Ettercap-A suite for man in the middle attacks on LAN. It features sniffing of live
connections, content filtering on the fly and many other interesting tricks.It supports
active and passive dissection of many protocols (even ciphered ones) and includes
many feature for network and host analysis.

nmap- Nmap ("Network Mapper") is a free and open source utility for network exploration or
security auditing. Many systems and network administrators also find it useful for tasks
such as network inventory, managing service upgrade schedules, and monitoring host or
service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are
available on the network, what services (application name and version) those hosts are
offering, what operating systems (and OS versions) they are running, what type of
packet filters/firewalls are in use, and dozens of other characteristics. It was designed to
rapidly scan large networks, but works fine against single hosts. Nmap runs on all major
computer operating systems, and both console and graphical versions are available.

Wireshark -wirshark is the world's foremost network protocol analyzer, and is the de facto
(and often de jure) standard across many industries and educational institutions.

Cain & able-Cain & Abel is a password recovery tool for Microsoft Operating Systems. It allows
easy recovery of various kind of passwords by sniffing the network, cracking
encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks,
recording VoIP conversations, decoding scrambled passwords, recovering wireless
network keys, revealing password boxes, uncovering cached passwords and
analyzing routing protocols. The program does not exploit any software
vulnerabilities or bugs that could not be fixed with little effort. It covers some
security aspects/weakness present in protocol's standards, authentication
methods and caching mechanisms; its main purpose is the simplified recovery of
passwords and credentials from various sources, however it also ships some "non
standard" utilities for Microsoft Windows users.

The latest version is faster and contains a lot of new features like APR (Arp Poison Routing) which enables sniffing on switched LANs and Man-in-the-Middle attacks. The sniffer in this version can also analyze encrypted protocols such as SSH-1 and HTTPS, and contains filters to capture credentials from a wide range of authentication mechanisms. The new version also ships routing protocols authentication monitors and routes extractors, dictionary and brute-force crackers for all common hashing algorithms and for several specific authentications, password/hash calculators, cryptanalysis attacks, password decoders and some not so common utilities related to network and system security.
