Well mainly because I couldn't get it to work properly. I found it resetting
the usage stats it keeps occasionally, couldn't pin down why. It wasn't
starting a new log, just resetting em to 0. It mainly happened on machine
reset or link down (my old box is running a little unstable). But I was
updating it every 5 mins via cron hence I couldn't figure out why it was

Another thing is it didn't parse the ipfstat output properly. I put
ppp0|ppp0|internet in ipnames.db but it wouldn't find it in the ipfstat line
for 'count in/out on ppp0 from any to any' etc.

Like I said, I'm pretty much a beginner and netbsd/unix stuff in general so
I wouldn't be surprised if I'd configured something wrong.

I'll probably end up writing an ipacct-like pl script anyway for
hourly/daily/monthly totals and averages from ipfstat.
