Hi! Soryr about being a whiner, not enough sleep and too much frustration don't become too well. In any case, I have succeeded with the shaping now. The problem seems to have been twofold. First of all I had the rate too high for the actual throughput. We have a 1mbit connection to the internet, and after lowering the rate of the parent to 800kbit, and sharing that between the children, it worked. The second thing I did was change the SFQ_DEPTH, which seemed to help a lot too. The SCHED_CPU hack didn't work, for some reason the clock must be screwed or something. In any case, many thanks for all of this, it will make life a lot easier for some people in our organisation. All the best, .peter _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
