Hi everybody !
First of all, thanks Loris for all of your answers, they helped me a lot : )
But now I have another doubt:
I copied the example program pcap_filter and now I am trying to extend it to print
some parts of the ethernet header (like in the tutorial of Martin Casado).
So the first thing I did was to copy the ethernet header definition:
struct ether_header
{
u_int8_t ether_dhost[ETH_ALEN]; /* destination eth addr */
u_int8_t ether_shost[ETH_ALEN]; /* source ether addr */
u_int16_t ether_type; /* packet type ID field */
} __attribute__ ((__packed__));
But I could not find a library in Windows which defines the parameter u_int8_t.
Then, I found out in tcpdump code the file "bittypes.h" which defines this u_int8_t
but just including this file in my workspace does not help. There is the variable
"SIZEOF_CHAR" in the beginning of the file, which I could not find where it comes
from. Is it (SIZEOF_CHAR) defined when the config.h file is created ? How can I get
this config.h (I just can find config.h.in and etc)?
I found out then in Unix that u_int8_t is defined in the file "sys\types.h".
Why in "bittypes.h" the definition of u_int8_t is dependent on the value of
SIZEOF_CHAR and in the "sys\types.h" not ?
I hope you could understand my question : ) I would be very glad if somebody could
answer to me.
Thanks a lot !
Beatriz.
