Question

I am facing problem to create a session to a remote SFTP server by JSch:

The command i use to connect the sftp server through shell is:

I have implemented the solution , I added the following code before calling session.connect().

session.setSocketFactory(new SocketFactory() 
{
    InputStream in = null;
    OutputStream out = null;

    public InputStream getInputStream(Socket socket) throws IOException 
    {
        if (in == null)
            in = socket.getInputStream();
        return in;
    }

    public OutputStream getOutputStream(Socket socket) throws IOException 
    {
        if (out == null)
            out = socket.getOutputStream();
        return out;
    }

    public Socket createSocket(String host, int port) throws IOException, UnknownHostException 
    {
       // The IP Addresses are changed ....
       // using the original IP in my code
        byte[] remoteIpAddr = new byte[] { (byte) 11,(byte) 11, 11, 11 }; 
        byte[] localIpAddr = new byte[] { 55, 55, 55, 55 };

        InetAddress remoteIp = InetAddress.getByAddress(remoteIpAddr);
        InetAddress localIp = InetAddress.getByAddress(localIpAddr);

        logger.debug("remoteIp >>" + remoteIp.toString());
        logger.debug("localIp >>" + localIp.toString());
        Socket socket = new Socket(remoteIp, 22, localIp, 0);
        logger.debug("socket created >> " + socket.toString());
        return socket;
    }
});

And its creating the socket : checked the log file for >>

logger.debug("socket created >> " + socket.toString());

But now I am getting an exception :

Auth cancel

What may be the cause , The key which I have is a id_rsa.pub file, which starts with

ssh-rsa AXTYU....

and I have created the private key file from this file through keygen which I am using in my session.addIdentity() method, the format of the private key is :

-----BEGIN RSA PRIVATE KEY-----
KIOPU.....
-----END RSA PRIVATE KEY-----

Am i missing something , please suggest...
