When it comes to network accounting the following may be of interest - there was a presentation at the linuxtag open source conference: http://www.linuxtag.org/typo3site/freecongress-details.html?&talkid=131 Network accounting was demonstrated based on the ip_conntrack module in the kernel. Some new enhancements of ip_conntrack solve some problems you have with accounting in userspace with single ip_tables rules for each IP-Address or similar userspace solutions. You don't have the overhead of transfering huge amounts of data to userspace or getting endless rulesets as you have with previous approaches. Sorry, I did not use it myself and I don't know a link to further information, but searching for ip_conntrack may give some hints. -- Andreas
