Npcap 0.9983

Installer and debug symbols available from https://npcap.org/#download

  • Npcap can now detect newly-added network adapters without restarting the
    driver. Fixes #664.

  • Loopback capture and injection no longer requires the Npcap Loopback Adapter
    to be installed. This is a minor API change, so Nmap 7.80 and earlier will
    still require the adapter to do localhost scans, but Wireshark and most other
    software will not require changes. Loopback capture uses the device name
    NPF_Loopback instead of NPF_{GUID}, where GUID has to be looked up in
    the Registry. The Npcap Loopback Adapter can still be installed by selecting
    "Legacy loopback support" in the installer or using the
    /loopback_support=yes command-line option. TheLoopbackSupport Registry
    value will always be 0x00000001.

  • The DltNull Registry setting and the /dlt_null installer option are no
    longer supported. Loopback capture will use the DLT_NULL link type as
    described in the tcpdump
    documentation
    . Loopback packet
    injection will also use this link type instead of requiring a dummy Ethernet
    header to be constructed. The DltNull Registry value will still be present
    and set to 1 for software that consults this value.

  • Some operations like pcap_stats() can now be completed even after the
    adapter that was in use is removed. See #1650.

  • Fixed a crash that could happen when stopping the driver during a loopback
    traffic capture. Fixes #1678.
