I currently have an Xserve running 10.6.8, which I have been using as a NetBoot server that I use for my clients to boot to for imaging with Casper. A few weeks ago, my clients simply won't connect to the server anymore. On the client end, I will see a flashing globe, and then the Apple logo with spinning globe underneath for a few minutes, then the client will simply reboot to the local disk. Going into verbose mode, this is what the client says:


efiboot loaded from device: Acpi (PNP0A03,0)/Pci (1C|0)/Pci (0|0) /Mac (<MAC address>)


boot file path:

Loading kernel cache path `x86_64\kernelcache`...


And that's it.


My server's logs show that it contacts the clients with no problems (that I can tell)...


bootpd[92975]: BSDP INFORM [en0] <MAC addr.> NetBoot168 arch=i386 sysid=MacBookPro6,2

bootpd[92975]: NetBoot: [MAC addr.] BSDP ACK[LIST] sent <IP addr.> pktsize 319

bootpd[92975]: BSDP INFORM [en0] <MAC addr.>NetBoot168 arch=i386, sysid=MacBookPro6,2

bootpd[92975]: replyfile /private/tftpboot/NetBoot/NetBootSP0/Casper NetBoot 10.8.x.nbi/i386/booter

bootpd[92975]: NetBoot: [MAC addr.] BDSP ACK[SELECT] sent <IP addr.> pktsize 447

bootpd[92975]: service time 0.276448 seconds


I even created a brand new NetBoot image from a clean install using Apple SIU, and it still does the same thing. The odd part: I have a NetInstall of 10.8.2 housed on the server that clients will boot from with no problems (though it takes longer than it used to in the past; several minutes).


Any ideas where the problem might lie, or what the problem might be?

    Something on your network has changed. The two most likely candidates are:

    1) Network configuration. New switch, router, or policy that is now blocking ports.

    2) Someone has (possibly unknowingly) enabled a DHCP server on the network and it's capturing your NebBoot packets.

    Did you ever get this to work?  I'm having the same issue

    I posted this before and is well worth looking at especially if you have made custom ethernet settings or done any trunking on your netboot server. Must be the MTU frame rate that dictates the functioning of the Netbbot service.

    This might work for some:

         I had the same problem of the netboot image not mounting/opening, spinning globe then booting back to the Mac HD on the client and it was only when I remembered that we had manually experimented with jumbo frame rates and the MTU settings for our 32TB RAID in the Hardware settings for Ethernet ports on our servers. I turned the settings back to configure "Automatically" and 1000baseT on, then the whole NetInstall and Neboot was working perfectly again.
