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 I currently have is as follows: tc qdisc add dev imq0 root handle 1: htb default 1 tc class add dev imq0 parent 1:...

...tion: -------- ------ 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 generates too much traffic and uses completely the 2mbit capacity of the leased line. This is no problem during night, but we want to limit the synchronisation traffic during day (or in other words: the sync-traffic should get the lowest priority and the other traffic can use u...

Hi there, I have two ethernet connections of 2Mbit/s each and I''m trying to add them together to one 4Mbit/s connection but I cannot get more than approximate 1Mbit/s! My setup: I have a LAN (10.2.18.0/24), connected to a larger network (10.0.0.0/8) by two WAN-connections with 2Mbit/s each. On each end I have a Linux router. I first setup...

Hello list, Please don''t shoot me. I know I''m doing something with bonding that bonding wasn''t made for. I just want to give it a try. I want a simple mechanism to have a failover on a 24Mbit line to a 2Mbit line in case the 24Mbit line goes down. Between A and B there are two lines: a 24Mbit and a 2Mbit. I use two OpenVPN tunnels with tap devices: +-- tap0 (A)--- OpenVPN tunnel over 24Mbit --- tap0 (B) ---+ | | A-+...

Hi! I have a setup where I want to prefer traffic on one port (for testing purposes I used port 22) my setup is : tc qdisc add dev eth3 root handle 1: htb default 30 tc class add dev eth3 parent 1: classid 1:1 htb rate 96mbit burst 15k tc class add dev eth3 parent 1: classid 1:7 htb rate 2mbit burst 15k tc class add dev eth3 parent 1:1 classid 1:10 htb rate 96mbit burst 15k tc class add dev eth3 parent 1:7 classid 1:20 htb rate 1800kbit ceil 2mbit burst 15k tc class add dev eth3 parent 1:7 classid 1:30 htb rate 200kbit ceil 2mbit burst 15k tc qdisc add dev eth3 parent 1:10 handle 10: s...

Yes, last night it was 4Mbps the rate of incoming mails. I was wondering if I apply HTB to the following scheme: router -> gw-iface -> MX-server If HTB (new verb) the interface that communicates with MX, say, 2mbit, what will occur to the Input queue of gw-router-iface? Will I still get the link full for 4mbit or will it get lower to 2mbit too, as the inner interface? Appreciate comments -- Je

Hello... I have one 2Mbit WAN interfaces and two vlan LAN interfaces - vlan2 and vlan3. I''d like to limit bandwidth something like this: rate 1Mbit ceil 2Mbit for vlan2 and rate 1Mbit ceil 2Mbit for vlan3 with possibility to borrow bandwidth between vlan2 and vlan3. ^^^^^^^^^^^^^^^^^^^ Is it p...

Dear list, I have the problem that child classes don''t seem to issue the parent class to borrow from their parent. This is a simplified version of my script: tc qdisc del dev $DEV root tc qdisc add dev $DEV root handle 1: htb default 10 tc class add dev $DEV parent 1: classid 1:1 htb rate 10mbit tc class add dev $DEV parent 1:1 classid 1:10 htb rate 1kbit ceil 512kbit #groups tc

...ollowing problem on my hand..... I''m a sysop for a school in the netherlands. We have a network with 5 different schools (and 1 administration). Each of those have their own ip range in the private network (10.4.0.0 10.5.0.0 and so on). For all these schools we have an internet uplink of 2mbit. And this bandwidth should be shared as fairly as possible. So I started reading the the lartc HOWTO but was startled by the technical terms I found there...... I kinda understand what i meant..... but would like some advice which option I should further investigate. What I want to do is spit...

Hi list... I work for a school in the netherlands with a 2mbit Internet uplink and about 3800 eager student who want to play games on the Internet using one of our 800 workstations. Problem was that those game playing students are concentrated in 2 of our 6 physical locations... and they consumed the bandwidth which the other location would like to use for ed...

Hello all! As far as I know that the traffic that will pass thru the router is balanced so that all connections have the same privilegies. Is it possible to configure the linux based router so that all computers will have the same privilegies? I mean that if in default case full traffic is splitted by connections, so I need to split it by users to prevent one user occupy all traffic by starting

Hi all, I have an average 2mbit multicast stream that once in a while bursts high (up to 20mbit/s) in short periods (about 200ms). Could anyone please help me with directions using tc for configuing leaky bucket shaping to this stream? I have a 5mbit/s ceiling. My system is running gentoo linux 2.6.14, and I have compiled in all...

Hi, I'm using Theora for live video chat. My problem is, at higher bitrates the bandwidth peaks caused by key frames are so high that most key frames get dropped in UDP traffic. The peaks are so strong that I still get many packet loss artifacts when sending with 1Mbit/s bitrate on a 2Mbit/s connection. I measured delta frames to be around 12kbyte and key frames up to 100kbyte in 1280x720 video at 15fps even with lowest rate buffer settings. I can send 2Mbit/s without errors when using heavy traffic shaping, but this causes clearly visible delay. In pre-1.0 API there was a paramet...

Hi I have Linux box (Debian) that acting as a bridge. Eth0 and Eth1 are bridged (br0). Br0 have public IP. Eth0 connects to the internet. Eth1 connect to servers in DMZ (with public IPs). Eth2 connects my Lan (192.168.1.0/24). My connections is 2Mbit/2Mbit. I''m doing SNAT for my Lan. QoS on eth0 works fine for DMZ, but is there a possibility to doing QoS on eth0 based on private IPs ( 192.168.1.0/24 ) ? -- Pozdrawiam Marcin, slacklist@op.pl

Hello I have two linux machines connected via 2 dsl lines (bonded) 192.168.0.1-eth0-dsl---2Mbit---dsl-eth0-192.168.0.2 ^-eth1-dsl---2Mbit---dsl-eth1-^ so the final figure is something like this: 192.168.0.1-bond0---4Mbit---bond0-192.168.0.2 I can only use arp monitoring for fail checking - if one dsl line fails - automatically use only the other one. I set up everything correctly...

R2 - R3 is a 2mbit link R1 - R2 is a 10mbit link R2 have multiple interfaces and other 10mbit links I have a 32kbit garanted bandwidth on the R2-R3, but without limit (rate 32kbit, ceil 2mbit) The congested link is between R2 and R3.

...played around the last 2 weeks. I''m quite confident - in theory - what''s possible and the basic difference between the queuing disciplines. We''re using a Fedora Core 3 box as Gateway (iptables,tc,iproute2 with NAT). Clients are coming in via eth1 and outgouing traffic (2Mbit/s SDSL) through eth0. So we would like to enable bandwidth limitation per-user, so i just used several scripts (htp from sourceforge,cbq.init ,wondershaper etc). (Each client: Downstream max 128kbit/s, Upstream max 90kbit/s) Shaping is working fine if i mark this specific source with a iptables r...
