Wireshark - Network Traffic Analyzer

  •        81

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.

Its features include:

  • Deep inspection of hundreds of protocols, with more being added all the time
  • Live capture and offline analysis
  • Standard three-pane packet browser
  • Multi-platform: Runs on Windows, Linux, macOS, Solaris, FreeBSD, NetBSD, and many others
  • Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility
  • The most powerful display filters in the industry
  • Rich VoIP analysis
  • Read/write many different capture file formats: tcpdump (libpcap), Pcap NG, Catapult DCT2000, Cisco Secure IDS iplog, Microsoft Network Monitor, Network General Sniffer® (compressed and uncompressed), Sniffer® Pro, and NetXray®, Network Instruments Observer, NetScreen snoop, Novell LANalyzer, RADCOM WAN/LAN Analyzer, Shomiti/Finisar Surveyor, Tektronix K12xx, Visual Networks Visual UpTime, WildPackets EtherPeek/TokenPeek/AiroPeek, and many others
  • Capture files compressed with gzip can be decompressed on the fly
  • Live data can be read from Ethernet, IEEE 802.11, PPP/HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI, and others (depending on your platform)
  • Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2
  • Coloring rules can be applied to the packet list for quick, intuitive analysis
  • Output can be exported to XML, PostScript®, CSV, or plain text

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.

tcpreplay - Pcap editing and replay tools for *NIX and Windows - Users please download source from

  •    C

Tcpreplay is a suite of GPLv3 licensed utilities for UNIX (and Win32 under Cygwin) operating systems for editing and replaying network traffic which was previously captured by tools like tcpdump and Ethereal/Wireshark. It allows you to classify traffic as client or server, rewrite Layer 2, 3 and 4 packets and finally replay the traffic back onto the network and through other devices such as switches, routers, firewalls, NIDS and IPS's. Tcpreplay supports both single and dual NIC modes for testing both sniffing and in-line devices.Tcpreplay is used by numerous firewall, IDS, IPS, NetFlow and other networking vendors, enterprises, universities, labs and open source projects. If your organization uses Tcpreplay, please let us know who you are and what you use it for so that I can continue to add features which are useful.

Joy is a BSD-licensed libpcap-based software package for extracting data features from live network traffic or packet capture (pcap) files, using a flow-oriented model similar to that of IPFIX or Netflow, and then representing these data features in JSON. It also contains analysis tools that can be applied to these data files. Joy can be used to explore data at scale, especially security and threat-relevant data. JSON is used in order to make the output easily consumable by data analysis tools. While the JSON output files are somewhat verbose, they are reasonably small, and they respond well to compression.
