True, the switch know nothing about ip multicast, I just mencioned that to say the kind of network I have.
Using multicast MAC address too? I'll find that out. The thing is that all other computer on that network respond to the multicast, except for the ones with suse 9.2.
Again, use a network monitor program, such as ethereal, to see what's actually happening. Otherwise, we're guessing.
Hello, once again. I've conducted tests as such that you told, but the is that the packets arrive at my computer, if I activate suse firewall and I watch on "/var/log/messages" I can see the packets arriving at my computer. My computer just don't respond to them.~ I used the Ethereal and again I get the same results, the packets arrive at my computer, it just don't respond to them. Don't know what else to do.

Don't know what else to do.
man ifconfig [-]allmulti Enable or disable all-multicast mode. If selected, all multicast packets on the network will be received by the interface.
Well, Tried that already, still even so, there's no reply to multicast commands. I issue: >ifconfig eth0 allmulti Then with : >ifconfig I already has ALLMULTI flag active, but still with ping 224.0.0.1 it simply wont respond. Does anyone with kernel 2.6.8-24.10 or above successfully had multicast running? Don't know if this is a kernel issue or not? (perhaps this is stupid, but I'm desperate).

Are you sure a multicast ping should respond? The machine may be getting the ping and just not answering..... I have gotten mutlicast video to work (VideoLanClient). Don't know that I ever tried a ping. B-) On Wednesday 19 January 2005 10:25 am, Hugo Veiga wrote:

It essential that you use multicast? Could you possibly use subnet broadcast (10.0.255.255) ?
