bpf6?  Initially, only 5 BPF devices are created; if they're all busy, the BPF driver will create more - but they won't 
get their ownership or permissions changed automatically.  (Ideally, there would be a /dev/bpf cloning device, so only 
it would need to have its ownership and permissions changed, and libpcap would just open that to get a new BPF 
instance, but nobody's made a cloning BPF device yet.)

Yes.

        1) What does the command "id" print?

        2) What does the command "ls -l /dev/bpf*" print?
