htb root don''t reach ceil rate?
Hello,
i have a htb setup where the root and (nearly) all child classes has a
ceil rate with max up from my adsl line. But the root class don''t reach
the ceil value but some childs are get a huge backlog.

Weird rate in HTB
Dear all,
First, sorry for my bad English ..
To night one of my client is the victim of UDP attack from internet. It''s tons
of UDP packets from internet with destination to port 80. But when I look at
class of that victim client, the actual class rate is over than configured
rate class.
Below is my screen capture. You can see at class 1:913 which have actual rate

HTB - Rate errors
Hi,
I''m trying to get HTB working correctly on Centos4 (RHEL-based) with

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

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):

FW: differing rate and ceil values
Hello all, when running tc -s -d class show dev eth, the parent class rate
and ceil are different to the configuration?
his is the first time I have used HTB so I may have made some basic

Thanks in advance

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?

Hmmm... Weird results with HTB in kernel 2.6.11
Hi all,
I have been getting some strange results with HTB in kernel 2.6.11, and
was wondering if anybody could give me some advice. Also, if someone
could direct me to the changelog for the recent versions so I can see if
it is worth upgrading?
Anyway, the problem can best be summed up by looking at the output of
''tc -s -d class show dev eth0''. Some of the relevant results

htb traffic shaping problem

I have a linux server connected to a gigabit lan, and though that lan to a

htb overrate with 2.6.16
Hi
Here is something that worked with with 2.6.10-1.771_FC2smp and stopped
working when I upgraded to 2.6.16-1.2069_FC4smp.
These are fedora kernels and the network controller is an Intel Gbit
(e1000) running a 100 Mbps Full Duplex.
Don''t know how or if this matters but the 2.6.10 kernel has
CONFIG_X86_HZ=1000 and the 2.6.16 has CONFIG_HZ=250
The idea is to just shape to , say 2Mbit, a

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...

htb2 -> htb3 problems
Hello!
I need to switch from htb2 to htb3, because of speed issues (for me,
htb2 is unable to handle more then 100mbit duplex with ~550 classes),
kernel profiling shows htb_dequeue_prio at 1st place with 3x isolation.
So, I''ve moved from 2.4.19 to 2.4.25 kernel (hi-pac for classification/marking
and htb3 for queueing), and traffic rate drop from 100 to 20mbit.
What can be wrong? The

tc counters "problem"
Hi, I''m using tc and HTB to shape my outgoing ADSL traffic. I was trying to
make some graphs on the classes by meassuring the "sent bytes" of each class
using rrdtool to store the data (as kbps after conversion). I expected that
meassuring the root class I would get values similar that the ones I get
measuring the interface counters but they differ by a large amount.
