 Posted: Tue Sep 07, 2010 2:25 pm Post subject: ARP Sending in C++ |
 |
|
I was wondering how would i send an arp request that i have built in c++?
so far i got here:
| Code: |
typedef struct arp {
unsigned short htype;
unsigned short ptype;
unsigned char hlen;
unsigned char plen;
unsigned short operation;
unsigned int source_mac;
unsigned short source_mac_con;
unsigned int source_ip;
unsigned short dest_mac;
unsigned int dest_mac_con;
unsigned int dest_ip;
} *ARP;
void SendARPRequest( void ) {
ARP arp_packet;
arp_packet = (ARP) malloc( sizeof arp );
arp_packet->htype = 1;
arp_packet->ptype = 0x0800;
arp_packet->hlen = 48;
arp_packet->plen = 32;
arp_packet->operation = 1;
arp_packet->source_mac = 0x000129d5;
arp_packet->source_mac_con = 0x98ef;
arp_packet->source_ip = 0x0a000001;
arp_packet->dest_mac = 0x00000000;
arp_packet->dest_mac_con = 0x0000;
arp_packet->dest_ip = 0x0a000007;
}
|
I created the arp structure as far as i guess it is.
but now where do i go?
how do i turn it into my network card to move on to the network?
i'm guessing there is no use in sockets in that level of frames / packets
any help would be great

Why are you using C-style code in C++ code?
Anyways, I think you can do this with raw sockets, but you should know that sending raw sockets on Windows is disabled.
You could write a driver or use one, I belive that the library WinPCap should help you.

Yea, I know winpcap and wondered if i could just write one in myself,
but i don't really know how to accomplish that.
by saying driver do you mean kmd?

| Yeah, kernel-level.

Windows sockets do not allow ARP packets from usermode. So yes you need a kernelmode driver. The easiest would be to use WinPCap, though I'm not sure if it can send packets instead of only 'sniffing'.
It's probably quite difficult to make such a driver yourself if you've never made a driver before.

Yea, that's pretty much what i want to get into right now.
I'd like to step into the KMD subject not only for that goal, but for knowing it properly.
got any good tutorials for beginners?

| How about using SendARP winapi?
