Hi, my shorewall is version 4.0.15 on Debian Lenny. I have 3 following interfaces: eth0 net (4mbit/512kbit) eth1 loc (100mbit) eth2 loc (100mbit) I want to shape traffic from net on two lan interfaces like: - default is 2000mbit for each local interface - if is no traffic on eth1 is 4mbit for eth2 (and vice versa) My tcdevices eth0 4000mbit 512kbit eth1 -

Hi All, I read the advanced networking howto and find a useful way to shape my adsl link. is says: "tc qdisc add dev ppp0 root tbf rate 220kbit latency 50ms burst 1500 [...] Change 220kbit to your uplinks *actual* speed, minus a few percent. If you have a really fast modem, raise ''burst'' a bit. " My adsl''s upload brandwidth is about 120 kbits/sec,

I try use setup traffic shaping with Shorewall-4.0.2 and have fault. When i start Shorewall with tc-files configured i get follow messages: ... RTNETLINK answers: No such file or directory We have an error talking to the kernel ERROR: Command "tc filter add dev eth2 parent ffff: protocol ip prio 50 u32 match ip src 0.0.0.0/0 police rate 500kbit burst 10k drop flowid :1" Failed

I''m trying to set up a shaper that can shape the inbound traffic to around 40 subnets, that hang on 3 different interfaces of the router. As Linux can''t do ingress shaping I''m left with having to set up 3 seperate shapers, one for each internal interface. This is not completely optimal as I''ll have to limit each of the 3 interfaces to 1/3 of the total

Hi, I''m trying to use Shorewall (3.0.6) to accomplish what I thought was going to be fairly simple. Unfortunately, I can''t get the dmz to work correctly, and I''m getting martians logged against the interface at issue. Any help I could get would be greatly appreciated! A picture of my physical setup is attached. I have also attached a shorewall dump. To make a long

Hi all, I tried last week to do traffic shaping on a production system, object of the exercise was simply to throttle the outgoing traffic. tc qdisc add dev eth4 root tbf rate 300mbit burst 300kb latency 50ms But the server became rather instable, crashing repeatedly without anything in the logs. Can anybody spot glaring mistakes in the tc command above, or tell me what I should have done

Hello Please give advice in selecting suitable QoS Solution for our device. It contains one WAN port and a LAN port(4 port switch). The WAN will be connected to an ADSL modem(so we don`t know the bandwidth in advance for the WAN and depends on the ADSL connection taken). We need to give highest priority to the Voice and control the WAN bandwidth to 2Mbps. I tried with the TBF by giving 500kbps

Hello, I''m trying to get lossless VoIP traffic over my 3000k/500k ADSL line. Shaping outgoing traffic is no problem: I set total ceil for outgiong device (ppp0) to 450kbit and put VoIP into highest prio class. Even during full upload the voice is clean on the other end. Now I tried to get the same result for incoming data. I attached HTB to eth1 where the incoming voip traffic is

I''m trying to setup traffic shaping on my linux gateway/router. The system has 3 interfaces: eth0 - My LAN - with IP address 192.168.0.254 eth1 - The ethernet connection to which my ADSL modem is connected. This has a 10.25.x.x IP, more on this later. The ADSL link has an upstream of ~1.2mbit. ppp0 - The PPP connection which is my WAN connection, with a real world IP. The system acts

Hi I would want to use the patch for squid released by patrick mcHardy, but it requires that squid is located on the same machine that does traffic shaping. My configuration is different: i have the screening HDSL router directly connected to a multi-ethernet firewall and the proxy located on a DMZ box. i would want the firewall doing traffic shaping.

Hi, I''m looking for info about IFB devices and how I can use it to incomming traffic shapping. Has IFB any web about it? Do any body known where I can find more info about it? I found this: http://linux-net.osdl.org/index.php/IFB But I can''t stand fine how to use it to allow many ifb''s devices or how to use it with "tc actions". Any help? Thanks --

On a router, there is no need for and IMQ because there is always an egress path. For example: Internet -> eth1 -> iptables -> routing -> ... -> egress qdisc -> eth0 -> LAN LAN -> eth0 -> iptables -> routing -> .... -> egress qdisc -> eth1 -> Internet Local Process / Proxy -> routing -> iptables -> egress qdisc -> eth1/eth0 ->

Hi all I am using a pass trhu router and I need to QoS some clients output by its IP address. The problem is that QoS is due after NATing. Is there some clever way of doing this besides MARKing every packet with some IP hashing in POSTROUTING NAT table? Regards Ethy

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

Hello, Sorry for the many Ccs, but I hope to reach all parties involved. I want to do traffic shaping with NAT and I wanted to do it with IFB instead of IMQ [1]. I tried a lot of things but now I am stuck (and maybe confused). The setup: eth0 eth1 WAN/(Internet) <-> Linux Router <-> LAN Linux router: - does NAT for the LANs - runs local processes

Hello I have 2 class-B networks (172.22.0.0/16 and 172.23.0.0/16, over 130k of ip''s) and need to setup traffic tbf shapers with 64kb/s for each ip from 172.22.0.0/16 and 128kb/s for each ip from 172.23.0.0/16 just read lartc and don''t understand how to use u32 for decreasing number of rules and hashing

I''m trying to set up a traffic control on ingress attaching a egress qdisc to the ifb device. The idea is to use a RED algorithm instead of policing the incoming traffic. After trying with tc-red and not obtaining the expected results, I decided to try with something easier, and use htb as bottleneck: ifconfig ifb0 up tc qdisc del dev $dev ingress tc qdisc del dev ifb0 root tc qdisc add

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 All, I''m using Shorewall 3.0.4 and I''m wondering if it is possible to do traffic shapping on only one interface from a bridge. The firewall has got 3 NIC, eth0, eth1, eth2. eth0 and eth2 are bridged, but if I''m right, when you specify a traffic rate for a link, you do it for the interface. In my case, eth0 and eth2 do not appear in the interface file, but it is
