Hello, I just found the great howto and started shaping my internet connection. The howto''s last update is a liitle in the past now so I have some questions about how things are done the best way nowadays ;-) To ensure a stable and low latency voip communication I added an HFSC qdisc to device ppp0 (1 Mbit SDSL). There are two classes (by now): One for SIP and RTP and one for the

G''Day I would like to be able to use my VOIP telephone over a saturated ADSL link whilst enjoying optimum audio quality and utilising all of the bandwidth I pay for. It is about this situation that I write. HFSC appears to be the queueing discipline of choice for VOIP. In order for this to work, though, do I have to account for the ATM overhead in the small VOIP packets by defining my

Dear all, I''m now developing the qos mechanism on my mechine. I have read the documents of both the web site "HTB Home" and "lartc.org". But it confuses me that what is the accurate definition of the argument "rate"? It seems to be "the minimum rate which is guaranteed for a class" in the user guide of HTB Home, but in the manpage of lartc.org

Hi all, I am wondering if anyone can help me to resolve a problem. I am trying to use tc command in linux to drop udp packets of specific diffserv value. I am able set diffserv value successfully in the udp packet using command:- [root@scotch src]#iptables --table mangle --append OUTPUT \ --out-interface eth0 --protocol udp --source-port 5060 \ --jump DSCP --set-dscp 8 but i am not able to

Hello all, I am trying to set up a simple htb based system, where packets with source ip 10.0.0.1 should have their own class. I plan to use tcng to set it up easier. Is there something wrong in my tcng file ? ~/tcng$ cat htb /* */ #include "fields.tc" #include "ports.tc" dev eth0 { htb ( ) { class ( rate 600kbps, ceil 600kbps ) {

Hi I''m completely stuck with the tcng language - I assume there must be some way to arrange queues hierachically like eth1 | TBF | PRIO / \ class class but my attempt (below) produces a "inferno.tc:8: qdisc "tbf" has no classes near "prio"" when run through tcc. dev eth1 { egress { tbf (rate 128kbps, burst 64kb,

Hello every one! I''m making a project to a discipline in the university and the project is make a Linux router that grants QoS to Multimedia connections (the prof. say we can use Open Source Soft. :) or reinvent the wheel). I have been googeling and googeling and i found the l7-filter in source forge and the spectacular simple language that is TCNG. Well the problem is how can i

Dear List, I am wanting to perform some traffic shaping as the subject of this email suggests. What I am wanting to do is this; I would like to have traffic shaping performed on the following protocols: HTTP, RDP, GRE, PPTP, SIP and IAX. Obviously I would like to have highest priority set for voice packets so much so that the general http traffic does not impede on the voice packets. I

Hi all, Can someone say me the theoretic way of packet in the kernel. When the packet will be send to a IMQ device? When the packet arrives to post routing time? When operation of NAT occur? befor or later that the packet will send to net device?

Dear all, I have 3 backbones for my local network. 1st backbone: down 1024kbps, up 1024kbps through eth1 2nd backbone: down 2048kbps, up 2048kbps through eth2 3rd backbone: down 1024kbps, up 128kbps through eth3 Local network: 192.168.0.0/16 through eth0 Router: Linux Slakware 11 with iproute2 Please let me know how to shape both incoming and outgoing traffic for this case. LARTC doc only

Hi all, It is my understanding that with HTB, the rate and the ceiling are divided over the elements of the class. E.g. using a rate of 100 kb and a ceiling of 2000 kb for a class with 10 elements on a 100Mb NIC, the effect of the ceiling will be that if all elements are generating their maximimum possible trafic they will be effectively limited to ~ ceiling / number of elements, in this case

Hi all, this is really not really very easy to understand, or, to get in. Well, I''ve the following configuration on the router box: LAN - interface: eth0 - network: 192.168.2.5/24 - bandwidth: 100Mbit/s INET interface - interface: ppp0 - network: .dynamic.ip./0 - bandwidth: DOWN=1536kbit/s and UP=256kbit/s the LAN interface is to serve 6 other clients with internet and

Hi all, I''ve done a search through the archives but I can''t find a cause/solution to this. I''m running a FC4 box with the stock 2.6.12 kernel and a FC2 box with a stock 2.6.9 kernel. I''m obviously using iproute2 and the patched tc. When I clear down the qdiscs with "tc qdisc del dev <DEV> root" I get the following in response to "tc

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

Greetings routing folks, I want to use the netmask 255.255.255.255 to insulate (not quite isolate) machines on a shared subnet from each other. This works just fine on win XP, but Linux iproute will not acccept the gateway address in one step -- neither on the command line nor via DHCP: Here''s the interface, set up with a netmask of /32: # ip addr ... 2: eth0:

//Just to not forget eth0 is WAN and eth1 is LAN . The box is NATing my lan. I configured tcng to shape both download and upload and i got connection loss again. Maybe it is my script fault or it is something bad with packets marking . this is how i mark outgoing packets iptables -t mangle -A MYSHAPER-OUT -p tcp -s 192.168.1.23 -j MARK --set-mark $ip and this part of my script which is intented

I''m trying to do some very simple rate-shaping on an interface. I want to limit my 100baseT interface to 7 megs both ingress and egress of the interface. I''ve been hacking my way through the documentation and some examples and I''ve come up with the following configuration for tcng that seems to do what I want. I''m curious if some of the other experts out

hi all. i am currently now serving PPPoE in my area. i had a script generated from tcng that worked perfectly before i started serving PPPoE. the issue is not in the script it self BUT in that "tc" code is not shaping on the ethernet anymore BUT INSTEAD on the pppX devices. I tested it and talking jargon, what should i do? The issue is that for each PPPoE login, PPPoE-server

I have a Gentoo Linux (kernel 2.6.11) server. Several months ago, I made a traffic shaping setup for my box (running a 2.4 kernel then) that worked beautifully. It gave high priority to SSH and RealAudio traffic, and put HTTP downloading traffic on a lower prio so they could only use what bandwidth was left. However, I''ve only just realized that tc is no longer accepting the commands I
