I was thinking that it would be nice if netstat had an option to not show
network interfaces that don't appear to be being used.

For example, "netstat -inv" shows me stats for ppp0, sl0, strip0, tun0,
gre0, ipip0, gif0 and more. (Sixteen lines of zeros for me.)

Maybe, /etc/daily should have:

 netstat -inv  | egrep -v '*0 *0 *0 *0 *0'

But maybe not, because then you may not get a report on an interface you
wanted.

What is the normal may with dealing with this? (Don't have the interfaces
configured in the first place?)

Any other comments?
