@Clebboii Thank you for your comments. I’m following up on your responses below.

It looks like MAC Passthrough is only a thing on Latitude, Precision, and XPS laptops. We utilize Latitudes. We do disable Secure Boot when trying to go into PXE boot. We’re going to try to set up a USB with WinPE to disable bitlocker. What confuses me is that the XPS had bitlocker get triggered when secure boot was off but still made it through PXE. It makes me think Bitlocker isn’t the issue here. The Dell USB-C to Ethernet does not support our Dell Inspirons. We tried an Anker USB-C hub with Ethernet and a usb-Ethernet TP-Link adapter on the Inspirons which didn’t give us the option to PXE boot. 66 and 67 weren’t set up when it worked on the ThinkPads or XPS. We set it up on our Firewall not our Router. It also worked after enabling. Going to look into this once our ThinkPad returns from being issued out as a loaner laptop.

I’ve reinstalled FOG, using the in-built DHCP server instead of the router.
Worked perfectly first time, after setting the router as a relay instead.

Thank you very much for all your help! 🙂

Greetings.
Same issues here with a LENOVO 50S, realteck chipset.
I’va speed of 9 Gbit/min on capture and 0.6 Gbits/min on deploy.
Debian Fog Server, version 1.5.10.1660, latest and beta kernel : same issue.
Do a bunch of test with an another hard disk, new kernel, same issue.

I tested with 5.15.68 kernel and my download speed go from 0.6 Gib/min to 4.5 Gbib/min !

Updating FOG has resolved my issues. Thank you.

Nevermind, looks like it was an error in the script itself.

I just want to know if it is possible. Seems like it should be, but I am having difficulty finding any information online regarding how to actually do it.

@Ced58 I use this model. It’s best to get either the official Lenovo usb c ethernet adapter or the proprietary Lenovo adapter for the special ethernet port on these. Also in the bios there’s a Mac pass through option that you want to set to internal or second Mac address. With the latest version of fog and kernel it should see that internal mac even if you share an adapter for imaging multiple of that device.

@rodluz said in Lenovo ThinkPad L14 Gen 5 - kernel panic:

@jflash Great! Did you use the default kernel from FOG after the update, or did you use the kernel from my repo?

I don’t try older kernel, just put new one 🙂

@Itay1787 I just pushed a change to the dev-branch. Please try installing it again from there and let me know how it goes.

@alterak If you know how to program linux bash scripts this is possible. You will need to edit a script called fog.man.reg that is in FOS Linux (the OS that runs on the target computer to capture/deploy images). I have a tutorial on modifying that program to set a default hostname. But the concepts you need to do what you ware are listed here: https://forums.fogproject.org/topic/14278/creating-custom-hostname-default-for-fog-man-reg

I found out what’s causing the problem. The HP BIOS somehow configured the hard disk as a RAID by default. Removing the RAID, and the machine will boot to Windows after iPXE instead of looping.
Thank you for your input.

@Faurel ok good that looks like a clean dhcp process. It would be helpful to have the pcap file in my hand, but you want to expand the OFFER packet. The OFFER packet you can tell from the Info column.

In the packet you may need to expand the dhcp section. You should see the image similar to below. What is important is the next server IP address should point to IP address of your fog server. and boot file name should be ipxe.efi. You see in this example that the boot file name was not given, this is the error with this packet. The next server and boot file are in the ethernet header. This is the legacy bootp pxe section.

The next place you need to check is the dhcp options below. You should see dhcp options 66 which should be the IP address of the fog server and dhcp 67 should be the boot file name of ipxe.efi. In this picture this packet is also in error since the dhcp server is not sending out all of the pxe booting info. So if your offer packet looks like this you have a problem.

@alterak said in FOG operation in different network segments:

is there a possibility of automatic separation of locations,

I’m not sure I fully understand the question, but if you are asking can it automatically pick which location to select based on the IP address of the computer being registered. The quick answer is no, FOG doesn’t currently have that capabilities.

The bit longer answer is it could if you can be a little creative and can do a little linux bash script programming. In a nutshell, you can customize the bash script that is setup for full registration of computers. The basics of what needs to be done is covered in this tutorial: https://forums.fogproject.org/topic/14278/creating-custom-hostname-default-for-fog-man-reg

The IP address bit can come from this script: https://forums.fogproject.org/post/69725 This post is for getting the IP address to be used in a FOG postdownload script. But the concept will be the same for the fog.man.reg script.
