Hello, I’m sorry for my poor English, i’m french. I will explain as detailed as i can I’ve installed FOG 1.2.0 on a Debian 8 virtual machine, no problems i can access the web interface to add my two “test” hosts. FOG is not used as a DHCP server in my configuration. On my domain controller, i’ve created a strategy with my 2 test mac addresses who force options 66 et 67 to undionly.kpxe et and fog server IP. When i go on “Hosts” in fog web interface, it does a “mac ping” on my two hosts and it appears to be “UP” But, when i reboot my 2 test computers on “NIC boot”, it contact the DHCP server, takes an IP, then failed to load “TFTP” and nothing shows me that these contact the FOG server… Fog would be very useful in my company, i need your help !! Thanks Arnaud

Interesting post! Great that you got it as far as iPXE being loaded from TFTP. iPXE itself does another round of DHCP to be able to communicate and load things like the kernel or menu via HTTP. You wonder why this is not working if DHCP does work on the first run before iPXE. Spanning tree settings on your switch might be an issue here. But quite often this would cause an issue earlier on already. But you can still try setting “port fast” on this switch port where your client is connected. Newer versions of iPXE are better at handling this. But not the one coming with FOG 1.2.0 AFAIK. I really love diving into a PCAP dump as this is right down to the details. I don’t need to guess what’s going on. I just see it. I am more than happy to have a look if you upload a PCAP file! Wireshark filter bootp && tftp is great for this (or port 67 or port 68 or port 69 if you are using tcpdump)…
