Hello all,
I am trying to set up a simple htb based system, where packets with
source ip 10.0.0.1 should have their own class.
I plan to use tcng to set it up easier.
Is there something wrong in my tcng file ?
~/tcng$ cat htb
/*
*/
#include "fields.tc"
#include "ports.tc"
dev eth0 {
htb ( ) {
class ( rate 600kbps, ceil 600kbps )
{
class () if ip_src == 10.0.0.1 ;
class (default) ;
}
}
}
When I compile it, I get :
~/tcng$ tcc htb
# ================================ Device eth0
tc qdisc add dev eth0 handle 1:0 root htb default 3
tc class add dev eth0 parent 1:0 classid 1:1 htb rate 75000bps ceil
75000bps
tc class add dev eth0 parent 1:1 classid 1:2 htb rate 75000bps ceil
75000bps
tc class add dev eth0 parent 1:1 classid 1:3 htb rate 75000bps ceil
75000bps
tc filter add dev eth0 parent 1:1 protocol all prio 1 u32 match u32
0xa000001 0xffffffff at 12 classid 1:2
which is not working as expected.
Packets never get matched. From what I understand of tc (not too much),
the filter should have been :
tc filter add dev eth0 parent 1:0 protocol all prio 1 u32 match u32
0xa000001 0xffffffff at 12 classid 1:2
(I replaced parent 1:1 by parent 1:0).
I tried this setup and it works as expected (at least : packets from the
server gets matched, other don''t. I have used tc -s class show dev eth0
to see it).
Do I miss something ?
Thank you.

try adapting the following to your needs ... it''s been working for me.
roughly similar to wondershaper excepting that it is in tcng:
i have a ppp interface on an analog modem so in my firewall i mark
packets coming in from this device as following:
iptables --append PREROUTING --table mangle --in-interface ppp0 \
--jump MARK --set-mark 0x7

Thank you for your help. this setup is creating an additionnal qdisc (dsmark). For performance reasons, I would prefer using filters directly attached to htb qdisc. I think it is possible, at least it seems to be possible with tc (not tcng). It seems to me that tcc is doing something wrong with htb and indexes, do I miss something ? Thank you.

salut clemment,
well, i see better now -- you could try something like:
#include "fields.tc"
#include "ports.tc"
dev eth0 {
htb () {
class ( rate 600kbps, ceil 600kbps ) if ip_src == 10.0.0.1;
}
}
cheers
