePathType</key><string>MessagingIPv4</string><key>RemoteIpAddress</key><string>${server}</string></dict><dict><key>IOEFIDevicePathType</key><string>MediaFilePath</string><key>Path</key><string>NetBoot\NetBootSP0\\${setName}\i386\booter</string></dict></array>"
/usr/sbin/nvram efi-boot-file="<array><dict><key>IOMatch</key><dict><key>IOProviderClass</key><string>IONetworkInterface</string><key>BSD Name</key><string>en0</string></dict></dict><dict><key>IOEFIDevicePathType</key><string>MessagingIPv4</string><key>RemoteIpAddress</key><string>${server}</string></dict><dict><key>IOEFIDevicePathType</key><string>MediaFilePath</string><key>Path</key><string>NetBoot\NetBootSP0\\${setName}\i386\mach.macosx</string></dict></array>"

It’s a little more verbose than the ppc OF version. Gotta love XML 🙂
