    Hello all,

    I am trying to match some conections using u32 but I tryed this:

[root@ns1 ~]# tc filter add dev eth1 parent 1:0 protocol ip prio 1 u32 
match ip src 0/0 match ip dst 0/0 match ip sport 80 0xffff flowid 1:10
RTNETLINK answers: Invalid argument
We have an error talking to the kernel
[root@ns1 ~]#

    I have this class at device eth1:

[root@ns1 ~]# tc class show dev eth1
class htb 1:1 root rate 100Mbit ceil 100Mbit burst 18412b cburst 51587b
class htb 1:10 parent 1:1 leaf 10: prio 1 rate 3Mbit ceil 3Mbit burst 
18Kb cburst 3099b
class htb 1:20 parent 1:1 leaf 20: prio 5 rate 500Kbit ceil 500Kbit 
burst 18Kb cburst 1849b

    And this qdisc:

[root@ns1 ~]# tc qdisc show dev eth1
qdisc htb 1: r2q 10 default 20 direct_packets_stat 10
qdisc sfq 10: parent 1:10 limit 128p quantum 1514b perturb 10sec
qdisc sfq 20: parent 1:20 limit 128p quantum 1514b perturb 10sec

    I have looked into kernel and into this paramenter:

Networking > Networking Options > U32 Classifier (module)

    It is enable as a module.

    Can someone help me? My box is a Fedora Core 3 using kernel 2.6.13.4.

PS.: Thanks all guys who have answered me about my other question (QoS). 
It was very useful hints. Now I think my QoS is working almost 100% ok.

Att,

Nataniel Klug
