Re: How to set interface for Multicast server ?
Jacob,
If I understand your question correctly, I think I ran into the same
problem a few weeks back---i.e. there is currently not a good way to bind
the iperf server to a multicast address on a specific network interface on
machines that have more than one interface.
...the way I got around it was to create a static route whenever I needed
to do it:
route add 224.0.67.67 dev eth1 (this is assuming that "eth1" is the
network device corresponding to the network interface whose hostname is
"node2")
...by default mcast routes will be associated with an interface the kernel
picks (usually the first to come up).
