similar to: strange problem with 2.4.17 and htb

Hi, I''m new to HTB and CBQ, and i want to try it. But i failed the first step: load modules. I patch the kernel 2.4.17 succesfully, add QoS support, and all QoS scheds in modules instead off kernel. make clean dep bzImage modules modules_install copy the new kernel reboot fine But when i : server:~# insmod sch_htb Using /lib/modules/2.4.17/kernel/net/sched/sch_htb.o

Witold Szczerba spent his time evaluating fairness of borrowing. His troubles inspired me enough to analyze the problem: When a class changes from yellow to green it disconnects itself from parent''s feedlist. Unfortunately it resets feed pointer to the first child. I created a patch where the class uses classid to remember its position in the feedlist. The patch for 2.4.24 and hopefully

Hello, I think the BUG_TRAP() in the htb_dequeue_tree() is wrong. First it checks if the class pointer "cl" is NULL, which is obviously right. But I do not understand why we also check whenever the queue length of the leaf queue is zero "cl->un.leaf.q->q.qlen". I would have put that in the expression of the "if" statements that comes afterwards. A queue

I posted earlier when I noticed that htb was releasing packets in pairs, even though my burst/quantums were 1 pkt. To fix I set HTB_HYSTERESIS 0 in net/sched/sch_htb.c . This gives a noticable gain in upstream worst case latency, for me with 256kbit/s up I used to see +90 sometimes, now it''s +45. For the many who have 128 up it should limit them to +90 rather than +180. Andy.

Hi all, This may sound strange, but i have a question.. is there any commands which we can use to see the entire TC configurations.. iam new to this TC , thanks, Rajesh Rajesh Revuru, Res:105 smith lane,#33, Syracuse-NY 13210.

Hi. I wrote in a reply to a mail on here recently that you can''t set mpu (minimum packet unit) on HTB as you can on CBQ. I''ve just noticed that there is a patch on devik''s site which does mpu and overhead. http://luxik.cdi.cz/~devik/qos/htb/ For dsl users mpu is, for practical purposes going to be 106 - overhead is still variable though, depending on packet size.

hi, I have strange problems with HTB and several hundred classes flat structure i.e. root |--50kbps |--30kbps |--50kbps |--80kbps |--100kbps .... several hundred classes like this Ceil is the same as rate. The machine get no more than 2-3% average cpu(2.4Ghz pentium). What happens is that from time to time the traffic got "stalled". I tried numerous things to solve

Hi, for interested in participation on finishing new HTB developement I created simple docs regarding it. It is some insight into CBQ and HTB workings and problems. See luxik.cdi.cz/~devik/qos/htb/v3/

Hi, New to traffic shaping I would like to make some tests. It''s for a production server (fw), using 2.4.27 kernel. Something is not clear to me about HTB... is the last stable version included in the 2.4.27 kernel and iproute2 (iproute2-2.6.8-040823.tar.bz2) ? Are there special patches to apply ?

Help me  ... I try use the tc filter, but seems he doesn''t work, I already reconfigured my kernel ( 2.4.32 ) with all options related a QOS enabled ( like modules ) and nothing happens. I get the tc tool from HTB source package, well  this is my set : eth0 is my internal NIC. tc qdisc add dev eth0 root handle 1: htb default 12 tc class add dev eth0 parent 1: classid 1:1 htb rate

Hello there! Yesterday I started my experiments with HTB. I configured it this way: 1: root HTB qdisc | 1:1 HTB class rate 1000kbit | /-------+------\ 1:40 1:50 1:60 user1 user2 user3 rate 333 & ceil 1000 for everyone. User2 is disconnected and user1 and user3 are downloading. For all the time (t1-t5) there are ONLY these two users downloading! HTB should give

Hello, I''d like to try out HTB for traffic shaping. I have a test machine with Redhat 7.2 (kernel 2.4.10), I''ve downloaded kernel 2.4.17, applied the patch from http://luxik.cdi.cz/~devik/qos/htb/, recompiled the kernel (checked the option to use HTB in make menuconfig), and rebooted with the new kernel. When I try to add some rules with HTB (f.i. tc qdisc add dev eth0 root

hi all, i want to try htb3 with imq downloaded & patched imq & htb3 with kernel-2.4.18 on rh7.2 but got STUCK on step 1 :( this are what i did can anyone guide me what went wrong on the first step itself !!

Hello, I have been searching for HTB theory documentation and found two interesting sources - Devik''s page and docum.org FAQ. In some places they are contradictory which make me think that Devik''s theoretic document (marked "actual") is just too old and does not reflect the latest changes. After reading http://www.docum.org/docum.org/faq/cache/30.html and others, I

Hello, I''ve been using cbq''s "weight" parameter to influence distribution of excess bandwidth among sibling classes. Does htb offer something similar? So far I think that - you either use priorities - then excess bandwidth is offered to higher priority classes first, the rest (if any) is distributed among lower priority classes - or you don''t use

//Just to not forget eth0 is WAN and eth1 is LAN . The box is NATing my lan. I configured tcng to shape both download and upload and i got connection loss again. Maybe it is my script fault or it is something bad with packets marking . this is how i mark outgoing packets iptables -t mangle -A MYSHAPER-OUT -p tcp -s 192.168.1.23 -j MARK --set-mark $ip and this part of my script which is intented

Hi all, next version is here. It incorporated latest patch I sent to these lists and also disables other error message under some circumstances. Thanks to all who have sent the error reports. No critical bug fixed here but your error ogs will be shorter :). devik

Group, I am reading about tc (traffic control) and willing to get my feet wet. As requirement, there should be HTB compiled in the kernel. I grabbed a Mandrake 8.2 distro, and didn''t installed the kernel source. Anyone knows if the HTB is compiled in Mandrake 8.2, or point a way to find that out? I tried to read the /usr/src/kernel.xxxxx/.config file, but it doesn''t exists.
