Wow, thank you so much, that was incredibly helpful. I was in fact binding to INADDR_ANY. For the record, when creating the ACE_SOCK_Dgram_Mcast object (essentially an object wrapper for a socket), I need to pass in the OPT_BINDADDR_YES option (which causes the socket to bind() to a specific address, as opposed to INADDR_ANY). Thanks again to David and everyone else for all the help! -Matt -- To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
