      @FrancoDin The best path to take is disable dhcp server on your FOG server.

      I’m a RHEL guy so I’m guessing at these commands.

      # stop the isc-dhcp server
      sudo service isc-dhcp-server stop 
      # Uninstall isc-dhcp server
      sudo apt-get remove isc-dhcp-server
      

      The next step is to update your router to add the boot file settings into your router. From the second error message it appears the router is selecting itself as the boot server.

      What you need to do is update dhcp option 66 {next-server} on your router to point to your FOG server’s IP address and then update dhcp option 67 {boot-file} to undionly.kpxe for bios based systems or ipxe.efi for uefi based systems.

      If your router doesn’t support netbooting / pxe booting then we can move on to plan B. Either plan required that you stop and uninistall the isc-dhcp server from your fog server.

      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!

          @FrancoDin Ok then for plan b.

          I want you to install the DNSMASQ service on your FOG server.
          sudo apt-get install dnsmasq

          We will use dnsmasq to “override” what your dhcp server is telling the clients to boot from.

          Once dnsmasq is installed inspect /etc/dnsmasq.d directory. There shouldn’t be any files in that directory. We need to create a new one called ltsp.conf.

          Paste the following into that file

          # 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
          
          # The boot filename, Server name, Server Ip Address
          dhcp-boot=undionly.kpxe,,<fog_server_IP>
          
          # 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
          
          # Set the boot file name based on the matching tag from the vendor class (above)
          dhcp-boot=net:UEFI32,i386-efi/ipxe.efi,,<fog_server_IP>
          dhcp-boot=net:UEFI,ipxe.efi,,<fog_server_IP>
          dhcp-boot=net:UEFI64,ipxe.efi,,<fog_server_IP>
          
          # 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 and X86-64_EFI
          # This option is first and will be the default if there is no input from the user.
          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.efi
          
          dhcp-range=<fog_server_ip>,proxy
          

          Don’t forget to replace <fog_server_ip> in the above text with the IP address of your fog server. The tag appears many times.

          Then issue the following commands to:

          # enable dnsmasq to start every time
          sudo systemctl enable dnsmasq
          # restart the dnsmasq service to pick up the new config files
          sudo systemctl restart dnsmasq
          

          Make sure before you install dnsmaq you already disabled and remove isc-dhcp server from the previous post. Both services use the same network ports.

          pxe boot your target computer and see if you can get to the FOG iPXE menu.

              @FrancoDin Can you confirm that dnsmasq is running in memory.

              sudo ps aux|grep dnsmasq

              I’m also not seeing it pick up a dhcp address. Is the target computer on the same subnet as your dhcp server? Your Mikrotik is your normal dhcp server right?

                The target computer is in the same subnet as the dhcp server, and yes the mikrotik is the normal dhcp server.

                  @FrancoDin well from the screen shot I don’t see dnsmasq running.

                  sudo systemctl start dnsmasq

                  then make sure it starts every reboot
                  sudo systemctl enable dnsmasq

                  Also lets capture the version of dnsmasq to make sure its 2.76 or newer
                  sudo dnsmasq -v

                    @FrancoDin I also see from the screen shot you are editing the /etc/dnsmasq.conf file. This file should not be adjusted. It should have a reference to load any files in the /etc/dnsmasq.d directory. The dnsmasq.d directory is where the ltsp.conf file goes.

                    Also, is your FOG server running on virtual box? If so, you need to ensure you are using a bridged network adapter for both the fog server and pxe booting client. Using a nat network adapter will cause you pains trying to get things to pxe boot.

                      So its fail at running, and the version of dnsmasq is 2.75
                      I am editing that file whit nano, because I am using Putty, and I cant coppy paste files in the ubuntu server at the moment. The fog isent runing in virtual box.

                      I just realized the error is in spanish, sorry my bad, that red line says:
                      Rank of dhcp not valid, in line 26 of lstp.conf
                      Fail at the start

                        @FrancoDin well I can see from your screen shot that you have extra text in the config file. <10.0.0.2> should be 10.0.0.2 (assuming that 10.0.0.2 is your FOG server’s IP)

                        PS: Look at the FOG Forum chat bubble for additional hits

                          Now it works, but when I go to the PC and boot:

                          Auto-Select:
                          Boot to FOG

                          BOOT Server ip:10.0.0.2
                          TFTP.
                          PXE-T01: File not Found
                          Pxe-E3B: TFTP Error - File not found
                          PXE-M0F: Exiting intel PXE ROm.
                          Fatal: Could not read from the boot medium

                          Also I see that maybe there is a problem in the IP, because there is another device whit the ip 10.0.0.2 so I will fix that tomorrow and tell you what happen

                            fwiw: In a previous post you had the fog server at 10.0.0.27

                            Also the fog server must have a static IP address or one created via dhcp reservation. FOG does not fog support servers that are configured to use dhcp. Your fog deployment will break if the IP address of your fog server changes after FOG is installed.

                              Yhep, that broke the fog.
                              But I managed it, to update the dnsmasq, after manually instaling 80 packes from https://www.debian.org/distrib/packages , that seems to work for the pxe boot error, but it direct me to my previous IP, so I will reinstall ubuntu server, and try all again, because I try to reinstall fog, but have a problem deleting it and when try to reinstall its gets an error instalin packges,(maybe I broke that aswell).

                                @FrancoDin Well if you want to go through the process again, just make sure that the FOG server has a static IP address before you install FOG. Just install a normal FOG server without dhcp services.

                                Then install dnsmasq and use the config file I provided. (hint: if you are using putty to connect to your fog server, you can use copy and paste to copy the text file into nano and ltsp.conf easily).

                                Once dnsmasq is setup correctly using my config file it should work. If not then we will use the fog server and tcpdump to capture what is going wrong with the pxe booting process. We are far from just giving up. This WILL work.

                                  Thank you a Lot, all working now.
                                  Just one think, I follow this guide (https://forums.fogproject.org/topic/10944/using-fog-to-pxe-boot-into-your-favorite-installer-images/9) to add Linux Mint, to the fog menu. But when I boot from there Its says “Connection time out”, its has anything to deal whit dnsmasq?

                                  Also, in the parameters:
                                  kernel tftp://${fog-ip}/mint/18.1/vmlinu
                                  Should go like this
                                  kernel tftp://${10.0.0.7}/mint/18.1/vmlinuz
                                  or
                                  kernel tftp://$10.0.0.7/mint/18.1/vmlinuz
                                  in the 3 different times its appears.

                                    @FrancoDin said in 2 Error in iPXE (time out and sand device):

                                    kernel tftp://${fog-ip}/mint/18.1/vmlinu

                                    If you use the fog parameter ${fog-ip} that will be replaced by the actual IP address of the fog server. That makes the fog menu entry portable between different fog servers.

                                    Also be aware that you typed in your post
                                    kernel tftp://${fog-ip}/mint/18.1/vmlinu

                                    I hope its just a type-o but you missed the z on the end
                                    kernel tftp://${fog-ip}/mint/18.1/vmlinuz

                                    Back to your question you can also enter it as this:
                                    kernel tftp://10.0.0.7/mint/18.1/vmlinuz

                                    In programming terms the ${ } denote a variable used in the iPXE menu. Where the variable name is between the curly braces.

                                      Also… why the route is
                                      kernel tftp://${fog-ip}/mint/18.1/vmlinuz
                                      when actually the vmlinuz is in /tftpboot/mint/18.1

                                        But when I boot from there Its says “Connection time out”, its has anything to deal whit dnsmasq?

                                        If you are seeing the FOG iPXE menu then the issue is beyond dnsmasq. If you didn’t see the FOG iPXE menu then we would focus on the dnsmasq settings.

                                        I’m suspecting that there is something wrong with the custom iPXE menu you created or the needed files are missing.

                                        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!

                                          Also… why the route is
                                          kernel tftp://${fog-ip}/mint/18.1/vmlinuz
                                          when actually the vmlinuz is in /tftpboot/mint/18.1

                                          well this will become clear when you know that the tftp server’s base directory is /tftpboot. Just like the http server’s base directory is /var/www/html/. And the nfs servers base export directory is /images on the fog server. So knowing what tranfer protocol you want use, you would place the files in the correct base file directory.

                                          Your menu entry is using the tftp protocol so your base directory is /tftpboot. I can tell you that tftp is the slowest protocol of the three. Depending on how you want to use this configuration you might want to change some things. If its just a test or something you use once a month its fine. But for now get it working then improve on what you have once its works.
