Ettercap Filters for Packet Alteration
first of all, I want to say hello, since this is my first post.
I have a question about ETTERCAP.
I got a network which integrity must be tested. Some of the tests consist of alterating or dropping some packets.
Any information of the packet could be altered (addresses, checksum, payloads,...)
I tried with ETTERCAP filters, and at Layer 3 and 4 worked really well, since I could modify all the parameters I wanted.
Now I got a problem at Layer 2. I tried creating a filter that uses the MAC address as deciding parameter. The filter could be compiled without problems, but when I applied it, it did not filter as desired (even though the conditions were fulfilled).
Do you know if Ettercap supports Layer 2 filters??
