I'm new to akka and wanted to connect two PC using akka remotely just to run some code in both as (2 actors). I had tried the example in akka doc. But what I really do is to add the 2 IP addresses into config file I always get this error?

First machine give me this error:

[info] [ERROR] [11/20/2018 13:58:48.833]
[ClusterSystem-akka.remote.default-remote-dispatcher-6]

(akka.remote.artery.OutboundHandshake$HandshakeTimeoutException:
Handshake with [akka://ClusterSystem@192.168.1.2:2552] did not

And second machine:

Exception in thread "main"
akka.remote.RemoteTransportException: Failed to bind TCP to
[192.168.1.3:2552] due to: Bind failed because of
java.net.BindException: Cannot assign requested address: bind

Config file content :

akka {

  actor {

    provider = cluster

  }

  remote {

    artery {

      enabled = on

      transport = tcp

      canonical.hostname = "192.168.1.3"

      canonical.port = 0

    }

  }

  cluster {

    seed-nodes = [

      "akka://ClusterSystem@192.168.1.3:2552",

      "akka://ClusterSystem@192.168.1.2:2552"]



    # auto downing is NOT safe for production deployments.

    auto-down-unreachable-after = 120s

  }

}



# Enable metrics extension in akka-cluster-metrics.

akka.extensions=["akka.cluster.metrics.ClusterMetricsExtension"]



# Sigar native library extract location during tests.

# Note: use per-jvm-instance folder when running multiple jvm on one host.

akka.cluster.metrics.native-library-extract-folder=${user.dir}/target/native

First of all, you don't need to add cluster configuration for AKKA remoting. Both the PCs or nodes should be enabled remoting with a concrete port instead of "0" that way you know which port to connect.

Have below configurations

PC1

akka {

  actor {

    provider = remote

  }

  remote {

    artery {

      enabled = on

      transport = tcp

      canonical.hostname = "192.168.1.3"

      canonical.port = 19000

    }

  }

} 

PC2

akka {

  actor {

    provider = remote

  }

  remote {

    artery {

      enabled = on

      transport = tcp

      canonical.hostname = "192.168.1.4"

      canonical.port = 18000

    }

  }

} 

Use below actor path to connect any actor in remote from PC1 to PC2

akka://<PC2-ActorSystem>@192.168.1.4:18000/user/<actor deployed in PC2>

Use below actor path to connect from PC2 to PC1

akka://<PC2-ActorSystem>@192.168.1.3:19000/user/<actor deployed in PC1>

Port numbers and IP address are samples.
