I have a problem in setting up HTB.
It appears filters doesn't work at all, besides "tc filter show" show it as
being correctly configured.
Class 1:10 never sent any traffic, but as iptables show below, it should be
sending packets.
The HTB version I'm using is 3.3, with kernel 2.4.17.
The setup is as follows:
---------------------------------------------------------------
tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1 htb default 20 r2q 10
tc class add dev eth0 parent 1: classid 1:2 htb rate 256kbit
tc class add dev eth0 parent 1:2 classid 1:10 htb rate 26kbit ceil 128kbit
prio
1
tc qdisc add dev eth0 parent 1:10 handle 10 sfq perturb 10
tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match ip sport 23
0xffff classid 1:10
tc class add dev eth0 parent 1:2 classid 1:20 htb rate 220kbit ceil 256kbit
prio 2
tc qdisc add dev eth0 parent 1:20 handle 20 sfq perturb 10
---------------------------------------------------------------
The stats:
---------------------------------------------------------------
[root@NL1000 htb]# tc -s -d qdisc show

So, what is going wrong?
Thanks in advance,
