arping命令是获取同一个网络下面主机的mac地址。这里的同一网络是ip可以互通。linux下面。
可以知道这个ip是否被占用，一个很有用的命令。刚才操作了一下报错。
[[email protected] etc]# arping 10.2.167.27 arping: unknown iface eth0 [[email protected] etc]# arping 10.2.167.177 arping: unknown iface eth0 [[email protected] etc]#
很郁闷怎么报错呢，原来是没有eth0网卡。它默认从网卡0出。
ifconfig看一下。
[[email protected] etc]# ifconfig

真的没有网卡0.
那么就换个出口。用I可以指定出口网卡。
