@WielandPP1 Can you confirm if this is now working for you?

@piaFOG26 Are you able to confirm if things are now working for you?

@Paladin1 Thanks, that explains the registration error. Registration reads the machine’s disk, so it needs a disk attached. With no disk it stops with that message every time. That is expected, so you do not need the debug task.

For your question: neither. Do not reinstall anything yet.

The BIOS boot mode on this machine applies to both the network boot and the installed OS. Your image is a UEFI install, so this machine has to network boot in UEFI too. We can try a different iPXE file for UEFI that loads its own network driver. That can avoid the firmware error.

On the FOG server:

Edit /etc/kea/kea-dhcp4.conf. In the classes FOG-UEFI-64-1, FOG-UEFI-64-2, FOG-UEFI-64-3 and FOG-Surface-Pro-4, change "boot-file-name": "snponly.efi" to "boot-file-name": "ipxe.efi". Run sudo systemctl restart kea-dhcp4-server. Set the target BIOS back to UEFI and network boot it.

Tell us if you get the FOG menu or the same ASSERT. If it fails, change the file back. A re-run of the installer also puts snponly.efi back.

@fierke A correction to my last post. The fix is now merged into working-1.6 and rc-1.6.0. Update your checkout and re-run the installer. The installer now writes default.ipxe without those two lines, so you do not need to comment them out again.

You are right that this can happen on other machines too. Any UEFI firmware that never ends its variable list hangs the same way. The update fixes it for all of them.

I would still like the show efi/SecureBoot result and your BIOS version when you have time. That confirms the cause before the iPXE side ships.

@Tom-Elliott I wondered if that was the case, thank you.

@Coolguy3289 I believe we fixed the problem, please confirm and I can solve this thread, thank you!

@mp12 Thanks for the logs. This is a bug in 1.5.10.2482, not your node passwords.

A security change in 2482 removes the storage node password from the node data that the API returns. The image and snapin replicators read their node list from that same data. So they now send an empty password, and every node rejects the login. The Undefined property: stdClass::$pass warning is that missing field.

The fix is merged to dev-branch: https://github.com/FOGProject/fogproject/pull/1770

To get it now, update from dev-branch:

cd /path/to/fogproject git checkout dev-branch git pull cd bin sudo ./installfog.sh -y

Or wait for the next stable release. Your stored passwords are correct, so you do not need to change anything on the nodes.

@AUTH-IT-Center I do believe snponly would be the recommended, rather than iPXE’s driver.

The developers at iPXE wrote the driver on their own (of course using documentation and stuff, but for all intents/purposes it is still a handrolled driver) so anything is possible.

We shipped the native iPXE 2.0.0 mainly because of the feature it allows with actual Secureboot capabilities and instead of embedding everyfile with a custom script, a more dynamic approach for when iPXE releases new version we can upgrade more easily.

For what it’s worth, I would almost want more people to default to snponly.efi (or secureboot/snponly-shimx64.efi if using/wanting secureboot after enrolling your machines of course) because this is supposed to be using the generic driver for EFI boot protocols on the NIC rather then attempting to discover the NIC using a driver loaded.

Glad you have a workaround. I think the cause is the Windows boot manager certificate change, not the image.

Your golden Optiplex installed Windows with Secure Boot on. Windows servicing then added the “Windows UEFI CA 2023” certificate to that machine’s db, and switched the boot files to a boot manager signed with it. The other Optiplex 3000s only trust the 2011 Microsoft certificates, so they reject that boot manager. bcdboot works because it copies the older 2011-signed boot manager.

Can you confirm with two checks, in admin PowerShell, on the golden machine and on one target?

[Text.Encoding]::ASCII.GetString((Get-SecureBootUEFI db).bytes) -match 'Windows UEFI CA 2023' mountvol S: /s (Get-AuthenticodeSignature S:\EFI\Microsoft\Boot\bootmgfw.efi).SignerCertificate.Issuer

If the golden machine says True and the target says False, that is the cause. A newer Dell BIOS may include the 2023 certificate in its default keys. I am also looking at having FOS add it during the Secure Boot enrollment task.

@gmaurice resetting the host encryption in the gui and then restart the fog service and it should be back up and running. You can also use the api for this, the FogApi powerhsell module (links in my signature) I have this Reset-HostEncryption function https://fogapi.readthedocs.io/en/latest/commands/Reset-HostEncryption/?h=reset+host which will also handle this reset.

Your other other option is to look into post download scripts, there’s some examples in the forums and the docs. If you’re using sysprep and unattend.xml you can inject domain join information into the unattend.xml after imaging and before windows launches for the first time, so the computer is joined to the domain before the fog service or any ui is reachable.

@Balage80 Thanks for confirming the enrollment fix.

UEFI boot: I think the cause is two new lines in default.ipxe. They read Secure Boot state from the firmware. iPXE reads it by stepping through every firmware variable, and some firmware never ends that list, so iPXE hangs there.

Please test this: take the new 979-byte default.ipxe and delete only these two lines. Keep everything else.

param secureboot ${efi/SecureBoot} param setupmode ${efi/SetupMode}

Does UEFI boot with that file? Please also post the make, model, and BIOS version of the machine. Note that re-running installfog.sh writes a new default.ipxe, which replaces a manual edit.

Pending MACs: these are not related to default.ipxe. They come from the legacy FOG Client’s Host Registration module. That module reports every adapter Windows sees, including Wi-Fi, Bluetooth, and virtual Wi-Fi Direct adapters. FOG stores each unknown MAC as pending, up to FOG_QUICKREG_MAX_PENDING_MACS per host (default 4). iPXE cannot see those adapters. You can delete the pending MACs. To stop new ones, add MAC fragments to FOG_QUICKREG_PENDING_MAC_FILTER (comma separated), or turn off Host Registration.

@Tom-Elliott
These are the two machines that were just cloned!

I deployed the Snap-in three times:
the two newly cloned machines and one old machine to see if any certificate issues arise with the old computers. All of them were assigned Image B.

The computer, which has not yet been cloned, did not process the snap-in.

Resetting the encryption settings, deleting the snap-in that wasn’t running, and restarting it didn’t help…

Rebooting of the pc helped

FYI for anyone else running into this issue - I believe the problem was that I didn’t erase the /tftpboot images when I switched from http to https. I’m not really sure why that would matter, but when I did that, then re-ran the server reinstall and selected https, the images got but back in /tftpboot and my hosts didn’t see the mac error anymore.

@Priyankha We need a lot more details.

FOG Version

What bootfile is your boot server trying to send?

Is you server sending the right FOG server for option 66/67?

What OS are you trying to capture?

What does the error show or maybe a screen shot? (UEFI Boot looks different from Legacy boot from Mac from arm, etc…)

What type of machine are you trying to image?

What have you tried?

@JJ-Fullmer @edvandro This should be fixed in dev-branch as well, but I agree with JJ here, please upgrade to working-1.6.

@astrugatch Okay thanks and sorry there was that issue.

Can you pull and try installing again?

Thank you!

@Tom-Elliott

I can’t modify the company’s switches or other hardware since the system is in production. I’m currently rebuilding the FOG server on a VM on my PC and doing everything locally; it’ll be easier to troubleshoot that way. Gemini has wiped out all the previous messages and is giving me nonsense—I can’t seem to recreate the environment up to the capture stage anymore. Could you give me a rundown of everything that needs to be done—downloads, decompressing specific files in binary mode, etc.?

Thanks.

@maxcarpone I would ask you, if you’re daring/willing (it’s considered beta but uses the same pipeline with a lot more modern ui, I need people testing, and Fog_newb can likely attest the new ui look and feel though I think they ran into an issue and needed to get functional right away so the snapshotted back)

Upgrade to working-1.6.

I have a goal (along with @JJ-Fullmer ) to try to get working-1.6 to be master/stable branch by October.

1.6 has been “stagnant” since around 2017 and was in relatively stable grounds back then even.

With AI (as you undoubtly can see I’m using to help drive some things) it’s allowed us to get a lot more coding/refactoring and will hopefully present a much better experience of things on the UI side. Without testing I cannot fix UI bugs though.

AI can do some cool things, but it doesn’t know what “wrong/right” looks like, and JJ and I are only 2 people.

There are others on working-1.6 but more feedback is always good.
