Hello Simon,
Quite simple:
- no promisc: your NIC looks at the network, and takes only the packets
destinated to it (gets the packets where "destination MAC address" = "NIC MAC
address"),
- promisc: your NIC looks at the network, and takes ALL the packets it can get,
whether they are adressed to it or not.
So, in a nutshell:
- no promisc: your NIC shows you only your trafic
- promisc: your NIC shows you all the trafic on the wire
HTH ...

Objet : Promiscuous Mode
Hello everybody,
I have a question concerning "Promiscuous Mode", I know what it is,
but I would like to know exactly what is happening behind the scenes
when I change my NIC to this mode
For example: what is the technicality in writing the command:
ifconfig eth0 promisc?
Your help is so much appreciated.
Best regards.
