@george1421 So with 2.76 is your pxe booting for uefi working as you need it?
Don’t follow this just yet, posting it cause I’m doing 4 things right now and don’t want to loose the link.
ref: https://forums.fogproject.org/topic/9673/when-dhcp-pxe-booting-process-goes-bad-and-you-have-no-clue -
UEFI is not working. Only BIOS booting works as intended. When I look in the syslog it shows that there is communication, the client just doesn’t push to the FOG bootup.
-
@Merilious is the uefi iPXE kernel making it to the target computer (i.e. are you seeing the iPXE banner)?
If you are unsure where to turn next, then follow and do what the tutorial says in the previous post. What we need to do is capture the pxe bootup of one of these uefi systems. This works really well if the fog server and the pxe booting client is on the same subnet. Post the pcap here for review.
I can boot and image a BIOS system no problem. It’s UEFI/EFI systems that don’t want to work
for clarity a clear picture taken with a mobile phone helps understand what don’t work means. If we can see the error we may understand what’s wrong. The context of the error is almost as important as the error itself.

That 2nd snip took a little ingenuity to capture lol. Had to use the slow-mo video feature on the galaxy s7. Thanks for the help thus far. I feel like I’m on the right track, just need to fix a few nub errors I may have configured or not configured yet maybe.
-
@Merilious ok that tells me a bit more about the booting process. Everything looks good until it talks to the ProxyDHCP server (dnsmasq). So we need to move to step 3 for dnsmasq config.
after this section in your ltsp.conf
# PXE menu. The first part is the text displayed to the user. The second is the timeout, in seconds. pxe-prompt="Booting FOG!", 10Actually take the prompt timeout from 10 to 1. Its not needed since you can’t pick anything different in this configuration.
add in
pxe-service=X86PC, "Boot to FOG", undionly.kpxe pxe-service=X86-64_EFI, "Boot to FOG UEFI", ipxe.efi pxe-service=BC_EFI, "Boot to FOG UEFI PXE-BC", ipxe.efiI guessed at the context since I can’t find it quickly. I have the answer on my dev server at home, but well that’s at home and I’m not.
If that doesn’t work then move to step 4
pxe-service=X86PC, "Boot to FOG", undionly.kpxe,10.200.10.20 pxe-service=X86-64_EFI, "Boot to FOG UEFI", ipxe.efi,10.200.10.20 pxe-service=BC_EFI, "Boot to FOG UEFI PXE-BC", ipxe.efi,10.200.10.20We don’t want to jump right to 4 because it may create other issues. So one step at a time. This should tell proxy dhcp to send the right file name per the client request.
-
Right after this it booted right to the FOG menu! Did a quick registration and verified FOG picked it up in the web portal. So awesome! If you don’t mind me asking, why did this work?
-
@Merilious Some environments require the pxe-service code and some do not. I don’t have a solid answer for you, but we start and step 1 and move to step 4 testing at each step. Your pcap file was flowing perfectly until it got to the proxydhcp dialog. dnsmasq didn’t supply what your PXE rom needed so it abort the pxe boot. This is all different pxe rom requirements. Once you are in iPXE then fog has a better chance of controlling the pxe booting process.
Ah ok, I just reread what iPXE posted, duplicate option 66… your dhcp server gave it one IP address for the boot server and dhcp proxy gave it another so it talked to the proxy to find out what to do. I need to look at your pcap file again a bit closer to see where your main dhcp server was sending the client. Do you have another imaging system in your environment?
-
I have my Parallel VM’s. Just tested the EFI boot on it and it worked great. Exact same message about the duplicate DHCP. Unfortunately I’m out for the weekend as of this post so if you don’t hear anything from me until Monday… I REALLY appreciate the help. Any further information you need just ask and I’ll post first chance I get. When I saw the duplicate info notice I asked our network guy if the Next-Server entry happened to still linger but it was not.
-
@Merilious Great to see that you guys figured this out already. Well done George! Thanks for posting the PCAP and pictures as well. Looks like our iPXE script (see here) is not behaving the way we intended it to. I am not sure if this a general issue or just caused by the UEFI firmware you have.
Should be save to ignore in your case as far as I can see in the PCAP file there is no next-server/option 66 sent by your main DHCP server.
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)

Well that may explain why I didn’t see the main dhcp server responding with next server. I was going to have the OP post his ltsp.conf again on monday to see if we had something in the wrong spot and/or capture another pcap file. We might want to do that just to be clear that dnsmasq isn’t doing something unexpected.
-
Alright I’m back (a day late). We’re trying to move fast with this so I’ve gone ahead and began building the FOG server on our production side. Again though, I’m stuck on breaking DNS once DNSMasq is installed. I don’t remember how I got around this before to do the DNSMasq build/upgrade to 2.76 unfortunately…
You had mentioned disabling dnsmasq from taking over DNS through ltsp.conf. Here is my current running ltsp.conf:
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 # Disable re-use of the DHCP servername and filename fields as extra # option space. That's to avoid confusing some old or broken DHCP clients. dhcp-no-override # inspect the vendor class string and match the text to set the tag dhcp-vendorclass=BIOS,PXEClient:Arch:00000 dhcp-vendorclass=UEFI32,PXEClient:Arch:00006 dhcp-vendorclass=UEFI,PXEClient:Arch:00007 dhcp-vendorclass=UEFI64,PXEClient:Arch:00009 dhcp-match=set:ParallelsEFI,97,00:ef:e3:6d:16:10:6f:46:9d:87:12:5a:12:c2 # Set the boot file name based on the matching tag from the vendor class (above) dhcp-boot=net:UEFI32,i386-efi/ipxe.efi,,10.100.10.22 dhcp-boot=net:UEFI,ipxe.efi,,10.100.10.22 dhcp-boot=net:UEFI64,ipxe.efi,,10.100.10.22 dhcp-boot=tag:UEFI,tag:ParallelsEFI,intel.efi,10.100.10.22,10.100.10.22 # The boot filename, Server name, Server Ip Address dhcp-boot=undionly.kpxe,,10.100.10.22 # PXE menu.

[main] plugins=ifupdown,keyfile,ofono [ifupdown] managed=falseI noticed that I get a new connection named en32 when I install DNSMasq (or somewhere along the lines of installing FOG and DNSMasq). I went in that connections settings and saw 127.0.0.1 as the DNS entries so I updated them to our proper DNS entries, reset networkmanager and dnsmasq services, but still could not ping google but 8.8.8.8 pinged fine. Any ideas?
-
@Merilious if your DNS is behind a domain you may need to add the domain name to search from. Just a theory no real clue though.

port=0
It looks like @Quazz has a solution for this here: https://forums.fogproject.org/topic/7193/ubuntu-14-04-lts-with-dnsmasq-no-external-dns/8
I did a little research on this and specifically the command “port=0” and its working as designed (??). From Quazz’s post it looks like you just need to adjust the dnsmasq startup scripts to not throw 127.0.0.1 into the resolv.conf file.
-
So that did the trick! I added that line and got both EFI and BIOS to boot up to FOG. One thing always needs to another though…
I tried doing a quick registration for each BIOS and EFI. BIOS goes through just fine, but the EFI gets stuck at bzIMAGE… 0%. I tried going in to the FOG web portal and updating the kernel but it still won’t budge. Any ideas?
-
@Merilious said in Dell Inspiron 15 7559:

This is an issue with (around) the iPXE kernel for efi. What file name are you sending for a efi system? ipxe.efi?
If so, for grins try this iPXE kernel instead: ipxe7156.efi Sometimes we’ll find hardware with flaky firmware (not so much Dells). Also make sure your firmware is up to date on that device.
-
I tried both the ipxe7156.efi and the intel.efi. Both had the same effect. Looked in the syslog and here’s the print out of one of the attempts. Just for verification I went in to the ltsp and changed all bootfile options to either the ipxe7156.efi or intel.efi. The one thing that pops out a little is the line saying

So I’ve gone through all the combos that I could find between the boot files found in tftpboot and the NICs provided by the Parallel VM options.
Bootfiles tried:
intel.efi
intel7156.efi
ipxe.efi
ipxe7156.efi
realtek.efi
realtek7156.efi
snp7156.efi
snp.efi
snponly.efi
snponly7156.efiNIC options:
Intel PRO/1000 MT
Intel Gigabit CT (82574L)
Realtek RTL8029AS
Virtio network adapterSome would fail to get to the FOG boot screen. Most would get the previously stated bzIMAGE… 0 to 1%. A few got slightly further but would fail at this part:
-
@Merilious So just to be clear this issue is with your Parallel VM and not with the Dell?
-
For now yes…I shamefully forgot my Dell test laptop at home. That’d be the big test to see if I can get that to register with FOG. Will post here soon as I get that test done. Thanks a bunch for all the info!
