Hi All, I''m trying to create a contended section of bandwidth using IMQ. I have the imq0 device up and running, with traffic passing through it. Firstly, I need to throttle the entire device imq0 to 2mbit/s. I would then like to add throttle rules for individual IP addresses, allowing them to pass up to 512kbit/s each, as long as imq0 has not reached its 2mbit/s. The configuration...

...#39;'m open to suggestions. I do have a tcng configuration question though. I''m trying to replicate my earlier simple configuration with TC. I''m sure what I have is far from optimal - but I wanted to stick as close to my original tc architecture as I could so: dev "imq0" { egress { class (<$four_vip>) if ip_src == 192.168.4.2/32; class (<$six_vip>) i...

Hello, I have HTB on IMQ device. My rate does not work as I configured. I configured 1920kbit/s and I can download only about 290kbit/s (while it should be the whole bandwidth).

Hello, I''ve just recently started to use IMQ and I got puzzled after seeing the imq usage example on the linuximq.net site: It was something like this: tc qdisc add dev imq0 handle 1: root htb default 1 tc class add dev imq0 parent 1: classid 1:1 htb rate 1mbit tc qdisc add dev imq0 parent 1:1 handle 10: htb default 5 tc class add dev imq0 parent 10: classid 10:1 htb rate 256kbit burst 30k prio 1 and I tried the following (like in the classic htb examples from lartc)...

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 interrupted if bandwidth is limited. I tried to trace it down and did= some simple test: modprobe imq numdevs=3D1 tc qdisc add dev imq0 root handle 1: htb default 10 tc cla...

.... Normally you would shape the outgoing traffic on eth0, but this doesn''t work. We even tried to limit eth0 to 20kbit, but the synch-traffic completely fills the leased line and no other traffic gets through. We found a temporary fix by using IMQ with iptables: /sbin/tc qdisc del root dev imq0 /sbin/tc qdisc add dev imq0 root handle 1: htb default 20 /sbin/tc class add dev imq0 parent 1: classid 1:1 htb rate 2Mbit burst 6k /sbin/tc class add dev imq0 parent 1:1 classid 1:10 htb rate 64kbit ceil 787kbit /sbin/tc class add dev imq0 parent 1:1 classid 1:20 htb rate 2Mbit /sbin/tc qdisc add...
