Ettercap, MAC to IP Address
I ran into a sticky problem today and was pleased at the solution. I’m trying to install Debian on a little NSLU2 box I bought. It’s a linux-based network attached storage device I’m hoping to replace my spare boy in the office with. It obtains and IP address using DHCP but doesn’t have an attached monitor, so short of assigned a static IP I had no way knowing what address was assigned.
Enter ettercap which is mainly used to simulate man in the middle attacks and act as a general network sniffer. Using it I was able to scan all machines on my local subnet and get the MAC to IP address mappings. Neat, but not something to try on a very large network.
