Re: Count traffic

You mean the TCP/UDP level byte count will be correctly given by
access.conf. Kernel accounting under various OS would give network level
byte count if required. I matched kernel accounting with other byte
counters and that was almost equal. Do you suggest any byte counters (GNU
GPL if possible).
