I've set up the apache server on localhost (127.0.0.1). I've downloaded PackETH to perform a DoS attack. So PackETH wants MAC-HEADER of the destination and source. And I don't know, where to find them.
You can use the
ipconfig /all command in the Windows command prompt and then copy your Physical Address, also known as MAC address. I am not sure if PackETH will work on the same PC though.
More detail here.
If you're using Linux, open terminal and run
ifconfig command. You'll find the MAC address under "HWaddr" (Hardware Address)
You can find additional details here.
TMHO. I think you better use 2 virtual machines with NAT Network and not attack your local machine with external tools you did not wrote yourself.
