libncap-dev - 1.9.2-7 main

ncap is a network capture library like libpcap (on which it is based)
and tcpdump. It produces binary data in its own ncap format, which can
be stored in a dump file or transmitted over a UDP socket. Unlike
libpcap, it discards data link headers and only supports IPv4 and IPv6
packets, but it can perform reassembly of IP datagrams.
.
This package contains the static library, development headers, and
documentation.
