npcap - Nmap Project's packet sniffing library for Windows, based on WinPcap/Libpcap improved with NDIS 6 and LWF

  •    C

Npcap is an update of WinPcap to NDIS 6 Light-Weight Filter (LWF) technique. It supports Windows Vista, 7, 8 and 10. It is sponsored by the Nmap Project and developed by Yang Luo under Google Summer of Code 2013 and 2015. It also received many helpful tests from Wireshark, libpcap and NetScanTools.Run git clone https://github.com/nmap/npcap: pull this repo. This repo contains libpcap as a submodule, so make sure that you have also pulled all the submodules.

TCPDump - Network Packet Analyzer

  •    C

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.

Snort - Network Intrusion Prevention and Detection System

  •    C

Snort is an open source network intrusion prevention and detection system (IDS/IPS) developed by Sourcefire. Snort can perform protocol analysis and content searching/matching. It can be used to detect a variety of attacks and probes, such as buffer overflows, stealth port scans, CGI attacks, SMB probes, OS fingerprinting attempts, and much more.




wireshark - Read-only mirror of Wireshark's Git repository

  •    C

Wireshark is a network traffic analyzer, or "sniffer", for Unix and Unix-like operating systems. It uses Qt, a graphical user interface library, and libpcap, a packet capture and filtering library. The Wireshark distribution also comes with TShark, which is a line-oriented sniffer (similar to Sun's snoop, or tcpdump) that uses the same dissection, capture-file reading and writing, and packet filtering code as Wireshark, and with editcap, which is a program to read capture files and write the packets from that capture file, possibly in a different capture file format, and with some packets possibly removed from the capture.

scapy - Scapy: the Python-based interactive packet manipulation program & library

  •    Python

Scapy is a powerful Python-based interactive packet manipulation program and library. It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, store or read them using pcap files, match requests and replies, and much more. It is designed to allow fast packet prototyping by using default values that work.

libpcap - the LIBpcap interface to various kernel packet capture mechanism

  •    C

To report a security issue please send an e-mail to security@tcpdump.org. To report bugs and other problems, contribute patches, request a feature, provide generic feedback etc please see the file CONTRIBUTING in the libpcap source tree root.

tcpdump - the TCPdump network dissector

  •    C

To report a security issue please send an e-mail to security@tcpdump.org. To report bugs and other problems, contribute patches, request a feature, provide generic feedback etc please see the file CONTRIBUTING in the tcpdump source tree root.


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.

ngrok - Introspected tunnels to localhost

  •    Go

ngrok is a reverse proxy that creates a secure tunnel between from a public endpoint to a locally running web service. ngrok captures and analyzes all traffic over the tunnel for later inspection and replay. You can give this URL to anyone to allow them to try out a web site you're developing without doing any deployment.

Bro - Network Security Monitor

  •    C++

Bro is a powerful network analysis framework that is much different from the typical intrusion detection system you may know. Bro provides a comprehensive platform for more general network traffic analysis as well.

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.

Divert - Windows Packet Divert

  •    C

Windows Packet Divert (WinDivert) is a user-mode packet interception library for Windows 7, Windows 8 and Windows 10. WinDivert enables user-mode capturing/modifying/dropping of network packets sent to/from the Windows network stack. In summary, WinDivert can Capture network packets, Filter/drop network packets, Sniff network packets, (re)inject network packets, modify network packets. It can be used to implement user-mode packet filters, sniffers, firewalls, NATs, VPNs, IDSs, tunneling applications, etc.

Zmap - The Internet Scanner

  •    C

ZMap is an open-source network scanner that enables researchers to easily perform Internet-wide network studies. With a single machine and a well provisioned network uplink, ZMap is capable of performing a complete scan of the IPv4 address space in under 45 minutes, approaching the theoretical limit of gigabit Ethernet. ZMap can be used to study protocol adoption over time, monitor service availability, and help us better understand large systems distributed across the Internet.
