本文为大家介绍 使用arp-scan扫描局域网IP地址的方法，供大家学习参考。
1,在安装之前需要安装
yum install -y libpcap libpcap-devel
如果没有安装yum工具
需要用rpm安装如下软件包
[root@oradba arp-scan-1.8]# yum list|grep libpcap
libpcap.i386 14:0.9.4-15.el5 installed
libpcap.x86_64 14:0.9.4-15.el5 installed
libpcap-devel.i386 14:0.9.4-15.el5 installed
libpcap-devel.x86_64 14:0.9.4-15.el5 installed
2,下载软件包
wget http://www.nta-monitor.com/tools/arp-scan/download/arp-scan-1.8.tar.gz
3,编译软件包
tar xvf arp-scan-1.8.tar.gz
cd arp-scan-1.8
./configure
make && make install
查看网段所有的主机
[root@oradba arp-scan-1.8]# arp-scan -l

用于更新mac地址，便于在扫描时知道使用的是那个厂商的网卡
[root@gateway ~]# get-oui -v
