Hi all,

New information. When I load the client into FOS debug mode and run iperf3, the client device can only recieve around 50Mbps but can send at 1GBe.

Thoughts:

Given this only happens in FOS, I dare say one of the drivers are not behaving. The machines I am imaging are Dell Laptops G15 5510. These have Realtek ethernet controllers. I have read these are troublesome, is there any work arounds. I have tried updating the kernels to the latest dev kernels via the FOG Web UI, but this does not seem to help.

I would appreciate any help here.

@Tom-Elliott is there a way to find out where its failing

i have the PCAP file if interested?

HP desktop are a pain in the …

we had similar issues and the current solution we use is to deploy the FOG updates but keep refind to v0.11.0.

@marcolefo not yet, i was running 1.5 on centos 7 and now re installed fog 1.5 on alma 9.5, i will let you know if i get the same issue on new OS

Hi! I found the problem. I was reinstall the Linux and FOG (without https). And all PC-s booting now. Everything looks fine.

any help?

fixed it by installing gcc-aarch64-linux-gnu on ubuntu and running the script again. compilation errors are not logged to the script shown on screen, but to the bin/error_logs/ directory in the extracted archive.
Update now ran without issues.

@marcolefo

Okay nothing to do with FOG 😉

ALTER TABLE mysql.column_stats MODIFY histogram longblob; ALTER TABLE mysql.column_stats MODIFY hist_type enum('SINGLE_PREC_HB','DOUBLE_PREC_HB','JSON_HB');

Sorry for the noise

tbh i am running fog on centos 7 so maybe its time to re install the OS to rocky 9.5 or ubuntu 24

what OS do you recommend?

@Tom-Elliott looks like i have to update my fog to 1.6 instead of 1.5 as i thought i resolved it by updating fog to the latest 1.5 but the error is still there on 1.5, i thought it went at first as when i made my first image it saved as a folder but on my second capture its saving as a file again

@MichaelPower said in FOG & iPXE Anywhere - issues from boot menu:

Just wondering if a working bzImage I can use that boots under Secure Boot?

The issue is exactly that. bzImage is not signed so the uefi firmware will not boot it. That is the root of the issue. You could self sign ipxe and bzImage but then you will need to update the certificates in each computer to include your self signed certificate. Its possible but it is quite a bit of work to get it all setup.

Ok,

I finally figured this out. I know it’s not the best method, but I prefer this than having the wording “plain text” Here’s what I did in case someone needs to do the same.

I read that API tokens do not go well as a securestring. Here are some references:
https://jamesone111.wordpress.com/2020/04/10/transformers-for-powershell-parameters-which-take-secrets/, and https://github.com/Azure/azure-powershell/issues/25533.

So in order to get past this, I needed to create another variable as show below:

$testapi1 = [pscredential]::new(“token”,$yourtoken)

You’re basically adding the pscredential above like you’re going to setup a username, but you put something like “token” or any wording as a placeholder for the username, then put the token in.

Then after you define the header you do something like this: $testheader.add(fog-user-token’,$testapi1.GetNetworkCredential().password)

Again it’s not the best method, but I also read a way when you do read-host -aseecurestring and save your api there as a variable, you can dispose that variable so it doesn’t stay in memory.

$test.disposeof

If someone has any better ideas, please let me know as I’m always on here learning new things and want to share as well. This basically can be closed out.

@lucancurtismahoney First let me start with the yada-yada-yada. Imaging over wifi is not supported by the developers of FOG. Imaging over wifi has its use cases but also is not advised because wifi is a shared resource and your entire wifi network will suffer if you try to image over wifi. You would be better served to get a supported (by the manufacturer) usb ethernet adapter and pxe boot over that.

With that said it might be possible to image over wifi if FOS is configured in an (unsupported) way. It will require a custom FOS Linux kernel and some tweaks to the virtual hard drive to add in the needed bits to configure wifi.

Below is a FOG USB debug image that contains a modified bzImage and init.xz files. Use rufus to burn to a 1GB usb drive. The image is less than 500MB so don’t waste a large usb on this boot image.

Understand this boot image WILL NOT WORK out of the box. We will use this for debugging your network adapter. Many network adapters need specific drivers to work with a linux kernel. We will find out what that firmware is with this debug usb.

Use rufus to write the image file to the usb drive. Edit the grub.cfg file with notepad++ (not windows notepad) its located in the /boot/grub directory. At the top set the IP address of your fog server, and half way down the variable add in your wifi ssid and password. Remove the curly braces. Save the config file and then take it to your target computer. USB boot this image file on the target computer. You may see some error messages about networking, but that is expected. After a few screens you need to clear by pressing the enter key you will be dropped to a linux command prompt. See if you can see the wifi adapter with this command ip a s If you see something like wlXXXXX then the driver is loaded and you are done. If you only see the loop back (lo) adapter then continue. Key in the following command it will look through the startup messages for anything that mentions firmware. grep -i -e firmw /var/log/messages My bet is there will be a message from the intel wireless (iwlwifixxxxx) saying that it needs a specific firmware to load. Take a clear snapshot of the name of the firmware name with a mobile phone and post it here. I will patch the kernel with the required firmware and upload it with additional instructions.

your right they do support PXE boot i found the option right at the bottom in the bios you can choose between PXE HTTP and iSCSI
i didn’t do enough scrolling down last time i looked.
