简介

一款局域网地址冲突检测的命令行工具，能检测出局域网不同设备之间IP和MAC地址冲突

用法

# 安装
cargo install --git https://github.com/lbhzy/lan-acd

# 使用说明
$ lan-acd -h
LAN address conflict detection (2025-01-22 23:48:07 +08:00)

Usage: lan-acd.exe [OPTIONS]

Options:
  -l, --list               List all interfaces and index
  -i, --iface <IFACE>      Select interface index
  -t, --timeout <TIMEOUT>  Stop if no ARP reply beyond this time (ms) [default: 300]
  -h, --help               Print help

# 查看网络接口
$ lan-acd -l

局限

由于Windows系统不会响应以太网头中源Mac地址与自身冲突的ARP请求，因此，无法检测到本机与其他Windows主机之间Mac冲突的情况
