交叉编译好了push到系统里面执行就可以看到效果

class Servicer implements Runnable {
 Socket s;
 public Servicer(Socket s) {
  this.s = s;
 }
 public void run() {
  try {
   InputStream ips = s.getInputStream();
   OutputStream ops = s.getOutputStream();
   BufferedReader br = new BufferedReader(new InputStreamReader(ips));
   DataOutputStream dos = new DataOutputStream(ops);
   while (true) {

抽空继续改进

1) 中文乱码了貌似

2)有的命令执行时貌似有bug?

3)增加文件上传下载功能
