arp: arp相关的命令
目录
ip neigh
arp命令已经不推荐使用，推荐使用ip neigh
arp - 管理本地的arp记录
arp - manipulate the system ARP cache
Arp manipulates or displays the kernel's IPv4 network neighbour cache. It can add entries to the table, delete one or display the current content.
This program is obsolete. For replacement check ip neigh. (man 8 ip-neighbour)
手册：
man 8 arp
查看arp entry：
arp [-vn] [-H type] [-i if] [-ae] [hostname]
-v: verbose
-n: shows numerical addresses
-H: 过滤条件，arp entry类型, 默认为"ether",
可用类型有： ARCnet (arcnet) , PROnet (pronet) , AX.25 (ax25) and NET/ROM (netrom) ...
-i: 过滤条件，arp entry所在的网口
-a: 显示格式，Use alternate BSD style output format (with no fixed columns).
-e: 显示格式，Use default Linux style output format (with fixed columns).
hostname: 过滤条件，查看该IP地址或主机名的arp entry
查看所有arp entry
[root@localhost ~]# arp
Address HWtype HWaddress Flags Mask Iface
localhost ether 00:0c:29:81:35:6c C eno50332208
localhost ether 00:50:56:fa:26:95 C eno33554984
localhost ether 00:50:56:c0:00:01 C eno33554984

localhost ether 00:50:56:f3:1f:8b C eno16777736
localhost ether 00:50:56:fd:02:ef C eno16777736
Flags Mask说明:
C: complete entry
M: permanent entry
P: published entry
查看指定主机的的arp entry
[root@localhost ~]# arp -n 10.10.64.151
Address HWtype HWaddress Flags Mask Iface
10.10.64.151 ether 00:0c:29:81:35:6c C eno50332208
查看指定网口上的arp entry
[root@localhost ~]# arp -n -i eno50332208
Address HWtype HWaddress Flags Mask Iface
10.10.64.151 ether 00:0c:29:81:35:6c C eno50332208
10.10.64.192 ether 00:0c:29:81:35:6c CM eno50332208
删除arp entry:
arp [-v] [-i if] -d hostname [pub]
-v: verbose
-i: 过滤条件，指定网口
-d: 删除模式, 删除arp entry
pub: 过滤条件，arp entry具有pub标记
具有pub标记的arp entry是代理arp
添加arp entry:
arp [-v] [-H type] [-i if] -s hostname hw_addr [temp]
arp [-v] [-H type] [-i if] -s hostname hw_addr [netmask nm] pub
arp [-v] [-H type] [-i if] -Ds hostname ifname [netmask nm] pub
arp [-vnD] [-H type] [-i if] -f [filename]
-v: verbose
-H: arp entry类型,可用类型有： IEEE 802.3(ether), ARCnet (arcnet) , PROnet (pronet) , AX.25 (ax25) and NET/ROM (netrom) ...
-i: 所属的网口
-s: 添加模式，增加arp entry
hostname: arp entry的IP
hw_addr: arp entry的mac地址
temp: arp entry标记，临时arp, 如果么有指定temp, arp entry将一直保存
pub: arp entry标记，代理arp
netmask: 代理arp作用的网段
-D: 使用指定网口的MAC地址作为hw_addr
-f: 从文件中读取要设置的arp条目, 文件中每行记录的格式： hostname hw_addr [temp|netmask nm pub]
arping - 发送arp请求
arping - send ARP REQUEST to a neighbour host
arping [-AbDfhqUV] [-c count] [-w deadline] [-s source] [-I interface] destination
Ping destination on device interface by ARP packets, using source address sourc
示例:
arping -I eth1 192.168.40.1
ARPING 192.168.40.1 from 192.168.40.2 eth1
