[LARTC] Traffic shaping problem

[LARTC] Traffic shaping problem

[Andre Meij]

Hi,

(well, my squirrelmail seems to be working again so this is the final
attempt to send a readable mail :) )

I'm trying to use the shaper script from the lartc howto
but the following lines:

# both get Stochastic Fairness:
tc qdisc add dev $DEV parent 1:10 handle 10: sfq perturb 10
tc qdisc add dev $DEV parent 1:20 handle 20: sfq perturb 10

Return:

RTNETLINK answers: Invalid argument
RTNETLINK answers: Invalid argument

I seem to mis something,
my current iproute2 version is: iproute-20010824-r2
Kernel 2.4.19

Can anyone place this?

tnx
Andre

Yes, now it works OK :)

Maybe you don't have SFQ compiled in your kernel, or available as a
loadable module. If any command that sets a "sfq" qdisc fails, and any
other command works, this could be the problem.

Or it could be some kind of syntax error, or reference to a non-existent
"parent". Also remember that standard kernel version 2.4.19 doesn't have
support for HTB, if this is what the script is trying to use.

Hope it helps.

Dear all, 
 
I am a newbie, so excuse me if I ask stupid things.
I have a proxy server with 2 nic, a subnet for wireless lan (with DHCP),
and I would like to limit up/download speed to every client, who is
connected to this network.
After reading howto I think the only one solution is to create classes
for all possible hosts, with 1024k limits  (for one client) and I create
rules to assign classes to IP addresses.
(class 1:1=match 192.168.0.2, class1:2=match 192.168.0.3, etc.)
It means that I have to create 254 (one C class) classes, I'm afraid
that there will be too mutch rules. 
Is there any other solution? 
 
Thank you.
 
Peter.

Depends on your hardware - 254 is not that high.

You can make the filtering alot more efficient by hashing -
