Multicast's roles in FOG
Multicasting in FOG uses UDPcast to send a single image to multiple computers using only slightly more bandwidth than sending the image to a single computer or unicast. Multicasting will be slightly slower than a single unicast task.
Testing Multicast
udp-sender http://linux.die.net/man/1/udp-sender
Inside the FOG DB, there are two multicast association tables. You can delete all the rows in those tables, re-install FOG, and try again.
mysql use fog DELETE FROM `multicastSessions` WHERE 1; DELETE FROM `multicastSessionsAssoc` WHERE 1; DELETE FROM `tasks` WHERE `taskTypeID` = 8; quit
Check the status of FOGMulticastManager and restart:
Fedora:
systemctl status FOGMulticastManager systemctl restart FOGMulticastManager
Ubuntu:
sudo service FOGMulticastManager status sudo service FOGMulticastManager restart
