Live Capture

Netcap can also capture traffic directly from your network interface.

On macOS and windows this makes use of C bindings to libpcap fetch the packets from the interface, on Linux there is a pure Go implementation available.

Use the net.capture tool to attach to a network interface and extract audit records.
