similar to: Ingress Shaping using IMQ

Todays quick question: Ive had problems with imq and getting my setup to work as planned. Im thinking that a better solution for shaping incoming traffic would be to put a little limit in the outer interface of the router box with ingress, and the shape traffic on the inner interface with htb. Would that be better than using imq? -- Patrick Petersen <lartc@schmakk.dk>

I tried installing the WonderShaper on my internal link, mostly to get the SFQ installed. I set uplink and downlink to 100000 to match the link speed and changed the bandwidth on the cbq line to 100mbit. This killed transfer speed *to* the box, knocking it from 30-40 Mbps down to about 800 kbps. Commenting out just the ingress control restored the speed. What about the ingress policer would do

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

Hi, I am trying to do both ingress and egress bandwidth management on a bridge. eth0 is the WAN interface. IPTraf shows that the following script is running successfully and it limits bandwidth both ways to 256 KB However when I want to see the statistics using tc - it only shows me stats for htb class and not for ingress class. The tc output is as follows: tc -s -d class show dev eth0 class

ingress can be used to control the incoming packet, such as: tc qdisc add dev eth0 handle ffff: ingress tc filter add dev eth0 parent ffff: protocol ip prio 5 u32 match ip src 172.16.1.11 police rate 10kbit burst 10k drop flowid :1 tc filter add dev eth0 parent ffff: protocol ip prio 5 u32 match ip src 172.16.1.22 police rate 10kbit burst 10k drop flowid :2 first ,I do not sure these method can

Hi all, It is my understanding that with HTB, the rate and the ceiling are divided over the elements of the class. E.g. using a rate of 100 kb and a ceiling of 2000 kb for a class with 10 elements on a 100Mb NIC, the effect of the ceiling will be that if all elements are generating their maximimum possible trafic they will be effectively limited to ~ ceiling / number of elements, in this case

Hello all! I''ve just subscribed to the list after looking around on Google and checking out the TC source code a bit. Here''s my situation: I have a megabit DSL line that I''d like to set up some shaping on. I only have access to the linux router on my (client) end. Because of that, I was looking to do some shaping using the ''ingress'' qdisc. However,

Hi, I have typical situation, local LAN with private addresses, translated via NAT to internet. I need to shape ingress traffic (from internet to local LAN) in several HTB queues accorting to destination (private not public) IP. So I need mark packets to divide them to corresponding queue. According to http://www.docum.org/stef.coene/qos/kptd/ I thing I have only one way how to do it, because

Objective: All web traffic originating from my proxy server should be forwarded through interface eth2 instead of the default eth0. The reply should take the same path back to the proxy server. Problem: On the return bout, the kernel doesn''t pass the packet to the higher layers. The reply seems to be getting tossed away between PREROUTING and INPUT Netfilter chains.

tc class add dev $DEV parent 1: classid 1:1 htb rate ${UPLINK}kbit burst 6k tc qdisc add dev $DEV handle ffff: ingress tc filter add dev $DEV parent ffff: protocol ip prio 50 u32 match ip src \ 0.0.0.0/0 police rate ${DOWNLINK}kbit burst 10k drop flowid :1 why does the download is being sent to class 1 which is limited by uplink ? why the rate is being mentioned in filter and in class ?

Hello, After reading the excellent HOWTO I got traffic shaping working nicely over ethernet devices on a test setup. I can''t put this setup live though, because our main firewall has three 2mbit hdlc interfaces instead of a single device. We are using multipath routing using iproute2 nexthop at the moment, and that works fine for firewalling. But now I have a need for shaping and

Hi, I have more ethernet cards. Egress shaping with HTB over eth0 works fine, ingress shaping with HTB over IMQ works also fine, but in both of cases I use only one class of traffic. Now I want to divide traffic to 3 classes on other interface (egress to ineternal network). I try this command sequense tc qdisc add dev eth1 root handle 1: htb default 12 tc class add dev eth1 parent 1: classid

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 am learning tcng without having experiance of tc and I am trying to build something that shall schedule traffic dependent on the value in the IPv4 packets ip_ttl field. I have read the tcng reference manual and cannot find information about forwarding. Is it possible to farward packets from ingress to egress without sending them upwards in layers?

Hello , I am trying to install an ingress qdisc on a slackware 7 , 2.2.20 box . I have installed iproute2-2.4.7-now-ss010824.tar.gz . I `ve built all the QOS stuff in my kernel . Playing with cbq sfq etc works ok . However when i try to setup ingress i get the infamous RNETLINK message tc qdisc add dev eth0 handle ffff: ingress RTNETLINK answers: No such file or directory Something weird ,

hi stef oone more pb while shaping incoming traffic with imq .this one tc qdisc add dev imq0 root handle 1: htb default 20 tc class add dev imq0 parent 1: classid 1:1 htb rate 2mbit burst 15k tc class add dev imq0 parent 1:1 classid 1:10 htb rate 1mbit tc class add dev imq0 parent 1:1 classid 1:20 htb rate 1mbit tc qdisc add dev imq0 parent 1:10 handle 10: pfifo tc qdisc add dev imq0 parent

Hello all, My company is sharing it''s internet access with a neighbor and the neighbor in question was eating our bandwidth (both in upload and download) most of the time. I finally set up a linux router to limit the incoming/outgoing bandwidth to his network by adding a tbf on eth0 interface and eth1 interface of the router (neighbor is behind eth1 and we are in-between him and the

I am successfully running ingress (IMQ) and egress (HTB) shaping on a bridge. Is there any way to combine and share the bandwidth between ingress and egress? Example: I have set up www service for egress at 128 KB and ingress at 256 KB. The shaping on them works fine separately. However, I want to create a single virtual pipe for www traffic and limit both ingress and egress combined to 256 KB.

Hi stef; imq patch of 2.2.17 form http://luxik.cdi.cz/~devik/qos/imq.htm diff against 2.2.17 Can you tell me how imq work with ipchains? thanks for your help regards, haipe _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Hello All Its first time i posting to this mail list :). I have done something (maybe) important. I write new IMQ device driver based from Martin Devera and Patrick McHardy implementation with device EOS support. My current implementation supporting only egress trafic shaping and kernel 2.4.25.
