Has anyone tried Alvin Alexanders remote example on an ipv6 only (not mixed
ipv4/v6) machine say with akka 2.3.12 and scala 2.11.6 with java 7.
When i try this running both the local (client) and the remote (server
actor) i get this crazy at the local client and no success messages.

Meanwhile the server (remote side) seems to run fine although with a
similar message about deadletters delivery failed ---

I have no issues with the remote example on a very similar but ipv4 setup.
The client side akka configuration has hard-coded correct ipv6 address
(matches the /etc/hosts on the machine and exactly what scala repl says is
the getHostAddress())
# akka 2.1
akka {
loglevel = "DEBUG"
actor {
provider = "akka.remote.RemoteActorRefProvider"
}
remote {
transport = "akka.remote.netty.NettyRemoteTransport"
//log-sent-messages = on
//log-received-messages = on
netty {
tcp {
hostname = "2001:1b70:82a7:1099:10:61:140:130"
port = 0
}
}
}
}
----
# scala
Welcome to Scala version 2.11.6 (Java HotSpot(TM) 64-Bit Server VM, Java
1.7.0_85).
Type in expressions to have them evaluated.
Type :help for more information.
scala> java.net.InetAddress.getLocalHost.getHostAddress()
res0: String = 2001:1b70:82a7:1099:10:61:140:130
-----
for completeness the server side akka config
akka {
loglevel = "DEBUG"
actor {
provider = "akka.remote.RemoteActorRefProvider"
}
remote {
transport = "akka.remote.netty.NettyRemoteTransport"
//log-sent-messages = on
//log-received-messages = on
netty {
tcp {
hostname = "2001:1b70:82a7:1099:10:61:140:130"
port = 5150
}
}
}
}

Elsewhere on the web there are rumors that akka and ipv6 may work according
to some mailings.
But i've not been able to get it to work nor find any substantiated
information.
Also any information on the 2.4 version of akka with ipv6 is appreciated.
cheers
