The ip acconting stuff works via the Linux ipfwadm command...  You'll need
to add the appropriat commands to your rc.local for this to work  mine
looks like this.

ipfwadm -A -a -P all -Dmorn.MageNet.com/32          -S0.0.0.0/0 
ipfwadm -A -a -P all -Smorn.MageNet.com/32	    -D0.0.0.0/0

I'll package this all up with some better docs later...  as well as add
the CPU monitoring stuff...  I'm still thinking about that one...  any
feedback?

Julie
