Re: [beagleboard] Re: BBB MultiCast
Well . I know google too, and I know this link . Thx for the answer . My problem is that the beagle still receive the multicast packet (yes it ignore all multicast packet), which is a problem for me when you are in a network full of camera That love to send multicast packet ! I tried to disable multicast in the kernel, but it still receive multicast packet. Do you know a solution to prevent this ?

Re: [beagleboard] Re: BBB MultiCast
From tcpdump man page:
*-p**--no-promiscuous-mode**Don't* put the interface into promiscuous mode.
Note that the interface might be in promiscuous mode for some other reason;
hence, `-p' cannot be used as an abbreviation for `ether host
{local-hw-addr} or ether broadcast'.

What does the -p do?

I also tried to ping 224.0.0.1 from an another device .
And with the command tcpdump I can see that I'm receiving multicast

Why ? I really don't know what to do about it, My idea is to deactivate
