sto testando arpwatch per rilevare arp-poisoning su una Wireless lan.

ho incontrato alcuni problemi ai quali non riesco a venire a capo un pò perchè sono scarso è un pò perche proprio non trovo nessun aiuto in giro.

ho installato arpwatch senza problemi

la mia lan è sulla 192.168.3.xx e ho configurato il .conf così:

Code:
# /etc/arpwatch.conf: Debian-specific way to watch multiple interfaces.
# Format of this configuration file is:
#
#<dev1> <arpwatch options for dev1>
#<dev2> <arpwatch options for dev2>
#...
#<devN> <arpwatch options for devN>
#
# You can set global options for all interfaces by editing
# /etc/default/arpwatch

#eth0   -m root+eth0
#eth1   -m root+eth1

wlan0 -a -n 192.168.3.0/24 -m mioindirizzo@gmail.com
guardando il syslog arpwatch sembra funzionare ma produce errori che non capisco:

Code:
root@bt:/etc# less /var/log/syslog |grep arpwatch

inoltre, di mail neanche un ombra, perchè (e qui entra in gioco la mia scarsità) non ho idea di come si configuri sendmail su BT , anche cercando qui su sito e forum non mi pare ci sia una guida, utilizzando sendmailconfig si configura soltanto con il conf presente e non con l'opzione manuale.

Qualche aiuto?
