Unable to Load Fog PXE Menu

[lordbob75]

I can’t get my PC to actually PXE boot and load the first Fog menu. All I’m trying to do at this point is the initial host registration.

I’m very new to Fog and I’ve never much with Imaging software before, so I’m trying to learn about it.

Currently I’m getting a “Could not boot: exec format error 2e008081” message everytime I try to PXE boot.

I’m using an Asus Z270-a motherboard with Secure Boot disabled, and UEFI.
I’ve spent a few hours searching the internet for the issue and basically everything was saying it was secure boot causing the issue.

Any assistance would be appreciated.

What do you have configured for dhcp option 67?

That error almost sounds like an iPXE error and not a uefi boot loader error. If you could take a picture of the error with a mobile phone and post it here we can see the context of the error.

Also what version of fog are you using?

Finally, if you could call this url, replacing the <fog_ip_address> with the real IP address of your fog server we can see the text behind the iPXE menu. http://<fog_server_ip>/fog/service/ipxe/boot.php paste the results in this thread.

@george1421 not sure if I replied in the right way to this thread since it’s above your post.

PFSense does not appear to have an Option 67.

Picture of error:

I am currently running FOG version: 1.5.5
I’m using a docker container (https://hub.docker.com/r/mudislander/fogproject//Dockerfile/), which I realize is not the newest version. I’m fairly sure I have to wait for the update to the container rather than trying to update it myself, but not positive on that.

@lordbob75 There seem to be at least two different IP addresses involved (as seen in the picture). What systems do those belong to? If you ever changed the IP of your server you want to check our wiki on how to do this properly!

The other thing I am wondering is when you get to the Exec format error? Does the FOG menu load and when you try to register a host it fails with the error or do you never get to see the menu?

While 1.5.5 is old I don’t see this version would cause this problem per se. I would still suggest you setup your own server after you have played with the Docker version a bit.

The forum is setup to have the newest posts at the top.

@Sebastian-Roth

Correct on the 2 IPs. *.3 is my actual Server IP and *.200 is the IP of the container. This is how I originally set it up if that matters.
I could try removing the separate IP, but I’d have to mess with the ports and stuff, and I didn’t think it was necessary.
Here is a screenshot of the container settings that may be helpful.

I get the error right when I first PXE boot. Once I choose IPv4 PXE boot, the picture above is the only thing I get. Takes about 1 minute from initializing devices to failing.
I have never seen the FOG menu yet.

I could definitely spin up a VM and try running FOG on that, but my end goal would still be to use a containerized version if possible.

I have to say that I have not used docker much yet. So I am not sure what you mean by “actual Server IP”. Can you run ip a s within the container and post output here?

We don’t seem to find the time to support an official Docker image. So it’s up to community (you and other people) to keep this up to date.

@lordbob75 The “Exec format error” makes me think the client might be the issue. Do you have other machines at hand to test PXE booting to see if another one can properly load the FOG menu?

On the other hand I can imagine the iPXE binaries in 1.5.5 causing the problem. It’s not very likely but you never know. You can download the latest binaries from github and give it a try.

It’s the IP address of my server. The container was set with it’s own IP instead of using the servers IP address like other containers since it wants to use port 80 (which the webGUI for the server runs on).

ip a s output:

Fair enough.

I just pulled out a 10ish year old laptop (still works!) with a BIOS (not U/EFI) and PXE booted it. No errors, but it just sits and hangs after the:

http://192.168.1.3/fog/service/ipxe/boot.php... ok

Oh, and I’ll try updating the binaries later, out of time for the day.

[lordbob75]

OK, so I fixed it.

Honestly not really sure how, but here’s what I did:
Removed the container and data
Reinstalled with the server IP in the config set to .200 as well

That’s all it took. Tried this as part of setting up a virtual machine to run it, but ended up not needing to finish that setup.

Thanks!

@lordbob75 Good to hear you got this fixed! Though the error message for me didn’t point to be the IPs to be the issue. But well.

Would you be interested to get in touch with the person who created the Docker image to see if he/she’d be keen to update the FOG version?
