      Description

      Hi, multicast deployment doesn’t work on my server, as clients hangs at the blue screen.
      I 've read carefully the wiki and performed the 1 client test with commands udp-receiver and sender. This test failed :
      On server side, i see a new connection with the correct ip, on client side, the clients seems to be ready, but whent i hit a key on the client, it just prompt " sending go signal" and nothing appears …
      The multicas.log shows the task, but when the transfer should begin, it shows " TimeOut"

      I’ve checked the network switches ( IGMP and SPT is enabled ) , on the server iptables is enable but without rules, ping 224.0.0.1 is ok, …
      If anyone has an idea, I would be very grateful .

      Thanks for your amazing work on FOG

        Is the fog server and the target computers on the same IP subnet?

        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!

          As I’m not a specialist, yes they are : fogserver is 172.16.1.111 and the dhcp range is
          172.16.13.0 to 172.16.16.255. the dhcp server is a windows 2012 server

            @Flavalf What is your subnet mask for both the fog server and the dhcp range. The reason why I ask is that there is a potential for the FOG server to be on another subnet (vlan) than your dhcp clients.

            FOG server
            172.16.1.111

            dhcp range
            172.16.13.0 to 172.16.16.255

            If your subnet mask is something like 255.255.0.0 then what you’ve posted is correct. What I’m trying to understand is if there is a router between the clients and the FOG server. FOG-casting on the same subnet shouldn’t be a problem between subnets then you might have an issue.

                  @Flavalf I just chatted with one of the devs and he recommended that you test the 1.4.1RC0 inits. There was a fix put into those inits to address a multicasting issue. Your issue sounds similar.

                  https://fogproject.org/inits/init.xz
https://fogproject.org/inits/init_32.xz

                  Download those and replace the ones on the fog server in /var/www/html/fog/service/ipxe directory.

                    I’ve replaced the files in /var/www/html/fog/service/ipxe ( no need to reboot I guess ? )
                    I’ve rebooted the client and … get the same issue 😥
                    I don’t know if it’s normal or not but I can’ t ping 224.0.0.1 from the client :

                      Hi, feedback on my issue : it was ( as usual ) a network cause.
                      IGMP was enable on switches but no switch was querier and no multicast group has been set.

                      Now , the 1 client test is ok, I can go further and make it works !
                      Thanks for support.

                        @Flavalf Thanks for keeping us posted on this. This is very helpful information for others having issues with multicast!

                        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 You’re welcome …
                          For info, my switches are HP Procurve and I used these links to configure them !

                          https://community.spiceworks.com/how_to/26481-enable-igmp-on-hp-procurve

                          Now, Multicast is working properly : I imaged 3 clients at 1.4 Gb/min, next I will try 10 or more !
