java Android ganymed ssh2

1 年，4 月 Questions & Answers 432

我尝试打开到服务器的ssh连接。为此，我使用Ganymed SSH2修订版262

我创建了一个SSHJava类

public class SSH {

public String connection() {

    String Hostname = "XX.XX.XX.XX";
    String Login = "XXXXX";
    String PWD = "*******";
    String result = "";

    try {
        Connection connection = new Connection(Hostname);
        connection.connect();

        boolean isAuthenticated = connection.authenticateWithPassword(Login, PWD);

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

        Session session = connection.openSession();

        session.execCommand("uname -a");


        InputStream stream = new StreamGobbler(session.getStdout());
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(stream));

        while (true)
        {
            String line = bufferedReader.readLine();
            if (line == null)
                break;
            result = line;
        }


        session.close();

        connection.close();

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

    return result;
}}

我试着通过按下按钮来连接我的活动

public void sshConnect(View view) {

    SSH ssh = new SSH();
    SSHResult = ssh.connection();

}

但是我收到了一个错误
