It has been a long time since I used kppp (used to during those dial-up (pre-2004) days). Looks like kppp statistics is confused about kbps (kilo bits per sec.) and KBps (kilo bytes per sec.). Shows KBps as kbps in the logs. Confirmed using ifstat that it is actually KBps and not kbps. Seemed that I had observed this similar problem during the dial-up days. Could someone maintaining kppp please explain why this has not been fixed for so many years.
