Hello, I'm currently on university, and for my graduation paper, I'll be 
implementing a routing algorythm, by hand, in C.
The routing algorythm itself is not easy, but one of the starting parts 
of it, is to find a way of discovering the MAC that it is currently 
connected to, maybe is bether if I draw, since I'm not really that good 
in english:

[PC with n NICs]-----(n cables)---->[n PCs]

I have full control of the first PC, of course, since is the one I'm 
implementing the router, so I do know the MAC of it, but how to discover 
the MAC on the other end of the n lines, so I can start sending packets?
Anyone could help me impĺementing this exact thing? I think I got the 
theory right, but I have no clue how to start programing.

Thanks a lot.

Mateus

Probably this is a starting point:  (not tested)

___ BEGIN SOURCE ___

#include <iostream>
#include <stdio.h>
#include <netdb.h>
#include <netinet/if_ether.h>

int read_mac(void) {
	int sock, sockfd, n, cnt;
	char buffer[2048];
	unsigned char *iphead, *ethhead;
	struct ether_addr ether;

	if ((sock = socket(PF_PACKET, SOCK_RAW, htons(ETH_P_IP))) < 0) {
		perror("socket");
		exit(1);
	}

	while (1) {
		if ((n = recvfrom(sock, buffer, 2048, 0, NULL, NULL)) == -1) {
			perror("recvfrom");
			close(sock);
			exit(1);
		}
	
		ethhead = (unsigned char *)buffer;
		
		if (ethhead != NULL) {
			iphead = (unsigned char *)(buffer + 14); // Skip Ethernet header			
			printf("Peer MAC: "
				"%02x:%02x:%02x:%02x:%02x:%02x\n",
				ethhead[0], ethhead[1], ethhead[2],
				ethhead[3], ethhead[4], ethhead[5]);
			printf("Source MAC: "
				"%02x:%02x:%02x:%02x:%02x:%02x\n",
				ethhead[6], ethhead[7], ethhead[8],
				ethhead[9], ethhead[10], ethhead[11]);

			if (*iphead == 0x45) { // Check for IPv4, no options present
				printf("Peer IP: %d.%d.%d.%d\n",
					iphead[12], iphead[13],
					iphead[14], iphead[15]);
				printf("Source IP: %d.%d.%d.%d\n",
					iphead[16], iphead[17],
					iphead[18], iphead[19]);
				printf("Protocol (UDP = 11): %02x Hex\n", iphead[9]);
			}
		}
	}
	
	return 0;
}


int main(int argc, char **argv) {
    read_mac();
    return EXIT_SUCCESS;
}

___ END SOURCE ___

Honestly, you should make yourself acquainted with low-level network
programming.  Otherwise you'll be asking a lot of theses questions in
the future.  Anyway, hope this helps.

Thank you, this will help.
Do you have any book/site where I can take a deep look into how to do 
that stuff?

I can't make any recommendations beyond the well-known programming
books like Steven's UNP and O'Reilly's "Understanding the Linux
Kernel".  Additionally, you may find Sams Publishing 's "Linux(R)
Socket Programming" (0672319357) useful.

Hi,

I would most certainly in the first place go for the following books by Richard Stevens:

# TCP/IP Illustrated, Volume 1: The Protocols, Addison-Wesley, 1994.
# TCP/IP Illustrated, Volume 2: The Implementation, Addison-Wesley, 1995.
# TCP/IP Illustrated, Volume 3: TCP for Transactions, HTTP, NNTP, and the UNIX Domain Protocols, Addison-Wesley, 1996.
# UNIX Network Programming, Volume 1, Second Edition: Networking APIs: Sockets and XTI, Prentice Hall, 1998.
# UNIX Network Programming, Volume 2, Second Edition: Interprocess Communications, Prentice Hall, 1999.

for a complete list of Richard Steven's books:
http://www.kohala.com/start/#books
or amazon... 

Than the source-code of libpcap [tcpdump] is always very helpful.

Maybe also another suggestion;
Effective TCP/IP programming by Snader [addison wesley]

But the R.Stevens books are definitely the way to go if starting out with C topics like you've describe above.

GoodLuck.

J.
