I need help using tcpdump on FreeBSD 2.1.5.  Every time I run it, it get 
a message about /dev/bpf0 not being configured.  I cannot find any info 
on configuring bpf.  The man page has programming info, but I couldn't 
find anything re: configuring.

Am I expected to write a program myself?  I haven't had to do this on 
other unixes I've used.  For example pfconfig(8) on Digital Unix allows
me to config the packet filter driver.

Note:  I did not build the kernel (no disk space yet).  I am using what 
I installed of the CD which arrived a few days ago.

Thanks for any info.
Mike
