[C] Programme Serveur/Client - Creepy_p0ney - 10-10-2012
Salut,j'ai donc réusi à programmer mon serveur multi clients, mais le problème se pose pour le client car en effet, mon clients fonctionne quand je me connecte au serveur (qui est sur mon linux) avec le client(qui est sur mon linux) le truc c'est que quand je me connecte avec mon client sous win ça ne fonctionne pas!! (il envoie les données mais ne les reçoit pas).
voici le code de mon srv
Code :
#include <sys/types.h>
#include <netinet/in.h>
#include <netdb.h>
#include <sys/socket.h>
#include <sys/wait.h>
#include <unistd.h>
#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <string.h>
typedef struct
{
int sock;
char name[64];
}Client;
int main(){
int reals;
int sin_size;
int sockfd;
struct sockaddr_in their_addr[5];
int i=0;
int ret=0;
char buf[64];
char msg[64];
int k=0;
int m=0;
int max=0;
Client clients[5];
fd_set fd;
struct sockaddr *addr;
char *log="tim";
struct sockaddr_in my_addr;
pid_t pid;
if((sockfd=socket(AF_INET,SOCK_STREAM,0))<0){
perror("socket");
exit(1);
}
my_addr.sin_family=AF_INET;
my_addr.sin_port=htons(2300);
my_addr.sin_addr.s_addr=INADDR_ANY;
if(bind(sockfd,(struct sockaddr *)&my_addr,sizeof(struct sockaddr_in))<0){
perror("bind");
exit(1);
}
listen(sockfd,5);
printf("attente d'un client");
sin_size = sizeof(struct sockaddr_in);
printf("%d\n",i);
while(1){
int l=0;
int n=0;
FD_ZERO(&fd);
FD_SET(sockfd,&fd);
for(l=0;l<i;l++){
FD_SET(clients[l].sock,&fd);
}
printf("nous y sommes3\n");
for(n=0;n<i;n++){
if(max<clients[n].sock){
max=clients[n].sock;
}
}
if(max<sockfd)
max=sockfd;
printf("%d",max);
if((ret=select(max+1,&fd,NULL,NULL,NULL))==-1){
perror("select");
exit(1);
}
printf("nous y sommes2\n");
if(FD_ISSET(sockfd,&fd)){
printf("here we are\n");
sin_size=sizeof(struct sockaddr_in);
clients[i].sock=accept(sockfd,(struct sockaddr *)&their_addr[i],&sin_size);
send(clients[i].sock,"login :",64,0);
reals=recv(clients[i].sock,buf,64,0);
buf[reals]='\0';
strncpy(clients[i].name, buf, 64 - 1);
i++;
}
else if(ret==0){
printf("problem?");
}
else{
printf("here we are9");
for(k=0;k<i;k++){
if(FD_ISSET(clients[k].sock,&fd)){
int j=0;
printf("here we are5\n");
reals=recv(clients[k].sock,buf,64,0);
printf("here we are6\n");
if(reals==0){
close(clients[k].sock);
i--;
}
else{
buf[reals]='\0';
printf("%s",buf);
printf("here we are7\n");
strncpy(msg,clients[k].name,64-1);
strncat(msg,buf,64-strlen(msg)-1);
