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.
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.
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 ...
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.
It is also the top-rated packet sniffer in the Insecure.Org network security tools survey [20] and was the SourceForge Project of the Month in August 2010. [21] Combs continues to maintain the overall code of Wireshark and issue releases of new versions of the software. The product website lists more than 2000 contributing authors. [22]
Using port mirroring (sometimes called Span Port) is a very common way, as well as physically inserting a network tap which duplicates and sends the data stream to an analyzer tool for inspection. Deep Packet Inspection (and filtering) enables advanced network management, user service, and security functions as well as internet data mining ...

Monitor mode, or RFMON (Radio Frequency MONitor) mode, allows a computer with a wireless network interface controller (WNIC) to monitor all traffic received on a wireless channel. Unlike promiscuous mode , which is also used for packet sniffing , monitor mode allows packets to be captured without having to associate with an access point or ad ...
