    @george1421 - Current uptime was 1 day 14 hours. I have just now:

    • Cleared all tasks, rebooted and created a new multicast task - the log file still says “–interface dev”.
    • Cleared the tasks, changed the multicast interface to “eth0” (which doesn’t exist) and created a new multicast task - same result.
    • Cleared the tasks, rebooted and created a new multicast task - same result.

    The only things running on this server are FOG and dnsmasq. It is a VM under KVM and has 4GB RAM and a single processor. I have done a single in-place upgrade from 1.5.7 since my original install. I did have to recover the MySQL password (I was distracted and lost the new password before I could record it), but I recovered it without issue.

    I have also updated the fogservice.class.php and FOGSnapinReplicator.service files as per the Interface not ready, waiting for it to come up post.

      Good point. I just remembered that too.

      Please run the following command as root and post output here: /sbin/ip route
      The IP address configured for the storage node might play a role here too. Please post the IP set for the storage node 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)

          Here we’ve got it. You seem to have configured your network interface ens3 via DHCP - looks like it from the output. While our code should not fail to find the right interface I still wonder why you would configure a servers IP via DHCP!?

          Just configure the same IP but static in Linux network settings, restart your FOG server and it will most probably work!

            @Sebastian-Roth - I look after a network with over 600 servers at work. The ones that cause me problems are the ones with static IP addresses - generally because somebody makes a typo when they are configuring an interface. We also do a lot of migrations, mergers and other changes, so reserved addresses in DHCP make that much easier, as well as enforcing consistency and a basic level of self-documentation. DHCP also makes it easier to deploy in environments where the user does not have control of the network.

            I’m sorry for taking up your time, @george1421, and thank you both.

              @3mu I will be looking into fixing this issue! Though I can’t promise you when the next release will be out. Would you want me to post the fix here so you could manually add it?

                That would be great, thanks @Sebastian-Roth. I’m happy to test.

                  @3mu Sorry for the delay. I just had a play with this and I think it’s best to go for a simple fix: https://github.com/FOGProject/fogproject/commit/21460c1d8ba7dae1b2988b9287c188595ce01e9d

                    Thanks, @Sebastian-Roth. I’ll test as soon as I finish sorting out a few disasters - hopefully in the next day.

                      @Sebastian-Roth - Sorry for the delay - some other unrelated issues and then a pandemic to deal with! The fix works perfectly.
