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 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
