ARP Tools is collection of libnet and libpcap based ARP utilities. It currently contains:
- ARP Discover (arpdiscover), an Ethernet scanner based on ARP protocol;
- ARP Flood (arpflood), an ARP request flooder;
- ARP Poison (arppoison), for poisoning switches’ MAC address tables.
Gentoo GNU/Linux have arptools in portage as net-analyzer/arptools.

Hi, I need to restrict access to the LAN for one PC at certain times. I had hoped that I could do it with your arptools package. I have installed arptools 1.0.2 on my Fedora 8 box but I can’t find how to use arppoison properly. All I can make it do is generate random IP/MAC packets, is it possible to make it poison the switches ARP table to just prevent a single MAC address from having access?
Best regards
John.
It’s bad idea to use ARP poison to do this. I’m not even sure one can archive something similar with poisoning. You probably want to put this PC into private VLAN and try to configure forwarding policy with iptables or ebtables.
