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? (kernel 2.6.12, iproute2-2.6.15) tc qdisc del dev eth0 root > /dev/null 2>&1 tc qdisc add dev eth0 handle 1: root htb default 2 tc class add dev eth0 classid 1:1 parent 1: htb rate

Hi folks...!!! I need to generate qdisc statistics to show my 4 class (10, 20, 30, 40), i`ve all working with HTB and so on, but i need to graph this results e.gwith RRDTOOL. I found a script made in perl, that can to graph my 4 class, but i need to know which IP address on my LAN are using the bandwidth too, in other hand i need to classify the traffic by IP to show. This is an out of my

I have to match my packets based on MAC address, which I cannot do in the POSTROUTING chain, so I do it in PREROUTING using MARK. Then, I match on the MARK in the POSTROUTING chain to do a CLASSIFY. But this does not seem to work: wireless-r1 bwlimit # iptables -L -v -n -t mangle Chain PREROUTING (policy ACCEPT 3353K packets, 941M bytes) pkts bytes target prot opt in out source

Hi! Do you know somthing about hfsc and bps? There''s no output for speed only for packets. Doesn''t hfsc support such a field? tc -s class show dev eth0 class hfsc 1: root Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) rate 0bit 0pps backlog 0b 0p requeues 0 period 0 level 2 class hfsc 1:11 parent 1:1 sc m1 0bit d 18.0ms m2 1000Kbit ul m1 0bit d 0us m2

Hello, I have recently started looking at tc and iptables. I have an htb-queue with two classes 1:10 and 1:20 where 1:20 is the default. Then I use iptables to mark all packets I send out on eth1. I then filter marked packets into class 1:10. I expected all packets sent on eth1 to end up in class 1:10, but some packets still go to 1:20. Did I do it wrong? Thank you for any help. regards, David

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

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

Hi all, Can you tell me where is the documentation for the new IFB (implemented in kernels > 2.6.16). Thanks in advance! Nikolay

Hi all, First, let me say I''ve been most impressed with how quickly and professionally people on this list ask and answer questions. Next, let me say that with which I need help is properly configuring strict PQ, and gathering certain stats. Specifically: - I need to create a priority queue with four queues (let''s say they are of high, medium, normal, and low priority) - I

Hi folks. For quite a while, I tried to use linux (cbq and htb) to control bandwidth in order to replace a cisco equipment used to play this role on our network. After trying here and there, with a bunch of different distros, different versions, different compilations, ... the closest I could get was as follows: (using htb.init and cbq.init) Desired BW ==> Achieved BW 128k ==> 404.78

Dear Community, sorry for the somewhat dumb question. Maybe someone has any pointer to how to setup the RED queue to mark pakets with ECN. In particular what are appropriate parameter settings for limit, min, max, etc. All my trials end up with either "RTNETLINK answers: Invalid argument", although the command line (at least for me) looks fine in regard to what is said on the

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. Is

Dear all, I''m having real problems getting tc to do anything useful at all. I''m also under pressure to get this fixed before the students start arriving later this month (I work in a university). In short, I want each IP address to be hard limited to 128kbit down, 64kbit up, never to be allowed more bandwidth than this. It is also important that the latency remains

Hello. I have a linux server connected to a gigabit lan, and though that lan to a 768kbps/768kbps DSL modem. I''m trying to shape my webserver running on port 80/443 down to 512kbps, while leaving all other ports alone. The current configuration script that I''m using is as follows: tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 99 tc class add dev

Hi all. Since I move on to 2.6 kernel , filter ingress policy based on nfmark won´t work. Sorry for my english. Simple example: iptables -t mangle -I PREROUTING -j MARK --set-mark 1 ${QDISC_ADD} handle ffff: ingress ${FILTER_ADD} parent ffff: protocol ip prio 100 handle 1 fw \ police rate 128Kbit burst 10k drop flowid 2:11 # tc -s -d qdisc ls dev eth0 qdisc ingress ffff: ----------------

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

Hello I have few questions regarding tc functionality (qdiscs, classes, etc.) when vlans are in use. For example, consider interface eth0, for which I create and extra vlan with vconfig, let''s say eth0.11. Then using tc I can add usual things - qdiscs, filters, ... - to both eth0 and eth0.11. The questions are: - on which interface - virtual or real, should I actually use tc ? Or

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

Hi, all I''ve got problems with tc qdisc ingress. I''m using vanillia kernel 2.6.14.4 patched with http://www.ssi.bg/~ja/routes-2.6.14-12.diff, and iproute2-2.6.14-051107. i am using ingress to limit incoming traffic : (DEV is eth1 / DOWNLINK is 7700) # attach ingress policer: tc qdisc add dev $DEV handle ffff: ingress # filter *everything* to it (0.0.0.0/0), drop everything
