Hello,
There is no /opt/fog/service/common/etc/config.php file, I supposed you meant /opt/fog/service/etc/config.php 🙂
service FOGMulticastManager status does not work, only start|stop|restart, start fail at first, but stop work, then start work, and still no multicast working 😞
I forgot something else in the “What I have already done list” : ip igmp on all my HP switches, and no router between FOG server and any of my clients.
update after some more tests: ps aux | grep udp returns something when I run “gunzip -c “/images/anyimagename” | /usr/local/sbin/udp-sender --min-receivers 2 --portbase 9000 --interface myInterface --half-duplex” manually from command line then connect with debug mode 2 clients, but still nothing when I start a new multicast task from fog management webpage.
