what is the mechanism by which the message is being received? is this a message sent via akka remoting, or is this a TCP connection being accepted by akka IO, or a spray HTTP request, or ?

if it is a message that was sent via remoting, you can look at the Address of the sender() actor ref. sender().path.address will contain the address of the sender. see http://doc.akka.io/api/akka/2.3.7/index.html#akka.actor.Address

if it is a TCP connection accepted by akka IO, then the Connected message will contain the remote and local InetSocketAddress. see http://doc.akka.io/docs/akka/2.3.7/scala/io-tcp.html#Accepting_connections

Hello,

I'm wondering whether AKKA has some mechanism which can be used to filter out incoming message based on IP Address, e.g. if I don't want to process messages from some specific node, how should I do?

Thanks.
