@Faurel said in PXE over IPv4:
My DHCP server is a VM running Nutanix.
What is your dhcp server? Is it MS Windows based or something else.
Do you know how to run wireshark? I think we need to get a witness computer (a third computer not part of pxe booting). Place the wireshark computer on the same subnet as the pxe booting computer. Use the capture filter of port 67 or port 68 This capture filter will only collect pxe booting information.
What I want to focus on is the one or more DHCP OFFER packets.
Is there more than 1 OFFER packet?
Is the OFFER packet from the correct DHCP server?
Looking into the OFFER packet, in the packet header there are two fields one called {next-server} and {boot-file} are these fields populated?
Look at the dhcp options do you see options 66 and 67? Do they point to the correct values?
If you are unsure of what you are looking at, upload the file to a file share site and post the link here and I will take a look for the common issues.
