Hello.. I have a linux box and I want to make priority on traffic generated by my LAN''s computers.. I don''t have a guaranted bandwidth, so I wanna use sfq... I want to make traffic to port 80 , 443 , 25 & 110 PRIORITY 1 Traffic src or dest 192.168.0.2 to make priority 2 And the rest to put it in proiority 3.. I did the following : tc qdisc add dev eth0 root handle 1:

I think that there are no qdiscs that permit to drop the oldest frame of a queue when this queue is full, but I would like to be wrong: bfifo drops arriving frames when the max queue length is reached. red also drops arriving frames in a more elaborate fashion, with a drop probability that increases above a limit and becomes a drop certitude when the max queue length is reached. sfq drops "fairly", it piles frames with same...

EHLO tc gurus. New to traffic control. Unfortunately, the politicians here in Denmark have decided that a PC is the same as a television set - so anyone owning a PC and internet connection of over 255 kbit/s must pay DKR 2200/year = EUR 300 = USD 400 in television licence fees :-( This is a lot of money for poor students, so we want to offer the students the *option* of limiting their

I ''ve been trynig for a long time now to make HTB and GRED to work togethen. The problem beeing that GRED doesn''t use handles (instead it uses DP:1 DP:2 etc) i can not preperly filter traffic to them. Tomas Graf suggested to use the tc_index index of u32 classifier so dear Sant .. i am currently with the following scripts that works! But when i try to add an HTB before the

Hi, there is something I''m not able to understand about HTB statistics. Why the qdisc show show how many packets are overlimits but in the classes there are always 0 packets overlimits or dropped? I try to expain with a simple example. I create a qdisc htb with only a class and then i do a lot of traffic. pc-innocenti:~# tc qdisc add dev eth0 parent root handle 1: htb default 10

Hello all, I am running a coop satellite link for my aviation company here in Iraq. (silly blog www.stardotstar.org). I am running tc with htb with good success so far. I am working on improving it though and need some help. Currently I have just 4 classes, syn/ack/ping, webchat, http, and then other. We are really happy with how this has improved our ability to call home from our rooms and

Hello Lartc''s users, This is my first contact. I''m trying to implement a new queue discipline based on bfifo schedule. I search on internet but there are some problem(s) that I don''t Know how to solve them and that''s why I''m here asking for your help. Well, These were my steps for the implementation: - Put the new qdisc routine "sch_ric.c" into the directory "...

Greetings -- in the "Linux Advanced Routing & Traffic Control HOWTO" chapter 14.1 on bfifo/pfifo it says that: "you can use this qdisc to determine the backlog on your interface". But it does not say exactly how. Command [#tc -s qdisc ls] outputs the number of packets sent so far but it does not output any info about the backlog. My first question is whether a command exists...

Anyone notices that using sfq qdisc adds latency compared to pfifo? With "sfq perturb 10" ping latency is around 100-120ms, while with "pfifo limit 3" drops to ~10-30ms (qdiscs belong to htb class). I''m missing something or is this expected? { $TC_CLASS parent 1:1 classid 1:20 htb prio 0 rate 900kbit ceil 1000kbit burst 7k $TC_QDISC parent 1:20 handle 200: {pfifo

In 2.4 kernels, there was a [bp]fifo that could be implemented with ''tc add'', but in 2.6 kernels, I find no way to create either of these fifos. I am able to increase txqueuelen. What I desire is a larger number of backlogged packetes before drops occur. How can the output buffer size be increased for HTB? -- gypsy

Hi, I am new to tc and have been reading quite a bit on how to set it up etc. Everything seems to be working fine, until I started scp-ing a large file over a low bandwidth connection as part of my testing process. Here is the setup: my pc --- bridge running tc/htb --- rest of network TC is filtering traffic from "my pc" and classifies it as 120kbit (see my script below). I then scp a

Hey all, I recently read on a prior post as well as the FAQ that packets can be limited by mac address using the u32 filter. I attempted this and, while all the commands went through with no errors, it is not limiting at all. I''m attempting to limit all IP traffic to a specific destination mac address (00:12:3f:05:43:7f). Here is a quick rundown of the commands

...he Internet things are just fine. I gets bandwidth upto its rate (which is the same as its ceil). However as soon as another host joins the download party the first host''s bandwidth starts dropping until it ends up somewhere in the vicinity of 1/3 of its rate. I''ve tried pfifo, bfifo, no leaf at all and SFQ, all of which demonstrate the same behaviour. There''s no lack of bandwidth on the VSAT end, so this behaviour is completely inexplicable. Sharing of bandwidth between hosts within a class is working just fine. Using the iptables mark facility to classify the pack...
