ip maddress add 188.8.131.52 dev eth0
ip maddr show
does not show this maddress joined. Any idea? This is a redhat linux. multicast is enabled.
I have debian box connecting two interfaces eth0 and eth1. In the network of eth1 (if I plug there my computer) I can watch a stream using i.e. vlc on udp://@239.x.x.x:x there. I would like to have the same option in the network of eth0.
That only lists interfaces that are currently up. Are you connected through eth0 or wlan0 when you run that command?I'm not sure if it's the "right" way, but `ip maddress` shows all my interfaces, while `ip address` shows only those that are currently connected.edit: `ip link` is probably the right command to list all interfaces.
I have recently updated one of my systems from CentOs 6.4 to CentOS 6.5.
This systems is used as a RIPv2 routing server with quagga which is the termination point of some GRE tunnels.
While running CentOS 6.4 I see the multicast packages arriving at the eth0 and the GRE tunnel interface.
While running under CentOs 6.5 I can see the multicast packages arriving at the eth0 but not on the GRE tun
I'm trying to do some multicast big file copies over to remote clients on the other side of a satellite link. The idea is to minimize the amount of traffic going up to the satellite.
I tried using uftp without luck. The problem is that, even though we can reach clients via multicast from our central Hub, they aren't able to respond to a multicast address (it's not supported by the return link).
I'm trying to understand how Multicast actually works, and have read numerous articles and Wiki pages, and have gathered this:
A multicast address takes up state on the router of the membership, which is a scalability concern
There are commands to view the Multicast state on a Windows machine
IPv6 requires Multicast as broadcast is no longer an option.
