Linux Arp command harm: Linux Arp command is extremely harmful, some viruses use ARP to cheat, not only affect their own machines, but also affect other machines with the same network segment, adding virus code to the HTTP packets of other machines.

The Linux Arp command adds a trusted Windows host (192.168.1.10)

1. Operation on Linux host (192.168.1.2)

[root@ftpsvr ~] # echo '192.168.1.10 00 etc/ip-mac 04 etc/ip-mac 61R AEV 09R 14' >

[root@ftpsvr] # arp-f / etc/ip-mac

2. Linux Arp commands to operate on the Windows host (192.168.1.10)

1) clear the ARP cache

C:Documents and SettingsAdministrator > arp-d

2) the Linux Arp command binds the IP and MAC addresses of Linux hosts

C:Documents and SettingsAdministrator > arp-s 192.168.1.2 00-04-61-9A-8D-B2

You can write the above two steps in a BAT (batch) file. The advantage of this is that if you want to add bindings to other machines in the future, you only need to maintain this file. Example:

@ echo off

Arp-d

Arp-s 192.168.1.200-04-61-9A-8D-B2

Exit

Note: the MAC address format on Linux and Widows is different. Linux is expressed as: AA:AA:AA:AA:AA:AA,Windows is expressed as: AA-AA-AA-AA-AA-AA
