Hi all, I have setup two multipath route tables on my system for doing failover routing, What I want it''s that if GW at route1 of the MP is dead, traffic goes by route2, for doing that I have created the multipath routes as follows: ip route add table mail.traffic proto static nexthop via ${GW1} dev eth1 weight 1 nexthop via ${GW2} dev eth1 weight 250 But it does not run as I

Hi! I am learning tcng without having experiance of tc and I am trying to build something that shall schedule traffic dependent on the value in the IPv4 packets ip_ttl field. I have read the tcng reference manual and cannot find information about forwarding. Is it possible to farward packets from ingress to egress without sending them upwards in layers?

Hi all, this is really not really very easy to understand, or, to get in. Well, I''ve the following configuration on the router box: LAN - interface: eth0 - network: 192.168.2.5/24 - bandwidth: 100Mbit/s INET interface - interface: ppp0 - network: .dynamic.ip./0 - bandwidth: DOWN=1536kbit/s and UP=256kbit/s the LAN interface is to serve 6 other clients with internet and

Hi all, It is my understanding that with HTB, the rate and the ceiling are divided over the elements of the class. E.g. using a rate of 100 kb and a ceiling of 2000 kb for a class with 10 elements on a 100Mb NIC, the effect of the ceiling will be that if all elements are generating their maximimum possible trafic they will be effectively limited to ~ ceiling / number of elements, in this case

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

Hi all I''m new to this list, but not exactly to iproute stuff. I''d like to solve a specific problem with bandwidth coming from different external sources towards the internal network (also the other way around, but I figure that''s not so much a problem, since that is egress traffic shaping). The network looks like this: internet ------ ISP-------[shaping/router]

Hi I''m completely stuck with the tcng language - I assume there must be some way to arrange queues hierachically like eth1 | TBF | PRIO / \ class class but my attempt (below) produces a "inferno.tc:8: qdisc "tbf" has no classes near "prio"" when run through tcc. dev eth1 { egress { tbf (rate 128kbps, burst 64kb,

Hi all I started playing with tcng to generate my tc rules, but I have some difficulty implementing my rules... The script below generates an error: # Device eth0 tc qdisc add dev eth0 ingress beginner.tc:2: don''t know how to build meter for this The script is below, I changed the real IP numbers for XXs and YYs, since it doesn''t really matter what they are. eth0 is the

ingress can be used to control the incoming packet, such as: tc qdisc add dev eth0 handle ffff: ingress tc filter add dev eth0 parent ffff: protocol ip prio 5 u32 match ip src 172.16.1.11 police rate 10kbit burst 10k drop flowid :1 tc filter add dev eth0 parent ffff: protocol ip prio 5 u32 match ip src 172.16.1.22 police rate 10kbit burst 10k drop flowid :2 first ,I do not sure these method can

Hi, I am trying to do both ingress and egress bandwidth management on a bridge. eth0 is the WAN interface. IPTraf shows that the following script is running successfully and it limits bandwidth both ways to 256 KB However when I want to see the statistics using tc - it only shows me stats for htb class and not for ingress class. The tc output is as follows: tc -s -d class show dev eth0 class

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 --

Hello all, I am trying to set up a simple htb based system, where packets with source ip 10.0.0.1 should have their own class. I plan to use tcng to set it up easier. Is there something wrong in my tcng file ? ~/tcng$ cat htb /* */ #include "fields.tc" #include "ports.tc" dev eth0 { htb ( ) { class ( rate 600kbps, ceil 600kbps ) {

//Just to not forget eth0 is WAN and eth1 is LAN . The box is NATing my lan. I configured tcng to shape both download and upload and i got connection loss again. Maybe it is my script fault or it is something bad with packets marking . this is how i mark outgoing packets iptables -t mangle -A MYSHAPER-OUT -p tcp -s 192.168.1.23 -j MARK --set-mark $ip and this part of my script which is intented

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 everyone. I''m working on a problem since some days. I have a linux router with about 100 ppp interfaces. Each interface should bei limited to an individual bandwidth of 1024kbit, 2048kbit or 3096kbit. Up AND downstream. (let''s say for example 1024kbit upstream and 1024kbit downstream) The reason for this problem: I have to limit users to their booked bandwidth, because

Hi All, I''m trying to do some traffic shaping on an ethernet bridge. Currently, I have the following setup working: ifconfig eth0 down brctl addbr br0 brctl addif br0 eth0 brctl addif br0 eth1 brctl stp br0 off ifconfig eth0 0.0.0.0 up ifconfig eth1 0.0.0.0 up ifconfig br0 up This creates a bridge consisting of eth0 and eth1. So far so good. I now want to use tc to shape traffic

Guys Considering the festive season is upon us, thanks to everyone contributing to the list and helping all the readers with your great input! I don''t want to mention names, I''ll most certainly leave someone out. With this mail I''d like to test some theory on bandwidth management, with my own successes and failures during the past year. Sharing a link between 200

hi all. i am currently now serving PPPoE in my area. i had a script generated from tcng that worked perfectly before i started serving PPPoE. the issue is not in the script it self BUT in that "tc" code is not shaping on the ethernet anymore BUT INSTEAD on the pppX devices. I tested it and talking jargon, what should i do? The issue is that for each PPPoE login, PPPoE-server

Hi all, Can someone please help with a tcng setup? I have played with tc and tcng in the past, and now would like to get some serious rules in place. However, I have a difficulty in setting them up. My setup is as follows: One machine working as a firewall: eth0 is the interface connected to a 512K DSL line eth1 is connected to a LAN eth2 is connected to another LAN, a bit like a DMZ eth1 and

Here''s the scenario: - 4 NIC''s; 1 Upstream, 3 subscribers each with different rates. NIC-1: NO CAP simply 100mbit I want to cap the traffic on each of the subscriber NIC''s to a specific rate i.e.: - NIC-2: 8mbit - NIC-3: 5mbit - NIC-4: 3mbit Just to summarize, ALL I''m trying to do is limit the bandwidth on each NIC (ingress & egress) whether it
