I tried this yesterday afternoon, and got a RTNETLINK error message. I think it was "no such file or directory". Then I thought I remembered reading in your documentation that filters couldn't be attached to internal htb qdisc, so I tried to use the same setup with CBQ classes, and that worked. But if you say it can be done, I will take another good look at my code and try again. I would certainly like to be able to use HTB for this purpose, because it has given me great results with link-sharing so far. Thanks for a good and easy to use qdisc..;-) Øystein Løkås
