Hello,
I have a tcpdump program compiled in a FreeBSD machine.  However, everytime when I start up the program, it gives me something like "Device bpf0 not config".  So, how can I config this device.  I try "MAKEDEV all" already.

You must set kernel support for bpf, which means that you'll
have to add/uncomment the following line in your kernel configuration file (usually in /usr/src/sys/i386/conf/):

pseudo-device   bpfilter        4       #Berkeley packet filter


and then recompile your kernel.
