Kernel panic when using wrr qd
For some time now im trying to get to know what causes such
configuration of QOS (kernel 2.4.25-2.4.28 + IMQ patch and ofcourse wrr):

DEV_IN=imq0
ifconfig $DEV_IN down
ifconfig $DEV_IN up

tc class add dev ${DEV_IN} parent 1:0 classid 1:10 htb rate 1000kbit burst
1kbit prio 1
tc qdisc add dev ${DEV_IN} parent 1:10

share bandwith fairly
Dear members,
I am trying to share the bandwith for all users fairly. because some users heavily uses p2p programs and a few hosts consume most of bandwith. when we limit each flow it does not work as one client has many connection at same time.
Firstly I tried to write a script that use
the ipfm(which accounts traffic usage) logs as follow
.extract ip addresses heavy bandwith users from

problem with wrr+prio
I have set up wrr successfully on my bridge/shaper machine. That much
works fine. I originally used sfq in the inner classes. However, there
was a problem with high-bandwidth connections (web downloads,
bittorrent) starving low-bandwidth low-latency connections like ssh. I
would like to use prio or similar to prioritize the interactive traffic,
but it does not seem to work. I have tested with

ingress/imq shaping setup
hi list,
i''m about to setup traffic shaping on a server and got some small
questions about the setup. i read alot of docs/howto''s but there are
still some questions i''d like to ask.
setup on the box is:
- external if is ppp0 (dsl)
- internal if in eth0 (with ~15 nat''ed boxes)
- openvpn at tun1
since all ppl on the lan feel like they have to use p2p i decided

esfq ? or wrr ?
Hi
If I have a HTB class with 128kbit, and I want to
put "N" users in that class ( in order to share
bandwidth fairly ) ,
which is better for me ? esfq (hash dst) or wrr ?
I would attach esfq or wrr to HTB parent class.
Also I''ve readed on Jim script that over WRR put
a RED qdisc, but I don''t understand it.

tc troubles with pfifo_fast qdisc on 2.4.23 kernel
Hi!
I was updated kernel from 2.4.22 to 2.4.23
and now tc tools can''t correctly determine default (pfifo_fast) qdisc on interface:
# tc/tc qdisc ls dev ppp0
qdisc pfifo_fast 0: [Unknown qdisc, optlen=20]
but, if I assign f.e. cbq qdisc for some device all show correctly:
# tc/tc qdisc ls dev ppp1
qdisc tbf 8009: rate 32Kbit burst 10Kb lat 1.5s
qdisc cbq 66: rate 10Mbit

pfifo_fast as leaf qdisc for htb classes
Thank you Andy! I did''t find why I could''t use the fw
match in ingress. Now it works.
Now I ran into another problem:
When I try to add a pfifo_fast leaf qdisc dor htb
classes it seg.-faults. Is pfifo_fast a special qdisc?
I can succesfully add other type of qdiscs.
I found that a similar problem was reported in
february on a MIPS architecture.

rate limited pfifo_fast?
Hi,
I have a cable modem with a bandwidth capped upload rate. I''d like to
prioritize packets going outbound according to the TOS header of the IP
field. I''ve read through the LARTC Howto several times, and I think I have
a good feel for the information it it. It also seems that what I''m trying
to do is pretty straight-forward and common. Unfortunately, the HOWTO

multiple wrr as child of htb
Hi all,
Here''s the situation.
I have 80 users sharing a internet link of 5Mb link.
The users are grouped in /29 ip addr classes so I have 10 classes of users
I want to create a root htb, then 10 htb childs each with 0.5Mb
bandwidth. The traffic will be directed to each class using tc filters.
Now, I want that each of 8 users from each class to share equally the
class bandwidth. Can I

[Bridge] Transparent shaper with 2.6 kernel
Hi all!
I'm trying to make a transparent shaper with kernel 2.6.11
I have done this and used it many times on 2.4.25 kernel and
ebtables-brnf-5_vs_2.4.25.diff
On 2.4.25 I have been using U32 classifiers and HTB.
On 2.6.11 even with :

Round Robin trafic shapping
I have this problem:
I have an Internet line input with variable speed. I have a max speed and a
min speed: Vmax and Vmin.
The speed is always changing between Vmax and Vmin. I want to share the
actual bandwidth (you don''t not how much, you only know the speed is between
Vmax and Vmin) for N clients. The bandwidth should be shared so nobody can
get more bandwidth than the others.

pfifo_fast with bands
Hello,
I read about the pfifo_fast has 3 bands, which allow you to prioritize
traffic into these bands. I cannot find anything about these bands in the tc
command reference (http://linux.bergqvist.se/tc/). I might be looking the
wrong place - in which case, where should I look for help with this qdisc?
The idea is to give "time-critical" sessions such as ssh, telnet etc.

Suggestion - table of QoS mechanisms
Hi,
A thought for the list. As I mentioned in another
posting, there are a lot of QoS mechanisms out there.
Linux supports some, but not all. Some patchsets add
others, but don''t work for all kernels. There are also
userland implementations, usually sitting in software
routers, but there are other packages.
Would it be helpful if I worked on a table of what''s

Simple pfifo_fast question
Hello,
I use HTB on IMQ, and I would like to use pfifo_fast on my HTB
leafs.
Do I need to add a pfifo_fast qdisc to my HTB class, or this is
the default one?
I tryed to add and I got:
RTNETLINK answers: Invalid argument
It looks like pfifo_fast qdisc is not supported on HTB leaf...
Any comments?
Regards,
Thomas

Closed ports and traffic shaping
First off, please excuse the cross post between lartc and netfiler,
the line between the two is very blurred here (at least for me)...
A thought just crossed my mind now while working on a new iptables/tc
collaboration for a project.
I use iptables to basically seal off a linux gateway, we''re very
restrictive on what users can do on the connection. For now I''m using

[Bridge] [RELEASE] ebtables-brnf-3-vs-2.4.22 and ebtables-2-0-6
Hi,
At http://sourceforge.net/projects/ebtables/ you can find the following new
releases:
ebtables-brnf-3-vs-2.4.22
Changes:
- let iptables see VLAN tagged IP traffic
- bugfix for queued packets that get mangled in userspace
- ebt_among module (Grzegorz Borowiak)
- ebt_limit module (Tom Marshall)
The patch compiles but I've done no further tests, but I probably didn't screw
up.

Where to get working esfq hash src ip?
Hi,
It is exactly what I need except one thing. I don''t know exactly if my
router is the right place to apply QoS policy. It has two network interfaces
and both are 10Mbit/s. The slow part of the network is little bit more far.
On their QoS we have 2Mbit and I want all our users to divide this bandwidth
equally but also don''t want to unnecessarily restrain their bandwith and to

ESFQ updates
Hi.
On Mar 12, Corey Hickey posted
here(http://mailman.ds9a.nl/pipermail/lartc/2004q1/012038.html)
an updated esfq patch for kernel 2.6.
Has anyone backported it to kernel 2.4 ? Original esfq patch is not being
kept in sync with kernel sfq, it seems.
What people have been using with esfq and kernel 2.4.25, the original 2002
esfq patch ?
