Why do I get ``/dev/bpf0: device not configured''?

You are running a program that requires the Berkeley Packet Filter ( bpf(4)), but it's not in your kernel. Add this to your kernel config file and build a new kernel:

    pseudo-device bpf        # Berkeley Packet Filter

After rebooting, create the device node. This can be accomplished by going to the /dev directory and running:

    # sh MAKEDEV bpf0

Please see the Handbook entry on device nodes for more information on creating devices.
