Mac下扫描局域网主机信息

1、安装nmap

brew install nmap

2、扫描局域网主机(如192.168.0.0网段)

sudo nmap -sn 192.168.0.0/24

或者使用 sudo nmap -A 192.168.1.0/24 命令参数扫描!(缺点:扫描速度较慢)

Starting Nmap 7.98 ( https://nmap.org ) at 2025-11-13 10:49 +0800

4、重点扫描某台电脑

sudo nmap -Pn -sS --open -T4 192.168.0.254

5、分析端口

Nmap scan report for 192.168.0.254

备注:

有时候sudo nmap -sn 192.168.1.0/24 执行一遍,扫描不完整,可以多执行几遍,确保扫描的完整性.
