    Hello,

    We’ve noticed an issue with a fresh Trunk installation (and upgrade after that) that the multicast session gets started on the wrong eth port.

    We’ve found an article on this, explaining that you can select a eth port in the storage nodes configuration but, apparently eth0 is selected there, but the multicast service outputs to eth1. This is a nic that is not connected.

    We are running fog on ESXi, with 2 nics attached to the VM

      @abos_systemax Yesterday I was wrong when saying that Tom has changed some interface detection code as this was not related to the bandwidth stuff in question.

      So I am just trying again: Moving this to bug reports as I remember @Tom-Elliott having changed the interface configuration/discovery code not long ago.

      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)

        There is also a multicast section in the settings area where you can specify your multicast interface, make sure that’s set to eth0

          all settings were set to eth0. As soon as we removed eth1, the multicast got onto the right eth port

            @abos_systemax If you’re not using eth1, I think you can disable it in Linux for the time being, but this is definitely a bug.

              What version of FOG are you running?

              I ask because, @Sebastian-Roth is correct that I changed ethernet discovery for multicast tasks.

              Ultimately, the new code takes the Storage Node’s IP/Hostname and tries to find the interface that’s using that IP Address. (I convert hostname to IP address in case it’s stored on the Node in FQDN/Hostname form.)

              How well it works, I don’t know as I can not test all potential scenarios.

              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!

                  @abos_systemax When the command starts, I know it’s showing on the wrong interface, but is it also showing the wrong IP address?

                      Hi Tom, sorry for me not replying. I was busy with different work in the meantime.
                      I am unable to recall the IPadress of the NIC, because the chosen NIC was connected to a VLAN that does not have a DHCP-server nor a static IP assigned. Also; as soon as we took the other NIC down, the problem resolved itself. I am willing to check what happens if I re-enable the second NIC, but am not able to do so in the upcoming week.

                        Should we mark this solved for now as taking the second NIC down fixed the issue?

                          As far as I am concerned: Yes, but the issue itself might not yet be fixed

                              I just updated to lasted Trunk version today and have the same problem

                              Multicast setting
                              alt text

                              Storage node (I have only 1 node)
                              alt text

                              And this is multicast log (wrong interface and IP address)

                                  @dvchuyen Please update and see if all is a little better. I found I missed a grep statement in looking for the interface and hopefully have a correction for this.

                                  Thanks for the info thus far.
