Re: char * to struct ether_addr *

yes - there is. check libnet-functions.h.

libnet 1.1.0

u_char * libnet_hex_aton(char *s, int *len);

libnet 1.1.1

u_int8_t * libnet_hex_aton(int8_t *s, int *len);

if you use a GNU/Linux system and you want to do it libnet 
independent - look in '/usr/include/netinet/ether.h' for a
function called ether_aton.

example (not plattform independent...)

#include <netinet/ether.h>
 
struct ether_addr *ea;

if ((ea = ether_aton(spoofed_mac)) == NULL){
	printf("ether_aton error: invalid mac addr\n");
}

now you've got a valid network byte order mac.

hope this helps ...
