[Gumstix-users] UDP Mutlicast Almost Working

[chewygumstix <dan...@lm...>]

I'm running a system where Windows systems will be communicating back and
forth with a gumstix via UDP multicast and am having a problem.

I have a send test app and a receive test app that compile for linux and
windows. When I run both applications on the gumstix they can communicate
fine. Same goes if both on are Windows. I can also send udp packets from the
gumstix and receive them in Windows. However I can't receive packets on the
gumstix that were sent from Windows.

I consider myself a novice when it comes to linux, so I'm probably doing
something dumb.

To get multicast to work as I have it now I had to do the following:

iproute add 224.0.0.0/4 dev eth0

So I guess here are my questions:
Is there something I need to do to enable receiving external udp multicast
packets on the gumstix?
And is there a command in linux to view packets being received on the
gumstix?

Thanks
