hi i am running Debian/GNU Linux with 2.4.26 kernel and radius server my kernel conf looks like this <*> Packet socket [ ] Packet socket: mmapped IO < > Netlink device emulation [*] Network packet filtering (replaces ipchains) [*] Network packet filtering debugging [ ] Socket Filtering <*> Unix domain sockets [*] TCP/IP networking [*] IP: multicasting [*] IP: advanced

Hi, all I am interested in Linux related QoS, especially PRIO queue discipline (qdisc). I test some experiments about PRIO qdisc. Host A ------ Router A --- Router B --- Host C | 1Gbps | Host B ---------+ +-------- Host D flow 1 : Host A -> Host C (TCP) flow 2 : Host B -> Host D (UDP) priority 1 queue (pfifo, size 1000 packets ) : flow 1 priority 2

Hi. I did send this to `jaazz@post.cz'', but I suspect the list is a more appropriate/useful place for it. It''s a question about Michal Charvat''s QoS extension to Net-SNMP. When I look at the MIB entries for the QoS handles, I get something like this - enterprises.qos.qosObjectTable.qosObject.qosHandle.0.0 = Gauge32: 0

Hi, I''m trying to configure QOS , but I''m don''t have success. My files: #/etc/shorewall/tcdevices #INTERFACE IN-BANDWITH OUT-BANDWIDTH eth0 256kbit 256kbit eth1 256kbit 256kbit eth2 256kbit 256kbit #/etc/shorewall/tcclasses #INTERFACE MARK RATE CEIL PRIORITY OPTIONS eth1

Hiya, i have a squid-2.5.4 transparent proxy working in http accelerator mode (i.e. web servers are behind the squid, and all www records point to the squid IP) and i want to implement some sort of bandwidth management so, for example, any given hosted website/server won''t eat more than let''s say 1Mbit of upstream bandwidth, i have recompiled squid using Patrick Mchardy

Hi Guys After googling a little I couldn''t find the correct answer.. When I use : tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip dst 192.168.0.11 flowid 1:30 , I can shape traffic to 1:30.( works like a charm) Now instead tc filter I would like to use CLASSIFY as below: iptables -t mangle -A POSTROUTING -o eth0 -d 192.168.0.5 -j CLASSIFY --set-class 1:30 but when I

I''m playing with the rather excellent QOS script from Alexander Clouter at http://digriz.org.uk/jdg-qos-script/ So far I am really impressed with it - a very impressive example of the power of linux QOS rules (has pretty much everything in it from the LARTC Howto!) However, the instructions hint that "for QoS to affect locally generated traffic in a non ethernet bridge setup

The Linux QoS Library (LQL) provides a GPL licensed, GObject based C API to manipulate the network queueing disciplines, classes and classifiers in the Linux kernel. LQL does not use the TC command as a back-end. Instead, LQL communicates with the Linux kernel via Netlink sockets the same way TC does. 0.5.0 2004-08-30 ----- * Initial public release. * I wanted to get 100% API doc coverage and a

Hello First thanks for the answers I have received from the list!! I have now a working qos configuration which bases of the lartc howto capitel 15.10. One Problem I have is that I have limited the upload stream to 100kps because my upstream is only 128kbps. Everything works fine EXCEPT Voip. I have a VoiP phone which is connected on the same net as the adsl modem BUT does not use upstream it

There are two Linux routers, a 64K leased line is used to connect these two machines. Now, we would like to run Voice over IP between two machines. We have to run QoS and tag voice packet''s TOS field, otherwise, the voice quality is terrible if we transfer file and make voice call at the same time. I am not familiar with tc in Linux. But I have copied a script from LARTC archives. If

Hi, Steff. Next file are not found on your website: http://www.docum.org/stef.coene/qos/tc-snmp//example/html/mrtg.cfg can you post it ? Thank you !

Hello all, I have set my QoS solution and now I am facing a little problem... When I ping to my server it has some lost packages: Estatísticas do Ping para 172.30.0.1: Pacotes: SENDED = 1029, RETURNED = 880, LOST = 149 (14% de perda), Aproximar um número redondo de vezes em milissegundos: Mínimo = 0ms, Máximo = 686ms, Média = 105ms If I disable my QoS ping stats to be ok. I even have

Hello, I''ve got somes questions about Bridge and QOS ... I''ve got a serveur with 2 interfaces eth0,eth1 inside br0 bridge ... nothing of special ... If I understand all, normally I should configure TC class and qdisc on each physical or use ebtables to manage packets on output ... right ? I''ve attached my qos_script that hsfc and layer7 module. I use only Iptables

Hi, I have what to me is an interesting issue. I am wanting to prioritize (QoS) traffic that will be passing through an IPSec (OpenS/WAN) VPN between two (identical) Linux routers. I know that I can apply the IPSec patches (1-4) to the kernel and IPTables (if they are not already applied by now) filter traffic before and after IPSec encapsulation. My problem is that I don''t know

hello folks, this is my first post to that list. so I hope I am not completely OT here :-) reading the (excellent!) lartc and then writing my own qos-script I have still some open questions which I will try to formulate now: - "Now we can optionally attach queuing disciplines to the leaf classes. If none is specified the default is pfifo." - I can''t find info about Pfifo.

Hi I''m on my last year and I''m writing my final project about QoS support in Linux 2.4 kernels and, in general, about QoS in Linux OS. My professor asked me about future of QoS in Linux. And I asking you :) What are the difference between QoS subsystem in 2.4 and 2.6 kernels? What are the future plans for evolution of QoS support in Linux. -- Pozdrawiam Marcin

Hello all, As I have promised I am sending my QoS rules. This now works fine with u32 classifier (and parent 1:0 that I could not understand why it did not worked well before). Att, Nataniel Klug ------------------------ #!/bin/sh #------ # Script de QoS Cyber Nett #------ # Nataniel Klug # suporte@cnett.com.br #------ TC="/sbin/tc" IPT="/usr/local/sbin/iptables"

I just wanted to drop a success notice to the list. We always hear the failures, and rarely the successes! ;-) After switching from FC1 and freeS/WAN ipsec to the new native linux 2.6 ipsec (ie: setkey-based) my QoS code suddenly started working properly! Previously, with FC1 and freeS/WAN, I found it impossible and rather buggy (kernel panics!) to get QoS to make any difference at all. My

Hello all, I am trying to configure a linux box to make some QoS into my netowork and, at the same box, control my clients bandwidth. I have this classes created: ---------------------------------------------------------------- UP="eth0" # wan infocontabil DL01="eth2" # lan clientes $TC qdisc del dev $DL01 root 2> /dev/null >

Hello All, I am interested in QoS provided by Linux, when I looked into IP header I came accross ToS field, also while going more into detail about QoS I found that the QoS based on ToS is serviced thru DiffServ which in turn gives more priority to packets with higher value is ToS field, but I am not able to understand when we finally call dev->hard_start_xmit routine of underlying device
