20-53-52-43-00-02. Now machine A has updated its ARP cache, I believe that the MAC address of the machine whose IP address is 10.0.0.3 is 20-53-52-43-00-02. When machine A sends an FTP command -- ftp10.0.0.3, the data packet is sent to the Switch. The Switch checks the destination address in the data packet and finds that the MAC address is 20-53-52-43-00-02, so he sent the packet to machine B. You can fool both of them to complete man-in-the-middle spoofing attacks. Of course, you still need t
