similar to: Fair bandwidth oversubscribing ? How with HTB ?

What is the cause for such a message while running kernel 2.6.1 on RH9 ? Neighbour table overflow. NET: 282 messages suppressed. Neighbour table overflow.

Hi All, Does anyone know of a way to limit the speed of *individual* TCP sessions, but without placing any overall bandwidth limits, and without requiring an explicit QoS entry for every ip address the machine is communicating with ? The scenario is a mailserver - say you want to limit individual TCP sessions (pop3, smtp etc) to no more than 512Kbit so that an individual session

now, i''m learning and try to read a lot of article about tc command in linux for setting traffic shaper. but i''m doubt about In the theory about tc command ... In general, we define class under root qdisc but Is it can be possible ???? If we define another qdisc under root qdisc, Can i do it? because i have just read tc command syntax and i found this point ... syntax: tc qdisc

Hi asa, You can make a script to ping your internet gateway every 5 minutes and if it´s down it automatically switch the default route do gateway 2. You set a script to run x time with cron job.

Hi, I''m using kernel 2.4.20 and like to use Stephen Hemminger ''s packet delay scheduler patch the patch is there : http://mailman.ds9a.nl/pipermail/lartc/2004q1/012112.html can anyone explain me how to apply it ?

Hi all, I''m having a hell of a time getting my IFB to work. I know I''ve done this before, so I''m missing something stupid. Can anybody tell me what it might be? Configs as follows: -------- #!/bin/sh modprobe ifb numifbs=1000 modprobe act_mirred modprobe 8021q brctl addbr br0 brctl setfd br0 0 brctl stp br0 off brctl addif br0 eth1 brctl addif br0 eth2 ifconfig eth1

This patch changes HTB''s class storage from hash+lists to a two-level linear array, so it can do constant time (O(1)) class lookup by classid. It improves scalability for large number of classes. Without the patch, ~14k htb classes can starve a Xeon-3.2 at only 15kpps, using most of it''s cycles traversing lists in htb_find(). The patch eliminates this problem, and has a

I am investigating changing our broadband bandwidth control scripts over to HFSC. What I would like to accomplish is this: { * DOWNLOAD * I need a download class for each user (we''ll call it Class 1) that offers a minimum of lets say 384Kbps and a maximum of 1.5Mbps. The rates between 384Kbps and 1.5Mbps should be shared among all users. Each user should always be able to get at

I was trying to install iproute2-2.2.4. I get an error when i run the makefile. I get a parse error in /usr/include/arpa/inet.h. Can someone help me?

Hi all, I''m sure I''m soing something wrong here. I am trying to set up a rate limit inside another rate limit. eg. I have a 512K rate limit on a particular VLAN. I am using an IFB so that packets passing through the bridge are counted at each port.(ie the throughput is limited to 512K, not just the traffic in one direction.) This part works OK, but I also want to limit a

G''Day I would like to be able to use my VOIP telephone over a saturated ADSL link whilst enjoying optimum audio quality and utilising all of the bandwidth I pay for. It is about this situation that I write. HFSC appears to be the queueing discipline of choice for VOIP. In order for this to work, though, do I have to account for the ATM overhead in the small VOIP packets by defining my

I''m using HFSC to limit bandwidth for our wireless customers. However, I''d also like the bandwidth prioritized based on packet type. This is what I''m trying right now, and I''d just like some input from anyone out there knowledgeable in this on whether it does what I want it to do: Eth1 -> HFSC ........|-> HFSC (User1) (Min 512 Kb, Max 1024 Kb, Burst 1536

Hi, A thought for the list. As I mentioned in another posting, there are a lot of QoS mechanisms out there. Linux supports some, but not all. Some patchsets add others, but don''t work for all kernels. There are also userland implementations, usually sitting in software routers, but there are other packages. Would it be helpful if I worked on a table of what''s out there for

i doubt about ruleset in mastershaper demo about why use hfsc at leaf class but inner class use htb??? how different for manage traffic like it???? /bin/false qdisc add dev eth1 handle 1: root htb default 1 /bin/false class add dev eth1 parent 1: classid 1:1 htb rate 2048Kbit ######### Incoming Rules ######### chain HB /bin/false class add dev eth1 parent 1:1 classid 1:21 htb rate 128Kbit ceil

Hi Couple months ago I started to have a strange problem with HTB. My setup is Fedora Core 2 + Pentium 2 233 + 128 MB of ram and its serving as a router. For some time since going to kernel 2.6 my HTB QoS Stalls for couple seconds, every couple minutes. If the connection load is bigger the stalling is more frequent and takes longer. I isolated the problem to be with HTB (CBQ works fine). The

Hello! I need assistance to solve my problem related to traffic shaping based on the user ids. The problem: each unix user (of the linux host) has to be limited with incoming channel (internet) bandwidth. I need this to implement internet access solution based on ltsp (http://www.ltsp.org). As far as I know the best way to shape traffic in linux is CBQ. But there is no filter based on unix

Hello all. I''ve been struggling to QoS VoIP at our site and have a successful implementation at this point. Basically I had to set aside enough bandwidth for VoIP by placing all other traffic behind an HTB (multiple classes and queues behind it). Everything is fine. Here''s the diagram: ------- | eth | ------- | --------

While I''m thinking about that review of howto changes, here are a few other responses about things I don''t believe. I''ll be interested in more info if anyone has any. ==== [from new doc] Besides being classful, CBQ is also a shaper and it is in that aspect that it really doesn''t work very well. It should work like this. I''ve not noticed that it

Dear List, Sorry for the dublicated email but I couldn''t get any answer.
