[LARTC] Bandwidth limiting on HTB.

[LARTC] Bandwidth limiting on HTB.

[krst]

Hi, I've got a problem with HTB bandwidth limiting. I've read many docs
and manuals and I still don't know what is wrong. I've got an internet
connection on ppp0. I'm trying to set some limits on it, but it doesn't
work. Now, I'm trying to set almost the easiest configuration I can
imagine:

tc qdisc add dev ppp0 root handle 1: htb default 10 r2q 1

tc class add dev ppp0 parent 1: classid 1:1 htb rate 10kbps ceil 10kbps
tc class add dev ppp0 parent 1:1 classid 1:10 htb prio 3 rate 5kbps ceil
5kbps
tc class add dev ppp0 parent 1:1 classid 1:20 htb prio 3 rate 5kbps ceil
5kbps

tc qdisc add dev ppp0 parent 1:10 handle 110: sfq perturb 10
tc qdisc add dev ppp0 parent 1:20 handle 120: sfq perturb 10

(I didn't attach filters and ingress qdisc)

I just want to divide my 10kbps bandwidth into two groups each 5kbps. In
fact it doesn't work - when I use wget I download with 10kbps and I can't
see my download in `tc -s -d qdisc` nor in `tc -s -d class ls dev
ppp0`. The counters don't count like they should - in fact only ingress
counts correctly. What can be wrong? I compiled kernel 2.4.20 with all QoS
options (modules where possible) and I downloaded htb3.6-020525.tgz from
Martin Devera's site.

Thanks in advance,
Krzysztof Urbanski

You add the qdisc to the ppp0 device.  So you throttle packets going to the 
internet.  So you are not limiting your download but your upload.
