You are correct. Only its own traffic, but don't forget about
broadcasts! If a switch is involved, broadcasts from other machines on the
same network/vlan/subnet still come across all ports but the one it came in
on.

There is really no way (that I know of) to detect if a device is listening
to the network in promiscuous mode.
If users have sufficient control of their machines to set the network port
to promiscuous mode, then:
If they are connected to the network using hubs, there is no way to stop
them
from listening to traffic.
If they are connected to the network using switches, and they do not have
the capability
of setting the switch to pass all traffic to their switch port, they will
only be able
to capture their own network traffic.

Hello, ethereal-users,
If I have suspected that someone in my LAN has installed Ethereal on his/her
PC. How do I block Ethereal from monitoring my LAN traffic? Thank you.
Best regards.
