similar to: Error rate control on queues

Hi, I implemented queues on some ports with htb by filtering. and to have a constant bw, i defined rate and ceil the same. But while watching the bw''s, I ve realized they may sometimes exceed the defined value for short periods. How could I avoid this situation? I thought that implementing a leaky bucket''d be fine but i m not sure about this and how to do it on tc. I would be

Hi, I am trying to control bandwidths of the connections by using TC with HTB. But I want to implement Leaky Bucket on this structure so as to have a straight flow. Due to being new in this area, could anyone help me how I could do this? Does TC support leaky bucket? Best regards, Fatih Duzova

Hi, I ve implemented htb queues for some ports on my computer by filtering. when creating queues at very first, i defined rate and ceil values (and made them equal to have a constant bw). How can i change dynamically after this, to increase or decrease bw then? Is there any way to do this? I would be glad, if anyone could help me.. Fatih DUZOVA

hello, I am trying to find where filtering is done in order to drop packets randomly there (eg.10%of them) for a testing purpose in a school project. I want to do this after packet is filtered and before being sent. I d aprreciate if you could help or suggest. Thanks.

Hello, For a test purpose, I want to drop tokens with determined probabilities in an HTB structure. But I do not know how I could do this, in fact due to being newbie. I d appreciate if anyone could help and suggest sth. Thanks, FDuzova

Hi, I need the source code of tc-traffic controller tool, but due to being new here, I could not find it. And also I should know whether I can implement leaky bucket with tc. I would be grateful, if anybody could help me.. Fatih Duzova

Hello all, I have browsed archives and real all available HOWTOs, but I still have a few doubts. My set up is a router, as below. LAN(100MB)-------------(eth1)Linux-Router(eth0)---------------WAN(2MB/512) My aim is to cotrol both uplink and downlink bandwidth. For uplink control, I will use HTB on WAN interface. For downlink, I plan to attach HTB on LAN interface(both egress/outgoing). No

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 First thanks for the answers I have received from the list!! I have now a working qos configuration which bases of the lartc howto capitel 15.10. One Problem I have is that I have limited the upload stream to 100kps because my upstream is only 128kbps. Everything works fine EXCEPT Voip. I have a VoiP phone which is connected on the same net as the adsl modem BUT does not use upstream it

Hi, I have a cable modem with a bandwidth capped upload rate. I''d like to prioritize packets going outbound according to the TOS header of the IP field. I''ve read through the LARTC Howto several times, and I think I have a good feel for the information it it. It also seems that what I''m trying to do is pretty straight-forward and common. Unfortunately, the HOWTO

Hello, I''m trying to setup what I thought would be a fairly basic tiered shaping system. I have a 6mbit (768kbps) link coming into my eth1 device, with my LAN IPs on the eth0 device. I want to limit outgoing traffic so that certain IPs are limited to 400kbps, with 3 classes under that 400k so certain machines get prioritized (main servers in 1:21, other servers in 1:22, workstations

Hi, I have a small question about tc''s source code. I m trying to compile the code by itself, and for this purpose i ve created a big .c file that includes all the sources it uses. the reason behind this to make a small modification for my school project. But whenever I try to do "tc qdisc add ..." or "tc class add..", it gives the error segmentation fault, and it

Hi all, I am running Slackware 10.1 with Kernel 2.6.14.3 includes iptables 1.3.4 with layer 7 My network diagram below: - INTERNET --- LINUX_ROUTER_FW --- PCs Below is my simple iptables script: - echo 1 > /proc/sys/net/ipv4/ip_forward iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE iptables -t mangle -A POSTROUTING -m layer7 --l7proto applejuice -j MARK --set-mark 1 iptables -t

Hello! I am using shapping whith htb. My question is what are the propper values I can use in rate/ceil. I use htb.init for quick building of my classes/rules and have 2 groups of clients with 2 different bandwidth assignemet : A. 16--->48kbps B. 16---->128Kbps It seems to work everything OK, but can I use lower values for rate like 8Kbps ? What about using 32-->96Kbps? I let htb to

Hello again, First, excuse me for my poor english. I''m trying now to make bandwith control in a firewall machine running Shorewall. This machine is also a bridge using bridge-utils bridge-utils-devel. It is a mandrake 10. The configuration is something like this: FTP/Webserver ------| eth0 eth1 Mailserver

Hello all, when running tc -s -d class show dev eth, the parent class rate and ceil are different to the configuration? his is the first time I have used HTB so I may have made some basic mistakes. Thanks in advance Shaun Output as follows: class htb 1:1 root rate 760Mbit ceil 760Mbit burst 997641b/8 mpu 0b cburst 997641b/8 mpu 0b level 7 Sent 0 bytes 0 pkts (dropped 0, overlimits 0)

Hi, I''m trying to get HTB working correctly on Centos4 (RHEL-based) with kernel 2.6.9-34.EL. I have two gigabit network interfaces bridged together and I have created the following: tc qdisc add dev eth2 root handle 1: htb default 1 r2q 8000 tc class add dev eth2 parent 1: classid 1:1 htb rate 100Mbit burst 24k cburst 24k (I have been trying different parameters). The network is

Hello, i have a htb setup where the root and (nearly) all child classes has a ceil rate with max up from my adsl line. But the root class don''t reach the ceil value but some childs are get a huge backlog. My setup: (tc -d class show dev ppp0) [cleaned a bit] ******************************************************** class htb 1:1 root rate 576000bit ceil 576000bit burst 30Kb/8 cburst

Hello everyone, First of all, sorry for my poor english. I''ve been working with this for a few weeks and I''m getting sick... I''m trying to control the bandwith in my network using the following script. The machine where the script is running makes NAT, eth0 is connected to the router and eth1 is connected to the Lan. When I run the script it doesn''t appear any
