Multicast

Make sure multicast is enabled at kernel level.

To compile multicast support into the kernel, CONFIG_IP_MULTICAST must be present in the kernel configuration file.

Verify that the network interface you plan to use for multicast traffic has multicast enabled, and if not, turn it on.
Configure multicast routing: Configure Multicast Routing
If iptables runs on the system, allow multicast traffic for the interface that will handle multicast traffic: Configure iptables to allow Multicast
Test it. For more details see the Troubleshooting section.

netstat -g

displays multicast group membership information for IPv4 and IPv6. Optionally use -n to prevent DNS lookups (faster).
