[LARTC] tc problem

[Alexandru Coseru]

Hello..

I have a linux box and I want to make priority on traffic generated by my
LAN's computers..
I don't have a guaranted bandwidth, so I wanna use sfq...

I want to make traffic to port 80 , 443 , 25 & 110  PRIORITY 1

Traffic src or dest 192.168.0.2  to make priority 2

And the rest to put it in proiority 3..


I did the following :

tc qdisc add dev eth0 root handle 1: prio

 tc qdisc add dev eth0 parent 1:1 handle 10: sfq
 tc qdisc add dev eth0 parent 1:2 handle 20: sfq
 tc qdisc add dev eth0 parent 1:3 handle 30: sfq

now , when i do :

tc filter add dev eth0 protocol ip parent 10: prio 1 u32 match ip sport 80
0xffff flowid 10:1

I get an : RTNETLINK answers: Invalid argument

but , if I'm typing

tc filter add dev eth0 protocol ip parent 1: prio 1 u32 match ip sport 80
0xffff flowid 1:1
it's working (at least I don't have any messages..)


I've compiled the kernel , and all options were selected "in kernel" , not
as modules...  (iptables , cbq , sfq , etc..)


                                    Thanks

Euh, your first command is wrong and your second not.  You have to attach the 
filter to the root qdisc (parent 1:) and point it to a class (flowid 1:1) 
like you did in the first filter command.  That's all.

[root@alexcos root]# tc qdisc del dev eth1 root
[root@alexcos root]# tc qdisc add dev eth1 root handle 10: prio
[root@alexcos root]# tc qdisc add dev eth1 parent 10:1 handle 20:est 1sec 8
sec bfifo
Unknown qdisc "1sec", hence option "8" is unparsable
[root@alexcos root]# tc qdisc add dev eth1 parent 10:1 handle 20:est 1 sec 8
sec bfifo
Unknown qdisc "1", hence option "sec" is unparsable




can somebody tell me what is wrong here ?



                                                Thanks
                                                Alex

Yes.  You are executing a wrong command.  See the lartc.org howto for 
examples.

Put a space between "20:" and "est".
Good luck!
