@Tom-Elliott Thank you, Tom. The init version is now 2025xxx. I’ll test soon to confirm the SSD info is showing in logs.

@Tom-Elliott I can confirm that it works with v1.5.10.1760. 🎉 Thank you very much! 🙇

@Tom-Elliott

Great news!

I updated my server to Debian Bookworm, restarted the Fog installation, and the accent problem disappeared. Awesome!

Thanks for your help and happy new year 2026, all the best for the FOG project!

@djgalloway Just to add a bit of detail here. All of the work you did was on the iPXE side, which is great work by the way. The kernel driver I updated was after you select an FOG iPXE menu item that is when bzImage is loaded and run. It relies on kernel parameters that is provided by iPXE to find the root file system. This is technically what you fixed by ensuring that default.ipxe/boot.php from the fog server was being called. At the end of the day, I’m glad you got that working because your setup is definitely an edge case that works well in your environment.

@Tom-Elliott said in FOG Client service disconnection, pending snapins are not even being detected:

@Jamaal The client lives on the Machine itself. not on the fog server.

Those logs live on teh Windows machine I forget the exact path but something like:

c:\program files\fog client\fog-error.log or something like that?

Yes, it’s c:\program files (x86)\fog\fog.log

I figured out the issue, lol. I was having a moment, but thanks for helping me out.

@Tom-Elliott Sorry for the lack of clarity in my explanations and the use of screenshots unrelated to my problem.

I have upgrade to the last beta and deploy on registered host works well.
Thank you.

I’ll check if not registered host now appear in Pending Hosts.

Can you help me with bug topic ?
Fog 1.6.0-beta.2141 remove folder with image

@The-Dealman Awesome thank you! and we did publish 1754 specifically due to this issue (manually running the automated processes just in case your org is worried at all 🙂 )

@Tom-Elliott Alrighty. So my FOG server at another location is acting up in the same fashion with the failure to check in.

Before we used it I updated to 1.60-beta.2265 to hopefully negate it but I did not drop the fog table from mysql before doing so.

Are there any logs you want me to pull?

@Tom-Elliott Thanks Tom, yes that looks to have sorted it out thankyou…

@CanadienITGuy Just for your and anyone’s fyi the autoexec.ipxe... Not Found is not an error. It’s more of an info message than a warning or error.
I actually have tested adding an autoexec.ipxe, even just an empty file to remove that message but even an empty file or a file that is even just a symlink or copy/paste of our normal ipxe/boot menu files causes things to break in the process.
The autoexec.ipxe is meant for adding customization to the ipxe process without needing to re-build the ipxe binary. But my testing with it within the fog workflow was that it’s best to just let that message exist and to see it as it being not found means the process will not be altered from your expected Fog ipxe workflow

@thezman007 I would say the pcap file you provided is a model of how a proxy dhcp and dhcp server should interact. The first part of the pcap is perfect.

The second part starting at second #19. The client issues a dhcp discover and the dnsmasq answers right away, the client had to issue a second discover request before the main dhcp server @ 2.2 address responded. This pattern is repeated at the end of the pcap (you can see this if you look at the pcap with wireshark).

So this is only me reading the tea leaves but I think there is something up with your main dhcp server because its being slow to respond to dhcp requests. Understand I only can see 25 second pcap but I find it abnormal. When things go sideways (and it probably will) get a pcap of the failure, that’s going to tell us what’s missing.

I’m going to remove your pcap from your post because its not needed now.

Was not sure which ubuntu version of these (20.04, 22.04, or 24.04) was used as the basis for the FOG release v1.5.10.1734.

Thanks, @FOGBreaker101, for the version you are using.

Some software doesn’t use the latest released version of the OS distro, but often one major version back.

@Infojoe They are one in the same lol and you’re welcome.

Every time after updating to a new build, the first image works, but the next one doesn’t.

@george1421 said in PXE issues:

@Jamaal This problem is solvable but it make take some effort on your part.

Lets start with the basics.

For the DHCP IP zone where your pxe booting clients live, you need to set dhcp options 66 to the IP address of your fog server. And for dhcp options 67 that needs to be snponly.efi or snp.efi. With those settings configured on a MS Windows based dhcp server a pxe booting client should boot. Make sure on your dhcp server that is responding to bootp and dhcp requests. Its been a while since I messed with windows but on the dhcp server there should be a setting of dhcp bootp or both. Select both.

Now lets talk about WDS for a second. A WDS server can use dhcp options 66 and 67 as above, but it can also run a proxy dhcp service that tells the client to ignore the dhcp options and come talk to it for boot information after it gets an IP address for the dhcp server. This maybe called a netboot service or something like that on your WDS server. Its not part of the main WDS service. If this service is still enabled it will override any settings you make in dhcp for pxe booting.

So how do you figure this out to what’s wrong?

The easiest and most complicated issue is to identify what is flying down your network during the pxe booting process. You can do this with wireshark on a witness computer (computer not part of the pxe booting process). This witness computer can either be a ms windows or linux computer, the key is to have wireshark loaded. When you start up a capture use a capture filter of port 67 or port 68 or port 4011 That will limit what wireshark sees to only the dhcp packets. Make sure the witness computer is connected to the same subnet as the pxe booting computer.

Start the packet capture and then attempt to pxe boot the target computer. Continue to capture the packet until the pxe booting computer either reaches the fog iPXE menu or errors out. Then stop the capture.

In the top section you should see the DORA (discover, offer, request, and finally ack/nack) process. The process goes as follows:
Client -> Discovery
Server-> Offer
Client -> Request
Server -> Ack/Nack

In this process you are most interested in the one or more OFFER packets. In a normal network you should only see one OFFER packet. When WDS is involved you will see one OFFER packet from your main dhcp server and a second OFFER packet from your WDS server. If you are seeing the OFFER from your WDS server then you don’t have the proxy-dhcp service disabled, and that is causing your issue. If you are seeing two offer packets from two different dhcp servers, such as a primary / secondary setup make sure both dhcp server are configured to boot from FOG server.

Now what do you do if you only have one OFFER packet and its still not working. This is where you need to select the OFFER packet and then look at the data in the parameters box. There will be the bootp fields of next-server and boot-file these need to be configured for the fog server IP and snp.efi. Then in the dhcp options section options 66 and 67 need to be set correctly. If one or the other sections are not set correctly you will get random machines not booting while others are.

If you can’t figure it out save the packet capture file “be sure you only captured the dhcp process” and up load the file to a file share site and post the link here and one of us will take a look to see what’s wrong. But I think from what I covered here you should be able to figure out what the pxe booting client is being told to do incorrectly.

George,

I ran the idea with the system administrator at my job and of course he was doubtful (conceited), he turned off the server thinking that would solve the issue. I ended up looking at an older forum and made a USB with the ipce file and booted up the machines that were given me issues and that worked. You guys can close this and mark as resolved. Again, I appreciate your guidance on this.

After upgrading to 1.5.10.1754 it works just fine.
Thanks for bug tracking and improvement!

@george1421 I have installed fog with DHCP server but DNS doesn’t work at all (no dns server appear on windows client) so I’m stuck.
It’s my first time installing DHCP and DNS on Debian so I think I made mistakes.
DHCP work fine.

edit : It’s fixed. I forgot to add “option domain-name” and “option domain-name-servers” in dhcpd.conf

For the script, I think it must be simple to set FOG as DHCP server at startup if after 10 min no IP is given from a DHCP server then set server to static IP and start DHCP and DNS services.
And then reverse this at shutdown.
Maybe this can be done manually first.

edit : Here is the first script.
I have create files ending with .dhcp for conf for external DHCP/DNS and file ending with .static for conf for local DHCP/DNS.
It looks to work fine.

# Configuration actuelle echo "Etat DNS local :" systemctl is-active bind9 echo "Etat DHCP local :" systemctl is-active isc-dhcp-server echo "" loc(){ # Configuration DHCP local echo "DHCP local" # Configuration if [ -e /etc/network/interfaces.static ] then echo "Copie interfaces" cp /etc/network/interfaces.static /etc/network/interfaces else echo "interfaces.static not found" exit 1 fi echo "Redemarrage service reseau" systemctl restart networking.service if [ -e /etc/resolv.conf.static ] then echo "Copie resolv.conf" cp /etc/resolv.conf.static /etc/resolv.conf else echo "resolv.conf.static not found" exit 1 fi # Services systemctl start bind9 systemctl start isc-dhcp-server } ext(){ # Configuration DHCP externe echo "DHCP externe" # Configuration if [ -e /etc/network/interfaces.dhcp ] then echo "Copie interfaces" cp /etc/network/interfaces.dhcp /etc/network/interfaces else echo "interfaces.dhcp not found" exit 1 fi echo "Redemarrage service reseau" systemctl restart networking.service if [ -e /etc/resolv.conf.dhcp ] then echo "Copie resolv.conf" cp /etc/resolv.conf.dhcp /etc/resolv.conf else echo "resolv.conf.dhcp not found" exit 1 fi # Services systemctl stop bind9 systemctl stop isc-dhcp-server } # Demande de Configuration while true; do read -p "Voulez vous passer en DHCP externe ou en DHCP local?

@raul I have an Ansible role which does something akin to what you’re trying to do here:
https://forgejo.cwavs.xyz/Cwavs/ansible-role-fog it might be worth taking a look and seeing if it helps give you any ideas on how to solve your problem. Happy to answer questions about it.

@Tom-Elliott Really for the purposes of user tracking. It is helpful for us to keep track of who is deploying and capturing. This is purely for transparency and accountability. I can instruct my team to always register devices they are imaging but I cannot force it.

EDIT: Is there a way to force full reg prior to image deployment? Like a prereq for deployment.
