arpalert is used for monitoring networks. It listens on a network interface (without using 'promiscuous' mode) and catches all conversations of MAC address to IP request.

arpalert 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.

This software can run in deamon mode; it's very fast (low CPU and memory consumption).

It responds at signal SIGHUP (configuration reload) and at signals SIGTERM, SIGINT, SIGQUIT and SIGABRT (arpalert stops itself)

What's New in This Release:
Corrections were made in the man page.
arpalert doesn't quit if the leases file is not found at start, it just sends a notice.
Variable type was corrected.
Alert identifiers were defined.
A MAC address without an IP address is now also put in the leases file.
