Package eu.tneitzel.rmg.networking

Class DGCClientSocketFactory

java.lang.Object

java.rmi.server.RMISocketFactory

eu.tneitzel.rmg.networking.DGCClientSocketFactory

All Implemented Interfaces:

RMIClientSocketFactory, RMIServerSocketFactory

public class DGCClientSocketFactory
extends RMISocketFactory

The DGCClientSocket factory is used when the --ssrf-response option was specified on the command line. In this case, the user may supplies an SSRF response that contains a remote object reference. These references create outbound DGC connections upon deserialization. To prevent these outbound connections, we use a dummy socket factory. This factory returns sockets that discard all incoming data and return an malformed DGC response when being read. Since no outgoing data is expected when using --ssrf-response, this socket factory is set to the default RMI socket factory if the --ssrf-response option is used.
