Ganymed-如何执行需要密码的ssh / scp

Question

I use Ganymed , which is a library that implements the SSH-2 protocol, and I want it to connect to other sever and copy to other sever files.

The problem is that the ssh and scp commands requires a password (I cant do it with keys) and as I do it - it doesnt work.

Here is an example:

public static void main(String[] args)
{
    String username = "sabre";
    String host = "beta";
    String password = "xxxxxxxx";

    try
    {
        Connection conn = new Connection(host);
        conn.connect();
        boolean isAuthenticated = conn.authenticateWithPassword(username, password);

        if (!isAuthenticated)
            throw new IOException("Authentication failed.");

        Session sess = conn.openSession();

        sess.requestPTY("bash");
        sess.startShell();

        OutputStreamWriter writer = new new  OutputStreamWriter(sess.getStdin(), "utf-8");
        writer.write("ssh nir@192.168.1.123 \n");
        writer.flush();
        writer.write("password\n");
        writer.flush();
        writer.close();

        sess.waitForCondition(ChannelCondition.CLOSED | ChannelCondition.EOF | ChannelCondition.EXIT_STATUS, 10000);

        sess.close();
        conn.close();

    } catch (Exception e)
    {
        e.printStackTrace(System.err);
        System.exit(2);
    }
}

When I debug this I see that the server return that the access is denied.

I've never used Ganymed but just by looking at the code I suspect that you send password too early. You probably need to handle what server responds to you. In other words server receives not what you think it receives.
