On a corporate LAN with Ethernet switching, you need to discreetly capture all employee web traffic. After enabling net.ipv4.ip_forward on your Kali box, you start a tool that continually sends forged ARP replies mapping the default gateway's IP to your MAC address so hosts route through you. Which utility is purpose-built for this task?
The scenario describes classic ARP cache poisoning to place the attacker in the traffic path. The dsniff utility arpspoof is designed specifically for continuous ARP spoofing; it needs only an interface and target or network to operate. Netstat simply lists connections, hping3 crafts TCP/UDP/ICMP packets rather than ARP floods, and Nmap's --spoof-mac option changes the sender's MAC in probes without poisoning victim caches.
