Kismet differs from other wireless network detectors in working passively. Namely, without sending any loggable packets, it is able to detect the presence of both wireless access points and wireless clients, and to associate them with each other. It is also the most widely used and up to date open source wireless monitoring tool. [citation needed]
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.

A network tap is an even more reliable solution than to use a monitoring port since taps are less likely to drop packets during high traffic load. On wireless LANs , traffic can be captured on one channel at a time, or by using multiple adapters, on several channels simultaneously.
iproute2 is a collection of userspace utilities for controlling and monitoring various aspects of networking in the Linux kernel, including routing, network interfaces, tunnels, traffic control, and network-related device drivers.
netsniff-ng is a free Linux network analyzer and networking toolkit originally written by Daniel Borkmann. Its gain of performance is reached by zero-copy mechanisms for network packets (RX_RING, TX_RING), [3] so that the Linux kernel does not need to copy packets from kernel space to user space via system calls such as recvmsg().
ngrep (network grep) is a network packet analyzer written by Jordan Ritter.It has a command-line interface, and relies upon the pcap library and the GNU regex library.. ngrep supports Berkeley Packet Filter logic to select network sources or destinations or protocols, and also allows matching patterns or regular expressions in the data payload of packets using GNU grep syntax, showing packet ...
A common usage is to monitor network traffic by polling a network switch or router interface via Simple Network Management Protocol (SNMP). The Cacti end user front end supports both User and User Groups security models and supports Role Based Access Control (RBAC) for access to not only monitoring data, but various areas of the user interface.
