dsniff is a suite of utilities that are useful for penetration testing. It consists of the following programs: arpredirect intercepts packets from a target host on the LAN intended for another host on the LAN by forging ARP replies. findgw determines the local gateway of an unknown network via passive sniffing. macof floods the local network with random MAC addresses. tcpkill kills specified in-progress TCP connections. dsniff is a simple password sniffer which handles many protocols. mailsnarf outputs all messages sniffed from SMTP traffic in Berkeley mbox format. webspy sends URLs sniffed from a client to your local Netscape browser for display, updated in real-time.
