I'm looking for a solution to audit network traffic usage per user. After a long enough search I was not able to find a solution that suited my needs. It must fit the following requirements: * The traffic must be logged on a uid basis. * Some traffic should not be counted, which is protocol (i.e. non-IP) and IP address based (i.e. no local network). * Of course not have a dramatic effect on performance Hopefully its not to hard for me, thus the tool has some (decent) instructions/documentation. Further I want to keep using my stock application. The platform is Ubuntu 6.06 LTS, and I prefer to have the packages from the repositories, rather than my own complications. Mostly for reasons of testing and maintenance. I would guess this is not directly a netfilter question, but it should be close enough. - Joris
