HTB - Rate errors
Hi,
I''m trying to get HTB working correctly on Centos4 (RHEL-based) with
kernel 2.6.9-34.EL. I have two gigabit network interfaces bridged
together and I have created the following:
tc qdisc add dev eth2 root handle 1: htb default 1 r2q 8000
tc class add dev eth2 parent 1: classid 1:1 htb rate 100Mbit burst 24k
cburst 24k
(I have been trying different parameters).
The network is

how to change classful netem loss probability?
Hi,
I am using netem to add loss and then adding another qdisc within netem
according to the wiki. Then i want to change the netem drop probability
without having to delete the qdisc and recreate it. I try it but I get
invalid argument:
thorium-ini hedpe # tc qdisc add dev ath0 root handle 1:0 netem drop 1%
thorium-ini hedpe # tc qdisc add dev ath0 parent 1:1 handle 10: xcp

Problems upgrading samba
I have inheirited a samba-1.9.18p4 running on an alpha machine. I want
to upgrade it to something newer. The machine serves a disk filled with
network installs of our commercial software.
I have tried installing both samba-2.0.7 and samba-2.2.0-alpha2, but
both cause failures on the DOS machines. In specific, Corel WordPerfect

Teql and NetEm can''t work together
Thanks in advance!
Summary: when I load netem and teql together, teql doesn''t work
correctly. (If I load teql only, everything is fine)
I loaded both netem and teql. Netem is associated with eth0, and teql is
associated with both eth0 and eth1. But traffic only goes out of eth1.
Attached are the commands that I used to configure teql and netem (on
machine 1), and commands to

Please Help: applying multiple different delays with netem
I''m trying to use tc and netem to delay packets from several different
machines as they exit via eth0. Assume two source IPs, 10.0.0.122 and
10.0.0.133. I''d like to delay packets from the first one by 200ms, and
packets from the second one by 300 ms. Any other traffic should be sent
out normally. Here''s what I tried:

netem usage example
I''m trying to setup a netem delay with no luck (using iproute2-2.6.8,
compilation broke during arpd compile, so I use the
tc binary in the tc/ subdir, there''s also a q_netem.so there).
kernel is 2.6.8.1, compile with CPU cycle counter as time reference.
I was using sch_delay of 2.6.7 happily with something like:
tc qdisc add dev eth0 root 1: delay latency 1ms rate 35M

How to add multiple filters and netem rules on a single interface?
Hi!
We want to run TCP streams to several port numbers through one interface,
each with a different delay set by Netem.
E.g. TCP streams to port 80 could have 50ms delay, while TCP streams to port
81 could have 100 ms delay and so on.
We have tried to solve this by using a combination of tc filter and netem
rules, but we can''t get it quite right.
We are considering one class per port,

netem bug?
Hi all,
I''m running some tests with netem and I noticed some strange behaviour
that looks like a bug: I''m pinging another machine and adding delay with
netem. When I tell netem to give me a 10ms delay, it works fine. The
problem is that when I ask for a 11ms delay, it gives me 20ms! It
happens for any value between 11ms an 20ms, and it repeats for values
over 20ms, now

OSPF with Netem
Hi all,
I am currently trying to emulate a satellite link, via Netem, on a testbed which is OSPF-enabled.
I''d like to set up a Netem box between two routers.
Since all routing between routers is dynamic, I''m wondering how to set up OSPF on my Netem box?
Could someone indicate me if it is feasible and give me some guidelines to possibly do so?
Thanks in advance,
Vincent.

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.

Thats exactly what I want from HTB to do..to prio the borrowed bandwidth.

Qdisc requeue should be void?
There is an design problem with the qdisc interface that causes qlen related bugs
in netem, tbf, and other qdisc''s that peek at the top of the queue. The problem is
that requeue needs to be called from the dequeue function but requeue can fail.
If requeue fails, then the calling qdisc can not properly handle the error. If it
returns NULL, then the parent''s expectation about qlen

simple question
Hello
everybody,
I''m trying to set up netem on a SuSE box (kernel 2.6.16), but I''m having some weird problems, considering that on my Gentoo laptop (kernel 2.6.17) it worked
fine.
If I write:

and then try pinging another machine over eth0, I get a 24ms delay but no packet loss (while on my laptop I get 21ms and a correct

A HTB problem
My hardware is a Linksys AP with MIPS 300MHz and Linux kernel 2.4.20.
The traffics are from two LAN switch ports to WAN port. And the traffics
are generate at a rate of 80Mbit. So the total traffic to WAN port is
160Mbit. The shaping works well that the traffic to WAN port is about
50/30Mbit according to configuration. But the priority seems strange
when the root rate is 50Mbit.
