similar to: PRIO and CBQ

Hello everyone! I''m simply trying to put a PRIO inside an HTB (used to throttle). I''ve got interactive traffic on the network that I want to give priority (VoIP + Citrix + Video). I''ve used the filters in a CBQ script fine, but am having trouble adjusting them to this setup such that they properly assign the traffic. tc qdisc del root dev $e tc qdisc add dev $e

Hi everyone, This is on a linux box, ingress (eth1) at 100Mb/s and egress (eth0) at 10Mb/s. The purpose is to test CBQ Here is my script ------------------------------------------------------------------- # Root qdisc tc qdisc add dev eth0 root handle 1:0 cbq bandwidth 9Mbit \ avpkt 1000 cell 8 # Classes tc class add dev eth0 parent 1:0 classid 1:1 cbq bandwidth 9Mbit \ rate 5Mbit weight

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 ...

Hello, I''am successful using a linux (2.4.20) bridge and the cbq.init_v0.7 script for traffic shaping. But I can only use the queuing discipline tbf (LEAF=tbf). If I try use queuing discipline sfq or none then tc applies the rules but no shaping occurs. Is this problem a normal behavior when using bridging ? I tried to use htb.init (using patched tc binary). It accepts the rules but

Hi, In my LAN Iam trying to make following setup: - All the traffic generated by 10.0.2.1 should go to 10.0.2.11, If the destination of this traffic is internet than it should be placed on its interface eth1. Outgoing traffic on eth1 should be shaped.For this I am using fw filters and cbq. _______ 10.0.2.1 -------> 10.0.2.11(eth0 )----| A

Hello all. I''ve been struggling to QoS VoIP at our site and have a successful implementation at this point. Basically I had to set aside enough bandwidth for VoIP by placing all other traffic behind an HTB (multiple classes and queues behind it). Everything is fine. Here''s the diagram: ------- | eth | ------- | --------

Hello, I have problems setting up HTB. This is my setup : NET 1024/256 ADSL || eth1 Linux Firewall eth0 || LAN 10.a.a.a I want to GUARANTEE for an IP (10.x.y.z) a 800kbit bandwidth for HTTP download. But When 10.x.y.z does no HTTP download, other trafic must get the whole bandwidth, of course. The script I use (see below) is quite the same as presented at (the greeeeat page) :

I am using a server with asterisk and I am trying to prioritize voip traffick -- I am a newbie at this traffic shaping, so please bear with me. I used the script below and what happens is thatall traffic in the bulk class stops after a couple of minutes. Also, should I include the ports for rtp in the filter statements with the ports 5061 and 4569? Note I have a fairly big pipe -- supposed to

OK, finally I have made cbq run ! now I would like to know if it is posible to limit a range of IP to a speed. something like this : from 192.168.1.1 to 192.168.1.21 limit to 128K I don''t whant to limit each IP to 128K, what I would like to do is limit all 20 IP to have a max of 128K. Is it posible?

Hi, I have done this setup to give the machine 192.168.1.4 (masqueraded over dialup) the highest priority: #! /bin/bash WHAT="add" iptables -A PREROUTING -i eth0 -s 192.168.1.1 -t mangle -j MARK --set-mark 1 iptables -A PREROUTING -i eth0 -s 192.168.1.4 -t mangle -j MARK --set-mark 4 tc qdisc $WHAT dev ppp0 root handle 1: prio bands 3 priomap 0 1 2 tc qdisc $WHAT dev ppp0 parent 1:1

If I create a cbq qdisc as a leaf of a cbq class, the bandwith rate is the same of the root cbq qdisc or the rate of the cbq class? Does exist the parameter rate on the "tc qdisc add" for cbq command? tc qdisc add dev eth0 root handle 1:0 cbq bandwidth 10mbit avpkt 1000 cell 8 tc class add dev eth0 parent 1:0 classid 1:3 cbq bandwidth 10mbit rate 50kbit allot 1514 cell 8

Hi, I managed to fix 128kbit for an IP address of 192.168.200.3 as below: - tc qdisc add dev eth3 root handle 1: cbq avpkt 1000 bandwidth 100mbit tc class add dev eth3 parent 1: classid 1:1 cbq rate 128kbit allot 1500 prio 5 bounded isolated tc filter add dev eth3 parent 1: protocol ip prio 16 u32 match ip dst 192.168.200.3 flowid 1:1 tc qdisc add dev eth3 parent 1:1 sfq perturb 10 How can I

I''ve been following the HOWTO, and reading mailing list discussions about throttling bandwidth, and have had some success, but I just want to tie off some loose ends. Essentially what I am wanting to do is to keep our bandwidth usage below 1megabit, because if we go over we get charged for that traffic. I''ve used some of the examples from the HOWTO to limit our bandwidth, but I

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

The manual says (about prio): > Because it doesn''t actually shape, the same warning as for SFQ holds: > either use it only if your physical link is really full or wrap it > inside a classful qdisc that does shape. The latter holds for almost all > cable modems and DSL devices. I want to wrap prio inside of tbf. Here''s why: I have a server on a DSL line, which has

Hi all, I have installed 2.4.5 kernel, Debian Potato. my tc script: #!/bin/bash tc qdisc add dev eth1 root handle 20: cbq bandwidth 10Mbit avpkt 1000 echo root tc class add dev eth1 parent 20:0 classid 20:1 cbq bandwidth 10Mbit rate \ 10Mbit allot 1514 weight 1Mbit prio 8 maxburst 20 avpkt 1000 echo class tc class add dev eth1 parent 20:1 classid 20:100 cbq bandwidth 10Mbit rate \ 5Mbit allot

I run a small Linux webserver and NAT router from my cable modem at home. Whenever someone starts an http download, all other traffic from my LAN is starved. Bandwidth is not really an issue, but latency is particularly horrible -- pings that usually come back in 20ms can take up to 600ms while the web server is active! I set up QoS (netfilter+iproute2) on the NAT machine in an attempt to give

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 All, I''m using HTB to shape traffic, a little like this: tc qdisc add dev eth2 root handle 1:0 htb tc qdisc add dev eth3 root handle 1:0 htb tc filter add dev eth2 parent 1: protocol 0x8100 prio 5 u32 match u16 3000 0x0fff at 0 flowid 1:1 action ipt -j MARK --or-mark 0x01000000 tc filter add dev eth3 parent 1: protocol 0x8100 prio 5 u32 match u16 3000 0x0fff at 0 flowid 1:1 action

Hi, I wanted to implement some QOS on my Linux Box with HTB, but after some time spend on the configuration and tests, I still don''t manage to have some correct results. Here are the details : -ROOT 2000 kbits -HIGHPRIO SUBCLASS 50 kbits prio 0 -SUBCLASS1 750 kbits prio 1 -SERVICE1 250 kbits prio 1
