...or "/dev/bpf*", if there's more than 10 BPF devices (there probably 
won't be, but...).

That command allows everybody to capture.  If you only want yourself to 
be able to capture, do

	sudo chown {your login name} /dev/bpf*

and if you want, for example, everybody with administrative access to be 
able to capture, do

	sudo chgrp admin /dev/bpf*
	sudo chmod g+r /dev/bpf*

Or install the ChmodBPF startup item from the current top-of-tree CVS 
version of libpcap, which will do it after each restart for you.
