can you send me your config file and your arpalert version ?

the authorisation is a list of ip addresses can be requested by a mac
adress. in the exemple, the host with the mac address "01:02:03:04:05:06"
can be send arp request for ip 10.0.0.1 and 10.0.0.2.

if arpalert watch arp request from the mac address "01:02:03:04:05:06" and
the ip requested is 10.6.7.8, it can be send alert.

Thierry
