But you are using the wrong commands. I have some working scripts. You can find them on www.docum.org. But I advise you to use the htb qdisc. Much easier to set up and to understand. Again, more information on www.docum.org. If you really want to use CBQ, I can give you more information. Just leave a message on the mailing list.
