I'm creating a server/clinet, but I've a problem. If I boot the server and the client for the first time, everthing works fine. Then I close them, I boot them again in few seconds, and I receive e "connection refused" error in the client. I always boot the server first, and the client after. Here's the code. DoLogin is an easy function with 2 read and 2 write. What's wrong in this code?
server.c
int main(){
int ds_sock;
struct sockaddr_in my_addr;
ds_sock=socket(AF_INET,SOCK_STREAM,0);
memset(&my_addr,0,sizeof(my_addr));
my_addr.sin_family=AF_INET;
my_addr.sin_port=htons(25000);
my_addr.sin_addr.s_addr=INADDR_ANY;
if(bind(ds_sock,(struct sockaddr *)&my_addr,sizeof(my_addr))<0){
printf("Error in bind");
}
listen(ds_sock,2);
int ds_sock_acc;
struct sockaddr_in addr;
size_t sin_size = sizeof(struct sockaddr_in);
if((ds_sock_acc=accept(ds_sock,(struct sockaddr *)&addr,&sin_size))<1){
printf("Error accept");
}
printf("Connected\n");
char *usr = DoLogin(ds_sock_acc);
printf("%s is connected\n",usr);
close(ds_sock_acc);
close(ds_sock);
return 0;
}
client.c
int main(){
int ds_sock;
ds_sock = socket(AF_INET, SOCK_STREAM,0);
int ret;
struct sockaddr_in Eaddr;
Eaddr.sin_family = AF_INET;
Eaddr.sin_port = htons(25000);
Eaddr.sin_addr.s_addr=inet_addr("127.0.0.1");
ret = connect(ds_sock,(struct sockaddr *)&Eaddr,sizeof(Eaddr));
if(ret==-1){
printf("Error connect");
perror("error:");
exit(EXIT_FAILURE);
}
printf("Connect OK\n");
char *usr = DoLogin(ds_sock);
printf("Logged in as %s\n",usr);
close(ds_sock);
return 0;
}
