      I know this doesn’t technically go in here, but it is part of the process I am following to help resolve this… since I haven’t found what was causing the issues yet, I decided to take the plunge and upgrade to 1.3.0. So I am now running 1.3.0-RC-8 and when my computers boot they are stopping at a screen where it is asking for the address of the tftp server. When I type in the IP address of the FOG server it tries to connect to x.x.x.x/default.ipxe, but the connection is timing out. TFTP was working before the upgrade, is it possible the upgrade changed permissions? Any help is appreciated.

      Thanks!

        That tells me you have more than one DHCP server, and one or more are mis-configured.

        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!

            Ubuntu 14.04.5 LTS

            I have only ever setup one DHCP server. As I stated it is a new build so the settings are exactly what is called for in the FOG setup.

            Option 66 pointing to my FOG Server Option 67 pointing to undionly.kpxe

              @Jay-Bosworth Are you sure there’s no DHCP running on your FOG server?

              Check by

              sudo service isc-dhcp-server stop

                  I ran service --status-all and DHCP doesn’t even show up in the list so I don’t think it is the FOG server. It is somewhere else, still trying to figure out how I can track it down.

                    @Jay-Bosworth How about

                    service dnsmasq status
                    

                    ?

                      Then you might have a rogue DHCP server somewhere.
                      The fact is - the only time anyone has ever reported having to manually enter a TFTP address for FOG network booting - is when there are 2 or more DHCP servers operating on that broadcast domain, and at least one is misconfigured. And we’ve had people ask about this many times. It’s always the same case.

                      This tool explained here would help you:
                      http://www.cyberciti.biz/faq/linux-unix-dhcpdump-monitor-dhcp-traffic/

                      Or you can run wireshark on your desktop with the bootp filter to watch DHCP broadcasts.

                        Also unrecognized, I am close to shutting down the port that the rogue DHCP server is on. I will update once that is done and I test some more.

                          @Jay-Bosworth Rogue dhcp server is confirmed? You found it?

                            Yes, I am pretty sure it belonged to the county health dept who has a satellite office in our district.

                              Thanks to all who participated in this thread. I killed the switch port that someone had a Netgear router hooked up to and everything is working fine now. FOG menu is showing up. I haven’t tried pulling down an image yet, but I have a good feeling. I will do my best to up-vote the proper answers even the earlier posts questioning the possibility of multiple DHCP servers. I had a feeling one was out there, but I didn’t think it would have a such a huge impact on FOG. Again thanks everyone for all the help!
