strives to provide most of GNU grep's common features, applying them to the network layer. ngrep is a pcap-aware tool that will allow you to specify extended regular or hexadecimal expressions to match against data payloads of packets. It currently recognizes TCP, UDP and ICMP across Ethernet, PPP, SLIP, FDDI, Token Ring and null interfaces, and understands bpf filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.

clj-net-pcap is a packet capturing library for Clojure. clj-net-pcap uses jNetPcap and adds convenience functionality around jNetPcap for easing the usability. A paper on clj-net-pcap was published in scope of COMPSACW 2014.

OpenFPC is a set of scripts that combine to provide a lightweight full-packet network traffic recorder & buffering tool. Its design goal is to allow non-expert users to deploy a distributed network traffic recorder on COTS hardware while integrating into existing alert and log tools.

PCAPdroid is an Android app which lets you monitor and export the network traffic of your device without root. Traffic can be dumped in the PCAP format to be analyzed with popular tools like Wireshark, even in real time. The built-in traffic monitor lets you detect suspicious connections made by user and system apps.

A multi-threading tool to sniff TCP flow statistics and embedded HTTP headers from PCAP file. Each TCP flow carrying HTTP is exported to text file in JSON format.

summarizes TCP/IP dump files into a self-describing ASCII format easily readable by humans and programs. Ipsumdump can read packets from network interfaces, from tcpdump files, and from existing ipsumdump files. It will transparently uncompress tcpdump or ipsumdump files when necessary. It can randomly sample traffic, filter traffic based on its contents, anonymize IP addresses, and sort packets from multiple dumps by timestamp. Also, it can optionally create a tcpdump file containing actual packet data. It's also convenient to work with CLICK as a inserted module.

It aims to be the fundamental high-level building block for doing practical, real world network data analysis in Python. Additionally, it has the broader goal of becoming a common network data analytics framework for researchers providing data reproducibility across experiments.

PcapPlusPlus a multiplatform C++ network sniffing and packet parsing and manipulation framework. It's meant to be lightweight, efficient and easy to use. It's a C++ wrapper for popular engines like libpcap, WinPcap, DPDK and PF_RING. It also contains parsing and edit capabilities for many protocols including Ethernet, IPv4, IPv6, ARP, VLAN, MPLS, PPPoE, GRE, TCP, UDP, ICMP, DNS as well as layer 7 protocols like HTTP and SSL/TLS

pcaptoparquet is a Python package designed for converting PCAP or PCAPNG files to structured data formats, primarily Apache Parquet. The tool focuses on network traffic analysis by extracting, decoding, and transforming packet data into queryable datasets suitable for analysis and visualization. The tool supports both command-line and programmatic interfaces, enabling integration into various network analysis workflows.

A simple utility to classify packets into flows. It's so simple that only one task is aimed to finish. For Deep Packet Inspection or flow classification, it's so common to analyze the feature of one specific flow. I have make the attempt to use made-ready tools like tcpflows, tcpslice, tcpsplit, but all these tools try to either decrease the trace volume (under requirement) or resemble the packets into flow payloads (over requirement). I have not found a simple tool to classify the packets into flows without further processing.

Normalizes, indexes, enriches and visualizes network captures.

A Python wrapper for tshark, allowing python packet parsing using wireshark dissectors. There are quite a few python packet parsing modules, this one is different because it doesn't actually parse any packets, it simply uses tshark's (wireshark command-line utility) ability to export XMLs to use its parsing.

A tool written by Shawn Ostermann at Ohio University, for analysis of TCP dump files. It can take as input the files produced by several popular packet-capture programs, including tcpdump, snoop, etherpeek, HP Net Metrix, and WinDump. 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, throughput, and more. It can also produce a number of graphs for further analysis.

Replays a pcap file on an interface using libnet.

Tcpslice is a tool for extracting portions of packet trace files generated using tcpdump's -w flag. It can combine multiple trace files, and/or extract portions of one or more traces based on time.

A tool to break a single libpcap packet trace into some number of sub- traces, breaking the trace along TCP connection boundaries so that a TCP connection doesn't end up split across two sub-traces. This is useful for making large trace files tractable for in- depth analysis and for subsetting a trace for developing analysis on only part of a trace.

TraceWrangler is a network capture file toolkit running on Windows (or on Linux, using WINE) that supports PCAP as well as the new PCAPng file format, which is now the standard file format used by Wireshark. The most prominent use case for TraceWrangler is the easy sanitization and anonymization of PCAP and PCAPng files (sometimes called "trace files", "capture files" or "packet captures"), removing or replacing sensitive data while being easy to use.

is a Windows library for user-mode packet interception.

A program to convert .pcap network capture files to HTTP Archive files using library dpkt.

A freeware tool to trace TCP/UDP/... sessions and fetch application data from snoop or tcpdump logs. This is a type of "any-snarf" program, as it will fetch telnet sessions, FTP files, HTTP transfers (HTML, GIF, JPEG, ...), SMTP emails, ... from the captured data inside network traffic logs. A html index file is created that links to all the session details, including realtime replay programs for telnet, rlogin, IRC, X11 and VNC sessions; and reports such as image reports and HTTP GET/POST content reports.

is a console program to recover files based on their headers, footers, and internal data structures. This process is commonly referred to as data carving. Foremost can work on image files, such as those generated by dd, Safeback, Encase, etc, or directly on a drive. The headers and footers can be specified by a configuration file or you can use command line switches to specify built-in file types. These built-in types look at the data structures of a given file format allowing for a more reliable and faster recovery.

Packet CAPture Forensic Evidence eXtractor (pcapfex) is a tool that finds and extracts files from packet capture files. Its power lies in its ease of use. Just provide it a pcap file, and it will try to extract all of the files. It is an extensible platform, so additional file types to recognize and extract can be added easily.
