Same applications appear to work on 2.4 kernels. What seems to be happening is that the application binds to the lo interface instead of eth0 so that no IGMP queries are send out on the ethernet interface. I have a small application that tries to listen to address 233.4.5.9 and here is /proc/net/igmp with and without the app running: Withtout app running: Idx Device : Count Querier Group Users Timer Reporter 1 lo : 0 V2 010000E0 1 0:FFF779D7 0 2 eth0 : 3 V2 010000E0 1 0:400DA3C3 0 With app running: Idx Device : Count Querier Group Users Timer Reporter 1 lo : 0 V2 090504E9 1 1:00000C28 1 010000E0 1 0:FFF73910 0 2 eth0 : 3 V2 010000E0 1 0:400D62FC 0 Is there a known problem? Or should multicast applications be changed to run on 2.5 kernels?
