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

I''m not an expert, but I can tell you that when traffic shaping on a router, you can just shape egress both ways and not mess with imq. My script is at http://www.stardotstar.org/?page_id=63 The basis are the following 2 lines where UPDEV is ppp0 and DOWNDEV is eth0 in your case. tc qdisc add dev ${UPDEV} root handle 1: htb default 100 r2q 1 tc qdisc add dev ${DOWNDEV} root handle 1:

Hi list... I work for a school in the netherlands with a 2mbit Internet uplink and about 3800 eager student who want to play games on the Internet using one of our 800 workstations. Problem was that those game playing students are concentrated in 2 of our 6 physical locations... and they consumed the bandwidth which the other location would like to use for educational purposes. The thing we did

Hi there, a program is downloading large files on a regular basis and has no switch to limit bandwidth. Is there a way to shape this incoming traffic? Any pointers? My outgoing traffic shaping works perfectly, but this incoming thing gives me a headache.. many thanks in advance! Dominik

Hi all, I have an average 2mbit multicast stream that once in a while bursts high (up to 20mbit/s) in short periods (about 200ms). Could anyone please help me with directions using tc for configuing leaky bucket shaping to this stream? I have a 5mbit/s ceiling. My system is running gentoo linux 2.6.14, and I have compiled in all QoS modules. Thanks. Oivind

I''m just-so-fresh to the list, so hello everyone. I''m having a realy hard time with setting up very simple bandwidth management. What I am trying to do is setup a 10Mbit interface to send at only 1920kbit to most of the network (to make sure it hardly ever tops 2mbit). I did succeed with the ingress traffic... With egress however, I get very odd results at different speeds. With

Hi Here is something that worked with with 2.6.10-1.771_FC2smp and stopped working when I upgraded to 2.6.16-1.2069_FC4smp. These are fedora kernels and the network controller is an Intel Gbit (e1000) running a 100 Mbps Full Duplex. Don''t know how or if this matters but the 2.6.10 kernel has CONFIG_X86_HZ=1000 and the 2.6.16 has CONFIG_HZ=250 The idea is to just shape to , say 2Mbit, a

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

Hi all Its been long time i have sending this message to this news group but i could not get proper responce from the authors or any experts that, is that bug or only the problem with my ssytem iam tryin this config with FC iptable 1.3.0 and latest TC tc utility, iproute2-ss050330 htb 3.17 iam trying past 2 weeks and digging all googles but could not able to come to conclusion whats wrong

Hi. there is a way to MARK udp VOIP (SIP) traffic, in order to put in a highest prio class ? Traffic flow seems start on udp 5060 port, but next both server and client seems jump to a random(?) port. I can''t use CONNMARK because is udp traffic. I only see a pattern for L7 patch in order to SIP traffic identification , but I run 2.4 kernel series . When you patch 2.4 kernel with

Hi Couple months ago I started to have a strange problem with HTB. My setup is Fedora Core 2 + Pentium 2 233 + 128 MB of ram and its serving as a router. For some time since going to kernel 2.6 my HTB QoS Stalls for couple seconds, every couple minutes. If the connection load is bigger the stalling is more frequent and takes longer. I isolated the problem to be with HTB (CBQ works fine). The

Folks, I am a little bit confuse in how to put these packets into correct mangle table for traffic shaping. This is what i ve planned to do: - - - - :eth0 [ LINUX-BOX ] eth1: - - - - Let say: eth0: 220.100.1.1 eth1: 192.168.1.1 eth1:1 192.168.1.2 192.168.1.0/24 get natted into 220.100.1.1 before reaching the internet. I put every packets coming from internet (eth0) this way: # iptables -t

Hello, Stephen, List! Attached is the patch for iproute2 to add the possibility to use fwmark in u32 filters. The kernel part was included in 2.6.10. Please apply! Thank you! For more info: - Kernel patch (not needed for 2.6.10): http://kernel.umbrella.ro/net/mark_in_u32/net-match-nfmark-in-u32.patch - Examples: http://kernel.umbrella.ro/net/mark_in_u32/examples.txt --- Catalin(ux aka Dino)

Hi, One of my customer needs per flow rate control, so I write one. The code I post here is not finished, but it seems to work as expected. The kernel patch is agains kernel 2.6.11, the iproute2 patch is against iproute2-2.6.11-050314. I write the code in a hurry to meet deadline. There are many other things to do ahead for me. The code is written in 2 days (including read other

Hi again, I keep posting about my problem with HTB -> http://mailman.ds9a.nl/pipermail/lartc/2005q3/016611.html With a bit of search I recently found the exact same problem I have in the 2004 archives with some graphs that explain it far better than I did -> http://mailman.ds9a.nl/pipermail/lartc/2004q4/014519.html and http://mailman.ds9a.nl/pipermail/lartc/2004q4/014568.html

Hello List, I''m new to QoS/tcng/HTB and friends, so please forgive me if my question might be silly... After having read lots of HowTo documents I''m totally confused... The Challenge: ============== I''ll have to deploy several "mirror" download servers (Linux) which must be able to handle a huge number of HTTP download requests (about 10k to 20k unicast

Hi I''m using wondershaper like script. But noticed imperfect scheduling. By googling, I found some patches that takes the aal5 atm overhead in the scheduling algorithms. http://www.adsl-optimizer.dk/ADSL-optimizer/ Before trying it, has anyone tried these patches? they apply on 2.4.29 kernel and 2.6.9 TC. I use centos4 with a 2.6 kernel, so I can''t try these easily. Thanks

Hi everyone. I''m new to this list and I have some questions regarding HTB class. I was trying to see how tc sets the parameters for HTB, but really couldnt understand them. So, I thought that I might ask the wizards. It''s mainly from the source code. 1. What is the cell_log ? (its everywhere in the code) 2. Why does htb calculate its burst(buffer) with tc_xmit_time() ? Is
