similar to: Shapping IP Traffic on an Embedded System (Non Linux)

Hi, I am the network administrator of my company, I know quite well Windows networking and a few about Linux and its amazing routing and QOS capabilities. Right now, we have a bustable T1, which mean that the bill increase with out T1 use. I have decided to find a way to shape the traffic so I can stay at a raisonable speed of 256 kb/s (Up/down) on my T1. I have linux gateway with 2 nics behind a

Hi there! I''ve using HTB for a while and now I an faced with a ''problem''. How hierarchical is HTB? Let''s say I have this 3 layer HTB setup: root class 1: (rate=100, ceil=100) 1: children classes 1:10 (30,100) and 1:20 (70,100) 1:10 children classes 1:100 (10,100) and 1:101 (20,100) 1:20 children classes 1:200 (30,100) and 1:201 (70,100) I managed to have

Hi, I''m trying to make run a simple shaping *through HTB*. I have compiled a new kernel 2.4.21. First command from http://luxik.cdi.cz/~devik/qos/htb/manual/userg.htm said: # tc qdisc add dev eth0 root handle 1: htb default 12 RTNETLINK answers: Invalid argument I tryed both standard tc from Debian stable and http://luxik.cdi.cz/~devik/qos/htb/v2/tc.gz this one... I tryed

Witold Szczerba spent his time evaluating fairness of borrowing. His troubles inspired me enough to analyze the problem: When a class changes from yellow to green it disconnects itself from parent''s feedlist. Unfortunately it resets feed pointer to the first child. I created a patch where the class uses classid to remember its position in the feedlist. The patch for 2.4.24 and hopefully

Hello all, I´ve read http://lartc.org/howto/ and now i am just confused, i think my skills with linux are not very good, so asking for help. I have a linux box with two ethernets cards eth0(gateway 1mb) with is the host for some sites and emails and eth1(nat interface) with provide internet acess to other 5 pcs. I would like to limit the bandwith 512 k for the eth0 and 512 k for eth1 however

Hello, I think the BUG_TRAP() in the htb_dequeue_tree() is wrong. First it checks if the class pointer "cl" is NULL, which is obviously right. But I do not understand why we also check whenever the queue length of the leaf queue is zero "cl->un.leaf.q->q.qlen". I would have put that in the expression of the "if" statements that comes afterwards. A queue

Hi, I am new to tc, please forgive me for simple question. I have linux 2.4 in my routers, I would like to use HTB. I have downloaded binary code from http://luxik.cdi.cz/~devik/qos/htb/#source, (tc.gz), but I could not open the file. Is there any other place I can get binary code for HTB. Also if you can give some direction how to patch it, it will be really helpful. Thanks in advance Omer

Hello ALL, is there a way to have a device independent qdisc, or a qdisc on some kind of virtuall interface? Background: I have a 5-Interface-Router with one Internet-Uplink. The Router should connect the clients on the other Interfaces to the Internet and to each other client. As i understood the hole TC stuff i can only get influence of outgoing traffic. In my case i can reduce the traffic of

Can I use the same SFQ queue dicipline for all the classe in a CBQ or HBT system?

Hi, I''m a bit confused with the priority of different classes with HTB. How it will be? Will the class with lowest no: have maximum priority? Any help is most appreciated, Thanks in advance, Sanjeev -- ______________________________________________ Check out the latest SMS services @ http://www.linuxmail.org This allows you to send and receive SMS through your mailbox.

Hello, I''d like to try out HTB for traffic shaping. I have a test machine with Redhat 7.2 (kernel 2.4.10), I''ve downloaded kernel 2.4.17, applied the patch from http://luxik.cdi.cz/~devik/qos/htb/, recompiled the kernel (checked the option to use HTB in make menuconfig), and rebooted with the new kernel. When I try to add some rules with HTB (f.i. tc qdisc add dev eth0 root

I would like to differentiate incoming traffic streams to guarantee minimum bandwidth to some services. However, as per the Adv-Routing-HOWTO it appears that only outgoing traffic can be shaped. Is this correct or is there a way of shaping incoming traffic? The problem could possibly be overcome if there is a way of routing traffic through a virtual host. Any tips on how to go about that? --

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everybody! I am wondering, whether it is possible to have qdiscs and classes as childs of a class or not. take the following example: ~ ,----- ~ | class 1:1 ~ | / \ ~ | / \ ~ | / \ ~ | class 1:10 qdisc 11: ~ | / \ ~ | ...

Hi all :) I think that this issue has already been discussed on this list, but google didn''t find anything interesting, so I''m bringing the subject again. The output of "tc" uses "b" meaning "byte" and "bit" for "bit". The "official" suffixes for those units are "B" and "b", respectively,

I cannot get HTB to function properly. Most classes transmit more than their ceiling, more than any reasonable burst would allow. I have reviewed my script several times but I can''t find anything out of place. The setup is as standard as it gets: one HTB root qdisc, a small tree of HTB classes, one SFQ qdisc for each leaf HTB class. To illustrate the problem, here is non-leaf HTB

Hello! I need to switch from htb2 to htb3, because of speed issues (for me, htb2 is unable to handle more then 100mbit duplex with ~550 classes), kernel profiling shows htb_dequeue_prio at 1st place with 3x isolation. So, I''ve moved from 2.4.19 to 2.4.25 kernel (hi-pac for classification/marking and htb3 for queueing), and traffic rate drop from 100 to 20mbit. What can be wrong? The
