HI,

Thanks Andrew.

config decode_data_link will replace -e in snort command.
The Mac-address will be printed on the screen but it will not be saved in
the snort.u2.xxx file.


The mac address is saved in the file if your listening on a ethernet
interface and the
packet that you initialy captured has a ethernet header.


So , what should i do to save it in the file ?

Try adding:

config decode_data_link

to snort.conf

You probably won’t get the mac address of the host.  You will only get
the mac address of the device that last handled the packet before Snort saw
it.

Thanks.

So what i need is to save in snort database, when an attack is
deteckted, the mac-addresses of host.
So how can i do that ?

Snort can dump the last mac address that it sees when it sniffs the
packet, use the “-e” command line tag.
