Problem: We are hosting an application on remote server. We need to test it with a limited network bandwidth (for users with bad Internet access).

Question: Can I limit my internet bandwidth (in Fedora 14)? For instance: 128 KB per second.

You can throttle the network bandwidth on the interface using the command called tc Man page available at http://linux.die.net/man/8/tc

A useful script is found at


Or for more simple, use wondershaper:

If your application is exposed via http/https then you can use firefox-throttle else use NIST which is a network emulation package.

Limiting network resources based on some criterias is the subject of QoS. There are several different ways to control user traffic on Linux systems.

There is a good How-to about advanced routing techniques and traffic control on Linux by Bert Hubert.

If you already have an Apache setup somewhere, you can use mod_bw, which also works on proxied connections (i.e. Apache just forwards everything to the proper server, but slows the responses down.)

Dummynet does what you want and more, you can even control the latency, random packet loss and lots more.
