hi,
i have a simple configuration:
hostA(192.168.100.44) <-----> hostB(192.168.100.45).
I want to shape the traffic from hostB to hostA to a maximum of 10kbps:
hostB# tc qdisc add dev eth0 root handle 1:0 htb default 11
hostB# tc class add dev eth0 parent 1:0 classid 1:1 htb \
rate 200kbps ceil 200kbps
hostB# tc class add dev eth0 parent 1:1 classid 1:10 htb \
rate 10kbps ceil 10kbps
hostB# tc class add dev eth0 parent 1:1 classid 1:11 htb \
rate 100kbps ceil 100kbps
bostB# tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 \
match ip dst 192.168.100.44 flowid 1:10
With this setup, a wget run on hostA downloading from hostB has an
average rate of 97.74 KB/s - it seems to be classified to the default
classid 1:11, not classid 1:10. Also, the class statistics below show
traffic accounted to class 1:11.

hostB is a Slackware 9.1 running recompiled 2.4.22,
cls_u32 and sch_htb loaded as modules.
If instead of matching ip dst for hostA i match ip src for hostB,
it works as expected - rate is 10Kb/s with the following:
hostb# tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 \
match ip src 192.168.100.45 flowid 1:10

i''ve just compiled 2.4.23-rc1 and now it works. it seems the problem was indeed with 2.4.22.
