Hi,

I had to replace .PL script by the .SH you provided me, but now alerts
are even more strange for me :

Entry in maclist.allow :
00:40:af:81:9a:99 192.168.0.197 rl0

Alert :
/!\ Intruder Detected /!
Intrusion time stamp : Tue Oct 6 08:21:02 CEST 2009

Intruder Ip Address : 0.0.1.104
Intruder MAC Address : 00:40:af:81:9a:99 (DIGITAL PRODUCTS, INC.)
Intruder Extra info : 192.168.0.197
Intruder Interface : rl0
Type of alert : 0

/!\ Intruder Detected /!
Intrusion time stamp : Tue Oct 6 08:29:13 CEST 2009

Intruder Ip Address : 192.168.0.197
Intruder MAC Address : 00:40:af:81:9a:99 (DIGITAL PRODUCTS, INC.)
Intruder Extra info : 0.0.1.104
Intruder Interface : rl0
Type of alert : 0

I know there is no "ip_change" option, but anyway, isn't it "strange"
alert ? I'm not sure if I understand correctly "Intruder Ip Address" and
"Intruder Extra info"...

Thank you.
