It supports IPv4 and IPv6 any-source multicast and source-specific multicast. In standard mode it will multicast the standard-input verbatim. In listening mode it recieves the content and displays it on the standard output. .PP When given the optional source-address, mnc will attempt to use source-specific multicast. You may also specify this address in standard mode and mnc will use this source-address for outgoing packets. .PP .SH OPTIONS .IP \-l Listen for multicast packets. Default is to send. .IP \-i\ "interface" When listening for multicast packets, use the specified interface. .IP \-p\ "port" Specify a UDP port to use for sending or receiving packets. Default is to use port 1234. .SH "SEE ALSO" .BR nc (1) .PP .SH EXAMPLES To send IPv4 packets to an ASM group-id: .PP .RS mnc 233.1.2.3 .RE .PP To receive IPv4 ASM packets from the same group-id, using eth0 as the listening interface: .PP .RS mnc -l -i eth0 233.1.2.3 .RE .PP To receive IPv4 packets from an SSM group-id, using eth1 as the listening interface and 193.1.219.90 as the permitted source: .PP .RS mnc -l -i eth1 232.0.0.1 193.1.219.90 .RE .PP To receive IPv6 packets from an SSM group-id, using eth1 as the listening interface and 2001:770:18:2::90 as the permitted source: .PP .RS mnc -l -i eth1 ff31::12 2001:770:18:2::90 .RE .PP .SH CREDITS mnc is by Colm MacCárthaigh and is available from: .PP http://people.apache.org/~colm/mnc/ .PP Additional multicast development and support provided by John Lyons and Eoin Kenny
