Hi! I'm trying do send a UDP packet to a ipv6 host but without success:
Exception in thread "main" java.io.IOException: Address family not
supported by protocol at gnu.java.nio.VMChannel.send6(Native Method)
at gnu.java.nio.VMChannel.send(VMChannel.java:310) at
gnu.java.net.PlainDatagramSocketImpl.send(PlainDatagramSocketImpl.java:261)
at java.net.DatagramSocket.send(DatagramSocket.java:659) at
teste.main(teste.java:28) When I try to send to a ipv4 it seems all
ok... In other hand, when I try receive a packet (using a java app in
jamvm), my app freezes in "socket.receive".... .... [Linking class
gnu/java/nio/charset/ByteEncodeLoopHelper] [Loaded
gnu/java/nio/charset/ISO_8859_1$Encoder$1 from
/usr/share/classpath/glibj.zip] [Linking class
gnu/java/nio/charset/ISO_8859_1$Encoder$1] heeeyyyyyyyyy <----------- a
println before "socket.receive" [Loaded java/net/DatagramPacket from
/usr/share/classpath/glibj.zip] [Linking class java/net/DatagramPacket]
[Loaded java/nio/VMDirectByteBuffer from /usr/share/classpath/glibj.zip]
[Linking class java/nio/VMDirectByteBuffer] (and stays here...) after
that socket.receive have another println but don't appears the message.
When I create the DatagramSocket I think it is normal do the bind but
looking to tcpdump (and having another app in another pc sending the
packets), says destination unreachable, a common message when the
destination port is not binded. I'm compiling in windows using java 1.6
(jamvm uses 1.5)... can be one of the problems? I'm using openWRT
