A few weeks ago I had the idea to lonk up the tarpit feature with the pbs tools. So that you can configure tarpit better. You would have the possibility to set the # of messages per connections and the # of connections per timeframe. To support it a major rewrite/change is necessary (pbsdbd needs to support a pbscheck counter and some glue is needed in pbscheck). In other words nothing trivial. That is a feature I will add somewhen in the next time (time ~= 1 month). A short way sollution could be http://dial-spam-block.sourceforge.net/ the idea of the tarpit-pbs lonk up comes from there (or better from a beer session with one of the writer of dial-spam-block). -- :wq Claudio
