Wireshark is the world's foremost network protocol analyzer, and is the de facto (and often de jure) standard across many industries and educational institutions. Wireshark development thrives thanks to the contributions of networking experts across the globe. It is the continuation of a project that started in 1998.

What do you need to know about free software?

In the field of computernetwork administration, pcap is an application programming interface (API) for capturing network traffic. While the name is an abbreviation of the technical term of art (jargon) packet capture, that is not the API's proper name. Unix-like systems implement pcap in the libpcap library; for Windows, there is a port of libpcap named WinPcap that is no longer supported or developed, and a port named Npcap for Windows 7 and later that is still supported.

Monitoring software may use libpcap, WinPcap, or Npcap to capture network packets travelling over a computer network and, in newer versions, to transmit packets on a network at the link layer, and to get a list of network interfaces for possible use with libpcap, WinPcap, or Npcap.

The pcap API is written in C, so other languages such as Java, .NET languages, and scripting languages generally use a wrapper; no such wrappers are provided by libpcap or WinPcap itself. C++ programs may link directly to the C API or use an object-oriented wrapper.

Features[edit]

libpcap, WinPcap, and Npcap provide the packet-capture and filtering engines of many open-source and commercial network tools, including protocol analyzers (packet sniffers), network monitors, network intrusion detection systems, traffic-generators and network-testers.

libpcap, WinPcap, and Npcap also support saving captured packets to a file, and reading files containing saved packets; applications can be written, using libpcap, WinPcap, or Npcap, to be able to capture network traffic and analyze it, or to read a saved capture and analyze it, using the same analysis code. A capture file saved in the format that libpcap, WinPcap, and Npcap use can be read by applications that understand that format, such as tcpdump, Wireshark, CANetMaster, or Microsoft Network Monitor 3.x.

The MIME type for the file format created and read by libpcap, WinPcap, and Npcap is application/vnd.tcpdump.pcap. The typical file extension is .pcap, although .cap and .dmp are also in common use.^[4]

History[edit]

libpcap was originally developed by the tcpdump developers in the Network Research Group at Lawrence Berkeley Laboratory. The low-level packet capture, capture file reading, and capture file writing code of tcpdump was extracted and made into a library, with which tcpdump was linked.^[5] It is now developed by the same tcpdump.org group that develops tcpdump.^[6]

pcap libraries for Windows[edit]

While libpcap was originally developed for Unix-like operating systems, a successful port for Windows was made, called WinPcap. It has been unmaintained since 2013,^[7] and several competing forks have been released with new features and support for newer versions of Windows.

WinPcap[edit]

WinPcap consists of:^[8]

• x86 and x86-64 drivers for the Windows NT family (Windows NT 4.0, 2000, XP, Server 2003, Vista, 7, 8, and 10), which use Network Driver Interface Specification (NDIS) 5.x to read packets directly from a network adapter;
• implementations of a lower-level library for the listed operating systems, to communicate with those drivers;
• a port of libpcap that uses the API offered by the low-level library implementations.

Programmers at the Politecnico di Torino wrote the original code; as of 2008 CACE Technologies, a company set up by some of the WinPcap developers, developed and maintained the product. CACE was acquired by Riverbed Technology on October 21, 2010.^[9]

Because WinPcap uses the older NDIS 5.x APIs, it does not work on some builds of Windows 10, which have deprecated or removed those APIs in favor of the newer NDIS 6.x APIs. It also forces some limitations such as being unable to capture 802.1Q VLAN tags in Ethernet headers.

Npcap[edit]

Npcap is the Nmap Project's packet sniffing library for Windows.^[10] It is based on the Winpcap / Libpcap libraries, but with improved speed, portability, security, and efficiency.Npcap offers:

• NDIS 6 Support: Npcap makes use of new NDIS 6 Light-Weight Filter (LWF) API in Windows Vista and later (the legacy driver is used on XP). It's faster than the deprecated NDIS 5 API.
• Latest libpcap API Support: Npcap provides support for the latest libpcap API by accepting libpcap as a Git submodule. The latest libpcap 1.8.0 has integrated more fascinating features and functions than the deprecated libpcap 1.0.0 shipped by WinPcap. Moreover, since Linux already has a good support for latest libpcap API, using Npcap on Windows facilitates software to base on the same API on both Windows and Linux.
• Extra Security: Npcap can be restricted so that only Administrators can sniff packets. Non-Admin user will have to pass a User Account Control (UAC) dialog to utilize the driver. This is conceptually similar to UNIX, where root access is generally required to capture packets. The driver also has Windows ASLR and DEP security features enabled.
• WinPcap compatibility: If selected, Npcap will use the WinPcap-style DLL directories (“c:WindowsSystem32”) and service name (“npf”), allowing software built with WinPcap in mind to transparently use Npcap instead. If compatibility mode is not selected, Npcap is installed in a different location with a different service name so that both drivers can coexist on the same system.
• Loopback Packet Capture: Npcap is able to sniff loopback packets (transmissions between services on the same machine) by using the Windows Filtering Platform (WFP). After installation, Npcap will create an adapter named Npcap Loopback Adapter.
• Loopback Packet Injection: Npcap is also able to send loopback packets using the Winsock Kernel (WSK) technique.
• Raw 802.11 Packet Capture: Npcap is able to see 802.11 packets instead of fake Ethernet packets on ordinary wireless adapters.

Win10Pcap[edit]

Win10Pcap implementation is also based on the NDIS 6 driver model and works stably with Windows 10.^[11]
