Hello, I am trying to get the TC command to work on our debian box to limit traffic in and out to 12 Meg. The command I am using is: tc qdisc add dev eth0 root tbf rate 12000kbit latency 25ms burst 1600 tc qdisc add dev eth1 root tbf rate 12000kbit latency 25ms burst 1600 The problem I am having is that the bandwidth exceeds the 12 Meg by almost 5 Meg. Any help is appreciated.

Hi, Having issues getting a replace command working correctly. The error reported is "RTNETLINK answers: Invalid argument" which isn''t descriptive or helpful. The command i''m running is: tc qdisc replace dev ppp0 parent 8001:D handle D: tbf rate 5Kbit burst 5kb latency 70ms The idea being to replace an sfq with handle D and hopefully limit a certain user in my

Hey, I have a problem adding a filter matching anything, here is my setup: ############### tc qdisc add dev eth0 handle 1: root prio tc qdisc add dev eth0 parent 1:1 handle 10: pfifo tc qdisc add dev eth0 parent 1:2 handle 20: tbf latency 50ms rate \ 128kbit burst 256kbit tc filter add dev eth0 protocol ip parent 1:0 prio 1 handle 666 fw \ flowid 1:2 tc filter add dev eth0 protocol ip parent

Hi, i''m sort of testing a configuration and things are not working sa i planned. i have the following network diagram: PC1 to 7 cnneced on the same ethernet hub. PC1 PC2 PC 3 PC4 PC5 PC6 on network 192.168.5.0 PC6 and PC7 on network 192.168.1.0 so PC6 work as a router. in addition, PC6 is connected to both network on the same device eth0. now on PC6, put a tbf on dev eth0 root

Hi i have found a problem related with tbf and the latency that the tbf calculates.. I have used the following parameters for burst and limit burst 100Kbit limit 500Kbit lat81.8ms burst 6Kbit limit 6Kbit lat 0us burst 200Kbit limit 100Kbit lat 4294.9s As u can see in the 3rd column the latency for 100Kbit burst and 500Kbit limit is 81.8ms but for 200Kbit and limit 100Kbit is 4294.9s!!! How

Hello mailing list, i stand bevor a mystery and cannot explain it J. I want to do shaping and prioritization and I have done these following configurations and simulations. I can´t explain, that the combination of PRIO and TBF is much better than the HTB (with the prio parameter) alone or in combination with the SFQ. Here are my example configurations: 2 Traffic Classes http (80 = 0x50) and

I''m trying to fill a token bucket with enough tokens to burst several gigs of data. However, it doesn''t seem to get any higher than ~3.9GB: >tc qdisc add dev eth0 root tbf rate 1440kbit latency 50ms \ burst 16000000000 >tc qdisc show dev eth0 qdisc tbf 800b: rate 1440Kbit burst 3908420240b lat 2197.8s A smaller attempt of ~1.6 gigs works just fine: >tc qdisc

Hi! I was updated kernel from 2.4.22 to 2.4.23 and now tc tools can''t correctly determine default (pfifo_fast) qdisc on interface: # tc/tc qdisc ls dev ppp0 qdisc pfifo_fast 0: [Unknown qdisc, optlen=20] but, if I assign f.e. cbq qdisc for some device all show correctly: # tc/tc qdisc ls dev ppp1 qdisc tbf 8009: rate 32Kbit burst 10Kb lat 1.5s qdisc cbq 66: rate 10Mbit

Hi I''m completely stuck with the tcng language - I assume there must be some way to arrange queues hierachically like eth1 | TBF | PRIO / \ class class but my attempt (below) produces a "inferno.tc:8: qdisc "tbf" has no classes near "prio"" when run through tcc. dev eth1 { egress { tbf (rate 128kbps, burst 64kb,

Good afternoon, I am a newbie to lartc. I have read the HOWTO. I set up a CBQ traffic control using the following commands, and it caused my VNC connection to break frequently. ======================================================================= **CBQ: cbq-1280.My_shaper /sbin/tc qdisc del dev lo root /sbin/tc qdisc add dev lo root handle 1 cbq bandwidth 20Mbps avpkt 1000 cell 8 /sbin/tc

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

Hi have set the following tbf tc qdisc add dev eth0 root tbf rate 0.5mbit \ burst 5kb latency 70ms peakrate 1mbit \ minburst 1540 I want to add a filter so the ip traffic pass from it.. plz help me __________________________________ Yahoo!

Hi, I would like to know how to specify the token rate when a tbf qdic is created using tc tool.. Will it be a default value when tbf qdisc is created? This could be a silly question.... im quite new to all these stuff.. but im really interested.. any help will be most appreciated... thanks in advance, sanjeev -- ______________________________________________ Check out the latest SMS

Hello, I was attempting to throttle egress traffic to a specific rate using a tbf. As a starting point I used an example from the LARTC howto, which goes: tc qdisc add dev eth1 root tbf rate 220kbit latency 50ms burst 1540 I then attempt a large fetch from another machine via wget (~40 megs) and the rate was clamped down to about 12Kbytes/s. As this seemed too much, I gradually increased

I presently use TBF with this syntax: tc qdisc add dev eth0 parent 1:100 tbf buffer=15000/8 LIMIT=30000 MTU=1500 parent class is a cbq with rate=128Kbit when I want to add PEAK, I get always RTNETLINK error: Invalid argument. Maybe be I don''t understand this parameter. What I know about it, it''s that it can control short-term burst traffic, and it''s what I need to do.

Hi Everyone, This is a simple question but I don''t understand why the below tbf is not working as expected by throttling traffic to 5kbps If I throttle a PC''s traffic using the below when traffic exceeds 5kbps packets start getting dropped (as they should) but all traffic gets dropped. not just the bit over 5kbps. TC="tc add dev ppp0" $TC parent 8001:2 handle 2:

I am using tbf to do rate limitation. i set the rate, burst and latency parameters for tbf. but when i start passing data i notice that there is an initial burst and then the rate goes down to the configured level. is this because tbf starts with a full bucket? thanks. __________________________________________________ Do You Yahoo!?

Dear friends, thanks for the last advices about TBF. After reading the tbf.pdf document I got a better insight of the problems I had trying to limit the bandwith on my testbed with a high resolution. The question I have now is: Would I get an immediatly better resolution result if I change the #define HZ to 1000 for my Linux box? I have a Pentium Celeron 700 MHz, and I would like to see the tbf

Hi, I am new to kernel programming. My task is to route packets from different hosts through one single token bucket filter as we are trying to model a wireless scenario with many hosts communicating and sharing the same bandwidth.So the idea we came up with was to route packets from different hosts to user space using Netfilter and then send them through a common tbf implemented in user space in

Kernel people tell me users should never need to know the value of HZ used by the currently running kernel. One kernel hacker even told me that Linus once changed the value from 100 to 1000 just to see user space programs break. However, it is needed for the buffer parameter in TBF. The tc-tbf(8) manpage: If your buffer is too small, packets may be dropped because more tokens arrive per timer
