probleme de communication entre deux programme

re salut le dernier message que j ai poster c etait pour les socket et la librairie "libwsock.a" mais sayer j ai passer cette etape j ai reussi a faire un serveur qui envoie"hello word" a un client maintenan j aimerai bien pouvoir repondre a partir du client
                le code clien est:
                *******************


#include <cstdlib>
#include <iostream>
#include <winsock2.h>
#include<string.h>
using namespace std;

main(int argc, char *argv[])
{
    WSADATA WSAData;
WSAStartup(MAKEWORD(2,0), &WSAData);
SOCKET sock;
SOCKADDR_IN sin;
char buffer[255],t[255];
sin.sin_addr.s_addr = inet_addr("192.168.2.2");
sin.sin_family = AF_INET;
sin.sin_port = htons(4148);
sock = socket(AF_INET,SOCK_STREAM,0);
bind(sock, (SOCKADDR *)&sin, sizeof(sin));
connect(sock, (SOCKADDR *)&sin, sizeof(sin));
recv(sock, buffer, 254, 0);
printf("%s\n",buffer);
printf("\n\nsaisir la phrase a envoyer\n");
scanf("%s",t);           \\ici on rentre la variable a renvoyer o serveur
send(sock, t, 256, 0);    \\on envoie
closesocket(sock);
WSACleanup();
  system("PAUSE");
    return EXIT_SUCCESS;
}


                  et voici le code du serveur
                   ************************

#include <cstdlib>
#include <iostream>
#include <winsock2.h>
#include<string.h>
#include<stdio.h>
#include<stdlib.h>
using namespace std;

main(int argc, char *argv[])
{
    WSADATA WSAData;
WSAStartup(MAKEWORD(2,0), &WSAData);
SOCKET sock;
SOCKADDR_IN sin;
SOCKADDR_IN csin;
SOCKET csock;
char buffer[255],t[255];
sin.sin_addr.s_addr = htonl(INADDR_ANY);

sin.sin_family = AF_INET;
sin.sin_port = htons(4148);
sock = socket(AF_INET,SOCK_STREAM,0);
bind(sock, (SOCKADDR *)&sin, sizeof(sin));

listen(sock, 2);

int sinsize = sizeof(csin);
system("pause");
while(1)
{
if((csock = accept(sock, (SOCKADDR *)&csin, &sinsize)) != INVALID_SOCKET)
{
send(csock, "Hello world!\r\n", 14, 0);
printf("evoie reussi");
}
recv(sock,buffer,strlen(buffer),MSG_PEEK);         \\censer recevoir          \                                                    \les info envoyer par le \                                                      \client
printf("message :                        %s\n",buffer);
}

    system("PAUSE");
    return EXIT_SUCCESS;
}



  en fait le probleme que je rencontre est que mon serveur m affiche des caractere bidon a la place de menvoyer le string du client



merci pour vaut reponse
