How to realize batch processing to prevent arp virus

This article mainly introduces how to achieve batch processing to prevent arp virus, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

The code is as follows:

@ echo off

:::

Native and gateway IP and MAC address binding batch programs:

:::

Arp-d

Read native Mac address

If exist ipconfig.txt del ipconfig.txt

Ipconfig / all > ipconfig.txt

If exist phyaddr.txt del phyaddr.txt

Find "Physical Address" ipconfig.txt > phyaddr.txt

For / f "skip=2 tokens=12"% M in (phyaddr.txt) do set Mac=%%M

Read native ip address

If exist IPAddr.txt del IPaddr.txt

Find "IP Address" ipconfig.txt > IPAddr.txt

For / f "skip=2 tokens=15"% I in (IPAddr.txt) do set IP=%%I

Bind native IP address and MAC address

Arp-s% IP%% Mac%

Read gateway address

If exist GateIP.txt del GateIP.txt

Find "Default Gateway" ipconfig.txt > GateIP.txt

For / f "skip=2 tokens=13" G in (GateIP.txt) do set GateIP=%%G

: get the gateway MAC address

Ping 192.168.0.1-n 1

Read gateway Mac address

If exist GateMac.txt del GateMac.txt

Arp-a% GateIP% > GateMac.txt

For / f "skip=3 tokens=2"% H in (GateMac.txt) do set GateMac=%%H

Bind gateways Mac and IP

Arp-s% GateIP%% GateMac%

Del GateIP.txt

Del GateMac.txt

Del IPAddr.txt

Del ipconfig.txt

Del phyaddr.txt

Exit
