      I checked and the bios is old (A11) vs current A15. I’m going to update the firmware after a bit to see if that is what is causing iPXE to not init right. I can say it works flawlessly in bios mode.

      Would you be able to service this exact same ipxe.efi binary using isc-dhcp just to see if it makes a difference? My guess is no but you never know.

      Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

      Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

        @Sebastian-Roth I think my next step is to first update the bios on this computer from A11 to A15. The change log for these updates many uefi updates and hardware (nic and such) firmware updates. I want to make sure I’m not chasing something that has already been addressed. I have 2 issues with getting this done: 1) This computer runs Zorin (ubuntu variant) and the firmware updates are windows based. I have a WinPE flash drive at work that we use to update the computer bios at work. I need to make a copy so I can use it to update this 6230. 2) This is my wife’s computer, if I break it I will never hear the end of it. So I need to be spot on with the upgrade if you know what I mean.

        Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

          @george1421 I was finally able to update that 6230 from firmware A11 to A15. Without changing my FOG-Pi / dnsmasq setup the 6230 now pxe boots in uefi mode (whoot!!). The kernel stayed at initializing devices for about 15 seconds, I started to panic after 8, I figured it was hung and reach for my FOG GRUB usb boot drive. When I turned around the 6230 was sitting at the FOG iPXE Menu. I timed it again and it was bout 15 seconds to init the devices and display the FOG iOXE menu. I was able to quick register the system and everything worked fine.

          Below is my final dnsmasq configuration for dual booting bios (legacy) and uefi systems on dnsmasq version 2.76

          # Don't function as a DNS server:
port=0

# Log lots of extra information about DHCP transactions.
log-dhcp

# Set the root directory for files available via FTP.
tftp-root=/tftpboot

# PXE menu.  The first part is the text displayed to the user.  The second is the timeout, in seconds.
pxe-prompt="Booting FOG Client", 1

# The known types are x86PC, PC98, IA64_EFI, Alpha, Arc_x86,
# Intel_Lean_Client, IA32_EFI, BC_EFI, Xscale_EFI, ARM_EFI and X86-64_EFI
# This option is first and will be the default if there is no input from the user.
# PXEClient:Arch:00000
 pxe-service=X86PC, "Boot BIOS PXE", undionly.kpxe
# PXEClient:Arch:00007
 pxe-service=BC_EFI, "Boot UEFI PXE-BC", snp.efi
# PXEClient:Arch:00009
 pxe-service=X86-64_EFI, "Boot UEFI PXE-64", snp.efi

dhcp-range=192.168.112.24,proxy

          According to the change log for dnsmasq there are issues with certain uefi firmware for displaying the dnsmasq boot menu so for uefi firmware dnsmasq will just pick the first matching service entry that matches the arch type, as long as there is only one and only matching service. You will not see this menu displayed for uefi firmware, where for bios you will see the menu entry for 1 second.

          I did note in the iPXE bootloader that it did say duplicate next server values presented (or something like that). And that is in line with what we were seeing in the earlier pcap where both dnsmasq and the soho router were sending conflicting next-server values.

          Here is the pcap of my last and working test. Note: I see I left the snp.efi kernel configured in dnsmasq too!!.

          0_1475719888587_output.pcap

            @george1421 Last and final comment. Just for grins, I move the original Raspian Jessie version of dnsmasq (v2.72) back in place and restarted dnsmasq. With 2.72 running and the same configuration as before the Dell 6230 failed to pxe boot in UEFI mode, but would boot in bios (legacy) mode. So if you are going to use dnsmasq AND require pxe booting uefi systems you must upgrade dnsmasq to 2.76 or it will fail.

              Hi,
              I was just wondering if you actually got this to work in proxy mode? I have tried and can seem to get it to UEFI boot in proxy. I tried setting dnsmasq to serve as DHCP for a moment(and unplugged from rest of network) with just my test client and Fog/PXE and that worked. Was able to get to Fog menu.

              Using dnsmasq 2.76 and just pulled latest fog rc36.

              Do I need to compile something differently that I’m not seeing(it’s posible I missed something)? Or does it just not work in proxymode at this time?

              thanks,
              Jason

                @KnightRaven Yes dhcpProxy mode works very well as long as you have 2.76 version of dnsmasq.

                Post what your ltsp.conf files is here. I’ll take a look.

                Also from the fog server command prompt key in dnsmasq -v and post the output here

                    @KnightRaven OK what I want you to do (speaking as a moderator now) please create a new thread on this issue. and also include the contents of your /etc/dnsmasq.d/ltsp.conf file. We’ll carry on the discussion there.

                    But your dnsmasq version should/will work for what you want to do.

                      0_1481838650169_ltsp.conf

                      I’m about to be out for the day so I may not get a chance to test for a few weeks. The file may also be a bit ugly but i tried to leave as much of the original info in and just updated info as needed.

                          @KnightRaven Yeah, I see the issue right away. When you are back on this project create a new thread and we can work through what needs to be done. You are missing a few lines that make the uefi bit work.

                            hi, when saw dnsmasq maillist http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2017q2/011379.html

                            3q for https://github.com/openSUSE/kiwi/wiki/Setup-PXE-boot-with-EFI-using-grub2 & https://www.ibm.com/developerworks/community/blogs/a2674a1d-a968-4f17-998f-b8b38497c9f7/entry/uefi-grub2?lang=ru

                            the problem may not in dnsmasq, when update to version 2.76. uefi boot can see grub>

                            My env is all in VMware Workstation 12 Pro 12.0.0 build-2985596
                            NAT mode

                            dhcp to cobblerctos73(legacy bios)
                            dhcp to uefi(efi)

                            1. 136.200 install dhcpd
                              conf file like blow
                            dns-update-style interim;

     max-lease-time             43200;
}
                            1. 136.226 install centosbase dnsmasq then upgrade to 2.76 from souce, see
                              https://wiki.fogproject.org/wiki/index.php?title=ProxyDHCP_with_dnsmasq#Compiling dnsmasq 2.76 if you need uefi support

                            It’s not perfect.
                            Cuz in grub.cfg we need write nextserver ip & host ip,
                            And grub2-mkstandalone command write grub.cfg in bootx64.efi, cuz I change boot/grub/grub.cfg it’s. not working.
                            So now I working to grub lib, want find way to solve this 3 problem.

                            If anybody working with grub/grub2, can give me some idea? thank you very much.***

                                  @xutianhong I’m not sure I follow. Grub and rEFInd are exit types, to leave pxe and boot to HDD.

                                    If you’re simply trying to boot an iso, ipxe supports this natively.

                                          @xutianhong Can you explain what your trouble is? I read your first post and it was not clear, I think maybe the language translation.

                                          Your first post make me think you are telling us what you find not asking for help.

                                            @george1421 ok. i was using cobbler install redhat @ my work env. at first i found all works fine @ legacy bios. but when shift to UEFI. its’ not work good anymore. cobbler+dnsmasq.proxymode, msg freeze at option 47. i search google and found fog.wiki have advice dnsmasq need upgrade to 2.76. i do it. at this time , screen show grub>. then i search @ dnsmasq mail list and other website. find some way to figure this write in my first post. but it’s need write static ip&nextserver info to cfg, make standalone efi file. then Tom Elliott suggest ipxe & rEFInd.
