Hi, and thanks a _lot_ for the answers.

But, if I set LEAF=none, the mother class will not do any Fair Quing.. And,
that's what I want. Exept that protocols like ssh and such should always
come through first.

Agree, the question is how do I do that..
I've been playing around with different names on the classes, different
classid's and so on, trying to figure out how I control what class will come
first. Now, Maybe the PRIO is the thing that sets that, but then, why didn't
it work then, ssh got prio 1 in my configuration..

I will try that again then.

No problem. These answers are found by google - a lot. Think of answering
these questions as being an audience for the internet.

Ok. That's often the most important part, precisely specifying what you
want.

Edit the script and change this line:
### Uncomment for debugging
#LOG_FILE="/var/run/cbq-$1"

Then it should be easy to see what is happening, or to change it.

Also, look at HTB, it is very well suited for what you try to achieve.
