Are there any multicast stream scanners?

Question

linux

Good afternoon.
Does anyone know a program that searches for multicast channels in a given range of addresses on the network, subscribing to each one in turn and compiling a list of those found. In the same place, not only the address is needed, but also the port, how to deal with it?

Answer 1

It is proposed to take scapy and send an IGMP-JOIN request to the network for each address. In parallel with this, in wireshark / tcpdump, see if anything has started to fall from the network.

Answer 2

I'm afraid of multicast in the network half directed. if it is not open in your direction ... then at least look around =)

Answer 3

tcpdump - write a specific multicast to a file, specify it as host, without specifying a port.
pcapreport -x from the tstools package extracts all streams from the dump and decomposes them into separate files.
As mentioned above, multicast should be available to you.

Answer 4

How about StreamXpert?
