Hi all, my IMQ device works OK (thanks to Andy Furniss), but now I''ve problems to attach the traffic in the qdisc''s. This is my conf: ----------------------------------------------------------------------- INET | |eth0 300Kbps ROUTER (NAT) |eth1 | LAN ----------------------------------------------------------------------- MAX=300 tc qdisc add dev imq0 root handle 1: htb

Hi, The CBQ config file shud be some thing like this. DEVICE=eth0,10Mbit,1Mbit RATE=50Kbit WEIGHT=5Kbit Shall i hardcode the DEVICE BW as 10/100 Mbit or Shall i use any other tool like ethtool for getting this. ethtool gives Speed: 10Mbps If so, how about, if i use some other Interfaces other than eth0, like ppp0 or some other? C''d anybody can give a suggestion over this? thanks

Hello, I have begun to use the tc scripts since 2 weeks ago, so I am beginner. I am trying to divide my bandwidth in 4 independent ones. Each of these sub-bandwidths is assigned to 4 different groups of ip. Bandwidth sharing is allowed. I put a Linux with two Ethernet card between the router and the LAN. Eth1 is the card connected to the router and eth0 is the one connected to the LAN. My ISP

I am trying to do ingress flow control with htb + imq, and as could be expected it isn''t working well. It works a lot better when I keep the htb ceiling well below what the link can actually carry - I guess because htb gets to throttle the TCP fast start before it causes packets to be dropped. The only problem is wasting all that bandwidth hurts. It occurred to me that the bandwidth

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, I''m trying to configure several wireless routers with QoS support. The idea is to implement differentiated services so that VoIP traffic gets the maximal priority, then video, control traffic, interactive data traffic and best-effort traffic. I have seen that CBQ used to be chosen as qdisc for implementing bandwith share in DiffServ but now HTB is preferred because it is

Hi folks, I`ve a problem to use HTB and SFQ. The first script, below, to show a simple configuration, does work fine...!!! But, in the second example, does not work, becouse i put more code to clasify the traffic by protocol, http and ftp in this case. Somebody can tell me the errors? Thx, in advance.- NOTICE: IMQ device is to asociate with ETH1 my external iface. SCRIPT que funciona:

I have voip quality issues I would like to minimize. I have a ~= 3M/384k (Comcast) cable modem and a CentOS based Linux router (SME 7, 2.6.9 kernel) with 5 NAT''d devices (3 PCs "DHCP", 2 Vonage adapters "static 10.10.2.10-11"). The quality problems are audio cutting out and popping. I tried the following (see below) based on a Cookbook example, but I still have

Hi! I recently changed my qdisc from CBQ and PRIO to only HTB, and I can''t really seem to get the rates to work as I want them to. I have eight classes, which I set up as follows: tc qdisc add dev eth1 root handle 1: htb default 122 tc class add dev eth1 parent 1: classid 1:1 htb rate 1000kbit ceil 1000kbit cburst 1500 burst 50kb tc class add dev eth1 parent 1:1 classid 1:11 htb prio 0

Hello! I have a quite complicated setup. In my network on each interface there is bandwidth limitation for each user. Booth outgoing (on interface itself) and incoming (attached IMQ) traffic. There is main HTB class which limits bandwidth for whole interface and HTB subclasses for each user. Filtering is done with hashing filters. This setup was working correctly. But now in the network I

Hello, I have recently started looking at tc and iptables. I have an htb-queue with two classes 1:10 and 1:20 where 1:20 is the default. Then I use iptables to mark all packets I send out on eth1. I then filter marked packets into class 1:10. I expected all packets sent on eth1 to end up in class 1:10, but some packets still go to 1:20. Did I do it wrong? Thank you for any help. regards, David

Hello At first I must tell you that I´m a real newbie with Linux (and english as well...) I´m using 2 vlans and shaping works quite well without vlan Now I want to do load balancing at these vlans. Any vlan should get the same minimum/maximum bandwidth of download and use the bandwidth that isn´t used by the other one at the moment. But with vlan the shaping doesn´t work. Can you please tell me

I try to use tc on mips with linux-2.4.18 but the u32 filter dosn''t work I added htb qdisc to linux-2.4.18 and use it to limit the speed in LAN, it only work well on the default class, for example tc qdisc add dev eth0 root handle 1: htb default 10 tc class add dev eth0 parent 1:0 classid 1:1 htb rate 2000kbit tc class add dev eth0 parent 1:1 classid 1:10 htb rate 500kbit ceil 500kbit

Hi, Thanks for the reply. Thats where the problem starts. If I set ppp0 as the default gw the internet doesnt work anymore. This is how im doing it... route del default route add default gw 217.32.81.74 dev ppp0 if I put it back to ppp1... route del default route add default gw 217.32.68.73 dev ppp1 It works fine again. Whats up with that? Cheers, Chris ----- Original Message

Hello, I use rrdtool to graph the traffic in the different classes on an interface, eth1. Basically, I use the output from tc -s qdisc ls dev eth1 my tc script (which is only for testing the graphing) looks like this: /sbin/tc qdisc add dev eth1 root handle 1: htb default 20 r2q 1 /sbin/tc class add dev eth1 parent 1: classid 1:1 htb rate 200kbit burst 15k /sbin/tc class add dev eth1 parent

Dear All! I reach the point that I must ask you what I have to do. I am beginner at traffic shaping and I''m very confused with it. :) Here''s my script that doesn''t do what I want to do with it: tc qdisc del dev eth1 root tc qdisc add dev eth1 root handle 1 htb default 2 r2q 10 tc class add dev eth1 parent 1: classid 1:1 htb rate 300kbit tc class add dev eth1 parent 1:

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
