        @cammykool said in TFTP ARP Timeout:

        inet 10.1.80.1/8 brd 10.255.255.255

        What I do notice here is that this broadcast address seems to not match the netmask we see in the picture you posted earlier. Either it’s /16 (255.255.0.0) or /8 (255.0.0.0). While this shouldn’t cause the ARP timeout I am still wondering why you have this mixed up here.

        its set to static info

        IP 10.1.80.1
        DHCP: 10.1.0.1

        Really static or maybe DHCP?? FOG server should always be configured to have a static IP!!

        Did you re-run the installer after you ran the updateIP script as well?

        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)

            @cammykool Fix the subnet mask on your FOG server first!

                67 is set to 10.1.80.1 in DHCP and ubuntu has it set up manually for the same

                  @cammykool OK wait a minute. Why does the first picture have a subnet mask of 255.255.0.0 (/16) and the ubuntu server have 255.0.0.0 (/8)

                    Also lets confirm what you have exactly configured in your dhcp server. What do you have defined for dhcp option 66 and 67 respectively?

                        @cammykool You also need to change it in the network manager since you are using ubuntu.

                        Then from the fog server command prompt key in ip addr show and confirm that the subnet mask matches the rest of your network. If it doesn’t reboot the fog server and then confirm.

                              @cammykool Actually if you look after the IP address is /8 or 255.0.0.0. Then reboot the fog server since it may only load at boot time.

                              edit, maybe you could do sudo ifdown enp0s25 then sudo ifup enp0s25 to avoid the reboot time.

                                Understand that fixing the subnet mask may not address the pxe booting problem, but it will fix ARP resolution. The subnet mask controls where the broadcast address is. Two different subnet masks have their broadcast address in different locations so the two clients will have difficulty finding each other.

                                  @george1421 it looked to be /8 too before

                                  pxe is still getting 255.255.0.0 at boot

                                    @cammykool So you updated the network manager application and then either did the ifup/ifdown or reboot and its still set to /8?

                                    The pxe stuff is coming from your dhcp server not the fog server. Your client is still having a problem finding the fog server from your first picture.

                                      yes it is. Netowkr manager has always been correct.

                                          Ok I think I’m lost here (not surprised since I jumped in late). The subnet mask of /16 255.255.0.0 is coming from your windows dhcp server. That has to be the right subnet mask for your network. Why is the FOG server set to /8 255.0.0.0?

                                          What is the correct subnet mask for your computers? You can open a command windows on your dhcp server and key in ipconfig /all to confirm your subnet mask. The fog server needs to have the same subnetmask as your windows servers.
