Getting ARP table on iPhone/iPad

Question

I am trying to get the ARP entries on my iPad like here.

When compiling the code to run on my iPad (so not the simulator) I am getting missing header error messages.

Answer 1

After importing <netinet/if_ether.h>, you should edit it and change the line

#include <net/if_arp.h>

to

#include "if_arp.h"

and then import <net/if_arp.h> in your project as well. This should fix that error.

Anyway the headers you need to import to compile the code you posted are:

#include "if_ether.h"
#include "route.h"
#include "if_arp.h"
#include "if_dl.h"

Hope this helps =)

EDIT:

You need to "Add files to project", not simply importing it with #import or #include. You can find above files from following links: Files under "netinet" Files under "net"

Answer 2

#include <net/ethernet.h>

instead of messing with the original headers. More info here: Implicit declaration of function 'ether_ntoa' is invalid in C99
