Thanks for your reply!

I want to know in what situations the machine's
network is set to "promiscuous" mode. For example,
I
know when I execute "tcpdump" on my machine, it's
set
to be in promiscuous mode. Any other cases?
 

Yes, that's program's that decide to put your NIC
into promicious mode.

And is it correct that without "tcpcump", the
network
is not in promiscuous mode?
 

Depend's on what programs are running on your box.
Under linux you can watch to you /var/log/messages
to see
kernel messages show you when your box enter, or
leave promicious
mode.

Thanks.
