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

Hi everyone, I''m new to tc but I need to use it to set up shaping on a new NAT box. In short: Each user must have their upload limited to 128kbit and downlink limited to 256kbit. Global bandwidth to be limited to 100Mbit Interactive packets to have higher priority 200+ users, so need to match packets fast So far I have managed to get the download limits working. However I need to

Hi all! I''m new to this list, and hope for some clarity in this matter: I have a home-gateway with linux-2.6.9 and iproute2 (ver:2.6.9). My following tc syntaxes. # eth0 internet scheduleing are: tc qdisc add dev eth0 root handle 1: htb default 20 tc class add dev eth0 parent 1: classid 1:1 htb rate 512kbit burst 6k tc class add dev eth0 parent 1:1 classid 1:10 htb rate 512kbit burst

hi to all, I''m studying traffic shaping using kernel 2.6.8 (debian sarge). well, I have this problem: priority doesn''t work. I try with: - qdisc prio: tc qdisc add dev eth1 root handle 12: prio bands 3 tc qdisc add dev eth1 parent 12:1 handle 13: tbf rate 10Mbit buffer 1600 limit 3000

Hi, I am trying to shape traffic to two VMs hosted in Xen. There seems to be very little information regarding this. I found this web page http://www.ioncannon.net/system-administration/57/limiting-bandwidth-usa ge-on-xen-linux-setup/ and followed the instructions. But, the real bandwidth experienced from clients always seems to exceed the set rate. Part of the problem may be because of the way

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

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

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

This is my first attempt at understanding lartc: I want to throttle outgoing bandwidth fo a certain tcp port and leave other traffic the way it was. so I put a prio qdisc at the root of eth0 (dummy priomap since i want to use filters to switch bands): $ tc qdisc add dev eth0 root handle 1: prio bands 2 priomap 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 then attach a tbf qdisc at 1:2 : $ tc qdisc add dev

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''m a tc newbie, and I think I am close to being able to use it to control one of the virtual web sites on our Gentoo Linux server. The site has it''s own IP address. I have a bit of a problem in that the way I originally configured tc, the busy site grabbed all the bandwidth, leaving none for the other (and more important) sites. Here is how I had configured it: tc

Hello *! My trafficshaping (tc-htb) drops packets very early, at least i suspect this. It drops about 30% fo the packets. The traffic-generating appication is running locally on the shaping host. I think i can lower this rate by increasing the packet-buffer, because the locally application will slow down with increasing buffer (tcp/ip). But i can´t find any options for that, i cycled the manual

Hello.. I have a linux box and I want to make priority on traffic generated by my LAN''s computers.. I don''t have a guaranted bandwidth, so I wanna use sfq... I want to make traffic to port 80 , 443 , 25 & 110 PRIORITY 1 Traffic src or dest 192.168.0.2 to make priority 2 And the rest to put it in proiority 3.. I did the following : tc qdisc add dev eth0 root handle 1:

Probably this is an old question, but i''m not able to find nothing about... So, i''ve just started to play with tc to limit the transfer speed to my hdsl connection. I''m using the tbf and the command # tc qdisc add dev eth0 root tbf rate 10kbit latency 50ms burst 1000 Then i''ve tried to transfer a big (20 Mbyte) file onto my lan, using ftp and the client

Hi All, I want to setup a machine to connect to internet at a limited rate of 64 kbps. That machine is connected to a switch. so my LAN and Internet both comes from the same eth0. How can I limit only the internet access from this machine to 64kbps and still using 100mbps for LAN I am trying to implement this Please guide me If i am wrong. I mark all the packets going out to LAN. Then I can

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

Hi, I have met the problem: when I use the shaping discipline tc qdisc add dev ppp0 parent 1:2 tbf latency 50ms burst 1450 rate 50kbit one of my application (namely, "aMule") starts leaving sockets in "CLOSING" state. These sockets accumulate and do not disappear. Eventually I have so many of these dead sockets that the kernel warns "Out of socket memory" in

The docs[1][2] suggest it''s 1024, but tc says something else: # tc qdisc add dev eth0 root tbf rate 1kbps latency 50ms burst 1500 # tc -s qdisc ls dev eth0 qdisc tbf 8009: rate 8000bit burst 1499b lat 48.8ms ^^^^^^^ Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) rate 0bit 0pps backlog 0b 0p requeues 0 If 1k were 1024, then I would have 8192bit above.
