如何在Linux中发现IP地址冲突
你们都知道什么是IP地址，是吧？它们被分配给网络上的设备来代表它们。它们通过DHCP服务器分配并且会经常改变。现在有两种IP地址。动态的一种会经常改变（几天一次），而静态的就如它的名字那样是静态的，意味着它们不会改变。
有时这会引发一些冲突。当一个动态IP被分配了并且有另外一台网络设备已经拥有了相同的IP。或者在相同网络子网上有多台分配IP的DHCP服务器。如果你有连通问题并且假设它是由于IP冲突造成的，那么你可以使用一个工具称作arp-scan来扫描它们。
这个工具会在本地网络发送ARP（Address Resolution Protocol）(地址解析协议)包来收集地址。如果有多个MAC地址声称拥有相同的IP地址，那么这里就存在冲突。
要在Ubuntu或者Debian上安装arp-scan则输入：
$ sudo apt-get install arp-scan
对于Fedora，CentOS或者RedHat：
$ sudo yum install arp-scan
要检测IP冲突，运行下面的命令:
$ sudo arp-scan –I eth0 -l
输出示例：
192.168.1.10 00:1b:a9:63:a2:4c BROTHER INDUSTRIES, LTD.
192.168.1.30 00:1e:8f:58:ec:49 CANON INC.
192.168.1.33 00:25:4b:1b:10:20 Apple, Inc
192.168.1.37 10:9a:dd:55:d7:95 Apple Inc
192.168.1.38 20:c9:d0:27:8d:56 (Unknown)
192.168.1.39 d4:85:64:4d:35:be Hewlett Packard
192.168.1.39 00:0b:46:e4:8e:6d Cisco (DUP: 2)
192.168.1.40 90:2b:34:18:59:c0 (Unknown)
在本例中，192.168.1.39这个IP冲突了，因为它出现了两次。
