does snoop work in promiscuous mode?

Hi,
   Ok changed the rights on the file

crw-rw-rw-   1 root     sys       11, 80 May 14  2006 clone@0:ce

but this still does not make a difference. I did not restart the system.
Just changed rights and made trace which did not work.

I used to capture promiscous on sun boxen without any problem.

So it might be an issue with permissions of the /dev/ node for the
interface which I remember I had to change myself.
.
Can you capture as root?
If so which are the permissions on /dev/ifname?
What happens if you change permissions on /dev/ifname so that it is
writable by the user, can you capture promiscuous then?
