Conversion of Ethernet address to readable form?

Question

struct ethernet_header
{
    u_char ether_dhost[ ETHER_ADDR_LEN];

    u_char ether_shost[ETHER_ADDR_LEN];

    u_short ether_type;
};

for(i = 0;i <6; i++)
  printf(         


        

Answer 1

I think the best way would be to use ether_ntoa() which is available on just about any *nix operating system (available in net/ethernet.h). The following works quite well for me.

char *addr;
struct ether_addr host;

memcpy(&host, ethernet->ether_dhost, sizeof(host));
addr = ether_ntoa(&host);
