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.
Full packet capture appliances capture and record all Ethernet/IP activity, while filtered packet capture appliances capture only a subset of traffic based on a set of user-definable filters; such as IP address, MAC address or protocol. Unless using the packet capture appliance for a very specific purpose covered by the filter parameters, it is ...
[1] [2] [3] It accepts as input files produced by packet-capture programs, including tcpdump, Wireshark, and snoop. tcptrace can produce several different types of output containing information on each connection seen, such as elapsed time, bytes and segments sent and received, retransmissions, round trip times, window advertisements, and ...

In IEEE 802 networks such as Ethernet or IEEE 802.11, each frame includes a destination MAC address. 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 ...
However, the concept behind PCAP-over-IP was mentioned already in 2008 as part of a feature request for Wireshark. [3] The need for this feature was motivated as follows: "This feature is useful when the capture is generated on a machine which does not have much storage (e.g. embedded system).
To establish the connection between IP and MAC address, it is useful to take a closer look at auxiliary network protocols. The Address Resolution Protocol (ARP) tables list the MAC addresses with the corresponding IP addresses. To collect data on this layer, the network interface card (NIC) of a host can be put into "promiscuous mode". In so ...
In Mac OS X 10.4 and later releases, the drivers for AirPort Extreme network adapters allow the adapter to be put into monitor mode. Libpcap 1.0.0 and later provides an API to select monitor mode when capturing on those operating systems.
