ipsentinel

ipsentinel tries to prevent unauthorized usage of IPs within the local
ethernet broadcast domain by giving an answer to ARP-requests. After
receiving such a faked reply, the requesting party stores the told MAC
in its ARP-table and will send future packets to this MAC. Because
this MAC is invalid, the host with the invalid IP can not be reached.

Features

 - non-root execution in a chroot jail
 - freely customizable IPs (netmasks, negations, ranges)
