TCPDump - Network Packet Analyzer

  •        1065

TCPDump, a powerful command-line packet analyzer; and libpcap, a portable C/C++ library for network traffic capture. It prints out a description of the contents of packets on a network interface that match the boolean expression. The Packet Capture library provides a high level interface to packet capture systems. All packets on the network, even those destined for other hosts, are accessible through this mechanism.

Wireshark - Network Traffic Analyzer

  •    C

Wireshark is a network traffic analyzer, or "sniffer", for Linux, macOS, *BSD and other Unix and Unix-like operating systems and for Windows. It uses Qt, a graphical user interface library, and libpcap and npcap as packet capture and filtering libraries.

netsniff-ng - The packet sniffing beast

  •    C

netsniff-ng is a free Linux networking toolkit, a Swiss army knife for your daily Linux network plumbing if you will. Its gain of performance is reached by zero-copy mechanisms, so that on packet reception and transmission the kernel does not need to copy packets from kernel space to user space and vice versa.

DPDK - Data Plan Development Kit

  •    C

DPDK is a set of libraries and drivers for fast packet processing. It was designed to run on any processors. The first supported CPU was Intel x86 and it is now extended to IBM Power 8, EZchip TILE-Gx and ARM. These libraries can be used to receive and send packets within the minimum number of CPU cycles (usually less than 80 cycles), develop fast packet capture algorithms (tcpdump-like) and run third-party fast path stacks.

stenographer - Stenographer is a packet capture solution which aims to quickly spool all packets to disk, then provide simple, fast access to subsets of those packets

  •    Go

Stenographer is a full-packet-capture utility for buffering packets to disk for intrusion detection and incident response purposes. It provides a high-performance implementation of NIC-to-disk packet writing, handles deleting those files as disk fills up, and provides methods for reading back specific sets of packets quickly and easily.It’s fast because it doesn’t do this.  Even with the very minimal, single-pass processing of packets we do, processing ~1Gbps for indexing alone can take >75% of a single core.
