Problem mit Winsocks

[winsock noob]

Hallo ich kann an meinen Server immer nur 1 Befehl senden danach trennt der einfach immer die Verbindung:

Server

#include <windows.h> //Required for socket init
#include <iostream>
using namespace std;

//server
int main()
{
SOCKET kSock;
SOCKET client;
int len;

char buf[256];
WSAData wsdata; //Declare WSAData
WORD wsver=MAKEWORD(2, 0); //We want Winsock 2.0
int nret=WSAStartup(wsver, &wsdata); //Pass version 2.0 and pointer to implement

		if(nret != 0)
		{ //Init failed
		/*A successful return value should be 0 */
		std::cout<<"Startup failed, error code: "<<WSAGetLastError(); //Returns error code
		WSACleanup(); //Cleanup Winsock library
		return -1;
		}

std::cout<<"Init success\n";
kSock=socket(AF_INET, SOCK_STREAM, 0);

		if(kSock == INVALID_SOCKET)
		{
		std::cout<<"Socket init failed";
		return -1;
		}

std::cout<<"Socket initialized\n";
sockaddr_in sin;
sin.sin_port=htons(12345);
sin.sin_addr.s_addr=INADDR_ANY;
sin.sin_family=AF_INET;

		if(bind(kSock,(sockaddr*)&sin, sizeof(sin)) == SOCKET_ERROR)
		{
		std::cout<<"Failed to bind\n";
		WSACleanup(); //Cleanup Winsock library
		return -1;
		}

std::cout<<"Bind successful!\n";
while (listen(kSock, SOMAXCONN) == SOCKET_ERROR); //Loop in order to constantly listen
/* set the number of connections to SOMAXCONN, in which case the provider chooses a reasonable value (5 in Windows XP
Professional) */

  len = sizeof(sin);
  client=accept(kSock, (sockaddr*)&sin, &len);

  std::cout<<"Connection established!\n";

  send(client, buf, sizeof(buf), 0); //Send "Hello"

  recv(kSock, buf, sizeof(buf), 0);
  std::cout <<"Client Antwortet: "<< buf;

  system("PAUSE");

closesocket(client); //Close both socket handles
closesocket(kSock);
WSACleanup();
return 0;
}

Client

#include <windows.h> //Required for socket init
#include <iostream>
using namespace std;

//client
int main()

{
char buf[256];
int nret;

SOCKET kSock;

WSAData wsdata; //Declare WSAData
WORD wsver=MAKEWORD(2, 0); //We want Winsock 2.0

nret=WSAStartup(wsver, &wsdata); //Pass version 2.0 and pointer to implement

		if(nret != 0)
		{ //Init failed
		/*A successful return value should be 0 */
		std::cout<<"Startup failed, error code: "<<WSAGetLastError(); //Returns error code
		WSACleanup(); //Cleanup Winsock library
		return -1;
		}

std::cout<<"Init success\n";
	 kSock=socket(AF_INET, SOCK_STREAM, 0);

		if(kSock == INVALID_SOCKET)
		{
		std::cout<<"Socket init failed";
		return -1;
		}

std::cout<<"Socket initialized\n";

sockaddr_in sin;
sin.sin_port=htons(12345); //Connect to port 80
sin.sin_addr.s_addr=inet_addr("127.0.0.1"); //Connect to localhost
sin.sin_family=AF_INET;

			if(connect(kSock,(sockaddr*)&sin, sizeof(sin)) == SOCKET_ERROR)
			{ //Check the condition
			std::cout<<"Connect failed, error: "<<WSAGetLastError(); //Returns error code
			WSACleanup(); //Cleanup the library
			return -1;
			}

std::cout<<"Connection successful!\n";
  cout<<"Befehl eingeben: ";
  cin>>buf;

  send(kSock, buf, sizeof(buf), 0);

recv(kSock, buf, sizeof(buf), 0); //Receive "Hello" from server
cout<<"Connect ausgabe: "<<connect;
std::cout <<"Server Antwortet: "<<buf;

system("PAUSE");

closesocket(kSock);
return 0;
}

Hat jemand eine Ahnung was da falsch ist?

Ja Dein Server wartet auf eine Verbindung, sendet "Hallo" und empfängt einmal.
Danach ist das Programm zu ende.
Also musst Du in einer Schleife empfangen und erst beenden, wenn es gewünscht wird.

[was gesagt werden muss...]

Sie arbeiten mit Visual Studio 2005/2008? Klasse!
Testen Sie heute: Tastenkombination Strg + k + f!
Wirkt wunder, auch bei Leuten die keinen blassen Schimmer von jeglicher Formatierung von Quellcode haben!
