防arp（转oneleaf 老大的）
引用:
1) 建立静态ARP表
touch /etc/static_arp_entry
chown root:root /etc/static_arp_entry
chmod 600 /etc/static_arp_entry
2) 编辑/etc/static_arp_entry文件，输入类似内容
192.168.8.90 00:00:00:11:11:11
192.168.8.1 00:00:00:22:22:22
3) arp -s -f /etc/static_arp_entry
我是直接加入两行命令到/etc/init.d/rc.local中
原理是每次系统启动时自动绑定网关IP和MAC
然后禁用ARP协议，这样就OK了！~！~
pjq@pjq-desktop:~$ cat /etc/init.d/rc.local
