Re: [Dnsmasq-discuss] About UEFI PXE booting in proxy mode

Hi Doug, Thanks. Simon mentioned to me: This is complicated and horrible (to implement the mechanism). Therefore for the moment, no any solution for using "pxe-service" for both uEFI network booting and PXE in proxy mode I believe. Steven On 2017/04/01 12:39, Doug Brown wrote: > HI Steven, >

HI Steven, No -- because of grub's current inability to detect a proxy boot with UEFI, I don't think it's possible to get a proxy configuration to boot UEFI computers with grub, unless you play around with grub-mkstandalone to embed grub.cfg into grub.efi. I haven't had the time to play around

Hi Steven, If I find some free time, I might try tracing through the code to figure out why dnsmasq is throwing out the DHCP packets on port 4011 in the EFI + PXE configuration without a proxy. In the meantime, here is the configuration that works for me with dhcp-boot (assuming my dnsmasq

Hi Doug, Thanks for your explanation. Simon also emailed me after my post and let me know where the problem is. The conclusion is this issue seems not be easily fixed. So the patch for grub will be applied after grub 2.02. Before that, could you please show me the configuration file you

Hi Simon and Steven, I just found this recent thread while I was Googling for the exact same problem (UEFI clients won't boot in PXE mode, but BIOS clients will) and there was never any conclusion reached. I'm running into the exact same problem, and I can provide a pcap dump, which I have
