Running ethereal on FBSD

[David Fleck]

I'm trying to get ethereal running on my 4.6.2-RELEASE system.
When I try to find out what interfaces it can capture data from, I get
this:

dcf>$ tethereal -D
tethereal: There are no interfaces on which a capture can be done

I've tried as root, same response.

Now, the network's up and running when I do this- as far as I know, the
interfaces are configured and running properly.  There's obviously some
basic thing I'm missing here, but I've gone through the man page and the
Users' Guide and am still at a loss.
Why can't I do a capture from my ethernet card (using dc0 as the
interface)?
What can I do about it?

Thanks in advance-
