domU on v3.2 is not booting
hi all,
I installed v3.2 from source and now dom0 is booting well. But when I
tried to start domU it shows the following error message and seems
hanging.

What determines DROP versus delay ("BACKLOG")?
HTB:

I would like to increase "backlog" because I think that would decrease

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:

Re: LARTC Digest, Vol 27, Issue 26
Hi folks...!!!
I need to generate qdisc statistics to show my 4 class (10, 20, 30, 40),
i`ve all working with HTB and so on, but i need to graph this results
e.gwith RRDTOOL.
I found a script made in perl, that can to graph my 4 class, but i need to
know which IP address on my LAN are using the bandwidth too, in other hand i
need to classify the traffic by IP to show.

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

why isn''t 1:1 getting the traffic? [filter question]
With the below script, whenever I ping 10.0.16.10 (which matches the

instead of 1:1 and I don''t know why... Any hints?

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)

Where is the documentation for IFB ?

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

Determing the pfifo backlog
Greetings --
in the "Linux Advanced Routing & Traffic Control HOWTO"
chapter 14.1 on bfifo/pfifo it says that:
"you can use this qdisc to determine the backlog on your interface".
But it does not say exactly how.
Command [#tc -s qdisc ls] outputs the number of packets sent so far
but it does not output any info about the backlog.
My first question is whether a command

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

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

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

question on scalability
Hello All,
We have a Linux cluster application that uses openssh as its inter-node
communication mechanism and we've recently run into a problem that points
to a potential scalability issue in openssh code.
Our client nodes systematically open ssh connections to the server node to
execute an administrative command. When establishing socket connections,
the server side sometimes fails to

Re: htb traffic shaping problem (Charlie Meyer)
Eric,
I''ve attached the output from the command you requested below.
I''m using kernel 2.6.17.12 and tc version ss060323. I''m have a nforce4
onboard giggabit controller using the forcedeth driver, if that makes a
difference.
Charlie,
I''ll take a look at the Apache model for throttling, thanks. I was going

Problem with the tc statistcis
I had a linux wireless router. I would like to monitor the queue lengh
of the wireless interface. By default, the wifi0 interface is with
pfifo_fast qdisc which does not report backlog packet. I replaced
pfifo_fast with pfifo:
''tc qdisc replace dev wifi0 root pfifo''
Then I use iperf to send UDP pkts faster than the interface can handle
but when I read the qdisc, the result is

htb traffic shaping problem
Hello.
I have a linux server connected to a gigabit lan, and though that lan to a

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:
