To intercept when an inbound remote client has been closed you listen to ``RemoteServerClientClosed``
which holds the transport used (RemoteTransport) and optionally the address of the remote client that was closed (Option<Address>).
Remote Security
^^^^^^^^^^^^^^^
Akka provides a couple of ways to enhance security between remote nodes (client/server):
* Untrusted Mode
* Security Cookie Handshake
Untrusted Mode
--------------
You can enable untrusted mode for preventing system messages to be send by clients, e.g. messages like.
This will prevent the client to send these messages to the server:
* ``Create``
* ``Recreate``
* ``Suspend``
* ``Resume``
* ``Terminate``
* ``Supervise``
* ``ChildTerminated``
* ``Link``
* ``Unlink``
Here is how to turn it on in the config::
akka {
actor {
remote {
untrusted-mode = on
}
}
}
Secure Cookie Handshake
-----------------------
Akka remoting also allows you to specify a secure cookie that will be exchanged and ensured to be identical
in the connection handshake between the client and the server. If they are not identical then the client
will be refused to connect to the server.
The secure cookie can be any kind of string. But the recommended approach is to generate a cryptographically
secure cookie using this script ``$AKKA_HOME/scripts/generate_config_with_secure_cookie.sh`` or from code
using the ``akka.util.Crypt.generateSecureCookie()`` utility method.
You have to ensure that both the connecting client and the server have the same secure cookie as well
as the ``require-cookie`` option turned on.
Here is an example config::
akka {
actor {
remote {
netty {
secure-cookie = "090A030E0F0A05010900000A0C0E0C0B03050D05"
require-cookie = on
}
}
}
}
