怎样快速扫描到上游局域网中的设备

萝卜大侠

很多时候我们需要快速知道上游局域网中存在哪些设备，IP地址是否冲突
很多扫描工具都可以达到这一目的，比如nmap,arp-scan等，我实际测试，效率最高的还是arp-scan,下面是安装步骤及使用方法

安装

1. opkg update
   
2. opkg install arp-scan

复制代码

使用

1. root@GL-AXT1800:~#arp-scan -I eth0 192.168.99.0/24
   
2. Interface: eth0, type: EN10MB, MAC: 94:83:c4:17:06:1a, IPv4: 192.168.99.218
   
3. WARNING: Cannot open MAC/Vendor file /usr/share/arp-scan/ieee-oui.txt: No such file or directory
