This module is a unified framework to craft, send and receive packets at layers 2, 3, 4 and 7. Basically, you forge each layer of a frame (Net::Packet::IPv4 for layer 3, Net::Packet::TCP for layer 4 ; for example), and pack all of this into a Net::Packet::Frame object. Then, you can send the frame to the network, and receive it easily, since the response is automatically searched for and matched against the request.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
