    @Sunks We are more than happy to help you with whatever issue you have. But please open your own topic so we don’t get things mixed up here. As well I have to add that we hear things like “i have the same issue” often and most of the times it turns out to be a different problem! So please describe in detail your setup (OS version, FOG version, network setup, log files, …) and we surely will be able to give you a hand with this.

    @Miguel-Palacios Does restarting the service help for you? service FOGMulticastManager restart You should see newer messages in the logs…

    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)

        @Miguel-Palacios Is there some extra information in the Apache error log?

        In the mean time, updating to the latest and checking again might be useful.

                Do you actually see the new version number (7659) in the blue cloud on the web interface after upgrading to the latest?

                Please run:

                ls -al /opt/fog/service/FOGMulticastManager/FOGMulticastManager
                ls -al /var/www/fog/lib/service/fogservice.class.php
                ls -al /var/www/fog/lib/service/multicastmanager.class.php
                grep getBanner /var/www/fog/lib/service/fogservice.class.php
                

                Possibly the www paths might be /var/www/html/fog/lib/...

                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)

                      @Miguel-Palacios do me a favor and run

                      mv /var/www/fog{,_back}
                      ln -s /var/www/html/fog /var/www/fog
                      

                      Then rerun the installer please. Hopefully this will help.

                                    I solved this question in my case, perhaps it may help someone.

                                    • FOG 1.3-RC1 on CentOS 7.0.
                                    • Unicast deploy working.
                                    • Even multicast was working.

                                    After a system reboot, MulticastManager didn’t start again:

                                    Sep 4 06:01:28 clonacion FOGMulticastManager: PHP Fatal error: Call to undefined method MulticastManager::getBanner() in /opt/fog/service/FOGMulticastManager/FOGMulticastManager on line 13

                                    It didn’t matter if I added a multicast task: udp-sender process didn’t start because service didn’t start before (you’ll see only one FOGMulticastManager in process list --ps–, it’s the parent which forks periodically one child process (but this one will die at GetBanned method invocation).

                                    If I commented GetBanner() invocation out at /opt/fog/service/FOGMulticastManager/FOGMulticastManager, then it failed at next method call to object MulticastManager.

                                    I found TWO “MulticastManager” class, one of them extends FOGBase (at lib/fog directory) and the other one extends FOGService (at lib/service directory). Only the last one has defined methods like GetBanner(), etc. By any reason, it uses in some cases wrongly the first one (even when it used the second one after installation because it worked before).

                                    So, I renamed MulticastManager class that extends FOGService to MulticastManagerService, and I changed the code to use that. After that, service FOGMulticastService starts with no problems, it works. I did the same thing with rest of services: FOGScheduler,…

                                    I resume (for service MulticastManager: repeat it with other services in /opt/fog/services directory):

                                    1. Edit /opt/fog/service/FOGMulticastManager/FogMulticastManager file: modify line 8 from $ServiceClass = FOGCore::getClass(‘MulticastManage’); to $ServiceClass = FOGCore::getClass(‘MulticastManagerService’);

                                    2. Rename file /var/www/html/fog/lib/service/multicastmanager.class.php to /var/www/html/fog/lib/service/multicastmanagerservice.class.php (/var/www/html/fog is the path to fog web service)

                                    3. Edit /var/www/html/fog/lib/service/multicastmanagerservice.class.php and modify the name of this class (line 2) from “class MulticastManager extends FOGService” to “class MulticastManagerService extends FOGService”

                                        @habu there is only one multicast manager class. That is the one supposed to be in lib/service

                                        The one in lib/fog should read multicast sessions, multicast sessions manager, multicast sessions association, and multicast sessions association manager. Of course without the spaces.

                                          I wouldn’t advise trying to modify RC1’s code base. I would advise updating to the latest RC.
