#send_registry_list(opts = {}) ⇒ Array, NilClass

Sends a Registry list call to the RMI endpoint. Simulates a call to the Java java/rmi/registry/RegistryImpl_Stub#list() method

Parameters:

  • opts (Hash) (defaults to: {})

Options Hash (opts):

  • :sock (Rex::Socket::Tcp)

Returns:

  • (Array, NilClass)

    The set of names if success, nil otherwise

Raises:

#send_registry_lookup(opts = {}) ⇒ Hash, NilClass

Sends a Registry lookup call to the RMI endpoint. Simulates a call to the Java java/rmi/registry/RegistryImpl_Stub#lookup() method.

Parameters:

Options Hash (opts):

  • :sock (Rex::Socket::Tcp)

Returns:

  • (Hash, NilClass)

    The remote reference information if success, nil otherwise
