similar to: How many (htb) tc classes and qdiscs are too many?

Hi, I am trying to use htb to limit bandwidth on loopback for traffic through particular port. Here is the script I am using. tc qdisc add dev lo root handle 1: htb tc class add dev lo parent 1: classid 1:1 htb rate 100kbit ceil 100kbit tc class add dev lo parent 1:1 classid 1:10 htb rate 50kbit ceil 50kbit tc class add dev lo parent 1:1 classid 1:11 htb rate 50kbit ceil 50kbit tc filter add

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

I''m using HFSC to limit bandwidth for our wireless customers. However, I''d also like the bandwidth prioritized based on packet type. This is what I''m trying right now, and I''d just like some input from anyone out there knowledgeable in this on whether it does what I want it to do: Eth1 -> HFSC ........|-> HFSC (User1) (Min 512 Kb, Max 1024 Kb, Burst 1536

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 I have a trouble configuring the qdiscs, when I indicate the "perturb 10" option to tc, i gives me this error: tc qdisc add dev eth0 parent 5:1323 handle 1323 sfq perturb 10 RTNETLINK answers: Invalid argument if I don''t put the "perturb 10" option, it works. another question is about iptables, when I indicate the " --set-mark" option: iptables -t

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 ! I have a single host which is connected via an 512kbit ADSL link to the n= et. I quite often use some realaudio application that uses some bandwidth = and I want to avoid other traffic to scale that bandwidth down. So I used = some classes (with htb) on imq0 device and applied some filters and it see= ms to work in most cases. However, there are some sites with which downloa= d is

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, 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

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

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

I have: tc qdisc add dev imq0 root handle 1: htb default 30 tc class add dev imq0 parent 1: classid 1:1 htb rate 512kbit ceil 512kbit tc class add dev imq0 parent 1:1 classid 1:30 htb rate 64kbit ceil 512kbit then: iptables -t mangle -A PREROUTING -i ppp0 -s 192.168.2.2 -j IMQ --todev 0 tc class add dev imq0 parent 1:1 classid 1:22 htb rate 64kbit ceil 128kbit tc filter add dev imq0 protocol

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

Hello, I wrote a simple traffic shaping script (below) that should have allowed me to shape my internet traffic a bit (ppp0 - adsl 128kbit/64kbit; local interface eth0). The script works only partially - the speed is being limited but too much. Without running this script my download rate is about 10kBytes (with second computer also downloading at about 6kBytes). After running it my download speed

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

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!

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
