	Dear sirs,

	I have the following problem: I would like to use tcpdump on my FreeBSD
3.2 release. When I type the shell command "tcpdump", the following
message appears:

	tcpdump: /dev/bpf0: Device not configured

	I have looked at the tcpdump man page, and it talks about the fact that
I must have read access on /dev/bpf0 in order to work properly with
tcpdump.

	How can I do this?

	Many thanks,

						Carles Gómez Montenegro
