arping 报错

标签：broadcast   网络   网卡   linux   

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。

[root@localhost etc]# arping 10.2.167.27
arping: unknown iface eth0
[root@localhost etc]# arping  10.2.167.177
arping: unknown iface eth0
[root@localhost etc]# 

ifconfig看一下。

[root@localhost etc]# ifconfig 
eth1      Link encap:Ethernet  HWaddr 00:0C:29:D8:3D:17  
          inet addr:10.2.167.27  Bcast:10.2.167.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:fed8:3d17/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:479073 errors:0 dropped:0 overruns:0 frame:0
          TX packets:17498 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:73918361 (70.4 MiB)  TX bytes:3437224 (3.2 MiB)
          Interrupt:19 Base address:0x2024 

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:5932 errors:0 dropped:0 overruns:0 frame:0
          TX packets:5932 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:372219 (363.4 KiB)  TX bytes:372219 (363.4 KiB)

那么就换个出口。用I可以指定出口网卡。

[root@localhost etc]# arping -I eth1 10.2.167.177
ARPING 10.2.167.177 from 10.2.167.27 eth1
