CACE was acquired by Riverbed Technology on October 21, 2010. 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. a port of libpcap that uses the API offered by the low-level library implementations.implementations of a lower-level library for the listed operating systems, to communicate with those drivers.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.It has been unmaintained since 2013, and several competing forks have been released with new features and support for newer versions of Windows. While libpcap was originally developed for Unix-like operating systems, a successful port for Windows was made, called WinPcap. It is now developed by the same group that develops tcpdump. 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. Libpcap was originally developed by the tcpdump developers in the Network Research Group at Lawrence Berkeley Laboratory. The MIME type for the file format created and read by libpcap, WinPcap, and Npcap is application/. 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, CA NetMaster, or Microsoft Network Monitor 3.x. 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. 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. C++ programs may link directly to the C API or make use of an object-oriented wrapper. NET languages, and scripting languages generally use a wrapper no such wrappers are provided by libpcap or WinPcap itself. The pcap API is written in C, so other languages such as Java. Monitoring software may use libpcap, WinPcap, or Npcap to capture network packets traveling 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. 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. While the name is an abbreviation of packet capture, that is not the API's proper name. In the field of computer network administration, pcap is an application programming interface (API) for capturing network traffic.

Ready to give Npcap a try? Just download the latest installer. Npcap is WinPcap for modern Windows systemsīuilt on the tried-and-true WinPcap codebase, with a host of exciting newįeatures, and extensively tested with currently-supported versions of Windows, Npcap is under active development and continues to support the latest Windows networking features. Npcap is fully compliant, with its drivers tested and co-signed by Windalso introduced strict driver-signing requirements that WinPcapĬan't meet. Fortunately, the Nmap Project stepped upĪnd created Npcap, converting the original WinPcap code to the new NDIS 6 API, giving users a fastĪnd completely compatible alternative to WinPcap for Windows 10. Windows 10 was released without NDIS 5 support, WinPcap failed to keep up, For 14 years, WinPcap was the standard libpcap package for Windows.
