This article will explain in detail how to use the commonly used Linux command arpwatch for you. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Linux common command arpwatch command is used to monitor the record of ARP on the network. ARP (Address Resolution Protocol) is a protocol used to parse the hardware address of IP and network devices. Arpwatch can listen to and record ARP packets in the area network, and report the monitored changes through E-mail.

Syntax arpwatch [- d] [- f] [- I] [- r] parameters:

-d starts debug mode.

-f sets the file in which ARP records are stored, default to / var/arpwatch/arp.dat.

-I specifies the interface that listens to ARP, and the default interface is eth0.

-r reads the ARP record from the specified file instead of listening from the network.

-n specify additional local network

-u specify users and user groups

-e sends mail to the specified user, which is not the default root user

-s specifies the user name as the return address instead of the default user root

The instance listens to the ARP information of the Nic eth0

Arpwatch-I eth0 listens to the information of ARP and records the relevant information to the corresponding file
