similar to: Bandwidth shaping script appears to incorrectly halve the bandwidth

Hello! I have a problem here. I set up a Linux 2.4 machine to do bandwidth limiting for some of our customers. Current setup is something like this: |--------| backbone |-------| |---------| |Internet|225.1-----------225.10|limiter|228.1----228.10|cust. gw2| |--------| | eth0 |-------| eth1 |---------| | 225.20

I need to shape traffic from some IP on one LAN, but I''m in trouble. There is a linux 2.4.26 connected to the Internet (eth0) / LAN(eth1) doing NAT. I''m using VLANs in the LAN Interface, that is connected to a 3Com SuperStack II in a 802.1Q tagged port. I want to create a class that will limit the traffic at 384Kbit/s. I want to create two leaf classes that limit the traffic at

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

Did anyone ever answer this one?

Hi, I have been modifying the Wonder shaper to include another queue. My understanding was packets would be de queued to hardware in the following order: cbq1 -> sfq10 > sfq20 > sfq30. Also we only move onto the next queue when the preceding one is empty. However is seems to be prio xx number that reflects the order packets are de queued not to what flowid they belong to. If I

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

Hello everybody, I have a Linux router with an ethernet adapter and a ADSL device. My router has a GRE tunnel connected to a remote IP address. Using "tc" I have configured 3 different classes: 1. 290kbit rate (used for Voip Services) 2. 180kbit rate (used for GRE tunnel) 3. 80kbit rate (for generic data traffic) For each class, using "iperf", I send some data from a PC

Hello all, I''ve got a couple redundant (Spanning Tree Protocol) boxes running FC1 minimal install + bridge-utils and they are working great for QoS + ntop monitoring. I''m wondering if I should handle the VoIP traffic a little differently. I don''t mind letting VoIP and Video lend out traffic when it isn''t being used, so that''s why I gave them such

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

Hello all, I am having some trouble getting a firewall filter to work with TC. I am actually setting the mark via EBTables (which is working as far as I can tell, I am also logging the packet and my syslog reports lots of marks): ebtables -t broute -A BROUTING -p ipv4 -i eth1 -s 08:00:46:60:B3:57 -j mark --set-mark 7 --mark-target CONTINUE --log --log-level debug --log-prefix "EBFW Mark

hi all At last i got sucess !.. but am confused y it didnt work earlier..the difference today was that i reinstalled RH7.2 & complied kernel 2.4.16(not 17).. rest was same..... & the bandwidth too is under control!.. is it normal for to get more than said bandwidth--i mean i restricted a network with 8Kbit(with same script as below) but still was able to get a download(ftp) of

Hi! I just recently entered the wonderful world of the so called "advanced routing" and decided to try and limit the bandwidth of a MASQed network here and ended up in trouble :(. The setup is (as far as I can tell) pretty straightforward. eth0 is connected to the "real" network with a proper IP, and eth2 is 192.168.10.x (the MASQed network). All of it is basicly right out of

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

I have a setup where I have three NIC in a Debian box. I have eth1 conected to internet and eth0 NAT''ed to 192.168.1.1. eth1 and eth2 are bridged together, given ip 192.168.122.2. What I want to achieve is to perform traffic shaping on the bridge as well as prioritizing the traffic from eth0 very low. (This is from trental flat ...) However it seems that I am unable to perform thhe

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

Greetings, I have been reading the list for a little while now, but this is the first occasion I have had to post--of course, because of a problem. My problems began when I upgraded my RedHat 9 system to 2.6.10 from source. Aside from some other booting issues and things, all of which appear to be resolved, the only things NOT working are my scripts for traffic control. I get a whole host of

Hi, I have a question about CBQ and wonder if I can make a class that are guaranteed 2Mbit but can borrow excess bandwith and only to specific rate. In my exampel below I want to guarantee the network x.x.x.x/y 2Mbit and they can borrow up to MAX 4Mbit. I have tried to create subclasses but it only works like bounded or not. # tc qdisc add dev eth0 root handle 10: cbq bandwidth 10Mbit avpkt

Hi everybody, I have a network that only uses terminal services. Look at the diagram. 20 machines running WinXP <-> LinuxFW-1 <-> 1Mbit link dedicated fiber link <–> LinuxFW-2 <–> Terminal Server I’d like to give the maximum priority for bandwidth to terminal services (port 3389). I’ve changed the CBQ script from LARTC site to suite my needs, but every time I

Here''s the script. I would have posted it to a website, but I figure this''ll be better so it is always on the list for people in the future in case they wanted to see it. If you have any questions about any of it, please let me know. Mike and I aren''t the cleanest of programmers. Cron the script to run whenever you need it to. :) #!/usr/bin/perl # # TC Helper Script:

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
