#it #networking gurus!
I have a number of real-time systems that #multicast data. I want to forward that mcast data from one machine to another on the same physical network but a different mcast address (I guess...?)
It looks like #ncat, #socat and maybe even #ssh could do this but I can't figure out how to do it with multicast specifically
@T_X @troglobit There are three multicasts, two of which are on the same multicast addr. I assume those are somehow being routed to not interfere with each other
The two non-overlapping ones I can already receive on machine A. I can get the third cast on machine B. A and B can reach each other
I'd like to forward B to A, ideally still as multicast but on another address (to simplify my code). Forwarding A to B would be better, just because I have more control over B (i.e. root, etc)
@T_X @troglobit Oh, I should probably also note that most of these machines have multiple NICs. There's some complicated subnet scheme in use that I don't understand but doesn't seem to affect the multicasts (i.e. apparently I can get the casts on any of the NICs)
It would probably also help a lot if I understood multicast better...
@davidr @troglobit I'm also still a bit confused myself how your setup looks like :D. A diagram would be nice with the involved hosts, their network cards, how these are connected and the packets are supposedly travel.
I think the two green boxes with in example 1 are actually a great point to start with, just try them out :-). One is the multicast sender and the other the multicast receiver side.
