      @easybizit That is an excellent question!!

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

      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!

        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)
                
                                    JUNIPER (not working)               PFSENSE (working)
            ------------------------------------------------------------------------------------
            server hostname         10.0.5.90                           "not given"
            dhcp option 67          undionly.kpxe                       "not set"
            
            
            
            differences in TFTP read request (client asks the file to the pxe-tftp server)
            
                                    JUNIPER (not working)               PFSENSE (working)
            ------------------------------------------------------------------------------------
            source file             undionly\377                        undionly.kpxe
            in details              undionly\357\277\275                undionly.kpxe
            hexa before "octetsize" ff00                                00
            
            
            
            differences in TFTP server answer (from pxe-tftp server to client)
            
                                    JUNIPER (not working)               PFSENSE (working)
            ------------------------------------------------------------------------------------
            answer                  error code (5) file not found       option acknowledgement
            

            I hope the can be helpfull to you !
