An earlier exchange about someone seeing the rate larger than the ceiling is posted below. Andy explained the reason for the "above ceiling" rate in Daniel''s output . . . but I just saw an example that doesn''t fit. >> tc output >> class htb 1:14 parent 1:1 leaf 14: prio 1 quantum 3072 rate 256000bit ceil 282000bit burst 1820b/8 mpu 0b overhead 0b

Hello! I am using shapping whith htb. My question is what are the propper values I can use in rate/ceil. I use htb.init for quick building of my classes/rules and have 2 groups of clients with 2 different bandwidth assignemet : A. 16--->48kbps B. 16---->128Kbps It seems to work everything OK, but can I use lower values for rate like 8Kbps ? What about using 32-->96Kbps? I let htb to

Hi, I have implemented qos at my gateway, mostly for speeding up dns and [video,voice] chat traffic and to slow down p2p traffic. It seems every thing is working properly, as by browsing speed has been improved. But I want to test it by sending various traffic and to see through which qdisc the traffic flows, so that i can be certain that it is working the way I want it to work. The rules

I''m attempting to set up a hierarchy of tc qdiscs with filters, but the filters don''t seem to be working correctly.  I''m running iptables 1.3.5 with iproute 2.6.16.20060323 on a Gentoo 2.6.18 kernel.  The system takes all my tc setup, but does not filter packets as I am expecting it to based on my ruleset. My tc qdiscs and classes are added correctly and report as

Hi, What is the difference between the rate values you specify in "tc class ... htb ... rate ..." and in "tc filter ... police ... rate ..."? Thanks in advance.

-------------- eth0------eth1 eth0------------ |211.241.219.xx | --- | ROUTER | --- |192.168.1.4 | --------------- --------- ------------ when i send traffic from ROUTER to 211.241.219.xx or 192.168.1.4(masquraded), the filter works fine... In ROUTER, tc filter policy is like this: tc filter add dev eth0 parent 1:0 protocol ip u32 match ip dport 80 0xffff

I am using HTB+IMQ on an Ethernet bridge and tc for statistics reporting. I am finding that tc reported rate is about 5-10% less than that reported by IPTraf for the same traffic. Has anyone observed this before? Which is more accurate? Rajesh

I would like to test police in ingress. I use kernel 2.4.20. I use this configuration: iptables -t mangle -A PREROUTING -i eth0 -s 10.31.12.2 -d 10.31.11.2 -p udp --dport 1001 -j MARK --set-mark 1 iptables -t mangle -A PREROUTING -i eth0 -s 10.31.12.2 -d 10.31.11.2 -p udp --dport 1002 -j MARK --set-mark 2 iptables -t mangle -A PREROUTING -i eth0 -s 10.31.12.2 -d 10.31.11.2 -p udp --dport 1003 -j

Hello, I use rrdtool to graph the traffic in the different classes on an interface, eth1. Basically, I use the output from tc -s qdisc ls dev eth1 my tc script (which is only for testing the graphing) looks like this: /sbin/tc qdisc add dev eth1 root handle 1: htb default 20 r2q 1 /sbin/tc class add dev eth1 parent 1: classid 1:1 htb rate 200kbit burst 15k /sbin/tc class add dev eth1 parent

Hi, I''ve have my IP and TC scripts working OK but my rate limiting does not seem to be being appiled. My available download speed is around 150kbps. I''d like to limit this box and the machines it forwards for to 10kbps each, a total of 20kbps. Thus leaving 130kbps unused. The classes I''ve created are simple and the stats show they are moving bytes OK, however; the

Hi Gang, I''m still experiencing some bandwidth starvation with my script (below), so I decided to look at the statistics by using: tc -s qdisc show dev eth0 (where eth0 is the interface I''m trying to rate-limit outbound packets) I get, for example: qdisc sfq 21: quantum 1514b perturb 10sec Sent 133527926 bytes 413260 pkts (dropped 0, overlimits 0) qdisc sfq 20: quantum

Hi, I have a question about policy filters. All I want is incoming traffic being restricted to a specific rate. At the moment, I get way lower rates than specified. So far, I did use a filter much like Wondershaper does: 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

I am currently using the ultimate-tc script from http://lartc.org/howto/lartc.cookbook.ultimate-tc.html and I want to make sure that internet radio packets (mp3 streaming audio) will always get through no matter what. I have added some iptables commands like this: iptables -A OUTPUT -t mangle -p tcp --dport 8000 -j TOS --set-tos Minimize-Delay iptables -A OUTPUT -t mangle -p tcp --sport 8000 -j

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

Hi folks. I started to play with tc+htb last week, and I must confess that this thing is really driving me nuts. All we want to do is control bw, with no borrowing. In order to get the feeling on this subject, I have setup the following test bed. ---A---B---C--- On B: eth0 connecting A and eth1 connecting C. The script. tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb

Hi al.. I just write program that helps to configure tc with HTB and iptables CLASS extension. Its written in perl and uses Apache like config files. Program can be found on http://sourceforge.net/projects/ist-shaper/ or http://www.ingwar.eu.org/ist-shaper/ In few days will be new version with time aware rules. The simply config file looks like this.
