pcap libraries windows

while libpcap developed unix-like operating systems, successful port windows made, called winpcap. winpcap has been unmaintained since 2013, , several competing forks have been released new features , support newer versions of windows.


winpcap

winpcap consists of:



x86 , x86-64 drivers windows nt family (windows nt 4.0, 2000, xp, server 2003, vista, 7, 8, , 10), use ndis 5.x read packets directly network adapter;
implementations of lower-level library listed operating systems, communicate drivers;
a port of libpcap uses api offered low-level library implementations.

programmers @ politecnico di torino wrote original code; of 2008 cace technologies, company set of winpcap developers, develops , maintains product. cace technologies acquired riverbed technology on october 21, 2010.


because winpcap uses older ndis 5.x apis, not work on builds of windows 10, have deprecated or removed apis in favor of newer ndis 6.x apis. forces limitations such being unable capture 802.1q vlan tags in ethernet headers.


npcap

npcap nmap project s packet sniffing library windows. based on winpcap / libpcap libraries, improved speed, portability, security, , efficiency. npcap offers:



ndis 6 support: npcap makes use of new ndis 6 light-weight filter (lwf) api in windows vista , later (the legacy driver used on xp). s faster deprecated ndis 5 api.
latest libpcap api support: npcap provides support latest libpcap api accepting libpcap git submodule. latest libpcap 1.8.0 has integrated more fascinating features , functions deprecated libpcap 1.0.0 shipped winpcap. moreover, since linux has support latest libpcap api, using npcap on windows facilitates software base on same api on both windows , linux.
extra security: npcap can restricted administrators can sniff packets. non-admin user have pass user account control (uac) dialog utilize driver. conceptually similar unix, root access required capture packets. driver has windows aslr , dep security features enabled.
winpcap compatibility: if selected, npcap use winpcap-style dll directories (“c:\windows\system32”) , service name (“npf”), allowing software built winpcap in mind transparently use npcap instead. if compatibility mode not selected, npcap installed in different location different service name both drivers can coexist on same system.
loopback packet capture: npcap able sniff loopback packets (transmissions between services on same machine) using windows filtering platform (wfp). after installation, npcap create adapter named npcap loopback adapter.
loopback packet injection: npcap able send loopback packets using winsock kernel (wsk) technique.
raw 802.11 packet capture: npcap able see 802.11 packets instead of fake ethernet packets on ordinary wireless adapters.

win10pcap

win10pcap implementation based on ndis 6 driver model , works stably windows 10.
