Linux 绑定ARP-爱开源

假如 192.168.1.1 是我的网关

[root@localhost ~]# ping 192.168.1.1

[root@localhost ~]# arp
Address HWtype HWaddress Flags Mask Iface
192.168.1.1 ether 00:19:E0:F4:30:2A C eth0

网关的MAC 00:19:E0:F4:30:2A
Flags Mask C (表示为静态)

[root@localhost ~]# echo “192.168.1.1 00:19:E0:F4:30:2A” >/etc/ethers

把网关IP和MAC地址写入到 /etc/ethers

[root@localhost ~]# arp -f

[root@localhost ~]# arp
Address HWtype HWaddress Flags Mask Iface
192.168.1.1 ether 00:19:E0:F4:30:2A CM eth0

Flags Mask为 CM (静态网关表示绑定成功)
