A packet analyzer used for intercepting traffic on wireless networks is known as a wireless analyzer - those designed specifically for Wi-Fi networks are Wi-Fi analyzers. [ a ] While a packet analyzer can also be referred to as a network analyzer or protocol analyzer these terms can also have other meanings.
Another method to monitor networks is to use port mirroring (called "SPAN", for Switched Port Analyzer, by vendors such as Cisco, [1] and given other names, such MLXe telemetry by Brocade Communications and other vendors)(also known as MIRROR port) or a monitoring protocol such as TZSP on routers and switches. This is a low-cost alternative to ...

The Sniffer [1] was a computer network packet and protocol analyzer developed and first sold in 1986 by Network General Corporation [2] of Mountain View, CA. By 1994 the Sniffer had become the market leader [ 3 ] in high-end protocol analyzers.
The program can also be used to detect probes or attacks, including, but not limited to, operating system fingerprinting attempts, semantic URL attacks, buffer overflows, server message block probes, and stealth port scans. [11] Snort can be configured in three main modes: 1. sniffer, 2. packet logger, and 3. network intrusion detection. [12]
In promiscuous mode, some software might send responses to frames even though they were addressed to another machine. However, experienced sniffers can prevent this (e.g., using carefully designed firewall settings). An example is sending a ping (ICMP echo request) with the wrong MAC address but the right IP address.
The Carnivore system was a Microsoft Windows-based workstation with packet-sniffing software and a removable Jaz disk drive. [4] This computer must be physically installed at an Internet service provider (ISP) or other location where it can "sniff" traffic on a LAN segment to look for email messages in transit. The technology itself was not ...
