Re: The device eth0 has entered in promiscous mode

hi,

at first you should know what does it mean :

http://en.wikipedia.org/wiki/Promiscuous_mode

if you use for example arpwatch the NIC will go to the promiscous mode, because you need to sniff all arp request, this is for example.

it simply means eth0 will accept all packets on the network.

you can turn it off by issuing
ifconfig eth0 -promisc
