[LARTC] Citrix and QoS
Thanks to all the content from the archives and the HOWTO, I've got a QoS bridge running, based off the Dante script http://www.compsci.lyon.edu/mcritch/dante/ --> http://www.compsci.lyon.edu/mcritch/dante/shape.sh.eth0 While we are experiencing a marked improvement in Citrix consistency, I still feel there is room for improvement. Citrix sends a LOT of small packets. It is basically a very thin stream. The only thing I can really see benefitting us more would be to break up large packets so that Citrix packets don't wait for large packets to complete sending. We also run H323, and QoS has helped immensely in eliminating dropped packets and interference between H323 and the more important (lower priority) Citrix class. Would lowering the MTU size be safe in order to force packets to be fragmented? What kind of negative impacts should I expect / look for with this? I'm not sure what the packet size our H323 units use... I guess I could use Ethereal to check it out. May depend on settings as well. Any comments appreciated. Thanks!
[LARTC] limiting the bandwidth for *each* ip in some class
hello all, i got my htb running and controlling my bandwidth right, but i have a doubt. i configured HTB to limit my class 192.168.0.0/24 to 128kbit. but i want 128kbit for *each* machine on this class, and not for the entire class. when 2 machines in 192.168.0.0/24 are downloading one file, they share the 128kbit bandwidth between them, using 64kbit for each. why i can get all machine on this class using 128kbit without share this link? thanks ___ Yahoo!

[LARTC] Finally: A working case of two adsl load balance
First of all i wanna thanks Christoph Simon for the support. Only after his reply to my email i could see the real solution to the problem (Valeu mesmo cara... me ajudou pra caramba! Fico te devendo essa!) :) Here is what i learned in a month of research: I tried A LOT of things to do load balance, including the one at LARTC homepage. The only tutorial that REALLY works in my case is the Christoph Simon at http://www.ssi.bg/~ja/nano.txt Maybe LARTC can replace the erroneous tutorial at http://lartc.org/howto/lartc.rpdb.multiple-links.html with the nano.txt. I will not write a tutorial, first of all cause my english is very bad. Second because the nano.txt tutorial can do the trick. I will just give some hints i used here. First of all the load balance DOESN´T work without the Julian Anastasov route patch. You can get it at: http://www.ssi.bg/~ja/#routes So don´t be lazy, get the kernel source code, aplly the patch and compile the kernel. Pay attention to your nat configuration. In the first attempt I had problems cause i forgot to mask the nated ips on the postrouting table (this command is the last on my example below). I used the ip adress of the external interface, not the mask for the external network (nano.txt tutorial gives the 2 options...) Be sure that you don´t have a default route on your main table. If u have any, delete it! I have a linux box with: - Kernel 2.6.3 with Julian Anastasov patch to kernel 2.6.0- 2.6.3 http://www.ssi.bg/~ja/routes-2.6.0-test11-10.diff - iproute2-ss010824 - 4 ethernet cards: eth0 - internal lan ip range 192.168.1.x eth1 - internal lan ip range 192.168.2.x eth2 (ppp0) - external adsl with 600 Kb/sec down and 300 Kb/sec up eth3 (ppp1) - external adsl with 600 Kb/sec down and 300 Kb/sec up I have nat and my 2 lan access the internet using the linux box as gateway.

I can play online games without problems. MSN/ICQ remains connected all the time using the same ip address. No packet loss problems.The two 600/300 lines really looks very similar to a 1200/600 line. It´s really wonderful. I hope this can help someone. The load balance isn´t so hard to do when you know which commands you really need. I did it, why can´t you do it too? :) Fernando Favero [EMAIL PROTECTED] ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
[LARTC] netem usage example
I'm trying to setup a netem delay with no luck (using iproute2-2.6.8, compilation broke during arpd compile, so I use the tc binary in the tc/ subdir, there's also a q_netem.so there). kernel is 2.6.8.1, compile with CPU cycle counter as time reference. I was using sch_delay of 2.6.7 happily with something like: tc qdisc add dev eth0 root 1: delay latency 1ms rate 35M now I use: tc qdisc add dev eth0 root netem latency 1ms and it complain about "unknown qdisc netem" do you have usage example with the new netem "scheduler"? thanks ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
Re: [LARTC] RE: [LARTC] Load Balance simply doesn´t work...
Hello,
>From the looks of it you have the IP Network incorrect, You need to set
this to your Network... for example ..
ip route add 23.215.4.0/26 dev eth2 src 23.215.4.61 table T2
23.215.4.0 is the network address, because 23.215.4.1 is my gateway for
this interface (Router). If you still have a hard time with it .. You
can post your Netmask and GW and I should be able to figure it out for
you. There may be a way to do it from your IP address, but I had
subnetting and aren't very good at it :)
ip route add 212.71.142.210/29 dev eth1 src 212.71.142.210 table 10

[LARTC] ANNOUNCE: Linux QoS Library (LQL) 0.5.0
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 lot more testing done before I made a public release but I decided to go with the release early, release often strategy. * 86% API documentation coverage. A lot of the undocumented API is for the U32 classifier implementation which I am not that fond of. I think this API will change quite a bit. * What LQL really needs is much more testing in larger applications. * I make absolutely no promises that any of the API will be stable. I expect the API to change as larger programs are built with it and new limitations (and bugs) are found. Please see http://www.coverfire.com/lql/ for more information.
