              try
              {
  
                  Socket s = new Socket(args[0],Integer.parseInt(args[1]));
                  BufferedReader br=new BufferedReader(new InputStreamReader(System.in,"CP866"));
                  String str;
                  str=br.readLine();
                  str = str+"\n"+s.getInetAddress().getHostAddress()
                  +":"+s.getLocalPort();
                  PrintWriter pw = new PrintWriter(new OutputStreamWriter(s.getOutputStream()));
                  pw.println(str);
                  pw.flush();
                  while(true){
                      str=null;
                      if((str=br.readLine())==null)
                      break;
                      str = str+"\n"+s.getInetAddress().getHostAddress()
                      +":"+s.getLocalPort();
                      System.out.println(str);

                  pw.flush();
                  }
              }
              catch(Exception e)
              {System.out.println("init error: "+e);}
