DHCP option 67
-
Good morning all,
After several tries, I cannot configure the DHCP so that it points correctly to FOG.
I put on option 66 the IP address of my server.
And in 67 I tried several boot files (pxelinux.0 and undionly.kpxe) but unable to start on the server (File not found according to the client machine.)
I was also able to try with dnsmasq but without success. I have now uninstalled it.
For info I have the latest version of fog.
Thank you for your answers. -
@FOG38640 Which kind of DHCP server do you use? Probably best if you can provide a picture or config file of the settings your have tried.
Also take a picture of the error on the client machine and post that here. Quite often there is some information hidden in that picture that helps us to guide you the right way faster. Without picture it’s bit like driving through a foggy night.

I am using DHCP from Windows server 2019.
Here is a screenshot from DHCP:
And a screenshot of a machine trying to boot from the network:
For information, the computer capture task is created on the correct MAC address of the machine.Thank

@FOG38640 FYI FOG doesn’t use syslinux (pelinux.0) for booting. If you have a bios system it should be undionly.kpxe and for a uefi system its ipxe.efi.
-
@FOG38640 I assume 192.168.0.168 is you static FOG server IP, right?
As you seem to have tried undionly.kpxe before according to your initial post I am wondering if TFTP is running on your server (
netstat -an | grep 67) and if the files do exist (ls -al /tftpboot/). Run both those commands and post output here. -
@ george1421 I tried the file “ipxe.efi” and “pelinux.0” but it still does not work.
@ Sebastian-Roth
Here is a screenshot of the 2 commands I just performed :
Merci

@FOG38640 Will you run this command
cat /opt/fog/.fogsettingsAll I care about is if it returns data or not. I don’t need to know the data.
If no data the
ls -la /opt/fogwe are looking for a file called .fogsettings If that file doesn’t exist then the FOG Installer did not complete correctly. -
I just executed the 2 commands. Here is their result.
Thank you for your answers. -
@FOG38640 You initial FOG install did not run all the way to the end. Please re-run the FOG installer and make sure it’s finishing.
-
@FOG38640 To add on to Sebastian’s post.
We find sometimes that the FOG Administrator gets instructions to go to the webui to install the database and then forgets to go back to the linux console and press enter to finish the install. The command line installer has 2 parts. They think that when the web ui is up FOG is finished installing, that is wrong.
Rerun the installer again and pick the same options you did the first time. It will not break your system if you rerun the installer at this point to completion. If the .fogsetting file exists then you are done.

@Sebastian-Roth and @george1421
Thank you both very much for your help !! I will have spent a phenomenal time there to resolve the problem.
I will be testing the FOG server on physical computers next Friday when I move into the company.I have so far tested on a hyper-v VM and then yesterday the screen has not changed. I don’t know if this is normal.
I will keep you up to date with the progress.
Thank you

@FOG38640 Hyper-V is a bit of a strange bird. If you get to the initalizing devices then you will have no issues with a physical machine. You just need to be mindful of the target arch of the pxe booting computer and send the right boot file. With hyper-v a type 1 (bios) typically use undionly.kpxe, if that is getting stuck then try ipxe.kpxe. For uefi ipxe.efi is the preferred and the alternate is snponly.efi.

Good morning all,
I am coming back to you after having been able to test the fog server on real machines. These all have catch spots. I tried with multiple conf files in DCHP option 67 but got an error message.
Here it is :
Is there something to do?

For information 192.168.0.54 is a dhcp server (Windows server 2019)

My kernel is up to date and fog to the latest version 1.5.9
What was your message?
-
@FOG38640 This issue isn’t related to pxe booting. This is something in fos linux. I would recommend you update to the latest kernel (fog configuration -> Kernel update).
Lets confirm a few things too.
Is your fog server at 192.168.0.54?
Can you access the fog server athttp://192.168.0.54/fog?
What network adapter is in this target computer?According to the messages this should be working. We have seen some realtek nic behave a bit odd on occasion.

@FOG38640 said in DHCP option 67:
My kernel is up to date and fog to the latest version 1.5.9
This does not mean you have the latest kernel. There was a new kernel released right after 1.5.9 was released. The 1.5.9 release used 4.19.143 and the updated kernel is 5.6.18,

The address 192.168.0.54 is the address of the DHCP server (Windows server).
The address of fog is 192.168.0.168.
The computer’s network card is an Intel Gigabit. -
There is nothing in the kernel version.
