      @easybizit It looks like I forgot to include this, I dreamed it, or thought and the forgot it.

      Using a windows computer (for windows install the tftp application) or another linux computer. Use tftp and attempt to download the undionly.0 file from the fog server. That will test to see if the file “could” be acquired by the target computer. It bugs me that it “should” be working, but is not.

      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 Hi! Sorry, my boss send me on a three week escapade with a days notice, I’m back now. Eureka! I think we may have found the problem. I can tftp many files but not the undionly.0 file. See below:

        0_1492915734649_undionly failure.jpg

        How do I fix that? Could it be permissions on the other side of the sym link?

          @easybizit You do need to create the symbolic link between undionly.0 and undionly.kpxe for that bit to work.

          ln -s /tftpboot/undionly.kpxe /tftpboot/undionly.0
          ln -s /tftpboot/ipxe.efi /tftpboot/ipxe.0

            @george1421 Here is the contents of the tftpboot directory (just resnapped it):

            0_1492916346293_tftboot folder.PNG

            Does this look right?

              @easybizit yes that looks correct.

                @george1421 hmm… So why won’t it grab the file on PXE boot? I’m afraid I’m not strong in this area but I get the feeling that there something really silly that I’ve missed.

                  @easybizit can you download the file manually via tftp?

                    @george1421 I can grab the undionly.kxpe but not the undionly.0. ‘I get connect request failed’

                      @easybizit Well that one is a bit confusing. I’m not seeing anything wrong.

                      Lets replace the link with a real file.

                      cp /tftpboot/undionly.kpxe /tftpboot/undionly.0
                      

                      And then try with the tftp again from a remote windows client.

                          @easybizit That is an excellent question!!

                          Has selinux been set to permissive? The sym link should work no problem…

                            Here is the latest copy (I rebuilt the box to a different environment but had the same issue this is the latest copy, hence I think I’ve done something dumb).

                                I had exactly the same problem with some old pc/laptops (i.e. hp probook 4411s) but not on recent pc

                                • fog 1.3.0rc8 on debian
                                • the dhcp server was handled by a juniper switch ex3300 junos 12.3R10.2
                                • made some test with a pfsense vm v2.3.2 acting as a dhcp server

                                When I captured packets on the server, I noticed that the client was requesting a files that did not exist so I decided to mirror the port and capture the complete process as I was expecting something with the dhcp

                                the main difference seems to be that the juniper dhcp includes the filename in the option 67 (in addition of being also in the "boot file name¨ ) and pfsense doesn’t, and some legacy computer seems to not handle that properly and adds some caracters at the end of the filename which make the tftp request wrong which makes the tftp server to not understand what file is requested

                                here’s my notes from the captures

                                differences in dhcp offer (dhcp answer to the client)
