The code does work in Linux. However, you need to look at the JDK source, not the Linux kernel source. In this file: http://hg.openjdk.java.net/jdk7/jdk7/jdk/file/9b8c96f96a0f/src/solaris/native/java/net/PlainDatagramSocketImpl.c in the mcast_join_leave() function, there are two code paths: (1) Linux, (2) Solaris. It looks like on Solaris, they support IPv4-mapped multicast addresses for IPV6, and things work when they create an IPv6 socket, and then put an IPv4-mapped multicast address in it. For Linux, they have specific code paths in that function which seem to force creating an IPv4 socket. -- Craig _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[email protected]"
