LARTC - Apr 2005 - Packets Going to default class

Hi

I have tested with FC3 but iam not able get any good results on that.
in the list some one recomend me that  > 3.17 HTB should work

I saw latest FC4 test2 has the HTB 3.17 with iptables 1.3.0

i have install in my P4 box, and trying to test

when iam uploading its working perfect, but when iam downloading its going 
to default class
can some one experinced the same problem

below is the my config

$TC qdisc add dev $IFACE root handle 1: htb default 15
$TC class add dev $IFACE parent 1: classid 1:1 htb rate ${CEIL}kbit ceil 
${CEIL}kbit
$TC class add dev $IFACE parent 1:1 classid 1:10 htb rate  512kbit ceil 
512kbit prio 0
$TC class add dev $IFACE parent 1:1 classid 1:15 htb rate 256kbit ceil 
256kbit prio 0
$TC qdisc add dev $IFACE parent 1:10 handle 10: sfq perturb 10
$TC qdisc add dev $IFACE parent 1:15 handle 15: sfq perturb 10
$TC filter add dev $IFACE parent 1:0 protocol ip prio 0 handle 10 fw classid 
1:10
$TC filter add dev $IFACE parent 1:0 protocol ip prio 0 handle 15 fw classid 
1:15

$TC qdisc add dev $NFACE root handle 2: htb default 40
$TC class add dev $NFACE parent 2: classid 2:1 htb rate ${CEIL}kbit ceil 
${CEIL}kbit
$TC class add dev $NFACE parent 2:1 classid 2:20 htb rate 512kbit ceil 
512kbit prio 0
$TC class add dev $NFACE parent 2:1 classid 2:40 htb rate 256kbit ceil 
256kbit prio 0
$TC qdisc add dev $NFACE parent 2:20 handle 20: sfq perturb 10
$TC qdisc add dev $NFACE parent 2:40 handle 40: sfq perturb 10
$TC filter add dev $NFACE parent 2:0 protocol ip prio 0 handle 20 fw classid 
2:20
$TC filter add dev $NFACE parent 2:0 protocol ip prio 0 handle 40 fw classid 
2:40

$I -t mangle -A FORWARD  -s a.b.c.d/24 -d 0/0 --j MARK --set-mark 10 #
$I -t mangle -A FORWARD  -s 0/0 -d a.b.c.d/24 --j MARK --set-mark 20 #

the out put show like below for the download... here can observe that all 
the traffic going to 2:40 instead of 2:20

I can''t see why that doesn''t work for you - A copy and paste
of it works
OK for me.

You don''t really need the filters for default classes and it''s
best to
delete the root qdisc before you add a new one.

Maybe you still had some filters around from an earlier test that 
messesd things up.

I am using the latest TC, iptables and 2.6.12-rc1.
