limit upload bandwidth in linux

[GhettoFob]

Hi, I recently had cable internet installed and when I upload at max speed, my downloads go down dramatically. I'm wondering what programs or scripts are recommended for limiting bandwidth in linux. I did a search and basically pulled up some stuff on QoS, but I'm not sure where I should begin. BTW, I'm running Gentoo if that makes a difference. Thanks in advance.

It's usually easier just to limit the bandwidth of whatever program is hogging the bandwidth. There's usually an option in the program somewhere.

I found Wonder Shaper but when I tried to run it I get "RTNETLINK answers: Invalid argument". Does anyone have experience with this script? I think I put in QoS support in my kernel, but I'm going to recompile it now anyways.

There is more than just the QoS stuff you need for most traffic shapping. Check your config file and make sure you have:
CONFIG_NETLINK=y
CONFIG_RTNETLINK=y

The script probably also needs iproute2 installed more specifically the tc app. If you have iproute2 installed and working it is really easy to do what you want to do if you have any questions just ask.

"RTNETLINK answers: Invalid argument" doesn't mean it's not working
try it and see

You could try Trickle. Works pretty well for me.

 

[GhettoFob]

Yeah I just found trickle and I'm giving it a try and I'll also check out the config file, thanks for the help! :beer:

This is part of the verbose output from running wshaper, anyone know what it means or how I could fix it? BTW, I added those two lines to my config file and recompiled my kernel, but still no luck.

QoS is turned on? you need:
[*] QoS and/or fair queueing, and nearly everything there (use modules for shedulers if you want).

 

[GhettoFob]

Yeah I have QoS enabled and every option has an * in front of it.

 

[StuckMojo]

like i said, that message doesn't mean its not working
i use shaper, i get the same messages, but it works fine

Does anybody have something similar for windows? I need to cut a family members internet access at midnight everynight by restricting his IP address, and also if I could restrict bandwidth for the IP address that would be great too.

 

[pitupepito2000]

you could just go to your router and take away the ip that the dhcp server provided to the machine.

I hope this helps,

Another thing that you can try is setting up access lists in linux and restrict or give a higher priority to processes using an specific port for example you can give applications using port 80 a higher priority than applications using port 21 or something like that.

I hope this helps,
