i have tried to listen to the raw packets by using the following program
.on running it just keeps on waiting for any packet to come even when
there is traffic .
i am running the program as a root.
the program:
---------------------------------------------------------------------------------
include<sys/types.h>
#include<sys/socket.h>
#include<net/if_packet.h>
#include<linux/if_ether.h>
#include<netinet/in.h>
#include<unistd.h>
#include<stdlib.h>
#include<stdio.h>
main()
{
int addlen;
struct datagram {
struct iphdr *ip;
char data[100];
};
struct datagram ipdgram;
int cont,create_socket,new_socket,addrlen;
int bufsize = 1024;
char *buffer = malloc(bufsize);
struct sockaddr_in address;
printf("\x1B[2J");//clear screen
if ((create_socket = socket(PF_PACKET,SOCK_RAW,ETH_P_ALL)) > 0)
printf("The socket was created\n");
while(1)
{
read(create_socket,(struct datagram*)&ipdgram,sizeof(ipdgram));
//printf("%s",ipdgram.data);
}
printf("%s",ipdgram.data);
close(create_socket);
}
---------------------------------------------------------------------------------
on running ::
---------------------------------------------------------------------------------
the socket is created
---------------------------------------------------------------------------------
and like this it keeps on waiting
