[LARTC] tc filter question

[philipp.berndt]

Hello.

I tried this:

$ ./tc qdisc add dev ppp0 root handle 1:0 htb default 12
$ ./tc class add dev ppp0 parent 1:0 classid 1:1 htb rate 125kbit ceil 125kbit
$ ./tc class add dev ppp0 parent 1:1 classid 1:10 htb rate 10kbit ceil 125kbit 
prio 0

$ iptables .... -j MARK --set-mark 11

$ ./tc filter add dev ppp0 parent 1:0 prio 0 protocol ip handle 10 fw flowid 
1:10
RTNETLINK answers: Invalid argument

Can anybody tell me what's wrong with the last line?

I tried it with tc from
http://luxik.cdi.cz/~devik/qos/htb/v3/htb3.6-020525.tgz
and from iproute2-2.4.7-340.rpm (SuSE 8.1).

Do I need some other kernel module?

Regards,
Philipp

Recompile Your kernel with option CONFIG_NET_CLS_FW.
Networking options  --->QoS and/or fair queueing  --->Firewall based classifier

[LARTC] tc filter question.

[Σταμάτης Κεκές]

Well so far I've used tc with htb with success, installed on a machine 
with two ethernet interfaces acting as a bridge. On eth0 I applied the 
ougoing policy and on eth1 the incomming.
 My users ussualy they use lot of protocols ( IRC, KAZAA and many more ) 
the IRC protocol by itself is from port 6667 up to 7000. So as you 
understand I have to write 300 and more lines for filtering the IRC 
traffic to feed it in a class that I've made up for the minimal 
bandwidth allocation.
 My problem is on how to make a filter to accept sport 6667-7000. I've 
searched but I didn't found anything usefull in the list archives.
 Is there any way to do that or I have to make one filter per port ?

 Best regards
  Stamatis

You can use iptables (for example) to mark the packets in the range of
ports you want and issue one filter for this mark

Thanks for the answer.
Well I thought that solution but I want to have all the filtering 
related with QoS in one machine.
Otherwise I have to keep lot of docs up2date dor the firewall and the 
shaper too.
Any other suggestion ?

Didn't got it! Why do you think you can't have all in one machine?
You can have your FW *and* traffic control in one machine or split it in
two if you want.
Its up to you to decide. Obviously you cannot pass marks between two
machines if you choose the splitted solution. Marks and bwcontrol must
reside in the same machine.

No I want them separate. The spaher is in one machine and the firewall 
is on the second machine.
When I spoke about filtering I ment the classification rules and not the 
netfilter.

I want to classify the packets without the need of firewall. Thats what 
I ment.
Anyway thanks for the advice

[LARTC] tc filter question

[Daniel]

Dear all,

I have big question in my mind about "tc filter" sintax. If I give "tc -s -d 
filter sh dev eth0" command, then the output is like below :

filter parent 1: protocol ip pref 1 u32
filter parent 1: protocol ip pref 1 u32 fh 800: ht divisor 1
filter parent 1: protocol ip pref 1 u32 fh 800::800 order 2048 key ht 800 bkt 
0 flowid 1:2  (rule hit 21553629
 success 37907)
  match 00160000/ffff0000 at 20 (success 37907 )

...

My question is :
1. What is "fh 800:" and "fh 800::800" mean ?
2. How I change the value "800" in "fh 800::800" ? I'm guessing this is 
default value and I need to change that because my filter rule can be more 
than 0xfff line.

Thanks for all,

Daniel

There is a rather unclear howto chapter: 
http://lartc.org/howto/lartc.adv-filter.hashing.html

But it is very correct. Try it (actually, I understood it not from the first 
attempt ;))

Hi, that values are for the hash-tables of u32, see:

Also check http://ace-host.stuart.id.au/russell/files/tc/doc/cls_u32.txt

Old howto misses a few important things.
