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.

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().
Linux includes a BPF JIT compiler which is disabled by default. Kernel-mode interpreters for that same virtual machine language are used in raw data link layer mechanisms in other operating systems, such as Tru64 Unix , and for socket filters in the Linux kernel and in the WinPcap and Npcap packet capture mechanism.
tcpdump is a data-network packet analyzer computer program that runs under a command line interface.It allows the user to display TCP/IP and other packets being transmitted or received over a network to which the computer is attached. [3]
The program runs under Linux, FreeBSD, NetBSD, OpenBSD, and macOS. The client can also run on Microsoft Windows, although, aside from external drones (see below), there's only one supported wireless hardware available as packet source. Distributed under the GNU General Public License, [2] Kismet is free software.
Beginning with version 4.1 of the Linux kernel, released in June 2015, the tcp_ecn_fallback mechanism [18]: §6.1.1.1 is enabled by default [19] when ECN is enabled (the value of 1). The fallback mechanism attempts ECN connectivity in the initial setup of outgoing connections, with a graceful fallback for transmissions without ECN capability ...
