In non-promiscuous mode, when a NIC receives a frame, it drops it unless the frame is addressed to that NIC's MAC address or is a broadcast or multicast addressed frame. In promiscuous mode, however, the NIC allows all frames through, thus allowing the computer to read frames intended for other machines or network devices.
CommView puts the network adapter into promiscuous mode and captures network traffic. [3] It also supports capturing packets from dial-up and virtual adapters (e.g. ADSL or 3G modems), as well as capturing loopback traffic. Captured traffic is then analyzed and the application displays network statistics and individual packets.
This type of promiscuous traffic, due to a lack of address filtering, has been a recurring issue with certain Unix and Linux kernels, [2] [3] but has never been reported on Microsoft Windows operating systems post Windows XP. Another form of promiscuous traffic occurs when two different applications happen to listen on the same group address.
Wireshark is very similar to tcpdump, but has a graphical front-end and integrated sorting and filtering options.. Wireshark lets the user put network interface controllers into promiscuous mode (if supported by the network interface controller), so they can see all the traffic visible on that interface including unicast traffic not sent to that network interface controller's MAC address.
Ettercap is a free and open source network security tool for man-in-the-middle attacks on a LAN.It can be used for computer network protocol analysis and security auditing.It runs on various Unix-like operating systems including Linux, Mac OS X, BSD and Solaris, and on Microsoft Windows.
This tapping method consists in enabling promiscuous mode on the device that is used for the monitoring and attaching it to a network hub. This works well with older LAN technologies such as 10BASE2, FDDI, and Token Ring. On such networks, any host can automatically see what all other hosts were doing by enabling promiscuous mode.

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 ...
