Address family not supported by protocol family

Hi,

I compiled with no error a C program, than I tryed to execute it and than I get this error:

connessione al server fallita: Address family not supported by protocol family


What does it mean?

Why I get this error only on Mac os x while on Ubuntu the program works?

The code is:
/*
* EsameClient.c
*
*/

#include <stdlib.h>
#include <ctype.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>

#define NR 3
#define MAXLENGTH 80
#define SERVER_PORT 1313

int main (unsigned argc, char **argv)
{
int sockfd;
struct sockaddr_in server={AF_INET,htons(SERVER_PORT),INADDR_ANY};
int i=0,len;
char buf[MAXLENGTH],c;
int buffer[NR], stato;

/* Controllo Parametri Passati da Terminale */
if(argc != 4) // argv[1] -> argv[3] sono le risorse
{
perror("Chiamata corretta del programma:\nnome-programma <risorsa1> <risorsa2> <risorsa3> \n<risorsai> deve essere un intero positivo");
exit(1);
}

/* impostazione del transport end point */
if((sockfd = socket(AF_INET, SOCK_STREAM, 0)) == -1)
{
perror("chiamata alla system call socket fallita");
exit(1);
}
/* connessione al server */
if(connect(sockfd,(struct sockaddr *)&server,sizeof server)==-1)
{
perror("connessione al server fallita");
exit(2);
}


/* ricezione e stampa a video del messaggio di benvenuto del server */
if(recv(sockfd,buf,27,0)>0)
{
buf[27]='\0';
printf("%s",buf);
}
else
{
perror("Connessione al server interrotta");
exit(3);
}

/* acquisizione della stringa da standard input */
/* while((c=getchar())!='\n' && i<MAXLENGTH)
buf[i++]=c;
buf[i]='\0';
len=strlen(buf); */

// Imposta buffer e len
for(i=0; i<NR;i++)
buffer[i]=argv[i+1];
len=sizeof(buffer); // size?? o # = 3/////////////////////////////////////////////////////


/* invio e ricezione della stringa */
if(send(sockfd,buffer,len,0)==-1) // Se send ritorna -1 = errore
{
perror("Errore nell'invio della richiesta risorse al server");
exit(4);
}
if(recv(sockfd,&stato,len,0)>0)
{
printf("%d\n",stato);
}
else
{
perror("Connessione al server interrotta");
exit(3);
}

/* chiusura della connessione */
close(sockfd);
}

Google suggests Ettercap :: View topic - ettercap & MacOS X (10.2.6) not finding other machines..

What you are experiencing is the standard 10.2.x problem.
Apple have screwed up their BPF (Berkeley Packet Filter) implementation.

One of the problems with your code is that you are using IP address INADDR_ANY. This allows your program to work without knowing the IP address of the system it is running on, or, in the case of a system with multiple network interfaces, it allows your server to receive packets destined to any of the interfaces. However there are issues with using INADDR_ANY. Do a Google search on INADDR_ANY for more information.

I suggest that you bind to a specific server address.
