Ahh, I assume you patched and recompiled your 2.6.8.1.

I just tried the script below on 2.4.24 and 2.6.8.1 and it works as I 
expect.

I checked rates with iptraf and tc -s class ls dev ppp0. If you use 
htb's rate counter than be aware it uses a long average >60 sec and I 
notice that on my 2.6.8.1 setup it says bit where it probably should say 
bps (= bytes per sec).

Does it work for you ?

If you want to graph then add some queues.

Andy.
