I''m trying to do some very simple rate-shaping on an interface. I want to limit my 100baseT interface to 7 megs both ingress and egress of the interface. I''ve been hacking my way through the documentation and some examples and I''ve come up with the following configuration for tcng that seems to do what I want. I''m curious if some of the other experts out

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

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?

I am successfully running ingress (IMQ) and egress (HTB) shaping on a bridge. Is there any way to combine and share the bandwidth between ingress and egress? Example: I have set up www service for egress at 128 KB and ingress at 256 KB. The shaping on them works fine separately. However, I want to create a single virtual pipe for www traffic and limit both ingress and egress combined to 256 KB.

I''ve followed this list for quite a long time and have even posted a couple of times. I used the early versions of IMQ from Devik (I think that was his name), and it worked well. I only ever got the chance to implement it in my test environment. I now need to implement it in my production environment. My Linux core router has nine interfaces and has a 27 megabit connection to the

[I sent this earlier but I guess the list is subscriber-only?] I just set up wondershaper, it has a simple filter on the downstream direction to limit the bandwidth usage: tc qdisc add dev $DEV handle ffff: ingress tc filter add dev $DEV parent ffff: protocol ip prio 50 u32 match ip src \ 0.0.0.0/0 police rate ${DOWNLINK}kbit burst 10k drop flowid :1 This is effective but is there any way to

I have two interfaces, eth0 and eth1 but i can''t discern the egress traffic than ingress traffic. I need to apply htb qdisc in both directions, and I read that I need the IMQ patch to do this, because in ingress qdisc i can''t apply htb qdisc...but where is the ingress qdisc? affect the traffic that goes from eth0 to eth1 or is for the traffic that goes from eth1 to eth0?

Hi, I have typical situation, local LAN with private addresses, translated via NAT to internet. I need to shape ingress traffic (from internet to local LAN) in several HTB queues accorting to destination (private not public) IP. So I need mark packets to divide them to corresponding queue. According to http://www.docum.org/stef.coene/qos/kptd/ I thing I have only one way how to do it, because

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

How to use IFB as replacement of IMQ There is not much documentation about it Please explain with example -- Failure seldom stops you. What stops you is the fear of failure. _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

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 --

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

Objective: All web traffic originating from my proxy server should be forwarded through interface eth2 instead of the default eth0. The reply should take the same path back to the proxy server. Problem: On the return bout, the kernel doesn''t pass the packet to the higher layers. The reply seems to be getting tossed away between PREROUTING and INPUT Netfilter chains.

Dear list, I want to rate-limit a couple of customers in both up and down directions. They get a different speed for traffic staying on our network than for traffic towards/from the internet, so that''s a master class and 2 child classes per customer per interface. I made a test setup with cbq which worked, but wasn''t too reliable I measured a tolerance of about 30%. I read

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

Hello all, I have been doing a lot of archive searching over the last week reading posts on IMQ and it''s apparent stability / instability. I have seen a number of posts about it not being maintained as well. Can anyone talk to me about IMQ''s stability in a heavy throughput environment (20 Mbps) and what was causing IMQ to fail if you know. Thanks, Mike

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 ) {

Hi, I have a Debian that is connected to Internet in eth0, and to a LAN in eth1. I wanted to control traffic with HTB, dividing it depending on what kind of traffic is (Mail, Application Server and others). Would it be good to use HTB qdisc in eth0 egress to control outgoing traffic and HTB qdisc in eth1 egress to control incoming traffic? Or the only way to control incoming traffic is with eth0
