Reusing IoSession with SshClient (reversessh)

[Vikram Darsi <vi...@overturenetworks.com>]

Hi

We have a Netconf protocol implementation on top of Apache MINA and Apache SSHD, and currently working on new feature "reverse SSH"


1. Apache MINA's NioSocketAcceptor is used to accept incoming connections and a StreamIOhandler is set to it.

2. So, when a connection is accepted, we have a IoSession, InputStream and OutputStream with us

3.  As per the concept of reverseSSH, all further request's should use the same channel.

Here comes the need to attach the IoSession to Apache SSHD's SshClient

The following is the code snippet written for achieving this in Open Daylight


sshClient.setIoServiceFactoryFactory(new IoServiceFactoryFactory() {
            @Override
            public IoServiceFactory create(final FactoryManager manager) {
                return new MinaServiceFactory(manager) {
                    @Override
                    public IoConnector createConnector(final IoHandler handler) {
                        try {
                            return new Nio2Connector(manager, handler, AsynchronousChannelGroup.withThreadPool(MoreExecutors.sameThreadExecutor())) {
                                @Override
                                public IoConnectFuture connect(final SocketAddress address) {
                                    DefaultIoConnectFuture defaultIoConnectFuture = new DefaultIoConnectFuture(null);
                                    defaultIoConnectFuture.setSession(ioSession);
                                    return defaultIoConnectFuture;
                                }
                            };
                        } catch (IOException e) {
                            // FIXME
                            e.printStackTrace();
                        }
                        return null;
                    }
                };
            }
        });


sshClient.start();

Are these steps correct? If not, can you please let us know the correct steps.

4. For further communication can we use this SshClient API to talk to the devices in usual manner?



Thanks
Vikram
