If my guess is right and you mean ActorSystem in all places where you say “Actor” then no, neither is possible. Please have a look at the docs which explain that Akka remoting is only peer-to-peer. > > Or, Does actor receive any message where the sender is not an actor?

No, only actors can send messages to actors. The reason is simply that without a reply you will never know whether the message arrived, so if you care about the message you will have to be able to receive a reply at the sending actor. > > > The Second Question: > Does actor shutdown context.system.shutdown() close its port? Yes, but if you are tempted to repeatedly create and destroy ActorSystems then please take my advice to just not do not ;-) You should keep the ActorSystems running, they are heavy objects and take a long time to start up and shut down. You can configure the port number to zero in order to have them pick a free TCP port automatically, though. Only your “server” system needs a known port which the workers talk to.
