Hi! By iptables I set marking (-j MARK) just before -j IMQ. There are only three marks. Exectly all of them are ditected to 1:20 Why I see 3 pkts in default 1:30? How explain it? ### imq0: queueing disciplines qdisc htb 1: r2q 10 default 30 direct_packets_stat 0 Sent 631429 bytes 1812 pkts (dropped 0, overlimits 20) ### imq0: traffic classes class htb 1:20 root prio 0 rate 100Kbit ceil

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

Andreas, Since I understand your ASCII art and comments, I would very much appreciate it if you would draw what you see and criticize the following. Hopefully I''ll better understand after that!

Hello everyone: As it is known, when you limit uplink bandwidth it usually gets downlink bandwidth to a lower value. I just want to know what is the optimal configuration for eth1 and imq0 according to some variables of tc(HTB), txqueuelen, mtu, etc. to make these packet flows less independent on an ethernet based network. Thank you in advance. -Diego

What is the difference between lines below? $TC filter add dev imq0 parent 1:0 prio 5 handle 1: protocol ip u32 divisor 1 $TC filter add dev imq0 parent 1:0 prio 5 handle 2: protocol ip u32 divisor 256 What divisor is doing?

We have a Linux box that is acting as the gateway to the internet for about 400 people, typically there are not more then 50 of them using the internet at any given time. We would like to provide different levels of access to different users. For example 128kbps to some users and 256kbps to others. We have considered creating a class and qdisc for each user (using htb) however we don''t

HTB and imq was used to control traffic. modprobe imq numdevs=3 but only imq0 and imq1 can be used; if there are five NICs, please tell me how can I can use imq2 , imq3 and so on. _________________________________________________________ Do You Yahoo!? 新鲜到底,娱乐到家 - 雅虎推出免费娱乐电子周报! http://cn.ent.yahoo.com/newsletter/index.html _______________________________________________ LARTC mailing list /

Hello I have 2 class-B networks (172.22.0.0/16 and 172.23.0.0/16, over 130k of ip''s) and need to setup traffic tbf shapers with 64kb/s for each ip from 172.22.0.0/16 and 128kb/s for each ip from 172.23.0.0/16 just read lartc and don''t understand how to use u32 for decreasing number of rules and hashing

Hi all, my IMQ device works OK (thanks to Andy Furniss), but now I''ve problems to attach the traffic in the qdisc''s. This is my conf: ----------------------------------------------------------------------- INET | |eth0 300Kbps ROUTER (NAT) |eth1 | LAN ----------------------------------------------------------------------- MAX=300 tc qdisc add dev imq0 root handle 1: htb

Hi folks, I`ve a problem to use HTB and SFQ. The first script, below, to show a simple configuration, does work fine...!!! But, in the second example, does not work, becouse i put more code to clasify the traffic by protocol, http and ftp in this case. Somebody can tell me the errors? Thx, in advance.- NOTICE: IMQ device is to asociate with ETH1 my external iface. SCRIPT que funciona:

Hi All, I''m trying to create a contended section of bandwidth using IMQ. I have the imq0 device up and running, with traffic passing through it. Firstly, I need to throttle the entire device imq0 to 2mbit/s. I would then like to add throttle rules for individual IP addresses, allowing them to pass up to 512kbit/s each, as long as imq0 has not reached its 2mbit/s. The configuration

Hello, I''ve just recently started to use IMQ and I got puzzled after seeing the imq usage example on the linuximq.net site: It was something like this: tc qdisc add dev imq0 handle 1: root htb default 1 tc class add dev imq0 parent 1: classid 1:1 htb rate 1mbit tc qdisc add dev imq0 parent 1:1 handle 10: htb default 5 tc class add dev imq0 parent 10: classid 10:1 htb rate 256kbit

Hello to all people there . Can i guarantee ICMP respond time no metter how loaded is internet line . i have typical NATed enviroiment like External IP |linux router| LAN - 192.168.0.0/24 i have example setup with IMQ but is it possible to be done also if i attache htb to eth0 and eth1 for example . if i start shaper ping i better that without shaper but it''s not guarantted i mean

i''m trying to limit upload and download but something is wrong(it is about NAT) i will post here my "script" maybe someone could tell me what is wrong my kernel(2.6.9) is patch with imq(linuximq.net) and my iptables(1.2.11) also #flush tc qdisc del dev eth0 root tc qdisc del dev eth1 root tc qdisc del dev imq0 root tc qdisc del dev imq1 root ifconfig imq0 down

Hi all and tc Gururs i have patched the IMQ and htb to kernel, but when i do egress filtering, iam not able to see any traffic and excusted the following the commands modprobe imq numdevs=1 tc qdisc add dev imq0 handle 1: root htb default 1 tc class add dev imq0 parent 1: classid 1:1 htb rate 100kbit tc qdisc add dev imq0 parent 1:1 handle 10: htb default 1 tc class add dev imq0 parent

Hi, I can''t get traffic shaping working. This is my situation: -------- ------ Net1 ----- |router| -------------------- | TC | ----------- Net2 -------- leased line ------ eth1 eth0 We use the leased line for normal traffic but also for synchronisation between 2 servers. The leased line is 2mbit. The synchronisation
