Dear list, I have the problem that child classes don''t seem to issue the parent class to borrow from their parent. This is a simplified version of my script: tc qdisc del dev $DEV root tc qdisc add dev $DEV root handle 1: htb default 10 tc class add dev $DEV parent 1: classid 1:1 htb rate 10mbit tc class add dev $DEV parent 1:1 classid 1:10 htb rate 1kbit ceil 512kbit #groups tc class add dev $DEV parent 1: classid 1:f1 htb rate 2048kbit ceil 10mbit burst 50k tc class add dev $DEV parent 1:f1 classid 1:a1 htb rate 20...

Hello... Im trying to setup HTB to allow me to shape traffic from two upstreams that meets on single lan0 interface. I prefer to use HTB qdisc within HTB root qdisc for cleaner rules design. Seems that it doesnt work at all. tc -s class show doesnt show any traffic on other classes attached to HTB qdisc. Linux 2.6.20.7 iproute-...

Hello all, I am with a doubt about QoS solution... I have a 4 Mbit backbone coming from the telco I use... This is the link I serve to my clients, so I make this classes: $TC qdisc add dev $DL root handle 1: htb default 60 CLASS="/sbin/tc class add dev $DL parent" $CLASS 1: classid 1:1 htb rate 4096Kbit $CLASS 1:1 classid 1:10 htb rate 256Kbit ceil 3072Kbit burst 15k $CLASS 1:1 classid 1:20 htb rate 256Kbit ceil 1024Kbit burst 15k $CLASS 1:1 classid 1:30 htb rate 2048Kbit ceil 3072Kbit burst 15k...

Hello everyone, We are working on HTB with TC and would like some clarifications from your part. Our example is as follows. We have one HTB root class and two HTB classes attached to it, as in this figure : 1: HTB | | |...

I''m trying to build a QoS system that would divide the outgoing traffic into four categories, each one also subdivided into two more categories. For that I chose a htb root qdisc subdivided into four classes, each of these classes contains also a htb qdisc. Until these point everything goes well, but when I try to attach a new class to the leaf htb qdisc a problem with the sintaxis arises. Code follows: tc qdisc add dev $DEV root handle...

Hi,lartc I used iproute-060110 with iptables1.3.4 on gentoo 2005r1 kernel 2.6.14-5. I find some error messages in system logfile: HTB: quantum of class 10001 is big. Consider r2q change.

Hi I tryed to use a htb qdisc/class on top of another htb qdisc/class as you can see bellow: #!/bin/bash tc="/sbin/tc" $tc qdisc del dev eth0 root $tc qdisc add dev eth0 root handle 1: htb default 40 $tc class add dev eth0 parent 1: classid 1:1 htb rate 100Mbit burst 15k $tc class add dev eth0 parent 1:1 clas...

Hello, after spending several hours reading archives, I decided to write new post. I successfully set up packet classification, made some basic HTB setup, made some simple graphical representation from HTB statistics data... BUT, I cannot figure out how to refine HTB to get this behaviour: I need that class "p2p" should be the last one to get some link capacity. If I set both RATE and CEIL for "p2p" to some constant value...

Hi everyone, My HTB script is showing me those "r2q change" warnings. I read that I should test with r2q values to gain accuracy and stop the warnings but I made some tests with r2q and with burst and I still get the warnings. Any ideas on this issue will be very helpful. The script seems to be working as th...

Hello, I have made every effort learning QoS. I chose HTB and wrote a script (attached to the message). The problem is error messages in syslog. They appear on heavy load. It looks like: Jun 12 23:00:04 server kernel: KERNEL: assertion (delay > 0 && delay < 5000000) failed at sch_htb.c(411) Jun 12 23:00:41 server last message repeated 12 ti...

Hi, I am new to HTB and in the learning process I want to simulate a slower link on my server to see how qdisc works. I have a 100Mbit connection. I want to simulate a 100K connection and to divide traffic between FTP and SMB. (like in HTB user guide). The problem is that it doesn’t work. I can transfer files with...

HTB performance improvement Hi all ! i''m looking at the performance of the HTB algorithm/implementation because i would like more packets/sec !! this is the scenario of the performance test: i''m using an embedded system with: SPEED CPU: 399,999 MHz RAM: 128 MByte FLASH: 16 MBy...

Hi, I''m trying to make run a simple shaping *through HTB*. I have compiled a new kernel 2.4.21.

Hello, Could you tell me how did you solve your problem? I have exactly the same problem but with this configuration: - linux 2.4.20 kernel, HTB option checked - iproute2-2.4.7-now-ss010824.tar.gz installed, which is the latest version I found at ftp://ftp.sunet.se/pub/Linux/ip-routing/, except for "try" or "do not use" versions. I guess I do not need patching iproute2 and I''m not using an old version of tc eit...

Hi there, I have a question with regards to cascading multiple HTB qdiscs. Assume that I want to build the following hierarchy: (qdisc htb 1:0) -> (class htb 1:1) -> (qdisc htb 2:0) -> (class htb 2:1) -> (class htb 2:2) I want to attache aggregate u32 filters at 1:0 for supernets, then at 2:0 (and 3:0, 4:0, etc), I attach the more specifi...

...-d ... output I need can be obtained in any time - not only at time of error. I''d never write a message like this, but your last sentence (that I''m not willing to help as much as you) disapointed me too much - because I already have problems in my work because spending my time on HTB (I''m solving at least one bug report per month - some of them took pretty long time before discovering that there was no real bug). It is not the way opensource work like. have a nice day, devik > I haven''t forgotten your requests nor am I ignoring you. It didn''t do...

...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: - Why in almost every list of tc rules based on htb class, there is a "tc qdisc dev ... root ... htb default ..." as a root node? Is it mandatory to work with htb class? - I understood that every class node has its own qdisc attached (fifo by default, right?). If that is the case, why when I do "tc qdisc show ..." it JUST sho...
