public static String runCommand(String hostname, String username, String password,String cmd){
        Connection conn = new Connection(hostname);
        Session sess = null;
        try
        {
            conn.connect();

            boolean isAuthenticated = conn.authenticateWithPassword(username, password);
            if (isAuthenticated == false){
                throw new IOException("Authentication failed.");}
            sess = conn.openSession();
            //sess.execCommand("uname -a && date && uptime && who");
            sess.execCommand(cmd);
            InputStream stdout =    sess.getStdout() ;
            BufferedReader br = new BufferedReader(new InputStreamReader(stdout));
            StringBuilder sb = new StringBuilder();
            while (true)
            {
                String line = br.readLine();
                if (line == null)
                    break;
                sb.append(line+"  ");
            }

            //  System.out.println("ExitCode: " + sess.getExitStatus());
            System.out.println(sb.toString());
            return sb.toString();
        }catch (IOException e){
            e.printStackTrace(System.err);
            return "0";
        }finally{

            sess.close();

            conn.close();
        }

       // return "1";
    }

例:runCommand("100.100.2.200","root","root","ls")
