Solaris 8 seems to behave consistent with the patch I posted. Most of the RFC's I've looked at don't seem to have much to say about how multicasting works at the socket level. Is there an RFC or specification that spells this out, or is this one of those situations where things are somewhat open to interpretation? Thanks, Jeff
