    @foggymind Another note, I seem to be able to rename systems so communication with the fog client seems to be working.

      @george1421 I ran tcpdump on the fog server and got the following results.

        @foggymind What was your capture filter on the FOG sever? Was it according to the tutorial? https://forums.fogproject.org/topic/9673/when-dhcp-pxe-booting-process-goes-bad-and-you-have-no-clue

        From the screen shot it looks strange in that there was a discover, then 3 offers from the dhcp server and then after 4 seconds the client sends the request. What is the target computer playing hard to get?

        I would expect to see after that ACK, a query from the target computer to the FOG server asking for the file on udp port 69.

        Make sure you have the proper capture filter. Once you have a good pcap upload it to a file share site and post the link here or IM me the link. I need to look into each packet to find out what is going wrong. From the picture it should be working.

        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!

          I am wondering why we see three offers all coming from the very same IP. Is this the way Windows DHCP servers do this when they are in a sync pool?

          @foggymind Would be helpful if you could save and upload a PCAP file from Wireshark so we can have a deeper look as well to be able to help. If you don’t want to post this to the public then send George and/or me a private message in the forum.

          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)

          Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

            Thanks for the quick reply!

            From the screen shot it looks strange in that there was a discover, then 3 offers from the dhcp server and then after 4 seconds the client sends the request. What is the target computer playing hard to get? – not sure!

            Yes, I followed that tutorial, is there something else I need to do with the filters or just type in the command?
