@Sebastian-Roth Thank you for your feedback! I found the solution the dnsmasq file had just the ip of the server in dhcp-range without the subnet. So I adjusted the line dhcp-range=192.168.0.23,proxy to dhcp-range=192.168.0.23,proxy,255.255.254
Thanks for the feedback, sorry for my late response.
Hi,
I’m using a fogserver in some schools for more than 3 years. Works perfectly sometimes a few hiccups but always been able to solve this. At the moment I encounter a strange problem with some computers. They are all the same (BIOS, Motherboard,…) but some can connect to FOG (BOOT) others not I receive an error “PXE-E78 Cannot locate boot server”.
I notice that the computer connects to the FOG server and it is showing the message “Booting FOG Client via DNSMASQ-1” (from the DNAMSQ.D file). Content:

We are using a Windows DHCP with no options configured and the DNSMASQ on the fog 192.168.0.23. One subnet same computers with same motherboard and network card Realtek 8111F, 1 x Gigabit LAN Controller(s) with Realtek PCIe GBE Family Controller Series v2.46 (03/23/12).
What I don’t really understand is why does it work for the same model of computer with the same BIOS settings etc and for some not…
Thank you!
