Logging Traffic by user @ OpenSSH 3.8.1

Subject: Logging Traffic by user @ OpenSSH 3.8.1
Date: Sat, 3 Sep 2005 00:50:07 +0200 
Hi!

For a productive environment we are currently logging via iptables all
SSH traffic for specific machines. Due to the reason, that multiple
customers use SSH on that machine, we need to log the traffic amount of
each user.
Before, data transfer have most been done via ftp and www by our
customers. We like to provide ssh/sftp access or data tunnelling for all
customers on a shared machine, where the measurement of the usage per
customer seems not possible from my point of view. And in the same
moment all is out of controle!

Current Development environment:
OpenSSH_3.8.1p1 Debian-8.sarge.4, OpenSSL 0.9.7e, 25Oct 2004

Is there anyone having an idea how to create a per user traffic log?

Thanks a lot!
