Dear all!
I wrote a little script which logs the amount of bytes which were transfered
over a ppp-line (ADSL/PPPoE).
The problem: this only works untill you do not transfer more than 2 GB
(pppd-limit) or 4 GB (kernel-limit).
Within pppd it seems that there is a problem with the $BYTES_RECVD and
$BYTES_SENT variables which can be used in /etc/ppp/ip-up and -down.
PPPD uses "signed int"-counters instead of an "unsigned-int". This is
not a great problem, a patch is attached to this email (thanks to Evgeni
Gechev).
Unfortunately, this only increases the amount of transfered bytes to 4
GB (kernel-limit).
Is there any chance to increase the kernel-limit in feature
kernel-releases?
Bye,
Michael
