Dear All, I''m using the kernel 2.6.6, iproute2-2.4.7.20020116, iptables v1.2.9, and gentoo. I have a leased-line 64 kbps. I can see the counter works in iptables, but in the htb, it doesn''t go to the right class (it always go to the default class). Any help will be appreciated here''s my htb conf #!/bin/bash tc qdisc del dev eth1 root tc qdisc add dev eth1 root

Dear all, I''m having real problems getting tc to do anything useful at all. I''m also under pressure to get this fixed before the students start arriving later this month (I work in a university). In short, I want each IP address to be hard limited to 128kbit down, 64kbit up, never to be allowed more bandwidth than this. It is also important that the latency remains

Hi! I''m trying to limit the uplink bandwidth using htb but no packets are overlimit or dropped. :-( My router config: * Linux kernel 2.4.20-pre10 (htb v3.7) with everything built as modules in QoS, iptables in use. * tc binary from htb3.6-020525.tgz * external interface eth0: Internet access, 512 kbit/s uplink speed * internal interface eth1: internal LAN, 100 Mbit/s The hosts in the

Hello, I use HTB with linux-2.4.20-ac1 and iptables-1.2.7a (pathced for IMQ). I configured one HTB qdisc on an IMQ device. This qdisc has some classes (about 5) and all of the classes has qdisc pfifo. I sometimes got out from my linux (while I was working) and I found in logs: Dec 4 11:49:27 core kernel: HTB init, kernel part version 3.7 Dec 4 11:49:28 core kernel: HTB: quantum of class

Hi, I''m trying to perform some (what I consider) basic traffic shaping on our network utilising HTB. I have mostly reused the example on the lartc.org site: tc qdisc add dev eth0 root handle 1: htb default 10 tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbit burst 24k tc class add dev eth0 parent 1:1 classid 1:10 htb rate 50mbit ceil 80mbit burst 19k tc class add dev eth0

All, I have been using the following as a means of rate limiting access to the Internet via eth0 (which connects to my cable modem) and it was working great with my 2.4.20 kernel: tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 1 tc class add dev eth0 parent 1: classid 1:1 htb rate 486kbit ceil 486kbit tc qdisc add dev eth0 parent 1:1 handle 10: sfq perturb 10

Hi all, Can you tell me where is the documentation for the new IFB (implemented in kernels > 2.6.16). Thanks in advance! Nikolay

Hello! I need to switch from htb2 to htb3, because of speed issues (for me, htb2 is unable to handle more then 100mbit duplex with ~550 classes), kernel profiling shows htb_dequeue_prio at 1st place with 3x isolation. So, I''ve moved from 2.4.19 to 2.4.25 kernel (hi-pac for classification/marking and htb3 for queueing), and traffic rate drop from 100 to 20mbit. What can be wrong? The

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

Hi, I have a server and ten clients in a Gigabit network. The server has 125mbps network bandwidth. I want that the server has 40Mbps bandwidth reserved for client 1 (IP 192.168.5.141), and the rest bandwidth is for all other clients. My script looks like this (I use IFB for incoming traffic): #!/bin/bash export TC="/sbin/tc" $TC qdisc add dev ifb0 root handle 1: htb default 30

Hello, 1. I currently have a 128kbps cable link to the internet..and I''m sharing this connection with others. I''ve made the following script(for alocating bandwidth depending on the services used: browsing, squid, games like counter-strike, icmp, ssh), which unfortunately isn''t working very well as the response times I''m getting upon pinging the server

Eric, I''ve attached the output from the command you requested below. I''m using kernel 2.6.17.12 and tc version ss060323. I''m have a nforce4 onboard giggabit controller using the forcedeth driver, if that makes a difference. Charlie, I''ll take a look at the Apache model for throttling, thanks. I was going for tc because was going to try to add additional

Hi, I have implemented QOS classifiers using TC with HTB. The classification is working. I would like to know whether there is some tool which will help me in monitoring the bandwidth share of the various classes. Thanks, Vinod C

Hi everybody! I''m using an edge bridge box with two ethernet cards to shape traffic in a WAN link. I''m running Debian 3.1 stable with kernel 2.6.8 and iproute from packages. I recompiled the kernel with the following built-in options: [*] 802.1d Ethernet Bridging [*] QoS and/or fair queueing <*> HTB packet scheduler <*> SFQ queue [*] QoS support

I am trying to get IPP2P working on my router. Thus far I can see connections being marked (see below), but they don''t seem to get saved or something. When looking at /proc/net/ip_conntrack, nothing has anything other than 0 for mark. The iptables commands for this are: iptables -t mangle -A PREROUTING -j CONNMARK --restore-mark iptables -t mangle -A PREROUTING -m mark ! --mark 0 -j
