linux sockets only reciving first chunk of data - c++

Question

I have two programs, on is server and only listening and the client is talking. I send 1mbytes of data in chunks of 64bytes each. I will get the first chunk of 64byte but then my server exits because it failed to get other data. My client is sending all of the data.
void ServerLinux::Receive(){
int sock = 0;
struct sockaddr_in server;
char buffer[this->packageLength];
if ((sock = socket(PF_INET, SOCK_STREAM, IPPROTO_TCP)) < 0) {
this->Die("Failed to create socket");
}
memset(&server, 0, sizeof(server));
server.sin_family = AF_INET;
server.sin_addr.s_addr = htonl(INADDR_ANY);
server.sin_port = htons(this->port);
if(bind(sock, (struct sockaddr *) &server, sizeof(server)) < 0){
this->Die("Failed to bind the server socket");
}
if(listen(sock, 1) < 0){
this->Die("Failed to listen on server socket");
}
int clientSocket = 0;
struct sockaddr_in client;
socklen_t size = sizeof(client);
if((clientSocket = accept(sock, (struct sockaddr *) &client, &size)) < 0){
this->Die("Failed to accept client");
}
int received = -1;
//This is fine data is recived
if((received = recv(clientSocket, buffer, this->packageLength,0)) < 0){
this->Die("Failed to receive initial bytes from client");
}
std::cout << "Received!" << std::endl;
//Data is not received in this while loop
while(received > 0){
if((received = recv(sock, buffer, this->packageLength,0)) < 0){
this->Die("Failed to receive additional bytes frin client");
}
std::cout << "Received!" << std::endl;
}
}

Why don't you use the same arguments for recv?
works: recv(clientSocket, buffer, this->packageLength,0)
doesn't work recv(sock, buffer, this->packageLength,0)
Change sock to clientSocket.
