How To Check Multicast

Carlwill · 2010-07-02 15:05:05

I have two machines connected to a generic Linksys switch and am running an application that requires multicasting be enabled on both clients on the switch. Is there a way I can test and or verify that both Arch Linux machines have multicast enabled on them?

[karol@black test]$ ifconfig

Is that what you mean?

So if I do an 'ifconfig' on a specific interface and see the MULTICAST line then it should be up and running, right?

I don't know of any other multicast, but then again I'm no guru wrt to networking so I may be wrong.

Is your app running OK?
