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

Hello, I have a serious problem with HTB which I wasn''t able to solve myself. I run a masquerading router with ppp0 as interface to the Internet. Three clients need to share a downstream of 1 MBit, which I want to divide with tc. When I see a packet being forwarded to one of these clients, I give it the appropriate unique mark: iptables -t mangle -A FORWARD -d 192.168.34.141 -j MARK

Hi all, a while ago one of my work colleagues attended a seminar with Ted Tso, and at the time Ted was talking about a way to perform online ext3 filesystem checks. I can't find any information on it by googling, is it implemented in current versions of the filesystem utilities? Either way, does anyone know where I can find more information on it? -- Regards, Oliver Hookins Anchor Systems

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... #tc qdisc

Hello, I use HTB with linux-2.4.20-ac1 and iptables-1.2.7a (pathced for IMQ). I configured one HTB qdisc on an IMQ device. This qdisc has some classes (about 5) and all of the classes has qdisc pfifo. I sometimes got out from my linux (while I was working) and I found in logs: Dec 4 11:49:27 core kernel: HTB init, kernel part version 3.7 Dec 4 11:49:28 core kernel: HTB: quantum of class

Hi all! I just started to experiment with bandwidth management using tbf. I have the folowing problems with token understanding: 1) What unit is token? Is "1 token = 1 byte" ? If this is so, then with rate=0.5mbit and HZ=100 the bucket gets filled with 0,64kb (655 tokens) every 10ms? 2) How much tokens are used for one packet (1500)? 3) And token unrelated question. Does

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

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

Hi All, I am using the script below to limit download rates and manage traffic for a certain IP address and testing the results using iperf. The rate that iperf reports is much higher than the rate I have configured for the HTB qdisc. It''s probably just some newbie trap that''s messing things up but I''m buggered if I can see it. The following script is run on the

Hello list, I need to realize a complicated custom shaping setup, and given very little experience with shaping I just can''t wrap my head around it. I am not seeking a complete script, I just need an idea/a set of pointers on how to best subdivide traffic accordingly to my needs, and which shapers to place on every leaf. I am very experienced with netfilter and have minor experience with

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

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 for tc because was going to try to add additional

Hello, 1. I currently have a 128kbps cable link to the internet..and I''m sharing this connection with others. I''ve made the following script(for alocating bandwidth depending on the services used: browsing, squid, games like counter-strike, icmp, ssh), which unfortunately isn''t working very well as the response times I''m getting upon pinging the server

I know there is that handy patch available to very efficiently use ATM bandwidth, but I was wondering what the best values to use with a non-patched iproute2 would be. Anyone here care to check my logic in coming up with these numbers and perhaps suggest better values? My transmit speed is 768kbps per ADSL line (I have two). This is the HTB shaping I do on the interface (logic used for this

Hi. I wrote in a reply to a mail on here recently that you can''t set mpu (minimum packet unit) on HTB as you can on CBQ. I''ve just noticed that there is a patch on devik''s site which does mpu and overhead. http://luxik.cdi.cz/~devik/qos/htb/ For dsl users mpu is, for practical purposes going to be 106 - overhead is still variable though, depending on packet size.
