Hi,

I have some interesting problem with htb , I set up root class and
sub-classess:

$TC qdisc add dev eth0 root handle 1: htb
$TC class add dev eth0 parent 1: classid 1:1 htb rate 1990kbit ceil 2000kbit
$TC class add dev eth0 parent 1:1 classid 1:10 htb rate 190kbit ceil 200kbit
$TC class add dev eth0 parent 1:1 classid 1:11 htb rate 1400kbit ceil
1600kbit
$TC class add dev eth0 parent 1:1 classid 1:12 htb rate 1000kbit ceil
1500kbit
$TC class add dev eth0 parent 1:1 classid 1:13 htb rate 1000kbit ceil
1500kbit
$TC class add dev eth0 parent 1:1 classid 1:14 htb rate 1000kbit ceil
1200kbit

, filters and queuing disciplines :
#filter
$TC filter add dev eth0 protocol ip parent 1:0 prio 1 handle 2 fw flowid
1:10 classid 1:10
$TC filter add dev eth0 protocol ip parent 1:0 prio 1 handle 3 fw flowid
1:11 classid 1:11
$TC filter add dev eth0 protocol ip parent 1:0 prio 2 handle 4 fw flowid
1:12 classid 1:12
$TC filter add dev eth0 protocol ip parent 1:0 prio 3 handle 5 fw flowid
1:13 classid 1:13
$TC filter add dev eth0 protocol ip parent 1:0 prio 1 handle 6 fw flowid
1:14 classid 1:14
(note the packet marking classifier)

adequate lines from firewall script :
[...]
# ftp
$IPTABLES -A FORWARD -p tcp -s 0/0 -d 0/0 --dport 21 -m state --state
NEW,ESTABLISHED -t mangle -j MARK --set-mark 3
# ssh
$$IPTABLES -A FORWARD -p tcp -s 0/0 -d 0/0 --dport 22 -m state --state
NEW,ESTABLISHED -t mangle -j MARK --set-mark 2
# smtp
$IPTABLES -A FORWARD -p tcp -s 0/0 -d 0/0 --dport 25 -m state --state
NEW,ESTABLISHED -t mangle -j MARK --set-mark 4
[...]

#qdisc
$TC qdisc add dev eth0 parent 1:10 handle 20: sfq perturb 10
$TC qdisc add dev eth0 parent 1:11 handle 30: sfq perturb 10
$TC qdisc add dev eth0 parent 1:12 handle 40: sfq perturb 10
$TC qdisc add dev eth0 parent 1:13 handle 50: sfq perturb 10
$TC qdisc add dev eth0 parent 1:14 handle 60: sfq perturb 10

the problem is - all the traffic goes only through root class '1:'

#tc -s qdisc ls dev eth0
qdisc sfq 60: quantum 1514b perturb 10sec
 Sent 0 bytes 0 pkts (dropped 0, overlimits 0)

 qdisc pfifo 50: limit 5p
 Sent 0 bytes 0 pkts (dropped 0, overlimits 0)

 qdisc pfifo 40: limit 5p
 Sent 0 bytes 0 pkts (dropped 0, overlimits 0)

 qdisc pfifo 30: limit 5p
 Sent 0 bytes 0 pkts (dropped 0, overlimits 0)

 qdisc pfifo 20: limit 5p
 Sent 0 bytes 0 pkts (dropped 0, overlimits 0)

 qdisc htb 1: r2q 10 default 0 direct_packets_stat 671
 Sent 392890 bytes 671 pkts (dropped 0, overlimits 0)


I'd be very grateful , if you could help me with this.

thanks in advance.
