@joyboy11111 I personnally think it would be quicker to just update the pxe boot file to see if that addresses the issue.

But it you want to update fog, it looks like you might have the git install files in that screen shot. So change into the fogproject directory then issue the following command git pull that should update the installer files. Then change into the bin directory and run ./installfog.sh script. It should remember the settings you made the last time you installed fog. The installer will stop half way through asking you to go to the website and update the database. Then don’t forget to go back to the linux console to finish the install.

So I use wget github.com… and download both files to var/www/html/fog/service/ipxe? Will that unzip and copy and replace the files in that directory?

george1421

@joyboy11111 The files are not zipped, you can directly download them using your computer and then transfer to the FOG server if you want to go that way too.

Or from the linux console

wget https://github.com/FOGProject/fogproject/raw/master/packages/tftp/undionly.kpxe

and
wget https://github.com/FOGProject/fogproject/raw/master/packages/tftp/ipxe.efi

Those files are in the snap shot below. I tested, made sure both MAC’s were deleted from hosts. Did a quick registration and it did the same thing. Pulled the MAC of the adapter. Still shows has host not registered.

Did I do something wrong?

george1421

@joyboy11111 I don’t think you did anything wrong, just updating ipxe didn’t solve the problem.

So what device is your dhcp server?

joyboy11111

@george1421
Does this give you the info you need? I use multiple adapters, eht0 is assigned to FOG. ETH1 is how I let FOG get out to the internet.

george1421

@joyboy11111 OK so to answer my question, you use the FOG server as the dhcp server for your FOG imaging network. So you need to edit your dhcp server configuration file.

Replace these parameters filename "ipxe.efi" with filename "snponly.efi" then restart your dhcp server. Lets try the snponly.efi boot loader. Lets see if it finds the right mac address.

joyboy11111

@george1421
I renamed the ipxe, and downloaded snponly. Tested with the same issue. I feel i am doing something wrong.

george1421

@joyboy11111 Ok I think we need to regroup because we somehow have moved off course.

You are using the isc-dhcp dhcp server on your FOG server. So what I’m recommending is that you go into the configuration file for the isc-dhcp server and change the references from ipxe.efi to snponly.efi, then restart the isc-dhcp server.

I’m going to assume you are running debian/ubuntu variant so these instructions will help you: https://help.ubuntu.com/community/isc-dhcp-server

The fog installed configuration file for the isc-dhcp server looks similar to this: https://wiki.fogproject.org/wiki/index.php/BIOS_and_UEFI_Co-Existence#Example_1

OK so to my thoughts. The ipxe.efi boot loader is much like an operating system itself where it will have a hardware driver for every common model of network adapter. The snponly.efi boot loader is much like the undionly.kpxe bios boot loader in it only contains one network driver which speaks to the network driver built into the network card. The idea is that maybe there is a bug in the ipxe.efi boot loader driver for that nic, where the driver built into the network adapter would respond correctly.

There is something uniquely special about that network adapter to why it is reporting a different mac address for iPXE vs linux and windows.

@joyboy11111 In the picture it looks like you put the downloaded iPXE files in /var/www/html/fog/service/ipxe/ but that place is for kernels and inits but not for the iPXE files! Put those in /tftpboot/ (default when you use the FOG installer).

joyboy11111

@george1421

I am very sorry it has taken me this long to get back. Several other issues came up that I needed to address.

If I am in the correct place the dhcp config file is empty. I am very sorry I am so reliant on you for step by step instructions.

is Sebastian correct in his post below also?

george1421

@joyboy11111 No that is not the config file for the dhcp server, that is like the startup options file.

I had to look it up because centos 6 is so long ago. But it looks like the config file is /etc/dhcp/dhcpd.conf

ref: https://www.server-world.info/en/note?os=CentOS_6&p=dhcp

I am a bit surprised that FOG 1.5.x installs on centos 6. But if it works, go with it.

@george1421
What line would I make the change from ipxe to snponly.

Tom Elliott

@joyboy11111 I’m going to guess, and no judgement intended please, that you’re not overly familiar with VI/VIM for editing file?

type these commands:
/ipxe.efi

Press enter

Note the/ = search everything after.

Once you find the line line arrow over to the area to edit and press the i key, Press delete over the ipxe.efi then type snponly.efi

Note the i = insert to leave “insert/edit” mode press ESC key

Press the esc

Type :w

Note the : puts VI into "command mode. w = save/write file.

To exit VI type: :q

Note the : puts the VI into "command mode. q = quit.

george1421

@joyboy11111 If the FOG installer created the dhcp server configuration it should look similar to this: https://wiki.fogproject.org/wiki/index.php/BIOS_and_UEFI_Co-Existence#Example_1

If you scroll down in the screen shot you posted you will see this section

    class "UEFI-64-1" {
    match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00007";
     filename "ipxe.efi";
    }

    class "UEFI-64-2" {
    match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00008";
    filename "ipxe.efi";
    }

    class "UEFI-64-3" {
    match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00009";
     filename "ipxe.efi";
    }

so for the uefi-64 entries you want to change filename varialble to snponly.efi

joyboy11111

@george1421

There is nothing below Filename “undionly.kpxe” just blank. I tried to the search from tom /ipxe.efi, nothing, no results. should I copy and past those lines from the wiki for the rest of the config file?

george1421

@joyboy11111 Did someone hand edit that file? I find it strange that it doesn’t match the fog supplied configuration file.

You can remove that static filename stanza line and insert the class definitions from the wiki page. Then reboot the dhcp server.

The ways its currently configured that dhcp service will only support booting bios based computers via PXE.

joyboy11111

@george1421 It does give me a warning about a swap file when I go to view the config.

george1421

@joyboy11111 So the file may have been open with vi or nano when the computer was rebooted or you have the file open in another session on the server. If the swap file was created previously before a reboot you can delete the file. In the same directory as that file there should be a .swp file. You can remove that file so you won’t get that nuances message.
