similar to: dropped bytes in "tc -s class" output

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

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, 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, 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

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

Hi All Can someone tell me what am I doing wrong? These was suposed to catch icmp type 8. Why ''match u8'' does not work? # tc filter add dev eth0 protocol ip parent 1: prio 2 \ u32 \ match u16 0x0800 0xffff at -2 \ match u8 8 0xff at 20 \ flowid 1:5 Illegal "match" # # tc filter add dev eth0 protocol ip parent 1: prio 2 \ u32 \ match

An earlier exchange about someone seeing the rate larger than the ceiling is posted below. Andy explained the reason for the "above ceiling" rate in Daniel''s output . . . but I just saw an example that doesn''t fit. >> tc output >> class htb 1:14 parent 1:1 leaf 14: prio 1 quantum 3072 rate 256000bit ceil 282000bit burst 1820b/8 mpu 0b overhead 0b

Hello, I''m using tc to limit the bandwidth of our wireless customers. I have a working script, but I''m not happy with it. I''m trying to write a more sophisticated script, but when I run it, it give me this error: RTNETLINK answers: File exists I have no idea what this error means or how to fix it. Here is a portion of the script (the whole script shapes several

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

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 to all of you!!! I am a Computer Science 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 ...

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. 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

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?

What''s going on here? I''m spewing UDP traffic at this thing, and it is exceeding the ceil.

Hello I have 2 strange errors when using the Background()-application and DTMF-input that is received. First of all, my first 2 lines are not being executed. The first line being executed is the Set() application, thus line 3. Secondly, the received digits (911) is not the same as the EXTEN (which is set to 91). exten => ivr,n,Set(TIMEOUT(digit)=2) exten =>

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 I am fighting this for 3 days and could not find any reason it is not working the way I want to (or I the way think it should).
