[jboss-jira] [JBoss JIRA] Commented: (JGRP-515) UDP.java requires the multicast address in the multicastsocket constructor to fix crosstalk on certain operating systems

[ http://jira.jboss.com/jira/browse/JGRP-515?page=comments#action_12364865 ] Bela Ban commented on JGRP-515: ------------------------------- If I make the suggested change in mcreceive.c: /* construct a multicast address structure */ memset(&mc_addr, 0, sizeof(mc_addr)); mc_addr.sin_family = AF_INET; // mc_addr.sin_addr.s_addr = htonl(INADDR_ANY); mc_addr.sin_addr.s_addr = inet_addr(mc_addr_str); // <==== changed ! mc_addr.sin_port = htons(mc_port); , where I bind to the multicast address and port, then this works on Linux (Fedora 7), but fails on Windows: $ ./mcreceive.exe 228.8.8.8 7500 bind() failed: Cannot assign requested address (my routing table is below) I thought that bind() had to accept the address associated with a local network interface, so that a class D address is invalid.
