      Je suis sur la version 1.5.9 de FOG. Une fois que j’ai sollicité un inventaire, il fait une recherche DHCP à travers udhcpc et ne trouve aucune IP. Pourtant notre Dhcp possède des IP de libre, et 66, et 67 sont bien paramétrés en UEFI.
      Le message exact est: udhcpc: sending discover(3 fois de suite, puis échec).
      Either DHCP failed or we were unable to access http://IP/fog//index.php.
      Normal il ne récupère pas d’IP. Pourquoi?
      D’autant plus que si je teste avec une VM sous Workstation, il trouve une adresse, et l’inventaire se poursuit normalement jusqu’au bout.
      Quelqu’un peut-il m’éclairer?
      Merci pour votre aide.

        @fogcc Make sure you update to the latest FOS Linux kernel by going to FOG Web ui -> FOG Configuration -> Kernel update. You want 5.15.x (latest version) for both x64 and x32 platforms.

        The boot order is pxe -> ipxe (FOG Menu) -> bzImage (FOS Linux kernel). Each step has their own network drivers.

        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!

          Hi,
          I get the same problem.

          • Get a DHCP address for loading EFI file
          • Get a DHCP address for Ipxe
          • Failing on the next step with the following error :
            udhcpc: sending discover 3x3 times
            Either DHCP failed or we were unable to access http://…

          Spanning-tree doesn’t seem to be the problem as connect the server and the client on a clean switch with ports configured as “portfast”. But i may be wrong somewhere.
          According to my tcpdump on the server, i never receive any dhcp request.
          So maybe this “mini-os” doesn’t have drivers for my DELL 3310
          I did try many “.efi” files, but none has worked. so maybe the .efi is not the problem.

          Would you mind explaining to me which file Fog is trying to load at this point ?
          So I could try to debug

          Thanks

            @tallier What you describe usually happens because of spanning tree being active on the network switch. Talk to your network guys and ask if they can configure spanning tree to use the faster RSTP (Rapid Spanning Tree Protocol).

            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
