nu_plugin_pnet

This is taken from https://github.com/fennewald/nu_plugin_net and modernized a tiny bit. Thanks! Be sure to read the changelog for tips for Windows users.

A nushell plugin to list system network interfaces

A simple and straightforward plugin. All of the heavy lifting is done by pnet. This package just translates the datatypes into a nu-accepatble format.

Format may be subject to change.

Installing

This plugin uses the msgpack encoding. To register:

register <path to plugin binary>

Changelog

Version 1.1.0

Use if_index instead of index, fixing the way table indexes are displayed

Version 1.2.0

Renamed from net to pnet as to not cause a conflict on Windows.

The biggest mistake I made was not realizing that:

1. You have to download Packet.lib from Winpcap Developers Pack from https://www.winpcap.org/devel.htm, making sure to use the x64 version vs the x86 version. You have to put Packet.lib in the root of the nu_plugin_pnet folder for linking.
2. You have to install npcap installer from https://npcap.com/#download

Otherwise you get these errors when trying to register

register c:\CarTar\debug\nu_plugin_pnet.exe
  × Error getting signatures
