    @george1421 You seem to understand the problem exactly. You are also correct that the server itself, the client, and the DHCP server are all on different vlans. This is important to the way our network is set up, and i really need this to be able to work across vlans. If it matters, i could move the fog server to the same vlan as the DHCP server, but the client absolutely will not be on that vlan.

    I don’t think that the fog server is running dhsmasq, unless it automatically installed when i install fog.
    ps -ef | grep dnsmasq
    The above only shows the command itself. I’m not an expert (obviously), but i think it isn’t running. If there is something else you’d like me to check, just let me know.

      @cklemm I’m only working from the perspective of what is in the pcap file you captured.

      Because we are dealing with broadcasts, and unicast messages, ideally we would like to see the fog server, dhcp server, and pxe booting computer on the same subnet so we can get an accurate picture of what is going wrong. We can get what we need captured in a round about way.

      FOG WILL work in the setup as you described.

      OK just to reconfirm, you did change the fog server IP address after FOG was installed? This is important since when FOS boots (custom linux that runs on the pxe booting computer), part of its network testing for dhcp is to try to communicate with the FOG server. FOS will report that it doesn’t have an IP address, but what is really happening is that it’s trying to ping the FOG server and its getting no response. So FOS assumes it doesn’t have a good network connection.

      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!

        @sebastian-roth said in Resgistration Issues:

        The best to go about this would be to capture the full traffic right at the client. You can either do this by configuring a monitoring port on the switch where you client is directly connected to. The other usually easier option is to grab an old network hub and connect that between your client and the network switch. Jack in another PC/notebook to that hub and you can capture all the network traffic being send forth and back from and to the client.

        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)

          @george1421 I did not change the IP after FOG was installed. Is there something i can check that would show which IP FOS is pointing at so i can be sure that is correct?

          @sebastian-roth Ok, i’m working on it. I’m finding it hard to get a working hub, but i’ll post here when i have it.

            So i still don’t have the packet info from the hub, but i restarted the computer while it was hooked into the hub, and just for kicks i decided to try to register the client. It worked.

            A month of restarting the client and as soon as i plug it into a hub of all things it works. Right now it is capturing the image (at least, i’m pretty sure that’s what it’s doing). Does that give you any information? it makes me think it is a network configuration issue. I’m still going to try to capture the packets, but i thought this was worth posting.

              @cklemm Nice one! Don’t bother about capturing the network packets.

              Read up on spanning tree and port fast settings. It’s either that or even possible EEE (ethernet energy saving stuff) or an Auto-negotiation issue.

              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)

                @sebastian-roth Just an update, i was able to get this to work even in another building. Apparently this was a problem specific to the random old switch i was using to test this stuff. Thanks so much Sebastian and George.
