I'd say it's probably a Linux multicast issue, and if you translate the 
Ruby code to C (which is pretty much line-for-line) you may be able to 
replicate it separately. In that case, the linux-net gurus will be able 
to help you.

0.0.0.0 is not a multicast address, and I'm not sure if this is a 
legitimate address to 'join'. Perhaps try binding to the actual 
multicast address that the server is sending to? However I'm not a 
linux-net guru.

Oh, and not that it affects code operation:  s/RECIEVE/RECEIVE/  :-)

Brian.
