HOWTO: Bandwidth limiting

[tnt]

This one creates p2p.rrd database:

Anyone that can see what is wrong with my script?

I have two nics. One is eth0 and is connected to internet and one is eth1 and is connected to my internal lan. These two are brdiged as br0 (maybe that what is wrong?)

Anyway here is the script:

[kaksi]

It seem like the bridge is the problem. Cause when I set the interface to be br0 on the iptables parts it works... Hmmm so iptables can not see of the package belongs to eth1 or eth0 when they are bridges as br0 but tc can...

[kaksi]

I seem to have problem with l7-filter. I have emerged l7-filter and l7-protocol and iptables with l7-support.

But I still can not get any result from it. I have this code to mark ssh packages:

tnt: Can you post the scripts that generate the graphs aswell?

[tnt]

It's little bit messed up, and too long for one post:

Still first script, part 2:

You've asked for my scripts, you've got them...

To the original author, thank you very much for this how to, very well written and very informative.

To everyone, I just have a curiosity question: How much overhead does implementing bandwidth throttling impose on the kernel? Is it just a matter of how many rules you have? Or does it have a fixed penalty as soon as you have one rule, combined with the penalty for each additional rule?

I have a linux gateway that shares the internet connection for my whole home network. I use the following to forward DC++ connections to my machine on the internal network (connected to eth0) that's actually running DC++ (p2p application).

What I want to do is set up bandwidth limiting on my gateway that will limit the upload traffic of that specific box on the inside network.

I use this to let dc++ work on the inside machine:

I changed it over to work on ppp0, still limiting download too however:

Try to use this:

Hi,
I am very new to HTB. In fact this is my first htb script.
Everything works great (a very good tutorial ), but I have 2 questions:

1) It seams that my ftp transfer runs faster than 10kbit. It seams it works with 15kbytes/s... Do you know why? This is not a very accurate measurement. It is the value showed my Total Commander when I transfer a file to my xp box from my linux server.

2) Could anyone explain the following?

class htb 1:20 parent 1:1 leaf 20: prio 2 rate 10Kbit ceil 10Kbit burst 1611b cburst 1611b
Sent 193705 bytes 2836 pkts (dropped 0, overlimits 0 requeues 0)
rate 1291bit 19pps backlog 7p
lended: 2829 borrowed: 0 giants: 0
tokens: -1354518 ctokens: -1354518

my script is:

[tnt]

Probably you use passive ftp and port 20 on the server side is not used...

I tried it the last two days. i don't get some real good shaping to work. why is there no X tool with preconfigured stuff
for ssh,ed2k,etc? - do you know the tool for ms windows called 'cFos' - thats such a klick-yougetit-tool. Maybe
someone can post his entirely firewall-script with l7-filters, because i don't get how to manage fw-rules with l7-masking.

My router (avm fritzbox sl) got traffic shaping, too. is it important to find out the shaping rules from the router? i mean,
if i manage some traffic at the gentoo box, can it be possible, that the route manage it again with other restrictions?
maybe that's the reason why my poorly ssh stucks down when i surf the net after doing the traffic shaping howto at
gentoo-wiki.com.

thanks for help, ahorn.

Hi !
Nice How-to, but ... for me it does'nt work as I expected....

I want to limit amule upload and only upload.

so I wrote a script :

[frostschutz]

The HTB qdisc you set up on eth0 will shape everything that's sent out on eth0. So this script would only make sense if eth0 is a device that is dedicated to internet access. For shaping both up- and download with this, it would have to be some very weird network setup, like a router with only one network device (that serves both internet and LAN via eth0).

Thanks for the HowTo, but I was unable to get it up and running reffering to only this Doc. I was able to get it working after refering to a few different places for data. I figured I would post the configs that I used just so anyone else that maybe having issues with this too can give it a go.

First let me give you a little background into what I wanted to achieve. My classes are arranged like this
