[ http://jira.jboss.com/jira/browse/JGRP-639?page=all ] Bela Ban updated JGRP-639: -------------------------- Description: This doesn't work on Windows, so try-catch it and create new MulticastSocket with a wildcard bind address. (2.4.2 is the equivalent of 2.4.1. SP5) - Bela was:This doesn't work on Windows, so try-catch it and create new MulticastSocket with a wildcard bind address. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[ http://jira.jboss.com/jira/browse/JGRP-639?page=comments#action_12393339 ] Bela Ban commented on JGRP-639: ------------------------------- I tried to bind the MulticastSocket to the multicast address and port, but it failed on Linux & MacOs with an exception "cannot assign requested address". This was done with mcreceive.c, attached to http://jira.jboss.com/jira/browse/JGRP-515. /* 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_port = htons(mc_port); was changed to /* 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(mc_addr_str); // <=== mc_addr.sin_port = htons(mc_port); This does not work on Windows, MacOs and Linux (2.6.22) ! -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

Need to find out why UDP.createSockets() fails if I change it to look like the code below. public class bla { public static void main(String[] args) throws Throwable { MulticastSocket sock; SocketAddress saddr=new InetSocketAddress("228.8.8.8", 5000); sock=new MulticastSocket(saddr); sock.joinGroup(InetAddress.getByName("228.8.8.8")); } } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[ http://jira.jboss.com/jira/browse/JGRP-639?page=comments#action_12393551 ] Bela Ban commented on JGRP-639: ------------------------------- OK, found the reason: when -Djava.net.preferIPv4Stack=true, mcast_addr of 228.8.8.8 is correct. However, when we use IPv6, then the mcast_addr of 228.8.8.8 cannot be used; and we need to define a different, IPv6 compatible multicast address ! -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[ http://jira.jboss.com/jira/browse/JGRP-639?page=comments#action_12396717 ] Bela Ban commented on JGRP-639: ------------------------------- The solution is to use the multicast address to create the MulticastSocket: mcast_sock=new MulticastSocket(new InetSocketAddress(mcast_addr, mcast_port)). If this throws an exception, we log it as WARN and retry with a null mcast_addr (this should usually work).
