Dzien Dobry Is there some error witch iproute2-050929.tar.gz becouse when i compile I don''t get tc I have kernel 2.6.12.3 this is my log with compile # make make[1]: Entering directory `/home/src/a/04102005/iproute2-050929/lib'' gcc -D_GNU_SOURCE -O2 -Wstrict-prototypes -Wall -I../include -DRESOLVE_HOSTNAMES -c -o ll_map.o ll_map.c gcc -D_GNU_SOURCE -O2 -Wstrict-prototypes

Hi, I have a box with RH 7,2 upgraded to Fedora Core 1. with: kernel 2.4.26 iptables 1.2.9 gcc 3.2.2 In this momment I''m using a binary TC version, but when I try to compile, get errors in Make process. Any hints ? Bests. Andres. ----> iproute2-2.4.7-now-ss010824.tar.gz make[1]: Cambiando a directorio `/usr/local/src/iproute2/lib'' gcc -D_GNU_SOURCE -O2

Hello, I am trying to compile iproute2 but something does not work when linking with libdb. This is what I am using: - iproute2-ss050607 - linux 2.4.22 - make 3.79.1 - gcc 2.95.3 - ld 2.15 When I type make, it ends somewhere in ./misc with the following error message: make output starts here: gcc -D_GNU_SOURCE -O2 -Wstrict-prototypes -Wall -I../include -DRESOLVE_HOSTNAMES -DCONFIG_GACT

Hi, i''m just new here, i''m searching for how to compile tc (if i''ve understood correctly, i must compile the whole iproute2 thing). So i did like the read me file said: ------ 1. Look at start of Makefile and set correct values for: KERNEL_INCLUDE ----- i did that, and then i doesn''t understand a damn thing about the reste of the the 1st step about ADDLIB

Hello Lartc''s users, This is my first contact. I''m trying to implement a new queue discipline based on bfifo schedule. I search on internet but there are some problem(s) that I don''t Know how to solve them and that''s why I''m here asking for your help. Well, These were my steps for the implementation: - Put the new qdisc routine

Hi, I am attaching the patch for tc_class.c file in ./tc directory of iproute2 lastest version. This patch is to avoid segfault when listing classes. It happends only when using PRIO qdisc. I didn''t look why exactly it segfaults (guess becasue PRIO is classless), but this patch at least prevents it, so you can run the command and look what is happening to other classes. cd to iproute2

I''m streaming audio over a WAN that is 1.5Mbit/s. The audio has to go both ways and can be over tcp or udp. The manufacturers recommend udp as it has less overhead but has a higher chance of dropping out. The audio requires 130-200kbit/s in each direction for a combined 260-400kbit/s. I have two transparent bridges on either side of the WAN to do traffic control. I split it so

Hello. I have got strange problem with tc utility (iproute2-ss001007) on linux 2.4.18. No matter what rules i am going to test, the resul of ''tc class ls/show'' is always the same : ATSLite ()# tc -s class ls dev eth1 do_page_fault() #2: sending SIGSEGV to tc for illegal read access from 00000000 (epc == 00000000, ra == 00408750) Segmentation fault tc -s qdisc ls , tc -s filter

Hello all! I have a small LAN at home and when someone starts to download (only one), interractive traffic (www, chat and online games) is impossible with standard kernel queues setup... So I started to shape. My ISP gives me a 512 kbits link to the Internet and a 100 Mbits link to some of the other big ISPs in my country. If I set the rate of the parent htb qdisc at 512 kbits, I will never use

I have linux box (does nat and firewall for small network) connected to dsl. I want to set priorities for protocols (that nothing could disturb web browsing). This is my rules (eth0 connected to internet): /sbin/tc qdisc del dev eth0 root /sbin/tc qdisc add dev eth0 root handle 1 htb default 30 r2q 100 /sbin/tc class add dev eth0 parent 1: classid 1:2 htb rate 900Kbit burst 15k /sbin/tc class

Hi all, I am having some fun with traffic shaping, and have run into an interesting situation. Here is South Africa, most internet links are heavily oversubscribed, which means that in most cases the local link is _not_ the bottleneck, and shaping on the local link does not help that much... Does anybody have some tips on shaping such links? How can you get interractive traffic if you

Hi to all, i''m following this guide (http://www.opalsoft.net/qos/DS-28.htm), is very detailed, but i''m a bit confused about queuing disciplinse of leaf classes. In this guide the author uses PFIFO (see the scheme that i attached at message) in this way: # tc class add dev eth0 parent 1:21 handle 210: pfifo lmit 10 # tc class add dev eth0 parent 1:22 handle 220: pfifo lmit 10 #

Hi list, playing around with HTB showed that it may introduces pretty much latency for our setup. Docum.org says the following: "The default qdisc added to a htb class is pfifo_fast qdisc. The size of the qdisc is the device queue length and this is 100 packets for an ethernet device. So if you want to have a shorter queue, you have to add a shorter qdisc to the htb qdisc." Can

That "program" will be detected by your ISP within a day or so, determined to be a virus, and your service will get disconnected...which n turn will not help your latency or jitter at all. VoIP can tolerate a fair amount of latency; latency over about 100ms is heard as a perceptible delay resulting in a connection that appears to be half duplex. Jitter, on the other had, is the real

Dear LATRC and devotees, I have developed some Linux queueing disciplines. I developed them for my masters project. You are free to use or distribute my work. Here is the abstract from my dissertation:- This is a project to implement a Mice and Elephants queuing discipline on Linux. My project has three aims. The first aim was to produce a prototype Mice and Elephants router

Hello, I''ve just recently started to use IMQ and I got puzzled after seeing the imq usage example on the linuximq.net site: It was something like this: tc qdisc add dev imq0 handle 1: root htb default 1 tc class add dev imq0 parent 1: classid 1:1 htb rate 1mbit tc qdisc add dev imq0 parent 1:1 handle 10: htb default 5 tc class add dev imq0 parent 10: classid 10:1 htb rate 256kbit

In the real world (or at least in my world) we use undersubscribed internet connections that come with a service level agreement (SLA) that guarantees that the jitter, delay, and packet loss with be within defined parameters in the service agreement. With most DSL and Cable you will not get a SLA, with the cheapest T1s you might get one, but the only penalty to the ISP if they do not meet is a

For some time now im trying to get to know what causes such configuration of QOS (kernel 2.4.25-2.4.28 + IMQ patch and ofcourse wrr): -- WRR_MAX_CLASSES=200 DEV_IN=imq0 ifconfig $DEV_IN down ifconfig $DEV_IN up tc qdisc add dev ${DEV_IN} handle 1:0 root htb default 10 tc class add dev ${DEV_IN} parent 1:0 classid 1:10 htb rate 1000kbit burst 1kbit prio 1 tc qdisc add dev ${DEV_IN} parent 1:10
