winsock connecting two pc

[cppgangster]

hi, I am trying to establish a connection between two laptops, as a beginner encountered a problems that are still to be learnt, but still I would like to know.
I have two app, first is server on win wista:

#include "stdafx.h"
#include "winsock2.h"
#include <string>
#include <iostream>
 
//using namespace std;
 
 
int _tmain(int argc, _TCHAR* argv[])
{
  WSADATA wsaData;
  SOCKET ListeningSocket;
  SOCKET NewConnection;
 
  SOCKADDR_IN ServerAddr;
  SOCKADDR_IN ClientAddr;
  int Port=6000;
 
  WSAStartup(MAKEWORD(2,2),&wsaData);
 
  ListeningSocket=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
 
  ServerAddr.sin_family=AF_INET;
  ServerAddr.sin_port=htons(6000);
  ServerAddr.sin_addr.S_un.S_addr=htonl(INADDR_ANY);
 
  bind(ListeningSocket,(SOCKADDR*)&ServerAddr,sizeof(ServerAddr));
 
  listen(ListeningSocket,5);
 
  int nClient;
 
  while (true) {
    NewConnection=SOCKET_ERROR;
    while (NewConnection==SOCKET_ERROR) {
      NewConnection=accept(ListeningSocket,NULL,NULL);
    }
    std::cout<<"connected.."<<std::endl;
    break;
 
  }
  //cout<<inet_ntoa(ClientAddr.sin_addr)<<endl;
 
  return 0;
}

yes..I have two laptops with two diff os, and client is this:

#include <stdio.h>
#include <stdlib.h>
#include <sys/socket.h>
#include  <unistd.h>
#include <arpa/inet.h>
#include <stdlib.h>

/*
 * 
 */
int main(int argc, char** argv) {
    
    int clientSocked;
    
    struct sockaddr_in serverAddr;
    serverAddr.sin_family=AF_INET;
    serverAddr.sin_addr.s_addr=htonl(INADDR_ANY);//inet_addr("my ip");
    serverAddr.sin_port=htons(6000);
    
    if ((clientSocked=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP))<0)
        return (EXIT_FAILURE);
    if ((connect(clientSocked,(struct sockaddr*)&serverAddr,sizeof(serverAddr)))<0)
        return (EXIT_FAILURE);

    return (EXIT_SUCCESS);
}

this app doesn't work and i dont really know why. I assume i has something to do with the ip i am giving. I get the ip from internet and the ip is the same for both laptops..

And also to set an address for stuct sockadd_in address i need to use somehow different internal structure sockaddr_in.sin_addr.S_un.S_addr..
I am reading book 2windows networking" and this book gives me a diff internal structure sockadd_in.sin_addr.s_addr why is it changed?
