Answer:
Examples of network sniffing tools include:
1. Wireshark: A widely-used network protocol analyzer that captures and displays the data traveling back and forth on a network in real-time.
2. tcpdump: A command-line packet analyzer that captures network packets and displays them in a human-readable format.
3. Ettercap: A comprehensive suite for man-in-the-middle attacks on LAN. It supports active and passive dissection of many protocols and includes many features for network and host analysis.
4. Snort: An open-source intrusion prevention system and network monitoring software that can perform packet logging and real-time traffic analysis on IP networks.
5. Cain & Abel: A password recovery tool that can be used for network sniffing, ARP poisoning, and other security tasks.
6. Nmap: A powerful network scanning tool that can be used for network discovery and security auditing. While not primarily a sniffer, it can capture packets and perform various network reconnaissance tasks.
7. NetworkMiner: A network forensic analysis tool for Windows that can parse pcap files and display network traffic statistics.
These tools can be used for legitimate network monitoring and troubleshooting purposes, but they can also be used maliciously for unauthorized access to sensitive information, so it's important to use them responsibly and ethically.
