similar to: deleting tc rules

Hi I have been playing with tc. I''m using htb and sfq. I tried to setup shaping of every ip address within a /20. I found that there must be an upper limit of about 2096 on the number of rules (classes, qdiscs or filters). I was testing a /20 which gives 4096 classes, qdiscs and filters. I''m using hashkey to optimize processing of frames. When executing the script below - it

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there! Well, as an exercise, I try ''simulating'' an adsl link (just the speed ;o)) with a GRE tunnel and HTB for bandwidth limiting. Typically in germany adsl has about 1024kbit downstream and 128kbits upstream (yes, there are others ;) but these are what I have) - which are the values i try to simulate. Here is the snipped that

Since week i dig lists and www and can''t find solution for my problem. I''m using HTB 3.13 kernel 2-4-25 smp iptables 1.2.9.

Hi all ! I''m building a network appliance whose goals are to enhance Voip quality on 512/128k DSL links. But, i have a voice quality problem, and i think i''m doing something wrong, but i can''t find what. Please excuse my terrible english, i''m french. >From what i''ve read, tc is the tool i need. I read the documentations, readmes and lartc.org

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

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

With the below script, whenever I ping 10.0.16.10 (which matches the only filter I have), traffic still get''s sent to the default 1:2 class instead of 1:1 and I don''t know why... Any hints?

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

here is the situation i am using htb.init with fwmark to do QoS. i have 2 parent classes with RATE=CEIL which then have some leafs each on his own. the first one works fine (it shapes the packets to the specified rate) class htb 1:21 root rate 1Mbit ceil 1Mbit burst 2909b cburst 2909b Sent 631520262 bytes 651550 pkts (dropped 0, overlimits 0) rate 131573bps 141pps lended: 380595 borrowed: 0

Hello. I am wondering if the default (auto-computed) burst and cburst parameters are appropriate values for my application. I have a 100 mbit interface which is connected to a 16 mbit uplink. I am sharing this bandwidth into a set of partitions (tc classes) defined as follows: root class [1:1] |

Hi, I have a default class for my un-marked traffic (prio 5) and a prio 0 class for the important stuff, but I do not understand why my download traffic is duplicated in both. It work fine for my upload traffic (same setting except the red class but I have the same result if I create an esfq instead). Any comments/information will be appreciated. Below my config : tc commands from my scirpt :

I''m trying to shape traffic on a Devil-Linux box. This note was originally sent to their maillist, because the LARTC list appears to have been down for the past few days. My mailbox was just flooded with a half dozen or so confirmation requests in response to my repeated attempts to subscribe to this list. ---------- Forwarded message ---------- From: drew einhorn

Hi, I''m looking for a script in order to do traffic control on a ciber cafe LAN, with linux router. Ciber has about 40 hosts, and I haven''t much bandwidth (512kbit). Also, I''ve a squid cache and it works very good! I''ve found Jim QoS script, and FairNat. Which is more suitable for me ? Jim QoS ? FairNat ? other ? If I put FairNat, I would need ZPH patch

Hello, Besides a very good functionality, I have a small, yet stressing, problem. Let''s say I have a bandwidth of N bits. I have X clients, everyone with his fixed bandwidth. I create htb qdsics for each client. Each leaf has sfq queueing discipline. A sample config would be like this : tc class add dev eth0 parent 1:2 classid 1:346 htb rate 32Kbit ceil 32Kbit burst 4k

Hi, i am running imq + htb on my router , the situation is like this eth0 = uplink to my provider eth1 = 1st customer eth2 = 2nd customer eth3 = 3th customer eth0 has limit 512 and i want to share this between eth1 eth2 and eth3 , but not working , this is the script i used, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ #!/bin/sh

please, help, i have build vpn server (suse 9 + poptop), i have managed to implement tc htb in ip-up script, but every client has own ppp interface (ppp0, ppp1, ppp2...), and my idea is to share available bandwidth, not to limit connection, how to build root tc rule, when I have more then one interface?... please any one width experiance regards _______________________________________________
