Jay, [ Note for posterity: The term "blackhole" is used as a route type in the linux routing tables [1], and, as far as I know is not a term in traffic control. This is about dropping traffic using traffic control mechanisms. ] : Im using a linux bridge to do traffic shaping for my school. Recently : the decided they want to drop all p2p traffic possible [ snip ] : What I am wondering is what is the best way to use the traffic control : stuff to drop traffic? Should I just use a qdisc/class with a rate of : 0 or is there some way to specify the traffic should be dropped? You can simply attach a policer to the filter which identifies the traffic and use a drop action. Add the following to the filter which identifies the traffic you wish to drop. Now, the filter will select all packets based on your classifier, and the policer will drop all traffic so matched. police rate 1bps burst 1 action drop/drop Best of luck, -Martin -- Martin A.
