It boots to the Fog menu but when you select Full host registration and inventory it gives the error in the screen shot.

That’s impossible. Please take a new picture of the error and port here!

The screen shot you provided happens before the iPXE menu. Unless its the case when you pick full registration from the iPXE menu the system just reboots. Then that screen would appear.
As far as the pcap it will create the pcap in the directory where you ran the tcpdump command.

@george1421 I have the file now. Do I just upload it here? Thank you for your help.
-
@John-L-Clark you can upload it here, just put .txt on the end since I don’t think the forum supports .pcap files.

@george1421 I looked at with Wireshark but had no idea what I was looking for.
-
@John-L-Clark I’m only seeing the tftp transfer. Is the target computer on the same subnet as the fog server? I would expect to see dhcp packets from the target computer or inform packets from other computers on the same subnet.
In this case I want to see the dhcp packets to what the client is announcing itself as as well as what the dhcp server is telling the client to do.
-
@george1421 The client is on a separate subnet than the server. I will run it again and see if anything is different.
-
@John-L-Clark ok to collect those logs we’ll need to install wireshark on a witness computer (i.e. a second computer on the same subnet) and grab a pcap that way.
Use the capture filter of
port 67 or port 68to only grab the bootp stuff. -
Is this what you need? Thanks
-
@John-L-Clark This doesn’t appear to be a wireshark pcap file, but a text file with pcap data. How did you collect this?
-
@george1421 So now it is booting to the fog menu and I select full host registration and it reboots and goes to
-
@george1421 I used wireshard but saved it as a text file. I have the pcap also. I renamed it and added it.capture.pcapng.txt

@John-L-Clark OK I have it lets switch over to chat for quicker turnaround. Look at the chat bubble at the top of the forum panel

@george1421 Thank you for all your help. Updated Kernal helped with the new network adapter.

Ok we have a solution here after debugging and chatting for quite a bit.
This Yoga L13 has a built in network adapter that is connected to ethernet through a port replicator/dongle. It is not a USB/USBC type adapter its just a port replicator.
Debugging showed us that two nics installed.
Network Controller 8086:02F0 Ethernet Controller 8086:0D4FThe 8086:0D4F ethernet adapters comes back to a Intel I219-V. Looking at the kernel driver database that network adapter was first added to the 5.5.x linux kernel. Both 4.19.101 and 5.1.6 kernels that the FOG Project offers are too old for this hardware.
ref: https://cateee.net/lkddb/web-lkddb/E1000E.htmlTo test/solve this problem I built a one-off linux kernel v5.5.3 using the FOG configuration file from a recently create one off kernel I had for Mac T2 workaround. The 5.5.3 kernel built ok and tested ok in the OPs environment. With the 5.5.3 linux kernel the target computer was able to complete a full registration and the OP said he was going to test imaging later.
So for this issue the answer was to create a one off kernel of version 5.5.3 until the FOG Project releases an official kernel that is at linux version 5.5 or later.

@george1421 Great work!!! Do you know if this driver was defaulting to be enabled or disabled in the kernel config. Just wondering where I would note down that information to not loose it till we get to use 5.5.x or newer…
