@george1421 Thank you for your help.
Since we have only few other computer models and static dhcp entries for all computers that might be used with fog, knowing that “testing” the different PXE-Loaders (if the ipxe.kpxe doesn’t work) helps a lot.

I hope I gain enough experience, that I can give this great community a bit back some times.

You guys are fabolus, giving me input faster than I mangage to run around on this floor to test it

Just for clarity here the only thing we are trying to PXE boot is the Samsung TC222W, right?

Right. (Long term more, but ATM only the Samsung TC222W)

@Tom-Elliott said in Trouble setting up FOG 1.3.3 (PXE-boot problems and Kernel panic):

This is sounding more and more like the device is getting information from pxelinux.0. In particular the messages about “Pre-eXecution Boot Environment.”

If I recall properly, this message get’s displayed by the ipxe.krn file which would ONLY happen if pxelinux.0 file is being called (unless somebody else made a change).

Would you mind trying:

mv /tftpboot/pxelinux.0{,_bak}
cp -p /tftpboot/{undionly.kpxe,pxelinux.0}

Tried it, didn’t change anything.

@george1421 said in Trouble setting up FOG 1.3.3 (PXE-boot problems and Kernel panic):

@Doppelgrau ok I see this has a marvel network adapter.

Lets try changing the iPXE boot file from undionly.kpxe to ipxe.kpxe. Maybe the undi code is a bit flaky. Understand what you have is a non-standard system so we may need to test a few iPXE kernels until we find the right one.

Since the dhcpd admin isn’t in the office anymore, tried the “rename hack” (undo the pxelinux.0 try, changed to ipxe)

root@fog:~# cd /tftpboot
root@fog:/tftpboot# mv pxelinux.0_bak pxelinux.0
root@fog:/tftpboot# mv undionly.kpxe undionly.kpxe_bak
root@fog:/tftpboot# cp -a ipxe.kpxe undionly.kpxe

And it worked, could register the TC222W.

Thank you so much for your support.
Tomorrow I can try Immaging with fog.

@george1421 yes, that screenshot has been taken after >10 minutes of no change.

The PXE problem:

@Doppelgrau said in Trouble setting up FOG 1.3.3 (PXE-boot problems and Kernel panic):

group {
next-server <fogIp>;
filename “undionly.kpxe”;
host bauwi-test { hardware ethernet 14:bb:6e:dc:05:d2; fixed-address <clientIp>; }
}

Where is this coming from? I know what it is, but where did you set it up?

That’s from the dhcpd-Server admin, that is used in the subnet. (So I did not set it up).
But the setting seems allright, plugging the device into an other subnet where the dhcpd is not configured to issue opition 66&67 the pxe-menu times out.

@george1421

They set option 66 and option 67 currently. (the dhcpd-Config-extract

@Doppelgrau OK don’t do more than one step at a time.

Promisse, won’t do in the future, just wanted to make a clean reproducable setup.

Since the device is in legacy (bios) mode, you need to configure your dhcp options 66 to the ip address of the fog server and dhcp option 67 to undionly.kpxe
As for the iPXE stuff you need to use the iPXE kernels (undionly.kpxe or ipxe.efi) that come with the fog server and not some third party iPXE kernels.

Using the fog-Kernels.
Server-Setup:

• Debian 8 Basic install
• Install all updates; tsm-backup-client
• Downloaded the fog 1.3.3 tar.gz
• extracted the tar archive
• executed ./installfog.sh in the “bin” folder
• said no to the dhcp-option
• created new user in web frontend
• (updated linux kernel in the fog setting to the latest, but that did’nt change any behavior).

I also did a clean server reinstall, so I’m quite sure it is as “vanilla” as possible.

You mentioned that another group manages your dhcp server. Are they currently setting dhcp options 66 and 67? If not we can install dnsmasq on the FOG server to supply these settings to your local subnet.

Yes, that’s done.

group {
next-server <fogIp>;
filename “undionly.kpxe”;
host bauwi-test { hardware ethernet 14:bb:6e:dc:05:d2; fixed-address <clientIp>; }
}

And booting vith PXE (no help from USB thumbdrive with gpxe) I see some PXE initializiation, that chainloads iPXE and then it stops. (The IMGP_0164 Screenshot)

@george1421 To have a good starting point I just reset the BIOS to the defaults (and default is only legacy boot, legacy PXE), installed a fresh Debian.
Same behavior.

@george1421 said in Trouble setting up FOG 1.3.3 (PXE-boot problems and Kernel panic):

Tell me a bit more about this hardware since it doesn’t appear to be a standard computer.

Is this a uefi or bios (legacy) firmware device?

It’s a display with a small (AMD dualcore with integrated GPU) computer embedded in the display, designed to run as a thin client with Windows (embedded/IoT), or Linux based systems.
The BIOS has an UEFI mode and one “Legacy” mode.

Is this a new fog install or has it been in place for a while? What I’m getting at is, does it work for other hardware just this one is being a pain.

It’s a new install, wanted to try cloning the configured linux-system.
Since I haven’t other Hardware for tests, I used an vmWare VM with a gPXE .iso, didn’t had options 66/67 set (other dhcp server) but with chainloading on the gpxe comandline it worked.

What are you sending precisely for dhcp options 66 {next-server} and option 67 {boot-file}.

group {
# Test
next-server <fogIp>;
filename “undionly.kpxe”;
host bauwi-test { hardware ethernet 14:bb:6e:dc:05:d2; fixed-address <clientIp>; }
}

What system is your dhcp server for this network?

Not sure which dhcpd exactly, since an other department is managing it. Looks a bit like the isc-dhcpd3.

Server

• FOG Version: 1.3.3
• OS: Debian 8
• default install (in a virtual machine) expect external DHCP-Server

Description

1. When using PXE-Boot (or a usb drive with gpxe) loading undionly.kpxe works, it chainloads ipxe, but then there is no progress anymore.
2. If I use usb drive with gpxe to chainload the ipxe.kpxe directly, I get the FOG menu, but when I select an option (e.g. adding to inventory) I get a kernel panic.

Client used for the Test is a Samsung TC222W, running a small Debian Desktop.

Any hints what I’m doing wrong?
