This is a patch to add the multicast maxwait time to the WebUI instead of having to edit config.php each time you want to change the setting. Good for someone who changes this setting a lot. There are two files in the attached tar.gz. 1.) MulticastTask.class.php. Place this into /opt/fog/service/common/lib then restart the multicast manager with: sudo /etc/init.d/FOGMulticastManager restart or reboot your fog server. 2.) maxwait.sql import this into your database with: sudo mysql -u root -p fog < maxwait.sql . If anyone wants to know the lines that were changed in MulticastTask.class.php are 64-67, 83, 97, 108, 111, 133-136.
