I spotted this site last week, and it prompted me to resurrect a badly decayed RAQ3i - leaky caps & stalled fans to use as an adsl traffic monitor and control appliance.
I started last evening and today it is up and running raqcop.
Excellent work on the port.
I really would like to add ip traffic quota.
I see the ipt_quota module is present.
Anybody looked at that yet?
I have something called Copfilter installed on one of my test boxes running ipcop (raqcop) 1.4.20 which is still svn and hasn't been released yet and it installed no problem. Not sure if this will do what you would like to do.
