PQ questions
Hi all,
First, let me say I''ve been most impressed with how quickly and
professionally people on this list ask and answer questions.
Next, let me say that with which I need help is properly configuring strict
PQ, and gathering certain stats. Specifically:
- I need to create a priority queue with four queues (let''s say they are of
high, medium, normal, and low priority)
- I

iptables CLASSIFY and MARK not working?
I have to match my packets based on MAC address, which I cannot do in
the POSTROUTING chain, so I do it in PREROUTING using MARK. Then, I
match on the MARK in the POSTROUTING chain to do a CLASSIFY. But this
does not seem to work:
wireless-r1 bwlimit # iptables -L -v -n -t mangle
Chain PREROUTING (policy ACCEPT 3353K packets, 941M bytes)

hfsc and bps
Hi!
Do you know somthing about hfsc and bps?
There''s no output for speed only for packets. Doesn''t hfsc support such
a field?

RED to use ECN (or work at all?)
Dear Community,
sorry for the somewhat dumb question. Maybe someone has any pointer
to how to setup the RED queue to mark pakets with ECN. In particular
what are appropriate parameter settings for limit, min, max, etc.
All my trials end up with either "RTNETLINK answers: Invalid
argument", although the command line (at least for me) looks fine in
regard to what is said on the

Where is the documentation for IFB ?

Can you tell me where is the documentation for the new IFB (implemented

Inaccurate results without natting the traffic.
Hi folks.
For quite a while, I tried to use linux (cbq and htb) to control
bandwidth in order to replace a cisco equipment used to play this role
on our network.
After trying here and there, with a bunch of different distros,
different versions, different compilations, ... the closest I could
get was as follows:
(using htb.init and cbq.init)
Desired BW ==> Achieved BW
128k ==> 404.78

u32 classifier
Hi folks...!!!
I´ve a problem that i did not solve it.
i want to limit the DOWNLOAD to my hosts (upstream traffic for the firewall)
using IMQ,
If i classify by PORT (source or destination) all seems to be fine,
but...BUT...if i want to restrict by IP addresss (internal IP address) i
can´t do it, because my hosts go to Internet toward the firewall using NAT,
so after NAT my IP address in

htb traffic shaping problem
Hello.
I have a linux server connected to a gigabit lan, and though that lan to a
768kbps/768kbps DSL modem.
I''m trying to shape my webserver running on port 80/443 down to 512kbps,
while leaving all other ports alone. The current configuration script that
I''m using is as follows:

HTB question, tokens.
Hi,
What exactly are the "tokens"?
I thought each token allowed the sending of one byte, that tokens are
stored in a bucket that can hold a max of "burst" tokens, and that this
bucket is filled with tokens at "rate".
But theory does not seem to explain the "tc -s .." output in the
examples below. And I can''t figure out why or how...

marked packets end up in wrong class
Hello,
I have recently started looking at tc and iptables. I have an htb-queue
with two classes 1:10 and 1:20 where 1:20 is the default. Then I use
iptables to mark all packets I send out on eth1. I then filter marked
packets into class 1:10. I expected all packets sent on eth1 to end up in
class 1:10, but some packets still go to 1:20. Did I do it wrong?
Thank you for any help.

tc questions
Hi to all of you!!!
I am a Computer Science student trying to do the pre-grade thesis. I am trying
to develop a free software tool to help administrators to control the
traffic. Right now this tool is based on tc and iptables.
I am having some problems trying to understand tc and tc examples:

tc not matching
Dear all,
I''m having real problems getting tc to do anything useful at all. I''m
also under pressure to get this fixed before the students start arriving
later this month (I work in a university).
In short, I want each IP address to be hard limited to 128kbit down,
64kbit up, never to be allowed more bandwidth than this. It is also
important that the latency remains

why isn''t 1:1 getting the traffic? [filter question]
With the below script, whenever I ping 10.0.16.10 (which matches the
only filter I have), traffic still get''s sent to the default 1:2 class
instead of 1:1 and I don''t know why... Any hints?

dropped bytes in "tc -s class" output
Hi All
Is there any output that counts the number of dropped bytes (not packets)
just as in "Sent" in "tc -s class" output?
I have an HTB arrangement here I can see "dropped" in father/mother 1:0 qdisc
but NOT in each class (they are all zeroes).
These dropped are packets or bytes?
Why these "drops" do not show thenselves in its own class(es) under its

TC (HTB) doesn''t work well when network is congested?
Hi,
I have a server and ten clients in a Gigabit network. The server has
125mbps network bandwidth.
I want that the server has 40Mbps bandwidth reserved for client 1 (IP
192.168.5.141), and the
rest bandwidth is for all other clients.
My script looks like this (I use IFB for incoming traffic):
#!/bin/bash
export TC="/sbin/tc"
$TC qdisc add dev ifb0 root handle 1: htb default 30
