monitor ARP changes in ethernet networks
DescriptionThe arpalert daemon is a security tool that listens on a network interface (without using 'promiscuous' mode) and catches all conversations of MAC address to IP request to alert of possibility of ARP spoofing attack. It compares the mac addresses it detected with a pre-configured list of authorized MAC addresses. If the MAC is not in list, arpalert launches a pre-defined user script with the MAC address and IP address as parameters. If you need to use a list of authorized MAC addresses, this package should suit your needs, otherwise arpwatch may be also fine.
