UDPMulticastGroupListener

Little utility to listen on a UDP multicast group and print the data

Code Setup

The code has some initial defaults that I setup, defaults are in ()'s:

• MODE - Which mode are we in IPv4 or IPv6 (IPv6)
• INTERFACE - Which interface to use ie. eth0, en0, etc. (null) - All Interfaces
• LISTEN_PORT - Which port to listen on (35056)
• MULTICAST_GROUP - The IPv4 or IPv6 Multicast Group (FF02::1)
• LISTEN_ALL_INTERFACES - Listen address for all interfaces (::)

You can override the options via the following env variables:

• net.ip_mode - must be "IPv4" or "IPv6"..defaults to IPv6
• net.interface - defaults to All Interfaces
• net.listen_port - defaults to 35057

You'll most likely want to override the net.interface to match your system.
