I am using the script below to simulate a very high bandwidth connection.I find that I could not turn the bandwidth knob up to 100Mbit.I have had a look at this generally,but could not find an answer.any help would much appreciated as i have spent a lot of time on this and have not found any answers anywhere. In my test,I have four network cards and their rate are all 1000Mbps. my scripts: DEV="eth1" tc qdi...

Hi all, I''m having some problems setting up qdiscs on a bridge.The config looks a little like this: ifconfig ifb0 up # Bring up the IFB for this bridge. tc qdisc add dev eth2 ingress tc qdisc add dev eth3 ingress tc qdisc add dev ifb0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 cell 8 # Raw qdiscs on each bridge port tc qdisc add dev eth2 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 cell 8 tc qdisc add dev eth3 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 cell 8 tc filter add dev eth2 parent 1: protocol 0x8100 prio 5 u32 match u16 3000 0x0fff at 0 flow...

Hi to everybody. I read some info and documentation but i still can''t find how to make this simple setup for example . I just want to make priority of certain traffic without shaping the traffic . For example SSH and RDP first priority Mail second priority WEB and FTP third And everything else last priority. What will be the simple and best way to achieve this. I will appreciate

...#39;'m trying to get HTB working correctly on Centos4 (RHEL-based) with kernel 2.6.9-34.EL. I have two gigabit network interfaces bridged together and I have created the following: tc qdisc add dev eth2 root handle 1: htb default 1 r2q 8000 tc class add dev eth2 parent 1: classid 1:1 htb rate 100Mbit burst 24k cburst 24k (I have been trying different parameters). The network is passing ~80MBits of traffic but HTB is not seeing the rate correctly (which obviously causes problems when I try to shape a sub-set of the traffic). These are approx 1 second apart: [root@ ~]# tc -s -d class sh dev et...

Hi Guys, I have a couple of problems that are driving me nuts.

Hi, I''m trying to perform some (what I consider) basic traffic shaping on our network utilising HTB. I have mostly reused the example on the lartc.org site: tc qdisc add dev eth0 root handle 1: htb default 10 tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbit burst 24k tc class add dev eth0 parent 1:1 classid 1:10 htb rate 50mbit ceil 80mbit burst 19k tc class add dev eth0 parent 1:1 classid 1:20 htb rate 1mbit ceil 1mbit tc qdisc add dev eth0 parent 1:10 handle 10: sfq perturb 10 tc qdisc add dev eth0 parent 1:20 handle 20: sfq perturb 10 tc filter add...

...are downloading files at the same time, they need to never be more than 384Kbit together.

Hello lartc, Testing some rules I found out that any rules are slowing down large pings!

Hi, I have a basic router that is shaping traffic, and it seems to be working at the moment. We have a 100Mbit connection to the internet, however we get charged for each mbit that we use and so have to shape/limit the traffic to avoid huge bills and my boss getting cross!! We have a /29 subnets set up as follows: tc qdisc add dev eth0 root tbf rate 0.8Mbit latency 50ms burst 10k tc qdisc add dev eth1 ro...

Hi everybody, i am new to this list so dont blame me if i will talk about nothing.. At this moment i am experimenting with htb + tc u32 filters , the problem is that i want some traffic to be unshaped so i did this.. tc qdisc add dev eth0 root handle 10: htb default 20 tc class add dev eth0 parent 10: classid 10:2 htb rate 256Kbit THIS IS TRAFFIC I WANT NOT TO BE SHAPED tc filter add dev eth0

Hi folks. For quite a while, I tried to use linux (cbq and htb) to control bandwidth in order to replace a cisco equipment used to play this role on our network. After trying here and there, with a bunch of different distros, different versions, different compilations, ... the closest I could get was as follows: (using htb.init and cbq.init) Desired BW ==> Achieved BW 128k ==> 404.78

...s. I read that I should test with r2q values to gain accuracy and stop the warnings but I made some tests with r2q and with burst and I still get the warnings. Any ideas on this issue will be very helpful. The script seems to be working as the bandwidth for the IPs is being shaped. The NIC works at 100mbit and the Internet link that is shared is 128kbit. iptable rules mark the packets on the PREROUTING and POSTROUTING chain Here is what I tested and then the rules I´m using: With this tests: 1.
