similar to: HTB ATM MPU OVERHEAD (without any patching)

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.

//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

It seems Andreas Klauer''s fairnat has experimental support for using HTB''s MPU and overhead options. fairnat.config: # Use MPU for HTB. From the LARTC Howto on MPU: # "A zero-sized packet does not use zero bandwidth. For ethernet, no packet # uses less than 64 bytes. The Minimum Packet Unit determines the minimal # token usage for a packet." HTB_MPU=0 # HTB_MPU=64

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 :

Hi all. I''m going on my 3rd week trying to get a simple traffic shapping to work the right way :( !! My goal it to shape the traffic coming from one machine (pc1) to another machine (pc2) throught the "eth0" interface. My test configuration is as follows: PC1   IP: 192.168.105.237   Mask: 255.255.255.0   OS: Red Hat Linux Kernel 2.4.20-8   Rules:

I have been trying to optimise my ADSL connections for VOIP. Funny things were happening - for example increasing the ping packet size by 50% had no effect, but then adding one byte had a major effect. It took me a while to figure out that I was seeing the effects of the fixed ATM cell size. This is probably obvious to some of you. For the rest: ADSL uses ATM as its transport. An ATM

Hello, I''m using tc to limit the bandwidth of our wireless customers. I have a working script, but I''m not happy with it. I''m trying to write a more sophisticated script, but when I run it, it give me this error: RTNETLINK answers: File exists I have no idea what this error means or how to fix it. Here is a portion of the script (the whole script shapes several

Hello, I have a serious problem with HTB which I wasn''t able to solve myself. I run a masquerading router with ppp0 as interface to the Internet. Three clients need to share a downstream of 1 MBit, which I want to divide with tc. When I see a packet being forwarded to one of these clients, I give it the appropriate unique mark: iptables -t mangle -A FORWARD -d 192.168.34.141 -j MARK

Hi, I am trying to setup a shaper for my linux box and I am experiencing some problems. What I am trying to do is priorizing packets on the egress link, therefore I have setup some prio classes etc. The priorizing seem to work but the problem is that the ceil parameter doesnt seem to work on non leafs. This is what stats show: > class htb 1:1 root rate 3000bit ceil 3000bit burst 1602b/8 mpu

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?
